点量BT的开发目的是让用户无需关心和了解BT的具体实现细节，只需要写几十行甚至几行代码，便可以实现一个功能完善而且强大的BT应用软件。目前点量BT已经在多家客户的网吧游戏更新系统 / 教育视频BT下载系统中应用. 点量BT源码使用高效的c++代码编写，提供标准的动态链接库（DLL），可供C/C++、Delphi、C#、Java、VB等语言和各常用开发环境调用，让您完全像调用系统API一样的调用 -BT point volume was developed to allow users without concern for and understanding of BT specific implementation details, just to write dozens of lines and even a few lines of code, they can realize a fully functional and powerful application software BT. BT has been present at the volume of customers in the Internet cafe to update the game system/education video download BT System. Point the volume of efficient use of BT source c++ Coding, provides a standard dynamic-link library (DLL), available C/C++, Delphi, C#, Java, VB and other language and the common development environment called, allows you to completely the same as calling the system call API
