Hello there,

I've pinned the crash down to its position and it turned out to be:

dev->CreateVertexShader(vBlob->GetBufferPointer(),vBlob->GetBufferSize(),NULL,&vs);

It is inside "void initPipeline()"...

Both Pixel and Vertex Shader creation crashed the program, I don't even know what to think. Anyone has any ideas ?

Did shader compile successfully? I cannot see other reason why it'd crash.

Most likely vBlob is NULL.

[attachment=15502:Desktop.zip][attachment=15502:Desktop.zip]I don't know what do you mean by Shaders compiling, but the statements where there are "compiled into blobs" is fine, it is the very creation I mentioned.

Yes the shader file is in the projects and I have copied over the necessary x86 .dll to where the .exe is (will probably ask how to get rid of it later).

I don't know how to check for those error codes you mentioned, I don't think it will be useful if it just returns true or false since it crashes on that statement anyway.

Please see attached videos of the crash and debug.

Bump.

Guys, Have I said something wrong or does nobody know for real ?

Those videos show nothing we could use. it would crash only if shader didn't compile successfully (assuming your code is like the one you posted - without error checking).

Try

ID3D10Blob *VS, *PS;
D3DCompileFromFile(L"shaders.hlsl", 0, 0, "VShader", "vs_5_0", 0, 0, &VS, 0);
D3DCompileFromFile(L"shaders.hlsl", 0, 0, "PShader", "ps_5_0", 0, 0, &PS, 0);

Instead of your

ID3D10Blob *vBlob,*pBlob;
D3DCompileFromFile(L"Shaders.hlsl",NULL,NULL,"PShader","ps_5_0",NULL,NULL,&pBlob,NULL);
D3DCompileFromFile(L"Shaders.hlsl",NULL,NULL,"VShader","vs_5_0",NULL,NULL,&vBlob,NULL);

See if that works.

?Actually nevermind that just retried your code and it worked fine for me, although it didn't first time around and as of yet i can't see why.

Ugh... I read about the "macros" and put that shader compilation call into:

	if( SUCCEEDED( dev->CreateVertexShader(vBlob->GetBufferPointer(),vBlob->GetBufferSize(),NULL,&vs) ) )
		MessageBox(NULL,L"Vertex Shader Compiled!",L"Shader Compilation Result",MB_OK | MB_ICONEXCLAMATION);
	else
		MessageBox(NULL,L"Vertex SHader FAILED!",L"Shader Compilation Result",MB_OK | MB_ICONEXCLAMATION);

Still crashes the same way, which I assumed the checking is useless since the call itself crashes for no reason...

Any more ideas ?
