I have created a Windows service that acts as a server for my app on a mobile platform. Whenever a user sends a message to my app I process it . Now i Would like to send the message that the user sent to my server to an application. Something like SendMessage would be absolutely perfect But how do you fit a whole class into the Wparam and Lparam 's of a window message ?

I have a .net Windows Service developed in VB.net. I have a settings file in the root directory called Connections.XML and I am setting the basedirectory [code]...
When I schedule the service this is working absolutely fine in my Windows XP machine. But when I installed the same service in our development server (Windows 2003 64 bit Server) for some reason it is not able to locate this file.

View 2 RepliesI created a new Windows Service and a stand alone set up program for it. To the solution I added a set up program project and included both programs as outlined in [url]... However, when I run the Setup program, I do not see the my new service in the services window after the set up program completes. Is there additional work that needs to be done to have the program install the windows service correctly or do I need to include the [url]... program and a batch file to get it installed?

View 1 Repliesi have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.
What i want to happen is for the dictionary keys and items to be overwritten each time it is executed, as the data needs to be up to date.

View 1 RepliesI upgraded to VB2010 from VB2008 early this year and have been working on a Windows Service which I am now debugging. When I was using VB2008 in Windows XP SP3 I would put a Stop statement in the code and when execution got to it a dialog would open asking if I wanted to debug it using a development environment listed in a provided list. The list contained the VB2008 VS IDE which I selected which would in turn transfer me to the IDE in debug mode. I was very happy with this setup.
Now I am using VB2010 with Windows 7 and when the execution reaches the Stop statement the service just stops. It no longer offers the choice and ability to "jump" into the development environment via the dialog that I mentioned.[code]...

We have constructed a windows service unde W2003 Server in vb.net 2010 to process certain database transactions. It should work 24/7 o the server. However, after 3/4 days it blocks the windows server operation since the memory usage is ever-increasing. After many revisions, we decided to place under "comments" all operational code, including all transactions to the SQl Server database and left just a kind of shell service that is doing no real work. Still, under these circumstances, the memory usage goes on increasing. Any idea how to prevent this from happening?
View 7 RepliesI wrote a custom windows service (VB .Net) to run some processing on data files in the background of one of our servers. The service basically finds the next file to process, breaks it apart and makes a PDF or two - nothing super complicated. It utilizes a timer, if a file is not found, it waits a bit and checks again (repeat indefinitely). The service has run for a week or two with no issues/pausing/stopping. I have plenty of error handling for this and I have not been able to break it... until today.

I have built a Dll and a Windows Service in vs2010. Both are targeting the .net 3.5 framework, but when I install it on the server it installs fine, but for some reason it targets the 2.0 framework and any time the methods fire that are using linq it crashes out with a clr20r3 error system.nullreferenceexception. Not really sure why it's not targeting .net 3.5.
View 10 RepliesI have a windows desktop application that I'm converting part of it to a windows service application. The win service pulls data out of one database and passes it to a central location via web services. I've got the windows service working, however I'm unsure how to add auto update abilities to it.
The windows service itself is basically an empty shell that fires off the data pulling, which resides in a dll that installs with the service. My original idea was to have the windows service do a version check and if needed download the new dll and overwrite the old one. The problem is the copy can't happen if the service is running (or paused). Herein lies the problem. If I have the service stop itself then of course it's stopped so no more code execution. The other problem would be how to restart it.
I'm trying to create something that is hands/worry free for my clients that way when I change/update the data pulling win service application they don't have to mess with it. I'm up to 300 clients now and I really need a solution that doesn't involve any user interaction.
EDIT: After more digging it's looking like this is a near impossible task. Another option would be to have a second service, one that just looks for updates and that second service can stop the first, update it, then restart it.

I have tested my code in a windows form project and it works great. so now I want it to run as a service.The problem i have is referring to "name" in my configuration string which is in app.config.

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.
Since the coming of Windows7 at our office we have sometimes the issue that the print spool is crashing.Users don't have admin rights to restart the service so that leaves them only at restarting their computer as solution.Which costs alot of time... As we cannot find a final solution to this problem I've begin to write a small tool so they can restart it..I've only hard code a local admin account in the source for this operate for them..

I have used VB before but it's been a long time. I looked at some of the settings and it looks like it has a SerialPort com component I can use. Will it suffice for this project?Might be a simple question, but just want some tips from experienced developers.
When you create a Windows Service, you create a list of the services you want to start. The default is this:
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service}
Can you have multiple instances of the same Service class (that bind to different addresses or ports), like this?
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service("Option1"), New Service("Option2")}
Or will that cause problems? Should we use two different classes instead?
