Listing Network Computers

I'm looking for a code that lists all computers in the LAN.
Is it possible? Is it difficult?

I'm doing the first steps in VB.

Help me. Thanks on advance

heres a class that does it, it can get other lists too such as shared list, printer list etc, i;ve attached the class, just add it to the project, and in your form load have something like thie....

Have a listbox on the form named lstTerminals

VB Code:

Dim SW As CNetworkEnum 'Decalre class
    Set SW = New CNetworkEnum 'Set class to SW
    Call SW.SetResourceType(0) 'Set resource type
    Call SW.Reset 
    Dim ST As String
    
    ST = Replace(SW.GetServerList, "\\", "") 'Replace the \\ in the computer names
 
    'loop through the list of computer names and put the in the listbox
    For i = 1 To Len(ST)
        If Mid(ST, i, 1) = "," Then
        lstTerminals.AddItem (Left(ST, i - 1))
        ST = Right(ST, Len(ST) - i)
        i = 1
        End If
    Next i

BTW i found this on pscode.com, theres probably more simpler versions, this was just the first I found

Thanks @the182guy for you reply.

I don't know how can I use it! I'm using VB .Net 2003.
How can I use the code and aply it to a listbox.

Sorry about the English but I'm a portuguese teenager.
And sorry for the ignorance!

Ah sorry, I thought you were using VB6, that code is for VB6, possibly you can use the class in .NET but I really have no idea, try posting in the .NET or API forum as this question is API related and technically is not actually network programming

Owever, thanks for all!
