OK, I named them in ther menu-editor like File, Open, Close and Exit, just for 
the right understanding.

You can simply control them by using

File.Enabled = TRUE	'Or FALSE
Open.Visible = FALSE	'Or TRUE

Every entry has his properties. In the IDE you can type 'File.' and the 
possible properties are poping up. So you can set Close.Visible/Enabled = 
False by default (in the menu-editor) and set it on 'True' in the subroutine 
where the open-file-dialoge appears (Or where ever you know that there is a 
file to close), after a valid file was choosen...
