In Delphi 2 i use the DataModule.
In my tables i have fields which require value so i don't
need to write a control and exception code to test if
a value is present. it's "automatic" !!!
But when a valu miss i have this exception message 'cannot focalize invisible windows'
(it is a translation the message is in French Langage)
Hello... I Try your solutions but the exception event seemed raised BEFORE the OnValidate Event
(I Try to put a break at the top of this procedure with the key F5 but the
exception event raised before this.
