用DeleteService之后服务只是作了一个删除标志，再创建服务就会失败，返回ERROR_SERVICE_MARKED_FOR_DELETE。如果直接删除注册表，windows的服务管理器还是会显示那个服务（还存在哪里了？），只是属性都没有所以我现在是先DeleteService，然后删除注册表不知道windows是否提供了API彻底的删除服务？ps，关于CreateService返回ERROR_SERVICE_MARKED_FOR_DELETE的这个问题，我看网上的例子似乎都没有说明这个问题，真是没这个问题码？
或者导放 a.exe的输出节调用

看你的代码关键似乎是这句：
CloseServiceHandle(m_svc); //删除Service后，最好再调用CloseServiceHandle,以便立即从数据库中移走此条目。但是我的代码里面也确实关闭了SC_HANDLE，但是注册表还是存在，再建服务就会返回服务已经被标记为删除的错误void SUnInstall(SC_HANDLE hSCDB)
{
try
{
SC_HANDLE h1=OpenService(hSCDB,SERVICE_NAME,SERVICE_ALL_ACCESS);
if(!h1)
{
throw "打开服务失败。";
}
SERVICE_STATUS_PROCESS stStatus;
if(QueryServiceStatusEx(h1,SC_STATUS_PROCESS_INFO,(BYTE*)&stStatus,sizeof(stStatus),NULL))
{
SERVICE_STATUS stStatus2;
ControlService(h1,SERVICE_CONTROL_STOP,&stStatus2);
}
else
{
SERVICE_STATUS stStatus2;
ControlService(h1,SERVICE_CONTROL_STOP,&stStatus2);
}
if(!DeleteService(h1))
{
CloseServiceHandle(h1);
throw "删除服务失败";
}
CloseServiceHandle(h1);
}
catch (const char* e1)
{
MessageBox(NULL,e1,"错误",MB_OK);
}
catch (...)
{
}
}
hscDB在函数外面打开、关闭
