Help converting a project from C# to VB.Net

I found this really interesting article online about using page templates.  I am very interested in trying it out.  I have two problems:

1.  The code is in C# and I only know VB.Net
2.  The code is a bit beyond my expertise!

I have converted a good bit of it using a combination of common sense and online converters.  However, I am still having some problems with the default.aspx page and there are some instances where I am getting errors with the "request" method.  

The biggest help to me would be if someone could provide a general explanation of what the code is doing.  The article is too detailed for my knowledge!  Any help at all would be greatly appreciated.  The article can be found at:
