The video card is a Nvidia GeForce 8800 GT

also, it would help if you provided more information about the graphics card in each of your machines...

I can create a new VB project, add the DirectX and Direct3D references, and put this code in the main form:

    
            Imports Microsoft.DirectX 
        
            Imports Microsoft.DirectX.Direct3D 
        
            Public Class Form1 
        
                Dim device As Direct3D.Device 
        
                Dim MyTriangleStrip(3) As CustomVertex.PositionColored 
        
            End Class

MyTriangleStrip is the line that is causing the error in the original post.

It might be helpful if you can tell what instruction throw this exception.

DirectX problem in Windows 7 (program has stopped working)

I'm trying to run a VB2008 application that uses DirectX under Windows 7 RC (64 bit). This is an application I wrote on a Vista machine. When I run the compiled application in Windows 7, I get the error message:

myappname has stopped working

From within VB2008 Express Edition, I am able to build the solution, but I cannot debug it. Trying to debug will throw the error:

InvalidOperationException was unhandled.
An error occured creating the form. See Exception.InnerException for details. The error is: is not a valid Win32 Application. (Exception from HRESULT: 0x800700C1)

This same project will debug, compile, and run fine under Windows XP or Vista (both test boxes are 32 bit).
A VB2008 project that does not require DirectX will run find under Windows 7.
The March 2009 DirectX SDK is installed on the Windows 7 machine, same as the XP and Vista machines.

Any idea how to get DirectX applications to work under Windows 7?

Thanks,
Lance
