Finding Error Code Descriptions

LabVIEW 2013 Help

Edition Date: June 2013

Part Number: 371361K-01

»View Product Info

LabVIEW installs built-in LabVIEW error codes and error codes for related drivers, toolkits, and modules as XML-based text files.

You can use the General Error Handler or Simple Error Handler VIs to obtain a description of these error codes.

  • General Error Handler

  • Simple Error Handler

You also can select Help»Explain Error to display an error code description in the Explain Error dialog box. Enter the error code number in the Code field or, if the error code number is in hexadecimal format, in the Hex Code field. Press the <Enter> key or click anywhere in the dialog box to display a description of the error code in the Explanation field. This description is the same description that appears in this help file. You also can generate error cluster reports to obtain descriptions of built-in error codes.

If the VIs do not return a description, the error code text files might have been moved, deleted, or corrupted. This problem usually occurs when you use user-defined error codes, applications or shared libraries, or drivers released before LabVIEW 6.1.

Undefined Error Codes

Undefined errors can occur for many possible reasons. The following are some suggestions and ideas for ways to identify and handle undefined errors.

  • Undefined errors might occur if a description does not exist for the error code. You can create and define a custom error code yourself. You also can contact National Instruments technical support for assistance with undefined error codes.
  • An undefined error might occur if you wire a number that is not an error code to an error code input.
  • Undefined error codes might occur because the error relates to a third-party object, such as the operating system or ActiveX. For third-party errors, you can search the Web for a description of the undefined error code. You can search with the numerical error code or for the hexadecimal, or hex, representation of the code. For example, you can search for the error code 12341234 or for the hex display of the code, 0xBEEDF00F.
Tip  ActiveX error codes are documented by Microsoft in winerror.h.

Applications or Shared Libraries

If you are developing an application or shared library, you must distribute any relevant error code text files with the application or shared library.

Legacy or Third-Party Drivers

If you are using a driver that was released before LabVIEW 6.1, the driver installed a version of error.llb that contains all the driver error codes. The driver did not install error code text files to describe the driver error codes.

If you installed the legacy driver after installing LabVIEW 6.1, you must replace the driver's version of error.llb with the version of error.llb installed with LabVIEW 6.1 or LabVIEW 7.0.
