[VB.net] Httpwebrequest need to emulate javascript - Solvemedia Captcha Problems - Account Registration

Please fix this vb.net console project.

When I try to register an account on a website through the console application, the solvemedia captcha is always wrong. Even when the captcha is entered correctly.
It seems like the ccheck value (hidden form input field) is calculate on javascript basis but httpwebrequest does load javascript
So you need to emulate the javascript to get a correct ccheck value.

Requirements for coder:
- Javascript
- Vb.net -> httpwebrequest (Post)


For a professional developer this task might not take longer than 15 minutes.

I have attached further Project details as textfile and the (error free) vb.net project itself. You can run it in debug mode to understand.
Please read the textfile and take a look at the Project before you place your bid.
So you have a chance to understand the problem, thanks.
