Debugging hidden features in SharePoint

Well it’s been a while since I have done a blog entry so I thought I would ease myself back into them with a small post about how to debug a hidden feature.

As everyone knows in SharePoint you have the ability to make a feature hidden which means it doesn’t show up via the UI. This is useful if you don’t want users deactivating or activating a feature in the wrong site etc and making a mess of things. However, to debug these features I until quite recently use to switch the “hidden” attribute back to “false” so I could activate the feature via the UI and attached the debugger to the “w3wp” to see what gremlins were making my code go up in a cloud of smoke. However I learnt the other day about the “Debugger.Launch();” method which enables you to launch a debugger for your code and attach to the relevant process to enabling debugging (see http://msdn.microsoft.com/en-us/library/system.diagnostics.debugger.launch.aspx).


Now all I need to do when I want to debug my hidden feature is add “System.Diagnostics.Debugger.Launch();” at the start of the feature activate or deactivate. Additionally this same technique can be used to debug custom stsadm commands.

Shouldn’t validating a checkbox be easier than this?

  Well it's been a while since I have done a post but with changing jobs recently and life in general getting in the way I just couldn’t seem to find the time. However, now I have a spare five minutes I thought I would fire off a post :) So what's the post about? Validating a checkbox web control. Now I know your reading this thinking that's easy all you need is a custom validator and a event handler in your code behind and job done? Well in most cases yes I would agree with you. However, my latest project (a legacy application) uses code generation to create the vast majority of the ASP.NET pages and user controls. Therefore it’s difficult for me to include anything other than the standard set of ASP.NET validators or something which inherits off the “ BaseValidator ” and get it working correctly in the XSLT templates generating the code. Because of this I decided to create my own validator for the checkbox web control. So how do we get started? Well first off you ne...

X509 certificate encryption fun :-)

Recently I needed to encrypt data on a server and allow a limited number of service accounts the ability to decrypt that data so it was as safe as possible. The approach I took to achieve this was by using a X509 certificate and it's ability to allow you to encrypt information via it's public key and decrypt that information through the private key. The key parts of this approach are: - Create a certificate - Ensure the KeySpec of the certificate is set up correctly to allow for encryption e.g. "KeyExchange" or "None" if you are doing this via PowerShell - Set the security on the private keys so only specific user accounts can access it and decrypt information encrypted via the public key. Step 1 - Create a certificate to use The easiest way to get a quick example going is via PowerShell to create a dummy root certificate and the one we will use for encrypting and decrypting. $rootCert = New-SelfSignedCertificate -CertStoreLocation Cert:\LocalMachine\My -Dns...

SharePoint - Search Service Application (SSA) - Attempted to perform an unauthorized operation

On my current project I needed to adjust and add some search mapping via SharePoint's Central Administration web site. This should have been very straight forward as you have the ability to add managed properties and mappings easily via the UI. However, when I went to save my changes I got the error "The settings could not be saved because of an internal error: Attempted to perform an unauthorized operation". Now this was very confusing as I am administrator on the server and added into all of the correct SharePoint groups. I also tried the same action via PowerShell and got the same error.   After a few hours of research and head scratching I managed to get to the bottom of the problem which is the way my user account had been added as an administrator to the server. In the company I work for to make it easier to manage the administrators on a server a group is created in active directory called " servername_admins ". This group is added to the local administra...
