Connecting Offset Enums to the Error Cluster Chain As mentioned above, the offset error enums need Variant to Error Code.vi to be really useful, but you will rarely if ever use Error Analysis The Old Smart Error Handlers Smart Simple Error Handler.vi and Smart General Error Handler.vi are of the same vintage as Chained Find First Error.vi. I never liked those guys. This is a perfect application for an enumerated type def., but we'd like an enumerated variable whose values are in the User Error Range and not simply a continuous positive progression http://jamisonsoftware.com/general-error/general-error-handler.php
In fact, if customized, detailed, individual comments were used religiously, only a single, generic error with no explanation at all would be perfectly suitable. 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 How about having these enums start at some code in the user error range (5000-9999)? An array appears.
The first column lists the error codes defined by the vendor. Veröffentlicht am 07.03.2013In this episode, we see how to conditionally execute code based on an error. Du kannst diese Einstellung unten ändern.
Sometimes, as in the case shown in Figure 3, only part of the information is available and you must fill in the rest by hand.

If error in indicates an error, the VI ignores error code. error in describes error conditions that occur before this node runs. Wenn du bei YouTube angemeldet bist, kannst du dieses Video zu einer Playlist hinzufügen. Die Bewertungsfunktion ist nach Ausleihen des Videos verfügbar.

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?

The worst thing about the LabVIEW 1 or 2-button dialogs is they use the root loop, so while displayed, many functions such as Open VI Reference just have to wait their The default is 0.

A LabVIEW Error-Handling Introduction Overview Have you ever wished that LabVIEW treated your custom errors like the built-ins, with full call chain information and likely causes listed in the error dialogs? Switch to the VI in which you defined your custom error code, and run the VI again. Your cache administrator is webmaster.
