I am developing a small little Service Control Application. I am
using a listview control with checkboxes and getting the list of
services I want to control from a text file. When you check a
checkbox, it should either stop the service or start the service
depending on each respective service's status. I want the listView
to update the status for each service as they are checked. instead
all I can seem to do is clear the listView and I try running the
ListServices Function I created again, but the application just
hangs. The code is below:
