启动时出现 C++ 服务错误 : Could not Start the Service on Local Computer

Question

我已经使用 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，出现错误:无法在本地计算机上启动服务。错误2:系统找不到指定的文件。

这是我在服务入口点中定义的代码片段:

#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.dwControlsAccepted = SERVICE_ACCEPT_STOP;
  m_ServiceStatus.dwWin32ExitCode = 0;

  m_ServiceStatus.dwWaitHint = 0;

  m_ServiceStatusHandle = RegisterServiceCtrlHandler("myService", 
                                            ServiceCtrlHandler);

  {
    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)

  if (schService == NULL)

  return true;
}

BOOL DeleteService()
{

  SC_HANDLE hService;

  hService=OpenService(schSCManager,"myService",SERVICE_ALL_ACCESS);

    return false;
  if(DeleteService(hService)==0)
    return false;
  if(CloseServiceHandle(hService)==0)
    return false;

return true;
}

我从 codeproject 中获取了这段代码示例.

在 services.msc 中检查您的服务属性以查看您的 exe 应该从哪里运行，并确保这与 EXE 的物理路径相匹配。确保 EXE 确实存在。检查事件查看器以查看是否存在有关该错误的更多信息。确保代码在不作为服务运行时正常运行 - 让您的代码可选地作为服务运行而不是作为服务在这方面可能非常有帮助。在调试器中运行服务安装，以确保您没有在某处遗漏错误代码 - 服务安装是否真的端到端正常工作？
