If a file system task such as a rename fails, for example if the file does not exist, then this is considered an error by SSIS. This means the whole package fails. I can get around it by using a script task, or setting the maximum errors for the package to more than one. The problem with setting maximum errors for the package to more tha...
When writing code in JScript, as I am wont to do as I have never been a fan of ASP.Net and Jscript is infinitely more elegant than VBScript, you can call upon the arguments collection. This is extremely useful to pass into error handlers as you can then output messages to development teams which tell them exactly what the state of the ap...
Hi, I'd like to use constants as config variables within my PHP applications, only when an constant doesn't exist (for whatever reason) it throws me an notice but i'd like that to be a error (or exception) just like when i try to echo a not existing variable. Is that possible without using a seperate function for getting constant value...

I can not change the virtual directory path for the new app, as I have users which have bookmarked different links to the old app. Lets say I have a user, who has this bookmark: http://server/webapp/oldpage.aspx?data=somedata My new app is going to reside ...

I have a another ASP.Net web project that I am working and I have approached error handling from different angles. I was just wondering if any seasoned and experienced developers out there had any recommendations. Bonus points for discussions on a nice logging framework for ASP.net:) ...
I am using this line to obtain and save an image from a URL. file_put_contents("./images/".$pk.".jpg", file_get_contents($PIC_URL)) I am unsure what the best way to deal with an error is. At the moment it is failing because there is no permission, which will be remedied shortly, but I would like it to be able to deal with situations w...
I am having problems using the [HandleError] attribute on my Controller Actions - it doesn't seem to work at all (i.e. it doesn't matter if the filter is there or not - I get the same results...). When an Exception is thrown, I get the standard red-toned Server Error in '/' Application error page instead of my custom view. I have found ...
I am facing the dreaded "Unhandled Exception" raised by Flup. The sad part is its raised at the webserver (lighttpd+flup) level and not at the application level(Django). So no 500 email is raised about where the problem is. Our entire team struggled hard to cleanup the codebase, incase of any ambigous imports and someones of that sort,...

I have 2 options: wrap the cast in try/catch ... handle FormatException...
I am a bit of a newbie when it comes to windows client programming. I have a background worker that has a DoWork event and a RunCompleted event wired up. If an exception gets thrown in DoWork, I want to make changes to my UI, however, I cant because it is in a different thread. I can communicate the error to RunCompleted, but that doesn'...
For my current web development project I'm implementing a back end system that will flag errors and send an email to the administrator automatically with details about what occurred. Trapping the error and generating the email with appropriate error information is pretty straight forward; but a problem arises when one considers certain g...
I have a huge file with lots of links to files of various types to download. Each line is one download command like: wget 'URL1' wget 'URL2' ... and there are thousands of those. Unfortunately some URLs look really ugly, like for example: http://www.cepa.org.gh/archives/research-working-papers/WTO4%20(1)-charles.doc It opens OK in a...

Here’s the scenario: You load a page, which renders based on the data in the database (call these the “assumptions”) Someone changes the assumptions You submit your page ERROR! The general pattern to solve this problem is this (right?): In your save proc, inside a begin and commit transaction, you validate your assumptions first. ...

In that function, I want to check if the $email is already present in the database. It will return 'true', if exists. Else 'false'. Now, the query execution can also fail, In that time I want to report 'Internal Er...
I want to catch exceptions in javascript if an insertion query is not done.
