    Calling VB.Net Class File from Delphi

    Hi there,

    I have to integrate a .Net application into a Delphi application somehow.
    The simplest method is to get the Delphi app to call a .Net console app,
    however it would be better for various reasons if I could make the .Net side
    a DLL and this is what I am wondering about.

    Is there any way to call a VB.Net Class project from a Delphi application? I
    seem to recall there is a way to call a .Net DLL from VB6 but vague on
    details (or imagining things) and not sure if this would also make it usable
    from Delphi.

    Any help appreciated...

    Cheers

      Can you use COM?

          Hi Three,

          The .NET class is only callable from .NET code, unless the class exposes COM
          interfaces, then you can access it from COM applications. If you can't modify
          the existing classes and they do not expose COM interfaces, you could always
          write a .NET wrapper that does expose the COM interfaces and passes calls
          through to the .NET classes. Alternatively, if you are using Delphi, you could
          try using Delphi for .NET.

                  AFAIK, if your not talking about Delphi.Net which is the new version, you
                  will have to expose your .Net classes as COM objects and import them into
                  Delphi that way. The new version of Delphi is fully .Net compatible so you
                  should be able to use any .net assembly with it.
