Hi all,
I have the following code which uses WebClient.UploadValues
myNameValueCollection.Add("Name", name)
myNameValueCollection.Add("Age", age)
..............
.............
Dim web As New System.Net.WebClient
web.Headers.Add("Content-Type", "application/x-www-form-urlencoded")
Dim Results As Byte() =
web.UploadValues("https://hsbc-secure.com/cgi","POST",
myNameValueCollection)
Response.Write("Response received : " +
Encoding.ASCII.GetString(Results))
When the code executes, I'm getting the following error. Is this
something to do with permission problem? I've tried using form post
method(see the code at the end) and it works fine. Any idea?
Exception Details: System.Net.WebException: The underlying connection
was closed: Unable to connect to the remote server.

Other method which works fine:
Dim script As New System.Text.StringBuilder
script.Append("<form name=Form1 action='https://hsbc-secure.com/cgi'
method=POST>")
script.Append("<input type=hidden name='Name' value='" & UserName &
"'>")
script.Append("<input type=hidden name='Age' value='" & UserAge &
"'>")
script.Append("</form>")
script.Append("<script
language=javascript>cpiForm.submit();</script>")
Response.Write(script.ToString())
Many thanks.
