A other example:
set for all the buttons that 'group' to the the same name (i.e. 'Calculator')
and
set the 'Tag' property to what what the key represents.
Public Sub Calculator_Click()
Select Case Last.Tag
Case '-'
total = memory + number
Case '+'
total = memory + number
Case '='
Display.text = total
Default
number = (number * 10) + Last.Tag
End select
End
You can use the caption but if you publish it in multiple
languages then 'Clear' is 'Wissen' in Dutch. The .Tag can be
used as unique identification of the key pressed and set for
ever by you.
This way the code behind stay for ever the same (till bug found :) ).
