Under which I am creating a event "test". I want to use the same event object to be set/reset by my application. But I do not seem to get the Handle of the event object through my app. But can see the Event being listed in the BaseNamed objects. I think I need to do something with the security Attribute of the create Event. I am creating this event in my http://stackoverflow.com/questions/18890783/open-an-event-object-created-by-my-service-from-my-application service CreateEvent(NULL, TRUE, FALSE, TEXT("Test")) and using OpenEvent in my application. OpenEvent( EVENT_ALL_ACCESS, TRUE, TEXT("Test")) Please suggest what changes I would need to make, for my app to get the handle. update After Replacing TEXT("Test") with TEXT("Global\\Test"). Still I didn't get the Event object handle. Yes, now at least its recognizing the existence of the event object with the Error return(Access Denied). It was getting a Error return (the system cannot find the file specified) earlier. As I said, I think there is some security aspect here. This is what I found out: As the session creates the Event in Session 0. It cannot be inherited by my application which is being created in Session 1. For that while creating the Event object, I need to specify the security attribute structure with a proper Security Dispatcher to do so. Could somebody tell me how to do so? windows winapi service share|improve this question edited Sep 19 '13 at 12:29 asked Sep 19 '13 at 9:19 WIN_SOM_LIV 657 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted Try this: PSECURITY_DESCRIPTOR psd = (PSECURITY_DESCRIPTOR) LocalAlloc(LPTR, SECURITY_DESCRIPTOR_MIN_LENGTH); InitializeSecurityDescriptor(psd, SECURITY_DESCRIPTOR_REVISION); SetSecurityDescriptorDacl(psd, TRUE, NULL, FALSE); SECURITY_ATTRIBUTES sa = {0}; sa.nLength = sizeof(sa); sa.lpSecurityDescriptor = psd; sa.bInheritHandle = FALSE; HANDLE hEvent = CreateEvent(&sa, TRUE, FALSE, TEXT("Global\\Test")); LocalFree(psd); HANDL
