B6 Application 1 就是我的电脑
B7 Application 2 就是计算器
为了更方便的实现这些功能，我编了一段简单的vbs
a=chr(&h88b5)
'msgbox "d" & a & "d"
CreateObject("wscript.shell").Sendkeys a
简单的解释一下
a=chr(&h88b5)
'“&h”表示后面的数是十六进制数，b5代表Media key，也就是媒体播放器（比如千千静听），为什么前面要加88呢？加了88以后，有两个字节，也就构成了一个汉字（是GBK里的），因为a代表的字符若不是真正有意义的字符（比如ASCII字符和汉字），sendkeys就不会起作用，大家可以试一下。至于为什么选择88，因为在msdn里写着(0x88-8F)Unassigned，同时88为开头的字符可以组成有意义的GBK汉字。
'msgbox "d" & a & "d"
'可以测试a是不是有意义的字符
CreateObject("wscript.shell").Sendkeys a
'调用SendKeys方法。
