    calling .dll from HTML

    A person in a different division where I work asked for some help. He has an
    HTML website and wants to use some functionality in a .Net .dll that I've
    developed. I currently use this functionality on my ASP.Net website. I
    could easily port his HTML website into ASP.Net in about 5 minutes. The
    problem is that if anything on his site ever breaks in the future, I would
    own the problem because he isn't a programmer. I figured that if I just hand
    him a .Net .dll and some code to call it, he could manage and support it with
    no problems.

    Can a .Net .dll be called from a few lines in an HTML page and if so, how?

      Not clear...

      You can expose a .NET dll as a COM object. It could be then called server
      side...

      If for now the site contains just static HTML files it won't work (HTML is
      not a programming language, IIS will serve just these files). It should be
      then turn in to something server side scriptable such as ASP and then he'll
      be ablt to call this as a COM ovbject...

          Re: calling .dll from HTML

          Patrice,

          Thanks for responding. I understand you can take an HTML page and change
          the extention to .aspx and host this page on a webserver running the .Net
          framework. This is sometimes called in-line or code-beside programming and
          may appear as follows:

          <%@ Page Language="VB" %>
          <script runat="server">
          Sub Page_Load(sende r As Object, e As EventArgs)
          Response.Write( "Hello")
          End Sub
          </script>
          <HTML>
          ...Original HTML Page.....
          </HTML>

          I'd like to call a function in a .Net .dll that I have already written.
          I've tried putting this in the page:

          <%@ Import Namespace="Test DDL" %>

          and adding this to my Code block:

          Sub Page_Load(sende r As Object, e As EventArgs)
          Response.Write( "Hello")
          Dim myTestDDL as TestDDL
          End Sub

          but this does not work. Any ideas?

              Ok, just wanted to sort of the possible HTML static file issue...

              Using .NET it should be even issue. Did you put your DLL in the application
              /bin directory. If yes or if it still fails once done what is the message
              you have at compile time ?

                  Re: calling .dll from HTML

                  Yes. I put my .dll in the /bin folder. The error I get is:

                  Compiler Error Message: BC30002: Type 'TestDLL' is not defined.
