it doesnt matter where you connecting or how you are connecting. as long as you are processing your requests on server side you can get the data and the content of any page passing correct parameters. for example we have written a code to content of the mails from live mail...

            HttpWebRequest mailLive = (HttpWebRequest)WebRequest.Create(new Uri(uriString));
 
            // create a Cookie Container
            CookieContainer cookieContainer = new CookieContainer();
            mailLive.CookieContainer = cookieContainer;
            mailLive.AllowAutoRedirect = true;
 
            mailLive.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip,deflate");
            mailLive.Accept = "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-ms-application, application/vnd.ms-xpsdocument, application/xaml+xml, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, */*";
            mailLive.Headers.Add(HttpRequestHeader.AcceptCharset, "iso-8859-1, utf-8, iso-10646-ucs-2;q=0.6");
            mailLive.Headers.Add(HttpRequestHeader.AcceptLanguage, "en-us");
            mailLive.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; WOW64; SLCC1; .NET CLR 2.0.50727; .NET CLR 1.1.4322; InfoPath.2; MS-RTC LM 8; .NET CLR 3.5.21022; .NET CLR 3.5.30729; .NET CLR 3.0.30618; SPC 3.1 P1 Tc";

            byte[] postBuffer = Encoding.GetEncoding("iso-8859-1").GetBytes(postData);
            mailLive.ContentLength = postBuffer.Length;
            mailLive.UnsafeAuthenticatedConnectionSharing = true;
            HttpWebRequest mailLive = (HttpWebRequest)WebRequest.Create(new Uri(uriString));

            // create a Cookie Container
            CookieContainer cookieContainer = new CookieContainer();
            mailLive.CookieContainer = cookieContainer;

            mailLive.Headers.Add(HttpRequestHeader.AcceptCharset, "iso-8859-1, utf-8, iso-10646-ucs-2;q=0.6");
            mailLive.Headers.Add(HttpRequestHeader.AcceptLanguage, "en-us");

            mailLive.ContentType = "application/x-www-form-urlencoded";


            mailLive.Method = "POST";
            byte[] postBuffer = Encoding.GetEncoding("iso-8859-1").GetBytes(postData);
            mailLive.ContentLength = postBuffer.Length;
            mailLive.UnsafeAuthenticatedConnectionSharing = true;

if you reach this point, you will need a stream reader to read and parse the rest of the content... hope this will give you some ideas. the code is written in C#.

this is just a part of the code. i cannot post complete source code here.

Enjoy

so you're saying the output from the PHP file is:

2
#1

In the HTTP Body?

So that means you have some junk before the #1.

If you just use the browser, and populate the URL with:

server.com/validtaion.php?user=testlogin&pass=testpass

If it returns 1 or 0 correctly. Then you can forget about the PHP side of things, and know that there is something wrong with the VB side.

The languages used really doesn't affect anything, since you're working with text here. (the text in the HTTP Body, it doesn't matter what created that text).
