最近开发的，用于课堂上给学员们演示的小程序；很小，但里面用到的编码应该是实际编程时常用的一些函数和方法。里面主要有四个窗体：w_study窗体内容是最基本的PB开发，里面的代码也是PB实际应用中相对常需要用到的技术。该窗体支持模糊查询，包含数据窗口的基本用法（检索数据、插入、删除、保存等）。其中“保存”按钮里面有用到从数据窗口获取数据的相关函数和对相关缓冲区记录状态的判断方法；w_mdi是一个MDIHelp类型的窗体，放置了个菜单，并插入了个图形用户对象u_pic_1作为背景；w_uo主要是个使用可视用户对象的窗体，里面乃至一个标准可视用户对象单选钮u_bt_1和一个定制可视用户对象文本框u_eg；inh_w_1是一个继承窗体，继承了w_uo窗体，且对其用法做了个简要说明。此程序仅适用于PB的初学者观摩之用。-recently developed for classroom presentation to the participants of small programs; Small, but they should be used in coding the actual programming is often used in functions and methods. There are four main forms : Form w_study content is the most basic PB development, inside the PB code is relatively practical applications often need to use the technology. The forms support fuzzy inquiry, the window contains basic data usage (data retrieval, insertion, deletion, preservation, etc.). With the "Save" button inside of the useful data from the window of access to data and the correlation function of state records related to the buffer- broken; w_mdi is a MDIHelp types of windows, placed menu, 000 and insert a graphical user object u_pic_1 as background; w_uo main use is targeting
