Value does not fall within the expected range
Ugh…Chances are if you are reading this you’ve been frustrated with SharePoint at one point or another. The “Value does not fall within the expected range” error message has plagued me ever since I started working with SharePoint. Usually this error comes up when I’m in a publishing site that has been backed up from our development environment and restored into a production environment. The actions that throw this error are when the user clicks “Page Settings” from the Page drop down from the page editing toolbar.
In my case the error that’s going on here is that the page layout is not referenced as a relative url and is actually referencing the old server. To fix this issue we just need to loop through each SPWeb and update the page layouts to be relative. A little over a year ago I found a blog post online that had the solution by a very smart man who wrote a command line program to solve the issue. I am unable to find his post online today, so I decided to post my version of the code that I’ve updated to be used in a web part. I’ve compiled this code into a web part and whenever I run into the “Value does not fall within the expected range” error, I drop the web part on the home page, let it run and then delete the part off the page. 99% of time it works every time 
SharePoint Vanity URL Rewriting
During the day I am a software engineer and from time to time I tend to come up with some cool solutions that I think other developers would be interested in. So going forward I will be posting some code that I have built and want to share with all you other nerds out there. Here goes!
Looking around the internet I’ve seen that many people have been trying to implement URL rewriting in a MOSS environment. Ive implemented url redirecting with MOSS using the HTTP module route for a while now and I’ve documented the code I used and what parameters worked the best for me here;
Take a look and let me know if this helps you and if you have any questions.
After messing around for a little bit it, I came up with a good way to do it. When I was looking for examples on the web there were a lot of people saying that it couldn’t be done. But in the end it actually didn’t take much to implement it. Here’s an HttpModule that I wrote to do the work.
The key pieces are the this.app.BeginRequest += new EventHandler(app_BeginRequest) which steps in front of the request and allows the module to get its redirect on. And HttpContext.Current.RewritePath(redirect, false); will push the necessary headers n such forward so that the receiving .aspx page will understand how to correctly post back.
