    VB IDE Closes when Application Ends

    I have just started using VB 6 (I'm an old VB 4 and C++ developer), and I'm debugging an application. Funny, though, whenever I "End" the app, either by pressing the Debug | End button (or from menu), or even if I choose System Menu | Close in the app, the applicaiton ends, but so does the VB IDE.

    Anyone have any ideas?

    Thanks in advance.

    Do you have all the serivce paks installed (5 is the latest I think)? Also, are you using any API calls that may not be cleaning up after themselves?

    Yes, I am using SP 5, and I'm not outwardly using API calls. I am, however using this platform to debug a COM object dll.

    Ok, something in that interface must be the problem. I just commented out the COM calls and the IDE doesn't quit.

    Sometimes it just takes a little rattling from the outside world.

    Ide crashes

    ...it does not close: it crashes.
    If you have com components, you should stop them correctly.
    Pressing end button does not fire the unload events of your form and the terminate event of your components.
    Instead, you should provide a button and or menu item choosing which you should:
    Unload all forms
    'in your main form:
    Private sub Form_QueryUnload(Unload mode as integer,Cancel as integer)
    dim frmX as form
    for each frmX in forms
      if frmX.name<> me.Name then
          unload frmX
      end if
    'here properly close and set to nothing your components
    'This is pseudocode, as I do not know
    'which componentrs are you using
    set myComp01= nothing
    set myComp02= nothing
    End sub
    ...at present time, using mainly Net 4.0, Vs 2010

    Special thanks to Lothar "the Great" Haensler, Chris Eastwood , dr_Michael, ClearCode, Iouri and
    all the other wonderful people who made and make Codeguru a great place.
    Come back soon, you Gurus.
