    Intercomunicating projects


    Hi,
    I have a huge project that I have to divide into three different projects
    with three different executables. They have to share the same MDI form (Menu
    as is now). How do I go about it?
    Thanks in advance.

    I'm betting the easiest way would be to make them into DLL's. Then have the
    MDIform call the AX objects.

    Benjamin -

    Are you dividing your code into projects in order to prevent the use of too
    much memory? If so, then I have been trying to do the same, with some success.
    The main problem is identifying areas which are shared, and pulling then
    out, since even if a small part of a DLL is used, then the whole lot is loaded
    into memory.
    Also, sadly, you cannot use forms appearing in DLLs with an MDI form in an
    EXE (a serious downside IMHO). However, one workaround was suggested by Daniel
    Appleman. Instead of MDI child forms, he creates OCXs containing UserControls
    which has the necessary GUI on it. Then, whenever you want a particular "form",
    you instantiate a generic MDI child form, and stick an instance of your ActiveX
    control on it.

    Otherwise, I could have mistaken your intention, and all you are saying is
    that you are creating three EXEs, which happen to have the same MDI form.
    In which case - it's simple. As long as you don't directly reference any
    specific modules or global variables, you can simply share the MDI form between
    all the projects. And if you <really> have to reference a particular global
    variable, you could always using conditional compilation, and set the appropriate
    variable in the Project Properties -> Make property tab.

    Thanks Mark,
    I am really trying to carry out both procedures you explained. I like the
    DLL suggestion and I am working on it right away. However, I do not get the
    second solution. How do I share n exes using the same MDI form?
    Thanks again
    Benjamin

    Or...

    You can use make the DLL's form into a child window with the Set parent.

    For a really rough experiment see:

    Re: Intercomunicating projects

    Benjamin -

    I'm glad that the first idea is useful to you.

    The second idea was assuming that you had 3 EXE projects. You are not
    interested in sharing code other than the MDI Form. To do this, create the
    form in one project. Close this project, and save all the files. Create or
    open another project, and add the MDI form which you saved in the first. In
    this way, you can also add the MDI Form to the third project.

    All this means that the MDI form is compiled into each three project, and
    when you update the MDI form in any of the projects, you will have to
    recompile each project.

    Does this help?

    You could take a look at the Add-In control at http://home.swipnet.se/vbasic
    .. It will make it wery easy to create a group of projects with a dynamic
    client and dll servers.

    Best wishes...
