I'm looking for the best way to make se of the function is a dll user
control in an ASP.NET page. I've been unable to find anything specific to
demonstrate how this can be achieved.

Mike
 
Could you ask that in more understandable terms, please?

What is "a dll user control?" And what do you mean by "the best way to make
se of the function i[n] a dll user control"?

The best way to make use of a hammer is to hammer nails with it. The best
way to make use of any tool is to use it for what it is designed for.

Kevin,
I've got a .NET dll which I would normally use within a VB.NET application.
It provides me with a set of classes and functions I can use to connect to a
back-end server. I'd like to be able to make use of those same classes and
functions in an ASP.NET page.

In an ASP page I would use the CreateObject() function to make use of the
classes in the equivalent COM object.

Okay, Mike. What you have is not a "Control" - a Control in ASP.Net is a
class which renders UI. It sounds like what you've got is a Class Library.
If so, all you need to do is create a reference to the DLL, and use it like
any other .Net DLL (Such as the built-in System.DLL, System.Web.DLL, etc).

Add the DLL as a reference in your project references. Use an Imports
statement in your CodeBehind class:

Hi Mike,

As Kevin has mentioned, the component dll is quite different from the
asp.net control (which is for web page UI design). And since you said that
the component is used be used in asp app as COM object, i think we need to
use .net's COM interop service to call the component rather than call it
directly.

#Microsoft .NET/COM Migration and Interoperability
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html/
cominterop.asp

#Introduction to COM Interop
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcn7/html/
vaconintroductiontocominteroperability.asp

and when we use the "Add Reference" in VS.NET to refernce a COM dll in .net
application, the VS.NET IDE will automatically create the .net wrapper
classes(which can be directly used in managed code) for the COM components.

Thanks.

Steven,
I have a .NET version of the dll, so I don't need to worry about COM
Interop.

I've now found a couple of examples which give me a basic framework to build
on.

Thanks,
Mike
