我以CreateService(),StartService()加载,机子一下就黑屏重启了
请高手别嫌我菜,给找找问题

你可以用softice自带的drivermonitor加载启动试试，如果还启动部成功，那就是你的DriverEntry有问题了

tooflat可以把你的CreateService和StartService的启动服务程序贴上来吗？我CreateService和OpenService都正常就是一StartService返回值就是error

可以给我一份例子吗？我的QQ：37376159，或者邮箱：ljkong323@hotmail.com，我调不通呀，再问一个问题，看你们说要用什么CreateSevice，怎么用呢？

我在3楼的例子就可以，再把12楼的意见加上就完全了

到底有人调通了吗，上来说一下

到底有人调通了吗，上来说一下

大家关注啊

我加载了，或者关机的时候蓝屏，或者安装失败，大家有什么好建议。

最新的版本到底效果如何？

那过滤CDROM class就可以吗 ?

用device tree看了一下，
cdrom0上面挂了一个redbook，redbook上面挂了我们的过滤驱动，
但是cdfs直接把irp发给redbook了，没有发给我们的过滤驱动，
所以光驱还是可以打开。

如果光驱里面有盘, 那么多数情况下文件系统已经MOUNT好了, 你这时再去做磁盘过滤当然没用. 详情见 ifsddk -> ifs documents -> ifs kit -> design guide -> file system fundamentals -> mounting a volume -> how the volume is mounted -> note

tooflat，你三楼的程序我试了一下，可以锁住光驱阿，为什么后面又要改其它的呢？

修改了dj_ukyo的代码，增加了一些错误处理和对IRP_POWER的支持，启动起来没有问题，但是光驱还是可以打开。

不知道什么原因。

好像格式有问题，我打包上传一个

一到startservice()就黑屏重启了,意味着你的DRIVERENTRY有问题,你下断点看看是什么问题.

请调试成功的兄弟把代码贴出来看看啊!
