PHPUnit : Fatal error handling
Hi all, I use PHPUnit for unit tests, but when a fatal error is triggered, the script dies and I have no correct PHPUnit output. I'd like that the PHPUnit output stays correctly formated, because it is read by a plugin for Eclipse. Actually the fatal error stops PHPUnit and in Eclipse the plugin can't interpret anything (because the PH...

Creating a new directory structure and moving files using APS.NET and C#
Can someone tell me what is going to happen in this code when an error is encountered? Ideally it should continue the foreach statement until it gets to the last record, but I suspect it's stopping in the middle of the operation because when I check the number of files moved it's off by 225. If it is in fact stopping because of an error,...
TypeLoadException hiding inner exception
Hi I'm using Compact Framework 3.5 / VS2008. I'm getting really odd behavior with TypeLoadException. The following code throws this error. The reason is a problem with the database connection.

How do you handle validation severity in Silverlight 4?
With 4.0, Silverlight now supports INotifyDataErrorInfo but out of the box I can't seem to find anyway of specifying a severity (Error, Warning, Info) in order to be able to style the inputs differently (red, yellow, blue). How do you handle this? Is there anyway to tap into the mechanism that styles the inputs, or do you have to resort...
MVC HandleError vs customErrors tag
So if I understand [HandleError] correctly (see here) you have to add it to each Controller that you want to have errors handled on. It seems much easier to just add the path of your error page into the web.config customErrors tag: <customErrors mode="On" defaultRedirect="~/Error/Index" > </customErrors> In what situations would usi...

What non-NULL memory addresses are free to be used as error values in C?
I need to write my own memory allocation functions for the GMP library, since the default functions call abort() and leave no way I can think of to restore program flow after that occurs (I have calls to mpz_init all over the place, and how to handle the failure changes based upon what happened around that call). However, the documentati...
