问题 I've a custom installer program that has worked fine, but it asks the user for admin permission every time it updates an application.

问题 I am trying to take ownership of a file and delete it via C#. The file is iexplorer.exe, current owner by default - TrustedInstaller. The method FileSecurity.SetOwner seems to set the specified ownership, but actually doesn't change the initial owner and throws no exception. Obviously, the next attempt to delete the file throws an exception. What should be changed in the code to take ownership of the file and delete it ? var fileS = File.GetAccessControl(@"C:\Program Files (x86)\Internet

问题 I am trying to set the owner of a file to another user programmatically in C++. I have definitely enabled the SeRestorePrivilege for my process. I can confirm this using Process Explorer. I start the process, it is disabled, I run my code to enable it, ProcExp reports it as enabled, I go just up to the point where the owner is to be set, and it is still enabled (i.e. I am not accidentally disabling it). What other caused can there be for this access is denied message? What have I not

File sharing not working as expected

问题 I have a file sharing issue where my process is trying to read a log file whilst it is currently still open by NLog. In diagnosing the issue, I found something surprising. The following fails: using (var fileStream1 = new FileStream("test.file", FileMode.Append, FileAccess.Write, FileShare.Read)) using (var fileStream2 = new FileStream("test.file", FileMode.Open, FileAccess.Read, FileShare.Read)) { } The second FileStream constructor call fails with: System.IO.IOException was unhandled
