expression   A variable that represents a Form object.

Parameters

Name Required/Optional Data Type Description
Cancel 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.

The Undo event for forms occurs whenever the user returns a form to its original state by clicking the Undo button, pressing the ESC key, or calling the Undo method of the specified form.

Example

The following example demonstrates the syntax for a subroutine that traps the Undo event for a form.

Visual Basic for Applications 
  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
