I've never used VB, so I don't know what msflexgrid is. I think most/all
of the c# packages have analogues in vb.

Here's a blurb from MSDN
This example determines whether the specified Web site responds.

Example
Try
    Dim siteUri As New System.Uri("http://www.microsoft.com")
    Dim webRequest As System.Net.WebRequest = _
        System.Net.WebRequest.Create(siteUri)
    webRequest.Proxy = New System.Net.WebProxy("YourProxySetting")
    Dim webResponse As System.Net.WebResponse = webRequest.GetResponse()
Catch ex As Exception
    ' The Web request failed.
End Try
Compiling the Code
This example requires:

A reference to the System.Web namespace.
If the Web site does not exist, an exception is thrown by the
GetResponse method.

The value of webRequest.Proxy will depend on your network. For more
information, see WebRequest.Proxy Property and WebProxy Class.

Robust Programming
The following conditions may cause an exception:

The Uri does not exist (WebException Class).
The proxy is incorrectly set (UriFormatException Class).
The Uri is not in the proper format (invalid characters, and so forth)
(WebException Class).

i think thats what i did but not entirelly sure
its possible that i messed up in the thread department but i'll take a
second look at it tonight cuz its laundry day and i gotta get going
btw one more thing: last time i installed vs.net i had msflexgrid but
now

it,
just incase you had this problem please respond otherwise ignore cuz i
