Creating a DLL. Solution?

Hi. I developped an application and installed it on different computers. Now I have a problem. I would have to change some part of my coding at about every 5 months. Of course, I would like to do only some kind of 'updates' to my application. The first idea I had is to use a DLL. I never used DLLs and I want to make sure I'm going the right way.

Let's say I have one function that may need updates regularly. I would put that function in my DLL. Afterwards, I could simply build a new DLL with the updated function and overwrite the old DLL on every machines.

Can someone tell me if the idea is any good?

If so, where can I find complete documentation on building a DLL, including my different fuctions?

Thanks a lot

What you want to build is a class library and then compile it into a DLL. As you make changes to the underlying classes you will be able to do want you want as long as you don't break compatibility :( In other words don't delete methods or properties or change calling parameters. You might want to read the version compatibility section of the help file. As to building dll, I suggest you find a good book on building classes, there is number of them out there.

Good Luck :D
