The problem with : Handles Label1.Click, Label2.Click, Label3.Click
is that it assumes that Label2 CAN be clicked at all which may not be true at all
( if, for instance, Label2 is entirely inside Label1 ).
The good news for me is that I have solved my problem otherwise.
I have since discovered the wonderful world of Tags,
meaning I only need 2 lines of code such as :
Dim btnClicked As Label = DirectCast(sender, Label)
Dim XY As Integer = Integer.Parse(btnClicked.Tag)
So just make sure Label97 is tagged as 97 and so end of.
