Trouble closing Google Chrome browser from within

RyanH11 used Ask the Experts™
I have an automation program that I'm developing that is doing most of what I want it to do.  I can open various web browsers without a problem.

When it comes to closing them, Firefox, Opera and Safari all close fine using the code

Dim p As Process() = Process.GetProcessesByName(SelectedBrowserName)
            For i = 0 To p.Count - 1
                        Do Until p(i).HasExited = True

Open in new window

Google Chrome however doesn't respond at all.  The only way I can get it to close is to use the 'kill' command which causes some grief when I next load up Chrome.  

I'm not 100% certain, but I'm pretty sure it used to work fine and has only started doing this in recent updates.  Can anybody offer a suggestion that reliably works with the current version of Chrome?

That is a little required multiple passes on my system...

This worked for me:
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim SelectedBrowserName As String = "Chrome"

        Dim ps() As Process = Process.GetProcessesByName(SelectedBrowserName)
        While ps.Length > 0
            For i As Integer = ps.Length - 1 To 0 Step -1

            ps = Process.GetProcessesByName(SelectedBrowserName)
        End While
    End Sub

Each process is associated with a tab it's possible the processes don't have a MainWindowHandle so for each process instance it means the MainWindowHandle could be zero. You might be able to filter by checking if MainWindowHandle of the process is greater then zero then use .CloseMainWindow


It has worked properly in all testing to date.  Many thanks.
