Web request through proxy server

[Mike]

Does anyone see any problems with this VB .NET code? A customer is using it
and is getting an exception at the line:
myResponse = myRequest.GetResponse()

Private Sub btnTest_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles btnTest.Click

Dim myRequest As System.Net.WebRequest

Dim myResponse As System.Net.WebResponse

Dim myProxy As New System.Net.WebProxy

Cursor.Current = Cursors.WaitCursor

myRequest = System.Net.WebRequest.Create("http://www.ourserver.com")

myRequest.Timeout = 30000

' Obtain the Proxy Prperty of the Default browser.

myProxy = CType(myRequest.Proxy, System.Net.WebProxy)

If Not myProxy.Address Is Nothing Then

MsgBox("The default Proxy address is: " & myProxy.Address.AbsoluteUri)

End If

Dim newUri As New Uri(txtServer.Text)

' Associate the new Uri object to the myProxy object.

myProxy.Address = newUri

' Create a NetworkCredential object and assign to the Credentials property
of the Proxy object.

myProxy.Credentials = New System.Net.NetworkCredential(txtUser.Text,
txtPassword.Text)

myRequest.Proxy = myProxy

Try

myResponse = myRequest.GetResponse()

MsgBox("Connection worked!")

Catch ex As System.Net.WebException

MsgBox("WebException occurred connecting to server: " & ex.Message)

MsgBox("Exception status = " & ex.Status.ToString)

If Not ex.InnerException Is Nothing Then

MsgBox("InnerException.Message = " & ex.InnerException.Message)

End If

If Not ex.Response Is Nothing Then

MsgBox("Status Code: " & CType(ex.Response,
System.Net.HttpWebResponse).StatusCode)

MsgBox("Status Description: " & ("Status Description: " & CType(ex.Response,
System.Net.HttpWebResponse).StatusDescription))

End If

Catch ex As System.Exception

MsgBox("Unable to connect to server: " & ex.Message)

Finally

Cursor.Current = Cursors.Default

End Try

End Sub

I found the problem. There is a bug in the CF:
http://groups.google.com/[email protected]&rnum=5

I read there is a way to specify the Proxy Server for the .NET Framework in
the machine.config file. Does anyone know if the Compact Framework supports
this and also is there a way to also specify a user and password for the
proxy server in machine.config?

Since that bug was posted in March 2003, I'm wondering if it was fixed in CF
1.0 SP2?

Putting the Credentials in the WebProxy object works with a proxy server I
downloaded called Proxy+, but it doesn't work with a Raptor Firewall.
Putting the credentials in the WebRequest works with Raptor Firewall, but
you need to put the credentials in the WebProxy object for the "Proxy+"
server. This is with CF 1.0 SP2.

I'm using Proxy+ 3.00 (Build #232)

Since that bug was posted in March 2003, I'm wondering if it was fixed in CF
1.0 SP2?
