WD97: EnableCancelKey Fails to Reset After Macro Completion

Article ID: 185166 - View products that this article applies to.

This article was previously published under Q185166

SYMPTOMS

When you use the Visual Basic for Applications EnableCancelKey Property with the wdCancelDisabled constant to prevent CTRL+BREAK from interrupting a macro, CTRL+BREAK continues to be disabled after the macro has finished executing. This behavior is different from the behavior described in the EnableCancelKey Property Help topic, which states the following:

The EnableCancelKey property is reset to wdCancelInterrupt when your code stops running.

NOTE: The wdCancelInterrupt constant resets the EnableCancelKey Property to allow a macro to be interrupted by CTRL+BREAK.

To work around this problem, make sure the EnableCancelKey Property is reset to wdCancelInterrupt at any point before macro termination occurs.

The following example Visual Basic for Applications macro sets an error trap to trap an error that may occur. Note that the EnableCancelKey Property is reset to wdCancelInterrupt at the point where the macro is terminated.

     Sub IsLastTableRow()

      ' Disable CTRL+BREAK.
      Application.EnableCancelKey = wdCancelDisabled

      ' Set error trap.
      On Error GoTo ErrorHandler

      ' Check if insertion point is in last row of a table.
      ' If the insertion point is within a vertically merged
      ' cell, an error will occur.
      MsgBox Selection.Rows(1).IsLast

   ErrorHandler:
     
      If Err.Number <> 0 Then
         MsgBox Err.Description
      End If
      
      ' Re-enable CTRL+BREAK.
      Application.EnableCancelKey = wdCancelInterrupt
      
   End Sub
