CMDIChildWnd *pMDIActive; while( pMDIActive = MDIGetActive() ) { pMDIActive->SendMessage(WM_CLOSE); } Regards, Ram

yes,I did it with following code: BOOL CALLBACK EnumChildProc(HWND hwndChild, LPARAM lParam) { ::SendMessage(hwndChild,WM_CLOSE,0,0); return TRUE; } void CMainFrame::OnWindowCloseall() { // TODO: 在此添加命令处理程序代码 ::EnumChildWindows(m_hWndMDIClient,EnumChildProc,0); } life is like a box of chocolate,you never know what you r going to get.

thank you for your reply. I found anoter function: CDocTemplate* pTemplate = pDocument->GetDocTemplate(); pTemplate->CloseAllDocuments(true); though I don't know the progress of the function.

I'm glad you found this. I can't believe that EnumChildWindows() and SendMessage() were suggested.
