I have problem with one button with LFSlib, the conflict is with namespace.

Erm..... LFSLib is C#. i think you need to look up on C# before attemting to do this.

ups, sorry, C#

So your problem is, that there is already another class names "LFSButton". Rename your class or change your namespace.

anyway, you shouldn't use that namespace for your projects and include the lfslib as .dll file and not the whole source code
