    launch on startup

    I'm new to vb.net and was wondering what the syntax is for application
    events such as starting up or shutting down. For example, if you would just
    like to get a user's name with an input box when they open the app or a
    form.

    Thanks

      Re: launch on startup

      It depends on what you want the application to do and what type of
      application you are creating (Windows Forms, WPF, Web, etc) - not much help
      I know.

      Can you give us an idea of the scope of your application and we can offer
      more help either on the newsgroup or by emailing me directly.

      It is also worth picking up a VB.Net book or two to help you get started.

      Kind regards

      Rob

          Re: Re: launch on startup

          I just found "ApplicationEve nts.vb" which is hidden by default. I
          forget how to show it but it is probably easy to find -- I found it so
          how hard could it be!

          It has several events but no prototypes. That seems a tremendous
          oversight!

          I am using the one for StartupNextInst ance to notify the user that the
          program was started twice. The application takes care of exiting (if
          you set the single instance check in My Project>Applica tion) but not
          notifying the user. If the application is hidden in some way and the
          user clicks on the icon/shortcut once again, then just quitting is not
          helpful to the user. They will probably click it a few more times and
          then logoff or reboot thinking something is drastically wrong. So a
          message seems appropriate.

          It took a little time to get it right since there are no prototypes.

          Here are the events that this namespace handles:
          ------------------------------------------------
          ' The following events are available for MyApplication:
          '
          ' Startup: Raised when the application starts, before the startup form
          is created.

          ' Shutdown: Raised after all application forms are closed. This event
          is not raised if the application terminates abnormally.

          ' UnhandledExcept ion: Raised if the application encounters an
          unhandled exception.

          ' StartupNextInst ance: Raised when launching a single-instance
          application and the application is already active.

          ' NetworkAvailabi lityChanged: Raised when the network connection is
          connected or disconnected.
          ------------------------------------------------
          That might be too early for you if you want to get input from a text
          box, though. That's code after you are running, not during startup.

          Here is the code for notifying the user of a multiple invocation:

          Private Sub NotAgain(ByVal sender As Object, ByVal e As
          Microsoft.Visua lBasic.Applicat ionServices.Sta rtupNextInstanc eEventArgs)
          Handles Me.StartupNextI nstance
          MsgBox("Only one copy of PVM1010 Companion can run on a computer.
          Second invocation is exiting.")
          End Sub

          (note the lines are wrapped due to Usenet length restrictions, not VB
          line continuation)

          To make this work for startup, remove the characters "NextInstan ce"
          everywhere it appears. I don't know the prototypes for the other calls.
          Good luck on that. Intellisense might help you with it but you have to
          type it all manually as far as I can tell.

          Mike

              Which version of VS are you using. Both 2005 and 2008 have access to all
              application events thru the project properties. (not that intuitive but
              ....). Right click on your project , select properties. On the displayed
              dialog select "View Application Events". From the IDE you should be able to
              dropdown the events and get the IDE to generate the stubs.

              On the same dialog is the "Make single instance application" check box.
              This is only available if you have "Enable application framework" checked.

              Hope this helps
              LS

                  VS2008/VB9 is my current weapon against paying for all software.

                  And speaking of non-intuitive. You have to check something to get
                  "Configurat ion" to appear (it does not even show, never mind disabled)
                  in Project Properties>Comp ile. I found it after some searching. I had
                  seen it before but it went away and finding it was quite a pain since I
                  could not see it, I did not know what to search for to get it back.
                  Goodness, some of the options are in the strangest places! I don't
                  remember what and were you check to get Configuration and Platform to
                  appear. It is hidden somewhere. Why the would hide it instead of
                  disabling it is another little mystery of life.

                  And, yes, dropping down the event name does create the prototype. I had
                  never done that. It works!

                  Thanks,
                  Mike
