Hi all,
Given that the internet connection is always active, my program processes ra
w data and sends reduced files via email (using STMP email send me
ssage.vi) to users on a timely basis. The problem is that when I loose
the internet connectiton (l
et's say if a technitian needs to work on the internet connection
and has to shut it down for a while), an error occurs an
d the program gets stuck since, I guess, it can't find the internet connecti
on. Is there any way&n
bsp;to make my program skip a particular step (in this case, STMP email send
message.vi) and move on to the next step without stopping the program in ca
se of errors caused by loosing the connectiton?
Thanks in advance for your inputs.
Yoon.

- hi,
You can use the case structures with the error cluster
Below is the description for using error handling with clusters but it appli
es to your case.:
When you wire an error cluster to the selector terminal of a case struc
ture, the case selector label displays two cases, Error and No Error, and th
e border of the Case structure changes color?red for Error and green for No
Error. If an error occurs,
the Case structure executes the Error subdiagram.
So in the error sub diagram you can proceed further withour stopping you pro
gram.
hope it helps
let me know the results.
Regards

- It works now. However, I did not change anything (I did not change the
check mark to red. I still leave it as green). What I had in the screen shot
works just fine.
Thanks anyway for trying to help.
