Hello I am using the cElementTree library to parse XML files in Python. Everything is working fine But I would like to provide full error messages for the user when a value in the XML is not correct. For example, let's suppose I have the following XML: <A name="xxxx" href="yyyy"/> and want to tell the user if the href attribute doe...
I have imported a tab-delimited text file in an Access database on a button click event. The file is properly imported, the issue comes if the user selects a text file of different format, the code will import the improper data into the database and creates a new ErrorLog table. How do I restrict improper data from table? How to do err...
This is very straightforward: I have 4 packages, and I would like to define one Error handler for all of them. I already created OnError event handler in one package and now I would like to configure other 3 packages to use the same error handling routine. I don't want to copy and paste. What is the easiest way of doing it? ...
NAnt has two built-in properties, nant.onsuccess and nant.onfailure, for specifying tasks to run on success and failure respectively. Is there an equivalent in Ant? ...
I'm trying to understand the meaning of the value returned by [NSData writeToFile:options:error:]. The method returns a BOOL, which according to Apple's documentation is "YES if the operation succeeds, otherwise NO." Fair enough, but if it's NO, I would have assumed that the error parameter would then be set to some retrievable NSError*...
I have this form in my site that uses JavaScript to clear the fields when clicked on (highlighted) and also checks to see if all the fields have been filled in. I've used this code for other sites and it works fine. I can't figure out why it doesn't work now! Everything is the same from the previous code! ...
While searching SO for approaches to error handling related to business rule validation , all I encounter are examples of structured exception handling. MSDN and many other reputable development resources are very clear that exceptions are not to be used to handle routine error cases. They are only to be used for exceptional circumstan...
I'm currently using a very simple MVC framework, Bear Bibeault's Front Man, which, for those not familiar, is pretty similar to Spring MVC (in concept at least). One of the issues I'm having is how to handle exceptions properly. I am currently doing something like this, try { //do something }catch (Exception ex) { logger.error(...
In my vb.net application if I have a known set of Error Strings i.e. Failed because I don't know about it Failed because I know about it but I can't find it Failed for another reason etc And I get a response which I want to ensure doesn't have the error string in it If returnedString.equals("Failed because I don't know about it")...
I'm trying to parse a CSV file using Python's csv module (specifically, the DictReader class). Is there a Pythonic way to detect empty or missing fields and throw an error? Here's a sample file using the following headers: NAME, LABEL, VALUE foo,bar,baz yes,no x,y,z When parsing, I'd like the second line to throw an error since it's...
I'm having some trouble with certain input areas of my program. There are a few parts where the user inputs a specific integer. Even if they enter the wrong one that's all fine and dandy, but I noticed if they enter anything not of integer type like 'm' then it will loop the error message repeatedly. I have a couple functions that have ...
Please tell me if this is correct. In my error handler, I need to be able to detect when the @ error-control operator was used to suppress errors, because some external libraries (sadly) use it a lot. Execution of the script should continue, just like when you don't use custom error handlers. When the at-sign is used, PHP temporarily se...
Hi, I've been doing some research on how to globally handle errors in my ASP.NET application. Can anyone suggest me a customizable error handling component to handle all .NET exception globally and log them in database(SQL, Oracle) and also send notification via mail/RSS feed. Thanks ...
I've begun using ASPUnit to unit test my classic ASP code. This is all good and I'm happy. The only problem is with the error messages it displays when a test generates a runtime error. For example, if I've not defined a variable somewhere in my function I get the error: Microsoft VBScript runtime error (500): Variable is undefined W...
From this question, I'm now doing error handling one level down. That is, I call a function which calls another larger function, and I want where it failed in that larger function, not in the smaller function. Specific example. Code is: import sys, os def workerFunc(): return 4/0 def runTest(): try: print workerFunc() ...
I am using JDK1.6_14. This is a generic question though. When to go for error handling and when to go for exception handling? For example, when I carry a division operation out, I can either check if the denominator is zero and throw an error or just handle ArithmeticException. But when to go for which method? Thanks. ...

I am just starting out with Grails, obviously. I've created my domain class and controller, added my own logic to the controller, and everything is working properly -- as long as nothing goes wrong. My custom controller action looks like this: def create = { try { // Get the parameters. def uid=params["uid"] ...
