Vertex shader problem

chick80

Ok, I'm trying to use vertex shader, but I have some problem...
Here's the code I'm using (note that the shader doesn't really do anything... it just expects the world*view*projection matrix in c0->c4 and then passes the data through as it is):

[code]
const char VertexShader[] =
"vs.1.1
"
"m4x4 oPos, v0, c0
"
"mov oT0, v7";
ID3DXBuffer *VertexShaderBuffer;

DWORD declaration[] =
{
D3DVSD_STREAM(0),
D3DVSD_REG(D3DVSDE_POSITION, D3DVSDT_FLOAT3),
D3DVSD_REG(D3DVSDE_NORMAL, D3DVSDT_FLOAT3),
D3DVSD_REG(D3DVSDE_TEXCOORD0, D3DVSDT_FLOAT2),
D3DVSD_END()
};

if (FAILED(D3DXAssembleShader(VertexShader, lstrlen(VertexShader), D3DXASM_DEBUG, NULL, &VertexShaderBuffer, NULL)))
return false;

if (FAILED(D3DDevice->CreateVertexShader(declaration, (DWORD*)VertexShaderBuffer->GetBufferPointer(), &VertexShaderHandle, 0)))
return false;

VertexShaderBuffer->Release();
return true;
[/code]

The problem is with CreateVertexShader that returns D3DERR_INVALIDCALL.
I don't really understand where's the error, so I hope that someone out there can find it for me!!! ;-)

Thank you

Try to use this:
: [code]
: if (FAILED(D3DXAssembleShader(VertexShader, lstrlen(VertexShader)-1, D3DXASM_DEBUG, NULL, &VertexShaderBuffer, NULL)))
: return false;
: [/code]

Thank you, but I found that the error wasn't there, but in the function that chooses the device to use. It choosed a device which has no vertex shader support so I didn't see anything.
Btw, now it's all working!
