    I am very new to VB . NET but have still managed to code small projects with regular POST and GET webrequests. I know a decent amount already.

    I am trying to make a tool for a site that uses the multipart POST request and am failing to figure it out.

    Here is some of the data extracted from the headers of the requests...

    Code:
    Content-Type: multipart/form-data; boundary=---------------------------134911937220404Content-Length: 817
    -----------------------------134911937220404
    Content-Disposition: form-data; name="site_key"
    
    
    kNtXqixV
    -----------------------------134911937220404
    Content-Disposition: form-data; name="submit_hidden"
    
    
    submit_hidden
    -----------------------------134911937220404
    Content-Disposition: form-data; name="site_code"
    
    
    this is the paster
    -----------------------------134911937220404
    Content-Disposition: form-data; name="site_format"

    I can get the "site_key" value using GET and regex but dont know how to compile a multipart POST request.

    I am sure a lot of you guys know how to do this so a little explanation and sample code would be very helpful for me.

    Thanks in advanced.

    multipart is necessary only for transporting binary data (i.e. uploading files). When you aren't doing that, you don't have to use it.

    Yes that's true.

    I am working on coding a program for two sites right now.

    1 is a site that has your average picture file that uses miltipart
    2 is pastebin.com (i am trying make a pastebin poster as a learning exercise i guess) but yeah that is multipart POST from the example i posted above.

    Do you have some example code or a really good tut online?

    I have spent the last two days trying to follow various guides online but i am not having much luck following/understanding

    Yeah I have read over that earlier but can't seem to wrap my head around everything.

    I will keep reading and trying, im sure I will get it eventually.
