ID3DXEffectStateManager::SetVertexShader

A callback function that must be implemented by a user to set a vertex shader.

HRESULT SetVertexShader(
  LPDIRECT3DVERTEXSHADER9 pShader
);

Parameters

pShader

[in] A pointer to a vertex shader object. See IDirect3DVertexShader9.

Return Values

The user-implemented method should return S_OK. If the callback fails when setting the device state, either of the following will occur:

• The effect will fail during ID3DXEffect::BeginPass.
• The dynamic effect state call (such as IDirect3DDevice9::SetVertexShader) will fail.

Requirements

Header: Declared in D3dx9effect.h.
