FTP question

[KillerOfDN]

Hi, I am stuck on some code I have to upload a file to my FTP server. I keep getting an error: The remote name could not be resolved: 'ftp.mywebsite.com'

' set up request...
        Dim clsRequest As System.Net.FtpWebRequest = _
            DirectCast(System.Net.WebRequest.Create("ftp://ftp.mywebsite.com/test.txt"), System.Net.FtpWebRequest)
        clsRequest.Credentials = New System.Net.NetworkCredential("username", "password")
        clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile

        OpenFileDialog1.ShowDialog()
        ' read in file...
        Dim bFile() As Byte = System.IO.File.ReadAllBytes(OpenFileDialog1.FileName)

        ' upload file...
        Dim clsStream As System.IO.Stream = _
            clsRequest.GetRequestStream()
        clsStream.Write(bFile, 0, bFile.Length)
        clsStream.Close()
        clsStream.Dispose()

I use File Zilla for uploading my files via FTP, in the Host Name box on File Zilla, I put my domain name.com, enter my username and password and login sucessfully...

However, when I try this on VB.NET (using the code above) I keep getting this error... Any help as to why this might be happening?

Many Thanks
