simple vertex shader stuff

Hey, I'm trying to get into this whole shader business, but I'm confused. All I want this one to do is set the diffuse color to green // setup shader DWORD dwDecl[] = { D3DVSD_STREAM(0), D3DVSD_REG(0, D3DVSDT_FLOAT3 ), //input register v0 D3DVSD_REG(5, D3DVSDT_D3DCOLOR ), // input register v5 D3DVSD_REG(7, D3DVSDT_FLOAT2 ), // input register v7 D3DVSD_REG(8, D3DVSDT_FLOAT2 ), // input register v7 D3DVSD_END() }; // the vertices im using use(D3DFVF_XYZ | D3DFVF_DIFFUSE | D3DFVF_TEX2) // set constants FLOAT fMaterial[4] = {0,1,0,0}; d->SetVertexShaderConstant(5, fMaterial, 1); // define shader const char BasicVertexShader[] = "vs.1.1 \n""mov oD0, c5 \n"; // create shader ID3DXBuffer *pVs; DWORD shader; D3DXAssembleShader(BasicVertexShader, sizeof(BasicVertexShader) - 1, 0, NULL, &pVs, NULL); d->CreateVertexShader(dwDecl, (DWORD*)pVs->GetBufferPointer(), &shader, 0 ); d->SetVertexShader( shader ); // end I do all of that in the initialization function, if that helps. It doesn't change a damn thing. PS - there is a backslash in between the vs.1.1 and the mov instructions, but the forum erases it. Just so you know it's not that.

Alright, changed to a hardware processing device, still doesn''t display anything. I haven''t moved the code to the rendering loop yet because it should still work until I actually move the camera. Nothing is drawn.
