How does on error work ?

[INFORMAT]

Hello,

I have a form where I put an error and the 'on error' command shows a modal form. When the program reached the error line he shows me the error form but still continue the program.

When I put an second error in the program the 'on error' command shows a model form with only the last error.

Is it possible when an error occured, the program shows an error form and the program leaves the method where the error occurred when clicking OK.

Thanks four your time and answer.

Check out the ON ERROR in the MSDN, you can use the RETRY, IGNORE or SET STEP ON to debug.

It is also possible to use the Error method of your class, to catch the error.

There was a freely avaliable article from FoxTalk in the MSDN on line library. Haven't got the link right now though...sorry.

Hi Informat,

Yes, you can control what program execution returns to in the call stack. Refer to the RETURN command in the VFP docs utilizing the TO ProcedureName clause.

The 2nd article doesnt apply to VFP6, but is FYI. Also remember, when you redirect execution up the call stack, you are also not allowing the bypassed method/program to perform any clean up operations such as closing a table it had opened, releasing any object references it had created, etc...
