Here is an interesting article on codeproject about creating “drill through” reports.

WCF One-Way Calls, Callbacks, And Events
Here an article I was reading about some of the new (and from the looks of it… very useful) features of WCF.
ASP.NET AJAX Errors
I have been getting a few errors when trying to use the asp.net ajax framework.
The one error message is:
Error: Sys.ArgumentTypeException: Object of type ‘Sys_Application’ cannot be converted to type ‘Sys._Application’/
Parameter name: instance
This is caused by having SmartNavigation turned on for the page.
The other error I was getting was this Sys.ArgumentOutOfRangeException. Value must be an integer. Parameter name: X. Actual value was NaN.
This error is caused by using a “yes” or “no” for “frameborder” for a frame.
Yes and No are valid entries but the framework is expecting a “1” or a “0”.
ASP.NET Upload Component
I think I saw this ABCUpload .Net tool being used by microsoft on one of their internal support sites for uploading large files.
I don’t think it actually gets around the httprequest length and executiontimeout problems, but it does provide you a window showing your progress, which is nice.
Escaping Characters in MailTo
I have recently needed to create some more complex mailto links than people normally use. I need to populate the subject and body with text that is pulled from a DB, so there are lots of random characters in there like @, #, &, -, _, etc…
Most of these won’t work, and need to be escaped.
The most effective way I found was to use the ascii HEX code in this format:
%2D = “-”
%45 = “E”
ASP.NET Process Recycling Too Often
I’m not going to write too much about this, but we have been seeing a LOT of recycles of our web application, which makes us lose session for everyone logged it.
I am just going to archive a few links I have been using to track down this problem.
ScottGu has some reflection code to get the reason the process is shutting down that I converted to vb.net
And here are some places discussing the issue:

This article shows a open source neural network component that the author uses for verification of written characters.
Controlling Programs Remotely
It looks like from this article that the author is showing how to use remoting to interact with a windows form running on a server.

Pretty interesting.
