问题 I wrote the program code String message = "This is test"; Settings.System.putString(context.getContentResolver(), Settings.Secure.LOCK_PATTERN_ENABLED, message); This is not changing the lock screen text(Owner Info) and Added permission as <uses-permission android:name="android.permission.WRITE_SETTINGS" /> 回答1: Change Settings.Secure.LOCK_PATTERN_ENABLED to Settings.System.NEXT_ALARM_FORMATTED .

问题 I am working on a website in which there would be functionalities to update and delete data on the basis of id.

问题 I have a question regarding a potential security issue/limitation regarding JavaScript hosted on a domain (ex: domain of a CDN, say example.com), but loaded from a website under a different domain (say, example.net). Now imagine that the JavaScript loaded will just read/modify text in a div with a particular id, so nothing "complicated". An example: I have the script loaded from http://example.com/myscript.js, and executed on http://example.net/index.html: [note the different TLD!] <!-- Page

问题 I have been tasked with implementing point 4 in this article: http://support.microsoft.com/kb/900111 This involves using the Membership provider to add a comment to users server side records when they log in and out, and then confirming that when a cookie is used to authenticate, that the user hasn't logged out. This makes perfect sense to me. Where this starts to fall apart is that we do not currently use a membership provider, and so it seems like I face reimplementing all our
