    Windows Service starts Process, but not the application

    Hey there...

    Plz...
    I'm writing a Windows Service that will check every x minutes if another
    program is running. If it cannot find the application running, it launches
    it...

    I had already enough trouble with make the timer tick... lol...




    Here's the code that i'm using:

    Dim sPath as String = "c:\project1.ex e"
    Dim iRunning as integer = 0
    Dim p as Process


    For Each p In Process.GetProc esses

    If p.ProcessName.T oString.ToUpper = sProcess.ToUppe r
    Then
    iRunning = -1
    Else
    If iRunning >= 0 Then
    iRunning += 1
    End If
    End If
    Next

    If iRunning >= 0 Then
    'Process.Start( sPath) 'Tried already both of
    these...
    Shell(sPath)
    End if




    Tks in advance,
    Christiano Donke...

      By default Windows services do not have access to the user's desktop. Thus
      the application is started on another desktop.

              You can right click on your service and in the properties, allow the
              service to interact with the desktop. This is NOT recommended,
              however, and will not work in Windows Vista.

              Why do you need a service to do this? Why not just create a standard
              console application and set it to run when the user logs on (i. e. in
              the Startup folder). Then the app can check for the process you want
              to start.

                  Or even you could perhaps launch the application using the scheduler and
                  have the application itself to stop launching if it detects a previous
                  instance is already running...

                  Most of the time knowing the ultimate goal can help to raise better
                  suggestions (depending on what this application is supposed to do, a service
                  could be better, does a user needs to do something with it ?)

                      Chris,

                      this service will check if another program is running.. The app that is
                      being check connects tha local database with the remote db, "trading"
                      infomration...
                      This app must always be running... but sometimes it crashes or some dumb
                      user closes it...

                      that's why i need this service... Otherwise, it's gonna be closed too..
                      lol...


                      I'll figure out how to install the service as local system service (and
                      not as local user), with parameters and then i'll post the results...

                      Christiano.

                          I'm writing this as an service, because the user CAN'T do anything to it...

                          it must check it a specific app is running (every 10 minutes). If not,
                          launches it, else sleep.
