C编写Windows服务程序学习

本文主要讲述Windows服务程序的编写，分享完整代码，初学者可以直接编译通过，并查看结果，基本知识及步骤读者可以参考网络中其他文章。下面是Windows服务程序的全部代码，最后是安装服务。

#include <windows.h>
#include <stdio.h>

#define SLEEP_TIME 5000
#define LOGFILE "E:\\myservice.txt"
#define SERVICE_NAME "MYSERVICE"

SERVICE_STATUS ServiceStatus; //服务状态
SERVICE_STATUS_HANDLE hStatus; //服务状态句柄

void WINAPI ServiceMain(int argc, char **argv); //服务主程序
void WINAPI ControlHandler(DWORD request); //服务控制程序

boolean running = TRUE;

int WriteToLog(char *str)
{
FILE *log;
fopen_s(&log,LOGFILE, "a+");
if (log == NULL)
{
return -1;
}
fprintf_s(log, "%s\n", str);
fclose(log);
return 0;
}

void WINAPI ServiceMain(int argc, char **argv)
{
WriteToLog("Monitoring started.");

ServiceStatus.dwServiceType = SERVICE_WIN32_OWN_PROCESS;
ServiceStatus.dwCurrentState = SERVICE_START_PENDING;
ServiceStatus.dwControlsAccepted = SERVICE_ACCEPT_SHUTDOWN | SERVICE_ACCEPT_STOP;
//在本例中只接受系统关机和停止服务两种控制命令
ServiceStatus.dwWin32ExitCode = 0;
ServiceStatus.dwWaitHint = 0;
ServiceStatus.dwCheckPoint = 0;
ServiceStatus.dwServiceSpecificExitCode = 0;

//注册服务控制处理函数
hStatus = RegisterServiceCtrlHandler(SERVICE_NAME, ControlHandler);

//如果注册失败
if (!hStatus)
{
WriteToLog("RegisterServiceCtrlHandler failed");
return;
}

WriteToLog("RegisterServiceCtrlHandler success");

//向SCM 报告运行状态
ServiceStatus.dwCurrentState = SERVICE_RUNNING;
SetServiceStatus(hStatus, &ServiceStatus);

//下面就开始任务循环了，你可以添加你自己希望服务做的工作
char str[80] = { 0 };
while (running)
{
  strcpy_s(str,80,"this is a test");
  Sleep(1000);
  WriteToLog(str);
}

WriteToLog("service stopped");

}

void WINAPI ControlHandler(DWORD request)
{
switch (request)
{
case SERVICE_CONTROL_STOP:
  running = FALSE;
  ServiceStatus.dwCurrentState = SERVICE_STOPPED;
  WriteToLog("service stopped");
  break;
case SERVICE_CONTROL_SHUTDOWN:
  running = FALSE;
  ServiceStatus.dwCurrentState = SERVICE_STOPPED;
  WriteToLog("service shutdown");
  break;
default:
  break;
}

SetServiceStatus(hStatus, &ServiceStatus);
}

int main()
{
SERVICE_TABLE_ENTRY ServiceTable[] = { { SERVICE_NAME, (LPSERVICE_MAIN_FUNCTION)ServiceMain }, { NULL, NULL } };

// 启动服务的控制分派机线程
StartServiceCtrlDispatcher(ServiceTable);

return 0;
}

2.安装Windows服务

由于本机用户权限问题，我建立了4个bat文件，分别是Install.bat（创建服务命令），Uninstall.bat（卸载服务命令，重启有效），Start.bat（启动服务命令），Stop.bat（停止服务命令），4个bat文件对应下面4个命令：sc create myserve binpath= E:\MyService\Debug\MyService.exe（exe文件地址）；sc delete myserve；sc start myserve；sc stop myserve，用户可以鼠标右键选择以管理员身份运行，这样可以解决权限问题。
