读文件，.ini操作

小生课程设计作业，做的不是非常完善，还请各位大神指点。。。分为管理员端与学生端。

用于计算字符串MD5值-used to calculate the value of the string MD5

全局函数使用起来很方便，不需要很多的包含头文件，在每种类中都可以用。可是，他的实现上也要注意一些细节，本实例就是出于这一目的，给出简单事例，教初学者如何使用全局类的方法。 希望对大家有所帮助。 -It is very convenient by using global function because it needn t include many head files and can be used in almost every class.But when you use it you should pay attention on some details,and the example given here will introduce beginners some methods on how to use global class.I hope it will be usefull for you

这是一个SDK程序。本程序跟踪显示鼠标的坐标位置，同时，若有鼠标操作，可在窗口标题栏中显示操作信息，要是在窗口客户区中进行双击，就会在双击位置点上显示位置信息。此外，客户中还有两个位图，当鼠标移动到位图上时，就会改变为自己定义的光标。该程序适合Win32编程初学者，内含大量的中文注释。-This is a SDK procedure. This program tracking demonstrates the coordinates position of the mouse, at the same time, demonstrate the operation information in the window title block if the mouse has operation. if double-clicks in the window customer area ,can demonstrates the positional information of the double-click position. In addition, in the customer also has two units places charts, when the mouse moves arrives on the chart, can change the cursor which defines as oneself. This procedure suits the Win32 programming beginner, contains the massive Chinese annotation.

接收单元，我们采用的原理和调频收音机原理一样。图3为接收电路，以专用调频接收模块IC1 TDA7021T为核心，经解调后的音频信号从脚输出，送到IC2 LM386作功率放大，推动耳机发声。三极管BG9018等组成高频放大级，以提高接收灵敏度。调节可调电容器C23可以改变接收频率，使其对准发射机的发射频率。-Receiving unit, we have adopted the principle and the principle of like FM radio. Figure 3 for the receiver circuit to a dedicated IC1 TDA7021T FM receiver module as the core, after demodulation of the audio signal after the output from the feet, to make IC2 LM386 power amplifier, and promote sound headphones. BG9018 triode composed of high-frequency amplification level in order to improve receiver sensitivity. Conditioning adjustable capacitor C23 can change the receiver frequency so that it fired at the transmitter frequency.
