D3D Initialization Failed

post the code so we can help or look for examples, there are about a zillon.

What does the debug output tell you when the debug Direct3D runtimes are selected in the control panel and your application is run in a debugger (or with a debug output viewer) ?

When a DirectX call fails, if the debug runtimes are in use, then as well as returning an error code (such as D3DERR_INVALIDCALL), the runtime will also output a message such as "Direct3D9: (ERROR) :Invalid value for BackBufferFormat. ValidatePresentParameters fails" to your debug output window.

Here is where it fails:

CBase::m_pD3D = Direct3DCreate9(D3D_SDK_VERSION);	if(CBase::m_pD3D==NULL)        return E_FAIL;

It worked with 9.0b

And it does not do an "error", rather, it just returns NULL, no errors, no debug problems.

Is DirectX 9.0c installed on your machine?

Compiler error or runtime error?

If it's a compiler error, then maybe it can't find the libs or the headers. Did you set the directories in Project->Settings? Tell us what it says.

If it's a runtime error, then the only thing I can think of is that maybe the drivers for your card aren't supported, or something along those lines.

EDIT: Since you said it worked with 9.0b but not with 9.0c, then your runtime dlls are probably 9.0b while your header files and libs are 9.0c. Calling the Direct3DCreate9(D3D_SDK_VERSION) function asks for 9.0c when the runtimes are only b. That would make that error make sense to me.
