MFC关于解决点击关闭，对话框仍有后台程序运行问题 .

1.添加KillProcess(LPCSTR pszClassName, LPCSTR pszWindowTitle)函数；

int CTestDlg::KillProcess(LPCSTR pszClassName, LPCSTR pszWindowTitle)
{
    HANDLE hProcessHandle;  //
    ULONG nProcessID;
    HWND TheWindow;

    TheWindow = ::FindWindow( NULL, pszWindowTitle );
    ::GetWindowThreadProcessId( TheWindow, &nProcessID );
 hProcessHandle = ::OpenProcess(PROCESS_TERMINATE,FALSE,nProcessID );
    return ::TerminateProcess( hProcessHandle, 4 );
}

 

 

2.添加ON_CLOSE消息响应函数，加入KillProcess函数；

  void CTestDlg::OnClose()
{
 // TODO: Add your message handler code here and/or call default
  KillProcess(NULL,"软件的名称"); //结束进程，解决点击关闭

                                 //后台仍有进程运行！！
 CDialog::OnClose();
}
