This code displays a problem when run

[**Developer**]

I've been asking about a Menu problem I have without results.

So here is a test case I've developed that shows the problem.

Simply create a soultion with one project containg one form and replace the
form code with this.

Run it, right click and select Edit/Paste Special/Test1

Then try to do that again

I beleive that Test1 will not show the second time!

How come?



Thanks

This code should fix your problem. Looks like you have to refresh the
menu with MenuItemPasteSpecial after you make a change like that....

Private Sub ContextMenuEditor_Popup(ByVal sender As Object, ByVal e
As System.EventArgs) Handles ContextMenuEditor.Popup


MenuItemPasteSpecial.MenuItems.Clear()

MenuItemPasteSpecial.MenuItems.Add(New MenuItem("Test1",
AddressOf ZZ_Click))

MenuItemPasteSpecial.MenuItems.Add(New MenuItem("Test2",
AddressOf ZZ_Click))

MenuItemEdit.MenuItems.Clear()

Me.MenuItemEdit.MenuItems.Add(Me.MenuItemPasteSpecial)

End Sub

I wonder why that works because you're removing and then adding
MenuItemPasteSpecial which displayed OK. It's the items of
MenuItemPasteSpecial that didn't.

In any event, that does solve the problem as I presented it but typically
one would not want to clear MenuItemEdit because it would have many items on
it.

I wonder what made you think of that. Do you have any other ideas that may
sove the more general problem?

Thanks
