The Start method of the Process object is possibly one of the most underappreciated tools available to a programmer.As a. For Each p As Process In processes ' Display process properties. Dim processes() As Process = Process.GetProcesses() Console.WriteLine('Count: ', processes.Length) ' Loop over processes. VB.NET program that uses Process.GetProcesses Module Module1 Sub Main() ' Get processes. You won't have permissions to kill most of the processes you're looking at in your list, so, catch the exceptions and ignore those processes you can't kill. Process.GetProcessById(port).Kill() The problem with this is that you don't have that call wrapped in a Try/Catch block. Process localById = Process.GetProcessById(1234) // Get processes running on a remote computer. This will throw an exception if there is no such process. Process localByName = Process.GetProcessesByName('notepad') // Get a process on the local computer, using the process id. The Process component is a useful tool for starting, stopping, controlling, and monitoring applications. The following VB.NET program allows to start multiple calculator applications and later it kill the same instances of all calculator applications. I know this is an old thread but this will kill all processes with the name notepad: Dim pList() As = ('notepad') For Each proc As In pList proc.Kill() Next This is the same as the answer that kleinma posted 5 years ago. The message loop executes every time a Windows message is sent to the process by the operating system.

When a process with a graphical interface is executing, its message loop is in a wait state. The Kill method forces a termination of the process, while CloseMainWindow only requests a termination.
