why does the acadApp need to be visible?

    I'm wondering if there is a reason for why when manipulating the AutoCAD
    application via COM is it necessary to have it's window be visible:

    acadApp.Visible = true;

    If it is not visible this ocurrs:

    An unhandled exception of type
    'System.Runtime.InteropServices.COMException' occurred in ConvertDWG.exe
    Additional information: AutoCAD main window is invisible

    Any insight:

    Thanks,

    Alex

    What API call does the exception occur on? I have done quite a bit of
    stuff with c# (looks like the language you are using) without any bit
    of AutoCAD visible (though I did have my form visible).
