    Windows Service

    Hi everyone! I can create Windows Service in VB .Net 2003 professional.
    The problem is that when I try to show up a form in Service Start up
    event, the form always show up and become stop responsible! Any idea?

    Regards,
    Stanley

      Do not show forms from a service. Services should never interact with the
      desktop.

              It's possible, but it's bad design. Services can interact with the
              desktop, but to do so, they have to run with the LocalSystem-Account.
              This one can do everything with your system. The service window will
              be shown at the users desktop and so, it can receive window messages
              as any other desktop window. This can be used to attack the users PC.
              Also, if your service runs under WinXP with fast user switching, the
              service window will only be shown to the first logged on user.

              The better approach is a separate client application, which runs with
              user privileges and connects to your service through TCP-Sockets for
              example.
