Required |
Integer |
Set this argument to True to cancel the undo operation and leave the control or form in its edited state. |
Remarks
The Undo event for controls occurs whenever the user returns a control to its original state by clicking the Undo Field/Record button on the command bar, clicking the Undo button, pressing the ESC key, or calling the Undo method of the specified control. The control needs to have focus in all three cases. The event does not occur if the user clicks the Undo Typing button on the command bar.
Example
The following example demonstrates the syntax for a subroutine that traps the Undo event for a form.
Private Sub Form_Undo(Cancel As Integer)
Dim intResponse As Integer
Dim strPrompt As String
strPrompt = "Cancel the undo operation?"
intResponse = MsgBox(strPrompt, vbYesNo)
If intResponse = vbYes Then
Cancel = True
Else
Cancel = False
End If
End Sub
