• Office 2010: It&rsquo;s not just DOC(X) and XLS(X)

  - by andrewbrust

  Office 2010 has released to manufacturing.  The bits have left the (product team’s) building.  Will you upgrade? This version of Office is officially numbered 14, a designation that correlates with the various releases, through the years, of Microsoft Word.  There were six major versions of Word for DOS, during whose release cycles came three 16-bit Windows versions.  Then, starting with Word 95 and counting through Word 2007, there have been six more versions – all for the 32-bit Windows platform.  Skip version 13 to ward off folksy bad luck (and, perhaps, the bugs that could come with it) and that brings us to version 14, which includes implementations for both 32- and 64-bit Windows platforms.  We’ve come a long way baby.  Or have we? As it does every three years or so, debate will now start to rage on over whether we need a “14th” version the PC platform’s standard word processor, or a “13th” version of the spreadsheet.  If you accept the premise of that question, then you may be on a slippery slope toward answering it in the negative.  Thing is, that premise is valid for certain customers and not others. The Microsoft Office product has morphed from one that offered core word processing, spreadsheet, presentation and email functionality to a suite of applications that provides unique, new value-added features, and even whole applications, in the context of those core services.  The core apps thus grow in mission: Excel is a BI tool.  Word is a collaborative editorial system for the production of publications.  PowerPoint is a media production platform for for live presentations and, increasingly, for delivering more effective presentations online.  Outlook is a time and task management system.  Access is a rich client front-end for data-driven self-service SharePoint applications.  OneNote helps you capture ideas, corral random thoughts in a semi-structured way, and then tie them back to other, more rigidly structured, Office documents. Google Docs and other cloud productivity platforms like Zoho don’t really do these things.  And there is a growing chorus of voices who say that they shouldn’t, because those ancillary capabilities are over-engineered, over-produced and “under-necessary.”  They might say Microsoft is layering on superfluous capabilities to avoid admitting that Office’s core capabilities, the ones people really need, have become commoditized. It’s hard to take sides in that argument, because different people, and the different companies that employ them, have different needs.  For my own needs, it all comes down to three basic questions: will the new version of Office save me time, will it make the mundane parts of my job easier, and will it augment my services to customers?  I need my time back.  I need to spend more of it with my family, and more of it focusing on my own core capabilities rather than the administrative tasks around them.  And I also need my customers to be able to get more value out of the services I provide. Help me triage my inbox, help me get proposals done more quickly and make them easier to read.  Let me get my presentations done faster, make them more effective and make it easier for me to reuse materials from other presentations.  And, since I’m in the BI and data business, help me and my customers manage data and analytics more easily, both on the desktop and online. Those are my criteria.  And, with those in mind, Office 2010 is looking like a worthwhile upgrade.  Perhaps it’s not earth-shattering, but it offers a combination of incremental improvements and a few new major capabilities that I think are quite compelling.  I provide a brief roundup of them here.  It’s admittedly arbitrary and not comprehensive, but I think it tells the Office 2010 story effectively. Across the Suite More than any other, this release of Office aims to give collaboration a real workout.  In certain apps, for the first time, documents can be opened simultaneously by multiple users, with colleagues’ changes appearing in near real-time.  Web-browser-based versions of Word, Excel, PowerPoint and OneNote will be available to extend collaboration to contributors who are off the corporate network. The ribbon user interface is now more pervasive (for example, it appears in OneNote and in Outlook’s main window).  It’s also customizable, allowing users to add, easily, buttons and options of their choosing, into new tabs, or into new groups within existing tabs. Microsoft has also taken the File menu (which was the “Office Button” menu in the 2007 release) and made it into a full-screen “Backstage” view where document-wide operations, like saving, printing and online publishing are performed. And because, more and more, heavily formatted content is cut and pasted between documents and applications, Office 2010 makes it easier to manage the retention or jettisoning of that formatting right as the paste operation is performed.  That’s much nicer than stripping it off, or adding it back, afterwards. And, speaking of pasting, a number of Office apps now make it especially easy to insert screenshots within their documents.  I know that’s useful to me, because I often document or critique applications and need to show them in action.  For the vast majority of users, I expect that this feature will be more useful for capturing snapshots of Web pages, but we’ll have to see whether this feature becomes popular.   Excel At first glance, Excel 2010 looks and acts nearly identically to the 2007 version.  But additional glances are necessary.  It’s important to understand that lots of people in the working world use Excel as more of a database, analytics and mathematical modeling tool than merely as a spreadsheet.  And it’s also important to understand that Excel wasn’t designed to handle such workloads past a certain scale.  That all changes with this release. The first reason things change is that Excel has been tuned for performance.  It’s been optimized for multi-threaded operation; previously lengthy processes have been shortened, especially for large data sets; more rows and columns are allowed and, for the first time, Excel (and the rest of Office) is available in a 64-bit version.  For Excel, this means users can take advantage of more than the 2GB of memory that the 32-bit version is limited to. On the analysis side, Excel 2010 adds Sparklines (tiny charts that fit into a single cell and can therefore be presented down an entire column or across a row) and Slicers (a more user-friendly filter mechanism for PivotTables and charts, which visually indicates what the filtered state of a given data member is).  But most important, Excel 2010 supports the new PowerPIvot add-in which brings true self-service BI to Office.  PowerPivot allows users to import data from almost anywhere, model it, and then analyze it.  Rather than forcing users to build “spreadmarts” or use corporate-built data warehouses, PowerPivot models function as true columnar, in-memory OLAP cubes that can accommodate millions of rows of data and deliver fast drill-down performance. And speaking of OLAP, Excel 2010 now supports an important Analysis Services OLAP feature called write-back.  Write-back is especially useful in financial forecasting scenarios for which Excel is the natural home.  Support for write-back is long overdue, but I’m still glad it’s there, because I had almost given up on it.   PowerPoint This version of PowerPoint marks its progression from a presentation tool to a video and photo editing and production tool.  Whether or not it’s successful in this pursuit, and if offering this is even a sensible goal, is another question. Regardless, the new capabilities are kind of interesting.  A greatly enhanced set of slide transitions with 3D effects; in-product photo and video editing; accommodation of embedded videos from services such as YouTube; and the ability to save a presentation as a video each lay testimony to PowerPoint’s transformation into a media tool and away from a pure presentation tool. These capabilities also recognize the importance of the Web as both a source for materials and a channel for disseminating PowerPoint output. Congruent with that is PowerPoint’s new ability to broadcast a slide presentation, using a quickly-generated public URL, without involving the hassle or expense of a Web meeting service like GoToMeeting or Microsoft’s own LiveMeeting.  Slides presented through this broadcast feature retain full color fidelity and transitions and animations are preserved as well.   Outlook Microsoft’s ubiquitous email/calendar/contact/task management tool gains long overdue speed improvements, especially against POP3 email accounts.  Outlook 2010 also supports multiple Exchange accounts, rather than just one; tighter integration with OneNote; and a new Social Connector providing integration with, and presence information from, online social network services like LinkedIn and Facebook (not to mention Windows Live).  A revamped conversation view now includes messages that are part of a given thread regardless of which folder they may be stored in. I don’t know yet how well the Social Connector will work or whether it will keep Outlook relevant to those who live on Facebook and LinkedIn.  But among the other features, there’s very little not to like.   OneNote To me, OneNote is the part of Office that just keeps getting better.  There is one major caveat to this, which I’ll cover in a moment, but let’s first catalog what new stuff OneNote 2010 brings.  The best part of OneNote, is the way each of its versions have managed hierarchy: Notebooks have sections, sections have pages, pages have sub pages, multiple notes can be contained in either, and each note supports infinite levels of indentation.  None of that is new to 2010, but the new version does make creation of pages and subpages easier and also makes simple work out of promoting and demoting pages from sub page to full page status.  And relationships between pages are quite easy to create now: much like a Wiki, simply typing a page’s name in double-square-brackets (“[[…]]”) creates a link to it. OneNote is also great at integrating content outside of its notebooks.  With a new Dock to Desktop feature, OneNote becomes aware of what window is displayed in the rest of the screen and, if it’s an Office document or a Web page, links the notes you’re typing, at the time, to it.  A single click from your notes later on will bring that same document or Web page back on-screen.  Embedding content from Web pages and elsewhere is also easier.  Using OneNote’s Windows Key+S combination to grab part of the screen now allows you to specify the destination of that bitmap instead of automatically creating a new note in the Unfiled Notes area.  Using the Send to OneNote buttons in Internet Explorer and Outlook result in the same choice. Collaboration gets better too.  Real-time multi-author editing is better accommodated and determining author lineage of particular changes is easily carried out. My one pet peeve with OneNote is the difficulty using it when I’m not one a Windows PC.  OneNote’s main competitor, Evernote, while I believe inferior in terms of features, has client versions for PC, Mac, Windows Mobile, Android, iPhone, iPad and Web browsers.  Since I have an Android phone and an iPad, I am practically forced to use it.  However, the OneNote Web app should help here, as should a forthcoming version of OneNote for Windows Phone 7.  In the mean time, it turns out that using OneNote’s Email Page ribbon button lets you move a OneNote page easily into EverNote (since every EverNote account gets a unique email address for adding notes) and that Evernote’s Email function combined with Outlook’s Send to OneNote button (in the Move group of the ribbon’s Home tab) can achieve the reverse.   Access To me, the big change in Access 2007 was its tight integration with SharePoint lists.  Access 2010 and SharePoint 2010 continue this integration with the introduction of SharePoint’s Access Services.  Much as Excel Services provides a SharePoint-hosted experience for viewing (and now editing) Excel spreadsheet, PivotTable and chart content, Access Services allows for SharePoint browser-hosted editing of Access data within the forms that are built in the Access client itself. To me this makes all kinds of sense.  Although it does beg the question of where to draw the line between Access, InfoPath, SharePoint list maintenance and SharePoint 2010’s new Business Connectivity Services.  Each of these tools provide overlapping data entry and data maintenance functionality. But if you do prefer Access, then you’ll like  things like templates and application parts that make it easier to get off the blank page.  These features help you quickly get tables, forms and reports built out.  To make things look nice, Access even gets its own version of Excel’s Conditional Formatting feature, letting you add data bars and data-driven text formatting.   Word As I said at the beginning of this post, upgrades to Office are about much more than enhancing the suite’s flagship word processing application. So are there any enhancements in Word worth mentioning?  I think so.  The most important one has to be the collaboration features.  Essentially, when a user opens a Word document that is in a SharePoint document library (or Windows Live SkyDrive folder), rather than the whole document being locked, Word has the ability to observe more granular locks on the individual paragraphs being edited.  Word also shows you who’s editing what and its Save function morphs into a sync feature that both saves your changes and loads those made by anyone editing the document concurrently. There’s also a new navigation pane that lets you manage sections in your document in much the same way as you manage slides in a PowerPoint deck.  Using the navigation pane, you can reorder sections, insert new ones, or promote and demote sections in the outline hierarchy.  Not earth shattering, but nice.   Other Apps and Summarized Findings What about InfoPath, Publisher, Visio and Project?  I haven’t looked at them yet.  And for this post, I think that’s fine.  While those apps (and, arguably, Access) cater to specific tasks, I think the apps we’ve looked at in this post service the general purpose needs of most users.  And the theme in those 2010 apps is clear: collaboration is key, the Web and productivity are indivisible, and making data and analytics into a self-service amenity is the way to go.  But perhaps most of all, features are still important, as long as they get you through your day faster, rather than adding complexity for its own sake.  I would argue that this is true for just about every product Microsoft makes: users want utility, not complexity.

• OIM 11g : Multi-thread approach for writing custom scheduled job

  - by Saravanan V S

  In this post I have shared my experience of designing and developing an OIM schedule job that uses multi threaded approach for updating data in OIM using APIs.  I have used thread pool (in particular fixed thread pool) pattern in developing the OIM schedule job. The thread pooling pattern has noted advantages compared to thread per task approach. I have listed few of the advantage here ·         Threads are reused ·         Creation and tear-down cost of thread is reduced ·         Task execution latency is reduced ·         Improved performance ·         Controlled and efficient management of memory and resources used by threads More about java thread pool http://docs.oracle.com/javase/tutorial/essential/concurrency/pools.html The following diagram depicts the high-level architectural diagram of the schedule job that process input from a flat file to update OIM process form data using fixed thread pool approach    The custom scheduled job shared in this post is developed to meet following requirement 1)      Need to process a CSV extract that contains identity, account identifying key and list of data to be updated on an existing OIM resource account. 2)      CSV file can contain data for multiple resources configured in OIM 3)      List of attribute to update and mapping between CSV column to OIM fields may vary between resources The following are three Java class developed for this requirement (I have given only prototype of the code that explains how to use thread pools in schedule task) CustomScheduler.java - Implementation of TaskSupport class that reads and passes the parameters configured on the schedule job to Thread Executor class. package com.oracle.oim.scheduler; import java.util.HashMap; import com.oracle.oim.bo.MultiThreadDataRecon; import oracle.iam.scheduler.vo.TaskSupport; public class CustomScheduler extends TaskSupport {      public void execute(HashMap options) throws Exception {             /*  Read Schedule Job Parameters */             String param1 = (String) options.get(“Parameter1”);             .             int noOfThread = (int) options.get(“No of Threads”);             .             String paramn = (int) options.get(“ParamterN”); /* Provide all the required input configured on schedule job to Thread Pool Executor implementation class like 1) Name of the file, 2) Delimiter 3) Header Row Numer 4) Line Escape character 5) Config and resource map lookup 6) No the thread to create */ new MultiThreadDataRecon(all_required_parameters, noOfThreads).reconcile();       }       public HashMap getAttributes() { return null; }       public void setAttributes() {       } } MultiThreadDataRecon.java – Helper class that reads data from input file, initialize the thread executor and builds the task queue. package com.oracle.oim.bo;

            } else {                   threadExecutor = Executors.newSingleThreadExecutor();             }             /* Initialize TaskProcess clas s which will be executing task                 from the Queue */                TaskProcessor.initializeConfig(params);       } catch (***Exception e) {                   // TO DO       }  }       /**        *  Method to reconcile data from CSV to OIM        */ public void reconcile() throws Exception {        try {             init();             while(<csv file has line>){                   processRow(line);             }             /* Initiate thread shutdown */             threadExecutor.shutdown();             while (!threadExecutor.isTerminated()) {                 // Wait for all task to complete.             }            } catch (Exception e) {                   // TO DO            } finally {                   try {                         //Close all the file handles                   } catch (IOException e) {                         //TO DO                   }             }       }       /**        * Method to process         */       private void processRow(String row) {             // Create task processor instance with the row data              // Following code push the task to work queue and wait for next                available thread to execute             threadExecutor.execute(new TaskProcessor(rowData));

• WTSQuerySessionInformation returning empty strings

  - by Benj

  I've written a program which should query the Terminal Services API and print out some state information about the sessions running on a terminal services box. I'm using the WTSQuerySessionInformation function to do this and it's returning some data but most of the data seems to be missing... Does anyone know why? Here's my program: void WTSGetString( HANDLE serverHandle, DWORD sessionid, WTS_INFO_CLASS command, wchar_t* commandStr) { DWORD bytesReturned = 0; LPTSTR pData = NULL; if (WTSQuerySessionInformation(serverHandle, sessionid, command, &pData, &bytesReturned)) { wprintf(L"\tWTSQuerySessionInformationW - session %d - %s returned \"%s\"\n", sessionid, commandStr, pData); } else { wprintf(L"\tWTSQuerySessionInformationW - session %d - %s failed - error=%d - ", sessionid, commandStr, GetLastError()); printLastError(NULL, GetLastError()); } WTSFreeMemory(pData); } void ExtractFromWTS( HANDLE serverHandle, DWORD sessionid ) { WTSGetString(serverHandle, sessionid, WTSInitialProgram, L"WTSInitialProgram"); WTSGetString(serverHandle, sessionid, WTSApplicationName, L"WTSApplicationName"); WTSGetString(serverHandle, sessionid, WTSWorkingDirectory, L"WTSWorkingDirectory"); WTSGetString(serverHandle, sessionid, WTSOEMId, L"WTSOEMId"); WTSGetString(serverHandle, sessionid, WTSSessionId, L"WTSSessionId"); WTSGetString(serverHandle, sessionid, WTSUserName, L"WTSUserName"); WTSGetString(serverHandle, sessionid, WTSWinStationName, L"WTSWinStationName"); WTSGetString(serverHandle, sessionid, WTSDomainName, L"WTSDomainName"); WTSGetString(serverHandle, sessionid, WTSConnectState, L"WTSConnectState"); WTSGetString(serverHandle, sessionid, WTSClientBuildNumber, L"WTSClientBuildNumber"); WTSGetString(serverHandle, sessionid, WTSClientName, L"WTSClientName"); WTSGetString(serverHandle, sessionid, WTSClientDirectory, L"WTSClientDirectory"); WTSGetString(serverHandle, sessionid, WTSClientProductId, L"WTSClientProductId"); WTSGetString(serverHandle, sessionid, WTSClientHardwareId, L"WTSClientHardwareId"); WTSGetString(serverHandle, sessionid, WTSClientAddress, L"WTSClientAddress"); WTSGetString(serverHandle, sessionid, WTSClientDisplay, L"WTSClientDisplay"); WTSGetString(serverHandle, sessionid, WTSClientProtocolType, L"WTSClientProtocolType"); } int _tmain(int argc, _TCHAR* argv[]) { PWTS_SESSION_INFOW ppSessionInfo = 0; DWORD pCount; if(!WTSEnumerateSessions(WTS_CURRENT_SERVER_HANDLE, 0, 1, &ppSessionInfo, &pCount)) { printLastError(L"WTSEnumerateSessions", GetLastError()); return 1; } wprintf(L"%d WTS sessions found on host\n", pCount); for (unsigned int i=0; i<pCount; i++) { wprintf(L"> session=%d, stationName = %s\n", ppSessionInfo[i].SessionId, ppSessionInfo[i].pWinStationName); ExtractFromWTS(WTS_CURRENT_SERVER_HANDLE, ppSessionInfo[i].SessionId); LPWSTR sessionstr = new wchar_t[200]; wsprintf(sessionstr, L"%d", ppSessionInfo[i].SessionId); } return 0; } And here's the output: C:\Users\Administrator\Desktop>ObtainWTSStartShell.exe empserver1 4 WTS sessions found on host > session=0, stationName = Services WTSQuerySessionInformationW - session 0 - WTSInitialProgram failed - error=87 - The paramete r is incorrect.

• Help with Design for Vacation Tracking System (C#/.NET/Access/WebServices/SOA/Excel) [closed]

  - by Aaronaught

  I have been tasked with developing a system for tracking our company's paid time-off (vacation, sick days, etc.) At the moment we are using an Excel spreadsheet on a shared network drive, and it works pretty well, but we are concerned that we won't be able to "trust" employees forever and sometimes we run into locking issues when two people try to open the spreadsheet at once. So we are trying to build something a little more robust. I would like some input on this design in terms of maintainability, scalability, extensibility, etc. It's a pretty simple workflow we need to represent right now: I started with a basic MS Access schema like this: Employees (EmpID int, EmpName varchar(50), AllowedDays int) Vacations (VacationID int, EmpID int, BeginDate datetime, EndDate datetime) But we don't want to spend a lot of time building a schema and database like this and have to change it later, so I think I am going to go with something that will be easier to expand through configuration. Right now the vacation table has this schema: Vacations (VacationID int, PropName varchar(50), PropValue varchar(50)) And the table will be populated with data like this: VacationID | PropName | PropValue -----------+--------------+------------------ 1 | EmpID | 4 1 | EmpName | James Jones 1 | Reason | Vacation 1 | BeginDate | 2/24/2010 1 | EndDate | 2/30/2010 1 | Destination | Spectate Swamp 2 | ... | ... I think this is a pretty good, extensible design, we can easily add new properties to the vacation like the destination or maybe approval status, etc. I wasn't too sure how to go about managing the database of valid properties, I thought of putting them in a separate PropNames table but it gets complicated to manage all the different data types and people say that you shouldn't put CLR type names into a SQL database, so I decided to use XML instead, here is the schema: <VacationProperties> <PropertyNames>EmpID,EmpName,Reason,BeginDate,EndDate,Destination</PropertyNames> <PropertyTypes>System.Int32,System.String,System.String,System.DateTime,System.DateTime,System.String</PropertyTypes> <PropertiesRequired>true,true,false,true,true,false</PropertiesRequired> </VacationProperties> I might need more fields than that, I'm not completely sure. I'm parsing the XML like this (would like some feedback on the parsing code): string xml = File.ReadAllText("properties.xml"); Match m = Regex.Match(xml, "<(PropertyNames)>(.*?)</PropertyNames>"; string[] pn = m.Value.Split(','); // do the same for PropertyTypes, PropertiesRequired Then I use the following code to persist configuration changes to the database: string sql = "DROP TABLE VacationProperties"; sql = sql + " CREATE TABLE VacationProperties "; sql = sql + "(PropertyName varchar(100), PropertyType varchar(100) "; sql = sql + "IsRequired varchar(100))"; for (int i = 0; i < pn.Length; i++) { sql = sql + " INSERT VacationProperties VALUES (" + pn[i] + "," + pt[i] + "," + pv[i] + ")"; } // GlobalConnection is a singleton new SqlCommand(sql, GlobalConnection.Instance).ExecuteReader(); So far so good, but after a few days of this I then realized that a lot of this was just a more specific kind of a generic workflow which could be further abstracted, and instead of writing all of this boilerplate plumbing code I could just come up with a workflow and plug it into a workflow engine like Windows Workflow Foundation and have the users configure it: In order to support routing these configurations throw the workflow system, it seemed natural to implement generic XML Web Services for this instead of just using an XML file as above. I've used this code to implement the Web Services: public class VacationConfigurationService : WebService { [WebMethod] public void UpdateConfiguration(string xml) { // Above code goes here } } Which was pretty easy, although I'm still working on a way to validate that XML against some kind of schema as there's no error-checking yet. I also created a few different services for other operations like VacationSubmissionService, VacationReportService, VacationDataService, VacationAuthenticationService, etc. The whole Service Oriented Architecture looks like this: And because the workflow itself might change, I have been working on a way to integrate the WF workflow system with MS Visio, which everybody at the office already knows how to use so they could make changes pretty easily. We have a diagram that looks like the following (it's kind of hard to read but the main items are Activities, Authenticators, Validators, Transformers, Processors, and Data Connections, they're all analogous to the services in the SOA diagram above). The requirements for this system are: (Note - I don't control these, they were given to me by management) Main workflow must interface with Excel spreadsheet, probably through VBA macros (to ease the transition to the new system) Alerts should integrate with MS Outlook, Lotus Notes, and SMS (text messages). We also want to interface it with the company Voice Mail system but that is not a "hard" requirement. Performance requirements: Must handle 250,000 Transactions Per Second Should be able to handle up to 20,000 employees (right now we have 3) 99.99% uptime ("four nines") expected Must be secure against outside hacking, but users cannot be required to enter a username/password. Platforms: Must support Windows XP/Vista/7, Linux, iPhone, Blackberry, DOS 2.0, VAX, IRIX, PDP-11, Apple IIc. Time to complete: 6 to 8 weeks. My questions are: Is this a good design for the system so far? Am I using all of the recommended best practices for these technologies? How do I integrate the Visio diagram above with the Windows Workflow Foundation to call the ConfigurationService and persist workflow changes? Am I missing any important components? Will this be extensible enough to support any scenario via end-user configuration? Will the system scale to the above performance requirements? Will we need any expensive hardware to run it? Are there any "gotchas" I should know about with respect to cross-platform compatibility? For example would it be difficult to convert this to an iPhone app? How long would you expect this to take? (We've dedicated 1 week for testing so I'm thinking maybe 5 weeks?) Many thanks for your advices, Aaron

• WCF: Server Not Found - from trace Empty Message when run async but works fine from console app?

  - by MrTortoise

  Todays cause of hair loss has been the following scenario: I have a service that takes 2 strings and returns another. This service uses basicHttpBinding <basicHttpBinding> <binding name="basicHttpNoSec"> <security mode="None" /> </binding> </basicHttpBinding> Anyway, it works fine from a console test app. I have a silverlight app sat on top which implements another basicHttpBinding service that simply reuses the contract in the other service and the silverlight App uses this service. I have a console app that confirms that this service is working and set up with basichttpbinding. I have all the clientAccessPolicy stuff in place. when I run the silverlight app the difference is that it runs everything async ... as such the only message i directly get back rom wcf is server not found. When i enable tracing I dig down to this message - as I know the methods work and the parameteres i pass in will return a valid string i am really puzzled at to what the cause is. any help much appreciated. <E2ETraceEvent xmlns="http://schemas.microsoft.com/2004/06/E2ETraceEvent"> <System xmlns="http://schemas.microsoft.com/2004/06/windows/eventlog/system"> <EventID>131075</EventID> <Type>3</Type> <SubType Name="Error">0</SubType> <Level>2</Level> <TimeCreated SystemTime="2010-06-07T14:17:40.6639249Z" /> <Source Name="System.ServiceModel" /> <Correlation ActivityID="{8ea9530e-12f4-4a82-9c26-dd2e23264c3c}" /> <Execution ProcessName="aspnet_wp" ProcessID="4616" ThreadID="6" /> <Channel /> <Computer>5JC2Y2J</Computer> </System> <ApplicationData> <TraceData> <DataItem> <TraceRecord xmlns="http://schemas.microsoft.com/2004/10/E2ETraceEvent/TraceRecord" Severity="Error"> <TraceIdentifier>http://msdn.microsoft.com/en-GB/library/System.ServiceModel.Diagnostics.ThrowingException.aspx</TraceIdentifier> <Description>Throwing an exception.</Description> <AppDomain>/LM/w3svc/1/ROOT/CopSilverlight.Web-1-129203938565564172</AppDomain> <Exception> <ExceptionType>System.ServiceModel.ProtocolException, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</ExceptionType> <Message>There is a problem with the XML that was received from the network.

• Hibernate : load and

  - by Albert Kam

  According to the tutorial : http://jpa.ezhibernate.com/Javacode/learn.jsp?tutorial=27hibernateloadvshibernateget, If you initialize a JavaBean instance with a load method call, you can only access the properties of that JavaBean, for the first time, within the transactional context in which it was initialized. If you try to access the various properties of the JavaBean after the transaction that loaded it has been committed, you'll get an exception, a LazyInitializationException, as Hibernate no longer has a valid transactional context to use to hit the database. But with my experiment, using hibernate 3.6, and postgres 9, it doesnt throw any exception at all. Am i missing something ? Here's my code : import org.hibernate.Session; public class AppLoadingEntities { /** * @param args */ public static void main(String[] args) { HibernateUtil.beginTransaction(); Session session = HibernateUtil.getSession(); EntityUser userFromGet = get(session); EntityUser userFromLoad = load(session); // finish the transaction session.getTransaction().commit(); // try fetching field value from entity bean that is fetched via get outside transaction, and it'll be okay System.out.println("userFromGet.getId() : " + userFromGet.getId()); System.out.println("userFromGet.getName() : " + userFromGet.getName()); // fetching field from entity bean that is fetched via load outside transaction, and it'll be errornous // NOTE : but after testing, load seems to be okay, what gives ? ask forums try { System.out.println("userFromLoad.getId() : " + userFromLoad.getId()); System.out.println("userFromLoad.getName() : " + userFromLoad.getName()); } catch(Exception e) { System.out.println("error while fetching entity that is fetched from load : " + e.getMessage()); } } private static EntityUser load(Session session) { EntityUser user = (EntityUser) session.load(EntityUser.class, 1l); System.out.println("user fetched with 'load' inside transaction : " + user); return user; } private static EntityUser get(Session session) { // safe to set it to 1, coz the table got recreated at every run of this app EntityUser user = (EntityUser) session.get(EntityUser.class, 1l); System.out.println("user fetched with 'get' : " + user); return user; } } And here's the output : 88 [main] INFO org.hibernate.annotations.common.Version - Hibernate Commons Annotations 3.2.0.Final 93 [main] INFO org.hibernate.cfg.Environment - Hibernate 3.6.0.Final 94 [main] INFO org.hibernate.cfg.Environment - hibernate.properties not found 96 [main] INFO org.hibernate.cfg.Environment - Bytecode provider name : javassist 98 [main] INFO org.hibernate.cfg.Environment - using JDK 1.4 java.sql.Timestamp handling 139 [main] INFO org.hibernate.cfg.Configuration - configuring from resource: /hibernate.cfg.xml 139 [main] INFO org.hibernate.cfg.Configuration - Configuration resource: /hibernate.cfg.xml 172 [main] WARN org.hibernate.util.DTDEntityResolver - recognized obsolete hibernate namespace http://hibernate.sourceforge.net/.

• Initializing SD card in SPI issues

  - by Sembazuru

  Sorry for the length of this question, but I thought it best to show as much detail to fend of questions asking if I had done A when I had already done A... ;-) I've had a look at the "micro-SD card initialization using SPI interface" thread and didn't see any answers that matched my issue (i.e. things I haven't already tried). I have a similar issue where I'm trying to access a SD card through a micro-controller's SPI interface (specifically an HC908). I've tried following the flow charts in the Physical Layer Simplified Specification v2.00 and it seems to initialize correctly on Transcend 1GB & 2GB and an AE&C 1GB card. But I'm having problems on 3 other random cards from my stash of old cards that I've used on my camera. My code is all HC908 assembler. I scoped out the SPI clock line and during initialization it's running about 350kHz (the only speed multiplier that the HC908 supplies at my low MCU clock speed that falls within the 100-400kHz window). Here are the results of the three cards that aren't completing my initialization routine (all done consecutively w/o changing any code or timing parameters): Canon 16Meg card (labeled as SD): Set card select high Send 80 SPI clock cycles (done by writing 0xFF 10 times) Set card select low Send CMD0 [0x400000000095] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (indicates idle) Send CMD8 [0x48000001AA87] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command) Because illegal command set local flag to indicate v1 or MMC card Send CMD58 [0x7A00000000FD] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command) because illegal command branch to error routine Send CMD13 [0x4D000000000D] (show status buffer) and Loop up to 8 times waiting for high bit on response to go low R1= 0x05 (idle and illegal command) Is the illegal command flag stuck? Should I be doing something after CMD8 to clear that flag? SanDisk UltraII 256Meg Set card select high Send 80 SPI clock cycles (done by writing 0xFF 10 times) Set card select low Send CMD0 [0x400000000095] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle) Send CMD8 [0x48000001AA87] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command) Because illegal command set local flag to indicate v1 or MMC card Send CMD58 [0x7A00000000FD] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle) Send 0xFF 4 times to read OCR OCR = 0xFFFFFFFF Send CMD55 [0x770000000065] (1st part of ACMD41) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle) Send CMD41 [0x6900000000E5] (2nd part of ACMD41) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command) Because illegal command, assume card is MMC Send CMD1 [0x4100000000F9] (for MMC) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command) Repeat the CMD1 50 times (my arbitrary number to wait until idle clears) Every R1 response is 0x05 (idle and illegal command) Why is OCR all F? Doesn't seem proper at all. Also, why does ACMD41 and CMD1 respond illegal command? Is CMD1 failing because the card is waiting for a valid ACMD after the CMD55 even with the illegal command response? SanDisk ExtremeIII 2G: Set card select high Send 80 SPI clock cycles (done by writing 0xFF 10 times) Set card select low Send CMD0 [0x400000000095] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle) Send CMD8 [0x40000001AA87] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x7F (??? My loop shows the responses for each iteration and I got 0xFF 0xFF 0xC1 0x7F... is the card getting out of sync?) Send CMD58 [0x7A00000000FD] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle and back in sync) Send 0xFF 4 times to read OCR OCR = 0x00FF80 Send CMD55 [0x770000000065] (1st part of ACMD41) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x5F (??? loop responses are 0xFF 0xFF 0xF0 0x5F... again out of sync?) Send CMD41 [0x6900000000E5] (2nd part of ACMD41) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command, but back in sync???) Because illegal command, assume card is MMC Send CMD1 [0x4100000000F9] (for MMC) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x7F (??? loop responses are 0xFF 0xFF 0xC1 0x7F... again out of sync?) Repeat CMD1 and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle) Repeat CMD1 and Loop up to 8 times waiting for high bit on response to go low R1 = 0x7F (??? loop responses are 0xFF 0xFF 0xC1 0x7F... again out of sync?) Repeat CMD1 and Loop up to 8 times waiting for high bit on response to go low R1 = 0x00 (out of idle) Send CMD9 [0x4900000000AF] (get CSD) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x3F (??? loop responses are 0xFF 0xFF 0xC1 0x3F... again out of sync?) Code craps out because Illegal command bit is high. WTF is wrong with that card? Sometimes in sync, other times not. (The above pattern is repeatable.) I've scoped this one out and I'm not seeing any rogue clock cycles going through between MOSI/MISO transfers. Anyone have any clues? Need any more info? Thanx in advance for spending the time to read through all of this.

• From AutoComplete textbox to database search and display?

  - by svebee

  Hello everyone, I have a small problem so I would be grateful if anyone could help me in any way. Thank you ;) I have this little "application", and I want when someone type in a AutoComplete textbox for example "New" it automatically displays "New York" as a option and that (AutoComplete function) works fine. But I want when user type in full location (or AutoComplete do it for him) - that text (location) input is forwarded to a database search which then searches through database and "collects" all rows with user-typed location. For example if user typed in "New York", database search would find all rows with "New York" in it. When it finds one/more row(s) it would display them below. In images...

• Design for Vacation Tracking System

  - by Aaronaught

  I have been tasked with developing a system for tracking our company's paid time-off (vacation, sick days, etc.) At the moment we are using an Excel spreadsheet on a shared network drive, and it works pretty well, but we are concerned that we won't be able to "trust" employees forever and sometimes we run into locking issues when two people try to open the spreadsheet at once. So we are trying to build something a little more robust. I would like some input on this design in terms of maintainability, scalability, extensibility, etc. It's a pretty simple workflow we need to represent right now: I started with a basic MS Access schema like this: Employees (EmpID int, EmpName varchar(50), AllowedDays int) Vacations (VacationID int, EmpID int, BeginDate datetime, EndDate datetime) But we don't want to spend a lot of time building a schema and database like this and have to change it later, so I think I am going to go with something that will be easier to expand through configuration. Right now the vacation table has this schema: Vacations (VacationID int, PropName varchar(50), PropValue varchar(50)) And the table will be populated with data like this: VacationID | PropName | PropValue -----------+--------------+------------------ 1 | EmpID | 4 1 | EmpName | James Jones 1 | Reason | Vacation 1 | BeginDate | 2/24/2010 1 | EndDate | 2/30/2010 1 | Destination | Spectate Swamp 2 | ... | ... I think this is a pretty good, extensible design, we can easily add new properties to the vacation like the destination or maybe approval status, etc. I wasn't too sure how to go about managing the database of valid properties, I thought of putting them in a separate PropNames table but it gets complicated to manage all the different data types and people say that you shouldn't put CLR type names into a SQL database, so I decided to use XML instead, here is the schema: <VacationProperties> <PropertyNames>EmpID,EmpName,Reason,BeginDate,EndDate,Destination</PropertyNames> <PropertyTypes>System.Int32,System.String,System.String,System.DateTime,System.DateTime,System.String</PropertyTypes> <PropertiesRequired>true,true,false,true,true,false</PropertiesRequired> </VacationProperties> I might need more fields than that, I'm not completely sure. I'm parsing the XML like this (would like some feedback on the parsing code): string xml = File.ReadAllText("properties.xml"); Match m = Regex.Match(xml, "<(PropertyNames)>(.*?)</PropertyNames>"; string[] pn = m.Value.Split(','); // do the same for PropertyTypes, PropertiesRequired Then I use the following code to persist configuration changes to the database: string sql = "DROP TABLE VacationProperties"; sql = sql + " CREATE TABLE VacationProperties "; sql = sql + "(PropertyName varchar(100), PropertyType varchar(100) "; sql = sql + "IsRequired varchar(100))"; for (int i = 0; i < pn.Length; i++) { sql = sql + " INSERT VacationProperties VALUES (" + pn[i] + "," + pt[i] + "," + pv[i] + ")"; } // GlobalConnection is a singleton new SqlCommand(sql, GlobalConnection.Instance).ExecuteReader(); So far so good, but after a few days of this I then realized that a lot of this was just a more specific kind of a generic workflow which could be further abstracted, and instead of writing all of this boilerplate plumbing code I could just come up with a workflow and plug it into a workflow engine like Windows Workflow Foundation and have the users configure it: In order to support routing these configurations throw the workflow system, it seemed natural to implement generic XML Web Services for this instead of just using an XML file as above. I've used this code to implement the Web Services: public class VacationConfigurationService : WebService { [WebMethod] public void UpdateConfiguration(string xml) { // Above code goes here } } Which was pretty easy, although I'm still working on a way to validate that XML against some kind of schema as there's no error-checking yet. I also created a few different services for other operations like VacationSubmissionService, VacationReportService, VacationDataService, VacationAuthenticationService, etc. The whole Service Oriented Architecture looks like this: And because the workflow itself might change, I have been working on a way to integrate the WF workflow system with MS Visio, which everybody at the office already knows how to use so they could make changes pretty easily. We have a diagram that looks like the following (it's kind of hard to read but the main items are Activities, Authenticators, Validators, Transformers, Processors, and Data Connections, they're all analogous to the services in the SOA diagram above). The requirements for this system are: (Note - I don't control these, they were given to me by management) Main workflow must interface with Excel spreadsheet, probably through VBA macros (to ease the transition to the new system) Alerts should integrate with MS Outlook, Lotus Notes, and SMS (text messages). We also want to interface it with the company Voice Mail system but that is not a "hard" requirement. Performance requirements: Must handle 250,000 Transactions Per Second Should be able to handle up to 20,000 employees (right now we have 3) 99.99% uptime ("four nines") expected Must be secure against outside hacking, but users cannot be required to enter a username/password. Platforms: Must support Windows XP/Vista/7, Linux, iPhone, Blackberry, DOS 2.0, VAX, IRIX, PDP-11, Apple IIc. Time to complete: 6 to 8 weeks. My questions are: Is this a good design for the system so far? Am I using all of the recommended best practices for these technologies? How do I integrate the Visio diagram above with the Windows Workflow Foundation to call the ConfigurationService and persist workflow changes? Am I missing any important components? Will this be extensible enough to support any scenario via end-user configuration? Will the system scale to the above performance requirements? Will we need any expensive hardware to run it? Are there any "gotchas" I should know about with respect to cross-platform compatibility? For example would it be difficult to convert this to an iPhone app? How long would you expect this to take? (We've dedicated 1 week for testing so I'm thinking maybe 5 weeks?)

• Delphi Pascal - Using SetFilePointerEx and GetFileSizeEx, Getting Physical Media exact size when reading as a file

  - by SuicideClutchX2

  I am having trouble understanding how to delcare GetFileSizeEx and SetFilePointerEx in Delphi 2009 so that I can use them since they are not in the RTL or Windows.pas. I was able to compile with the following: function GetFileSizeEx(hFile: THandle; lpFileSizeHigh: Pointer): DWORD; external 'kernel32'; Then using GetFileSizeEx(PD, Pointer(DriveSize)); to get the size. But could not get it to work, the disk handle I am using is valid and I have had no problem reading the data or working under the 2gb mark with the older API's. GetFileSize of course returns 4294967295. I have had greater trouble trying to use SetFilePointerEx with the data types it uses. The overall project needs to read the data from a flash card, which is not a problem at all I can do this. My problem is that I can not find the length or size of the media I will be reading. I have code I have used in the past to do this with media under 2GB. But now that I need to read media over 2GB it is a problem. If you still dont understand I am dumping a card with all data including the boot record, etc. This is the code I would normally use to read from the physical disk to grab say the boot record and dump it to file: SetFilePointer(PD,0,nil,FILE_BEGIN); SetLength(Buffer,512); ReadFile(PD,Buffer[0],512,BytesReturned,nil); I just need to figure out how to find the end of an 8gb card and so on as well as being able to set a file pointer beyond the 2gb barrier. I guess any help in the external declarations as well as understand the values that SetFilePointerEx uses (I do not understand the whole High Low thing) would be of great help. var Form1: TForm1; function GetFileSizeEx(hFile: THandle; var FileSize: Int64): DWORD; stdcall; external 'kernel32'; implementation {$R *.dfm} function GetLD(Drive: Char): Cardinal; var Buffer : String; begin Buffer := Format('\\.\%s:',[Drive]); Result := CreateFile(PChar(Buffer),GENERIC_READ Or GENERIC_WRITE,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); If Result = INVALID_HANDLE_VALUE Then begin Result := CreateFile(PChar(Buffer),GENERIC_READ,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); end; end; function GetPD(Drive: Byte): Cardinal; var Buffer : String; begin If Drive = 0 Then begin Result := INVALID_HANDLE_VALUE; Exit; end; Buffer := Format('\\.\PHYSICALDRIVE%d',[Drive]); Result := CreateFile(PChar(Buffer),GENERIC_READ Or GENERIC_WRITE,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); If Result = INVALID_HANDLE_VALUE Then begin Result := CreateFile(PChar(Buffer),GENERIC_READ,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); end; end; function GetPhysicalDiskNumber(Drive: Char): Byte; var LD : DWORD; DiskExtents : PVolumeDiskExtents; DiskExtent : TDiskExtent; BytesReturned : Cardinal; begin Result := 0; LD := GetLD(Drive); If LD = INVALID_HANDLE_VALUE Then Exit; Try DiskExtents := AllocMem(Max_Path); DeviceIOControl(LD,IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS,nil,0,DiskExtents,Max_Path,BytesReturned,nil); If DiskExtents^.NumberOfDiskExtents > 0 Then begin DiskExtent := DiskExtents^.Extents[0]; Result := DiskExtent.DiskNumber; end; Finally CloseHandle(LD); end; end; procedure TForm1.Button1Click(Sender: TObject); var PD : DWORD; BytesReturned : Cardinal; Buffer : Array Of Byte; myFile: File; DriveSize: Int64; begin PD := GetPD(GetPhysicalDiskNumber(Edit1.Text[1])); If PD = INVALID_HANDLE_VALUE Then Exit; Try GetFileSizeEx(PD, DriveSize); //SetFilePointer(PD,0,nil,FILE_BEGIN); //etLength(Buffer,512); //ZeroMemory(@Buffer,SizeOf(Buffer)); //ReadFile(PD,Buffer[0],512,BytesReturned,nil); //AssignFile(myFile, 'StickDump.bin'); //ReWrite(myFile, 512); //BlockWrite(myFile, Buffer[0], 1); //CloseFile(myFile); Finally CloseHandle(PD); End; end;

• Windows 2008 RenderFarm Service: CreateProcessAsUser "Session 0 Isolation" and OpenGL

  - by holtavolt

  Hello, I have a legacy Windows server service and (spawned) application that works fine in XP-64 and W2K3, but fails on W2K8. I believe it is because of the new "Session 0 isolation " feature. (Note: As a StackOverflow newbie I'm being limited to one link in this post, so you'll need to scroll to bottom to lookup the links for '' items)* Consequently, I'm looking for code samples/security settings mojo that let you create a new process from a windows service for Windows 2008 Server such that I can restore (and possibly surpass) the previous behavior. I need a solution that: Creates the new process in a non-zero session to get around session-0 isolation restrictions (no access to graphics hardware from session 0) - the official MS line on this is: Because Session 0 is no longer a user session, services that are running in Session 0 do not have access to the video driver. This means that any attempt that a service makes to render graphics fails. Querying the display resolution and color depth in Session 0 reports the correct results for the system up to a maximum of 1920x1200 at 32 bits per pixel. The new process gets a windows station/desktop (e.g. winsta0/default) that can be used to create windows DCs. I've found a solution (that launches OK in an interactive session) for this here: *(Starting an Interactive Client Process in C++ - 2) The windows DC, when used as the basis for an *(OpenGL DescribePixelFormat enumeration - 3), is able to find and use the hardware-accelerated format (on a system appropriately equipped with OpenGL hardware.) Note that our current solution works OK on XP-64 and W2K3, except if a terminal services session is running (VNC works fine.) A solution that also allowed the process to work (i.e. run with OpenGL hardware acceleration even when a terminal services session is open) would be fanastic, although not required. I'm stuck at item #1 currently, and although there are some similar postings that discuss this (like *(this -4), and *(this - 5) - they are not suitable solutions, as there is no guarantee of a user session logged in already to "take" a session id from, nor am I running from a LocalSystem account (I'm running from a domain account for the service, for which I can adjust the privileges of, within reason, although I'd prefer to not have to escalate priorities to include SeTcbPrivileges.) For instance - here's a stub that I think should work, but always returns an error 1314 on the SetTokenInformation call (even though the AdjustTokenPrivileges returned no errors) I've used some alternate strategies involving "LogonUser" as well (instead of opening the existing process token), but I can't seem to swap out the session id. I'm also dubious about using the WTSActiveConsoleSessionId in all cases (for instance, if no interactive user is logged in) - although a quick test of the service running with no sessions logged in seemed to return a reasonable session value (1). I’ve removed error handling for ease of reading (still a bit messy - apologies) //Also tried using LogonUser(..) here OpenProcessToken(GetCurrentProcess(), TOKEN_QUERY | TOKEN_ADJUST_PRIVILEGES | TOKEN_ADJUST_SESSIONID | TOKEN_ADJUST_DEFAULT | TOKEN_ASSIGN_PRIMARY | TOKEN_DUPLICATE, &hToken) GetTokenInformation( hToken, TokenSessionId, &logonSessionId, sizeof(DWORD), &dwTokenLength ) DWORD consoleSessionId = WTSGetActiveConsoleSessionId(); /* Can't use this - requires very elevated privileges (LOCAL only, SeTcbPrivileges as well) if( !WTSQueryUserToken(consoleSessionId, &hToken)) ... */ DuplicateTokenEx(hToken, (TOKEN_QUERY | TOKEN_ADJUST_PRIVILEGES | TOKEN_ADJUST_SESSIONID | TOKEN_ADJUST_DEFAULT | TOKEN_ASSIGN_PRIMARY | TOKEN_DUPLICATE), NULL, SecurityIdentification, TokenPrimary, &hDupToken)) // Look up the LUID for the TCB Name privilege. LookupPrivilegeValue(NULL, SE_TCB_NAME, &tp.Privileges[0].Luid)) // Enable the TCB Name privilege in the token. tp.PrivilegeCount = 1; tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; if (!AdjustTokenPrivileges(hDupToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), NULL, 0)) { DisplayError("AdjustTokenPrivileges"); ... } if (GetLastError() == ERROR_NOT_ALL_ASSIGNED) { DEBUG( "Token does not have the necessary privilege.\n"); } else { DEBUG( "No error reported from AdjustTokenPrivileges!\n"); } // Never errors here DEBUG(LM_INFO, "Attempting setting of sessionId to: %d\n", consoleSessionId ); if (!SetTokenInformation(hDupToken, TokenSessionId, &consoleSessionId, sizeof(DWORD))) *** ALWAYS FAILS WITH 1314 HERE *** All the debug output looks fine up until the SetTokenInformation call - I see session 0 is my current process session, and in my case, it's trying to set session 1 (the result of the WTSGetActiveConsoleSessionId). (Note that I'm logged into the W2K8 box via VNC, not RDC) So - a the questions: Is this approach valid, or are all service-initiated processes restricted to session 0 intentionally? Is there a better approach (short of "Launch on logon" and auto-logon for the servers?) Is there something wrong with this code, or a different way to create a process token where I can swap out the session id to indicate I want to spawn the process in a new session? I did try using LogonUser instead of OpenProcessToken, but that didn't work either. (I don't care if all spawned processes share the same non-zero session or not at this point.) Any help much appreciated - thanks!

• Why do I get a null pointer exception from TabWidget?

  - by rushinge

  I'm writing an android program in which I have an activity that uses tabs. The Activity public class UnitActivity extends TabActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TabHost tabHost = getTabHost(); TabSpec spec; Resources res = getResources(); LayoutInflater.from(this).inflate(R.layout.unit_view, tabHost.getTabContentView(), true); spec = tabHost.newTabSpec("controls"); spec.setIndicator("Control", res.getDrawable(R.drawable.ic_tab_equalizer)); spec.setContent(R.id.txtview); tabHost.addTab(spec); } } The XML referenced by R.layout.unit_view <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"> <TextView android:id="@+id/txtview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="bottom" android:text="nullpointer this!" /> </FrameLayout> </LinearLayout> </TabHost> As far as I can see I'm doing the same thing I see in the tabs1 api sample from the android sdk. I've tried "getLayoutInflator()" instead of "LayoutInflator.from(this)" with the same result. If I replace the LayoutInflater line with "setContentView(R.layout.unit_view)" my program doesn't crash with a null pointer exception but my content is completely blank and empty. I get the tab and that's it. I've checked to make sure R.layout.unit_view and tabHost are not null when it runs the LayoutInflater line and they seem to be fine. They're defenitely not null.

My actual program is more complex and has more than one tab but I simplified it down to this in an attempt to find out why it's crashing but it still crashes and I don't know why. If I don't use LayoutInflator my program doesn't crash but I don't get any content either, just tabs.

• PayPal IPN - having trouble accessing session data?

  - by Martin Bean

  Hello, all. I'm having issues with PayPal IPN integration where it seems I cannot get my solution to read session variables. Basically, in my shop module script, I store the customer's details as provided by PayPal to an orders table. However, I also wish to save products ordered in a transaction to a separate table linked by the order ID. However, it's the second part of the script that's not working, where I loop through the products in the session and then save them to the orders_products table. Is there a reason why the session data not being read? The code within shop.php is as follows: if ($paypal->validate_ipn()) { $name = $paypal->ipn_data['address_name']; $street_1 = $paypal->ipn_data['address_street']; $street_2 = ""; $city = $paypal->ipn_data['address_city']; $state = $paypal->ipn_data['address_state']; $zip = $paypal->ipn_data['address_zip']; $country = $paypal->ipn_data['address_country']; $txn_id = $paypal->ipn_data['txn_id']; $sql = "INSERT INTO orders (name, street_1, street_2, city, state, zip, country, txn_id) VALUES (:name, :street_1, :street_2, :city, :state, :zip, :country, :txn_id)"; $smt = $this->pdo->prepare($sql); $smt->bindParam(':name', $name, PDO::PARAM_STR); $smt->bindParam(':street_1', $street_1, PDO::PARAM_STR); $smt->bindParam(':street_2', $street_2, PDO::PARAM_STR); $smt->bindParam(':city', $city, PDO::PARAM_STR); $smt->bindParam(':state', $state, PDO::PARAM_STR); $smt->bindParam(':zip', $zip, PDO::PARAM_STR); $smt->bindParam(':country', $country, PDO::PARAM_STR); $smt->bindParam(':txn_id', $txn_id, PDO::PARAM_INT); $smt->execute(); // save products to orders relationship $order_id = $this->pdo->lastInsertId(); // $cart = $this->session->get('cart'); $cart = $this->session->get('cart'); foreach ($cart as $product_id => $item) { $quantity = $item['quantity']; $sql = "INSERT INTO orders_products (order_id, product_id, quantity) VALUES ('$order_id', '$product_id', '$quantity')"; $res = $this->pdo->query($sql); } $this->session->del('cart'); mail('[email protected]', 'IPN result', 'IPN was successful on wrestling-wear.com'); } else { mail('[email protected]', 'IPN result', 'IPN failed on wrestling-wear.com'); } And I'm using the PayPal IPN class for PHP as found here: http://www.micahcarrick.com/04-19-2005/php-paypal-ipn-integration-class.html, but the contents of the validate_ipn() method is as follows: public function validate_ipn() { $url_parsed = parse_url($this->paypal_url); $post_string = ''; foreach ($_POST as $field => $value) { $this->ipn_data[$field] = $value; $post_string.= $field.'='.urlencode(stripslashes($value)).'&'; } $post_string.= "cmd=_notify-validate"; // append IPN command // open the connection to PayPal $fp = fsockopen($url_parsed[host], "80", $err_num, $err_str, 30); if (!$fp) { // could not open the connection. If logging is on, the error message will be in the log $this->last_error = "fsockopen error no. $errnum: $errstr"; $this->log_ipn_results(false); return false; } else { // post the data back to PayPal fputs($fp, "POST $url_parsed[path] HTTP/1.1\r\n"); fputs($fp, "Host: $url_parsed[host]\r\n"); fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n"); fputs($fp, "Content-length: ".strlen($post_string)."\r\n"); fputs($fp, "Connection: close\r\n\r\n"); fputs($fp, $post_string . "\r\n\r\n"); // loop through the response from the server and append to variable while (!feof($fp)) { $this->ipn_response.= fgets($fp, 1024); } fclose($fp); // close connection } if (eregi("VERIFIED", $this->ipn_response)) { // valid IPN transaction $this->log_ipn_results(true); return true; } else { // invalid IPN transaction; check the log for details $this->last_error = 'IPN Validation Failed.'; $this->log_ipn_results(false); return false; } }

• Accessing a Service from within an XNA Content Pipeline Extension

  - by David Wallace

  I need to allow my content pipeline extension to use a pattern similar to a factory. I start with a dictionary type: public delegate T Mapper<T>(MapFactory<T> mf, XElement d); public class MapFactory<T> { Dictionary<string, Mapper<T>> map = new Dictionary<string, Mapper<T>>(); public void Add(string s, Mapper<T> m) { map.Add(s, m); } public T Get(XElement xe) { if (xe == null) throw new ArgumentNullException( "Invalid document"); var key = xe.Name.ToString(); if (!map.ContainsKey(key)) throw new ArgumentException( key + " is not a valid key."); return map[key](this, xe); } public IEnumerable<T> GetAll(XElement xe) { if (xe == null) throw new ArgumentNullException( "Invalid document"); foreach (var e in xe.Elements()) { var val = e.Name.ToString(); if (map.ContainsKey(val)) yield return map[val](this, e); } } } Here is one type of object I want to store: public partial class TestContent { // Test type public string title; // Once test if true public bool once; // Parameters public Dictionary<string, object> args; public TestContent() { title = string.Empty; args = new Dictionary<string, object>(); } public TestContent(XElement xe) { title = xe.Name.ToString(); args = new Dictionary<string, object>(); xe.ParseAttribute("once", once); } } XElement.ParseAttribute is an extension method that works as one might expect. It returns a boolean that is true if successful. The issue is that I have many different types of tests, each of which populates the object in a way unique to the specific test. The element name is the key to MapFactory's dictionary. This type of test, while atypical, illustrates my problem. public class LogicTest : TestBase { string opkey; List<TestBase> items; public override bool Test(BehaviorArgs args) { if (items == null) return false; if (items.Count == 0) return false; bool result = items[0].Test(args); for (int i = 1; i < items.Count; i++) { bool other = items[i].Test(args); switch (opkey) { case "And": result &= other; if (!result) return false; break; case "Or": result |= other; if (result) return true; break; case "Xor": result ^= other; break; case "Nand": result = !(result & other); break; case "Nor": result = !(result | other); break; default: result = false; break; } } return result; } public static TestContent Build(MapFactory<TestContent> mf, XElement xe) { var result = new TestContent(xe); string key = "Or"; xe.GetAttribute("op", key); result.args.Add("key", key); var names = mf.GetAll(xe).ToList(); if (names.Count() < 2) throw new ArgumentException( "LogicTest requires at least two entries."); result.args.Add("items", names); return result; } } My actual code is more involved as the factory has two dictionaries, one that turns an XElement into a content type to write and another used by the reader to create the actual game objects. I need to build these factories in code because they map strings to delegates. I have a service that contains several of these factories. The mission is to make these factory classes available to a content processor. Neither the processor itself nor the context it uses as a parameter have any known hooks to attach an IServiceProvider or equivalent. Any ideas?

• Trouble on setting SSL certificates for Virtual Hosts using Apache\Phusion Passenger in localhost

  - by user502052

  I am using Ruby on Rails 3 and I would like to make to work HTTPS connections on localhost. I am using: Apache v2 + Phusion Passenger Mac OS + Snow Leopard v10.6.6 My Ruby on Rails installation use the Typhoeus gem (it is possible to use the Ruby net\http library but the result doesn't change) to make HTTP requests over HTTPS. I created self-signed ca.key, pjtname.crt and pjtname.key as detailed on the Apple website. Notice: Following instruction from the Apple website, on running the openssl req -new -key server.key -out server.csr command (see the link) at this point Common Name (eg, YOUR name) []: (this is the important one) I entered *pjtname.com so that is valid for all sub_domain of that site. In my Apache httpd.conf I have two virtual hosts configured in this way: # Secure (SSL/TLS) connections #Include /private/etc/apache2/extra/httpd-ssl.conf # # Note: The following must must be present to support # starting without SSL on platforms with no /dev/random equivalent # but a statically compiled-in mod_ssl. # <IfModule ssl_module> SSLRandomSeed startup builtin SSLRandomSeed connect builtin </IfModule> Include /private/etc/apache2/other/*.conf # Passenger configuration LoadModule passenger_module /Users/<my_user_name>/.rvm/gems/ruby-1.9.2-p136/gems/passenger-3.0.2/ext/apache2/mod_passenger.so PassengerRoot /Users/<my_user_name>/.rvm/gems/ruby-1.9.2-p136/gems/passenger-3.0.2 PassengerRuby /Users/<my_user_name>/.rvm/wrappers/ruby-1.9.2-p136/ruby # Go ahead and accept connections for these vhosts # from non-SNI clients SSLStrictSNIVHostCheck off # Ensure that Apache listens on port 443 Listen 443 # Listen for virtual host requests on all IP addresses NameVirtualHost *:80 NameVirtualHost *:443 # # PJTNAME.COM and subdomains SETTING # <VirtualHost *:443> # Because this virtual host is defined first, it will # be used as the default if the hostname is not received # in the SSL handshake, e.g. if the browser doesn't support # SNI.

All this means that something is wrong. So, what I have to do to avoid the "Peer certificate cannot be authenticated with known CA certificates" warning and make the HTTPS request to work? Where is\are the error\errors (I think in the Apache configuration, but where?!)? P.S.: if you need some more info, let me know.

• How do I drag and drop between two listboxes in XUL?

  - by pc1oad1etter

  I am trying to implement drag and drop between two listboxes. I have a few problems 1) I am not detecting any drag events of any kind from the source list box/ I do not seem to be able to drag from it 2) I can drag from my desktop to the target listbox and I am able to detect 'dragenter' 'dragover' and 'dragexit' events. I am noticing that the event parameter is undefined in my 'dragenter' callback - is this a problem? 3) I cannot figure out how to complete the drag and drop operation. From https://developer.mozilla.org/En/DragDrop/Drag_Operations#Performing_... "If the mouse was released over an element that is a valid drop target, that is, one that cancelled the last dragenter or dragover event, then the drop will be successful, and a drop event will fire at the target. Otherwise, the drag operation is cancelled and no drop event is fired." This seems to be referring to a 'drop' event, though there is not one listed at https://developer.mozilla.org/en/XUL/Events . I can't seem to detect the end of the drag in order to call one of the example 'doDrop()' functions that I find on MDC. My example, so far: http://pastebin.mozilla.org/713676 <?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <window xmlns="http://www.mozilla.org/keymaster/gatekeeper/ there.is.only.xul" onload="initialize();"> <vbox> <hbox> <vbox> <description>List1</description> <listbox id="source" draggable="true"> <listitem label="1"/> <listitem label="3"/> <listitem label="4"/> <listitem label="5"/> </listbox> </vbox> <vbox> <description>List2</description> <listbox id="target" ondragenter="onDragEnter();"> <listitem label="2"/> </listbox> </vbox> </hbox> </vbox> <script type="application/x-javascript"> <![CDATA[ function initialize(){ jsdump('adding events'); var origin = document.getElementById("source"); origin.addEventListener("drag", onDrag, false); origin.addEventListener("dragdrop", onDragDrop, false); origin.addEventListener("dragend", onDragEnd, false); origin.addEventListener("dragstart", onDragStart, false); var target = document.getElementById("target"); target.addEventListener("dragenter", onDragEnter, false); target.addEventListener("dragover", onDragOver, false); target.addEventListener("dragexit", onDragExit, false); target.addEventListener("drop", onDrop, false); target.addEventListener("drag", onDrag, false); target.addEventListener("dragdrop", onDragDrop, false); } function onDrag(){ jsdump('onDrag'); } function onDragDrop(){ jsdump('onDragDrop'); } function onDragStart(){ jsdump('onDragStart'); } function onDragEnd(){ jsdump('onDragEnd'); } function onDragEnter(event){ //debugger; if(event){ jsdump('onDragEnter event.preventDefault()'); event.preventDefault(); }else{ jsdump("event undefined in onDragEnter"); } } function onDragExit(){ jsdump('onDragExit'); } function onDragOver(event){ //debugger; if(event){ //jsdump('onDragOver event.preventDefault()'); event.preventDefault(); }else{ jsdump("event undefined in onDragOver"); } } function onDrop(event){ jsdump('onDrop'); var data = event.dataTransfer.getData("text/plain"); event.target.textContent = data; event.preventDefault(); } function jsdump(str) { Components.classes['[email protected]/consoleservice;1'] .getService(Components.interfaces.nsIConsoleService) .logStringMessage(str); } ]]> </script> </window>

• Of these 3 methods for reading linked lists from shared memory, why is the 3rd fastest?

  - by Joseph Garvin

  I have a 'server' program that updates many linked lists in shared memory in response to external events. I want client programs to notice an update on any of the lists as quickly as possible (lowest latency). The server marks a linked list's node's state_ as FILLED once its data is filled in and its next pointer has been set to a valid location. Until then, its state_ is NOT_FILLED_YET. I am using memory barriers to make sure that clients don't see the state_ as FILLED before the data within is actually ready (and it seems to work, I never see corrupt data). Also, state_ is volatile to be sure the compiler doesn't lift the client's checking of it out of loops. Keeping the server code exactly the same, I've come up with 3 different methods for the client to scan the linked lists for changes. The question is: Why is the 3rd method fastest? Method 1: Round robin over all the linked lists (called 'channels') continuously, looking to see if any nodes have changed to 'FILLED': void method_one() { std::vector<Data*> channel_cursors; for(ChannelList::iterator i = channel_list.begin(); i != channel_list.end(); ++i) { Data* current_item = static_cast<Data*>(i->get(segment)->tail_.get(segment)); channel_cursors.push_back(current_item); } while(true) { for(std::size_t i = 0; i < channel_list.size(); ++i) { Data* current_item = channel_cursors[i]; ACQUIRE_MEMORY_BARRIER; if(current_item->state_ == NOT_FILLED_YET) { continue; } log_latency(current_item->tv_sec_, current_item->tv_usec_); channel_cursors[i] = static_cast<Data*>(current_item->next_.get(segment)); } } } Method 1 gave very low latency when then number of channels was small. But when the number of channels grew (250K+) it became very slow because of looping over all the channels. So I tried... Method 2: Give each linked list an ID. Keep a separate 'update list' to the side. Every time one of the linked lists is updated, push its ID on to the update list. Now we just need to monitor the single update list, and check the IDs we get from it. void method_two() { std::vector<Data*> channel_cursors; for(ChannelList::iterator i = channel_list.begin(); i != channel_list.end(); ++i) { Data* current_item = static_cast<Data*>(i->get(segment)->tail_.get(segment)); channel_cursors.push_back(current_item); } UpdateID* update_cursor = static_cast<UpdateID*>(update_channel.tail_.get(segment)); while(true) { if(update_cursor->state_ == NOT_FILLED_YET) { continue; } ::uint32_t update_id = update_cursor->list_id_; Data* current_item = channel_cursors[update_id]; if(current_item->state_ == NOT_FILLED_YET) { std::cerr << "This should never print." << std::endl; // it doesn't continue; } log_latency(current_item->tv_sec_, current_item->tv_usec_); channel_cursors[update_id] = static_cast<Data*>(current_item->next_.get(segment)); update_cursor = static_cast<UpdateID*>(update_cursor->next_.get(segment)); } } Method 2 gave TERRIBLE latency. Whereas Method 1 might give under 10us latency, Method 2 would inexplicably often given 8ms latency! Using gettimeofday it appears that the change in update_cursor-state_ was very slow to propogate from the server's view to the client's (I'm on a multicore box, so I assume the delay is due to cache). So I tried a hybrid approach... Method 3: Keep the update list. But loop over all the channels continuously, and within each iteration check if the update list has updated. If it has, go with the number pushed onto it. If it hasn't, check the channel we've currently iterated to. void method_three() { std::vector<Data*> channel_cursors; for(ChannelList::iterator i = channel_list.begin(); i != channel_list.end(); ++i) { Data* current_item = static_cast<Data*>(i->get(segment)->tail_.get(segment)); channel_cursors.push_back(current_item); } UpdateID* update_cursor = static_cast<UpdateID*>(update_channel.tail_.get(segment)); while(true) { for(std::size_t i = 0; i < channel_list.size(); ++i) { std::size_t idx = i; ACQUIRE_MEMORY_BARRIER; if(update_cursor->state_ != NOT_FILLED_YET) { //std::cerr << "Found via update" << std::endl; i--; idx = update_cursor->list_id_; update_cursor = static_cast<UpdateID*>(update_cursor->next_.get(segment)); } Data* current_item = channel_cursors[idx]; ACQUIRE_MEMORY_BARRIER; if(current_item->state_ == NOT_FILLED_YET) { continue; } found_an_update = true; log_latency(current_item->tv_sec_, current_item->tv_usec_); channel_cursors[idx] = static_cast<Data*>(current_item->next_.get(segment)); } } } The latency of this method was as good as Method 1, but scaled to large numbers of channels. The problem is, I have no clue why. Just to throw a wrench in things: if I uncomment the 'found via update' part, it prints between EVERY LATENCY LOG MESSAGE. Which means things are only ever found on the update list! So I don't understand how this method can be faster than method 2. The full, compilable code (requires GCC and boost-1.41) that generates random strings as test data is at: http://pastebin.com/e3HuL0nr

• Users being forced to re-login randomly, before session and auth ticket timeout values are reached

  - by Don

  I'm having reports and complaints from my user that they will be using a screen and get kicked back to the login screen immediately on their next request. It doesn't happen all the time but randomly. After looking at the Web server the error that shows up in the application event log is: Event code: 4005 Event message: Forms authentication failed for the request. Reason: The ticket supplied has expired. Everything that I read starts out with people asking about web gardens or load balancing. We are not using either of those. We're a single Windows 2003 (32-bit OS, 64-bit hardware) Server with IIS6. This is the only website on this server too. This behavior does not generate any application exceptions or visible issues to the user. They just get booted back to the login screen and are forced to login. As you can imagine this is extremely annoying and counter-productive for our users. Here's what I have set in my web.config for the application in the root: <authentication mode="Forms"> <forms name=".TcaNet" protection="All" timeout="40" loginUrl="~/Login.aspx" defaultUrl="~/MyHome.aspx" path="/" slidingExpiration="true" requireSSL="false" /> </authentication> I have also read that if you have some locations setup that no longer exist or are bogus you could have issues. My path attributes are all valid directories so that shouldn't be the problem: <location path="js"> <system.web> <authorization> <allow users="*" /> </authorization> </system.web> </location> <location path="images"> <system.web> <authorization> <allow users="*" /> </authorization> </system.web> </location> <location path="anon"> <system.web> <authorization> <allow users="*" /> </authorization> </system.web> </location> <location path="App_Themes"> <system.web> <authorization> <allow users="*" /> </authorization> </system.web> </location> <location path="NonSSL"> <system.web> <authorization> <allow users="*" /> </authorization> </system.web> </location> The only thing I'm not clear on is if my timeout value in the forms property for the auth ticket has to be the same as my session timeout value (defined in the app's configuration in IIS). I've read some things that say you should have the authentication timeout shorter (40) than the session timeout (45) to avoid possible complications. Either way we have users that get kicked to the login screen a minute or two after their last action. So the session definitely should not be expiring. Update 2/23/09: I've since set the session timeout and authentication ticket timeout values to both be 45 and the problem still seems to be happening. The only other web.config in the application is in 1 virtual directory that hosts Community Server. That web.config's authentication settings are as follows: <authentication mode="Forms"> <forms name=".TcaNet" protection="All" timeout="40" loginUrl="~/Login.aspx" defaultUrl="~/MyHome.aspx" path="/" slidingExpiration="true" requireSSL="true" /> </authentication> And while I don't believe it applies unless you're in a web garden, I have both of the machine key values set in both web.config files to be the same (removed for convenience): <machineKey validationKey="<MYVALIDATIONKEYHERE>" decryptionKey="<MYDECRYPTIONKEYHERE>" validation="SHA1" /> <machineKey validationKey="<MYVALIDATIONKEYHERE>" decryptionKey="<MYDECRYPTIONKEYHERE>" validation="SHA1"/> Any help with this would be greatly appreciated. This seems to be one of those problems that yields a ton of Google results, none of which seem to be fitting into my situation so far.

• Why does this XML validation via XSD fail in libxml2 (but succeed in xmllint) and how do I fix it?

• Why can't my main class see the array in my calender class

  - by Rocky Celltick Eadie

  This is a homework problem. I'm already 5 days late and can't figure out what I'm doing wrong.. this is my 1st semester in Java and my first post on this site Here is the assignment.. Create a class called Calendar. The class should contain a variable called events that is a String array. The array should be created to hold 5 elements. Use a constant value to specify the array size. Do not hard code the array size. Initialize the array in the class constructor so that each element contains the string “ – No event planned – “. The class should contain a method called CreateEvent. This method should accept a String argument that contains a one-word user event and an integer argument that represents the day of the week. Monday should be represented by the number 1 and Friday should be represented by the number 5. Populate the events array with the event info passed into the method. Although the user will input one-word events, each event string should prepend the following string to each event: event_dayAppoinment: (where event_day is the day of the week) For example, if the user enters 1 and “doctor” , the first array element should read: Monday Appointment: doctor If the user enters 2 and “PTA” , the second array element should read: Tuesday Appointment: PTA Write a driver program (in a separate class) that creates and calls your Calendar class. Then use a loop to gather user input. Ask for the day (as an integer) and then ask for the event (as a one word string). Pass the integer and string to the Calendar object’s CreateEvent method. The user should be able enter 0 – 5 events. If the user enters -1, the loop should exit and your application should print out all the events in a tabular format. Your program should not allow the user to enter invalid values for the day of the week. Any input other than 1 – 5 or -1 for the day of the week would be considered invalid. Notes: When obtaining an integer from the user, you will need to use the nextInt() method on your Scanner object. When obtaining a string from a user, you will need to use the next() method on your Scanner object. Here is my code so far.. //DRIVER CLASS /** * * @author Rocky */ //imports scanner import java.util.Scanner; //begin class driver public class driver { /** * @paramargs the command line arguments */ //begin main method public static void main(String[] args) { //initiates scanner Scanner userInput = new Scanner (System.in); //declare variables int dayOfWeek; String userEvent; //creates object for calender class calendercalenderObject = new calender(); //user prompt System.out.println("Enter day of week for your event in the following format:"); System.out.println("Enter 1 for Monday"); System.out.println("Enter 2 for Tuesday"); System.out.println("Enter 3 for Wednsday"); System.out.println("Enter 4 for Thursday"); System.out.println("Enter 5 for Friday"); System.out.println("Enter -1 to quit"); //collect user input dayOfWeek = userInput.nextInt(); //user prompt System.out.println("Please type in the name of your event"); //collect user input userEvent = userInput.next(); //begin while loop while (dayOfWeek != -1) { //test for valid day of week if ((dayOfWeek>=1) && (dayOfWeek<=5)){ //calls createEvent method in calender class and passes 2 variables calenderObject.createEvent(userEvent,dayOfWeek); } else { //error message System.out.println("You have entered an invalid number"); //user prompts System.out.println("Press -1 to quit or enter another day"); System.out.println("Enter 1 for Monday"); System.out.println("Enter 2 for Tuesday"); System.out.println("Enter 3 for Wednsday"); System.out.println("Enter 4 for Thursday"); System.out.println("Enter 5 for Friday"); System.out.println("Enter -1 to quit"); //collect user input dayOfWeek = userInput.nextInt(); //end data validity test } //end while loop } //prints array to screen int i=0; for (i=0;i<events.length;i++){ System.out.println(events[i]); } //end main method } } /** * * @author Rocky */ //imports scanner import java.util.Scanner; //begin calender class public class calender { //creates events array String[] events = new String[5]; //begin calender class constructor public calender() { //Initializes array String[] events = {"-No event planned-","-No event planned-","-No event planned-","-No event planned-","-No event planned-"}; //end calender class constructor } //begin createEvent method public String[] createEvent (String userEvent, int dayOfWeek){ //Start switch test switch (dayOfWeek){ case 1: events[0] = ("Monday Appoinment:") + userEvent; break; case 2: events[1] = ("Tuesday Appoinment:") + userEvent; break; case 3: events[2] = ("WednsdayAppoinment:") + userEvent; break; case 4: events[3] = ("Thursday Appoinment:") + userEvent; break; case 5: events[4] = ("Friday Appoinment:") + userEvent; break; default: break; //End switch test } //returns events array return events; //end create event method } //end calender class }
