MFC下如何使用WM_COPYDATA来把消息传给另外一个进程?

Question

能给个稍微详细一点的例子么?谢谢啦^^

Answer 1

LRESULT xxx::OnCopyData(UINT nMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
PCOPYDATASTRUCT lpcds;

hwndSending = (HWND)wParam;
lpcds = (PCOPYDATASTRUCT)lParam; if( lpcds->cbData>=6 && lpcds->lpData )

得到相应窗口的句柄,发送消息(),
在利用oncopydata()接收就可以！A  // Specifies data to be passed to the receiving application. 
   CString csStr = L"hello";
    stDataStruct.dwData = 0;                                   
    // Specifies the size, in bytes, of the data pointed to by the lpData member.
    stDataStruct.cbData = 2 * csStr.GetLength();        
    // Pointer to data to be passed to the receiving application. This member can be NULL
    stDataStruct.lpData = csStr.GetBuffer( stDataStruct.cbData );  
    csStr.ReleaseBuffer();
 ::SendMessage(m_hIPMProcess, WM_COPYDATA, NULL, ( LPARAM )&stDataStruct);
B
BOOL CMYMainFrm::OnCopyData(CWnd* pWnd, COPYDATASTRUCT* pCopyDataStruct) 
{
