Windows Service Interactions - How To Access Event Log
Feb 6, 2011
I'm new to write windows services and I was searching around collecting necessery info and howtos. What I'm missing is the interaction between my webapp and the service. The servicecontroller sending messages to the service and gives me the main status of the service. Is there a way to get custom messages, set custom properties and get properties? If there are not, should I use a file for both the service and the web app where both can read and write on, like a settings file in xml or are there better methods? Is there a way to get the messages in the corresponding eventlog, how do I access them?
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.
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.
I have the following code, when I comment out the While loop, the service starts without any problems, but when I have that it wouldn't start, how can I go about doing the loop right after the service is started?
Protected Overrides Sub OnStart(ByVal args() As String) Dim serverSocket As New TcpListener(IPAddress.Any, 8000) Dim clientSocket As TcpClient
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').
I am trying to work on a service where I need to export a report into a folder under the service project and email it to the user. The delete the report when complete. The issue I am having is I need to know how to access a folder under the project. I know you can use System.AppDomain.CurrentDomain.BaseDirectory to get into the bin where the excuting file is but I want to get to a folder is this possible? If not is there a way of creating the folder under the bin directory and accessing it. I can manually create a folder under the bin but didnt really want to do that.
I've been developing in .NET (VB, C++, C#) for a number of years, but I am finally creating my first service application (in VB). I need to read/write to a file contained within a user's documents. As a service is not associated with a particular user, would a service have access to a user's documents? ...regardless if that user is signed on or not?
I have a very simple VB.net Windows Service written using VS.net 2008. The program after doing several other functions writes a log in one of the network folders. The code is as shown below: If I change the path from "Y:Activity_Log" to "C:Activity_Log" it is working like a charm.What is the problem if I use Y drive which is a valid one and I am able to access it from other VB.net desktop apps. Please help.
Dim strFile As String = "Y:Activity_Log" & DateTime.Today.ToString("dd-MMM-yyyy") & ".txt" Dim fs As FileStream = Nothing Dim activityfolder As String = "Y:Activity_Log" Dim di As System.IO.DirectoryInfo
I'm trying to do a simple select query from a MS access database from my service. Has anyone managed to do this in the past using their Jet eninge?
I had originally debugged and tested the code in a windows form and it worked fine. Once I moved the code into a windows service and installed it, it bombs out and doesn't generate any errors.
Thing is, I just found a .mdb file on the net so not entirely sure of the database version. I'm running office 2007 and read that if you used the .accdb version on a machine that didn't have access 2007 installed (which is going to be 99% likely), you had to install some drivers etc. in order for it to work. That is not an option unfortunately which is why I went with the old .mdb that could use Microsoft.Jet.OLEDB.4.0 without any drivers to be installed.
Do I need to import something into this project to get this to work? I've attached the code below. I've added a comment after the problematic line.
Dim con As New OleDb.OleDbConnection Dim dbProvider As String Dim dbSource As String
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.

I am newbie to vB .NET.I am developing an application for PDF files merge and split using vb .net (Visual studio 2008). Already i have included options for drag and drop and browse button to input the pdf files. Is there a way we can access global file select event and keyboard events to easy inputting the pdf files or any other files types??Example:if i use left mouse click along with control button the progrm will include the pdf file in the application form by getting the file path and file type information from windows explorer.
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.
I am trying to communicate with a Windows service on a remote machine on the network but i keep getting an exception saying the following: "System.InvalidOperationException: Cannot open Service Control Manager on computer 'machine001'. This operation might require other priviledges. ---> System.ComponentModel.Win32Exception: Access is denied.
Is it possible to have a dotnet windows service which monitor other services and upon stop of any service, the monitoring service would be able to start the stopped service.
In 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?
We 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?
I am using a windows service and tried to copy some file as below,System.IO.File.Copy("Z:abc.txt", "C:helloworld.txt")Note: Z: is a map drive from another host in 1 LAN (same LAN)I got error, "Could not find a part of the path 'Z:abc.txt'."But when I tried it at a simple application using windows application, it works with the same code as above.
Tried to write my first Windoes Service yesterday with a certain degree of success but I couldnt install it.Upon running teh Install programme in the command line I was presented with a 'Set Service Login' window with a User ID, Password and Confirm Password text box.I attempted to use my windows login credentials but the install failed and was rolled back.Im using a computer on a company network with Win2k?
I have created a Windows service in VS 2005 that monitors a folder for XML files, reads some data elements from the XML using XmlDocument, then copies the files to another location. I find that when I drop 2 or more XML files into the folder simultaneously, it processes them with no problems, but when I drop the same files into the folder one at a time, I will get an error on the second file: "The process cannot access the file <my file> because it is being used by another process." If I stop my service, restart it, and drop the second file into the folder again, it works the second time. I am confident that no other program is accessing this file at the same time as my service. My impression is that the processing of file # 1 is somehow not releasing all of the resources, leading to the processing of file # 2 mistakenly thinking that it can't access that second file.
Dim FileWatcher As New FileSystemWatcher() It points the watcher to my folder, sets up an event handler, then enables the watching: FileWatcher.Path = InputFolderPath
I've created a windows service and started a deployment project for it. I have the project installer class in the service project and I've added the "Standard output etc.." from the service project as custom actions for the Deployment Project. When I attempt to install it, I get the error "Specified service already exists", which shouldn't happen (even though the service does exist) because the installer should be removing the old service and installing the new one.
I've checked that the versions are different, and that the Product Code is also different, also RemovePreviousVersions is set to true. Can anyone tell me why it isn't uninstalling my old service when I update then install again? .S: MODS: DO NOT MARK MY POST AS ANSWERED, IT IS RUDE, YOU HAVE NO IDEA IF YOU'VE ANSWERED MY QUESTION!Sorry, it gets ignored in my signature.Mods
It is possible to create windows service using windows form control in vb.net. give me the url or links. The windows forms control such as, Timer control, list-box, notify-icon control etc.
I'm porting code that I wrote for use in a Windows Forms application to a Windows Service, but for some reason, the code that worked in the Windows Forms application is now throwing errors in the Service
I have developed a Windows Service in VB.Net (VS2010) which is running on Windows7. I am trying to get "MainWindowTitle" for processes thru their process object but it returns empty.
I'm writing a windows service (MacTimeFix.exe) to fix the Windows time on a Macintosh (it's like this: i live in Moscow (GMT+03:00), and Mac OS thinks that the system time is GMT+00:00 and adds 03:00 to it< and Windows thinks that system time is the local time).I need to execute my code when my VB app is closed. (it happens with the shutdown of Windows) The form is invisible (hidden), and the user mustn't click anything except windws shutdown button. It is a service. When i write a Form1_FormClosing sub, it works only on Alt+F4 or CloseButton and doesn't work when the app is stopped from Windows Task Manager or whatever also.I need a way to execute sub when app is closed with taskkill (without /force) or a way to execute a several app on Winshutdown.
Here is my code:
Public Class Form1 Dim SystemMary As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load SystemMary = Mid(TimeString, 1, 2)
