[问题]WDM 新手的第一个程式

依书上范例 ( Developing Windows NT Device Drivers )
做出了 hello.sys
在registry中设定
\\register\\machine\\system\\currentcontrolset\\services\\HELLO
Type = REG_DWORD 0x00000001
Start = REG_DWORD 0x00000003
Group = Extended  base
ErrorControl  =  REG_DWORD  0x00000001
写个测试程式, 也是书上范例, 却出现
Can\'t get a handle to HELLO device 是测试程式印出的讯息.
请问各位先进, 我是那里出错呢?
以下是程式码

先确认你的驱动是否已经正确安装！
