Hi NG

I am making a GUI with some checkboxes and i am VERY focused on making the
everyday use of the GUI as uninterrupted as possible e.g. no popup windows
with "you can't do this: click ok"-stuff.

The GUI is like this: The user chooses some options with by using
checkboxes. Some options exclude others or are dependant on others e.g
option A can not be choosen if option B is choosen. Further B migth depend
on C and so on.

The way i handle this is that if i choose A then i do a CheckBox_B.Enable =
False.
if i click on A one more time (deselct it) then i do a CheckBox_B.Enable =
True.
In this way the user can never choose A and B at the same time.

The user migth think: "why the heck cant i choose B?" and the logical thing
might then to click on B - enventhough CheckBox_B.Enable = False. Here is
then what i imagine should happen: When the user click on the non-enabled
checkbox B, then the backcolor of checkbox A should be changed to red as to
indicate the blocking option.

Can this be done in ANY way in VBA. I.e i know that somehow the
eventlistener stops listening to all the .enabled = false widgets (buttons
etc.) in the GUI and thus cant catch a click on checkbox_B

Any comments greatly appreciated
