Figure 1 shows the front panel of a VI that captures the error definitions for a Dipix XPG1000 video image capture board. Then wire the error out output of the Error Cluster From Error Code VI to the error in input of the General Error Handler VI. In fact, if customized, detailed, individual comments were used religiously, only a single, generic error with no explanation at all would be perfectly suitable. You'll get automatic conversion but won't be bothered by the dots (at least they don't bother me when they are there already) and the code will make sure the data is http://edsdefence.com/labview-error/labview-error-codes-user-defined.php
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 jvh75021 Active Participant 08-05-2010 01:18 PM Options Mark as New Bookmark Subscribe Subscribe to RSS Feed Highlight Print Email to a Friend Report to a Moderator All your replies were helpful I saw this in some freeware from Moore Good Ideas, and I am sure others have done similar things. Our services Test & Measurement Process & Automation Simulation LabVIEW & TestStand News & Knowledge Expression Parser awards finalist NI selected our Expression Parser toolset as finalist for the Product of http://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/creating_user_defined_erro/
You also can define custom error codes by creating an XML-based text file and adding the error codes and messages to the text file. 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 In that case you can distribute your custom xml error file with the app.

How about being able to set a default error dialog type for the entire sessionand to change it temporarily or permanently at any point in the program? Your cache administrator is webmaster.
A Select function could then be wired to choose between "no error" and your error of choice depending on some test on your diagram (Figure 7). Well, I could maybe use the General Error Handler VI as such but I would then want to make a local copy and initialize the user error codes/messages arrays to my Now your detailed comment can be handled exactly like the rest of the error information! (Be sure to check what the Smart Error Handlers do with this information below.) Chained Find I had to shift platforms to avoid a broken arrow in Figure 6.) Offset and Sparse Enums Of course, not all the errors you'd like to report come directly from a
For example, enter 5008. A glance at the block diagram (Figure 12) will show that the Vendor Error number, the Error Name, and the singular form of the VI's name are all combined with the Figure 13: Smart General Error Handler Diagram Figure 14: Adding Device Errors Figure 15: Overlapping Errors Those Extra Explanations Recall that Chained Find First Error allowed for additional explanations that appeared Add Comments 1 2 3 4 5 My Profile|Privacy|Legal|Contact NI© National Instruments Corporation.
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://www.labviewing.com/custom-error-handling-in-labview/ Run the VI. Cart|Help You are here:NI Home > Support > Manuals > LabVIEW 2011 Help Defining Custom Error Codes »Table of Contents LabVIEW 2011 Help Edition Date: June 2011 Part Number: You also can define custom error codes in the same range by creating an XML-based text file.
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? http://edsdefence.com/labview-error/labview-error-codes-2011.php Select the Sort Error Codes button to sort the error codes in ascending order. Even though the error cluster and the error wire are some of the most widely recognized features of LabVIEW, they are quite frankly also all too often shrouded in misconception, inevitably National Instruments recommends that you use the General Error Handler VI to define custom error codes in the range of 5000 through 9999 and -8999 through -8000.
When you use someones DLL, wouldnt it be nice to be able to convert the (typically negative) C error codes to the LabVIEW User Error Code rangeand lift the C comments If existing is clicked, user will be prompted to select a file.Then error code editor will be loaded with all user defined errors defined in that file. Different projects use different equipment. http://edsdefence.com/labview-error/labview-error-codes-list.php But how should we keep track of which error numbers we've used, and which we haven't and how do we make a summary of all the errors we've defined?
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. Try it out.

To understand the package, we must start with the basic components and build up to the full structure. I have seen a lot of .dll driver type calls that return undefined numbers, frequently in the lower range.
An error dialog appears and displays the customized error code and description. What I would like would be the option to have a per-project user error table (hey, we have a project explorer now :thumbup: ). Right-click the error in input and select Create»Constant from the shortcut menu. this content We can customize error code messages and also create new error codes as user defined error codes.
Figure 7: Setting Error with a Selector (If you're not following the directions to ignore Chained Find First Error.vi, you may have noticed that it's grown red dots.

[Edited] LV_Pro Trusted Enthusiast 08-05-2010 09:07 AM - edited 08-05-2010 Wouldnt it be nice if these enums could contain a few errors, e.g., file not found or timeout, with the error codes that NI assigns?

You must save the error codes file in the format xxx-errors.txt, where xxx is a name that you supply. Have you agonized over interrupting the program flow rather than just passing the information to a higher level, especially if your code is to be incorporated in some else's?

This could mean Python crashed or an incorrect Session ID was supplied, or that Python is busy with another operation and the call timed out. 403424 - Unsupported data type¶ An
Using this feature each application can programmatically set all its own error code descriptions when it initializes for instance. Organization While the order listed above might be a good one for developing or expressing a wish list, explaining the package in that order will lead to considerable confusion.
