- 单片机因其体积小、功能强、价格低廉而得到广泛应用。这个单片机电子琴，利用AT89S52的功能设计电子琴电路，仅仅用AT89L52单片机设计微型电子琴的方法,仅需AT89L52最小系统,扩展一组小键盘（这里以4×4键盘为例,可按需要扩展）,再加一片LM386做音频小功放,输出到扬声器。电源可由12V直流电压或者三节5号电池提供。电路简单，元器件少，很容易制作。-SCM because of its small size, powerful functions, low cost and widel

- 其实原理就是捕获屏幕画面然后再把图像传给客户机。原理很简单： 1、先利用hdc=GetWindowDC(NULL) 得到桌面的hdc 2、memhdc=CreateCompatibleDC(hdc) 根据桌面的hdc创建一个和屏幕相同的内存DC 3、StretchBlt(memhdc,0, 0, nWid,nHei, hdc, 0, 0,nWid,nHei, SRCCOPY) ，把屏幕的图像复制到内存DC这时你已经在内存中得到了屏幕的图像了。这是设备相关的DDB图像，如果希望转换成设
