　　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。-writer in the development of county-level SCADA process, encountered a power system to draw a diagram of the problem. The electric system diagram of a more complex map some special symbols, symbols like transformers, switch symbol, and so on, using common programming methods to map more difficult, therefore, I used the C language development of a hand-drawn power system diagram of a keyboard mapping procedures, the use of the program was produced by a diagram meet the demands of users, to good effect.

EAN条码字体的解码算法 经常发现用PB的开发人员在问为什么用EAN的字体打出来的条码扫描枪无法扫描 其实受EAN的编码规格的限制，EAN的字体是不能直接使用的，EAN13的编码规格就不 多说了，下面给出两个函数可把条码转换为EAN字体可识别的字符串(分别对应EAN13和EAN8两种编码)-EAN barcode font decoding algorithms are often found with the development of PB in the question why the fonts EAN bar code scanning to fight out of the gun can not scan a matter of fact by the EAN coding specification limit, EAN fonts can not be directly used, EAN13 of coding specifications do not say, and given the following two functions can be converted to EAN barcode fonts can be identified by the string (corresponding to two coding EAN13 and EAN8)
