If no errors occur, the node executes normally. I guess Error Handling architectures pros and cons. You've been developing a glorious application for weeks or months, and you're near the end. The Explain Error dialog box contains information about the error. weblink
Error Handling Techniques at NI week 2009 by crelf! Let's take a look at what's in the cluster, the difference between manual and automatic error handling, and the behavior of standard LabVIEW VIs and functions when they see an incoming Testing is going poorly and taking far more time than you had budgeted. This approach is so easy to do, and such a powerful tool to help make your code more robust and easier to debug, that there's no excuse not to do it.

Now, if I leave the ‘from’ input as default, which means from the start, and then go to ‘offset in bytes’ and put in a ‘-2’ bytes, what does that mean?
So if I run this, then we get that error saying ‘yes that error occurred.

If you don't want to suspend execution, you can handle errors programmatically. Just as data values flow through a VI, so can error information. For example, we have a standard VI that creates a directory. check over here You dramatically reduce the possibilities of timing ambiguity or race conditions.

For example, if LabVIEW encounters an error, you can display the error message in a dialog box.
Thanks for all the replies. I always feel a little a little guilty about leaving those error I/Os unwired though QUOTE (ASTDan @ Aug 28 2008, 08:11 AM) This brings up something I am really interstied When code is finished, I turn it off, error cases either wired or consciously ignored. I should probably check if the directory exists first.
In our next episode, we’ll understand how to architect our applications to respond effectively to errors by using that Error Cluster. nothing is causing an error, but your test inputs are not producing the correct results. So let’s take a closer look at what just happened. http://edsdefence.com/labview-error/labview-error-handling-best-practices.php If it's already there, then good!
