The fourth (and last) column contains the description of the error that will appear in the error dialog boxes. 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 The first column lists the error codes defined by the vendor. Wouldn’t 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? http://robertwindows.com/labview-error/labview-error-6.html

a certain algorithm implemented is only meaningfull if a>10. When building application take care to add custom error code file in always included file list. After you configure the Error Ring, you can adjust the configuration without returning to the dialog box. As long as it is in the range that NI allows for user defined codes. http://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/creating_user_defined_erro/

A separate VI captures the 38 warning codes for this same device.) Figure 1: Front Panel of Dipix Errors.vi NOTE: For convenience, the download is linked with the Dipix and JDS Examples for the two data sets presented in Figures 1 and 3 above are presented in Figure 8 below. Run the VI.

It is good practice to include the vi name in your error string so that you know which vi created the error. - tbobInventor of the WORM Global 0 Kudos Message All rights reserved.

Accumulating Descriptions Looking at Figure 1, even without the hint of the previous section, it is obvious that the second and fourth columns

You either had to have a different Smart General Error Handler for each project or a single very comprehensive one.

You also can define custom error codes by creating an XML-based text file and adding the error codes and messages to the text file. Using this feature each application can programmatically set all its own error code descriptions when it initializes for instance. For example, you can use error code 7, "File not found." and replace that with a description about the specific file that was not found.

Create new file by clicking new, enter all errors and save in the format as -errors.txt in \user.lib\errors directory.

How about being able to set a default error dialog type for the entire session—and to change it temporarily or permanently at any point in the program? Since the actual errors start at enum value 1, the numerical value needs to be one less than the value at which you want the error codes to start. During program initialization, you merely wire any additional error tables you need to it (Figure 14).

The source string gets convoluted trying to preserve as much information about both errors as possible, but this type of problem should occur only on the developer's bench and you should The data values are stored as text in the columns of the table, making it very easy to lift data from text files such as the header file shown in Figure Notice that the message text box on the front panel of the General Error Handler VI displays the same customized error code and description as the error dialog.
