Ok I am creating an excel add-in... it has 6 options (checkboxes)

any combonation can be used (these turn on and off print options)

I want to make the toolbar button display an image representing whats turned on / off...

I need to know How many combonations are possible with 6 checkboxes? (No value of 2 (greyed) allowed .. so it will be just 1/0)

is it 27 combos? or am I waaay off? my brain is shot right now! lol

but what would be the best way to figure out which button pic to use?

I am thinking.. each checkbox TAG will have a 1 or 0, then build a string..
111010 and name the image in the res file accordingly?

sound good?
