首先先创建一个控制台程序，或者win32程序，都没关系。因为后台服务是看不到界面的。 服务程序应具有这样的功能： 一个服务主函数，注册服务控制句柄，启动要运行的代码。 二是服务控制函数，注册给系统，提供对服务管理程序SCM的响应，就是我的电脑-》管理里面的服务，不是有开始，停止，暂停这些功能么，这个函数就是对这个响应，停止的时候就做退出清理工作，关闭进程。 就两个函数而已。一般是ServiceMain 和ServiceCtrlHandler 这就是服务的全部必须代码了。 然后为什么别人的服务还有很多函数呢，什么 InstallService DeleteService之类的。 因为服务需要安装呀，一般一个程序写在一起，方便一点，但安装服务不是服务必须的，这必须理清楚，服务只需要一个主函数就行，安装卸载可以由其他的程序安装卸载。比如sc 或者直接操作注册表。 下面就是贴代码了 // GtServ.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include "Windows.h" #include "LogWriter.h" SERVICE_STATUS m_ServiceStatus; SERVICE_STATUS_HANDLE m_ServiceStatusHandle; BOOL bRunning=true; void WINAPI ServiceMain(DWORD argc, LPTSTR *argv); void WINAPI ServiceCtrlHandler(DWORD Opcode); BOOL InstallService(); BOOL DeleteService(); //log类 CLogWriter log("D:\\log.TXT"); void DoTask() { } int _tmain(int argc, _TCHAR* argv[]) { if(argc>1) { if( wcscmp(argv[1],L"-i")==0) { if(InstallService()) printf("\n Service Installed Sucessfully\n"); else printf("\n Service has been installed\n"); } else if(wcscmp(argv[1],L"-d")==0) { if(DeleteService()) printf("\n Service UnInstalled Sucessfully\n"); else printf("\nInstalled Easin Central Service Not Found\n"); } else { printf("\nUnknown Switch Usage\nFor Install use Servicetest -i\nFor UnInstall use Servicetest -d\n"); } } else { SERVICE_TABLE_ENTRY DispatchTable[]={{L"GtServ",ServiceMain},{NULL,NULL}}; StartServiceCtrlDispatcher(DispatchTable); } return 0; } void WINAPI ServiceMain(DWORD argc, LPTSTR *argv) { // DWORD status; // DWORD specificError; m_ServiceStatus.dwServiceType = SERVICE_WIN32; m_ServiceStatus.dwCurrentState = SERVICE_START_PENDING; m_ServiceStatus.dwControlsAccepted = SERVICE_ACCEPT_STOP; m_ServiceStatus.dwWin32ExitCode = 0; m_ServiceStatus.dwServiceSpecificExitCode = 0; m_ServiceStatus.dwCheckPoint = 0; m_ServiceStatus.dwWaitHint = 0; m_ServiceStatusHandle = RegisterServiceCtrlHandler(L"GtServ",ServiceCtrlHandler); if (m_ServiceStatusHandle == (SERVICE_STATUS_HANDLE)0) { return; } m_ServiceStatus.dwCurrentState = SERVICE_RUNNING; m_ServiceStatus.dwCheckPoint = 0; m_ServiceStatus.dwWaitHint = 0; if (!SetServiceStatus (m_ServiceStatusHandle,&m_ServiceStatus)) { } bRunning=true; while(bRunning) { Sleep(3000); //Place Your Code for processing here....
