Looks like async development got a whole lot easier in .Net 4.5:
Visual Studio 2012 introduces a simplified approach, async programming, that leverages asynchronous support in the .NET Framework 4.5 and the Windows Runtime. The compiler does the difficult work that the developer used to do, and your application retains a logical structure that resembles synchronous code. As a result, you get all the advantages of asynchronous programming with a fraction of the effort.

We have a snowstorm!
After fixing some problems with my collision detection system, I got it working! It’s rough, but some added work on the physics side, and more tuning and it will be even sweeter!
Today I needed to be able to POST
to a form in order to submit for values as well as upload a file. All using HTTP POST.
The first step was finding out that there does not seem to be a native way to post both form parameter and upload a file together.
allows for the parameter name/value pairs, but sets it’s encoding type to
which is incorrect for file uploads. The code for this would look something like this:
I found that
*BUT* there is no way to post parameters, and the request is not properly formatted. To clarify, it will work fine with a IIS webserver, but any other real webserver (Apache, Tomcat) would choke on the malformed output. Microsoft does not do standards too well if you have not noticed. Microsoft — if you are reading this, kindly go read RFC1867. The call would look like this
does set content type to
My main issue is not the incompatibility in this instance, but rather that I cannot post parameters and the file in the same post.
In order to solve this, I found a excellent class written by Gregory Prentice. I compiled the c# class and included a reference to it in my vb.net app. Then it was a simple matter of adding the reference
and adding this code:
And booyah it works!

I finished a sweet .net app today. It’s vb.net which is kinda gay I guess but it gets the job done and is a lot better than the VB I knew long ago. The app itself spawns a new process and runs a netsh command extracting/grepping out the info needed.
I’m headed to PRI tomorrow. Tired and should of already been sleeping. damn black ops.
