It's possible with native FM tools. Add a global number field, default 0. [zc_closeWindow_gn] Add a script along these lines: Prevent close window: If( yourTableName::zc_closeWindow_n = 0 ) Show Custom Dialog ( yourText why user can't use the stop light ) Halt scriptEnd If If( yourTableName::zc_closeWindow_n = 1 ) Close Window ( Current Window ) End If Exit script
In File --> File Options Go to tab Script Triggers Link the script to "OnWindowsClose" Find a way to set the global field to 1 when needed or authorized. Something like a close Window button on your layout. Put a Set Field line in the script linked to that button that sets the zc_ field to 1, call the Prevent close window script, reset the global to 0 Or tweak the script with a variable. Hope this helps JW
