Thanks everyone for all your inputs. Here is the final code that works fine
with no more memory leak. Thanks againn everyone.
textH = FldGetTextHandle(GetObjectPtr(MainFieldRisk));
if (!textH)
{
textH = MemHandleNew(8);
}
str = MemHandleLock(textH);
doubleToStr(str, PI, 2);
MemHandleUnlock(textH);
FldSetTextHandle(GetObjectPtr(MainFieldRisk),textH);
FldDrawField(GetObjectPtr(MainFieldRisk));
return handled;
}
