  • WM_SendMessageNoPara(): hWinSrc member of received message is zero

    I'm using WM_SendMessageNoPara() function to send a message from window A to window B, when the user press a button on window A. The member hWinSrc of the received message by window B is zero. Is it normal?

  • Hi,

    Yes, that is normal. The prototype of the function is as follows:

    void WM_SendMessageNoPara(WM_HWIN hWin, int MsgId);

    It does not consider the sender. But you can use WM_SendMessage() and fill the message structure with the required information.
