I have a service that receives commands over the network and interacts with the database. At the time that I add a transaction I would like to print some sort of receipt ticket out to an epson tmt88iv. I would like the service to do this rather than have to maintain the printer on several tablets....Is this possible?
View 2 RepliesSince 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..

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.
I've been google'ing around trying to look for examples of Windows Services using socket connections but everything has been C# or C++... I know this isn't 100% secure, but I want to do it as a practice: I want to create a Windows Service that listens on a specific port. When data is received I want to parse it as a command. For example, say I send "ring" to the IP/Port running the service it will play ring.wav.

I created new windows service with timer inside it for scheduler purpose and it can run successfully but it can't run other application (ex: notepad) when the timer elapsed. I can see the process running in Task Manager but the notepad windows is not open. I used this code in timer_elapsed event.
AppLauncher oAppLauncher = new AppLauncher(@"C:WindowsRegedit.exe");
new Thread(new ThreadStart(oAppLauncher.StartProcess)).Start();

In Visual Studio when I try to start a windows service project it tells me I cant because I have to use "NET Start" and so forth. I remember in VS 2003 that when I pressed play it started the service and stop stopped it. Is there any way that when I press play or start for that windows service project I can have this same functionality. What I currently do is install them using installutil and I put a pre-processor command with System.Diagnostics.Debug.Launch() when I have a compilation variable defined and when I use the service manager it shows me the window to select the debugger. Still this method is somewhat cumbersome.
View 1 RepliesI have had some success making a windows service but I can�t seem to fix a simple issue
I can get the service to run through my code once, but I can�t get it to loop, well I can but then the service will not start correctly and just times out while the code is running.
How can I get the service to start and then loop, at the moment it just says starting service and the code is looping but the service wont start! Windows times it out after a few mins.

I have a Windows Service that is behaving strangely on Windows 2003 systems (works fine on XP, Win7). If the service is started manually within the OS, then everything is fine. However, if the system is rebooted (with the service set to Automatic startup), then an "At least one service or driver failed during system startup" dialog is generated once the boot completes. If I check the event log, there is an event 7022 with the following text:

View 1 RepliesI have a windows service written in .net framework 2.0. This service installs and runs perfectly fine on both XP and windows server 2003.We have a new 2008 box that we are migrating over to, so need to get this windows service up and running.When i try to 'start' the windows service on the 2008 machine, i get "Windows could not start the <service> service on local computer. Error 1053: The service did not respond to the start or control request in a timely fashion."I have searched everywhere looking for an answer, and all I could find was a fix attributed to .net framework 1.1 for this same error. That; however, is not applicable here, as the service was written in 2.0.

Basically I have created a windows service using VB 2008 where I am trying to capture screenshots periodically. The timer is working fine and I have tested this. The purpose of the service is to monitor the desktop over night when the user is logged off, by capturing screenshots and saving them to file. This is so admin can be alarmed about security breaches etc.

I've created a Windows Service and installed it via InstallUtil so I can test it out.The installation goes seamlessly, but it will not start from some reason. When I attempt to start it, I get an "Access Denied" error and that's it.
I haven't been able to find any information via the normal channels.I first thought to give the service admin rights, but that didn't work either.
I've written a windows service in VB.NET 2.0 and the service needs to know a few file paths and other settings when it starts in order to be able to do what its supposed to do. These are settings that users of my service need to be able to configure themselves so I cant hard code them in.At the moment I just have the service look for a file named Config.INI in the same directory that it is being run from and if this file exists it attempts to read the settings in from there... this works perfectly, but it just feels a bit clunky and old. If it was a normal windows app I would store the settings in an XML file in the user's application data folder or something but as this is a Service then thats not possible as it is not run by any one user (well technically it is, the Local System account). I then thought about using the registry but I seem to recall people saying that you should avoid storing settings in the registry if you can really, especially with the new security in Vista and Server 2008.
View 6 RepliesI am working on a VS .NET 2008 windows service for 2003, however it doesn�t appear to work correctly.I am basically reading a file from a networked computer and trying to display it�s content, the code is as follows:

Protected Overrides Sub OnStart(ByVal args() As String)

Now, everytime I run this service it logs the events inside the "GetMachineVol" function, but I never get to the ""Ticked at "" event log from the "main" sub, pretty much as if the service stopped working after trying to assign the value returned from "GetMachineVol" to the string "MachineVolBSFull". I tried using this code on a windows form and everything works fine, and since debugging a service is quite beyond my skills, I really do not know what could be wrong.

View 2 RepliesI am working on a backup utility for use with the mysql db. Because I need the actual backup to run regardless of if a user is logged on or not, I created the backup engine in a windows service.
Basically the backup engine checks to see if a backup job is scheduled to be run and if it is, it kicks off a mysqldump to do the backup. For sake of performance I am saving all backup jobs to the local c: drive then doing a file copy to the user defined destination.
Everything works fine except for the file copy. If the user selects a local resource to the computer it works fine. However, if a network drive is selected, I get an error that it cannot find the path.
I started thinking about it and believe this is expected since the backup engine is probably oblivious to whatever mapped drives that particular user has, i.e. the mapping process is done when someone logs in and my app is running at a lower level.
I started doing some research on this problem and found that some people are saying that windows services are oblivious of networks all together. This seemed a little odd to me so I thought I would bring the issue here.
Is a windows service truely unaware of network activity? How can I change the program to move the completed backups over to a network drive?
Ok for some reason I am having multiple problems with this code. The first issue is that one of the lines of code is seemingly ignored. Another issue is that some of the events are firing many times when they are only supposed to fire once. I have attached my code.

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?
I want to create a Windows Service using VB.Net, but in VS2008 Standard, you don't seem to get the "Windows Service" template I've used before.
What's the best way of creating such a service, without resorting to using the C++ template?
