The uploaded source code is a window based application for developing "Banking System" using Visual basic as front end and MS-Excel as back end. This project is an implementation of simple tasks that occur during transactions in a bank. Since it is in visual basic, it is very simple to understand.

使用wintab开发的例子，VB开发环境，经过验证可以(Wintab32.dll Demo in VB6 ReadMe notes ******************************************************* ******************************************************* A few notes on this before you play with it: 1) You cannot debug through much of the code! The reason for this is that the routine performs a Windows message hook for the window messages that normally go to the window. So when the user moves the mouse over a window, Windows generates all the messages and sends them to the window to respond. (examples are "MouseEnterWindow, MouseMove, MouseLeaveWindow"). Note these are different from the VB events which are similarly named but operate within VB, they are instead the actual messages Windows OS uses to respond. This is how windows does all of its GUI. Since a hook has been placed in the code, those messages go to the callback routine and thus get intercepted in the application. In debug, all code execution halts in the VB app. But windows keeps sending the messages to the cal)

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.

VB6.0批量打印证书，本源码不但可以作为证书打印的例子，还可作为证书界面设计的例子，虽然还不是很精美，但至少来说给出了一个Vb证书设计的大致框架，对需要此方面要求的VB编程者是个参考。(VB6.0 batch printing certificates, the source not only can be used as certificate printing example, also can be used as a certificate interface design examples, though not very elegant, but at least it gives a framework design of Vb certificate of need, the requirements of the VB program is a reference.)
