Hi everyone. I'm new here as you can see ;) I have a problem with a source code from a book I own. The window shows up just for a second and than closes itself. Here is the code:

I'm not sure where is the mistake but I think it may be in this line:

hr = g_d3dDevice->CreateInputLayout(layout, numElements, passDesc.pIAInputSignature, passDesc.IAInputSignatureSize, &g_layout);

Debugger also say so. What should I change? I would be grateful if someone can help me.

What return code did you get in hr and what got printed to the output panel?

Output console says that the third parameter in CreateInputLayout is corrupt:

D3D10: CORRUPTION: ID3D10Device::CreateInputLayout: Third parameter is corrupt. [ MISCELLANEOUS CORRUPTION #15: CORRUPTED_PARAMETER3 ]

Could someone check what's wrong?

EDIT: I checked one more thing. The HRESULT of this line:

g_technique->GetPassByIndex(0)->GetDesc(&passDesc);

is E_FAIL.

Can you show content of the file shaders.fx?

Shader.fx content:

struct VS_INPUT{   float4 Pos : POSITION;};struct PS_INPUT{    float4 Pos : SV_POSITION;};PS_INPUT VS(VS_INPUT input){   PS_INPUT output = (PS_INPUT)0;   output.Pos = input.Pos;   return output;}float4 PS(PS_INPUT input) : SV_Target{   return float4(1, 0, 1, 1);}technique10 PassThrough{   pass P0   {      SetVertexShader(CompileShader(vs_4_0, VS()));      SetGeometryShader(NULL);      SetPixelShader(CompileShader(ps_4_0, PS()));   }}

Well, probably I can help you.
In your code:

g_technique = g_shader->GetTechniqueByName("PassThorugh");

In shaders.fx:

technique10 PassThrough

The names are different.

RomanAlex it isn't a problem ;) However I solved it by reinstalling VS. The problem must have been somewhere in there.
