I am trying trite code that will copy information from an infopath document to a word document that is being used as a template containing only a header and footer. The only reason for the code is becausthe footer (not optional) is too long to be handled by Infopath (which has a 255 character limit) and word can hold the full footer. Following the guidance on

Trying to read key "HKLMSOFTWAREPoliciesMicrosoftWindowsWindowsU pdateAU" value "AUOptions" and get the following : A first chance exception of type 'System.Security.SecurityException' occurred in mscorlib.dll Error occurs in ReadRegistry key SOFTWAREPoliciesMicrosoftWindowsWindowsUpdate AU : Requested registry access is not allowed. This occurs in my vb.net application when application is run under an account called OPER in the USERS group. The application :
1/is on my PC's hard drive, its not a web app or on a network share
2/is launched via a desktop click
3/ has a manifest specifying executionlevel "AsInvoker"
It does not occur when the Application is run as an Administrator. It does not occur if I read the value with a non .NET program when logged in as OPER whch makes me think it is a .NET problem not a registry permissions problem. Examining "Effective Permissions" shows that my OPER login has query value permission.I need the application to be able to read the key like the non .NET application while running at USERS level.
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 now spent a long time trying to figure out how to fix this problem, hoping someone here could give me some hints What I'm trying to do: I need a way to save mail items to a folder on the computer What I have done so far: I created a component, where you could drag a mail item from Outlook on to. This component then saves this mail item to a folder on the computer

I have a Visual Basic.Net Windows Forms application to which I am considering adding the WebBrowser control. I'm assuming that the PC's on which this application will ultimately be deployed/installed will have the latest Windows (XP, Vista, or 7) updates, a firewall, and an Internet security suite installed/running.
With this deployment environment in mind, does the WebBrowser control make my application or the deployment PC vulnerable to any significant security risks? Are there any programming issues that should be addressed to eliminate potential security risks when using the WebBrowser control?

View 1 RepliesOut of 70 users of my application 2 are getting the following message when they to run the application... That assembly does not allow partially trusted callers. The reason for the error is that by default .net applications run from a network location have limited permissions. You need to use caspol.exe to add the network folder where your application is being run from to the Trusted Zone. If you do a search on these forums you will find plenty examples of how to do this. It is fairly simple. It will have to be done on every machine that will be running the application and a simple cmd file can be made to do this. The only difference is that I've asked our service desk to install the application to the local C drive which I believe they did.

View 12 RepliesI'm working with a vb.net 2005 project that i converted from vb 6.0 last year. It's working fine in windows xp, but on vista and windows 7 i get an error saying 'Insufficient security permissions to set the system time.'

View 1 RepliesI want to add a feature to my trial version of the application. After first activation, I want to make it limited to 90 days. But I am concerned about user's changing the date of system hence deceiving my application. Is there any possibility to make it fool proof in a way that even if user takes the calender back, application expires after 90 days of first activation? First activation date has been saved in the database.
View 2 RepliesI've written 'File_Reformat_Code.vb' using the "Console Application" template. The program uses SQL to read an Oracle database and then generates fixed-length records for an outside vendor.
It runs fine on my PC and on a file server that's running Windows 2000. But, it gives the following error when I try to run it on a server that's using a Novell operating system. Are their security settings in my program that need to be changed, and, if so, how would I do it? Likewise, for possible settings on the Novell box?

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.

Upate: I got it. I used the Object Browser and found "System.Windows.Forms.Application.Exit" which works with System.Deployment referenced
