So I made a script to upload a file :

<html> 
<body>
  <form enctype="multipart/form-data"  method="post">
    <input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
    Choose a file to upload: <input name="uploaded_file" type="file" />
    <input type="submit" value="Upload" />
  </form> 
<?php
include 'global.php';

//Check that we have a file
if((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0)) 
{

  //Check if the file size is less than 350Kb
  $filename = basename($_FILES['uploaded_file']['name']);

  $ext = substr($filename, strrpos($filename, '.') + 1);

  if (($_FILES["uploaded_file"]["size"] < 20971520)) 
  {
        //Determine the path to which we want to save this file
        $newfilename = rand(1, 224323443738507);
        $newname = dirname(__FILE__).'/upload/'.$newfilename;
        //Attempt to move the uploaded file to it's new place
        if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$newname))) 
        {
           $rand = rand(1, 1024) . "_" . rand(3, 2673) . "_" . rand(5, 7337);
           $name = $_FILES["uploaded_file"]["name"];
           mysql_query("INSERT INTO uploads(id, name, todownloadname, path) VALUES('" . $rand . "', '" . $newfilename . "', '" . $name . "', '" . $newname . "')")or die(mysql_error());
           echo "It's done! The file has been saved <a href=download.php?id=" . $rand . "> ->>here<<- " . "</a>";
        } 
        else 
        {
           echo "Error: A problem occurred during file upload!";
        }
      
  }  
  else  
  {
     echo "Error: Only files under 20mb are accepted for upload";
  }
} 
else  
{
 echo "Error: No file uploaded";
}
?>	
</body> 
</html>

and I coded a function to upload the file in vb.net but it's not working for some reason. code:

If Not TextBox1.Text = "" Then
            Dim filepath, feedbackUrl As String
            filepath = TextBox1.Text
            feedbackUrl = "http://www.googler.co.cc/"
            Dim MyFile As New FileInfo(filepath)
            If MyFile.Length < 20971520 Then
                Dim boundery As String = IO.Path.GetRandomFileName
                Dim header As New System.Text.StringBuilder()
                header.AppendLine("--" & boundery)
                header.Append("Content-Disposition: form-data; name=""userfile"";")
                header.AppendFormat("filename=""{0}""", IO.Path.GetFileName(filepath))
                header.AppendLine()
                header.AppendLine("Content-Type: application/octet-stream")
                header.AppendLine()

                'Convert in binary format (ASCII)
                Dim headerbytes() As Byte = System.Text.Encoding.UTF8.GetBytes(header.ToString)
                Dim endboundarybytes() As Byte = System.Text.Encoding.ASCII.GetBytes(vbNewLine & "--" & boundery & "--" & vbNewLine)

                'Create and initialize the request
                Dim request As HttpWebRequest = DirectCast(WebRequest.Create(feedbackUrl), HttpWebRequest)
                request.UserAgent = "Mozilla/5.0 () AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.77 Safari/535.7"
                request.Method = "POST"

                'Write POST data to request

                request.ContentType = "multipart/form-data; boundary=" & boundery
                request.ContentLength = headerbytes.Length + New FileInfo(filepath).Length + endboundarybytes.Length
                Dim filebytes() As Byte = My.Computer.FileSystem.ReadAllBytes(filepath)
                Dim requestStream As System.IO.Stream = request.GetRequestStream()
                requestStream.Write(headerbytes, 0, headerbytes.Length)
                requestStream.Write(filebytes, 0, filebytes.Length)
                requestStream.Write(endboundarybytes, 0, endboundarybytes.Length)
                requestStream.Close()

                'Execute request and read response.
                Dim response As HttpWebResponse = DirectCast(request.GetResponse(), HttpWebResponse)
                Dim streamgt As System.IO.Stream = response.GetResponseStream()
                Dim length As Int64 = 100000
                Dim txt(length) As Byte
                streamgt.Read(txt, 0, length)
                streamgt.Close()
                streamgt.Dispose()
                TextBox2.Text = System.Convert.ToString(txt)
            Else
                MsgBox("File is bigger than 20MB")
            End If
        Else
            MsgBox("Enter path to file")
        End If

Any help is appreciated!
