Try:
//Get your checkbox object pointer
CtlSetValue (*controlP, 0);
//Now, repeat for the other two controls to uncheck them all.
//The value 0 is for off, if you want to programmatically check one,
//change the value to 1
If you don't have them grouped together, then you CAN have more than
one checked, but when they're in a group, only one of them in that
group can be checked.
