由 佐手、 提交于 2019-11-27 04:06:58
问题 Is there a way to detect file renaming using Java? (NIO's WatchService API or any other) From what I've seen when renaming a file two separate events occur - ENTRY_DELETE and then ENTRY_CREATE. 回答1: Take a look at jpathwatch. In addition to the standard watch event kinds specified in Java 7 ( ENTRY_CREATE, ENTRY_DELETE, ENTRY_MODIFY ) it also has additional events called ENTRY_RENAME_FROM and ENTRY_RENAME_TO which will fire when a file is renamed. Note that this depends on whether the

any way to detect volume key presses or volume changes with android service?

由 可紊 提交于 2019-11-27 02:27:04
问题 Some Android apps generate a notification when the device's volume changes and some lock the volume. For the life of me, I cannot find out how that's done. Please, can someone help me by providing an example? 回答1: There is no Broadcast Action to detect volume changes, but you could maybe every second or two check what the volume is with getStreamVolume and if you need to lock it at a specific volume, every second or two use: setStreamVolume Check http://developer.android.com/reference/android

问题 Is there a way to detect the headset's play/pause button click?

How to check the object type on runtime in TypeScript?

由 懵懂的女人 提交于 2019-11-26 20:55:46
I'm trying to find a way to pass an object to function in and check it type in a runtime. This is a pseudo code: func(obj:any){ if(typeof obj === "A"){ // do something } else if(typeof obj === "B"{ //do something else } } a:A; b:B; func(a); But typeof is always return "object" and I could not find a way to get the real type of "a" or "b". The instanceof did not work either and return the same. Any idea how to do it in a TypeScript? Thank you for your help!!! Edit : I want to point out to people coming here from searches that this question is specifically dealing with non-class types, ie object

由 房东的猫 提交于 2019-11-26 20:49:28

By that I mean if uac is turned on (for win vista/7) that I need to determine if the program actually has admin rights (like if the user right clicked and selected "run as administator") and not limited by uac. How do I do this in C++? Win9x: Everyone is "admin" NT4: OpenThreadToken/OpenProcessToken + GetTokenInformation(...,TokenGroups,...) on DOMAIN_ALIAS_RID_ADMINS SID in a loop 2000+: OpenThreadToken/OpenProcessToken + CheckTokenMembership on DOMAIN_ALIAS_RID_ADMINS SID Other alternatives are: IsUserAnAdmin or

Detect if a user has typed an emoji character in UITextView

问题 I have a UITextView and I need to detect if a user enters an emoji character. I would think that just checking the unicode value of the newest character would suffice but with the new emoji 2s, some characters are scattered all throughout the unicode index (i.e. Apple's newly designed copyright and register logos). Perhaps something to do with checking the language of the character with NSLocale or LocalizedString values? Does anyone know a good solution? Thanks! 回答1: Over the years these
