readfile

I have a file containing text in separate line. I want to display line first, and then if I press a button, the second line should be displayed in the TextView and the first line should disappear. Then, if I press it again, the third line should be displayed and so on. Should I have to use TextSwitcher or anything else? How can I do that? You tagged it as "android-assets" so I'm going to assume your file is in the assets folder. Here: InputStream in; BufferedReader reader; String line; TextView text; public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState);

I am trying to do a string replace for entire file in PHP. My file is over 100MB so I have to go line by line and can not use file_get_contents() . Is there a good solution to this? Dominic Barnes If you aren't required to use PHP, I would highly recommend performing stuff like this from the command line. It's byfar the best tool for the job, and much easier to use. In any case, the sed (Stream Editor) command is what you are looking for: sed s/search/replace oldfilename > newfilename If you need case-insensitivity: sed -i s/search/replace oldfilename > newfilename If you need this to perform

I've seen many questions about how to efficiently use PHP to download files rather than allowing direct HTTP requests (to keep files secure, to track downloads, etc.). The answer is almost always PHP readfile() . Downloading large files reliably in PHP How to force download of big files without using too much memory? Best way to transparently log downloads? BUT, although it works great during testing with huge files, when it's on a live site with hundreds of users, downloads start to hang and PHP memory limits are exhausted. So what is it about how readfile() works that causes memory to blow

1 分为jdk自带代理 2 实现接口 InvocationHandler ，用反射调用方法 3 获取代理类：Proxy.newProxyInstance(cls.getClassLoader(),cls.getInterfaces(), new TestProxy(obj)); 4 5 实例： 6 public interface ReadFile { 7 public void read(); 8 } 9 10 public class Boss implements ReadFile { 11 @Override 12 public void read() { 13 System.out.println("I'm reading files."); 14 } 15 } 16 17 public class Secretary implements InvocationHandler { 18 private Object object; 19 public Secretary(Object object) { 20 this.object = object; 21 } 22 @Override 23 public Object invoke(Object proxy, Method method, Object[] args) throws Throwable { 24

I'm trying to understand why the below promise setups don't work. (Note: I already solved this issue with async.map. But I would like to learn why my attempts below didn't work.) The correct behavior should be: bFunc should run as many time as necessary to fs read all the image files (bFunc below runs twice) and then cFunc console prints "End". Thanks! Attempt 1: It runs and stops at cFunc(). var fs = require('fs'); bFunc(0) .then(function(){ cFunc() }) //cFunc() doesn't run function bFunc(i){ return new Promise(function(resolve,reject){ var imgPath = __dirname + "/image1" + i + ".png"; fs

I have a site architechure where I assign content to variables and then print them in a master page. My problem is that php code in the sub pages is imported into the variables as strings. Is there anyway to make sure that the code is actually executed and the results is imported in the variables instead? In the example below the php code in signup_header.php is imorted as a string to $page_header. The result is that "getVerifiedEmail(); ?>" is displayed in the form element instead of the e-mail address. master.php <!DOCTYPE HTML> <html> <head> <?php echo $page_header; ?> </head> <body id=
