关于微机的实验报告,关于8251,8253,8255,8259的的设计

通过TreeControl控件显示数据库中的记录，优化界面。-TreeControl control through the display in the database records, and optimize the interface.

这么把数据库中的数据加到树控件中：这是一篇用WORD介绍的，里面有代码-database so the data added to the tree control : This is a use Word described, there are code

treeview控制展示，實做item的樹狀結構。(TreeView control to display, it is the tree structure to do item.)

类似良友的一个知识收集程序（原创）-good friend of a similar knowledge of collection procedures (original)

hhh理现对交通信号灯进行管理，车辆放行3分钟后，车行道黄灯闪烁5秒钟，以警示车辆将切换红绿灯。此时人行横道仍维持红灯点亮。车行道的黄灯闪烁5秒钟后，转为人行横道行人放行1分钟，然后再转为车行道车辆放行3分钟。如此循环重复。 用发光二极管模拟信号灯，8255A实现对信号灯的控制（所用端口自定），8253的计数器2定时向实验系统主片8259A的IRQ7请求中断，以实现3分钟，5秒钟和1分钟的定时。 实验系统8253计数器2的CLK2可接OPCLK，频率为1.19318MHZ，GATE2已接＋5V，定时可采用软硬件结合相结合的方式-HHH Jimmy is right for traffic signal management, vehicle clearance three minutes later, the driveway five seconds flashing yellow light to warn vehicles will switch traffic lights. This sees the red light remains lit. The flashing yellow light carriageway five seconds later, the pedestrian crossings to release a minute and then released into driveway vehicles for three minutes. So the cycle to repeat. Using light-emitting diode signal simulation, 8255A right signals control (used to set the port), the 8253 regular counter to the two experimental system of the main unit there 8259A interrupt request, to achieve 3 minutes, 5 seconds and one minute timing. Experimental System to the 8253 counter two OPCLK CLK2 access, frequen

文件浏览treeview控件,实现windows资源管理器的功能-file browser treeview controls, windows resources management to achieve the functions

相信很多人都在早树与列表结合的界面，现在提供一个给大家，listview与treeview的完美结合。-Many people believe that the tree in the morning combined with a list of interfaces, is now available to everyone one, listview with the perfect combination of TreeView.

TreeView控件来显示，它是用树结构来做项目的。

能够很容易控制的一个Tree类。通过该类可以创建自己需要的风格化的树，有利于在特定环境下使用。(can be easily controlled by a Tree class. Through such needs can create your own style of the tree, to the specific environment.)
