Error Handling

[ellehcsim]

hi guys!!

is there such a thing like this in VFP...?

(start of code)
...
...
...
(do something here)
...
...
if (condition)
GOTO LABEL sample_label
else
...
...
...
(do something again)
...
...
endif

...
...
...
(series of codes)
...
...
...
RETURN

sample_label:

...
...
...
(do some other stuff)
...
...

it works like an ON ERROR GOTO command in VISUAL BASIC. Do we have this kind of procedure in VFP.

or is there any other way on how can i achieve this kind of code structure.

thanks guys!!!

You can:
ON ERROR DO MyErrorHandler

where MyErrorHandle is a procedure

PROCEDURE MyErrorHandler
... code here

ellehcsim,

You can't use GOTO in VFP to branch to another line of the program. For error handling, you need ON ERROR.

GOTO does something quite different in VFP: it moves the record pointer to a particular record number.

yes, does that PROCEDURE can be placed inside an EVENT? let say for example, can i include that PROCEDURE inside the BUTTON CLICK EVENT?

THANKS AGAIN!

 

[Mike Lewis]

, can i include that PROCEDURE inside the BUTTON CLICK EVENT?

No. You can't put PROCEDURE ... ENDPROC (or FUNCTION .. ENDFUNC) inside event code (or any other method code). But you can put it in a PRG, and still call it from the event code.
