A simple example of starting and stopping a service in windows using C++

Hey all,

Here is a simple example of starting and stopping a service in C++. Just pass the service name as a parameter and the service will switch states. If stopped, it will start. If started, it will stop.

// StartStopService.cpp : Defines the entry point for the console application.
//

#include “stdafx.h”
#include
#include

int _tmain(int argc, _TCHAR* argv[])
{
SC_HANDLE serviceDbHandle = OpenSCManager(NULL,NULL,SC_MANAGER_ALL_ACCESS);
SC_HANDLE serviceHandle = OpenService(serviceDbHandle, argv[1], SC_MANAGER_ALL_ACCESS);

SERVICE_STATUS_PROCESS status;
DWORD bytesNeeded;
QueryServiceStatusEx(serviceHandle, SC_STATUS_PROCESS_INFO,(LPBYTE) &status,sizeof(SERVICE_STATUS_PROCESS), &bytesNeeded);

if (status.dwCurrentState == SERVICE_RUNNING)
{// Stop it
BOOL b = ControlService(serviceHandle, SERVICE_CONTROL_STOP, (LPSERVICE_STATUS) &status);
if (b)
{
std::cout << "Service stopped." << std::endl; } else { std::cout << "Service failed to stop." << std::endl; } } else {// Start it BOOL b = StartService(serviceHandle, NULL, NULL); if (b) { std::cout << "Service started." << std::endl; } else { std::cout << "Service failed to start." << std::endl; } }CloseServiceHandle(serviceHandle); CloseServiceHandle(serviceDbHandle);return 0; } [/sourcecode]
