  • If you name your VI 'Simple Error Handler.vi' or 'General Error Handler.vi' as its file name, then the auto error handling dialog won't come up.

• Ranges of Error Codes
• General LabVIEW Error Codes
• Defining Custom Error Codes

→ Use the range reserved for user-defined errors (500000 – 599999).

Where Are LabVIEW Error Code Files Located?

The Error Code File Editor (Tools→Advanced→Edit Error Codes) provides a simple GUI for creating and editing a custom error XML files. See https://labviewwiki.org/wiki/Error_Codes_Editor for details.

If you are creating a stand-alone application (EXE), refer to the Distributing Custom Error Codes in Text Files topic in the LabVIEW Help. The installer build includes all error code files from <LabVIEW>\project\errors and <LabVIEW>\user.lib\errors and installs them in the <Shared>\LabVIEW Run-Time\X.X\errors directory.
