Re: How to successfully change Control text repeatedly?

[Henk Jonas]

Why do you verify it? You assume, that something behind sizeof(ControlType) is the actual label store. You prevent further OS versions from growing the ControlType structure. But I can't see a reason for this check.

This now generates warning or error messages in Palm
OS5:
freeTxtP = (char *)ctlP + sizeof(ControlType);
oldTxtP = (char *)CtlGetLabel(ctlP);
CtlSetLabel(ctlP, txtP);
if(oldTxtP != freeTxtP)
