Display WiFi Networks in VB.net - Tɦɛ Alex - Dec 22, 2015

Hey guys

I'm wanting to display wireless networks in a VB.net list box but only their SSID names.

I've found that 'netsh wlan show networks' is promising an I am executing it like this:

Code 
Public Sub ScanNetworks()

        Dim output As String

        Dim proc As New Process()

        proc.StartInfo.CreateNoWindow = True

        proc.StartInfo.FileName = "netsh"

        proc.StartInfo.Arguments = "wlan show networks mode=bssid"

        proc.StartInfo.RedirectStandardOutput = True

        proc.StartInfo.UseShellExecute = False

        ' required for the Redirect setting above Process.Start(proc);

        proc.Start()

        output = proc.StandardOutput.ReadToEnd()

        MsgBox(output)

    End Sub

Problem is netsh will also bring a lot of useless information that I not required for the program I am making. At this point, I'm kind of stumped.

Anyone have any ideas how I can retrieve only the SSID and nothing else?

I've found some resources online about using Substrings to read to the end of a string. Below I'll provide as much information as I can.

This is the output from netsh wlan show networks

Code 
netsh wlan>show networks

Interface name : Wireless Network Connection

There are 2 networks currently visible.

SSID 1 : Jackks Room

    Network type            : Infrastructure

    Authentication          : WPA2-Personal

    Encryption              : TKIP

All I want is:

Code 
SSID 1 : Jackks Room

Obviously I need it too loop through so it will get SSID 1, 2, 3 etc...

Any ideas?

Thanks!

Well you just loop with String.IndexOf("SSID",lastLocation) and read until the new line, until you run out of SSIDs...

Disregard this thread. I found a Native WiFi API that did exactly what I needed.
