Writing your own is a bit excessive. The most logical suggestion I think is to simply check the file after the dialog returns, and if it is a file extension you do not support, then inform the user of his low IQ and to try again. A user will only try it once, so it's not worth lots of additional programming time.

The standard Opendialog is a wrapper for the Windows Common Control and cannot be extended to do this because there are no notifcation messages sent when the user enters anything in the FileName edit area. > Wayne, > If they type (e.g.) *.* in the file name box, they get to see all > files > and can then select anything. > I need to support a few (completely different) file types which are > processed in different ways, but I do not want to allow the user to > pick > some rubbish instead. > Ken _______________________________________________ Delphi mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi
