vbnomwdifytime
VB6.0禁止修改系统时间的源代码，Windows系统时间有时是自动更新的，如果不选择自动更新，可以手动去修改它，但目前有一些流行的恶意程序为了自己软件方便会强制修改系统时间，本程序可禁止用户或程序修改系统时间，虽然主窗口打开后什么也没，但此时你双击右下角的Windows系统时间，弹出面板内修改时间的话，你会发现修改过的时间会自动恢复，无法修改。本程序的用意并不是在于让用户就这么运行着要程序，而是让VB编程者可从代码中提取出有用的代码，作为一个模块来用，实现禁止修改Windows系统时间的功能。(VB6.0 prohibit changes to the system s source code, Windows system automatically updates the time and sometimes, if you do not choose to automatically update, you can manually to modify it, but there are some prevalent malicious software programs for their own convenience will force changes to the system, this program can prevent users from modifying the system or program time, although the main window opens after nothing but time to time you double-click on the Windows system the lower right corner to bring up the panel s modification time, you will find the modified time will be automatically restored, can not be modified. This program is not intended that allows users to program running on so, but let VB programmers can be extracted from the code of useful code as a module to use, modify the Windows system time to achieve a ban functio)

msflexgridDemo
这个代码是基于MSFlexGrid基础功能进行改良扩展的示例----商业日报和私人旅行里程示例，代码增强了隔行变色，以及整行选择、双击事件，并加入了合计计算功能。同时支持打印输出模拟功能。整个代码为一个类文件，大家可以再此基础上继续扩展和修改。(This code is based on the basis of the functions of MSFlexGrid improved sample expansion---- Business Daily and private travel mileage example, color code to strengthen the de-interlacing, as well as the choice of the entire line, double-click events, and joined the combined computing power. At the same time, support for analog functions printout. The entire code into a class file, we can continue to expand on this basis and modified.)

中频感应加热以其加热效率高、速度快，可控性好及易于实现机械化、自动化等优点，已在熔炼、铸造、弯管、热锻、焊接和表面热处理等行业得到广泛的应用。
本设计根据设计任务进行了方案设计，设计了相应的硬件电路，研制了20KW中频感应加热电源。
本设计中感应加热电源采用IGBT作为开关器件，可工作在10 Hz～10 kHz频段。它由整流器、滤波器、和逆变器组成。整流器采用不可控三相全桥式整流电路。滤波器采用两个电解电容和一个电感组成Ⅱ型滤波器滤波和无源功率因数校正。逆变器主要由PWM控制器SG3525A控制四个IGBT的开通和关断，实现DC-AC的转换。
设计中采用的芯片主要是PWM控制器SG3525A和光耦合驱动电路HCPL-316J。设计过程中程充分利用了SG3525A的控制性能，具有宽的可调工作频率，死区时间可调，具有输入欠电压锁定功能和双路输出电流。由于HCPL-316J具有快的开关速度（500ns），光隔离，故障状态反馈，可配置自动复位、自动关闭等功能，所以选择其作为IGBT的驱动。
对原理样机的调试结果表明，所完成的设计实现了设计任务规定的基本功能。此外，为了满足不同器件对功率需要的要求，设计了功率可调。这部分超出了设计任务书规定的任务。(induction heating with high heating efficiency, speed and good controllability and easy to mechanization. the advantages of automation, in melting, casting, bending, forging, welding and surface heat treatment and other industries have been widely employed. According to the design tasks for the design of the program design, design corresponding to the hardware circuit, Development of 20 KW induction heating power. The design of induction heating power IGBT used as a switching device, which can work in 10 Hz- 10 kHz frequency band. It consists of rectifier, filter, and the inverter components. Controlled Rectifier not use the entire three-phase bridge rectifier circuit. 2 filter used an electrolytic capacitor and inductor components II-type filter and passive PFC. Inverter mainly by the PW)
