[VC/MFC] 2(2) DL : 0: C语言编写键盘画图程序笔者在开发县级电网调度自动化系统的过程中，碰到一个要绘制电力系统一次接线图的问题。由于电力系统一次接线图比较复杂，图上有一些特殊的符号，象变压器符号、开关符号等等，用一般的编程方法来绘制比较困难，因此，笔者用C语言开发了一个手工绘制电力系统一次接线图的键盘绘图程序，使用该程序绘制的一次接线图符合用户需求，效果良好。使用方法程序中定义了几个特殊键： "Ｖ”：画笔提起 "Ｗ”：开始画图 "Ｒ”：开始擦图 "Ｓ”：当前图形存入文件 "Ｅ”：调出已有文件 "Ｃ”：画圆程序一运行，屏幕上出现一个黄色的边框来设定画图的区域，区域中间出现提起的画笔符号，当按下“Ｗ”键时，画笔符号变为，此时可移动方向键（上、下、左、右、左上、左下、右上、右下）来画图；当按下“Ｒ”键时，画笔符号变为，此时可移动方向键来擦图；在画图过程中，按下“Ｃ”键，可画出一个半径为20个象素点的圆；当结束画图时，按下“Ｓ”键，将画好的图形存盘；按下“Ｅ”键可调出已有的图形进行编辑。-C language keyboard paint program I developed at the county level in the process of dispatching automation system, the encounter of a power system to draw a wiring diagram of the problem. A wiring diagram of the power system more complex, the map has some special symbols, as transformer symbol, switch symbols, etc., with general programming is difficult to draw, so I use the C language has developed a hand-drawn a power system keyboard wiring diagram drawing program, use the program draw a wiring diagram to meet client requirements effectively. Use Program defines several special keys: "V": brush filed "W": Start Paint "R": Start cleaning chart "S": the current graphics into documents "E": call up existing files "C": draw a circle A running program on the screen a yellow border to set the drawing area, the regional center there mention of the brush symbol, when you press the "W" key, sign into the brush, then you can move the arrow keys (up, down , left, rig
