Thread: How to get rid of MDI window

I created a new, basic MFC app using the AppWizard in VS .NET, and I want to get rid of the MDI window that is there when I start the application. How do I do this?

That worked, but why? It implies that the command line parameters specify a new window, but I can't find where the parameters are specified.

EDIT: Ok, I'm guessing the application is designed to open a new document if there are no command line parameters. The easy way out is to do what you did, but what if I actually want to use the command line? I can't just comment out those lines. Are there any other solutions to this? Perhaps I could inherit the CCommandLine class and override some of the functions. Is that a good idea?

Yep, that's a good solution. Inherit from CCommandLineInfo, and in your new constructor, change m_nShellCommand to FileNothing, like so:

Code:

class DisplayGraphicsCmdLine : public CCommandLineInfo
{
public:
	DisplayGraphicsCmdLine() {m_nShellCommand=FileNothing; }
};
