阅读更多关于 PHP and MySQL Select a Single Value

问题 I'd like to know how to select a single value from my MySQL table. The table includes columns username and id amongst others ( id is auto-increment and username is unique). Given the username, I want to set a session variable $_SESSION['myid'] equal to the value in the id column that corresponds to the given username.

PHP Count Logged-In Users

阅读更多关于 PHP Count Logged-In Users

问题 I'm having trouble figuring out how I can count the number of logged-in users in my application. What I have: When a user logs in, they get a session (which is used when the user wants to visit a protected page) and the IsLoggedIn column for the user in the users table is set to 1 to indicate that the user is logged in. When the user logs out, the value is set back to 0. Counting the number of 1s in the users table makes it easy to return the number of users logged-in. But... The Problem: If

问题 The tool I develop needs to grant access rights \"Full Control\" to a file created by it. It needs to be read, modified and deleted from all windows accounts and even possible future accounts. Could this be achieved? I know I can try this for a SPECIFIC_USER: FileSystemAccessRule rule = new FileSystemAccessRule(SPECIFIC_USER, FileSystemRights.FullControl, AccessControlType.Allow); FileSecurity fSecurity = File.GetAccessControl(filePath); fSecurity.SetAccessRule(rule); File.SetAccessControl

阅读更多关于 Detect if running as Administrator with or without elevated privileges?

I have an application that needs to detect whether or not it is running with elevated privileges or not.

(For example in vshost.exe). How can I determine whether or not elevation is [already in force or] possible ?

Under Windows Server 2008 with ASP.NET 4.0 installed there is a whole slew of related user accounts, and I can't understand which one is which, how to they differ, and which one is REALLY the one that my app runs under. Here's a list: IIS_IUSRS IUSR DefaultAppPool ASP.NET v4.0 NETWORK_SERVICE LOCAL SERVICE. What is what? Kev This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....
