    Working with DLLs

    Hello,

    With the help from people here, I've managed to make VB export functions and
    make my DLL app work from within another application. Now I am required to
    implement a functionality that when a user minimizes the main application,
    the VB DLL application will get minimized also. So, if the VB DLL B works
    inside application A, when A gets minimized, B gets minimized too. So far,
    when I run application B inside A, I am only allowed to work within B until
    it is closed. Is there a VB form property that modifies a state of a form?
    If not, is there anything else I should do? Sorry, I am quite new to VB
    environment and its functionalities .

    Thank you,
    Victor.

          Hi,

          Thanks for the reply. I put this code inside Form_Load() method but what it
          does is to start DLL application in a minimized state. There is an
          equivalent in form1 -> properties -> windowState options. But, I think it
          does have to do something with Window state and "Me" data member so I
          appreciate the idea.

          Thank you,
          Victor.

              Hi,

              Sorry, I probably have the weirdest questions here. What basically happens
              is when I run my custom DLL app inside a main application, all the
              functionalities of main application are disabled while the DLL app is open.
              What I need to implement is the enabling of both DLL app and main
              (container?) app functionalities which includes minimizing the main app
              together with DLL app - such are my bosses' specifications.

              Victor.

                  Notice that the scenario of exporting functions from VB6 DLLs is in no way
                  supported, although it is possible. There are certain things you'll have to
                  keep in mind, like potential threading issues. I don't recommend exporting
                  functionality that deals with VB6 UIs at all, and I would not take a project
                  with such a requirement.
