I find dynamically changing the values in labels during the running
the program a very useful technique, though one that has to be done
very carefully.
This has been discussed many times in the past
1) Make sure the size of the label at design time is as large as the
largest field you are going to put into it, otherwise you stomp
over your memory (nasty!)
2) Set the value of the label before you call FrmDrawForm() is fine.
Get a pointer to the label with CtlGetValue(), and then do
a StrCopy(). But don't draw it to the screen at this point
3) To change the label after the screen is drawn, you have to
a) hide it
b) change the value with step #2 above
c) show it
