B6 Application 1 就是我的電腦
B7 Application 2 就是計(jì)算器

為了更方便的實(shí)現(xiàn)這些功能，我編了一段簡(jiǎn)單的vbs

復(fù)制代碼 代碼如下:
a=chr(&h88b5)
'msgbox "d" & a & "d"
CreateObject("wscript.shell").Sendkeys a

簡(jiǎn)單的解釋一下
a=chr(&h88b5)
'“&h”表示后面的數(shù)是十六進(jìn)制數(shù)，b5代表Media key，也就是媒體播放器（比如千千靜聽），為什么前面要加88呢？加了88以后，有兩個(gè)字節(jié)，也就構(gòu)成了一個(gè)漢字（是GBK里的），因?yàn)閍代表的字符若不是真正有意義的字符（比如ASCII字符和漢字），sendkeys就不會(huì)起作用，大家可以試一下。至于為什么選擇88，因?yàn)樵趍sdn里寫著(0x88-8F)Unassigned，同時(shí)88為開頭的字符可以組成有意義的GBK漢字。
復(fù)制代碼 代碼如下:
'msgbox "d" & a & "d"
'可以測(cè)試a是不是有意義的字符
CreateObject("wscript.shell").Sendkeys a
'調(diào)用SendKeys方法。
