calculator

可以方便的进行三次以内方幂求和公式的自动推导 此代码为独创(Can easily be a power of less than three times the automatic derivation of the summation formula for the original code)

一个反褶积的VC++例子,简单明了,很适合刚刚开始学习信号分析的人(A deconvolution of VC++ Example simple, it is suitable for signal analysis has just begun to study people)

可以实现模拟键盘，驱动级的。可以当普通键盘一样使用(Can realize analog keyboard, driver class. Like an ordinary keyboard can be used)

一个很好的VB时钟源码，有时针，分针，秒针，源码测试通过(A good source VB clock, hour, minute, second hand, source testing by)

通讯录中的每一个信息包括姓名（规定字节数为15个）、电话（规定字节数为15个）和工作单位（最大字节数为30个）等信息。(Each information including the name of the mail list ( specified byte number 15 ), phone ( specified byte number 15 ) and work units ( the maximum number of bytes to 30 ) and other information.)

vc++将汉字转换成拼音的程序源代码，非常有意思，它不单纯转换为拼音，而且还可以设置分隔符，按规则转换：全部转换成大写、全部转换成小写、将首字母大写，还可以转换为现在流行的拼音首字母简写，也就是只取拼音首字母，按大写或小写提取，看来确实非常有意思也非常实用哦。(vc++ will be converted into Chinese characters spelling the source code, very interesting, it does not simply converted to Pinyin, but also can be set separators in accordance with the rules of conversion: the conversion of all upper case, all converted to lowercase to uppercase the first letter, but also can be converted to Pinyin is now the first letter of the popular shorthand, that is, only the first letter of alphabet, based on extraction of upper or lowercase, it seems very interesting indeed Oh also very practical.)

说明：  以3月5日为例，应该先把前两个月的加起来，然后再加上5天即本年的第几天，特殊 　　　　　　 情况，闰年且输入月份大于3时需考虑多加一天。(To March 5, for example, should the first two months of the combined first and then add the 5th day of the first few days of this year, special circumstances, a leap year and enter the 3 months to consider more than one day.)

软件测试功能，使用uft进行的自动化测试功能(programing test,for auto programing test by UFT)

说明：  在EVC4.0环境下，设置串行通讯端口程序例(The EVC4.0 environment, set up procedures for cases of serial communication ports)

此代码的功能是：用列表显示系统正在运行的程序,用visual basic 编写完成,()
