I wrote a program that is a system tray app that has no user interface. The issue is that when you shutdown, log off, or restart the PC the app does not shutdown and the user has the "End Now" message box pop up.
The only thing running on this app is that it is listening to a port for communication.
I do not have any code in the form closing event as that is what I want just to close.
I have made an simple application (.exe). When i run this program local on my machine it works fine. When i run it from an server i get the system.security.securityexception message.

I'm using VS2008, targetting framework 3.5..Every time I reboot the PC, I open up Visual Studio, play with my code a bit, then hit F5 to debug it. I play around with my code some more, then debug again, and end up with the following problems:[code]The previous ten items in the error list are all Warnings, and they've all been in the project for forever, so I don't think they are the issue, here.What is the issue is that Visual Studio refuses delete/copy the XML file, and so will not run. I have to shut down the IDE to fix the issue.

View 1 RepliesI've got a small reminder application I wrote in VB Express 2008. The main app autostarts with Windows and sits in the system tray all the time. Now, I need to save the time (sorta timestamp) it closes/terminates to a file. It works fine when the app is terminated by myself but doesn't when when I shutdown/reboot Windows. The code that saves the timestamp to a file resides in FormClosing event. But for some reason it doesn't fire or the code to save the file doesn't get executed when I shut down/reboot windows.
Is there a way, probably thru' Win API to register my app with Windows, so that windows actually waits for my app to terminate in a sane way after saving the data. I remember of reading about this possibility somewhere, I don't remember now.
anyone know how to fix this? this is what i get when i try to run setup.exe

I have converted a Windows Forms VS2003 application to VS2005 and then to VS2008. It includes a setup project for deploying on the client computer (the regular installer, not click once). It works fine when I run it on my computer, either in VS or if I install using the setup installer. But when I install it on the client computer and then try to run it, I immediately get a System.InvalidOperation exception. I put in debug code before my code but it fails before it gets to any of my code. Both computers are XP. The client comptuter actually has VS2003, though it is not used.
I have tried it with either the 2.0 framework or the 3.5 framework (and included those as prerequisities) but neither makes a difference (and I did set that in the Launch conditions, as well as in the Advanced Compile Options). The application uses CrytalReports for VS.
I don't think I can run JIT debugging on the user computer due to permission issues. Are there any other debugging things I can try to narrow this down or has anyone encountered this.
I have the following code under a button labeled "Exit" for exiting my application. Code:Application.Exit()It has been working fine. I added a reference to System.Deployment and the compiler suddenly doesn't like Application.Exit(). Can I not use Application.Exit() and have a ref to System.Deployment at the same time? Upate: I got it. I used the Object Browser and found "System.Windows.Forms.Application.Exit" which works with System.Deployment referenced

i was under the impression that using the System.Data.OracleClient namespace will allow me to deploy my application without having the client machine install any OracleClient software besides the .Net Framework 2.0 which if i'm not mistaken, contains the System.Data.OracleClient.dll.
but after creating a WinForm application and then publishing it thru ClickOnce , i found myself getting this error when running the application on the client machine. is this a normal behavior or did i do something wrong in the process?

I am using WM_QUERYENDSESSION to detect Windows shutting down in my vb.net app, but the complexity is that I need to quickly load a console application during this code to do some cleanup. It is looking like the console
application is not even loading, even though I can cause delays in the vb.net code. Is there a way to do this?
I have a program with the line process.start("shutdown", "-s -f -t 00") However, when it's executed, everything exits, and the logging off text appears, then the screen blackens out and there's only the mouse pointer. Nothing can be done like opening the task manager, I just have to shut it down using the main button, holding it for 7 sec.

I have a windows forms application that has no form and it runs in the background. It using a webbrowser control to get information off the internet.The program is that when I add the event handler:webbrowser.documentcompleted the program just shuts down. If i put a message box after the event handler then it works just fine because the webrowser has time to load the document. How can I do some like console.readkey that you would do in a console application?

View 6 RepliesI have written an application that sits in the systray and monitors a database for me. The problem is that this application is stopping some of my clients computers from shutting down, I assume because the app is still running when the computer is trying to shut down.
What I need to know is if there is a way that my application can tell when the computer is shutting down, so that I can close my application and therefore allow the computer to shut down.
I am only running my app on Windows O/S e.g. 2000, XP The application is written in VS 2005, .NET 2 and VB.Net language
I was in correspondence with someone using my program and he verified that on his system, XP won't shutdown/restart either if my program is running.
Basically what happens is when XP gets to my program in the shutdown process to terminate it, the whole shutdown/restart just stops. I have to exit my program, then start the shutdown again.
The person sent me an image of some threads that were still running after the shutdown process halted and I was curious if anyone might be able to shed some light on this info and what to do about these threads.
These are the threads that are running and what they do: mscoree.dll - a module containing the .NET Framework functions. mscorwks.dll - Microsoft .NET Runtime Common Language Runtime gdiplus.dll - contains libraries for the GDI graphics interface.
I've build a vb.net windows service which does nothing but ping a wcf webservice and handles sending a maintenance request to this same webservice at night time. It does both tasks using a timer event. If the service does nothing but these two things it says at startup that it's shutting down cause of being idle. The windows service thread needs something todo.[code]....
