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. Wouldnt 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. However, comprehensive treatments of the more advanced topics have been scattered and difficult to find-until now.LabVIEW Advanced Programming Techniques offers in-depth coverage of the subjects that move you to the next It has been fixed in the current version.) 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. Labview Create Error Message In the Error Code Range drop-down listbox, select Custom Error Code. Your cache administrator is webmaster. My own thought is this: Simply select between an empty/no-error error cluster and an error-cluster containing the wanted custom errorcode and description.
Poor|Excellent Yes No Document Quality? A Select function could then be wired to choose between "no error" and your error of choice depending on some test on your diagram (Figure 7). Double-click the string constant and enter a description in the user-defined description array. Remember that the introduction said that inconvenient features could be left out with impunity.
Blume presents practical guidelines or “rules” for optimizing every facet of your applications: ease of use, efficiency, readability, simplicity, performance, maintainability, and robustness. http://www.labviewing.com/custom-error-handling-in-labview/ Basically you wire an error cluster and "error in" into a Select, switching off of the error conditional. Labview Generate Error Clear errors and warnings more efficiently than with the built-in functions. Figure 2: C Header File In many cases, you will have a C header file or the equivalent from the vendor that contains all the pertinent information other than the LabVIEW
Enter a description in the Error Description (Optional) field. this contact form The LabVIEW code is platform independent, but the DLLs are not.

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.
The first time in any session that one of these error definition VIs is called, it parses the information into forms more useful to the computer (Figure 4). Optionally add custom reason descriptions and timestamp.

Creating a custom error message for an already-defined error code is useful when you want to return the error code for a common error case but you want to provide specific From the size of the scrolling thumb on the table (not the front panel windows thumb), one can tell that only a small portion of the error table is visible. (In Personal preference. Check This Out If there is an error, speed (at the microsecond level) is not a concern; things are already broken.
on Check box in Multicolumn Listboxdeepu on Table with Drop Down Menu in LabVIEWlvgeek on Timer : Measuring Elapsed TimeJohn on Timer : Measuring Elapsed TimeAarthi on Timer : Measuring Elapsed This means you can incorporate some generally useful built-in code directly in your custom error set, as shown in Figure 9. The text table is fine for the human interface, but the computer prefers different formats. For a lesser list, the table can be filled entirely by hand.
A glance at the block diagram (Figure 12) will show that the Vendor Error number, the Error Name, and the singular form of the VI's name are all combined with the Set and clear errors and warnings Set errors and warnings with the proper call chain. Update Error Enum.vi is provided in the package to maintain synchrony between the error definition file and its associated enum or to create the enum in the first place. Once you've trimmed the "status" and "code" elements off of the Bundle By Name, and selected "View as Icon" on the cluster, the end result is concise enough to copy and
Add Comments 1 2 3 4 5 My Profile|Privacy|Legal|Contact NI© National Instruments Corporation. How about being able to set a default error dialog type for the entire sessionand 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.
