for for doing what sort of thing? i mean mIRC DLL's u would need some sort of programming exp in a language like C++ or C (this is the reason for my post i would like to see C# dlls working with mIRC) but for starting out @ programming i would recommend somthing like pascal or C or even C# if u have the framework SDK and the framework install (C# is the easiest of the languages i mentioned but there are some requirements)
