How can I get the program to find every computer on the network?

View 1 RepliesI am trying to write a program to ping computers on my network to see if they are turned on. So far i have the following:
Code:
If My.Computer.Network.Ping("192.68.0.5") Then
MsgBox("Computer is on.")
Else
MsgBox("Ping request timed out.")
End If
If i use ip addresses, this works fine but i would rather use hostnames due to the ip addresses being dynamic (something which is outside my control). Using the hostname, it reurns "Computer is on" if the ping is successful, but if the hostname cannot be found, instead on returning "Ping request timed out", an error occurs as follows:
A first chance exception of type 'System.Net.NetworkInformation.PingException' occurred in System.dll
I have recently finished a console application and deployed it to several computers on our network for testing. As it is just an EXE a copied to the hard drives of selected computers for now. When the app is launched it writes info to an sql DB so I always know which computers it is on.
During the past few weeks I have modified this app at least 6 times (improvements, adjustments, etc)
It is a paint to keep going back to the computers to update it with the new version, and getting mixed up which version i am on - LOL I am looking for advice on how I would go about doing this automatically, for example, it would be cool if I just had to put an updated file in a repositry and clients would use this to update.
In Visual Studio, when I view the properties of my application>assembly information - I can set a file version. Is it possible to extract this info and store it in a variable? I would like to dump the in my DB. Also I could then possibly compare the file version of the launched app against an updated file in a network share folder.
