Question about TRY ... CATCH ... END
Posted: Thu Nov 04, 2010 12:36 PM

Hello,

I was just wondering if it is possible to suppress certain errors by using TRY ... CATCH ... END.

What do I mean : is it possible to suppress a certain error (example Bound Array Access) by using TRY ... CATCH ... END ? But if other errors might occur, I do want the error-message.

Thanks a lot in advance

Michel,

Maybe something like this:

Code (fw): Select all Collapse

TRY
...
CATCH oError
  if oError:genCode != ...
     // do whatever
  endif
END

James

Thanks a lot for your answer.

But can you tell me where I can find a list of the codes oError:GenCode ?

Thanks.

xharbour\include\error.ch

EG_ARRACCESS is array access.

Harvey,

No, this code goes in your app. It is strategically placed where you want to override errorsys.

Search the forum for "CATCH" to see some examples.

James,

Maybe another question about this subject.

I know now how to pick up a certain error by using TRY ... CATCH ... END.

But I want other error-messages to be shown. Is it possible to establish this ?

Thanks a lot in advance.

Michel,

I'm sure it is possible, but I haven't used TRY/CATCH much and I don't know how. Did you try searching the forum?

James,

Thanks a lot for your answer.

No, I didn't search the forum yet. But I will do that and in case I can find an answer, I'll put it here.

Have a nice weekend.

Dear Driessen

I do this to examine messages..

Code (fw): Select all Collapse

TRY
...
CATCH oError
  if ValType( oError) == 'O'
     xBrowse( oError )         //this works
  endif
END

Kind Regards,
Frances
