About windows services and object lifetime

Hi all,

I want to host a remote object in a windows service. This remote object
fires events about service state. Clients connect and consume this events.
The service configures and marshal remote object in its constructor. When a
client application starts it connects remote object, registers events and
monitors service state. So far so good. When service stops, it fires stop
event via remote object and all clients know the service was stopped. Ok,
but the remote object is disposed now and clients have invalid object
references. If service starts again it creates new remote object and fires
start event via this new object. The result is some clients with invalid
object references and a service with a newborn remote object with no
connected clients.

So;
- I want an object which resides in a windows service and not disposed even
if the service is stopped. I should continue to use hosted remote object.

- When a windows service's constructor runs? On system startup? On first
start of a service? On every start of a service in the same session, or
only once per session? Is a service object disposed when that service stops
and recreated when it starts again?

- Is there any alternative to monitor service state other than periodically
checking it's state?

Thanks in advance

Is there a way to have a windows service instantiate a class that is a web service, which will then be accessible to clients via HTTP? Thanks, -Mike

Suppose there is a policy that all objects are statically declared. For example: static Car car(); Then, is there a reason to have a destructor defined for the class Car. It would seem that perhaps there would not be a need for a destructor because the object would never go out of scope due to the static storage.

I have been writing games and I also read about good programming techniques. I tend to create large objects that do lots of things. A good example I have is a unit object. The object controls and holds everything a unit in my game is supposed to do. What are some some cures for this kind of large object or are they OK because they represent one thing. If not what are better ways to design objects that behave the same way. Would it be...

Hi, I have 2 applications running, one Windows application project and the other windows services project. I want to call my Windows application in my windows services. I want to run them as seperate process. If my windows application starts running,only if it completes fully, then my windows services should continue its execution. My main process is Windows service.

I am reading the book "C++ Annotations", and here is a quote from the book: Namespaces can be defined without a name. Such a namespace is anonymous and it restricts the visibility of the defined entities to the source file in which the anonymous namespace is defined. Entities defined in the anonymous namespace are comparable to C’s static functions and variables. In C++ the static keyword can still be used, but its use is more

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
