遍历系统服务和创建服务

/Files/tt_mc/catchser.rar这段代码是遍历系统中的服务，看里面是否有“HOOK”这个服务，如果没有就创建：

#include "StdAfx.h"
#include <string>
#include "ServConfig.h"
using namespace std;

int CatchSer()
{
    
    SC_HANDLE hSCM = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
    if ( !hSCM ) 
    {
        //  MessageBoxEx(NULL,_TEXT("测试文本"),_TEXT("测试标题"),MB_OK,0);
    }
    CServItem *pServHeader = NULL, *pServPre = NULL, *pServNext = NULL;
    LPENUM_SERVICE_STATUS pServStatus = NULL;
    DWORD dwBytesNeeded = 0, dwServCound = 0, dwResume = 0, dwRealBytes = 0;
    BOOL bRet = EnumServicesStatus(hSCM, SERVICE_WIN32, SERVICE_STATE_ALL, NULL, 0, &dwBytesNeeded, &dwServCound, &dwResume);
    if ( !bRet && GetLastError() == ERROR_MORE_DATA ) 
    {
        dwRealBytes = dwBytesNeeded;
        pServStatus = new ENUM_SERVICE_STATUS[dwRealBytes+1];
        ZeroMemory(pServStatus, dwRealBytes+1);
        bRet = EnumServicesStatus(hSCM, SERVICE_WIN32, SERVICE_STATE_ALL, pServStatus, dwRealBytes, &dwBytesNeeded, &dwServCound, &dwResume);
        if ( !bRet ) 
        {
            CloseServiceHandle(hSCM);
            return NULL;
        }
    }
    else
    {
        CloseServiceHandle(hSCM);
        return NULL;
    }
    string sh1,sh2 ;
    for( DWORD dwIdx = 0; dwIdx < dwServCound; dwIdx++ ) 
    {
        char a[100];
        strcpy(a,pServStatus[dwIdx].lpDisplayName);
        sh1 = a;
        if(sh1=="hook")
        {
            sh2="hook";
        }
    }

        SC_HANDLE service=NULL;
        if((manager=OpenSCManager(NULL,NULL,SC_MANAGER_CREATE_SERVICE))==NULL)
        {
            printf("OpenSCManager Error");
        }
        service=CreateService(
            manager,name,info, 
            SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS, 
            SERVICE_AUTO_START, SERVICE_ERROR_NORMAL,
            path, 0, 0, 0, 0, 0 );
        if(service)
            printf("服务创建成功\n\n");
        else
            printf("服务创建失败\n\n");
        CloseServiceHandle(service);
        CloseServiceHandle(manager);
    }
}
