UML的重要资料，我看后获益匪浅，大家可以下载来看看，随便下载。-UML important information, I look after the benefit, everyone can download to look at, just download.

VC系统下,地球坐标转换的源代码,在WGS-84坐标和北京54坐标之间的一套转换参数,可以全国通用的，在每个地方会不一样，因为它们是两个不同的椭球基准。-VC system, the Earth coordinates conversion source code, the WGS-84 coordinates and coordinate between Beijing 54 set conversion parameters can be nationwide, in every place to be different, because they are two different ellipsoid benchmarks.

将VC7.0和VC.NET的工程转换到VC6.0的工程,内有详细的介绍做法(自己试验后写的)-VC7.0 and VC.NET will convert the project to VC6.0 project, which has a detailed introduction of the practice (their own written tests)
