VC自定义消息

时间：2010-12-21 来源：kenter

#define WM_MY_MESSAGE (WM_USER+100)

在dlg.cpp中添加

UINT CTestMessageDlg::OnMyMessage(WPARAM wParam, LPARAM lParam)
{
    // TODO: 处理用户自定义消息...
    CString *dd = (CString*)lParam;
    AfxMessageBox(*dd);

    return 0;
}

ON_MESSAGE(WM_MY_MESSAGE, OnMyMessage)

dlg.h添加

afx_msg UINT OnMyMessage(WPARAM wParam, LPARAM lParam);

测试

代码 void CTestMessageDlg::OnButton1()
{
    // TODO: Add your control notification handler code here
    CString dd = "Hello World";
    ::SendMessage(m_hWnd, WM_MY_MESSAGE, (WPARAM)(HWND)NULL, (LPARAM)&dd);
}
