Simple Ping in VB 2..3 - Imports System.Net.NetworkInformation?????

Hello All,

I'm a "somewhat decent" VB6 programmer making his first steps into VB 2003.  I'm just trying to duplicate some of my VB6 projects.  

One of them is a simple ping program.  On this site, I've seen a few references to doing this.  All of them mention that I need to "Import" System.Net.NetworkInformation.  However, when I look in PROJECT-Add Reference, I don't see that .Net or .Com object.  

The code example on this site is great...I just need to know how/where I can get this reference into my project.  

Chris, Baltimore.

Using "Import" doesn't necessarily require the Project > Add Reference procedure.

Just add to the top of your code:

Import System.Net.NetworkInformation

All it does is say "If I refer to something like System.Net.NetwokInformation.SomeClass I don't want to have to write the System.Net.NetworkInformation part every single time, so if you can't figure out what I'm talking about try it with a System.Net.NetworkInformation prefix on it."

If you don't mind the typing, even that's unnecessary.

Thanks for the quick info....a snipit of the code I'm trying:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Imports (system)


        Dim testPing As New Ping
        Dim testResult As PingReply
        Dim testAddress As String = "www.yahoo.com"

        testResult = testPing.Send(testAddress)
    End Sub
End Class

The problem is that I get the squiggly lines under "ping" and "pingreply" like it doesn't know what they are.   Even when I type in the system.net.networkinformation, it doesn't bring up networkinformation as a possible setting, just networkaccess and a list of others.

I think I'm just missing the reference/component, but I cannot find it....

There's no need to add any special references, however you do need to be using version 2.0 of the .NET framework.  If you're in VS 2003 I expect you're using 1.1 (where there is no mechanism to ping anything).  Version 2.0 came out with Visual Studio 2005.  Come to think of it, I don't think 2.0 is compatible with VS 2003.

Looking at that snippet of code, incidentally, the Import belongs waaaaay at the top of the file, before any other lines of code.  It's not something done on a per-method basis.  There are also no parentheses; it's just:

Imports System.Net.NetworkInformation

That makes sense...I am using 1.1......I'll see if 2.0 is compatible with 2003.  


Going to Project > Add Reference procedure. Is that the same as right clicking on the project in the explorer window and clicking on add reference ?

Just im thinking in terms of Project --> Add reference in terms of using the menu at the top as apposed to right clicking on the project in the explorer window on the right ( its generally on the right hand side )
Yes, any way you add a reference to the project it has the same result.  In general anything you do from the Project menu is the same as what you'd do by right-clicking on the project.

I admit Microsoft has some strange UI ideas sometimes, but having identical features in two different menus behave differently is a bit out there even for them.  (-:
if you need Ping for DotNet 1.1, maybe this will help
