  • Why is run() not immediately called when start() called on a thread object in java

    - by pi
    Or is it? I have a thread object from: Thread myThread = new Thread(pObject); Where pObject is an object of a class implementing the Runnable interface and then I have the start method called on the thread object like so: myThread.start(); Now, my understanding is that when start() is called, the JVM implicitly (and immediately) calls the run() method which may be overridden (as it is in my case) However, in my case, it appears that the start() method is not called immediately (as desired) but until the other statements/methods are completed from the calling block i.e. if I had a method after the start() call like so: myThread.start(); doSomethingElse(); doSomthingElse() gets executed before the run() method is run at all. Perhaps I am wrong with the initial premise that run() is always called right after the start() is called. Please help! The desired again is making executing run() right after start(). Thanks.

  • How to configure Notepad++ (Scintilla) to write below EOF after EOL [on hold]

    - by Piotr Piaseczny
    Is it possible to configure scintilla to "brake" EOL/EOF while writing ? Now, if I want to begin writing in a column after EOL, I use ALT+left mouse button and start typing after click. No idea how to begin writing below EOF. Pressing Enter key many times is the only method now. Other explanation: If You open a new document, doesnt matter what kind of (php/txt etc) all You have is just one line. If You want to write in line 5 - must press Enter 5 times. Every other editor I know (IDE in Builder C++/MultiEdit) "ignore" eof and you can write anywhere in document. Because of php/html I've found notepad++ as a best editor but I'd like to "brake" limitations of (probably) scintilla

  • MS Clear Screen Saver doesn't work

    - by ufoq
    I have a problem with really exotic thing - Microsoft Clear Screen Saver. As it's name suggests, it's a screen saver, that's transparent (MS posted it as a part of W2k Resource Kit). When you move the mouse/hit a key, the "lock" dialog appears. I would like to use this to view servers desktops without need to log in. I tested it on my XP's, and it works flawlessy. But on W2K3 servers it doesn't work. After the screensaver timeout, the error message is displayed: "The Clear Screen Saver cannot display the user desktop after the workstation has been locked"

    - by haansi
    Hi, As per requirement I disabled all validation controls in page on PageLoad event in server side. On clicking submit button I want to activate them and validate the page and if the page is ok submit other wise not. I am able to enable all validaters but one thing that I am unable to understand is that they do not validate the page. I set alerts and check they are being enabled but they do not validate the page and let the page submit. I am sorry I couldn't get where I am wrong, may be there need to call some validation method as well or I should prevent default behavior of button. please guide me. Below is my script: <script type="text/javascript"> function NextClicked() { var _ddlStatus = document.getElementById("<%=ddlEmpStatus.ClientID%>"); var _selectedIndex = _ddlStatus.selectedIndex; if (_selectedIndex == 0) { alert("Nothing selected"); }<br/> else<br/> if (_selectedIndex == 1) { for (i = 0; i < Page_Validators.length; i++) { Page_Validators[i].Enabled = true; } } } </script> thanks in anticipation.

  • Selections and radioing - JavaScript

    - by Wayne
    I have a list like this: <ul> <li id="adm-thumb" onclick="javascript:addBanner('bowling.jpg');"> <div class="adm-tick"></div> <img src="img/banners/bowling.jpg" /></li> <li id="adm-thumb" onclick="javascript:addBanner('kcc.jpg');"> <div class="adm-tick"></div> <img src="img/banners/kcc.jpg" /></li> <li id="adm-thumb" onclick="javascript:addBanner('paintballing.png');"> <div class="adm-tick"></div> <img src="img/banners/paintballing.png" /></li> </ul> <input id="bannername" type="text" /> When one item is clicked, the value inside the addBanner() will be added to the input field, however, I want one list to be selected (which is done by css to make it look like it has) when it is equal to the value of the input value. If the value is equals to the value in the addBanner value then the clicked item should have a red background. e.g. function addBanner(label) { var Field = document.getElementById('bannername'); Field.value = label; if(Field.value != label) { // I have no idea what to put here } } Something like a div button that acts like a radio button.

  • JQuery Delegate and using traveral options in function

    - by Brian
    I am having trouble figuring out how to use the JQuery delegate function to do what I require. Basically, I need to allow users to add Panels (i.e. divs) to a form dynamically by selecting a button. Then when a user clicks a button within a given Panel, I want to be able to to something to that Panel (like change the color in this example). Unfortunately, it seems that references to the JQuery traversing functions don't work in this instance. Can anybody explain how to achieve this effect? Is there anyway to bind a different delegate to the each panel as its added. $('.addPanels').delegate('*', 'click', function() { $(this).parent.css('background-color', 'black'); $('.placeholder').append('Add item'); }); <div class="addPanels"> <div class="panel"> <a href="#" class="addLink">Add item</a> text</div> <div class="placeholder"/> </div> </div>

  • jQuery & PHP: Running action in background

    - by Azzyh
    Hi, so I want to do something like when you press on LogOut, you get a waiting message like "please wait.." while its running ucp.php?mode=logout in the background, and after it has loaded that it should refresh the site. How should this be done?? I am new to jquery, but so far i gave my link a ID, called #logout, made a <div id="message"></div> and then in jquery i did: jQuery(document).ready(function(){ $('#tryout').click(function () { logOut(); }); function logOut() { var postFile = 'ucp.php?mode=logout'; $.post(postFile, function(data){ $("#message").fadeIn('slow'); }); } Now is this right?

  • Codeigniter: Check where model is loaded from?

    - by qwerty
    I'm having the strangest thing ever right now. I "disabled" a model because i don't need to access it ever again. I did so by echoing out an error string in the __construct() and right after that die(). That way i would notice if i ever loaded the model, even by mistake, which should never happen. Alright? The problem is, the model is not loaded ANYWHERE in the entire project, but it still gets loaded for some reason. It's not auto loaded, that's for sure. Is it possible to track down where a model is loaded? Like which line it happens etc?

  • How to calculate the touch location with convertToWorldSpace?

    - by Paul
    i would like to convert the touch location as a world coordinate in my tile game. With this code, i clicked on the right of the screen (so that my character walks in the tiled game, and the background goes slowly to the left) : - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { for( UITouch *touch in touches ) { CGPoint location = [touch locationInView: [touch view]]; location = [[CCDirector sharedDirector] convertToGL: location]; CGPoint test = [self convertToWorldSpace:location]; CCLOG(@"test : %.2g", test.x); The test log gives me : 50, 72, 1e+02, 2.6e+02, 4.2e+02, (and then goes down) 3.2e+02, 9.5, -1.9e+02, etc. Does anyone know why? I would like to calculate the "real" coordinate of the touch, so that i know when the character has to keep going (click on the right of its actual position) or if he has to turn and go backwards. (click on the left of its actual position) Thanks for your help

  • Updating UI objects in windows forms

    - by P a u l
    Pre .net I was using MFC, ON_UPDATE_COMMAND_UI, and the CCmdUI class to update the state of my windows UI. From the older MFC/Win32 reference: Typically, menu items and toolbar buttons have more than one state. For example, a menu item is grayed (dimmed) if it is unavailable in the present context. Menu items can also be checked or unchecked. A toolbar button can also be disabled if unavailable, or it can be checked. Who updates the state of these items as program conditions change? Logically, if a menu item generates a command that is handled by, say, a document, it makes sense to have the document update the menu item. The document probably contains the information on which the update is based. If a command has multiple user-interface objects (perhaps a menu item and a toolbar button), both are routed to the same handler function. This encapsulates your user-interface update code for all of the equivalent user-interface objects in a single place. The framework provides a convenient interface for automatically updating user-interface objects. You can choose to do the updating in some other way, but the interface provided is efficient and easy to use. What is the guidance for .net Windows Forms? I am using an Application.Idle handler in the main form but am not sure this is the best way to do this. About the time I put all my UI updates in the Idle event handler my app started to show some performance problems, and I don't have the metrics to track this down yet. Not sure if it's related.

  • what is the correct way to force existing activities to reload using the new local

    - by pengwang
    have a settings dialog/activity where I allow the user to change the locale. Within that activity i call Resources res = ctx.getResources(); // Change locale settings on the device DisplayMetrics dm = res.getDisplayMetrics(); android.content.res.Configuration conf = res.getConfiguration(); conf.locale = new Locale(language_code.toLowerCase(), coutry_code.toUpperCase()); res.updateConfiguration(conf, dm); and call onChanged() for my settings ListView... everything changes perfectly. Very nice. Then I hit the back button to go back to the previous activity thinking everything should be switched; nope. Everything is still in the previous locale. So I added the above code in the onResume() of the activity thinking that would do it; nope. Also, when I click the menu button of this activity again (not first time) I do not get called in onCreateOptionsMenu() it just displays the previous menu. My question is what is the correct way to force existing activities to reload using the new local?

  • which layout engine for finding coordinates of html elements on the web page?

    - by Mexx
    I am doing some web data classification task and was thinking if I could get the co-ordinates of html elements as they would appear on a web-browser without taking into consideration any css or javascript being referred in the web page. My language of programming is c++ and the need results for a couple million of pages, so it has to be fast. I know there is a Microsoft COM component which renders the page in a web browser control and then can be queried for position of different html tags. But this is not suitable in my case as it first renders the whole page which takes up a lot of time. So as I found out, there are open-source layout engines WebKit, Gecko that can probably be used for this. But that's a huge piece of code and I need someone to direct me to the right classes or right modules to look into or any previous/similar work someone has done previously. Also, please let me know what you guys think is a good choice if I want to customize the existing code for use with multiple threads to make it faster. Thanks

  • monitor power and lock screen (Ubuntu Lucid)

    - by xsznix
    Hi, I'm trying to get my screen to turn off whenever I lock my screen. I know that in Power Management, there's an option to turn off the screen after a set amount of time, and I know about xset dpms force off, but the former doesn't allow me to turn off the screen from the logout menu, and the latter only turns the screen off for a short amount of time (1 minute or so. The screen just turns back on by itself). Is there a script I can modify to change what happens when "Lock screen" from the logout menu is selected, or is there a script I can add to the panel to lock the screen and then turn the monitor off (and turning it back on when I shake the mouse or something)? Thanks.

  • With HTML and CSS, how to have an image that is vertically aligned with a horizontal line?

    - by sungod000
    I'd like the image on the left to be adjacent to the horizontal line on the right (bottoms lining up flush). It should be responsive so that the line can change widths as needed. Right now, the image is sitting on top of the line, not beside it. Here is the HTML <div> <img src="image.png"> <hr> </div> Here is the CSS img { float:left } hr { width:100% } How to make this happen?

  • Windows Phone 7, login screen redirect and a case for .exit?

    - by Jarrette
    I know this has been discussed ad nauseum, but I want to present my case.... 1. My start page in my app is login.xaml. The user logs in, the username and password are authenticated through my WCF service, the username is saved in isolated storage, and then the user is redirected to mainpage.xaml. When a user starts my app, and they already have a saved username in isolated storage, they are redirected to mainpage.xaml If the user hit's "back" hard button from mainpage.xaml, they are redirected to the login screen, which in turn redirects them back to the mainpage.xaml since they already have a saved local username. This is causing my app to fail certification currently since the user cannot hit the "back" button to exit the app from mainpage.xaml. My instinct here is to override the BackKeyPress in mainpage.xaml and exit the app somehow. By reading the other posts, I can see that this method is not available. My second idea was to somehow store a property in the app.xaml.cs page that would tell the app to exit when the login page is loaded and that property is set to true, but that seems a bit hacky as well.... Any ideas here?

  • Computer not booting, black screen, no beeps

    - by Michael Gaddass
    I bought a pre-owned computer on Ebay. It booted fine, had to reset due to it not detecting USB mouse, but it detected the USB keyboard. Booted fine again, then I tried to install Ubuntu Desktop, when it was installing I got a phone call, when I'm answering it, I find a Blue screen of Death. I reboot the computer and nothing, no BIOS boot, no beeping, but one of the fans was on. I opened the cover and found a large amount of dust, removed it, still not booting. I'm a complete novice with computer repairs, the most advanced thing I did was take a 286 harddrive and replace a 486's damaged harddrive with it (put the drive into the 486 that is), what could possibly be causing this?

  • Java, JavaCC: How to check if a char (or char pair) is inside a given UTF32 range?

    - by java.is.for.desktop
    Hello, everyone! I am referring to the XML 1.1 spec. Look at the definition of NameStartChar: NameStartChar ::= ":" | [A-Z] | "_" | [a-z] | [#xC0-#xD6] | [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] | [#x37F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD] | [#x10000-#xEFFFF] If I interpret this correctly, the last range (#x10000-#xEFFFF) goes beyond the UTF16 range of Java's char type. So it must be UTF32, right? So, I need to check pairs of char against this range, instead of single chars, right? My questions are: How do I check for such character ranges using standard Java methods? How is it possible to define such ranges in JavaCC? JavaCC complains about \u10000 and \uEFFFF Thank you! NOTE: Don't worry, I am not trying to write an own XML-parser. I need those character ranges for other reasons.

  • What is the standard way to add an icon to a link with CSS?

    - by ewernli
    I'm used to use padding + background-image to place an icon next to a link. There are many example of this approach. Here is one from here: <a class="external" href="http://www.othersite.com/">link</a> a.external { padding-right: 15px; background: transparent url(images/external-link-icon.gif) no-repeat top right; } But most browser don't print background image, which is annoying. What is the standard to place icon next to links which is semantically correct and works in all cases? (I couldn't find an exact similar question. If there is one, just close this one as duplicate)

  • Stopping work from one thread using another thread

    - by 113483626144458436514
    Not sure if my title is worded well, but whatever :) I have two threads: the main thread with the work that needs to be done, and a worker thread that contains a form with a progress bar and a cancel button. In normal code, it would be the other way around, but I can't do that in this case. When the user clicks the cancel button, a prompt is displayed asking if he wants to really cancel the work. The problem is that work continues on the main thread. I can get the main thread to stop work and such, but I would like for it to stop doing work when he clicks "Yes" on the prompt. Example: // Main thread work starts here t1 = new Thread(new ThreadStart(progressForm_Start)); t1.Start(); // Working for (i = 0; i <= 10000; i++) { semaphore.WaitOne(); if (pBar.Running) bgworker_ProgressChanged(i); semaphore.Release(); if (pBar.IsCancelled) break; } t1.Abort(); // Main thread work ends here // Start progress bar form in another thread void progressForm_Start() { pBar.Status("Starting"); pBar.ShowDialog(); } I could theoretically include a prompt in the cancelWatch() function, but then I would have to do that everywhere I'm implementing this class.

  • Rails - Preventing users from contributing to website when there score is too low - callback / obser

    - by adam
    A User can add a Sentence directly on my website, via twitter or email. To add a sentence they must have a minimum score. If they don't have the minimum score they cant post the sentence and a warning message is either flashed on the website, sent back to them via twitter or email. So I'm wondering how best to code this check. Im thinking a sentence observer. So far my thoughts are in before_create score_sufficient() - score ok = save - score too low = do not save In the case of too low i need to return some flag so that the calling code can then fire off teh relevant warning. What type of flag should I return? False is too ambiguous as that could refer to validation. I could raise an exception but that doesn't sound right or I could return a symbol? Is this even the right approach? What's the best way to code this?
