用VB做的一个摄影测量的单向空间交会程序 相比VC虽然没有这么简洁，但是很有启发性(Using VB to do a photogrammetric procedure compared with one-way space rendezvous VC Although there is no such simple, but very instructive)

说明：  本程序是将串口实时接收到的数据，然后将数据进行曲线绘制。(The data received by serial port is plotted in real time.)

说明：  Mapbasic编制的用于制图的多个工具程序。该程序已集于一个菜单下。(str preparation for a number of mapping tools procedures. The procedure has been set in a menu.)

access使用一段时间后文件会逐渐的变大,压缩后减少文件碎片,提供查询速度(access used for a period of time after the paper will gradually become bigger, compressed to reduce paper debris, inquiry speed)

VB平铺一个背景图到整个窗体，用一个图片，铺满整个窗体的背景，简单易用(VB tiles a background map to the whole form, and uses a picture to cover the background of the whole form. It is easy to use.)

采用VB6.0编程的MD5加密算法。MD5就是采用单向加密的加密算法，对于MD5而言，有两个特性是很重要的，第一是任意两段明文数据，加密以后的密文不能是相同的；第二是任意一段明文数据，经过加密以后，其结果必须永远是不变的。前者的意思是不可能有任意两段明文加密以后得到相同的密文，后者的意思是如果我们加密特定的数据，得到的密文一定是相同的。(Using VB6.0 programming of MD5 encryption algorithm. MD5 is the use of one-way encryption algorithm, for MD5, there are two characteristics is very important, the first is any two plaintext data encrypted ciphertext, later not to be the same second is an arbitrary piece of plaintext encrypted data, then, the results must always be the same. The meaning of the former is unlikely to have any two plaintext after getting the same ciphertext, which means if we encrypt specific data, the encryption must be the same. )

安装.net2003的系统组件时需要的文件之一，黏贴到C:/Program Files/Common Files/Microsoft Shared/Web Server Extensions/40/bin 中(Installation. Net2003 system components when one of the documents required, stick to C :/ Program Files/Common Files/Microsoft Shared/Web Server Extensions/40/bin in)
