Here an article I was reading about some of the new (and from the looks of it... very useful) features of WCF.

One-Way calls, callbacks, and events.

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".

This service is down right now, but it looks like it might be very useful!

I have been fighting with this lately, but here is something I haven't tried... rewriting the interface that is giving me problems.

Not sure if this will work, but I will give it a try.

More in the souce...

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.

Here are some nice step by step directions for getting HTTP Compression setup in IIS6.

They also link to a nice site that will do a compression test for you on the public side.

I was trying to test stuff that wasn't public, so I figured out how to test this with Fiddler.

Once you start a trace with fiddler, if you select a session, they will check a box next to the type of compression None/GZIP/Deflate, which was used.

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"

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 is a 3 part article on the use of design patterns in ASP.NET.

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.

I have written a few programs in .Net that utilize Active Directory (AD), and what a pain it was.

Here is an article where the author created classes to encapsulate some of the objects in AD, which is pretty similar to what I did.

Keywords: LDAP, AD, Active Directory

If you are Microsoft, why do you create a function "TypeOf" that has totally differnet applications in VB and C#?

Typeof in C# is like GetType in VB, where VB uses TypeOf to see if 2 types are the same or check for interface implementation.

Kinda dumb.

I came across this offer where you get $50 free (I haven't read the details) for using Microsofts adCenter (just like adwords I guess).
