I assume your Main form is an MDI form and DocWind is a child? If so,
I know of two approaches:
1. Duplicate all Main's menus on DocWind and call Main's menu events
in DocWind's menu events. Then you could add the popup menu to
DocWind. It would work but you'd have to keep them in step and
remember to make changes to both forms. This approach is best suited
to when you have several types of child forms, a fair amount of menu
functionality that's common to all forms, and where the different
child types each have a fair amount of specialised menu functionality
that is not common. The best way to copy the menu structure is to open
the two .FRM files in Notepad and just copy and paste it across.
2. Put the popup menu on the Main form and put code in DocWind to
activate it. This approach is best for when there's only one type of
child and they all need the popup menu. The code to activate the popup
looks like this:
Me.PopupMenu Main.mnuPop etc.
From what you say, option 2 sounds like what you want.
