Question

我使用C ++创建了一个Win32服务并成功安装到服务中。

现在，当我尝试从Services.msc启动服务时，我收到错误：无法启动本地计算机上的服务。错误2：系统找不到指定的文件。

以下是我在服务入口点中定义的代码段：

#include "stdafx.h"
#include "iostream"
#include "Windows.h"
#include "Winsvc.h"
#include "time.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();
void main(int argc, char* argv[])
{

  if(argc>1)
  {
    if(strcmp(argv[1],"-i")==0)
    {
      if(InstallService())
        printf("\n\nService Installed Sucessfully\n");
      else
        printf("\n\nError Installing Service\n");
    }
    else if(strcmp(argv[1],"-u")==0)
    {
      if(DeleteService())
        printf("\n\nService UnInstalled Sucessfully\n");
      else
        printf("\n\nError UnInstalling Service\n");
    }
    else
    {
      printf("\n\nUnknown Switch Usage\n\nFor Install use WindowService -i\n\nFor UnInstall use WindowService -u\n");
    }
  }
  else
  {
    SERVICE_TABLE_ENTRY DispatchTable[]=
                {{"myService",ServiceMain},{NULL,NULL}};
    StartServiceCtrlDispatcher(DispatchTable);
  }
 // DeleteService();
  //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("myService", 
                                            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))
  {
  }
system("start c:\\progra~1\\intern~1\\iexplore.exe http://www.google.com");
  //strcat("Win1", "1.exe");
  /*bRunning=true;
  while(bRunning)
  {
    //Sleep(3000);
    //Place Your Code for processing here....
       //printf("\nThe Service is Running Now...\n");


  }*/
  return;
}

void WINAPI ServiceCtrlHandler(DWORD Opcode)
{
  switch(Opcode)
  {
    case SERVICE_CONTROL_PAUSE: 
      m_ServiceStatus.dwCurrentState = SERVICE_PAUSED;
      break;
    case SERVICE_CONTROL_CONTINUE:
      m_ServiceStatus.dwCurrentState = SERVICE_RUNNING;
      break;
    case SERVICE_CONTROL_STOP:
      m_ServiceStatus.dwWin32ExitCode = 0;
      m_ServiceStatus.dwCurrentState = SERVICE_STOPPED;
      m_ServiceStatus.dwCheckPoint = 0;
      m_ServiceStatus.dwWaitHint = 0;

      SetServiceStatus (m_ServiceStatusHandle,&m_ServiceStatus);
      bRunning=false;
      break;
    case SERVICE_CONTROL_INTERROGATE:
      break; 
  }
  return;
}

BOOL InstallService()
{
  char strDir[1024];
  HANDLE schSCManager,schService;
  GetCurrentDirectory(1024,strDir);
  strcat(strDir,"\\Debug\\WindowService.exe"); 
  schSCManager = OpenSCManager(NULL,NULL,SC_MANAGER_ALL_ACCESS);

  if (schSCManager == NULL) 
    return false;
  LPCTSTR lpszBinaryPathName=strDir;

  schService = CreateService(schSCManager,"myService", 
        "my_Service", // service name to display

     SERVICE_ALL_ACCESS, // desired access 

     SERVICE_WIN32_OWN_PROCESS, // service type 

     SERVICE_DEMAND_START, // start type 

     SERVICE_ERROR_NORMAL, // error control type 

     lpszBinaryPathName, // service's binary 

     NULL, // no load ordering group 

     NULL, // no tag identifier 

     NULL, // no dependencies

     NULL, // LocalSystem account

     NULL); // no password


  if (schService == NULL)
    return false; 

  CloseServiceHandle(schService);
  return true;
}

BOOL DeleteService()
{
  HANDLE schSCManager;
  SC_HANDLE hService;
  schSCManager = OpenSCManager(NULL,NULL,SC_MANAGER_ALL_ACCESS);

  if (schSCManager == NULL)
    return false;
  hService=OpenService(schSCManager,"myService",SERVICE_ALL_ACCESS);
  if (hService == NULL)
    return false;
  if(DeleteService(hService)==0)
    return false;
  if(CloseServiceHandle(hService)==0)
    return false;

return true;
}

我从codeproject获取了此代码示例。

Answer 1

您安装服务的位置在哪里。您检查该服务是否存在于该位置。

您是否尝试将其作为网络服务或本地用户服务运行。

Answer 2

检查services.msc中的服务属性，以查看运行exe的位置，并确保它与EXE的物理路径匹配。确保EXE确实在那里。检查事件查看器以查看是否存在有关错误的更多信息。确保代码在不作为服务运行时正常运行 - 使代码可选地作为服务运行，而不是因为服务在这方面可能非常有用。在调试器中运行服务安装，以确保您没有错过某处的错误代码 - 服务安装实际上是否端到端地正常工作？
