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)

(1).本程序是用powerbuilder语言编写的，运行环境是powerbuilder9.0。 (2).本程序能实现基本的四则运算，平方运算，阶乘运算，开方运算，自然对数运算， 求正弦、余弦，N与∏的乘积运，本程序能显示17位整数，超过17位则自动转换成 科学计数法形式，并保留15位小数。 (3).出现计算器页面后点击on/off后方可运行。 (4).本程序提供键盘和按钮输入两种方法。((1) This procedure is used powerbuilder language, the operating environment is powerbuilder9.0. (2) This procedure can achieve the four basic arithmetic, squaring, factorial computation, root operation, the natural logarithm operation, sine, cosine, N and Π product shipped, the program can display 17 integer, more than 17 bit is automatically converted to scientific notation form, and retain 15 decimal places. (3) The emergence of the calculator page and click on/before after running off. (4) This program provides two ways to enter the keyboard and buttons.)
