Close process

[RobDog888]

You could loop through them all looking for a match...

Dim oProcess As Process
For Each oProcess In System.Diagnostics.Process.GetProcesses()
    If oProcess.ProcessName.ToString = "YourDesiredExe" Then
        MessageBox.Show("YourDesiredExe is running!") 
    End If
Next

Or just populate an array of processes of just the ones of the desired name...

'Gets first item
Dim oProcess As Process() = Process.GetProcessesByName("msnmsgr")
MessageBox.Show(oProcess.GetUpperBound(0).ToString)
