请教 .NET　Service装载问题

在Windows CE 4.2上做一个service, 修改了注册表,
Registry settings:
"Dll"="Service.dll"
Index=3
Order=8
"Prefix"="AEG"
Flags =2
Keep=1
Context=1;
"DisplayName"="AEG Service"

系统启动时调用 xxx_Init, xxx_IOControl (IOCTL_SERVICE_QUERY_CAN_DEINIT), 返回TRUE, Out Buffer 也设置成非0值, 可系统仍然调用 xxx_Deinit 而退出. 请教如何才能保证 service 驻留? 除了 xxx_Init, xxx_IOControl, xxx_Deinit之外, 还有什么函数会影响系统装载service? 谢谢.

The document doesn't match services.exe.  When you return a nonzero value and TRUE, services.exe will call xxx_Deinit function and unload the DLL file. If return value is TRUE and set Out buffer to 0, DLL won't be unloaded.

你不是把out buffer设成非0了吗？你引用的帮助不是说设成0才不被unload吗？
