Show User Form On A System Service Event Via IPC Remoting?

Jul 7, 2009

I am struggling with this issue for serveral days now.My application needs to work like wsus (windows updates) does. On a certain event triggered by a windows service working under SYSTEM account it needs to show a (second) form under the user context.The IPC Remoting works fine so I think my issue is in the threading.When I use form2.Show() form2 appears but the form freezes.When I use form2.ShowDialog() the form appears but I cannot get the focus on it.

Service running under system account (in this example a simple console application)

Code:Imports ClassLibrary1Module Serv
Sub Main() Dim SDSIPC As Semaphore = CType(Activator.GetObject (GetType(ClientFromServer), "ipc://Client/SreeniRemoteObj"), Semaphore)
SDSIPC.DoSomething()

Build Correct Way Of N-tier Apps Without Service And Remoting?

Jul 4, 2009

How to build the n'tier application. I have read some book tell about this, like "Building Client/Server Applications With VB.NET" by Jeff Levinson, beth massi video tutorial "building simple n-tier applications", and other else.

In my practice, i create 3 projects to handle each layer progress. That are DAL (Data Access Layer), BLL(Business Logic Layer) and UIL (User Interface Layer).

My problem is i don't want to use web service like beth massi do, and i don't want to use remote object like Jeff L do. So i decide to create it by my rules. Here above something that i do.

In DAL Section, I put all datasource like Beth Massi do over here. I also create a manager class like massi do to handle datasource over here. Also in this class, i create the UML structure of this datasource.

Windows Service Detecting User Log Off Event?

Aug 15, 2011

Recently while I was playing with VS 2008(VB), I have created an application for folder sync purpose... which is working fine. Then, I have created a windows service that does the same thing and it is also working fine(from application perspective). But, I have been trying to add some additional functionality to that new service. It keeps on running as long as System is ON.

But I would like to change the functionality to... as soon as user logs off Service should STOP, and should START when user logs into that PC. I tried to find some useful info online(related to my task) and all I could come up with was to add OnSessionChange(...) method to the service. But for some reason it is not working out for me(when I've logged off or other system events such as 'system lock').

VS 2010 : Change Application From Windows Form To System Service?

May 3, 2012

one of the apps that I wrote a couple months ago is getting to be rolled out to my production floor; one issue tho - It works great as a standard executable (you double-click, it starts and waits for data), however, I cannot get it to start as a system service.

I've already done a little bit of research for how to create a system service, but most of the information that I've come across is point to VC# or Visual Studio 2010 - I'm not finding much for VB 2010. Additionally, I'm only using VB 2010 Express and I'm pretty sure that I don't have the Windows Service application template's on my PC.

My application does have a "UI", but there isn't any user interaction; it starts and just sits minimized in the system tray polling a directory for the existence of a file - i.e. the windows form is not required.

VS 2008 Working With A Service - User Form?

Jun 25, 2009

I am jsut adding bits on to a Windows Service we are making here at our company, its an Asset Management tools with a few built in extras. It runs as a service on everyones machines but we can also do things like request a reboot etc through it.At the moment when We send a Reboot/shutdown etc command to it the Service on the machines calls 'C:WindowsSystem32Shutdown.exe' with the appropiate switches. This displays the windows shutdown warning to the users but nothing they can do about it.

What I was wondering if I create a seperate exe (or even better built into the service but I am not sure if this is possible) instead of the Service Calling 'shutdown.exe' it calls this form up to the user which states that we have requested a reboot etc but there is a 'Cancel' option. The Cancel can just end the form/program and nothing more, if the timeout that we specify is reached then that form/program then calls shutdown exe for an instant shutdown.

I know that the Service runs in a different user Space and we have no telling of who is logged on to that machine so I will need a way to just launch the form to any logged on users. Doesn't matter to much if there is no one logged onto the machine but if it does display this form while noone is logged on that is not a big deal.

VS 2008 Windows Service Event Log In The OnStart Event

Aug 26, 2010

I have created a simple framework for a Windows service in VB.NET Express 2008. It enables a timer which then writes to the event log every 6 seconds until the service is stopped. This works fine. I adapted that framework into something further. It is using Windows sockets. Well, I haven't finished that part yet and I just want it to write to the event log successfully but I can't even get it to do that now. I am trying to write an event in the OnStart event. The service is being started successfully, according to the standard event log, but my custom events are not getting there. I don't understand why as I am using the same code for that as I was before.

Get Information About A Processes When An System Process Event Is Raised An Event

May 17, 2012

I am making a function of an application that when a function is called the application will close all processes that are owned by the user and were started after a specific point. My thoughts on this would be to trigger an event in my application every time a process is started and ended, and only if the processes is owned by the user, the event should get information (e.g. the process ID, name, etc) about that process and add or remove that information to/from an array depending on if the process starts or ends. Then when a function is called end all the processes in that array.
