The MFC client is probably running in the security context different from
the service. Therefore, you have to pay particular attention to the access
rights of the event's security descriptor
see
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/synchronization_object_security_and_access_rights.asp
(watch for line breaks)
You might want to set the first parameter of CreateEvent explicitly, as in:
CDacl dacl;
dacl.AddAllowedAce (Sids::World (), GENERIC_READ | EVENT_MODIFY_STATE |
SYNCHRONIZE);
CSecurityDesc sd;
sd.SetDacl (dacl);
CSecurityAttributes sa;
sa.Set (sd);
...CreateEvent (sa, ...)
