• Why would javascript click-areas not be working in IE8?

  - by Edward Tanguay

  I'm trying to find a bug in an old ASP.NET application which causes IE8 to not be able to click on the following "button" area in our application: <td width="150px" class="ctl00_CP1_UiCommandManager1i toolBarItem" valign="middle" onmouseout="onMouseOverCommand(this,1,'ctl00_CP1_UiCommandManager1',0,0);" onmouseover="onMouseOverCommand(this,0,'ctl00_CP1_UiCommandManager1',0,0);" onmousedown="onMouseDownCommand(this, 'ctl00_CP1_UiCommandManager1', 0, 0);" onmouseup="onMouseUpCommand(this, 'ctl00_CP1_UiCommandManager1', 0, 0);" id="ctl00_CP1_UiCommandManager1_0_0"> <span style="width:100%;overflow:hidden;text-overflow:ellipsis;vertical-align:middle;white-space:nowrap;"> NEW </span> </td> When we switch IE8 to IE7 compatibility mode, the problem disappears, IE7 is able to click on it. Since the above HTML is generated by a third party control (Janus, http://www.janusys.com/controls), we don't have the source code. has anyone experienced any similar problems with IE8? I've determined that it actually fires the onMouseDownCommand command also the CSS of the button area is different in IE8, it doesn't have color shading that it does in IE7. I can imagine that somewhere the HTML is not valid and IE8 being stricter is not playing along, but where? any advice on how to narrow in on this bug welcome ANSWER: Turned out to be that the application was not checking the navigator.agent for "MSIE 8.0" and was thus treating IE8 has a non-Internet-Explorer browser. Thanks Lazarus for the tip, the IE8 Javascript debugger is very nice, like a Firebug for IE, will be using it more!

• Forking in PHP on Windows

  - by Doug Kavendek

  We are running PHP on a Windows server (a source of many problems indeed, but migrating is not an option currently). There are a few points where a user-initiated action will need to kick off a few things that take a while and about which the user doesn't need to know if they succeed or fail, such as sending off an email or making sure some third-party accounts are updated. If I could just fork with pcntl_fork(), this would be very simple, but the PCNTL functions are not available in Windows. It seems the closest I can get is to do something of this nature: exec( 'php-cgi.exe somescript.php' ); However, this would be far more complicated. The actions I need to kick off rely on a lot of context that already will exist in the running process; to use the above example, I'd need to figure out the essential data and supply it to the new script in some way. If I could fork, it'd just be a matter of letting the parent process return early, leaving the child to work on a few more things. I've found a few people talking about their own work in getting various PCNTL functions compiled on Windows, but none seemed to have anything available (broken links, etc). Despite this question having practically the same name as mine, it seems the problem was more execution timeout than needing to fork. So, is my best option to just refactor a bit to deal with calling php-cgi, or are there other options? Edit: It seems exec() won't work for this, at least not without me figuring some other aspect of it, as it waits until the call returns. I figured I could use START, sort of like exec( 'start php-cgi.exe somescript.php' );, but it still waits until the other script finishes.

• Problem with authentication from different domains using Django sessions.

  - by Greg

  Hi all, I am developing a bookmarklet which essentially adds a toolbar to a web page user is currently looking at. To use it, user needs to be logged in. To login user clicks on 'Singin' which displays a standard form containing Username, Password etc fields. When user successfully logs in they may chose to navigate to a different web-site. When on another page, they (a) re-load the bookmarklet (b) their session is retrieved from the server (c) user doesn't need to login again. Pretty standard I've would have thought. Using Django sessions and JQuery. I'm having troubles implementing the above usecase. Here are some problems I've encountered: Cross domain POST AJAX requests are disallowed. That was solved with JSONp. I doubt it is a very secure approach but for now it works. My server returns the session id in a cookie, however when the user navigates to a different page I don't really know how to retrieve that session id to send back to my server. Can I even read third party cookies from my JavaScript? I'm looking for some guidelines on implementing the above usecase. Ideally I don't want to redirect user to another page for them to sign in. Any suggestion would be greatly appreciated. Thanks.

• Does anyone know of a good Commercial WPF Web Browser Control?

  - by VoidDweller

  I have an MDI WPF app that I need to add web content too. At first, great it looks like I have 2 options built into the framework the Frame control and the WebBrowser control. Given that this is an MDI app it doesn't take long to discover that neither of these will work. The WebBrowser control wraps up the IE WebBrowser ActiveX Control which uses the Win32 graphics pipeline. The "Airspace" issue pretty much sums this up as "Sorry, the layouts will not play nice together". Yes, I have thought about taking snapshots of the web content rendering these and mapping the mouse and keyboard events back to the browser control, but I can't afford the performance penalty and I really don't have time to write and thoroughly test it. I have looked for third party controls, but so far I have only found Chris Cavanagh's WPF Chromium Web Browser control. Which wraps up Awesomium 1.5. Together these are very cool, they play nice with the WPF layouts. But they do not meet my performance requirements. They are VERY HEAVY on memory consumption and not to friendly with CPU usage either. Not to mention still quite buggy. I'll elaborate if you are interested. So, do any of you know of a stable performant WPF web browser control? Thanks.

• In Ruby, how to I read memory values from an external process?

  - by grg-n-sox

  So all I simply want to do is make a Ruby program that reads some values from known memory address in another process's virtual memory. Through my research and basic knowledge of hex editing a running process's x86 assembly in memory, I have found the base address and offsets for the values in memory I want. I do not want to change them; I just want to read them. I asked a developer of a memory editor how to approach this abstract of language and assuming a Windows platform. He told me the Win32API calls for OpenProcess, CreateProcess, ReadProcessMemory, and WriteProcessMemory were the way to go using either C or C++. I think that the way to go would be just using the Win32API class and mapping two instances of it; One for either OpenProcess or CreateProcess, depending on if the user already has th process running or not, and another instance will be mapped to ReadProcessMemory. I probably still need to find the function for getting the list of running processes so I know which running process is the one I want if it is running already. This would take some work to put all together, but I am figuring it wouldn't be too bad to code up. It is just a new area of programming for me since I have never worked this low level from a high level language (well, higher level than C anyways). I am just wondering of the ways to approach this. I could just use a bunch or Win32API calls, but that means having to deal with a bunch of string and array pack and unpacking that is system dependant I want to eventually make this work cross-platform since the process I am reading from is produced from an executable that has multiple platform builds, (I know the memory address changes from system to system. The idea is to have a flat file that contains all memory mappings so the Ruby program can just match the current platform environment to the matching memory mapping.) but from the looks of things I'll just have to make a class that wraps whatever is the current platform's system shared library memory related function calls. For all I know, there could already exist a Ruby gem that takes care of all of this for me that I am just not finding. I could also possibly try editing the executables for each build to make it so whenever the memory values I want to read from are written to by the process, it also writes a copy of the new value to a space in shared memory that I somehow have Ruby make an instance of a class that is a pointer under the hood to that shared memory address and somehow signal to the Ruby program that the value was updated and should be reloaded. Basically a interrupt based system would be nice, but since the purpose of reading these values is just to send to a scoreboard broadcasted from a central server, I could just stick to a polling based system that sends updates at fixed time intervals. I also could just abandon Ruby altogether and go for C or C++ but I do not know those nearly as well. I actually know more x86 than C++ and I only know C as far as system independent ANSI C and have never dealt with shared system libraries before. So is there a gem or lesser known module available that has already done this? If not, then any additional information as to how to accomplish this would be nice. I guess, long story short, how do I do all this? Thanks in advance, Grg PS: Also a confirmation that those Win32API calls should be aimed at the kernel32.dll library would be nice.

• Creating Dependencies Only to be able to Unit Test

  - by arin

  I just created a Manager that deals with a SuperClass that is extended all over the code base and registered with some sort of SuperClassManager (SCM). Now I would like to test my Manager that is aware of only the SuperClass. I tried to create a concrete SCM, however, that depends on a third party library and therefore I failed to do that in my jUnit test. Now the option is to mock all instances of this SCM. All is good until now, however, when my Manager deals with the SCM, it returns children of the SuperClass that my Manager does not know or care about. Nevertheless, the identities of these children are vital for my tests (for equality, etc.). Since I cannot use the concrete SCM, I have to mock the results of calls to the appropriate functions of the SCM, however, this means that my tests and therefore my Manager need to know and care about the children of the SuperClass. Checking the code base, there does not seem to be a more appropriate location for my test (that already maintains the appropriate real dependencies). Is it worth it to introduce unnecessary dependencies for the sake of unit testing?

• The "first past the post election" query problem

  - by MPelletier

  This problem may seem like school work, but it isn't. At best it is self-imposed school work. I encourage any teachers to take is as an example if they wish. "First past the post" elections are single-round, meaning that whoever gets the most votes win, no second rounds. Suppose a table for an election. CREATE TABLE ElectionResults ( DistrictHnd INTEGER NOT NULL, PartyHnd INTEGER NOT NULL, CandidateName VARCHAR2(100) NOT NULL, TotalVotes INTEGER NOT NULL, PRIMARY KEY DistrictHnd, PartyHnd); The table has two foreign keys: DistrictHnd points to a District table (lists all the different electoral districts) and PartyHnd points to a Party table (lists all the different political parties). I won't bother with other tables here, joining them is trivial. This is just a wee bit of context. The question: What SQL query will return a table listing the DistrictHnd, PartyHnd, CandidateName and TotalVotes of the winners (max votes) in each District? This does not suppose any particular database system. If you wish to stick to a particular implementation of SQL, go the way of SQLite and MySQL. If you can devise a better schema (or an easier one), that is acceptable too. Criteria: simplicity, portability to other databases.

• Problem using UnhandledException in Windows Mobile app

  - by MusiGenesis

  I have a Windows Mobile program that accesses an attached device through a third-party DLL. Each call to the device can take an unknown length of time, so each call includes a timeout property. If the call takes longer than the specified timeout to return, the DLL instead throws an exception which my app catches with no problem. The problem that I have is with closing the application. If my application has made a call to the DLL and is waiting for the timeout to occur, and I then close the application before the timeout occurs, my application locks up and requires the PDA to be rebooted. I can ensure that the application waits for the timeout before closing, under normal conditions. However, I am trying to use AppDomain.CurrentDomain.UnhandledException to catch any unhandled exceptions in the program and use the event to wait for this pending timeout to occur so the program can be closed finally. My problem is that this event doesn't seem to stick around long enough. If I put a MessageBox.Show("unhandled exception"); line in the event, and then throw a new unhandled exception from my application's main form, I see the message box for a split second but then it disappears without my having clicked the OK button. The documentation I've found on this event suggests that by the time it's called the application is fully committed to closing and the closing can't be stopped, but I didn't think it meant that the event method itself won't finish. What gives (I guess that's the question)? Update: In full windows (Vista) this works as expected, but only if I use the Application.ThreadException event, which doesn't exist in .Net CF 2.0.

• Using MD5 to generate an encryption key from password?

  - by Charles

  I'm writing a simple program for file encryption. Mostly as an academic exercise but possibly for future serious use. All of the heavy lifting is done with third-party libraries, but putting the pieces together in a secure manner is still quite a challenge for the non-cryptographer. Basically, I've got just about everything working the way I think it should. I'm using 128-bit AES for the encryption with a 128-bit key length. I want users to be able to enter in variable-length passwords, so I decided to hash the password with MD5 and then use the hash as the key. I figured this was acceptable--the key is always supposed to be a secret, so there's no reason to worry about collision attacks. Now that I've implemented this, I ran across a couple articles indicating that this is a bad idea. My question is: why? If a good password is chosen, the cipher is supposed to be strong enough on its own to never reveal the key except via an extraordinary (read: currently infeasible) brute-force effort, right? Should I be using something like PBKDF2 to generate the key or is that just overkill for all but the most extreme cryptographic applications?

• kick off a map reduce job from my java/mysql webapp

  - by Brian

  Hi guys, I need a bit of archecture advice. I have a java based webapp, with a JPA based ORM backed onto a mysql relational database. Now, as part of the application I have a batch job that compares thousands of database records with each other. This job has become too time consuming and needs to be parallelized. I'm looking at using mapreduce and hadoop in order to do this. However, I'm not too sure about how to integrate this into my current architecture. I think the easiest initial solution is to find a way to push data from mysql into hadoop jobs. I have done some initial research on this and found the following relevant information and possibilities: 1) https://issues.apache.org/jira/browse/HADOOP-2536 this gives an interesting overview of some inbuilt JDBC support 2) This article http://architects.dzone.com/articles/tools-moving-sql-database describes some third party tools to move data from mysql to hadoop. To be honest I'm just starting out with learning about hbase and hadoop but I really don't know how to integrate this into my webapp. Any advice is greatly appreciated. cheers, Brian

• VB.net Saving an MetaFile / EMF as a bitmap ( .tiff)

  - by pehaada

  Currently I have a third party control that generates a Metafile. I can save the .wmf file to disk with out issue. The problem is how do I render the Metafile as a Tiff file. Currently I have the following code to get my metafile and save it. Dim mf As Metafile = page.GetImage(TXTextControl.Page.PageContent.All) Dim enhMetafileHandle As IntPtr = mf.GetHenhmetafile() Dim h As IntPtr Dim bufferSize As UInteger = GetEnhMetaFileBits(enhMetafileHandle, 0, h) Dim buffer(CInt(bufferSize)) As Byte GetEnhMetaFileBits(enhMetafileHandle, bufferSize, buffer) Dim msMetafileStream As New MemoryStream msMetafileStream.Write(buffer, 0, CInt(bufferSize)) Dim baMetafileData() As Byte baMetafileData = msMetafileStream.ToArray Dim g As Graphics = Graphics.FromImage(mf) mf.Dispose() File.WriteAllBytes("c:\a.wmf", baMetafileData) end sub _ Public Shared Function GetEnhMetaFileBits( ByVal hEMF As System.IntPtr, ByVal nSize As UInteger, ByVal lpData As IntPtr) As UInteger End Function <System.Runtime.InteropServices.DllImportAttribute("gdi32.dll", EntryPoint:="GetEnhMetaFileBits")> _ Public Shared Function GetEnhMetaFileBits(<System.Runtime.InteropServices.InAttribute()> ByVal hEMF As System.IntPtr, ByVal nSize As UInteger, ByVal lpData() As Byte) As UInteger End Function I've tried all sort of IMAGE and Graphic calls and just can't save the meta file as a .tiff. Any suggestions would be great. I even tried to create a new bitmap and draw the metafile onto it. I always end up with a GDI exception being thrown.

• How do I POST/GET from rails to API with Nestful?

  - by Angela

  Hi, this is a pretty basic question but I'm not entirely clear how to do this. I am trying to use a third-party service that has web-based service. The service is called Postful. But I'm not clear what exactly to do? I've looked at ActiveResource (http://api.rubyonrails.org/classes/ActiveResource/Base.html) and rest-client, but I'm still not clear exactly what steps, code, and files to create. I'm trying to use Nestful but I'm not entirely clear how to make this work. http://github.com/maccman/nestful http://www.postful.com/service/mail is one of the services (details found http://www.postful.com/developer/guide#rest ), but to upload an image I have to post the following (but I'm not sure how I actually do this?). Thanks! > http://www.postful.com/service/upload > > Be sure to include the Content-Type > and Content-Length headers and the > image itself as the body of the > request. > > POST /upload HTTP/1.0 Content-Type: > application/octet-stream > Content-Length: 301456 > > ... file content here ... > > If the upload is successful, you will > receive a response like the following: > > <?xml version="1.0" encoding="UTF-8"?> > <upload> > <id>290797321.waltershandy.2</id> > </upload>

• What is the best way to process XML sent to WCF 3.5

  - by CRM Junkie

  I have to develop a WCF application in 3.5. The input will be sent in the form of XML and the response would be sent in the form of XML as well. A ASP.NET application will be consuming the WCF and sending/receiving data in XML format. Now, as per my understanding, when consuming WCF from an ASP.NET application, we just add a reference to the service, create an object of the service, pack all the necessary data(Data Members in WCF) into the input object (object of the Data Contract) and call the necessary function. It happens that the ASP.NET application is being developed by a separate party and they are hell bent on receiving and sending data in XML format. What I can perceive from this is that the WCF will take the XML string (a single Data Member string type) as input and send out a XML string (again a single Data Member string type) as output. I have created WCF applications earlier where requests and responses were sent out in XML/JSON format when it was consumed by jQuery ajax calls. In those cases, the XML tags were automatically mapped to the different Data Members defined. What approach should I take in this case? Should I just take a string as input (basically the XML string) or is there any way WCF/.NET 3.5 will automatically map the XML tags with the Data Members for requests and responses and I would not need to parse the XML string separately?

• How can I read a DBF file with incorrectly defined column data types using ADO.NET?

  - by Jason

  I have a several DBF files generated by a third party that I need to be able to query. I am having trouble because all of the column types have been defined as characters, but the data within some of these fields actually contain binary data. If I try to read these fields using an OleDbDataReader as anything other than a string or character array, I get an InvalidCastException thrown, but I need to be able to read them as a binary value or at least cast/convert them after they are read. The columns that actually DO contain text are being returned as expected. For example, the very first column is defined as a character field with a length of 2 bytes, but the field contains a 16-bit integer. I have written the following test code to read the first column and convert it to the appropriate data type, but the value is not coming out right. The first row of the database has a value of 17365 (0x43D5) in the first column. Running the following code, what I end up getting is 17215 (0x433F). I'm pretty sure it has to do with using the ASCII encoding to get the bytes from the string returned by the data reader, but I'm not sure of another way to get the value into the format that I need, other that to write my own DBF reader and bypass ADO.NET altogether which I don't want to do unless I absolutely have to. Any help would be greatly appreciated. byte[] c0; int i0; string con = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\ASTM;Extended Properties=dBASE III;User ID=Admin;Password=;"; using (OleDbConnection c = new OleDbConnection(con)) { c.Open(); OleDbCommand cmd = c.CreateCommand(); cmd.CommandText = "SELECT * FROM astm2007"; OleDbDataReader dr = cmd.ExecuteReader(); while (dr.Read()) { c0 = Encoding.ASCII.GetBytes(dr.GetValue(0).ToString()); i0 = BitConverter.ToInt16(c0, 0); } dr.Dispose(); }

• Encoding Problem with Zend Navigation using Zend Translate Spanish in XMLTPX File Special Characters

  - by Routy

  Hello, I have been attempting to use Zend Translate to display translated menu items to the user. It works fine until I introduce special characters into the translation files. I instantiate the Zend_Translate object in my bootstrap and pass it in as a translator into Zend_Navigation: $translate = new Zend_Translate( array('adapter' => 'tmx', 'content' => APPLICATION_PATH .'/languages/translation.tmx', 'locale' => 'es' ) ); $navigation->setUseTranslator($translate); I have used several different adapters (array,tmx) in order to see if that made a difference. I ended up with a TMX file that is encoded using ISO-8859-1 (otherwise that throws an XML parse error when introducing the menu item "Administrar Applicación". <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE tmx SYSTEM "tmx14.dtd"> <tmx version="1.4"> <header creationtoolversion="1.0.0" datatype="tbx" segtype="sentence" adminlang="en" srclang="en" o-tmf="unknown" creationtool="XYZTool" > </header> <body> <tu tuid='link_signout'> <tuv xml:lang="en"><seg>Sign Out</seg></tuv> <tuv xml:lang="es"><seg>Salir</seg></tuv> </tu> <tu tuid='link_signin'> <tuv xml:lang="en"><seg>Login</seg></tuv> <tuv xml:lang="es"><seg>Acceder</seg></tuv> </tu> <tu tuid='Manage Application'> <tuv xml:lang="en"><seg>Manage Application</seg></tuv> <tuv xml:lang="es"><seg>Administrar Applicación</seg></tuv> </tu> </body> </tmx> Once I display the menu in the layout: echo $this->navigation()->menu(); It will display all menu items just fine, EXCEPT the one using special characters. It will simply be blank. NOW - If I use PHP's UTF8-encode inside of the zend framework class 'Menu' which I DO NOT want to do: Line 215 in Zend_View_Helper_Navigation_Menu: if ($this->getUseTranslator() && $t = $this->getTranslator()) { if (is_string($label) && !empty($label)) { $label = utf8_encode($t->translate($label)); } if (is_string($title) && !empty($title)) { $title = utf8_encode($t->translate($title)); } } Then it works. The menu item display correctly and all is joyful. The thing is, I do not want to modify the library. Is there some kind of an encoding setting in either zend translate or zend navigation that I am not finding? Please Help! Zend Library Version: 1.11

• Design: Website calling a webservice on the same machine

  - by Chris L

  More of a design/conceptual question. At work the decision was made to have our data access layer be called through webservices. So our website would call the webservices for any/all data to and from the database. Both the website & the webservices will be on the same machine(so no trip across the wire), but the database is on a separate machine(so that would require a trip across the wire regardless). This is all in-house, the website, webservice, and database are all within the same company(AFAIK, the webservices won't be reused by another other party). To the best of my knowledge: the website will open a port to the webservices, and the webservices will in turn open another port and go across the wire to the database server to get/submit the data. The trip across the wire can't be avoided, but I'm concerned about the webservices standing in the middle. I do agree there needs to be distinct layers between the functionality(such as business layer, data access layer, etc...), but this seems overly complex to me. I'm also sensing there will be some performance problems down the line. Seems to me it would be better to have the (DAL)assemblies referenced directly within the solution, thus negating the first port to port connection. Any thoughts(or links) both for and against this idea would be appreciated P.S. We're a .NET shop(migrating from vb to C# 3.5)

• Advice welcomed on creating my own Swing component

  - by Toto

  Recently I asked which was the best Swing component to bind to a BigDecimal variable (with some particular editing properties). It turns out that none of the standard Swing components suit me completely, nor did the third-party Swing component libraries I've found out there. So I’ve decided to create my own Swing component. Component description: I want to extend JTextField or JFormattedTextField, so my new component can be easily bound to a BigDecimal variable. The component will have customizable scale and length properties. Behavior: When the component is drawn, it shows only the decimal point and space for scale digits to its right. When the component receives focus the caret should be positioned left to the decimal point. As the user types numbers (any other character is ignored) they appear to the left of the caret, only length – scale numbers are accepted, any other number typed is ignored as the integer portion is full. Any time the user types the decimal point the caret moves to the right side of the decimal point. The following numbers typed are shown in the decimal part, only scale numbers are considered any other number typed is ignored as the decimal portion is full. Additionally, thousand separators should appear as the user types numbers left to the decimal point. Invoking a getValue() method on the component should yield the BigDecimal representing the number just entered. I’ve never created my own Swing component; I’ve barely used the standard ones. So I would appreciate any good tutorial/info/tip on creating the component described. This is the only thing I've got so far. Thanks in advance.

• NSMutableArray of Objects

  First off I am very new to Objective C and iPhone programming. Now that that is out of the way. I have read through most of the Apple documentation on this and some third party manuals. I guess I just want to know if I'm going about this the correct way ... - (NSMutableArray *)makeModel { NSString *api = @"http://www.mycoolnewssite.com/api/v1"; NSArray *namesArray = [NSArray arrayWithObjects:@"News", @"Sports", @"Entertainment", @"Business", @"Features", nil]; NSArray *urlsArray = [NSArray arrayWithObjects: [NSString stringWithFormat:@"%@/news/news/25/stories.json", api], [NSString stringWithFormat:@"%@/news/sports/25/stories.json", api], [NSString stringWithFormat:@"%@/news/entertainment/25/stories.json", api], [NSString stringWithFormat:@"%@/news/business/25/stories.json", api], [NSString stringWithFormat:@"%@/news/features/25/stories.json", api], nil]; NSMutableArray *result = [NSMutableArray array]; for (int i = 0; i < [namesArray count]; i++) { NSMutableDictionary *objectDict = [NSMutableDictionary dictionary]; NSString *name = (NSString *)[namesArray objectAtIndex:i]; NSString *url = (NSString *)[urlsArray objectAtIndex:i]; [objectDict setObject:name forKey:@"NAME"]; [objectDict setObject:url forKey:@"URL"]; [objectDict setObject:@"NO" forKey:@"HASSTORIES"]; [result addObject:objectDict]; } return result; } Any insight would be appreciated ;-)

• reading dbase file without standard .dbf extension.

  - by Nathan W

  I am trying to read a file which is just a dbase file but without the standard extension the file is something like: Test.Dat I am using this block of code to try and read the file: string ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\Temp;Extended Properties=dBase III"; OleDbConnection dBaseConnection = new OleDbConnection(ConnectionString); dBaseConnection.Open(); OleDbDataAdapter oDataAdapter = new OleDbDataAdapter("SELECT * FROM Test", ConnectionString); DataSet oDataSet = new DataSet(); oDataAdapter.Fill(oDataSet);//I get the error right here... DataTable oDataTable = oDataSet.Tables[0]; foreach (DataRow dr in oDataTable.Rows) { Console.WriteLine(dr["Name"]); } Of course this crashes because it can't find the dbase file called test, but if I rename the file to Test.dbf it works fine. I can't really rename the file all the time because a third party application uses it as its file format. Does anyone know a way to read a dbase file without a standard extension in C#. Thanks.

• How to restrict access to a class's data based on state?

  - by Marcus Swope

  In an ETL application I am working on, we have three basic processes: Validate and parse an XML file of customer information from a third party Match values received in the file to values in our system Load customer data in our system The issue here is that we may need to display the customer information from any or all of the above states to an internal user and there is data in our customer class that will never be populated before the values have been matched in our system (step 2). For this reason, I would like to have the values not even be available to be accessed when the customer is in this state, and I would like to have to avoid some repeated logic everywhere like: if (customer.IsMatched) DisplayTextOnWeb(customer.SomeMatchedValue); My first thought for this was to add a couple interfaces on top of Customer that would only expose the properties and behaviors of the current state, and then only deal with those interfaces. The problem with this approach is that there seems to be no good way to move from an ICustomerWithNoMatchedValues to an ICustomerWithMatchedValues without doing direct casts, etc... (or at least I can't find one). I can't be the first to have come across this, how do you normally approach this? As a last caveat, I would like for this solution to play nice with FluentNHibernate :) Thanks in advance...

• Is there a programming toolkit for converting "any file type" to a TIFF image?

  - by Ryan

  Hello, I've written several variations of a program. The purpose of the program is to convert "any file type" to a TIFF image represenation of that file, as if it were being printed using a printer. I'm currently using a third party printer driver that I send files to, and it outputs a TIFF image. This is nice, but it requires me to use Office Interop files, and interact with each individual processing application in order to print the files. I had previously tried a toolkit, called Apose .NET, which did not rely on Office Interop, and did not require any printer driver. It did the conversion all on its own and would create a TIFF image. The problem with Aspose .NET was that it did not support a wide variety of input file types. Most notably, it can't do Visio files. My project calls for the ability to create a TIFF image for virtually "any file type". (excluding exes, music files, and stuff) I know that finding something that handles literally any file type is probably not a very feasible task, so I figure if it can at least handle all the Office file types, Adobe types, and other major standard file types, then I can write a custom extension parsing module that uses those processing applications to do the printing of any file type that can be viewed using those applications. So, does anyone know of a toolkit that can do this? Preferably one that does not rely on Office or a printer driver. It does not have to be free, or open source. Or, if you know of an amazing printer driver that does this, I'm open to that too. Thanks in advance, Ryan

• java time check API

  - by ring bearer

  I am sure this was done 1000 times in 1000 different places. The question is I want to know if there is a better/standard/faster way to check if current "time" is between two time values given in hh:mm:ss format. For example, my big business logic should not run between 18:00:00 and 18:30:00. So here is what I had in mind: public static boolean isCurrentTimeBetween(String starthhmmss, String endhhmmss) throws ParseException{ DateFormat hhmmssFormat = new SimpleDateFormat("yyyyMMddhh:mm:ss"); Date now = new Date(); String yyyMMdd = hhmmssFormat.format(now).substring(0, 8); return(hhmmssFormat.parse(yyyMMdd+starthhmmss).before(now) && hhmmssFormat.parse(yyyMMdd+endhhmmss).after(now)); } Example test case: String doNotRunBetween="18:00:00,18:30:00";//read from props file String[] hhmmss = downTime.split(","); if(isCurrentTimeBetween(hhmmss[0], hhmmss[1])){ System.out.println("NOT OK TO RUN"); }else{ System.out.println("OK TO RUN"); } What I am looking for is code that is better in performance in looks in correctness What I am not looking for third-party libraries Exception handling debate variable naming conventions method modifier issues

• thread reaches end but isn't removed

  - by pstanton

  I create a bunch of threads to do some processing: new Thread("upd-" + id){ @Override public void run(){ try{ doSomething(); } catch (Throwable e){ LOG.error("error", e); } finally{ LOG.debug("thread death"); } } }.start(); I know i should be using a threadPool but i need to understand the following problem before i change it: I'm using eclipse's debugger and looking at the threads in the debug pane which lists active threads. Many of them complete as you would expect, and are removed from the debug pane, however some seem to stay in the list of active threads even though the log shows the "thread death" entry for these. When i attempt to debug these threads, they either do not pause for debugging or show an error dialog: "A timeout occurred while retrieving stack frames for thread: upd-...". there is some synchronization going on within the doSomething() call but i'm fairly sure it's ok and since the "thread death" log is being called i'm assuming these threads aren't deadlocked in that method. i don't do any Thread.join()s, however i do call a third party API but doubt they do either. Can anyone think of another reason these threads are lingering? Thanks. EDIT: I created this test to check the Garbage Collection theory: Thread thread = new Thread("!!!!!!!!!!!!!!!!") { @Override public void run() { System.out.println("running"); ThreadUs.sleepQuiet(5000); System.out.println("finished"); // <-- thread removed from list here } }; thread.start(); ThreadUs.sleepQuiet(10000); System.out.println(thread.isAlive()); // <-- thread already removed from list but hasn't been GC'd ThreadUs.sleepQuiet(10000); this proves that it is nothing to do with garbage collection as eclipse removes the thread from the thread list as soon as it completes and isn't waiting for the object to be de-referenced/GC'd.

• JVM terminates when launching eclipse with J2SE 6.0 on mac os x (need J2SE 6.0 for Oracle enterprise

  - by rooban bajwa

  I know my issue has party been addressed at this link http://stackoverflow.com/questions/245803/jvm-terminates-when-launching-eclipse-mat-on-mac-os-with-j2se-60 but it was a year+ ago.. plus the link that's provided in there http://landonf.bikemonkey.org/static/soylatte/ does not seem to be alive (i mean the download section on that link no longer provide the 32-bit port of j2se 6.0 for mac osx 10.5) I am trying to run eclipse 3.5 on mac OSX 10.5. It works fine with J2SE 5.0. But when I installed the Oracle enterprise pack for eclipse - it requires to start eclipse with J2SE 6.0 JVM otherwise it will get disabled. Here's the exact message I get from it - "You are running Eclipse on Java VM version: 1.5.0_22 Oracle Enterprise Pack for Eclipse requires Java version 6 or higher. Click next to configure a compatible Java VM." It asks me to point to J2SE 6.0 JVM, when I do that (i.e point it to "/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home") , it asks to restart eclipse , when I do that, eclipse just bombs .. with JVM terminated error .. SO I need to start eclipse with J2SE 6.0 JVM but eclipse needs carbon which is only available in 32 bits and hence I cann't start eclipse with J2SE 6.0 JVM which is only available in 64bit mode from mac. And the site providing 32 bit port of J2SE 6.0 JVM does not seem to be active anymore.. Can someone help me on this issue, Thanks in advance,
