That is not a good design choice.  Your MDI form should be your MainForm
instead.

If you make your login form be the MainForm, the program will terminate when
the login form is closed.

You probably have the form set to Auto-Create in the Project Options.

Don't make the Login form be the MainForm at all.  The MDI form should be
the MainForm.  Then modify the project's WinMain() function directly to
display the login form manually before the MainForm is created.  If the
login form rejects the login, you can terminate the program without running
the MainForm at all.  For example:

    #include "LoginForm.h"

    WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
    {
        try
        {
            Application->Initialize();

            TLoginForm *login = new TLoginForm(Application);
            int Result = login->ShowModal();
            delete login;

            if( Result == mrOk )
            {
                Application->CreateForm(__classid(TMDIForm), &MDIForm);
                Application->Run();
            }
        }
        catch(const Exception &E)
        {
            Application->HandleException(&E);
        }

        return 0;
    }
