In Windows Vista/7/2008/2008R2, is it at all possible to launch a process in a user's session from a service? Specifically, the local session would be most useful.Everything I've been reading seems to say this isn't possible, but I figured I'd ask here before giving up completely.My service signs on as Local System.

I created a function that allows me to login to my web service. I created a session here and added some values I retrieved from a stored procedure.[code].....
My question is: I have a default.aspx and a master page, how can I redirect the user when their session is active? For example, the default page tells users that access is forbidden untill the login/register.Do I have to use the form load handler for default.aspx or the masterpages' load handler? How do I check weither the usersession is active?
I have a Windows Service that needs to start other processes under a user context other than that used by the service. I've seen other posts related to this but have seen no resolutionI've tried many things and have been unsuccessful in starting the process from a Windows Service when a username, password is supplied. orking as it's a requirement of our system to do this and it worked fine until recently and only fails on Vista and Windows 7 (works on XP).
The following code is used to start the process.
Dim P As New Process
P.StartInfo.Domain = Domain
[code].....
The original code came from AutoItI just rewrote what was necessary for VB.NET and added the structures and throws. If successful the PID of the process started is returned, else an exception is thrown. No imports needed.
View 3 RepliesI am trying to startup a simple VB.net program that has a GUI from a service. I have tried a few flavors of Process.Start and none of them allow the GUI to work. I can get the farthest using:
System.Diagnostics.Process.Start(
"C:ProgramDataWatcherStartIt.bat")
And from inside the batch:
start C:TestTestStart.exe
Eventually I get an "Interactive Services Detection" dialog telling me that a message is trying to be displayed and when I click View the message, I see my expected dialog but the program won't run. I am Running on Win7 Home 64 bit. My Simple GUI program was written in VB.net VS2008. I set the service properties to "allow interaction with the desktop" but this does not help.Is there any way to launch a program from within a service that will allow you to interact with the desktop?
I run the app under current logged in user from the service.To give you background, I have a VB.NET Windows service whose sole functionality is to run a Winform App at a specified time. Apart from that it also sets a system wakeup timer so that the system can be woken up at the specified time, if it goes into standby/sleep, to run the app. This service has to cater to XP/Vista/Win7 desktops on our network. This service won't run on servers and laptops.
The Winform App shows a UI for the user to provide some inputs. If the user does not provide the input within 15 minutes, then it defaults the value and then goes into system tray icon. The user can click on the icon and change the values later (within in a specified time frame and that too only twice).
There is absolutely no interaction between the service and the winform app apart from the service starting the app. It also monitors if the app has been killed by the user/crashed. If it has been killed/crashed, then a new instance is run after 30 mins from previous run.
If there is no user logged on, then also I want the app to be run at the specified time. As I said before, the app has a default timer. So if some user has just logged off from the system, then defaults would be set by the winform app.Now coming to why I am stuck with this design - I cannot use TaskScheduler because it has been disabled on all machines and security team is not willing to change it. TaskScheduler had the option to wakeup the machine from sleep and other things. So basically I ended up creating a service which is acting like task scheduler.
Currently when I run the app.exe via process.start() within the service, its running under SYSTEM account as the service is also running under LOCAL SYSTEM. So basically I am not getting any UI. Is there anyway to run it under the current logged in user? I am not worried about multiple user login as we wont be running it on servers and switch user is not enabled on our desktops. Even if somebody has done a remote login via mstsc, then also I need the run the app and show the UI to the user.
I need to launch a VB6 application (which i am already doing fine with the Process namesapce) but I would like to be able to send status updates back to the VB.Net app which fired up the process. I looked into the standardinput and standardoutput but it looks like that is only intended for console apps. Any suggestions on methods to do that? I need something that is bullet proof and instant. I dont want to write logs out to a file and use filesystemwatcher to monitor for changes.
View 2 RepliesI am working on an application that needs to launch Microsoft Word, and then resume when the user closes Word. The code below should work, but it does not. I get an 'object not set to an instance of an object'
1 Dim pInfo As New ProcessStartInfo
2 Dim P As New Process
3 pInfo.FileName = "C: estLLR.doc"
4 P = Process.Start(pInfo)
5 ''# Here is where it goes bad
6 P.WaitForInputIdle()
7 P.WaitForExit()
I put p into the watch window and it shows a a system.diagnostics.process in the watch after line2, but after line 4 it return to NOTHING. The process launches, but I can not monitor it any longer with lines 6 & 7. Is this a 'limitation' of Visual Studio 2010 or am I making an operator error? The MS Help does not show process available in the 2010 version (it is in Visual Studio 2005 and Visual Studio 2008).

I have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).
View 4 RepliesI have VB.NET application in which one of the form has IE control in it, the application starts initially with memory size consumed around 9 MBs, but when IE form is launched, the memory consumed rises to 27 MB, and when that form is closed, the memory reduces merely by 3-4 MBs, so why memory allocated to IEFrame is not de-allocated automatically?
View 3 RepliesI am building an internal web page which retrieves binary data from a SQL database, converts the binary to an image file, then opens the file on the clients PC.In debug mode, this works fine, because the program downloads the file successfully into a temporary directory, converts it to the image then uses System.Diagnostics.Process.Start() to launch the image file in the associated image viewing program.However, as soon as I upload it to the server, two undesired things happen:
a. The file gets saved on the servers temporary directory, instead of the client temporary directory (I kind of expected this to happen, so this wasnt much of a suprise)
b. System.Diagnostics.Process.Start() does not launch the file successfully. Nothing actually happens when it gets to this part of code, however I suspect that it is trying to launch the process on the server end, instead of the client end.
how I can get System.Diagnostics.Process.Start() to launch on the client end OR how I could get the image to just appear in the clients web browser instead?
I want to launch a java executable (let's call it MyApp.jar) from .Net using System.Diagnostics.Process.Start. What's the syntax in VB.Net? The command line syntax is this (if I recall it correctly - because i tried it a few days ago and it worked).
java.exe -jar MyApp.jar pathToSourceFile pathToDestFile
How do I run this command in VB.Net, using System.Diagnostics.Process.Start, assuming I have the following three string variables in VB.Net
pathToJavaExe
pathToSourceFile
pathToDestFile
I want to launch a browser session from a Windows App to load a specified file using system.diagnostics.process.start("http://www.abc.com/doc1.doc") but I'd also like to specify that there shouldn't be a toolbar etc. on the browser window. Is this possible?
View 6 RepliesI 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

Is there a way to do a Session.Abandon() when the user just kills the session by X'ing out with the little red X box in the upper right corner? I am seeing situations where after an "X out", the user comes back in and it seems like session variables are still present? I guess explorer keeps them intact? (I am unsure of this).

i wana create session content all of these fields to use some of them in ctrls.
I keep a Session variable when the user is logged in. So that when the user click on btnLogout it must clear all my sessions and Log the User out for GOOD!!!
It does clear my sessions but if i click the BACK button in IE right after i logged out then i am still logged in! Meaning it goes back to screen where the user was still logged into.

Session.Clear();

I'm using Process.Start method to launch another application from my application. Until today, there was no problem. But I have tested my application in a different OS, Windows XP (SP3), and my application didn't work right on that. I'm also using arguments to run that application. I guess for some reason my application couldn't send arguments to other application correctly under Windows XP. Maybe it is related to my code. But you should know, it works great on Windows 7.

View 2 RepliesI've been trying off and on for a week now to get this to work but no luck. I have completely stripped down my vb.net 2008 windows service to just create a vbs file and launch it using a process.I'm dying here. The vbs file creates and is valid. I can execute it manually, the windows service just won't run it!! I'm on a windows 7 machine and the process is compiled and installed as a 32 bit process. It is also installed as local system.
After the process tries to execute, I created a text file and it did so successfully. So, I know that the service isn't crashing out.[code]....
