Zero is LabVIEW's choice (and the choice of most other programming languages, as well) for the "no error" case. Judicious use of text editors, spreadsheet programs, and short LabVIEW routines can quickly extract the appropriate data for pasting into the table. How many times have you wired in a separate dialog box to alert the user to the details of the error? jvh75021 Active Participant 08-05-2010 08:52 AM Options Mark as New Bookmark Subscribe Subscribe to RSS Feed Highlight Print Email to a Friend Report to a Moderator I am getting reports from this content
An error dialog appears and displays the customized error code and description. It's easy! YourFeedback! You also know that they remember the type of dialog specified most recently, so that a dialog type could be set in one place and be effective for all instances of http://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/creating_user_defined_erro/
In the development situation you always refer to the file(s) in labview\user.lib\errors. If you have several error wires and you want to retain the information from all of them your only built-in option is to build an array of error clusters to transport LV error cluster is the recommended carrier.
NoteAs an alternative to steps 6 through 8, you can wire a numeric constant with a value of 5008 to the Error Cluster From Error Code VI. You can use an enumerated type for the errors, and then define some offset within the 5000-10000 region that your errors will slip into. Changes to error code text files take effect the next time you start LabVIEW. The LabVIEW code is platform independent, but the DLLs are not.
To facilitate this, we have upgraded our workhorse Chained Find First Error.vi to accept the new error enums interchangeably with the old-fashioned error codes (by incorporating Variant to Error Code within LV help and LV examples are not very informative in that domain.

It will find the first non-zero entry among its three error inputs: an error in cluster, an array of Error Codes, and a single Error Code. (By far the most common Wouldnt it be nice if lists of errors could be combined easily on a session-by-session basis so that youre only treating the errors pertinent to the current setup?

Poor|Excellent Yes No Document Quality? To edit the error codes and descriptions, select the error code or text you want to change, and enter your edits.
Apparently the creator didn't create a custom error codes file as I don't see one in the .lvproj file. http://ascadys.net/labview-error/labview-error-10.html Typing the label each time is bad enough, but trying to keep track of what number was assigned to what error is a bear. (I resorted to a cheat sheet diagram Of course, if one set of error codes overlaps another you should get multiple possible explanations, labeled by package, just as the overlapping DAQ and GPIB codes are handled. Switch to the VI in which you defined your custom error code, and run the VI again.
Using this feature each application can programmatically set all its own error code descriptions when it initializes for instance. This feature is transparent to all built-in functions so it won't break any of your normal code. Thanks for the post. have a peek at these guys In the standard error dialog, this would appear immediately after "occurred at".
Since the actual errors start at enum value 1, the numerical value needs to be one less than the value at which you want the error codes to start. Define global error descriptions at runtime LabVIEW lets you define custom error code descriptions statically by use of error code files, but there is no built-in functions to do it at In reality, these and other device specific files should more probably be in the appropriate device folder in the instr.lib folder.

The first time in any session that one of these error definition VIs is called, it parses the information into forms more useful to the computer (Figure 4).
If there is an error, speed (at the microsecond level) is not a concern; things are already broken. All rights reserved. In that we can add any new errors or remove errors. check my blog NoteYou must manually create an errors folder in the LabVIEW\user.lib directory to organize your error code files. I could check all the front panels but there are 1600 of them. Different projects use different equipment. User error are reserved in the code range... Not sure how you will narrow it down if the resulting error message doesn't help. Figure 2: C Header File In many cases, you will have a C header file or the equivalent from the vendor that contains all the pertinent information other than the LabVIEW
