• Game Technologies: DirectX, XNA, XACT, etc. This chap says

  In a thread on this forum there is an interesting discussion that I'm wondering what your opionions are concerning it. (I hope this is the right forum for this..) Chap A Graphics API's completely extract the graphics cards so the programmer doesn't have to worry about dealing with each type of card a user might have. There is no reason he should ever have to or even want to deal directly with the graphics card. He also doesn't have to have a language with a direct interface to assembley. Some languages are better then others for a project like this, but being able to paste assembley into the code is not a r ...Show All

• Visual Studio Express Editions Visual C++ Express application to Run on .Net 1.1

  I have installed Visual C++ Express, which installed .Net 2.0. I have bult a small application in Visual C++ Express which runs fine of this development machine however the application is destin to run on machines that only have .Net 1.1 installed. I have read that applications built on .Net 2.0 are not forward compatible to run on earlier versions on .Net. Therefore my question is "In Visual c++ Express how do I build an application that will run on .Net 1.1" Thanks AFAIK, you can't.  But, .NET versions live side by side, your users can install .NET 2.0 and 1.1 will still ...Show All

• Windows Forms inserting cell values in DataGridView manually one at a time

  Hi, I am new to vb.net programming and have the following question. I am getting data from database into 3 separate components.

• Game Technologies: DirectX, XNA, XACT, etc. Debugging program that won't start

  Whenever I try to start my program, I get a dialog box saying "The application failed to initialize properly (0xc0000022). Click on OK to terminate the application". With the debugger, it does the exact same thing, giving me no opportunity to find out what is going on; if I try to break it once the dialog box is up, I get another dialog "Unable to break execution. Please wait until the debuggee has finished loading, and try again" The only vaguely informative piece of information is a message in the debug window: "Debugger: An unhandled non-continuable exception was thrown during process load" ...Show All

• Windows Forms Text not showing up in Listbox

  I am having problems populating a listbox and having the text show up. When I first encountered the problem, it was within a more complicated program. So, I began a new C# Windows application program, used the default "Form1" and drug a listbox on it. I renamed the listbox to lstCSAList to match the other program I was working on. In design time, I clicked on the ellipse, under Items where it says "(Collection)". I added, line1 line2 line3 In the Form1_Load subroutine, I placed the following code: private void Form1_Load( object sender, System.EventArgs e) { lstCSAList.Items.Add("Dummy&qu ...Show All

• Visual Basic Please help with Process close and saving, also timer.sleep use

  Hi, I want to be able to control a program through a vb.net window app (start, manipulate, close, and save) that has a form with a button to intiate it. As a first step I am experimenting with notepad to get the code down. I can easily create a window app that can start notepad, write a few sentences and then close notepad but focus is then immediately returned to my windows form and my subsequent sendkeys (tab & enter) that were meant for the save message box that comes up happens on my form instead. How can I shift focus back to the notepad's save message box (instead of my form) so that I can also save the file using sendkeys Here i ...Show All

• .NET Development dbf index in vb2005

  Hi all, I am new to VB2005 and need help. I have some data in dbf and I need to find some records in them. How do I set indexes for this files. Many thanks Regards Trivun Hi Trivun, Although there is more than one program that creates DBF files, I'll assume your DBFs are FoxPro DBFs. There are two types of indexes for FoxPro DBFs. One will have an IDX extension and the other will have a CDX extension. The IDX indexes are seldom used any more so I'll assume you have a CDX file with the same name as the table you want to access. The FoxPro data engine will automatically make use of any indexes that ar ...Show All

• Visual Basic Irritiated - can you help?

Where has VS2005 put my file Mat Hi, To see the installed location of your application, you can add some debug code in your Form_Load. Something like this should work: MsgBox(My.Application.Info.DirectoryPath)   But to answer you question about why you aren't seeing your changes inside VS, it's because you are using a local SQL ...Show All
