TaskDialog cancel button

I'm using 12.1.1, and pressing the ESC key doesn't click any button unless that button has a ID of 2. But the strange thing is, the ShowDialog and ButtonClick events return an ID of 8 for the clicked button (even if no button has an ID of 8). Can anyone else confirm this strange behaviour? I assume it is a bug.

This means you would have to have some unusual code to get the third button to be a cancel button:

With Me.TaskDialog1       .Reset             .AddButton "OK", 100       .AddButton "Try Again", 101       .AddButton "Cancel", 2             If .ShowDialog = 8 Then          ' 8?? Why does pressing the ESC key return 8 instead of 2?          Debug.Print "Cancelled"       Else          Debug.Print "Not Cancelled"       End If    End With

Playing with the Vista TaskDialog sample I find that

      If you have a standard CANCEL button enabled,  clicking CANCEL produces buttonclick event with ID = 8.

      Pressing the ESC key produces buttonclick event with ID = 8

     If I add my own Custom Button with caption = &MyButton   and ID = 11
       then pressing  ALT+M  produces buttonclick event with ID = 11.

My guess is that the ESC keypress is hardwired to the inbuilt Cancel Button event.

With that in mind you can program around this if you need to (as you have done).
I wouldn't call it a bug -- just a feature of the TaskDialog.  But it would have been useful if this was mentioned in the documentation.
