windows服务和注册表简单编程例子

一：注册表的操作编程



#include <windows.h>
#include <iostream>
#include <cstdlib>
using namespace std;

int main()
{
    HKEY hKey;     
    LPCTSTR lpRun = "Software\_MyTest";
    DWORD state,dwtype,sizeBuff;
    long lRet;
    char reBuff[10] = {0};


    /*创建键***************************************************************************/
    ////创建键
    lRet = RegCreateKeyEx(HKEY_CURRENT_USER,lpRun,0,NULL,0,0,NULL,&hKey,&state);
    if(lRet == ERROR_SUCCESS)
    {
       if(state == REG_CREATED_NEW_KEY)
           cout<<"表项创建成功"<<endl;
    
       //关闭键
       RegCloseKey(hKey);
    }


    /*打开/修改键值********************************************************************/
    ////打开键
    // lRet= RegOpenKeyEx(HKEY_CURRENT_USER, lpRun, 0, KEY_WRITE, &hKey);
    // if(lRet == ERROR_SUCCESS) 
    // {     
    //    //创建或者修改键值
    //    RegSetValueEx(hKey, "test",0,REG_SZ,(BYTE *)"success",10);
       
    //    //关闭键    
    //    RegCloseKey(hKey);
    // }


    /*读取键值*************************************************************************/
    ////打开键
    // lRet= RegOpenKeyEx(HKEY_CURRENT_USER, lpRun, 0, KEY_READ, &hKey);
    // if(lRet == ERROR_SUCCESS) 
    // {
    //    sizeBuff = sizeof(reBuff);
       
    //    //读取键值
    //    if(RegQueryValueEx(hKey,"test",0,&dwtype,(BYTE*)reBuff,&sizeBuff) == ERROR_SUCCESS)
    //        cout<<reBuff<<endl;
       
    //    //关闭键
    //    RegCloseKey(hKey);
    // }


    /*删除键值************************************************************************/
    ////打开键
    // lRet = RegOpenKeyEx(HKEY_CURRENT_USER, lpRun, 0, KEY_WRITE, &hKey);    
    // if(lRet==ERROR_SUCCESS)
    // {
    //    //删除键
    //    RegDeleteValue(hKey,"test");
       
    //    //关闭键
    //    RegCloseKey(hKey);
    // }


    /*删除键**************************************************************************/
    // RegDeleteKey(HKEY_CURRENT_USER,lpRun);

    // system("pause");
}

二：windows服务编程的基本框架

// ConsoleApplication1.cpp: 定义控制台应用程序的入口点。
//main.cpp

#include "stdafx.h"



CHAR * SERVICE_NAME = "testService";
SERVICE_STATUS_HANDLE serviceStatusHandle;
SERVICE_STATUS ServStatus;
static BOOL shutdownSVC = FALSE;
static FILE *logfile = NULL;
TCHAR cTimeString[30] = _T("");
time_t currentTime;

VOID Handler(DWORD controlcode)
{
    switch (controlcode)
    {
    case SERVICE_CONTROL_STOP:
        shutdownSVC = TRUE;
        ServStatus.dwCurrentState = SERVICE_STOPPED;
        SetServiceStatus(serviceStatusHandle, &ServStatus);
        break;
    case SERVICE_CONTROL_PAUSE:
        break;
    case SERVICE_CONTROL_CONTINUE:
        break;
    case SERVICE_CONTROL_INTERROGATE:
        break;
    case SERVICE_CONTROL_SHUTDOWN:
        break;
    }
    return;
}

VOID ServiceMain(DWORD argc, LPTSTR * argv)
{
    ServStatus.dwServiceType = SERVICE_WIN32_OWN_PROCESS;
    ServStatus.dwCurrentState = SERVICE_START_PENDING;
    ServStatus.dwControlsAccepted = SERVICE_ACCEPT_STOP | SERVICE_ACCEPT_SHUTDOWN | SERVICE_ACCEPT_PAUSE_CONTINUE;
    ServStatus.dwWin32ExitCode = NO_ERROR;
    ServStatus.dwServiceSpecificExitCode = 0;
    ServStatus.dwCheckPoint = 0;
    ServStatus.dwWaitHint = 2000;

    serviceStatusHandle = RegisterServiceCtrlHandler((LPCWSTR)SERVICE_NAME, (LPHANDLER_FUNCTION)Handler);

    ServStatus.dwCurrentState = SERVICE_RUNNING;
    SetServiceStatus(serviceStatusHandle, &ServStatus);

    FILE *fp;
    fopen_s(&fp, "F:\test.c", "w");
    fprintf(fp, "%s", "#include <stdio.h>
");
    fprintf(fp, "%s", "int main(void)
");
    fprintf(fp, "%s", "{
");
    fprintf(fp, "%s", "printf("hello World!");
");
    fprintf(fp, "%s", "}
");
    fprintf(fp, "%s", "return 0;
");
    fclose(fp);

}

int main()
{

    SERVICE_TABLE_ENTRY serviceTable[] =
    {
        { (LPWSTR)SERVICE_NAME,(LPSERVICE_MAIN_FUNCTION)ServiceMain },
        { NULL,NULL }
    };
    BOOL success;
    success = StartServiceCtrlDispatcher(serviceTable);
    if (!success)
        ExitProcess(GetLastError());
    return 1;
}
