• Win32_Product InstallLocation (error)

  - by andrew

  in C#, i'm trying to get some properties from the instances of Win32_Product, but i seem to have an error saying "Object reference not set to an instance of an object." here's the code: class Package { public string productName; public string installDate; public string installLocation; } class InstalledPackages { public static List<Package> get() { List<Package> packages = new List<Package>(); string query = "SELECT * FROM Win32_Product"; ManagementScope oMs = new ManagementScope(); ObjectQuery oQuery = new ObjectQuery(query); ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(oMs, oQuery); ManagementObjectCollection installedPackages = oSearcher.Get(); foreach (ManagementObject package in installedPackages) { Package p = new Package(); p.productName = package["Name"].ToString(); p.installLocation = package["InstallLocation"].ToString(); p.installDate = package["InstallDate"].ToString(); packages.Add(p); } return packages; } } the exception appears when it gets to p.installLocation = package["InstallLocation"].ToString(); also, i get one if i try to do p.installLocation = package["InstallDate2"].ToString(); if i'm asking for InstallDate it works. (i'm using Windows 7 Ultimate x64)

• Error while setting UserAcces permission for WebForms?

  - by ksg

  I've created a class named BaseClass.cs and I've written a function in its constructor. Here's how it looks public class BasePage:Page { public BasePage() { setUserPermission(); } private void setUserPermission() { String strPathAndQuery = HttpContext.Current.Request.Url.PathAndQuery; string strulr = strPathAndQuery.Replace("/SGERP/", "../"); Session["Url"] = strulr; GEN_FORMS clsForm = new GEN_FORMS(); clsForm.Form_Logical_Name = Session["Url"].ToString(); clsForm.User_ID = Convert.ToInt32(Session["User_ID"]); DataSet dsPermission = clsForm.RETREIVE_BUTTON_PERMISSIONS(); if (dsPermission.Tables.Count > 0) { if (dsPermission.Tables[1].Rows.Count > 0) { Can_Add = Convert.ToBoolean(dsPermission.Tables[1].Rows[0]["Can_Add"].ToString()); Can_Delete = Convert.ToBoolean(dsPermission.Tables[1].Rows[0]["Can_Delete"].ToString()); Can_Edit = Convert.ToBoolean(dsPermission.Tables[1].Rows[0]["Can_Edit"].ToString()); Can_Print = Convert.ToBoolean(dsPermission.Tables[1].Rows[0]["Can_Print"].ToString()); Can_View = Convert.ToBoolean(dsPermission.Tables[1].Rows[0]["Can_Print"].ToString()); } } } } I've inherited this class on my webform so that when the page loads, the setUserPermission function is executed. My webpage looks like this public partial class Setting_CompanyDetails : BasePage My problem is that I cannot access Session["Url"] in my BasePage. I'm getting the following error Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration. How can I solve this issue? Is this the right way to set UserPermission access?

• XStream noclassdeffound error

  - by Jimmy

  I am attempting to run Xstream in a netbeans proof of concept project. I have the following code. XStream xstream = new XStream(); FileOutputStream fis = new FileOutputStream("Test.xml"); xstream.toXML(company, fis); The program is crashing on the first line of code with the following error. Exception in thread "main" java.lang.NoClassDefFoundError: org/xmlpull/v1/XmlPullParserException at com.thoughtworks.xstream.XStream.<init>(XStream.java:336) at Parser.XParser.Parse(XParser.java:24) at rejaxbtest.REJAXBTest.main(REJAXBTest.java:39) Caused by: java.lang.ClassNotFoundException: org.xmlpull.v1.XmlPullParserException at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) ... 3 more Java Result: 1 I have seen one other thread with this problem, but the answer that was given was put the jar in the project lib directory, but netbeans has already correctly finished that task. Any other possible thing that would cause java not to recognize the Xstream class at runtime even though it is fine at compile time? Thanks Jimmy

• Error with `Thread.Sleep` during automatic testing on TeamCity 5

  - by yeyeyerman

  Hello, I'm having some problems executing the tests of the application I'm developing. All the tests execute normally with ReSharper and in NCover. However, the execution of one of these tests in TeamCity is generating an error. This test initializes two objects, the object under test and a simulator of a real object. Both objects will communicate throug a serial link in a representation of the real scenario. ObjectSimulator r_simulator = new ObjectSimulator(...); ObjectDriver r_driver = new ObjectDriver(...); Assert.IsTrue(r_driver.Connect() == ErrorCode.Success); The simulator just do the following in the constructor public class ObjectSimulator { ... public ObjectSimulator() { // serial port configuration m_port = new SerialPort(); m_port.DataReceived += DataReceivedEvent; } ... } The main object has two threads. The main thread of the application and a timer to refresh a watchdog timer in the real object. public ErrorCode Connect() { ... StartSynchroTimer(); Thread.Sleep(4); // to check if the timer is working properly ... } The problem seems to be comming from the Thread.Sleep() call, as when I remove it everything works. The ObjectSimulator somehow doesn't execute the DataReceived event callback. How can I resolve this issue?

• How to deal with delegate method calling back the object who send the message ?

  - by olipion

  I have two object: @protocol ObjectADelegate - (void)objectAfirst:(ObjectA *)obj; - (void)objectAsecond:(ObjectA *)obj; @end @interface ObjectA : NSObject { id<ObjectADelegate> delegate; - (void)callSecond { [self.delegate objectAsecond:self]; } @end @interface ObjectB : NSObject <ObjectADelegate>{ ObjectA *myObjectA; } @implementation ObjectB - (void)objectAfirst:(ObjectA *)obj { // First is finished, do second [obj callSecond]; } - (void)objectASecond:(ObjectA *)obj { // Do my stuff } @end As you can see in the code, when ObjectA send the message objectAfirst to its delegate, objectb use again objectA methods that result in objecta calling back objectb. It means that what first fire objectAfirst is not finished but objectA send the objectAsecond message. Could it be a problem ? Any way to let delay message handling in objectB ? for example, something like using [obj performSelector:@selector(callSecond) afterDelay:0.01]; instead of [obj callSecond]; ?

• Php header('Location") error

  - by Umeed

  I'm having some difficulty with my php coding. I have 3 files, add.php, lib.php, and view.php I created a simple form, and when the user clicks submit, it should direct them to the view.php where it will display the database. Now I'm having a couple issues I can't seem to resolve. when the user clicks submit and the fields are blank or there is an error no entry should be made into the view page (or database)...however when I click submit a blank entry is made into the database. ALSO if i click "enter product" from the top menu bar anytime I click it, it causes a blank entry into the database. I can't figure out why that's happening. My next issue is with the header('Location') and my browser says: "Warning: Cannot modify header information - headers already sent by (output started at lib.php:13) in add.php on line 16" However if I click submit on my form it goes away. Here is the code for the pages: http://ideone.com/Vvz8x I truly apologize if the code is really messy. Any help / advice / solution is greatly appreciated thank you. And yes this was an assignment---it was due last week but since I couldn't finish it, it's not worth any marks anymore.

• bubble sort logic error

  - by Arianule

  I was trying a basic sorting exercise and I was hoping I could receive some help with what is probably a basic logic error. int[] numbers = new int[] { 2, 5, 11, 38, 24, 6, 9, 0, 83, 7 }; for (int loop = 0; loop < numbers.Length; loop++) { Console.WriteLine(numbers[loop]); } Console.WriteLine("Performing a bubble sort"); bool flag = false; do { for (int loop = 0; loop < numbers.Length - 1; loop++) { if (numbers[loop] > numbers[loop + 1]) { int temporary = numbers[loop]; numbers[loop] = numbers[loop + 1]; numbers[loop + 1] = temporary; flag = true; } } } while (flag == false); for (int loop = 0; loop < numbers.Length; loop++) { Console.WriteLine(numbers[loop]); } kind regards arianule

• Complex Forms Generating Error

  - by user1648020

  I am working on an application that allows students to create a catalog of courses they are taking for a semester. I have created models for user; course; subject and category. Users can have many courses. Each course can have many subjects and categories. The tables for courses, subjects and categories include the following: Catalog: user_id; subject_id, category_id and course_id Courses: user_id; coursedetail_id Coursedetail: name; description Subject: name; description Category: name; description The idea is that an Admin can create a list of courses; subjects and categories and that the user can select the courses they want to add to their catalog. I have seperated courses and coursedetails because I envision that the coursedetails will grow overtime and the courses table will allow me to join the user_id and cousres details to rreport on if necessary. I attempted to follow Ryan's railscast on Complex Forms thinking that that I should use a complex form and has many relationship to get things working -- but I get an error in the catalog controller - cannot locate catalog_id which I know is in the table. I am now not sure if complex forms is the way to go or I should be looking at another direction to get the appropriate form in place. Any assistance would be appreciated.

• Maven2 multi-module ejb 3.1 project - deployment error

  - by gerry

  The problem is taht I get the following error qhile deploying my project to Glassfish: java.lang.RuntimeException: Unable to load EJB module. DeploymentContext does not contain any EJB Check archive to ensure correct packaging But, let us start on how the project structure looks like in Maven2... I've build the following scenario: MultiModuleJavaEEProject - parent module - model --- packaged as jar - ejb1 ---- packaged as ebj - ejb2 ---- packaged as ebj - web ---- packaged as war So model,

package testing.ejb1; import javax.ejb.Stateless; import testing.model.Data; @Stateless public class DataService { private Data data; public DataService(){ data = new Data(); data.setData("Hello World!"); } public String getDataText(){ return data.getData(); } } As well as the ejb2 is only a stateless ejb: package testing.ejb2; import javax.ejb.EJB; import javax.ejb.Stateless; import testing.ejb1.DataService; @Stateless public class Service { @EJB DataService service; public Service(){ } public String getText(){ return service.getDataText(); } } And the web module contains only a

javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import testing.ejb2.Service; public class SimpleServlet extends HttpServlet { @EJB Service service; public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { PrintWriter out = response.getWriter(); out.println( "SimpleServlet Executed" ); out.println( "Text: "+service.getText() ); out.flush(); out.close(); } } And the web.xml file in the web module looks like: <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

files are set up by me. There is no ejb-jar.xml in any ejb files, because I'm using EJB 3.1. So I think ejb-jar.xml descriptors are optional. I this right? But the problem is, the already mentioned error: java.lang.RuntimeException: Unable to load EJB module. DeploymentContext does not contain any EJB Check archive to ensure correct packaging Can anybody help?

• SOAP PHP Parsing Error?

  - by Josh

  I'm communicating with a SOAP service created with EJB -- it intermittently fails, and I've found a case where I can reliably reproduce. I'm getting a funky ass SOAP fault that says "looks like we got not XML," however, when retrieving the last response I get what is listed below (and what looks like valid XML to me). Any thoughts? Soap Fault: object(SoapFault)#2 (9) { ["message:protected"]=> string(33) "looks like we got no XML document" ["string:private"]=> string(0) "" ["code:protected"]=> int(0) ["file:protected"]=> string(40) "/Users/josh/Sites/blahblahblah/test-update.php" ["line:protected"]=> int(26) ["trace:private"]=> array(2) { [0]=> array(4) { ["function"]=> string(6) "__call" ["class"]=> string(10) "SoapClient" ["type"]=> string(2) "->" ["args"]=> array(2) { [0]=> string(24) "UpdateApplicationProfile" [1]=> array(1) { [0]=> array(2) { ["suid"]=> string(36) "62eb56ee-45de-4971-9234-54d72bbcd0e4" ["appid"]=> string(36) "6be2f269-4ddc-48af-9d47-30b7cf3d0499" } } } } [1]=> array(6) { ["file"]=> string(40) "/Users/josh/Sites/blahblahblah/test-update.php" ["line"]=> int(26) ["function"]=> string(24) "UpdateApplicationProfile" ["class"]=> string(10) "SoapClient" ["type"]=> string(2) "->" ["args"]=> array(1) { [0]=> array(2) { ["suid"]=> string(36) "62eb56ee-45de-4971-9234-54d72bbcd0e4" ["appid"]=> string(36) "6be2f269-4ddc-48af-9d47-30b7cf3d0499" } } } } ["faultstring"]=> string(33) "looks like we got no XML document" ["faultcode"]=> string(6) "Client" ["faultcodens"]=> string(41) "http://schemas.xmlsoap.org/soap/envelope/" } And the actual raw XML response using client-__getLastResponse(): <env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'> <env:Header> </env:Header> <env:Body> <ns2:UpdateApplicationProfileResponse xmlns:ns2="blahblahblah"> <paramname>status</paramname> <paramname>location</paramname> <paramname>timezone</paramname> <paramname>homepage</paramname> <paramname>nickname</paramname> <paramname>firstName</paramname> <paramname>languages</paramname> <paramname>color</paramname> <paramname>lastName</paramname> <paramname>gender</paramname> <paramvalue></paramvalue> <paramvalue></paramvalue> <paramvalue></paramvalue> <paramvalue></paramvalue> <paramvalue>XXX XXX</paramvalue> <paramvalue>XXX</paramvalue> <paramvalue></paramvalue> <paramvalue>CA0008</paramvalue> <paramvalue>XXX</paramvalue> <paramvalue></paramvalue> </ns2:UpdateApplicationProfileResponse> </env:Body> </env:Envelope>

• Error using Session in IIS7

  - by flashnik

  After deployment of my website to IIS I'm getting a following error message when trying to access session: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration. I access it in Page_Load or PreRender events (I tried both versions). With VS Dev Server it works without a problem. I tried both InProc an SessionState storage, 1 and multiple woker processes. I added a enableSessionState = "true" to my webpage explicitly. Here is part of web.config: <system.web> <globalization culture="ru-RU" uiCulture="ru-RU" /> <compilation debug="true" defaultLanguage="c#"> <assemblies> <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> <add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> <add assembly="System.Web.Extensions.Design, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" /> <add assembly="System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> </assemblies> </compilation> <pages enableEventValidation="false" enableSessionState="true"> <controls> <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </controls> </pages> <httpHandlers> <remove verb="*" path="*.asmx" /> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false" /> </httpHandlers> <httpModules> <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add name="SearchUrlRewriter" type="Synonymizer.SearchUrlRewriter, Synonymizer, Version=1.0.0.0, Culture=neutral" /> <add name="Session" type="System.Web.SessionStateModule" /> </httpModules> <sessionState cookieless="UseCookies" cookieName="My_SessionId" mode="InProc" stateNetworkTimeout="5" /> <customErrors mode="Off" /> </system.web> What else do I need to do to make it work??

• Entity Framework Generic Repository Error

  - by Jeff Ancel

  I am trying to create a very generic generics repository for my Entity Framework repository that has the basic CRUD statements and uses an Interface. I have hit a brick wall head first and been knocked over. Here is my code, written in a console application, using a Entity Framework Model, with a table named Hurl. Simply trying to pull back the object by its ID. Here is the full application code. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data.Objects; using System.Linq.Expressions; using System.Reflection; using System.Data.Objects.DataClasses; namespace GenericsPlay { class Program { static void Main(string[] args) { var hs = new HurlRepository(new hurladminEntity()); var hurl = hs.Load<Hurl>(h => h.Id == 1); Console.Write(hurl.ShortUrl); Console.ReadLine(); } } public interface IHurlRepository { T Load<T>(Expression<Func<T, bool>> expression); } public class HurlRepository : IHurlRepository, IDisposable { private ObjectContext _objectContext; public HurlRepository(ObjectContext objectContext) { _objectContext = objectContext; } public ObjectContext ObjectContext { get { return _objectContext; } } private Type GetBaseType(Type type) { Type baseType = type.BaseType; if (baseType != null && baseType != typeof(EntityObject)) { return GetBaseType(type.BaseType); } return type; } private bool HasBaseType(Type type, out Type baseType) { Type originalType = type.GetType(); baseType = GetBaseType(type); return baseType != originalType; } public IQueryable<T> GetQuery<T>() { Type baseType; if (HasBaseType(typeof(T), out baseType)) { return this.ObjectContext.CreateQuery<T>("[" + baseType.Name.ToString() + "]").OfType<T>(); } else { return this.ObjectContext.CreateQuery<T>("[" + typeof(T).Name.ToString() + "]"); } } public T Load<T>(Expression<Func<T, bool>> whereCondition) { return this.GetQuery<T>().Where(whereCondition).First(); } public void Dispose() { if (_objectContext != null) { _objectContext.Dispose(); } } } } Here is the error that I am getting: System.Data.EntitySqlException was unhandled Message="'Hurl' could not be resolved in the current scope or context. Make sure that all referenced variables are in scope, that required schemas are loaded, and that namespaces are referenced correctly., near escaped identifier, line 3, column 1."

• Service Broker, not ETL

  - by jamiet

  I have been very quiet on this blog of late and one reason for that is I have been very busy on a client project that I would like to talk about a little here. The client that I have been working for has a website that runs on a distributed architecture utilising a messaging infrastructure for communication between different endpoints. My brief was to build a system that could consume these messages and produce analytical information in near-real-time. More specifically I basically had to deliver a data warehouse however it was the real-time aspect of the project that really intrigued me. This real-time requirement meant that using an Extract transformation, Load (ETL) tool was out of the question and so I had no choice but to write T-SQL code (i.e. stored-procedures) to process the incoming messages and load the data into the data warehouse. This concerned me though – I had no way to control the rate at which data would arrive into the system yet we were going to have end-users querying the system at the same time that those messages were arriving; the potential for contention in such a scenario was pretty high and and was something I wanted to minimise as much as possible. Moreover I did not want the processing of data inside the data warehouse to have any impact on the customer-facing website. As you have probably guessed from the title of this blog post this is where Service Broker stepped in! For those that have not heard of it Service Broker is a queuing technology that has been built into SQL Server since SQL Server 2005. It provides a number of features however the one that was of interest to me was the fact that it facilitates asynchronous data processing which, in layman’s terms, means the ability to process some data without requiring the system that supplied the data having to wait for the response. That was a crucial feature because on this project the customer-facing website (in effect an OLTP system) would be calling one of our stored procedures with each message – we did not want to cause the OLTP system to wait on us every time we processed one of those messages. This asynchronous nature also helps to alleviate the contention problem because the asynchronous processing activity is handled just like any other task in the database engine and hence can wait on another task (such as an end-user query). Service Broker it was then! The stored procedure called by the OLTP system would simply put the message onto a queue and we would use a feature called activation to pick each message off the queue in turn and process it into the warehouse. At the time of writing the system is not yet up to full capacity but so far everything seems to be working OK (touch wood) and crucially our users are seeing data in near-real-time. By near-real-time I am talking about latencies of a few minutes at most and to someone like me who is used to building systems that have overnight latencies that is a huge step forward! So then, am I advocating that you all go out and dump your ETL tools? Of course not, no! What this project has taught me though is that in certain scenarios there may be better ways to implement a data warehouse system then the traditional “load data in overnight” approach that we are all used to. Moreover I have really enjoyed getting to grips with a new technology and even if you don’t want to use Service Broker you might want to consider asynchronous messaging architectures for your BI/data warehousing solutions in the future. This has been a very high level overview of my use of Service Broker and I have deliberately left out much of the minutiae of what has been a very challenging implementation. Nonetheless I hope I have caused you to reflect upon your own approaches to BI and question whether other approaches may be more tenable. All comments and questions gratefully received! Lastly, if you have never used Service Broker before and want to kick the tyres I have provided below a very simple “Service Broker Hello World” script that will create all of the objects required to facilitate Service Broker communications and then send the message “Hello World” from one place to anther! This doesn’t represent a “proper” implementation per se because it doesn’t close down down conversation objects (which you should always do in a real-world scenario) but its enough to demonstrate the capabilities! @Jamiet ----------------------------------------------------------------------------------------------- /*This is a basic Service Broker Hello World app. Have fun! -Jamie */ USE MASTER GO CREATE DATABASE SBTest GO --Turn Service Broker on! ALTER DATABASE SBTest SET ENABLE_BROKER GO USE SBTest GO -- 1) we need to create a message type. Note that our message type is -- very simple and allowed any type of content CREATE MESSAGE TYPE HelloMessage VALIDATION = NONE GO -- 2) Once the message type has been created, we need to create a contract -- that specifies who can send what types of messages CREATE CONTRACT HelloContract (HelloMessage SENT BY INITIATOR) GO --We can query the metadata of the objects we just created SELECT * FROM   sys.service_message_types WHERE name = 'HelloMessage'; SELECT * FROM   sys.service_contracts WHERE name = 'HelloContract'; SELECT * FROM   sys.service_contract_message_usages WHERE  service_contract_id IN (SELECT service_contract_id FROM sys.service_contracts WHERE name = 'HelloContract') AND        message_type_id IN (SELECT message_type_id FROM sys.service_message_types WHERE name = 'HelloMessage'); -- 3) The communication is between two endpoints.

• External USB attached drive works in Windows XP but not in Windows 7. How to fix?

  - by irrational John

  Earlier this week I purchased this "N52300 EZQuest Pro" external hard drive enclosure from here. I can connect the enclosure using USB 2.0 and access the files in both NTFS partitions on the MBR partitioned drive when I use either Windows XP (SP3) or Mac OS X 10.6. So it works as expected in XP & Snow Leopard. However, the enclosure does not work in Windows 7 (Home Premium) either 64-bit or 32-bit or in Ubuntu 10.04 (kernel 2.6.32-23-generic). I'm thinking this must be a Windows 7 driver problem because the enclosure works in XP & Snow Leopard. I do know that no special drivers are required to use this enclosure. It is supported using the USB mass storage drivers included with XP and OS X. It should also work fine using the mass storage support in Windows 7, no? FWIW, I have also tried using 32-bit Windows 7 on both my desktop, a Gigabyte GA-965P-DS3 with a Pentium Dual-Core E6500 @ 2.93GHz, and on my early 2008 MacBook. I see the same failure in both cases that I see with 64-bit Windows 7. So it doesn't appear to be specific to one hardware platform. I'm hoping someone out there can help me either get the enclosure to work in Windows 7 or convince me that the enclosure hardware is bad and should be RMAed. At the moment though an RMA seems pointless since this appears to be a (Windows 7) device driver problem. I have tried to track down any updates to the mass storage drivers included with Windows 7 but have so far come up empty. Heck, I can't even figure out how to place a bug report with Microsoft since apparently the grace period for Windows 7 email support is only a few months. I came across a link to some USB troubleshooting steps in another question. I haven't had a chance to look over the suggestions on that site or try them yet. Maybe tomorrow if I have time ... ;-) I'll finish up with some more details about the problem. When I connect the enclosure using USB to Windows 7 at first it appears everything worked. Windows detects the drive and installs a driver for it. Looking in Device Manager there is an entry under the Hard Drives section with the title, Hitachi HDT721010SLA360 USB Device. When you open Windows Disk Management the first time after the enclosure has been attached the drive appears as "Not initialize" and I'm prompted to initialize it. This is bogus. After all, the drive worked fine in XP so I know it has already been initialized, partitioned, and formatted. So of course I never try to initialize it "again". (It's a 1 GB drive and I don't want to lose the data on it). Except for this first time, the drive never shows up in Disk Management again unless I uninstall the Hitachi HDT721010SLA360 USB Device entry under Hard Drives, unplug, and then replug the enclosure. If I do that then the process in the previous paragraph repeats. In Ubuntu the enclosure never shows up at all at the file system level. Below are an excerpt from kern.log and an excerpt from the result of lsusb -v after attaching the enclosure. It appears that Ubuntu at first recongnizes the enclosure and is attempting to attach it, but encounters errors which prevent it from doing so. Unfortunately, I don't know whether any of this info is useful or not. excerpt from kern.log [ 2684.240015] usb 1-2: new high speed USB device using ehci_hcd and address 22 [ 2684.393618] usb 1-2: configuration #1 chosen from 1 choice [ 2684.395399] scsi17 : SCSI emulation for USB Mass Storage devices [ 2684.395570] usb-storage: device found at 22 [ 2684.395572] usb-storage: waiting for device to settle before scanning [ 2689.390412] usb-storage: device scan complete [ 2689.390894] scsi 17:0:0:0: Direct-Access Hitachi HDT721010SLA360 ST6O PQ: 0 ANSI: 4 [ 2689.392237] sd 17:0:0:0: Attached scsi generic sg7 type 0 [ 2689.395269] sd 17:0:0:0: [sde] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) [ 2689.395632] sd 17:0:0:0: [sde] Write Protect is off [ 2689.395636] sd 17:0:0:0: [sde] Mode Sense: 11 00 00 00 [ 2689.395639] sd 17:0:0:0: [sde] Assuming drive cache: write through [ 2689.412003] sd 17:0:0:0: [sde] Assuming drive cache: write through [ 2689.412009] sde: sde1 sde2 [ 2689.455759] sd 17:0:0:0: [sde] Assuming drive cache: write through [ 2689.455765] sd 17:0:0:0: [sde] Attached SCSI disk [ 2692.620017] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2707.740014] usb 1-2: device descriptor read/64, error -110 [ 2722.970103] usb 1-2: device descriptor read/64, error -110 [ 2723.200027] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2738.320019] usb 1-2: device descriptor read/64, error -110 [ 2753.550024] usb 1-2: device descriptor read/64, error -110 [ 2753.780020] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2758.810147] usb 1-2: device descriptor read/8, error -110 [ 2763.940142] usb 1-2: device descriptor read/8, error -110 [ 2764.170014] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2769.200141] usb 1-2: device descriptor read/8, error -110 [ 2774.330137] usb 1-2: device descriptor read/8, error -110 [ 2774.440069] usb 1-2: USB disconnect, address 22 [ 2774.440503] sd 17:0:0:0: Device offlined -

Today I recieved a 1394b 9 pin to 1394a 6 pin cable which allowed me to connect the "EZQuest Pro" via Firewire. Everything works. When I use Firewire I can connect whether I'm using Windows 7 or Ubuntu 10.04. I even tried booting my Gigabyte desktop as an OS X 10.6.3 Hackintosh and it worked there as well. (Though if I recall correctly, it also worked when using USB 2.0 and booting OS X on the desktop. Certainly it works with USB 2.0 and my MacBook.) I believe the firmware on the device is at the latest level available, v1.07. I base this on the excerpt below from the OS X System Profiler which shows Firmware Revision: 0x107. Bottom line: It's nice that the enclosure is actually usable when I connect with Firewire. But I am still searching for an answer as to why it does not work correctly when using USB 2.0 in Windows 7 (and Ubuntu ... but really Windows 7 is my biggest concern).

• Padding error when using RSA Encryption in C# and Decryption in Java

  - by Matt Shaver

  Currently I am receiving the following error when using Java to decrypt a Base64 encoded RSA encrypted string that was made in C#: javax.crypto.BadPaddingException: Not PKCS#1 block type 2 or Zero padding The setup process between the exchange from .NET and Java is done by creating a private key in the .NET key store then from the PEM file extracted, created use keytool to create a JKS version with the private key. Java loads the already created JKS and decodes the Base64 string into a byte array and then uses the private key to decrypt. Here is the code that I have in C# that creates the encrypted string: public string Encrypt(string value) { byte[] baIn = null; byte[] baRet = null; string keyContainerName = "test"; CspParameters cp = new CspParameters(); cp.Flags = CspProviderFlags.UseMachineKeyStore; cp.KeyContainerName = keyContainerName; RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(cp); // Convert the input string to a byte array baIn = UnicodeEncoding.Unicode.GetBytes(value); // Encrypt baRet = rsa.Encrypt(baIn, false); // Convert the encrypted byte array to a base64 string return Convert.ToBase64String(baRet); } Here is the code that I have in Java that decrypts the inputted string: public void decrypt(String base64String) { String keyStorePath = "C:\Key.keystore"; String storepass = "1234"; String keypass = "abcd"; byte[] data = Base64.decode(base64String); byte[] cipherData = null; keystore = KeyStore.getInstance("JKS"); keystore.load(new FileInputStream(keyStorePath), storepass.toCharArray()); RSAPrivateKey privateRSAKey = (RSAPrivateKey) keystore.getKey(alias, keypass.toCharArray()); Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding"); cipher.init(Cipher.DECRYPT_MODE, privateRSAKey); cipherData = cipher.doFinal(data); System.out.println(new String(cipherData)); } Does anyone see a step missing or where the padding or item needs to be changed? I have done hours of reading on this site and others but haven't really found a concrete solution. You're help is vastly appreciated. Thanks. -Matt

• Using 32bit COM object from C# or VBS on Vista 64bit and getting error 80004005

  - by alexandroid

  I need some mind reading here, since I am trying to do what I do not completely understand. There is a 32-bit application (electronic trading application called CQG) which provides a COM API for external access. I have sample programs and scripts which access this API from Excel, .NET (C++, VB and C#) and shell VBScript. I have these .NET applications as source code and as compiled executables (32-bit, compiled on Windows XP). Now I have Windows Vista Home 64-bit which makes my head to spin. Excel examples work just fine (in Excel 2003). Compiled .NET sample executables work as well. But when I am trying to run .NET C# sample converted to and compiled by Visual Studio C# Expression, or run the VBScript script, I am getting error 80004005 when trying to create an object. Initially the .NET application also gave me 80040154 but then I figured how to make it produce 32-bit code and not 64-bit, so now the errors in C# and VBScript applications are the same. That's all the progress I got for now. And yes, I tried running 32-bit versions of cscript.exe/WScript from SysWOW64 folder on my VBS, but still the result is the same (80004005). How to solve this problem? I am almost ready to believe it is practically impossible, but the fact that Excel VBA works and .NET executables compiled on Windows XP run just fine just makes me angry. There should be a way to beat this thing (some secret which probably only Windows Vista developers know)! I will appreciate any help! PS: I believe code samples do not make much sense here, but this is the line of VBScript which fails: Set CEL = WScript.CreateObject("CQG.CQGCEL.4.0", "CEL_") And this is C#: CQGCEL CEL = new CQGCEL(); Update: Forgot to say UAC is off, of course. And I am working from account with administrator priviledges. I also tried watching which registry keys are read using Process Monitor but everything looks OK for GUIDs of this object. I could not recognize some other GUIDs so I am not sure whether they were critical or not. Is there a chance that this COM object uses Internet Explorer and gets the wrong one (like Internet Explorer 7 instead of Internet Explorer 6 engine or something)?
