保存和使用其他类的句柄

保存：

       char windowname[256];

       HWND m_hdlg_Configuration;

        sprintf(windowname,"%s","Configuration");
SetWindowText(windowname);//设置窗口标题名
CWnd*   pWnd;
pWnd=FindWindow(NULL,windowname);
m_hdlg_Configuration=pWnd->GetSafeHwnd();//得到该窗口句柄

使用：

        CWnd *pWnd;
pWnd=CWnd::FromHandle(m_hdlg_Configuration);
pWnd->SendMessage(WM_CLOSE,NULL,1);
