Use .NET DLL in Delphi 5 Professional

How can I use a .NET DLL I wrote in Delphi 5 Professional?  I tried importing it using the Import Type Library but it said "Error loading type library/DLL.".

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I think that is something they have addressed / are addressing in version 7 of Delphi.. but I dunno about using it in 5.. =(

  the .Net DLL isn't com libarary, so you can't import them using import type Library, to be able to use the .Net technology, you need Delphi.Net preview Compiler that bundled with Delphi 7 package.

There's open source project to enable Delphi 5 and above to communicate with the Microsoft .NET-Framework.

It is possible to create COM registered assemblies, though you do have to make a signed assembly to COM to use it, and this means there can only be one instance of the assembly can be available on the machine.

Have a look on MSDN for instructions on creating a COM compatible .NET assembly.

Hope this helps.
