Can't pass a ListBox as a ListBox - must be a Variant??
 

Please have a look at the 2 subs below

Private Sub POLines_Change()
UpdateTransferButton POLines, AddPSLines
End Sub

Private Sub UpdateTransferButton(ByRef lb As ListBox, ByRef b As
CommandButton)
Dim index As Integer
For index = 0 To lb.ListCount - 1
If lb.Selected(index) Then
b.Enabled = True
Exit Sub
End If
Next
b.Enabled = False
End Sub

From the first subroutine, I'm trying to call the second one, which takes as
parameters a ListBox and a CommandButton. I'm getting a runtime error on the
call form the first subroutine indicating that I have type mismatch. Can
someone tell me why??

When I change the 2 parameters to Variants, everything is OK.

Why can't I pass a ListBox as a ListBox and same with a CommandButton

Thanks
Mike

Hi

You have to use the named arguments:

Private Sub POLines_Change()
Call UpdateTransferButton(lb:=POLines, b:=AddPSLines)
End Sub

or

Private Sub POLines_Change()
UpdateTransferButton lb:=POLines, b:=AddPSLines
End Sub

Regards,

Per

How are the variables POLines and AddPSLines declared?
The type declarations in the called sub should be the same as the original type declarations.

In addition to the other responses, sometimes there's a conflict between
classes with the same names. Try calling out those arguments as

MSForms.ListBox
MSForms.CommandButton

and see if that takes care of it.
