View 2 RepliesHow can I set a host IP address and port.. and then detect if the port is open (accepting connections)or closed (denying connections)I came across this while searching, but it doesn't seem to function all that well..Using the port 80 and the host [URL] The result it gave me was closed... which is obviously wrong.So what can I do?Code: ( I have also imported "System.Net" and "System.Net.Sockets" )
Dim host As String = "www.google.com"
Dim port As Integer = 80
Dim addr As IPAddress = CType(Dns.GetHostAddresses(host)(0), IPAddress)

I also found the use the WINSOCK control but I'm on Windows 7 64bit and that control doesn't even show up in the components section.
As part of my application I am hoping to be able to get the user to enter their IP address and subnet mask which will then enumerate all of the hosts in between which can then be scanned for various open ports/applications installed.
For instance, With a network of 10.91.100.0/255.255.255.252 hosts are valid 10.91.100.1 - .2
How can this be done in vb.net? I would assume also some error checking would need to be put in place to confirm as to whether the subnet mask was valid as well?
