问题 I have a .net service running on the local machine (Windows 7 x64, IE8, .net 3.5, C#) that returns a file to the browser in response to a user action. Using firefox or chrome, the file is downloaded properly and our application is launched via a custom mime type and all is well. However, with IE8, I receive a dialog "unable to download file from .

How to get a trusted/verified publisher?

阅读更多关于 How to get a trusted/verified publisher?

问题 When I start my application with administrative permissions (right click on the EXE | Run as administrator), the UAC dialog with an orange or yellow banner appears with the warning that the publisher is unknown.

Basically, I want the look and feel when I start, for example, the calc.exe (Calculator in Windows) with administrative

How do I run my application while a UAC dialog window is showing?

阅读更多关于 How do I run my application while a UAC dialog window is showing?

问题 I have an application that I wrote in .NET. It needs to remain running and have access the desktop that the UAC dialog windows open on and interact with that desktop using keyboard and mouse events. It's sort of like a VNC program. Imagine you are running a VNC program and a UAC window pops up, you want your VNC program to still be able to control the desktop with the UAC window in it so that the user can move the mouse and click the OK button on the UAC dialog. Can anyone tell me how I would

The service runs under the LocalSystem account. The process being started is NOT already running. No virus protection

问题 I'm getting reported errors from users who are receiving the error "System.Security.SecurityException, Requested registry access is not allowed." when trying to read the registry. I can't think why someone would not have permission to read the registry and I'm unable to reproduce the problem on my Windows 7 PC. Affected users are running .NET 4.0 Here's the C# code I'm using: var baseReg = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32); var key = baseReg
