User Interface Library Error Codes

The User Interface Library routines return negative values when they detect error codes. Some functions, such as LoadPanel, return positive values for a successful completion. The following table lists the error codeserror codes, defined constants, and error messages associated with functions in the LabWindows/CVI User Interface Library.

Use the GetUILErrorString function to convert the error code, returned in the status parameter of User Interface Library functions, into meaningful error messages.

Error codes are defined in the cvi\include\userint.h file.
