A common problem when doing value comparison inside of Javascript is the automatic type conversion that happens for you, this means all the following statements resolve to “true”. 1 == 1; 1 == ‘1’; 1 == “1”; As a little bonus snippet in a post by Steve Wellens he provides an answer to the problem,…
As part of my current project, I’ve spent some time over the past couple of months trying to determine the best (cheapest) SQL Server configuration to support web servers running in a virtualised environment. As a quick disclaimer, the following are my thoughts on the subject and should be used as guidance for further research…
One of the most commonly encountered issues when developing websites that must support both HTTP and HTTPS pages is the warning that a secure page “contains both secure and unsecured content”. In a nutshell, this is when a page that is being displayed via the HTTPS protocol contains one or more references to additional resources…
It looks like the recent Microsoft updates broke ASP.NET / IIS on my development machine. Trying to launch any website hosted on my local IIS server returned a 500 error and the following error message: Calling LoadLibraryEx on ISAPI filter “C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_filter.dll” failed; And checking the event log just returned a similar error message: ISAPI Filter…
I’ve just spent a good couple of hours trying to debug what appeared to be a corrupt session in NHibernate. The unit tests would work, isolating the NHibernate code causing the problem worked, but within the application when calling Session.Save() the code always complained about a corrupt session. Finally, after much investigation and head-scratching, the…
The following SQL contains a subtle bug that will always result in the text “No Rows Affected” being output. [code language=”sql”] SELECT ‘Hard Coded Row’ IF(@@ERROR <> 0) Print ‘Error Occured’ ELSE IF(@@ROWCOUNT = 0) Print ‘No Rows Affected’ [/code] The error occurs because the reference to @@ERROR in the first “IF” statement counts as…
Over the weekend I went along to the fantastic DeveloperDeveloperDeveloper day held at Microsoft up in Reading. The quality of the presentations was fantastic and even for frameworks/subjects I was familiar with I learnt loads. For me, the most useful presentation came at the end of the day (just as the brain was beginning to…
By default objects mocked using MOQ will handle calls to method/properties that have not been defined, which 99% of the time will be the desired behaviour. Occasionally however a situation will require that MOQ throws an exception when accessing an undefined method or property. The MOQ framework provides this functionality via the MockBehavior enum but…
I recently asked this question on Stack Overflow. I was using reflection and MethodInfo to confirm that a controller contained an action with the required method parameters. If one was found, this would then allow my code to unit test that the correct Action Filter Attributes were being assigned to the controller action (so a…
UPDATE: Since putting this article together MS have released their VS2010 and MSDN Licensing White Paper, which whilst it confirms all of the following should be used in preference to this information. Original Article: Firstly, a bit of a disclaimer – the following are just my observations/opinions only and should not be used to plan…
