The OS automatically frees handles that are associated with the form's text
fields when the form is closed. I think your problem is that when you
assign a new handle to your field, you're not freeing the old one.
Try doing this:
> h = MemHandleNew(128);
> p = MemHandleLock(h);
> StrCopy(p, defaultText);
> MemHandleUnlock(h);
Handle oldText = FldGetTextHandle(pFld); // get the old text handle
> FldSetTextHandle(pFld, h);
if (oldText) MemHandleFree(oldText); // free the old text handle if it
exists
Your new handles will be freed automatically as long as they are associated
with a field.
Best of luck
