ISpThreadTask::WindowMessage

  • Article

This application-specific method processes window messages, if the application needs a window. If the caller of ISpThreadControl::StartThread passes a non-null window pointer, this method must be implemented. In this case, the implementation must use a MessageWaitForMultipleObjects loop in its ISpThreadTask::ThreadProc method.

virtual LRESULT STDMETHODCALLTYPE WindowMessage(
  void* pvTaskData,
  HWND hWnd,
  UINT Msg,
  WPARAM wParam,
  LPARAM lParam
) = 0;

  • wParam
    [in] Information that depends on the message specified by the Msg parameter.
  • lParam
    [in] Information that depends on the message specified by the Msg parameter.
