FileIOPermissio n issue

Hi all,

I have this code sample

FileIOPermissio n fp = new FileIOPermissio n(PermissionSta te.Unrestricted );

fp.Deny();

StreamWriter sw = new StreamWriter(@" c:\test.txt");

sw.Write("Test" );

sw.Close();

I do not understand why the file is still created?

Hello, I wrote a .NET Windows.Forms User Control that needs to be runned through Internet Explorer, like in this article: http://www.15seconds.com/issue/030610.htm. This control needs to 1.)

Hi NG ! I have the following piece of code below. the first try/catch part would return true although I do not have permission to access this computer. The second try/catch part would return false. Do I misunderstand the meaning of FileIOPermission ? >From MSDN: "Controls the ability to access files and folders" ??? Thanks for education! Regards Marcel (Schaf)

Hi there, I have a Windows application that I'm running from a shared drive that needs to access file/directory resources on other drives. I've done a lot of reading, but a lot of the material out there relates to the 1.1 Framework as opposed to 2.0. I've added the following lines to my AssemblyInfo.vb: <Assembly: System.Security.AllowPartiallyTrustedCallers()> <Assembly: System.Security.SecurityTreatAsSafe()>

Hi, I'm trying to test permission to access the file system, using FileIOPermission, but can't seem to get it to work. See my sample app below, for an app that tries to demand a permission to read a specified path, and then calls Directory.GetFiles on that path. The Demands on FileIOPermissions (I tried 3 variations) all work, and then when I call Directory.GetFiles an exception is thrown... saying

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
