Automatically Start Windows Service on Startup [modified]

[narayanagvs]

Hi, I would like to create a windows service which automatically starts on startup and calls my function.I dont want to use .NET support for this. Using ATL I have taken a windows service project.I build it and registered the service using "/Service" which is then shown in Services with "Manual Startup type". I would want this to be automatic. How should I go about it? For this while creating the service we need to specify "SERVICE_AUTO_START" flag. But this service creation is automatically done by the base class CAtlServiceModuleT.

SC_HANDLE hService = ::CreateService(
hSCM, m_szServiceName, m_szServiceName,
SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS,
SERVICE_DEMAND_START, SERVICE_ERROR_NORMAL,
szFilePath, NULL, NULL, _T("RPCSS\0"), NULL, NULL);

Now How should I go about overriding the base class functions. I know I need to make use of _tWinMain() and override but Iam not sure of the approach. Any suggestions or relevant links would be helpful Thanks Satya

Today is a gift, that's why it is called the present.

Override the base implementation via copying the code in your project and change it. Or you can try to change the startup type of the service yourself (somehow).:confused:

After the Install method of CAtlServiceModuleT is called, you could use OpenService to get a handle on the service and then ChangeServiceConfig to alter the service's start type to SERVICE_AUTO_START? Looking in the code, you could override RegisterAppId to do that, as RegisterAppId calls the Install method - you can't just override Install, because it's not virtual - RegisterAppId is the closest method called using a correctly typed object pointer (look for pT->RegisterAppId in AtlBase.h). Something like the code below should work? HRESULT RegisterAppId(bool bService = false) throw() { HRESULT hBaseRes = CAtlServiceModuleT< CbModule, IDS_SERVICENAME >::RegisterAppId(bService); if (SUCCEEDED(hBaseRes) && bService) { HRESULT hRes = E_FAIL; SC_HANDLE hSCM = ::OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS); if (hSCM != NULL) { SC_HANDLE hService = ::OpenService(hSCM, m_szServiceName, SERVICE_CHANGE_CONFIG); if (hService != NULL) { if (::ChangeServiceConfig(hService, SERVICE_NO_CHANGE, SERVICE_AUTO_START, SERVICE_NO_CHANGE, NULL, NULL, NULL, NULL, NULL, NULL, NULL)) { hRes = hBaseRes; } ::CloseServiceHandle(hService); } ::CloseServiceHandle(hSCM); } hBaseRes = hRes; } return hBaseRes; }
