Answer 1

You need to implement the -panel:userEnteredFilename:confirmed: delegate method. Returning nil will suppress the standard panel. However, I warn you that you better have a good reason for overriding it otherwise there will be plenty of puzzled/irritated users!

Answer 2

Thanks a lot! I have got the resolution!
