hi. i'm new to programming PDAs. i'm currently writing a program that displays
a menu (like in a restaurant situation) and transmits data (the customer's
orders) frm the PDA via serial communication. I'm writing in C++ using
CodeWarrior9.
i've a problem - i am only able to check the checkboxes but not uncheck it. any
insight to how to solve this? below is a segment of my codes. pls do comment.
thx ..
rgds,
JSY

frmP = FrmGetActiveForm();
ControlType *ctl1;
ctl1 =
(ControlPtr)FrmGetObjectPtr(frmP,FrmGetObjectIndex(frmP,MainChickenBox));
chickenBoolean = (Boolean)CtlGetValue(ctl1);
handled1 =true;
