• terminating java applet thread on page unload

  - by Hammad Tariq

  Hello, I have got a problem here in terminating the threads. The problem is that I am using applet thread to access JS DOM and manipulate innerHTML of a span to right the Thread Name as the innerHTML. It works fine until I keep refreshing the page but if I dont give it a sleep of like 200ms and go to another page which dont have any applet on it, it will give me an error in firebug console: document.getElementById("userName") is null What I am suspecting is, although I send an interrupt on stop and I have also tried the same by setting a flag variable of running in run while loop, the thread executes much faster than the time JVM takes to unload it and I get my page changed in browser but applet is still trying to find an element with id userName. Is that true? Is there any work around of it? Is there any way to know how many threads are running at the moment? Is there any kill all command to send on destroy()? I have searched a lot, seen all the API of java threads and applets, couldn't get this to work. Below is the code: import java.applet.Applet; import netscape.javascript.*; //No need to extend JApplet, since we don't add any components; //we just paint. public class firstApplet extends Applet { /** * */ private static final long serialVersionUID = 1L; firstThread first; boolean running = false; public class firstThread extends Thread{ JSObject win; JSObject doc; firstThread second; public firstThread(JSObject window){ this.win = window; } public void run() { try{ System.out.println("running... "); while (!isInterrupted()){ doc = (JSObject) win.getMember("document"); String userName = Thread.currentThread().getName(); //String userName = "John Doe"; String S = "document.getElementById(\"userName\").innerHTML = \""+userName+"\";"; doc.eval(S); Thread.sleep(5); } }catch(Exception e){ System.out.println("exception in first thread... "); e.printStackTrace(); } } } public void init() { System.out.println("initializing... "); } public void start() { System.out.println("starting... "); JSObject window = JSObject.getWindow(this); first = new firstThread(window); first.start(); running = true; } public void stop() { first.interrupt(); first = null; System.out.println("stopping... "); } public void destroy() { if(first != null){ first = null; } System.out.println("preparing for unloading..."); } } Thanks

• .net code readability and maintainability

  - by george9170

  There Currently is a local debate as to which code is more readability We have one programmer who comes from a c background and when that programmer codes it looks like string foo = "bar"; if (foo[foo.Length - 1] == 'r') { } We have another programmer that doesn't like this methodology and would rather use if (foo.EndsWith("r")) { } which way of doing these types of operations is better?

• javascript eval backslash in window NT path problem

  - by Hammad Tariq

  I am experiencing a classic JS case (in my opinion) but after a lot of googling, still not able to find a solution. Backslash is considered as a escape character in JS but what you need when you need to pass windows path from the JS and print it? I am using eval because my java applet is executing the code and placing bits when it has a string to evaluate. That's why eval is necessary, however I have made an example which is below: <div id="mainTabs"></div> <script> var s = "document.getElementById('mainTabs').innerHTML='\\C\ganye\file.doc'"; eval(s); </script> I tried double backslashes, not working, if anyone could help me get around this with as less hassle as possible, I will feel grateful.

• How do you get your self focused with so many distractions around? (which you can't or don't want to

  - by Teja Kantamneni

  This question is definitely for a programmer and is centric towards a programmer. But if somebody feels it should not belong here I would not mind deleting it. I don't think this need to go as a WIKI, but if feel like it is a WIKI, I can do that too. The Question is: As a programmer you have to keep yourself up to date with the latest technologies and for that every programmer will generally follow some technology blogs and some social networking sites like (twitter, FB, SO, DZONE etc), how to keep your self focused on the things and still want to follow the technology trends? No Subjective or argumentative answers, Just want to know what practices other fellow programmers do for this...

• learning on the clock

  - by T. Webster

  Some might argue this question is too general, but because keeping up seems especially relevant to programming, is anyone's experience that: do employers expect you to stay current? what is the "industry standard" of expected time a programmer should spend keeping up-to-date? is it generally acceptable that a programmer can spend some time during working hrs on meeting the expectation to keep skills current? If not, how do most programmers find the time? -

  At this website I find amazing questions for programmers. Then I realized that I don't discuss these questions with my colleagues as often. You see, we're all programmers and we are supposed to have talked about these, (in a everyday conversation what we can talk would be more meaningful because it's faster) but we don't. So what about you? Do you enjoy discussing interesting programmer related topics with your programmer friends?

• Enterprise VS Regular corporate developer

  - by Rick Ratayczak

  Ok, I "almost" lost a job offer because I "didn't have enough experience as an enterprise software engineer". I've been a programmer for over 16 years, and the last 12-14 professionally, at companies big and small. So this made me think of this question: What's the difference between a software engineer and an enterprise software engineer? Is there really a difference between software architecture and enterprise architecture? BTW: I try to do what every other GOOD software programmer does, like architecture, tdd, SDLC, etc.

• Can we compare programming languages ergonomically?

  - by Nick Rosencrantz

  For instance, would Python be a more ergonomic programming language since it doesn't force you to make curly braces which requires the AltGr key. Also Python usually requires less code to achieve the same or am I being biased towards Python and PHP actually is an ergonomical and comfortable language despite forcing the programmer to use the AltGr key? Isn't forcing the programmer to use the AltGr key not very ergonomical?
