VFP Error 2

[mantry]

I have an app developed in VFP7.
In a prg I have a procedure which will accept three parameters. When a call is made to this procedure with more than 3 parameters, I get a VFP error "Must specify additional parameters" which makes sense. But I would like to trap this message and return the message as an XMLString

Question: Is it possible for me trap this message and populate it. If yes, can you let me know how.

Thanks,
Mantry

You should be able to trap the error with a global error handler. I have an example of one for download from

http://www.peisch.com/downloads.html,

in the file called ErrLog.zip. It stores the data in a DBF file, but you can figure out how to translate that into XML.

Mantry,

In addition to what Barbara told you (and, by the way, the download she mentioned is very useful; it helped me out of a difficult situation once) ...

Basically, the way to trap an error in VFP is to use ON ERROR. That command will let you set up an error handler. An error handler is an ordinary VFP routine which has access to details of the error (error number, message, etc.).

You can do (almost) anything you like in an error handler, including creating an XML file containing the error details.

Sorry if I am telling you stuff you already know.
