I want to create a basic dll file that i can use to check serial codes.

I have an instalation programme and wanted to use such a dll in my programme if pos. any ideas greatful recieved:)

What programming language do you plan on using?

Any language really dont matter. Im just knew to it.

Unless theres any pref free progs out there that do it for u.

I use .NET so all you have to do is create a new WindowsApplication and under the project properties put the Output setting to a ClassLibrary.

This will compile your project as a DLL file. Which you then can import into another project for use.
