"System.IO.Directory.Exists" In A Windows Service Using Windows 7?

Jan 23, 2012

I have created a windows service in VB in visual studio 2008.  The purpose of this service is to copy files from one network drive to the UNC path for a sharepoint file location.  It works properly on a Windows XP machine, however when I installed it on Windows 7, I am now getting Access Denied error messages.  In troubleshooting, I tried to simplify things to see if I can see the directory that I'm trying to write to, and the System.IO.Directory.Exists is returning false.  I am able to see other netowrk shared drives, just not this particular one, and it appears to only be an issue from my Windows 7 machine, as I can do this with a Windows XP box. 

I have also tested this code in a Windows forms application and it will work as expected.  It appears only when I move to the service. 


Install Windows Service Using A ProjectInstaller And A Deployment Project ("Specified Service Already Exists")

Mar 10, 2009

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

Windows Service To Import Data From CSV Files Dropped Into A Directory?

Jul 26, 2011

I am writing a Windows service to import data from CSV files dropped into a directory. One of the steps is to load an XML file with validation rules which I load into a List(Of T). It will pull the data, and then I have it pass the list to a class that monitors the folder and processes the files. After that I clear the list and read in the next file configuration. Now I have noticed that the validation rules aren't matching up and it seems that the list is being passed as a reference type even though the signature is of a value type.Is there anything I can do to get around this?


So here when I pass it, at first it will have 3 validation rules in the new ImportService class I created, but when I call fields.Clear(), it wipes out the class member of the ImportService class.

VS 2008 - Use An Icon In The System Tray To Let Interact With A Windows Service

Sep 24, 2009

I've seen loads of programs that use an icon in the system tray to let you interact with a windows service that is running on your machine but I am curious as to how this works. As I understand it, unless a service marks itself as 'interactive' then it has no way to communicate with the user's desktop and doing so is discouraged by MS (and even causes an alternate desktop to appear temporarily in Server 2008 in some cases). So I want to try and avoid doing this but I cant think how else I would do it, and even if I marked my service as interactive I'm not too sure how I could actually get it to show a notification icon in the system tray.

I assume I would have to use Windows APIs, unless just using the windows forms NotifyIcon class would work. I considered just having the system tray icon in a totally separate application that just communicates with the service via named pipes or TCP etc but I'm pretty sure this isnt how other programs do it because with most of them if you just kill the process that the service is running in then the icon disappears so it must actually be directly running from the service.

VS 2010 : Change Application From Windows Form To System Service?

May 3, 2012

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.

Windows Service Unable To Access A File In Program In Windows 2003 Server

Writing A Windows Service (MacTimeFix.exe) To Fix The Windows Time On A Macintosh?

Jan 31, 2009

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)

.net - WCF Service Hosted In A Managed Windows Service Connect Using A WCF Service Application

Jul 14, 2011

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

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.

C# - Gradually Increase System Volume On Windows Mobile / Windows CE 6.0

Jun 19, 2012

I'm attempting to use waveOutSetVolume from coredll.dll to gradually increase the audio volume from silent (or near silent) to maximum.

Most of the code examples I'm finding show some predefined set points for Off, Low, Normal, Medium, High, and Very High like this:

Public Enum Volumes As Integer
OFF = 0
LOW = 858993459


OK, and here's some API documentation which doesn't make a lot of sense to me in this particular context. What is low-order word and high-order word and how can they both exist in a single value?

· dwVolume New volume setting. The low-order word contains the left-channel volume setting, and the high-order word contains the right-channel setting. A value of 0xFFFF represents full volume, and a value of 0x0000 is silence. If a device does not support both left and right volume control, the low-order word of dwVolume specifies the volume level, and the high-order word is ignored.

System.file.io In Windows App Running On Windows 7?

Jan 25, 2010

Just placed out first Windows 7 PC in to a production environment and noticed that system.file.io gives errors about file not existing when using mapped drives to a network server. I can access the file through Explorer on the PC.  When I chnaged the path to UNC using the IP and drive name instead of the mapped drive letter all works fine.  Strange thing is for a few days during the testing period the application ran on Win 7 using the mapped drives in the file.io path.  Not sure why it stopped working or how it worked in the first place.  Question is on Windows 7 it seems like it doesn't like mapped drives in system.file namespace. Is tis true or are there more steps I need to do in addition to this  This works as is, but when I change \172....vol1 to r: it bails, hence the thinking Win 7 is stopping the access to mapped drives.

Windows Service: Multiple Instances Of The Same Service Class?

May 3, 2011

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?
