Windows Service Access Folder Under Project?
May 17, 2011
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.

Ok I know this question has been asked to death but I still have not seen a good answer. I have created an application in VS2010 using VB.NET. In my application I have an error log that is an XML file located in the Public gstLocalErrorLogLocation As String = Application.StartupPath & "ErrorLog"that gets written to in the event of an error so I can trouble shoot application easier. My application also downloads files from our FTP site and puts the files in Public gstLocalDownloadLocation As String = Application.StartupPath & "download"So I have files that get read and written to as well and created and deleted all in the Application.StartupPath which is either "c:Program Files(Application Directory)(Some Directory)(Some File)" or "c:Program Files (x86)(Application Directory)(Some Directory)(Some File)" depending on 32bit or 64bit Windows 7.
After creating the setup I install it on my test machine that have both Windows 7 32bit and 64bit.Everything in the application works great till I have to write to, delete or creat a file in those directories above. I know it is an access issue and the UAC. This will get installed on numerous systems so the options I have seen to change file or folder permission on the computers manually is not an option.What has to happen is after I install the application it just works like when you install it on XP. Some post have suggested that you us a user with administrator privilages or group which is all fine and dandy but the user I have used to test the application has all of that.
So what I am asking is how do you create an application with VS2010 in VB.NET that after creating a setup package and installing on Windows 7 will just work with out "Access to the path c:Program Files(Application Directory)(Some Directory)(Some File) is denied." If I have to install this on 100 Windows 7 computers it has to be a concreate no manually doing anything just install and work like when we installed on XP.

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

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 developed an application in VB.Net 2005 Express. This app was then transformed into a windows service using a template I found on this forum. I am able to install the service using InstallUtil.exe and I am very happy, BUT the powers that be me are asking for a more eligant method of installing / upgrading the service.
All of my reading suggests I need to upgrade to VS 2008 Enterprise to achieve this goal. Before I lash out and reach for my credit card, can someone confirm the minimum requirement to achieve a pretty service installation.

I'm currently starting work on my first windows service and I've encountered what I find to be a strange error. For some reason the compiler is telling me that a whole bunch of typical classes (such as Image, Bitmap, Graphics, etc) do not exist. For example, these simple lines of code, which work perfectly in a normal project, return a bunch of errors:
Bitmap b = new Bitmap(destWidth, destHeight); //Error 13 The type or namespace name 'Bitmap' could not be found (are you missing a using directive or an assembly reference?)
Graphics g = Graphics.FromImage((Image)b); //Error 17 The type or namespace name 'Image' could not be found (are you missing a using directive or an assembly reference?)

Now that I've got this service that runs really great on my 32-bit development machine when I use InstallUtil.exe to install it, I'm ready to take it to the next level and generate something that I can use to install it on my 64-bit production server. I've never done this before, so I'm looking for detailed, step-by-step instructions on how to "publish" this Windows Service that I've written, or make it such that I can take some kind of file (or set of files) and install my service on another machine. I'm looking for a way to do this using Visual Studio 2010. I think the processes are different than in previous versions of Visual Studio.

I have a web service that I'd like to include as a project reference inside a windows forms application. (The application will be running on non-networked hardware.) I could simply copy the *.vb files I need into my forms project, but I'd rather not fork the code base.It wasn't hard to include the ASP project in the windows forms solution. However, I can't figure out how to reference it in my forms code.

I've been busy with work and other bits and bobs and not really had much time for programming... but anyway, I have just written a fairly simple windows service in VB.NET and although I can install it on my PCs/servers using the command line InstallUtil.exe component, this isnt ideal for other people that may need to install it without my assistance.
So basically I just need to know how to get a normal Setup and Deployment VS project to install this service itself... I thought it would be as simple as selecting the service assembly to include in the deployment project and building it, but unfortunately that seems to do naff all. Do I need to use a 'Custom Action' in the setup project (and if so, how/what do I do?)

I am creating a windows service in VS2010, and in order to store a user's input during installation I've been told to write it to a file called app.config.However i cannot find this app.config file? Does it create one in a windows service project? or just in a WCF windows service project?

I have a simple windows Service developed in VS.net 2008 and VB.net. When I install the service using Installutil.exe from the command prompt it is working like a charm.
When I try to add a setup project and set the output and build and install it though it says successfully installed, it is not showing up in the services.
The event log shows that it is successfully installed. I just did check the registry, it did place the assemblies in HKEY_CURRENT_USERSoftwareMicrosoftinstallerassemblies.
But I don't understand why it is not showing up in the services listing. I refreshed and restarted.

I need to install a windows service via an .msi for many tablets which is nooooo problem. The problem is, the tablets currently have the service running which was installed by installutil. So when my installer runs, regardless of Remove Previous Version is true, it stops stating the service already exists and to uninstall it from Add/Remove Programs.So I wrote a console app which preceeds the primary output as follows:
Sub Main()
Try
Dim filename As String = "C:Program FilesRSCProjectServiceSetupRSCProjectService.exe"

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'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 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

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've been struggling with this problem in VB.net for a while: whenever I try to access the My Documents, My video's or simular in Windows 7, I get an access denied error. The program that uses this code is a file-backup application, so it's important it can access everything. The app has admin rights, using this line:requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
To confirm, I also get a nice UAC popup when starting.The app accesses the files twice. Once to calculate the file size, and once to actually copy the files. Here is the file-size calculation code (that I found online:) Function GetFolderSize(ByVal DirPath As String, ByVal includeSubFolders As Boolean) As Long

I have programs written in VB2005 accessing mdb database in server. When the server run XP, it was never a problem (at the time, the folder was shared to all). There is a new rule in the company and we have Win 2003 server, and my mdb file must be stored in a folder in the server that the administrator (not I) have installed password. And clients are supposed to access it as user only. I can ask password as administrator, but the users of my program must not have the administrator password (which I can included in my program if necessary). How can I modify my program so that it can access the database? I assume I must modify my connection string, but I do not know how. I am currently using this:
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source= C:Integrity ERPPBF.mdb;Jet OLEDB:Database Password=ABC"

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.
