VB断点拷贝大文件（WIN7系统需要更改某个API函数，具体我也忘了）

小弟以前租碟在电脑上看VCD，有时候拷贝经典的影片到硬盘上可惜碰到比较粗糙的碟子就很难拷贝过去，因此编了个断点拷贝文件的程序。本程序用于拷贝大文件，并可在旧文件上接着拷贝本程序能在无法读取数据的情况下复制空白数据并跳过坏数据区接着拷贝，专门对付烂盘.
本程序特别适合在恶劣的环境下拷贝大文件，比如拷盘，在网络中拷大文件等。
本程序是一个VB程序，包括5个文件，主窗口为 frmCopy 
使用了 Microsoft Common Dialog Control6.0 和
Micorsoft Windows Common Controls 6.0 两个控件库
拷贝文件使用了Win32API,速度比较快。
