Hoi,

I'm using a macro to copy data from file-1 to file-2.
In file-2 (which is not my file) an automatic ChangeEvent is build in
by another person on such a way that when I copy data to a specific
datafield I get an automatic popup with a question.
It's not allowed for me to change this code, but............ I don't
want that pop-up when I'm copying data into it. Is there a way I can
disable that code when I'm copying.

Something like:
'disable code for AutoEvent.....
'copy data
'enable code for AutoEvent....

below the code which I found in that file-2 as I mentioned.

Private Sub Worksheet_Change(ByVal Target As Range)
Dim ChangedRange As Range
Set ChangedRange = Range("I25:I33")
If Union(Target, ChangedRange).Address = ChangedRange.Address Then
CheckResult '=run another macro
End If
End Sub

regards,
Johan
