  • Clickin issue in Flash and XML

    - by ortho
    Hi, I have the php backend that displays an xml page with data for flash consuming. Flash takes it and creates a textfields dynamicaly based on this information. I have a few items in menu on top and when I click one of them, data is taken from php and everything is displayed in scroll in flash. The problem is that if I click too fast between menu items, then I get buggy layout. The text (only the text) is becoming part of the layout and is displayed no metter what item in menu I am currently in and only refreshing the page helps. var myXML:XML = new XML(); myXML.ignoreWhite=true; myXML.load("/getBud1.php"); myXML.onLoad = function(success){ if (success){ var myNode = this.firstChild.childNodes; var myTxt:Array = Array(0); for (var i:Number = 0; i<myNode.length; i++) { myTxt[i] = "text"+i+"content"; createTextField(myTxt[i],i+1,65,3.5,150, 20); var pole = eval(myTxt[i]); pole.embedFonts = true; var styl:TextFormat = new TextFormat(); styl.font = "ArialFont"; pole.setNewTextFormat(styl); pole.text = String(myNode[i].childNodes[1].firstChild.nodeValue); pole.wordWrap = true; pole.autoSize = "left"; if(i > 0) { var a:Number = eval(myTxt[i-1])._height + eval(myTxt[i-1])._y + 3; pole._y = a; } attachMovie("kropka2", "test"+i+"th", i+1000); eval("test"+i+"th")._y = pole._y + 5; eval("test"+i+"th")._x = 52; } } } I tried to load the info and ceate text fields from top frame and then refer to correct place by instance names string e.g. budData.dataHolder.holder.createTextField , but then when I change between items in menu the text dissapears completely untill I refresh the page. Please help

  • log4j performance

    - by Bob
    Hi, I'm developing a web app, and I'd like to log some information to help me improve and observe the app. (I'm using Tomcat6) First I thought I would use StringBuilders, append the logs to them and a task would persist them into the database like every 2 minutes. Because I was worried about the out-of-the-box logging system's performance. Then I made some test. Especially with log4j. Here is my code: Main.java public static void main(String[] args) { Thread[] threads = new Thread[LoggerThread.threadsNumber]; for(int i = 0; i < LoggerThread.threadsNumber; ++i){ threads[i] = new Thread(new LoggerThread("name - " + i)); } LoggerThread.startTimestamp = System.currentTimeMillis(); for(int i = 0; i < LoggerThread.threadsNumber; ++i){ threads[i].start(); } LoggerThread.java public class LoggerThread implements Runnable{ public static int threadsNumber = 10; public static long startTimestamp; private static int counter = 0; private String name; public LoggerThread(String name) { this.name = name; } private Logger log = Logger.getLogger(this.getClass()); @Override public void run() { for(int i=0; i<10000; ++i){ log.info(name + ": " + i); if(i == 9999){ int c = increaseCounter(); if(c == threadsNumber){ System.out.println("Elapsed time: " + (System.currentTimeMillis() - startTimestamp)); } } } } private synchronized int increaseCounter(){ return ++counter; } } } log4j.properties log4j.logger.main.LoggerThread=debug, f log4j.appender.f=org.apache.log4j.RollingFileAppender log4j.appender.f.layout=org.apache.log4j.PatternLayout log4j.appender.f.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n log4j.appender.f.File=c:/logs/logging.log log4j.appender.f.MaxFileSize=15000KB log4j.appender.f.MaxBackupIndex=50 I think this is a very common configuration for log4j. First I used log4j 1.2.14 then I realized there was a newer version, so I switched to 1.2.16 Here are the figures (all in millisec) LoggerThread.threadsNumber = 10 1.2.14: 4235, 4267, 4328, 4282 1.2.16: 2780, 2781, 2797, 2781 LoggerThread.threadsNumber = 100 1.2.14: 41312, 41014, 42251 1.2.16: 25606, 25729, 25922 I think this is very fast. Don't forget that: in every cycle the run method not just log into the file, it has to concatenate strings (name + ": " + i), and check an if test (i == 9999). When threadsNumber is 10, there are 100.000 loggings and if tests and concatenations. When it is 100, there are 1.000.000 loggings and if tests and concatenations. (I've read somewhere JVM uses StringBuilder's append for concatenation, not simple concatenation). Did I missed something? Am I doing something wrong? Did I forget any factor that could decrease the performance? If these figures are correct I think, I don't have to worry about log4j's performance even if I heavily log, do I?

  • LaTeX not compiling properly

    - by celenius
    I'm using TeXshop, Natbib, Hyperef and two-column layout, and I am getting the following message: \pdfendlink ended up in different nesting level than \pdfstartlink which prevents LaTeX from compiling. I've searched online for solutions, but most of them are from a few years back, and I don't understand them. Is there anything I should be doing to prevent this error? It appears to be happening due to where the pagebreaks are occurring. Examples of solutions 1, 2

  • Does Apple approve a kind of mark-up language for AppStore?

    - by Eonil
    AppStore now rejects applications made with non-Apple like languages. (with modified contract) However, is it allowed using declarative mark-up language formed with XML? (like XHTML, but different schema) The declarative mark-up is a code too, but not a script or logic code. Just a passive, static data, but forms some layout and part of an application logic.

  • What are the DB smells?

    - by Jonas Byström
    We all know 'code smells', but what are the fundamental 'database smells'? I'm a DB n00b, but I'll give an example of something that I find fishy. It seems to me like when I have to join 6-8 tables together to optimize our loading that we have a DB smell? Or would that be a pretty 'normal' database layout? (Sure, early optimization is the root of all evil, but this seems to me like early pessimisation, not to mention the cumbersomeness?)

  • When does IE7 recompute styles? Doesn't work reliably when a class is added to the body.

    - by Kid A
    I have an interesting problem here. I'm using a class on the element as a switch to drive a fair amount of layout behavior on my site. If the class is applied, certain things happen, and if the class isn't applied, they don't happen. The relevant CSS is roughly like this: .rightSide { display:none; } .showCommentsRight .rightSide { display:block; width:50%; } .showCommentsRight .leftSide { display:block; width:50%; } And the HTML: <body class="showCommentsRight"> <div class="container"></div> <div class="leftSide"></div> <div class="rightSide"></div> </div> <div class="container"></div> <div class="leftSide"></div> <div class="rightSide"></div> </div> <div class="container"></div> <div class="leftSide"></div> <div class="rightSide"></div> </div> </body> I've simplified things but this is essentially the method. The whole page changes layout (hiding the right side in three different areas) when the flag is set on the body. This works in Firefox and IE8. It does not work in IE8 in compatibility mode. What is fascinating is that if you sit there and refresh the page, the results can vary. It will pick a different section's right side to show. Sometimes it will show only the top section's right side, sometimes it will show the middle. I have tried a validator (to look for malformed html), double css formatting, and making sure my IE7 hack sheet wasn't having an effect. So my question is: * Is there a way that this behavior can be made reliable? * When does IE7 decide to re-do styling? Thanks everyone.

  • Parse HTML with CSS or XPath selectors?

    - by ovolko
    My goal is to parse HTML with lxml, which supports both XPath and CSS selectors. I can tie my model properties either to CSS or XPath, but I'm not sure which one would be the best, e.g. less fuss when HTML layout is changed, simpler expressions, greater extraction speed. What would you choose in such a situation?

  • measure rendered html in javascript without affecting the measurement

    - by drawnonward
    I am doing pagination in javascript. This is typographic pagination, not chopping up database results. For the most part it works, but I have run into a heisenberg issue where I cannot quite measure text without affecting it. I am not trying to measure text before it is rendered. I want the actual position it shows up at on screen, so I can paginate to where it is naturally wrapped. I am measuring the vertical position of characters, not the horizontal width of strings. The way I do this is similar to this answer in that I am applying a style to a block of text, then measuring the position of the newly created span. If the span does not reach the end of the page, I clear it and make a new span in a linear search. The problem is that the anti-aliased sub-pixel text layout is different when the span is applied. In rare cases, this causes the text to wrap differently when I measure it. I have only seen this when wrapping at a hyphen, and I assume it would not happen when wrapping at white space. As a concrete example, "prepared-he" is the string I am having trouble with. When I measure up to "prepare" it appears, as expected, to be within the current page. When I measure "prepared" the whole phrase wraps down to the next line, moving it to the next page, so it looks like the "d" is the character to break at. I break the text between "prepare" and "d-he" and that is wrong. Trying to evaluate individual characters opens a whole can of worms I would rather avoid. The wrapping changes because, with the new span, the line is 1 pixel wider. A solution to my problem could either be a better way to measure text using javascript, or a way to wrap text in a new element without affecting layout. I have tried setting margin-right:-1px for the class of the span being created to wrap the text. This had no noticeable effect. I am doing this in a UIWebView on the iPhone. There are some measurement related calls that are available in normal WebKit that are not available here. For example, Range does not have getBoundingClientRect or support setting an offset other than 0 in setStart or setEnd. Thank you

  • Restrict number of lines in html JLabel

    - by Mike
    I have a JLabel that needs to display some html-formatted text. However, I want to restrict this to being 4 lines long (and if so, provide a button to see everything). So far, I've tried setting the maximum size manually or via a layout manager. However, both of these solutions can cause part of a line to be displayed.

  • How to put a background image on GridBagLayout

    - by Loligans
    I am trying to work with layout managers for the first time, and they are just kicking me in the teeth. I am trying to make a background image and then put buttons on top, using GridBagLayout, if there is a a better layoutmanager please do tell. As for trying to learn how to use layout managers, its very difficult and any learning references would also be much appreciated. This is what it looks like currently, I can get the frame to show the full image, but when i use gridlayout manager, it does that public void addComponentsToPane(Container pane){ BackgroundImage image = new BackgroundImage(); JButton button1, button2, button3, button4, button5; pane.setLayout(new GridBagLayout()); GridBagConstraints c = new GridBagConstraints(); if(shouldFill){ c.fill = GridBagConstraints.NONE; } button1 = new JButton("Button 1"); if (shouldWeightX) { c.weightx = 0.5; } c.fill = GridBagConstraints.HORIZONTAL; c.gridx = 1; c.gridy = 0; button1.setOpaque(false); pane.add(button1, c); button2 = new JButton("Button 2"); c.fill = GridBagConstraints.HORIZONTAL; c.weightx = 0.5; c.gridx = 0; c.gridy = 0; button2.setOpaque(false); pane.add(button2, c); button3 = new JButton("Button 3"); c.fill = GridBagConstraints.HORIZONTAL; c.weightx = 0.5; c.gridx = 2; c.gridy = 0; button3.setOpaque(false); pane.add(button3, c); button4 = new JButton("Long-Named Button 4"); c.fill = GridBagConstraints.HORIZONTAL; c.ipady = 40; //make this component tall c.weightx = 0.0; c.gridwidth = 3; c.gridx = 0; c.gridy = 1; pane.add(button4, c); button5 = new JButton("button 1"); c.fill = GridBagConstraints.HORIZONTAL; c.ipady = 0; //reset to default c.weighty = 1.0; //request any extra vertical space c.anchor = GridBagConstraints.PAGE_END; //bottom of space c.insets = new Insets(10,0,0,0); //top padding c.gridx = 1; //aligned with button 2 c.gridwidth = 2; //2 columns wide c.gridy = 2; //third row pane.add(button5, c); c.ipadx = 800; c.ipady = 400; pane.add(image, c); } This is what i'm trying to make it look like
