We have a VB windows service running on LocalSystem Account. This windows service uses Kodak Imaging Components for converting PNG to TIFF files . Service is throwing "Out of Memory Error" for the code ImgEdit.Display . I just converted this service to a normal console vb program .This program runs fine without any error .
View 1 RepliesWe 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?

I've installed a vb.net windows service on a Windows 2008 machine, that is attempting to connect to SQL 2005. The service starts succesfully, but can't see the database. The event log has the following entry. The description for Event ID 0 from source SU4.ESMR.DAL.Job.FillPriorityJobByType(oJobDS, TypeID: 3 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

I new to .net My project involves developing a windows service application using VB .NET. I have installed the service successfuly on the first attempt using the installutil provided by the frame work.When i uninstalled the application the it gave me the following result.
System.ComponentModel.Win32Exception: The specified service does not exist as an installed serviceAn exception occurred while uninstalling. This exception will be ignored and the uninstall will continue. However, the application might not be fully uninstalled after the uninstall is complete.
The uninstall has completed.
When i tried to install the app again it gave me the following error
An exception occurred during the Install phase.System.ComponentModel.Win32Exception: The specified service already exists
I removed the application from the list of application event log entries in the registry(HKEYLOCAL_MACHINESYSTEMCurrentControlSetServicesEventLogApplication) ant tried installing the app agin it installed successfully. Why is uninstalling the service not removing the entry from the registry.
I've developed a windows service that connects to a database and executes a Stored Procedure when running in debug mode I get the following message: "ContextSwitchDeadlock was detectedMessage: The CLR has been unable to transition from COM context 0x1ffc20 to COM context 0x1ffd90 for 60 seconds. The thread that owns the destinationcontext/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations."

i 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.

View 4 RepliesIn the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?
View 1 RepliesWhen 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?

I have a windows service I created that checks for data to post to an off site webservice over SSL. The service checks every 10 seconds for data to send, if there is data it opens a connection to the remote webservice, and closes the connection after 120 seconds (still checking for data to send during this time). The service works fine if a user is RDP'd into the server, but as soon as no one is logged on and the service attempts to push data, I receive the following error:"The underlying connection was closed: An unexpected error occurred on a send."I have tried running the service as a local service, network service, under my login, and under a service account, but nothing seems to work.

I get the error mentioned when printing to a network printer.The error does not occur when run under XP/Win2003, in a WinForm app or when a local printer is used.The error does only occur when run as a Windows Service under Vista/Win7/Win2008 and printing to a network printer.The Windows service runs under a network user that has access to the network printer. Before I print I check if the printername (including network path) is ok by looping through the available printers.
View 1 RepliesWe have a server with multiple services written in .Net 1.1 and 3.5 running on a Win 2003 server. Everything runs fine, but when we stop a certain service, an unrelated service stops. I have checked and neither has any dependencies. The service we stop is in 3.5, and the unrelated service that incorrectly stops is in 1.1. We get no error messages, nor event log errors, so we are baffled.Does anyone have an idea as to what may be causing this?

View 6 RepliesThis is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.
This code was put together for a one time run. It's purpose is to count all the pages in a group of images. After about 6000 of 1,250,000 images in ##X it throws an "out of memory" error. Besides it being thrown together for a one time run does anybody see anything obvious that could be causing the error?
