Getting Started

  1. Create a new Windows Forms Application
  2. Add reference to both library: Thn.dll and Thn.Interface.Vcl
  3. Your project can now use the controls. To make it easy for accessing these controls, right click on Visual Studio's Toolbox, click Add Tab. Then right click on the new tab, click Choose Items..., browse to the Thn.Interface.Vcl.dll


This library was developed during 2004-2008 by THN Solutions LLC and designed by software architect Nguyễn, M. HảiIn 2014, THN decided to opensource version 2.0 of the library for educational purposes and for contributing back to the community.

Currently, we are secretly cooking a new programming paradigm that aim to help developers build cross-platform, cross-device applications in 1/10th the time. You might want to check out this productive programming framework.
