Declaration:property OnFileCheck: TOnFileCheckEvent;
{TOnFileCheckEvent = procedure (Sender: TObject; FileName: string; var FileDoesExist: boolean) of object; }

The OnFileCheck event occurs after the user has entered a filename. The event handler has to check whether the entered file already exists. OnFileCheck is only triggered if UseStandardDialog is FALSE.
