Problem with PostMessage() in CView derived class

Hello,

I am trying to use PostMessage() to send a message to my CView derived class. I have a project that is SDI and my view class is called CMyView, which is derived from CFormView.

Here is the relevent code:

Code:



in my MyView.h file:



    afx_msg LRESULT OnUpdateData(WPARAM wParam,LPARAM lParam);



in my MyView.cpp file:



BEGIN_MESSAGE_MAP(CMyView, CFormView)

    ...

    ON_MESSAGE(WM_USER_DATA_MESSAGE, OnUpdateData)

END_MESSAGE_MAP()



LRESULT CMyView::OnUpdateData(WPARAM wParam, LPARAM lParam)

{

    ...

    return 0;

}



in my App.cpp file:



#define WM_USER_DATA_MESSAGE 1027



// getting view handle

CMyView* viewHandle = CMyView::GetViewHandle();

CWinThread* pThread1 = AfxBeginThread(MessageHandlerThread, &viewHandle, THREAD_PRIORITY_NORMAL, 0, 0);



UINT MessageHandlerThread(LPVOID lParam)

{

     HWND hWnd = ((CMyView*)lParam)->GetSafeHwnd();

     PostMessage(hWnd, WM_USER_DATA_MESSAGE, 0, (LPARAM)data);

}

For some reason, after PostMessage() is called, the OnUpdateData() function is never called. Does anyone know why not?
