OpenService()打开服务总出错

[cmh360]

代码段：

DWORD dwErr = 0;

//检测服务初始化
memset(&m_SvcStatus, 0x00, sizeof(SERVICE_STATUS));
// 打开服务管理对象
m_hSC = OpenSCManager(NULL, /*NULL*/SERVICES_ACTIVE_DATABASE , /*GENERIC_READ*/SC_MANAGER_ALL_ACCESS);
if (m_hSC != NULL)
{
m_hSvc = OpenService(m_hSC, SERVICE, /*GENERIC_READ*/GENERIC_ALL);
dwErr = GetLastError();
}

问题：

OpenService（）打开有的windows的服务，有的却报1060， errlook说是“指定的服务并未以已安装的服务存在。 ”
没有弄明白为什么？

真没有人知道？

服务一开始Open失败很正常，你先QueryServiceStatusEx下，然后StartService

schService = OpenService( 
        schSCManager,         // SCM database 
        szSvcName,            // name of service 
        SERVICE_ALL_ACCESS);  // full access 
 
    if (schService == NULL)
    { 
        printf("OpenService failed (%d)\n", GetLastError()); 
        CloseServiceHandle(schSCManager);
        return;
    }    

    // Check the status in case the service is not stopped. 

    if (!QueryServiceStatusEx( 
            schService,                     // handle to service 
            SC_STATUS_PROCESS_INFO,         // information level
            (LPBYTE) &ssStatus,             // address of structure
            sizeof(SERVICE_STATUS_PROCESS), // size of structure
            &dwBytesNeeded ) )              // size needed if buffer is too small
    {
        printf("QueryServiceStatusEx failed (%d)\n", GetLastError());
        CloseServiceHandle(schService); 
        CloseServiceHandle(schSCManager);
        return; 
    }

    // Check if the service is already running. It would be possible
    // to stop the service here, but for simplicity this example just returns. 

    if(ssStatus.dwCurrentState != SERVICE_STOPPED && ssStatus.dwCurrentState != SERVICE_STOP_PENDING)
    {
        printf("Cannot start the service because it is already running\n");
        CloseServiceHandle(schService); 
        CloseServiceHandle(schSCManager);
        return;

    // Wait for the service to stop before attempting to start it.

[cmh360]

schService = OpenService(
schSCManager, // SCM database
szSvcName, // name of service
SERVICE_ALL_ACCESS); // full access

问题是，我这个都是失败的，无法往下进行了

[cmh360]

可能系统有的服务是不能打开的

楼主,没分啊...所以我选择沉默.
