You either had to have a different Smart General Error Handler for each project or a single very comprehensive one. on Check box in Multicolumn Listboxdeepu on Table with Drop Down Menu in LabVIEWlvgeek on Timer : Measuring Elapsed TimeJohn on Timer : Measuring Elapsed TimeAarthi on Timer : Measuring Elapsed weblink
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 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. Coding can be difficult at times and refurbished/recycled code that works is nice to have, therefore helping others is always welcomed. Here's why!) Figure 17: Using an Offset Enum to Ignore an Error Another Demo Error Analysis Demo.vi demonstrates the various capabilities of the Smart Error Handlers.

My workaround has been to use VIPM to create a package and deploy it with the installer.
During program initialization, you merely wire any additional error tables you need to it (Figure 14). 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 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.

The text table is fine for the human interface, but the computer prefers different formats. Does anyone have any suggestions on where to go from here? Sometimes, as in this case, the vendor's error descriptions can be extracted from a C header file with the aid of the utility Extract C Comment.vi. http://www.labviewing.com/custom-error-handling-in-labview/ The second column lists the codes from the user error range (5000-9999) that you wish to assign in place of those defined by the vendor.
Read more ... Add the General Error Handler VI to the block diagram. 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. 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?
In fact, if customized, detailed, individual comments were used religiously, only a single, generic error with no explanation at all would be perfectly suitable. http://stackoverflow.com/questions/11966399/stop-warning-dialog-from-appearing-with-custom-error-codes-labview I don't much want to roll my own solution to error code storage when LabVIEW has something perfectly capable built in! 3 commentsshareall 3 commentssorted by: besttopnewcontroversialoldrandomq&alive (beta)[–]iYogurtCLA 1 point2 points3 points 2 years Watch Queue Queue __count__/__total__ Find out whyClose FREE LabVIEW Core 3 Training Lesson 4 (9 of 9) Nestor Ceron SubscribeSubscribedUnsubscribe1,5081K Loading...

Sounds like a great Wish List item. Following is the error file created, Errors will be handled by using existing [simple error handler or general error handler] vi’s , no need of any extra code. Loading... check over here Notice that the message text box on the front panel of the General Error Handler VI displays the same customized error code and description as the error dialog.
Don't be concerned that mixing enums and integers will slow things down.

In some cases, I'll use string manipulations and bundle the string into the error cluster to (for example) identify which stepper motor had the drive fault. 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? When building application take care to add custom error code file in always included file list. The previous section will give you a reference for determining where the different structures, VIs, and controls fit in the overall picture.
These errors will not be understandable for the end user of application. In addition, you needed to duplicate this information in separate tables for each device for which you were going to convert vendor errors to the User Error range. What are pros and cons of this? this content Loading...
An error dialog appears and displays the customized error code and description. LabVIEW version: 2012 and newer.Installer: VIPM.Dependencies: None. But I am lacking a useful method to keep an order in the different error codes. 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?
