• Game Technologies: DirectX, XNA, XACT, etc. Any other way to buy an XNA subscription?

  For some reason or another my Xbox isn't accepting my credit card info (I think it may be due to the form not having an "Address line 2" field and I live in an apartment, I've checked and doublehecked all the info and the account has an ample amount of money in it), so is there any other way for me to get an XNA Creators Club subscription I tried looking to see if I could add my credit card info via Windows Live, but that didn't work out. About 60% of the reason I got this thing is because I could write programs for it, if anyone knows how to help me out I'd really appreciate it. Thanks, Johnny I'm not 100% sure but you may be able to add a credit card by going to http://billing.microsoft.com I ...Show All

• Visual Studio Express Editions OutOfMemory Exception Error

  I'm working on a rather complicated program using signature tablets. Someone signs the tablet, displaying their signature on screen. That signature is then broken down into a unicode byte string to be saved into a database. So far, so good. When I open a second form, designed to display entries from the database, it gets as far as the code below and give me an error message saying 'OutOfMemory Exception is unhandled'. This is the code designed to retrieve the unicode string from the database and turn it back into a signature. Dim ImgData As String ImgData = RegisterdbDataSet.Time_In_Table.NewTime_In_TableRow.Signature_Data() Dim bytes As Byte () = System.Text.Encoding.Unicode.GetBytes(ImgData) FileOpen(1, Envir ...Show All

• Visual Basic Unable to cast COM object of type 'X.YClass' to interface type 'X._Y'.

  Dear all, I'm getting this nasty error and I cannot find any answers (google didn't help either). Here's the thing: I'm calling a VB6 DLL from a VB.NET (VB2005) application. This is the error I get when I call the DLL: Unable to cast COM object of type 'X.YClass' to interface type 'X._Y'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{780BDA61-8169-4A5D-AD31-59A902BC3B84}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). Strange thing is, sometimes my code works properly, and the next hour I get this error. I rebuild the DLL, unregistered and re-registered the DLL, swept through the internet and the ...Show All

• Visual Basic MsgBox always return "no" regardless of what the user click

  I am using VS2005 and have a messagebox inside of an event that does not work properly. The code is below: If Microsoft.VisualBasic.MsgBox( "Do you want to save your changes" , MsgBoxStyle.YesNo) = MsgBoxResult.No Then Exit Sub End If The problem is regardless of whether the user clicks Yes or No, it always returns No. If I add another MsgBox in the code immediately before the if statement, then the if statement will always work properly.

• .NET Development BiDi32.dll...

  On VB6 I used this function BiDiConvertOemToAnsi to transfer from "DOS hebrew" into "Windows Hebrew" I tried working with the function and dll on .NET but got this message: A call to PInvoke function 'Test1!Test1.Form1::BiDiConvertOemToAnsi' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature. Can someone help me work this out Hmm, there's nothing special about those characters. Unless they are the special quotes that, for example, Word generates when the "smart quotes" option is turned on. Then the ...Show All

• Visual Studio Express Editions are methods called asynchronously in the same thread better than those called in another thread?

  i was just wondering since calling methods asynchronously in the same thread acts just like calling the method on another thread. so which is better or preferred by you programmers out there are methods called asynchronously in the same thread better than those called in another thread SJWhiteley Are there any good descriptions of how the multithreading of VB.NET actually work Of course I have tried the help files, but they do not give the required overview.

I then found an application, which used BeginInvoke to display data received from a serial port. It works fine, but for a long time I could not fi ...Show All

• Visual Studio Quickest way to Download all folders and files after initial connection to ini - VSS 2005

  Just installed VSS 2005. I connected to our DB ini. What's the quickest way to create all the folders in my wwwroot that exist in our VSS datbase Do I have to do this manually as I have been doing by going into VSS, and setting the working folder and creating the folders from there Or, can I just go to our server, copy the entire structure down, then go back into source safe and set each working folder I just want to know if it is safe to copy down from a mapped drive or something, all the folders manually or do I need to go through VSS.

• Windows Forms Access list of files in MSI in custom action

  Hi All, I have created a VS deployment project to copy “my.dll” file in a particular folder. Initially we were copying this dll on target machine manually. But if I build my.dll with some changes into it and try to copy by using installer (created by VS deployment), then my.dll file won't get overwritten. This is because both dll has same version. If the dll from my installer has version greater than already existing dll file then the old file get overwritten.

I need to convert this to a string for the further handling. For smaller data stuff works fine. Any ideas how to convert the data to a string Thanks Dob I agree that you should use streaming. But keep in mind that if you use the XmlDocument class, you will still lay a heavy burden upon the memory because de class will load the entire document at once. If possible try using a XmlReader class because this uses real streaming. ...Show All
