Best Way To Get MAC, IP And ComputerName

[Slyke]

Hmmm... What would be the best and easiest way to find out the MAC Address, IP address and Computer Name, by knowing any one of these?

For example, If you knew the MAC Address you could find out the IP address and the computer name. Or if you knew the IP Address you could find out the MAC Address and the Computer Name. Remote computers of course on a LAN (Administrator access).

Is this possible to do in VB? Without shelling out to command prompt or the such? Winsock controls are fine.

For IP Address, use the Winsock control and do

MsgBox Winsock1.LocalIP

For Computer Name use

Private Declare Function GetComputerName Lib "kernel32" Alias "GetComputerNameA" _
(ByVal lpBuffer As String, nSize As Long) As Long

Private Sub Command1_Click()
Dim strBuffer As String
  Dim lngBufSize As Long
  Dim lngStatus As Long
  
  lngBufSize = 255
  strBuffer = String$(lngBufSize, " ")
  lngStatus = GetComputerName(strBuffer, lngBufSize)
  If lngStatus <> 0 Then
     MsgBox ("Computer name is: " & Left(strBuffer, lngBufSize))
  End If
End Sub

I had to do a search for this MAC address.

Have a look at this thread.

  lngStatus = GetComputerName(strBuffer, lngBufSize)
  If lngStatus <> 0 Then
     MsgBox ("Computer name is: " & Left(strBuffer, lngBufSize))
  End If
End Sub

These are all for the local machine. I'm talking about Remote machines that i have administrator access to over a LAN (Not a domain, a workgroup, but that doesn't really matter).

I'm trying to create a WoL (Wake on LAN) program. The program will use Net View to get a list of the computers and from there get the MAC addresses and IP addresses. But the user can also enter in a MAC address/IP Address/Computer Name and the program will automatically figure out the missing data.

My problem is that i don't understand how to get the data from NetBios and TCP/IP and all that to get the returned MAC address when something is sent to an IP address, or how to convert Computer Names into IP Addresses.

Perhaps these would give you some hints.
