Firstly, see how much more readable your question is using the correct formatting? always use the [code block] around code (<pre></pre>).

Secondly, avoid the name main for any object! The Main method has a special significance in any C# program (and C/C++), using it as a name will end in disaster at some point. I would suggest FormMain or something similar.

It seems that your problem is in the middle code block where you are creating a whole new main and calling ShowMenu(); on that. What you really want is to call ShowMenu on the existing main instance.

The easiest way to rectify this in your situation is to show the login form using ShowDialog and forget about the MdiChild thing for it. You can then set the DialogResult of the login form and test that in the main form.

C#

if(ls.ShowDialog(this) == DialogResult.Ok)
{
    ShowMenu();
}
ls.Dispose();
