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.

Hi Oleg,

Any idea why the TaskDialog returns 8 when you click a custom button with an ID of 2?

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

Hi friends.

Is there a way to set the taskdialog's cancel button property?

I mean, I can set the default button, but I can't set the cancel button.

I have a task dialog with 3 buttons. If the user presses the Esc key, the second button fires. I need that when the user presses the Esc key, the third button fires, not second.

Regards,

Elvis
