C++写的服务中的dll的问题，跪求大神
写的服务中要调用一个DLL，然后这个DLL里又要调用另一个DLL，我测试了下，第一个DLL能加载也有功能，但是DLL里面的DLL能加载但是没有运行其功能。代码如下。
C/C++ code
#include "stdafx.h"
#include <Windows.h>
#include <fstream>
using namespace std;

//ksrecord
typedef int(* lpHookCNProc)(void); //宏定义函数指针类型
HINSTANCE hDll; //DLL句柄

BOOL IsInstalled();
BOOL Install();
void Init();
TCHAR szServiceName[] = _T("测试");
SERVICE_STATUS testServiceStatus;
SERVICE_STATUS_HANDLE testServiceStatusHandle;
void SvcDebugOut(LPSTR String,DWORD Status);
void WINAPI testServiceCtrlHandler(DWORD opcode);
void WINAPI testServiceStart(DWORD argc,LPTSTR *argv);
//DWORD testSerciveInitialization(DWORD argc,LPTSTR *argv,DWORD *specificError);
VOID ServerProgram(DWORD, LPTSTR *); //服务主程序   


int _tmain(int argc, _TCHAR* argv[])
{
    Init();
    SERVICE_TABLE_ENTRY DispatchTable[] = 
    {
        {szServiceName,(LPSERVICE_MAIN_FUNCTION)testServiceStart},
        {NULL,NULL}
    };
    Install();
    if(!StartServiceCtrlDispatcher(DispatchTable))
    {
        SvcDebugOut("[TESTSRV_SERVICE]StartServiceCtrlDispatcher %ld\n",GetLastError());
    }
    return 0;
}

void WINAPI testServiceStart(DWORD argc,LPTSTR *argv)
{
    DWORD status;
    DWORD specificError = 0;
    testServiceStatus.dwServiceType = SERVICE_WIN32_OWN_PROCESS;
    testServiceStatus.dwCurrentState = SERVICE_START_PENDING;
    testServiceStatus.dwControlsAccepted 
        = SERVICE_ACCEPT_STOP|SERVICE_ACCEPT_PAUSE_CONTINUE;

    testServiceStatusHandle = RegisterServiceCtrlHandler(
        szServiceName,
        testServiceCtrlHandler);
    if(testServiceStatusHandle == (SERVICE_STATUS_HANDLE)0)
    {
        SvcDebugOut("[TESTSRV_SERVICE]RegisterServiceCtrlHandler failed %d\n",GetLastError());
        return;
    }
    testServiceStatus.dwWin32ExitCode = S_OK;
    testServiceStatus.dwCheckPoint = 0;  
    testServiceStatus.dwWaitHint = 0;  
    testServiceStatus.dwCurrentState = SERVICE_RUNNING;
    if(!SetServiceStatus(testServiceStatusHandle, &testServiceStatus))
    {
        status = GetLastError();

    SetServiceStatus(testServiceStatusHandle, &testServiceStatus);
    return;
}

void ServerProgram(DWORD argc, LPTSTR *argv)
{
    lpHookCNProc SetKBHookCn; //函数指针
    hDll = LoadLibrary("KRecorder.dll");//krecorder中还调用了一个Dll
    if (hDll != NULL)
