Massive thanks for this link.
However i did a quick test trying to place a client in the read only mode
On the startup screen i have spinner object bidirectionally bound to integer memory tag and i was able to change the value . I could not change it in the designer which worked properly.
I guess the script code and its placement is correct -right?
it did work exactly as i wanted after placing in the client startup script.
Just wonder if this should not be in the project configuration menu for more convenience as also for safety.
