'People who live in windowed environments shouldn't cast pointers.'
On the other hand, as I get told by my 'design committee' -A range of options implies one of them must always be selected, to be user friendly this should be the most likely (default). "None of the above" should be another option button if valid. As I recall the original term was radio button in referance to push button station change buttons.
My understanding of a range of option buttons is that it implies not so much that one must always be selected, but that only one can be selected. I guess one can also get what SonOfEmidec1100 is saying, but what if there is a list of items, only one of which can be selected, but it is not necessary to select one? Credit goes to johnwm for his solution. What I have seen for this is having an extra option button, setting it to selected and making it invisible.
On the other hand, I recently had to deal with a user that wanted the functionality of radio buttons, but wanted to use checkboxes instead. So the requirements were:
1) Use Checkboxes.
2) Only one could be checked.
3) There could be none checked.
I put them into a frame and used the Click event to determine if the value was checked. If so, I set the rest to vbUnchecked.
It was a hack, but it gave the user what they wanted (not to be confused with what they NEEDED.)
