User defined Error Codes

Hello,
I am using the "Bundle by Name" VI to insert error info into the Labview Error Cluster. I am doing calculations and have assigned a -23096 to the error code and during program execution a dialog box pops up stating the following
Possible reason(s):
Analysis: Too many decimal points.
I am assuming the dialog box is being generated by the system because the -23096 is defined to in the the range for Math errors. So how do I defined my own error codes that Labview will not use and cause unexpected dialog boxes to appear. My approach to handing the errors is the I will check the error status flag and if the error is one of mine I will handle it.

Kaspar

After rereading your last post I think I know what you are getting at. Here is how I create a custom error cluster.
1.On your front panel lay down a "error in" control cluster found in 8.2.1 at Array Matrix and Cluster.
2.Switch to your block diagram and right click this control and change it to a constant.
3.Wire this constant into the top of a bundle by name function. Expand the bundle by name to show the 3 elements. For each element create a constant and enter your information. You can feed the output of this function to any error input of the following vi's or create an indicator and hook it to your front panel connector pane.
Hope this helps

Is there a LabView example in the use of user defined error codes?

Specifically, I have a VI that tests four arrays of data against various high/low limits. I have pass/fail outputs for 18 tests. I'd like to combine these into an 'error out' cluster with appropriate error codes and messages, for which I've created an x-errors.txt file.
My first question must be trival - how do I just set the 'status' bit of the error stream to let the general error handler then look up the error desription from the file?
Secondly - I can't find an example of this in the technical resourses, amI missing something?
Thanks,
Mike

There is no example program. There is extensive help on how to do this. Here's the basics.
1) There are two ways to define user error codes in LV6.1. If you are using LV6.0 or earlier, only one method is possible.
2) The 6.0 method involves wiring arrays of error codes and arrays of error code strings to the General Error Handler.vi. These codes will be used to explain any error code which is undefined in LV's internal error code database. Error codes reserved for users which are guaranteed not to be used by NI are from 5000 to 9999.
3) The 6.1 method allows you to create a specially formatted error code file on disk that will be merged with the LV error code database each time LabVIEW launches. For help on this, go to LV's online help, and in t
he Index tab, type
"user-defined error codes, in text files"
(without the quote marks)
4) If you want to set an error into the error cluster, use the General Error Handler.vi again. Wire your error code value to the Error Code terminal (the leftmost-topmost corner terminal). Wire the name of your VI to the Error Source terminal, and wire "No Dialog" to the Type of Dialog terminal (left-side, near the bottom). The error code cluster that comes out of this VI will either be the error in (if one was set) or a new error code cluster with your error and the status bit set to TRUE.
5) The attached demo is written in LV6.0.

Is there a range of error codes reserved for user defined error codes?

I would like to create my own error codes for a CVI dll but I want to make sure I don't use error codes already defined for something else. Is there a range reserved for such use?
Samee thing for warnings (errorcode > 0)
Thanks

I have never found a positive mention of a "safe" range of error codes available for user-defined error conditions, but I can suggest you some source of informations.
First of all, every library has its specific list of error codes, usually listed in the relative include file. All these error codes are listed in the online help too (search for "error codes" in the index tab of the help).
Second, GetGeneralErrorString () is a function that can be used to trap errors of the following libraries with a unique error function:
User Interface Library
Easy I/O instrument driver
Toolbox instrument driver
ActiveX Library
DIAdem Connectivity Library
.NET Library
DataSocket instrument driver
Network Variable Library
Real-Time Utility Library
TDM Streaming Library
UDP Support Library
This means that the error codes from this libraries do not overlap, so you could derive from its code some ranges not used by these libraries.
Nevertheless, there is not a single function for error trapping: every library has its proper list of error codes and a function to decode them in human readable form, andthere is no guarantee that these ranges does not overlap. It's up to you to trap errors from every function in the proper way.
Proud to use LW/CVI from 3.1 on.

Custom user defined error codes

Does TestStand use my custom defined error code file that I created in LabVIEW. It is in XML format and works fine with LabVIEW but does not seem to be picked up by TestStand. Do I need to configure this?

Matt -
Turns out that it does work if your error file is located in the proper location.
The TestStand adapter internally uses the LabVIEW Runtime engine so it expects additional language files under
C:\Program Files\National Instruments\Shared\LabVIEW Run-Time\7.1\Errors\English\.
The LabVIEW development environment expects the additional language files under C:\Program Files\National Instruments\LabVIEW 7.1\user.lib\errors\. I think this will be used when running a LabVIEW application, like an OI, that uses TestStand.
In general NI software places its error files under C:\Program Files\National Instruments\Shared\errors\English\. I do not recommend this location, but if anything is added to it, I think LabVIEW and the RT woul
d picked it up.

How do you use user defined error messages in Value Help?

Hi,
I'm currently working on a Modifiable Value Help Selector in Web Dynpro Java, and I want to use a user defined error message when I validate the values entered by a user. Currently, it's returning its default error message ("Character <string> does not match...").
Since the project requires a different error message, is there a way to override the default error message and use my defined error message instead?
Thanks!

Hi Angelo,
I am not sure why message area is showing both Custom and inbuilt messages but you can try the following:
i guess you must be using reportContextAttribute exception for showing Error messages on the input fields as well.in that case you can disable the message area so messages will appear only on the Context level ie; on input fields.
For other messages apart from validation messages you can enable the message area before reporting the exception.
make sure the boolean context variable which will be used for enabling and disabling the message area should have Readonly property set as true.
I am not sure whether this is the only solution for this but you can try and see if it works.

Page process: user defined error-message

hi to everyone!
i want to display a user-defined error-message, if for example a select in an anonymous PL/SQL block returns more than one row. i tried it with an user defined exception, but i get allways the success message... how can i do that?
thanks for your help.
bye,

Hi,
In the exception handler of your PL/SQL process use this :-
apex_application.g_print_success_message := '<span style="color:red">Error message</span>';Regards

[Problem] Define Error Codes in web.xml

Hi everybody!
What I want to do is very simple to explain:
For our web-application I have designed a global error pages, that should appear, whenever an error occurs. Not matter if it is an 500 a 404 or a 202. Always the same page, that does the processing of the error in the background.
In the web-xml if defined it like this: (for example for a 500 error)
<error-page>
<error-code>500</error-code>
<location>/global_error_page.jsp</location>
</error-page>Now I want to alter the web.xml in a way, that this error page is called for all possible error-codes, without writing a whole block for each error-code.
For some reason <error-code>*</error-code> does not work.
And ideas, suggestions?
Thanks in Advance!
Stef

i have done it for collecting Database errors but not successful in doing it for Catch errors.
The way to do it for DB errors is to return error through pragma and in try itself store it in a String and use requestDispatcher by setting attribute and getting the same in JSP. But this should be inside try to work.
For Java errors i have defined error code in web.xml
so the possible java errors shows the error page.

User defined error handling in PLSQL procedure of portal form

I need some help of building a user defined exception handling in PLSQL.
I build a portal form based on a PLSQL procedure.
In this procedure there are several SQL statements with exception handling.
In case of exception I want to display my on error message and than raise the procedure, so that the user can read the message and than go back to form.
I try this by calling a raise statement generating some HTML output over htp.p() but than the output look's like
SQL:
begin
"ACHEMA2003"."P_LOGIN" ( P_STAMM_SEQ => 33491, P_ADRESSNR => 2009721, P_PASSWORD => '3333', P_PROJEKT_ID => 'ACHEMA2003', P_MESSENR => '00023', P_SPKZ => 'D');
end;
ORA-20000:
Login ACHEMA 2003
Ung|ltiges Passwort !!!
Back to form
I want to supress the standard Oracle messages.
Now I read about the packages wwerr_api_error and wwerr_api_error_ui to make this, but it seems to be a little difficult.
Is there anybody who have a solution for this problem, perhaps some example PLSQL code for this.
Thanks Erwin.

Jacob,
Try following:
declare
v_sender VARCHAR2(1000);
v_sender_id NUMBER;
begin
v_sender := p_session.get_value_as_VARCHAR2(
p_block_name => 'DEFAULT',
p_attribute_name => 'A_SENDER');
v_sender_id := p_session.get_value_as_NUMBER(
p_block_name => 'DEFAULT',
p_attribute_name => 'A_SENDER_ID');
insert into hd (number, text) values (hd_seq.nextval,
'step 3 v_sender = ' || v_sender ||
' v_sender_id = ' || v_sender_id);
if v_sender_id >= 100 then
p_session.set_value(
p_block_name => "_block",
p_attribute_name => '_STATUS',
p_value => 'Sender ID must be less than 100!');
-- return to your form with status message set
-- and all fields filled with recent values
return;
end if;
end;
-- This point is reached only if validation is OK
doInsert;

Can I change the location of my user-defined error file to the project directory?

The LabVIEW help says that the user-defined (XML-based) error file has to be located in the labview\user.lib\errors directory.
I would rather have the file in my Project Folders directory, as this is what is distributed.
Is there a way to make LabVIEW look elsewhere on startup.
-James

Hey, from the LabVIEW help, it looks like you don't need to worry about it.
"If you use the Application Builder to create an installer, you can place a checkmark in the Install custom error code files? checkbox on the Advanced page of the Installer Properties dialog box to include LabVIEW error code files. 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\8.2\errors directory."
If you select that checkbox, LabVIEW takes care of it for you.
Hope this helps!

Throw user defined Errors from within built in apex procedures

Hi all
The task at hand is I have a tabular form with add row button. On click of this button, the built in add row to a form type of process is called. The table in which this row is being added has some Foriegn key constraints and some other check constraints.
What I want is if during insertion in the table, if there is a foreign key voilation and the process fails, I should be able to throw a user defined exception.
And moreso, I want to throw this in the notification area and not the error page.
Any thoughts??
Regards
Shantanu Dhanuka

Hi Shantanu,
If you want to capture exceptions raised by the wizard created MR* processes, you have to complete replace this processes with your own processes where you do the insert/update/delete. Don't forget to add the code for the optimistic locking.
About showing the error in the notification area, see my blog posting at
http://inside-apex.blogspot.com/2006/12/hacking-apex-error-page.html
which is able to do that.

User defined error in register service of service portlet

Hi,
When I try to install the service portlet(PLSQL PDK)
I get a user defined exception error whenthe service register
sql file is ran.
Does any one know the solution for this??
cheers,
Ranjit
PS:sorry for posting this second time.

Hello Shanky!
            When ever purchase order is created, a message type will get invoked which in turn will call the function module IDOC_INPUT_PORDCR1.The import parameters of this function module must be populated with appropriate values when purchase order is created.Failing which, error messages will be generated.That's what happened in your case.
           Also, please check in WE05 whether your IDoc is created with error.If you have erroneous IDoc in WE05 for your purchase order, it should be due to the above stated reason.To override the erroneous IDocs , take a copy of the above function module and do the customization that suits to your requirement.
           If you cannot handle this issue, approach your ABAP-XI consultant or the ABAPer who has knowledge in ALE/IDocs.

Will ASE system defined error number fall into user defined error numbers starting from 20000?

The maximum error number in sysmessages:
select max(error) from master.dbo.sysmessages
ON ASE 15.0.3
column1
19975
ON ASE 15.7
select max(error) from master.dbo.sysmessages
column1
19999

Hi Siddhartha,
I don't expect ASE to start using error numbers in the user-defined range. I'm part of the group that reviews new messages, and conserving the shrinking pool of available numbers is certainly a concern of ours. We are actually still some ways away from running out of numbers.
The error numbers are actually a concatenation of a major family number (the 100s values)
and minor numbers 0-99 in each family. There are many families of errors that have unused values, one possibility is that we could use those unused values for errors that don't really belong in that family.   Another thing we can do (though it would have to be in a major release of both open client and ASE) would be to introduce another mechanism that might work just the same as error messages but be called, say, "notifications" or "faults' (though that term is already used by checkstorage.
There actually already exist two such families of messages, one called "errors" and the other called "messages". You can see this when configuring a shared memory dump, both are possible dump conditions. "Errors" show up in the errorlog displaying the message number, severity, and a state value, while "Messages" just display text and support has to look up the associated message number in the ASE sourcecode. (Not all text messages in the log are actual messages like this, some are just text that gets printed that one can't configure a memory dump on.)

Getting error when run user defined transaction code

Hi there,
I created one ZTcode by using standard Tcode's program and screen number. When I run this Ztcode, shows an error "Error when access file TC10 Ztcode" on taskbar. What is problem, pls reply.
ur answer is most useful.
Regards,
Zakir Khan.

TC10 stores information related to SAP transaction like TC10-TRTYP which give the type of transaction (display, edit, initial)
The standard program check in this table (and other TC*) how it should perform.
Way to solve the problem
- try defining you Z-transaction by referencing standard transaction, not giving the program/dynpro.
- If that don't work you may have to duplicate the called program and then override sy-tcode by the original value in the program before accessing tables TC*
- Other way is to duplicate records in table TC10 and other tables
Regards
