Changing Errorsys

[Kleyber]

Hi all,

Has anyone changed the errorsys in order to quit the program only if we pulse the button QUIT? My idea is if we pulse other button, the program continues normally without quit. Is it possible? If so, how can I do it in my errorsys?

Best Regards,

It's only possible for recoverable errors. You can BREAK if you want let the main program to handle the error, return .T. to retry the operation or return .F. to ignore the error.

Hi Enrico,

Thanks (as always) for your answer. I was looking at a program made in Delphi where all the errors are showed, but the user can ignore them and come back to the program. Which cases are non recoverable errors? Do you have an example to show it?

Unrecoverable errors are the ones with

Code: Select all

oErr:Severity = ES_CATASTROPHIC //3

This is a sample of error trapping:

Code: Select all

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL nVar, oErr

    ERRORBLOCK( { | oErr | Break( oErr ) } )

    BEGIN SEQUENCE
        nVar *= 2
    RECOVER USING oErr
        ? "oErr:Description", oErr:Description
        ? "oErr:CanDefault", oErr:CanDefault
        ? "oErr:CanRetry", oErr:CanRetry
        ? "oErr:CanSubstitute", oErr:CanSubstitute
        ? "oErr:Severity", oErr:Severity
    END SEQUENCE

    RETURN NIL

Thanks a lot, Enrico. I'll take a good look.
