File I / O And Registry - Interact With Windows Services
Apr 28, 2010
I'm trying to write an application in VB 2010 that will allow me to send out stop and start commands for two services. I can get this to work in a batch file but not in VB, using either NET STOP and NET START and also using SC.exe Stop and SC.exe Start. But I don't seem to get anywhere if I try to use this in VB. So far this is what I have written, using the Print Spooler service as an example. The two services I actually want to stop and restart are the Server and Client services for efpos terminals that are attached to the computers. The service fails from time to time and I want to provide a solution for our users that is quick and easy for them to use, and most importantly doesn't require them to restart the computer, while they have a line up of people waiting to pay.
Code:
Private Sub SpoolerStop()
' Stops the spooler service
Dim StopSpooler = "C:windowssystem32sc.exe stop spooler"
End Sub
No matter what search terms I try in Google I get very little on using VB to interact with Windows Services.

I dont know that this is the right thread to ask doubt about windows service.But it is very urgent. I am helpless. So i am coming to this forum. I am using windows services. I have one exe file(MFC application). Using windows service i am calling this exe file like
System.Diagnostic.Process.Start(Path); When services run the exe is opened but the callback function is not running. I give a AfxMessagebox inside the exe file. In local it is executed.But when call from services it is not fired. The function is not executed.

I'm Writing a program for my VET IT class at school, so other IT students dont ruin computers we have set up. the program is working great, with only one problem. the program carries out its task, even during debugging (Although it shows an error.) the problem is with windows. in order to stop users from pressing the windows key, the program turns of windows explorer when run, and turns it back off afterwards. before doing this, windows asks for permission. does anyone know how to use visual basic to automatically interact with this messagebox?i have uploaded a video showing my program in action and the problem. (Will Comment With the video when it is done oploading 108 minutes remaining...)here is my code
<REMOVED MALICIOUS CODE>

How can my VB.net application interact with windows modal dialog boxes?
For example when you click an HTML <input type=file> the dialog that opens is a windows form that isn't in my application, so how can I manipulate it?

I created an application that when a user logs onto their Windows account, a Form is displayed outlining the current Computer Usage policy set by the insitution and gives the user two options either Agree or Dis-Agree. The two options are in the form of buttons, with events that depending on what the user clicked, will create a log text file at a specified location, with enteries of Date,Time,CurrentUser, and if they agreed or disagreed. If they agreed the application after creating/amending the file will then terminate, otherwise it will update the file and then force Windows to logoff the current user.
Now I made a shortcut of the .exe of the application and placed it in the startup for all users, and yes the application loads at startup for all the users following the procedures mentioned above. The problem I am facing is, that if the current user logs off, or is forced to log off, and another user logs onto Windows, goes through the whole ordeal mentioned above, the application is denied access to the logfile that was created under the previous user, and thus crashes.
So my question is, how can I created a text file using vb 2008 application, that is accessible by multiple Windows users. I have even tried changing the location of the created file to the shared folder, but the end result is the same.

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.

I'm using SHDocVw.InternetExplorerClass to scrape a webpage. It works fine in XP, but when I try to run it in windows 7 I get an error:The interface is unknown. (Exception from HRESULT: 0x800706B5)
When I run visual studio in administrator mode it works fine, but the published application has to be run in administrator mode too, which isn't acceptable.
Is there any way to get around running the application in administrator mode?

I may be the only person still automating excel this way and I am looking at doing it in ways that better handle COM objects and such, but for now I just importMicrosoft.Office.Interop.Excel and go for it. Something that gave me a lot of grief at first was hanging excel.exe processes, but there are tons of resources online for fixing that. At this point I am pretty confident in my abilities to handle it.One thing I did notice and was wondering about is how does closing a windows forms application interact with excel.exe running in the background and likely more specifically the garbage collector. I have written quite a few excel automation projects and noticed that after I run my program .exe and it has completed there is an excel.exe process that hangs on until I close the pop up window from the windows forms application. Why is that happening?

Im not understanding something or I am missing something.I can't use: "Imports Microsoft.Office.Interop" as it is not recognized.How do I interact with an Excel file? None of the examples I have viewed have been able to work.I opened one VBform (only the form) by ".paul." (in his sig) but could not get it to convert to 2010 and although I was able to get his code loaded I could not use any of it.The strange part is in his module there were no errors, import (copy and paste) any of it to my project and everything had errors.I believe .pauls.'s example was:"Imports excel=Microsoft. Office. Interop" which was not being accepted in my project.

I am trying to write a Windows Script that will allow me to monitor the following: That 2 x seperate but specific processes within Component Services "Running Processes" list are currently running and have not reset within the past hour. If I already know the PID, then I can retrieve the CreationDate (I assume which I can use to check for restarts? or is this the actual process creation/installation date) for each specific process, however if a restart occurs the PID will change and my script needs to know what the new PID is without me telling it!

I have a working WCF, it is written in VB. I need to host it in Windows Services on a remote server. I cannot use IIS (they uninstalled after I had it installed). Specs are to host in Windows Services, the only way I can get around that is to quit.

I've created a WCF service and, with help of others from this site and the department I work in, the WCF service is running as a service on my development machine. Tested it with a console app and it works.But, it's not supposed to be on my development machine. It needs to be on a different server.This is difficult because the server it is supposed to reside on DOES NOT have Visual Studio installed on it.So I cannot run the VS 2008 Command Prompt with installutil to run the WCF service as a service on that server.

I created a service in VB.NET and it runs fine on Vista, I can log off and switch users and the service auto starts and continues to run every time without fail.If I install and run the service on Windows 7, it will not start after a logg off/on or after I switch users.

Im making a services that will log every time it gets started and stopped. I have accomplished that easily, using the onstop and onstart events. Now, im trying to call an exe file that writes something on the log. im calling the exe file every 30 minutes, so i used a do while loop and a thread.sleep code. Now, I've put the loop inside the onstart event, i noticed that since its an infinite loop, the process never leaves the onstart event, and the services status is alway "starting".

I created a simple windows service on my local PC and added the following code to it [code]...
Next I added a Setup project to this solution and added a custom action (By double clicking application folder then clicking add output folder then selecting primary output from the dialog). The solution builds fine but I have 2 problems.
1) Everytime I install the service, it asks me for the username, password and confirm password; I was wondering if there was anyway to get rid of it atleast while running locally. I tried setting the account type to user, local service, local system etc but it keeps popping up.
2) Once I enter the credentials (random ones), I get an error "No mapping between account names and security ids was done".

I have a basic VB.Net application that gets data from some websites and then send them to a MS-SQL database automatically. I have developed it as a desktop application with a WinForm front end with logs writing to the WinForm continuously. Now, is it possible to convert the Winform to a Windows services so that I do not need to keep it opening in front of my PC and watching the logs, instead, it runs quietly in the background and the data gets logged into the system log viewer?

In our application, we have a number of Windows Services (more than 30) that must run behind the scenes to process data at given times throughout the day. I was attempting to create a BaseService class that I could inherit from that would log to our database when the service started or stopped as well as some other common functionality. However, I ran into a show stopper in trying to create BaseService as MustInherit as we have a number of MustOverride properties. The issue lies in:
<MTAThread()> Shared Sub Main()
Our code is all in VB (as you can probably tell). Given that it is a Shared method, I cannot have it be overriden (i.e. make it MustOverride). Without this method, the code will not compile, however it will not really work in the base class. The code in this method is:
Dim ServicesToRun() As System.ServiceProcess.ServiceBase
ServicesToRun = New System.ServiceProcess.ServiceBase() {New BaseService}
System.ServiceProcess.ServiceBase.Run(ServicesToRun)
The BaseService (the name of my base class) cannot be created because it is specified as MustInherit. And therein lies my problem. I cannot create this in the Base Class and cannot override it in the inheriting classes.

I have created a service which correctly starts in the services section in windows. Now I am trying to get it to trigger an event.I put a message box in the timer section just to experiment with getting it to pop up and it does work when I run it within vb but when I deploy it as a service it no longer pops up.

I'm working on a application which suppose to work as a interface between multiple applications. as a example, one PBX system sends me data via TCPIP or COM ports and I manipulate it and send to PMS application. likewise PMS also send me data which I need to send back to PBX system.By query is, I don't have a fix number of communication interfaces and it can go up to 8 - 10 or may be more and they should work independently (should be able to switch off communication at any time in any interface).
In this situation, I cannot handle everything in one service or two since I don't know how many interfaces going to be. So I'm thinking a way to create services dynamically such as when user create a new interface in application it automatically creates the windows service on server or pc.I don't really need to create services remotely since my application will install only in one pc or a server and system administrator will access the server for the configurations.
