    function scope

    I have a c# application with windows form for updating and retrieving some
    database table records. lets call it form1. I also have another application
    in vb that extracts data from the web but used the same database table as
    input to direct its operation. the data in the table is not useable directly
    but need a bit of transformation as done in the form1.


    how can I make retrieval functions in forml to the vb application? use the
    same package name but in different project?

    I want the vb app to control the form in terms of selecting the record but
    only if the form1 is instantiated by the vb application.

    if I just use the instantiation of application method, I don't know how to
    make available the required functions and the called internal function
    without the public

    thank you for your time and expertise.

      Explaining what you need to do all in one reply is a bit much but I
      will do my best to point you in the right direction. One approach to
      this is to make a 3rd assembly which has in Interface in it and you
      need to have your VB or C# app implement this interface that way one
      or the other app can instantiate/launch the other app and get the
      object tnat is implementing the interface and it can call methods/
      properties on that object.

      Good luck!

          I will search on the subject for interface to implement instantiation by the
          vb app of the c# app.

          just curious, is it possible in vb to create a class inherited from the cs
          class application?
          if so, can I not use some sort scope equivalent to friend or protected?

              Re: function scope

              VB.Net and C# compile to the same managed intermediate language code, so you
              can certainly work with assemblies written in either language from either
              language. This means that, yes, you can inherit a class in a C# project by a
              class in a VB.Net project.
