如何用postmessage从一个视图向另一个视图发送消息

Question

我的代码：
::PostMessageA((CResultView*)(PubVarFuncs::pResultView),WM_MY_MESSAGE,0,0);
        其中PubVarFuncs::pResultView是目标视图的指针。
报错：
        error C2664: “PostMessageA”: 不能将参数1 从“CResultView *”转换为“HWND”
我将(CResultView*)换成HWND也不对。

Answer 1

::PostMessageA(((CResultView*)(PubVarFuncs::pResultView))->m_hWnd,WM_MY_MESSAGE,0,0);

Answer 2

((CResultView*)(PubVarFuncs::pResultView))->PostMessage(WM_MY_MESSAGE, 0, 0);

Answer 3

::PostMessageA(PubVarFuncs::pResultView.m_hWnd,WM_MY_MESSAGE,0,0);

Answer 4

((CResultView*)(PubVarFuncs::pResultView))->PostMessage(WM_MY_MESSAGE, 0, 0);
