ranges. You can, however, define custom error codes using the following ranges: -8999 through -8000 5000 through 9999 500,000 through 599,999 You can define custom error codes in the following ways: To create multiple error codes for use throughout your application and distribute them in built applications or shared libraries, use the Error Code Editor dialog box. To create custom error codes that do not need to be widely used in your application or distributed in built applications or shared libraries, use the General Error Handler VI. To create a single custom error code for one particular instance in your application, use the Error Ring. YourFeedback! Poor|Excellent Yes No Document Quality? Answered Your Question?

Say I have a toplvl VI called Caller.vi which calls Sub.vi. The toplvl vi whishes to use the Sub.vi's error out cluster to determine what to https://forums.ni.com/t5/LabVIEW/Best-way-to-throw-custom-error-from-SubVI/td-p/1332790 do - e.g. halt execution of the toplvl vi if the Sub.vi throws an error. Easy enough if the Sub.vi just have to pass errors from build in LabView functions and VI's, but how to do it if the sub vi has to throw a custom error upon some condition? Say the sub vi takes a certain number of inputs and that the inputs need validation before executing what ever the sub vi does. E.g. a certain algorithm implemented is only meaningfull if a>10. My own thought is this: Simply select between an empty/no-error error cluster and an error-cluster containing the wanted custom errorcode and description. The area circled in blue is the interesting part: Is that the worst idea you've iever seen implemented? The only other real suggestion I've been able to find (which originally adresses another issue, but shows a method for "throwing an error") is a VI posted in this thread: http://forums.ni.com/t5/LabVIEW/Throw-an-error/m-p/882575 which looks like: Please help me out guys How to throw a custom error which is not intended for the end-user, but intended to ease the life of a develper calling the sub-vi

How can I do this?
insert more detailed information at individual error sites and have that information appear in the dialog so you wouldnt have to pop up an additional dialog box to help the puzzled user? Would you like to be able to specify your error with an intelligible enumerated constant rather than trying to remember which error code you assigned to which type of error? How about having these enums start at some code in the user error range (5000-9999)? 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? Different projects use different equipment. 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? 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. 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 to use as explanations in the LabVIEW error dialogs? 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? All these features are included in the new error-handling package from . They are all compatible with the standard error-handling routines from National Instruments, so they integrate smoothly with your current code. You get to choose which features make sense for each project, or even each part of each project. (Severability! Who said that reading those licensing agreements was a waste of time?) See both the text and figures below (included in their entirety and resized for convenient printing in the downloadable package) and the context sensitive help (ctrl- or cmd-H) for more details. Be sure to try the two Demo VIs as well. 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. To understand the package, we must start with the basic components and build up to the full structure. The previous section will give you a reference for determining where the different structures, VIs, and controls fit in the overall picture. The Error Data Bases Perhaps the most intelligible starting point is one (or a sampling) of the
