Using Embedded resources in an ASPX-page/WebPart

I’m implementing UpdatePanel and UpdateProgress into my (Base)WebPart and since it is nice to have a ‘while processing’-image, I thought about embedding it as a resource.

This link helped me to accomplish this.

This post helped me to embed the required CSS and JavaScript directly into the page. 4GuysFromRolla have a very nice article here where I got the ‘modal updateprogress’ from I now use.

And again, when I get somewhere near to a complete thing, I’ll post a sample-solution with all this stuff in it.
