TQDB, TQDBItem, TQDBView
Declaration
property WarnReadOnly : TWarningEvent;
Description
Whenever an attempt is made to modify a ReadOnly QDB file it triggers an EQDBReadOnly exception or, if a handler has been assigned for it, the WarnReadOnly event. You can choose to respond in either way.
If you wish to ignore all such events you must supply an empty WarnReadOnly event handler.
The Add, Change, Delete, & Kill methods, for example, will not operate when the ReadOnly property is true.
