Greetings,

I am trying to write an MFC-based application which can be run via
command line.

It should not pop up GUI if following line is executed:

C:\>myapp.exe /nogui

It should execute normally when following line is executed:

C:\>myapp.exe

I am able to parse command line arguments using CCommanLineInfo
class. If user executes the program from command prompt with /nogui
option then application should run code and it should pop up messages
as to its progress and never the main program GUI. After it has done
executing code it should gracefully exit. Need some pointers on how
to properly accomplish this. Thanks.

In CMyApp::InitInstance(), do something like:

BOOL CMyApp::InitInstance()
{
    if ( _tcsstr(m_lpCmdLine, _T("/nogui") ) // checking m_lpCmdLine is
sometimes easier than using CCommandLineInfo
    {
        // Popup messages (AfxMessageBox will work here)
       ...
      return FALSE; // don't start message pump
    }
    else // "/nogui" is not specified
    {
       // show main GUI
        m_pMainWnd = new CMainFrame();
       ....
      return TRUE; // start message pump
    }
}
