  • Where is asset_host rails 3?

    - by tig
    What happened to asset_host in rails 3? Earlier I can put following code into development.rb and get all assets not present on development: ActionController::Base.asset_host = proc do |source, request| unless File.exist?(File.join(RAILS_ROOT, 'public', source.sub(/\?\d+$/, ''))) 'http://example.com' end end But in rails 3 there is no such method and google does not help me.

  • Inline-SVG not rendering when generated by JS

    - by Lucas Gasenzer
    I want to implement some visual statistics into a jQuery mobile page. If I embed the folowing snippet it will show me the same results as if I would embed it from a separate *.svg-file. <svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" height="115" width="100%"> <rect x="0%" y="0" fill="#8cc63f" width="19.2%" height="100" /> <text x="10%" y="115" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">A</text> <text x="10%" y="15" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">100</text> <rect x="20.2%" y="50" fill="#8cc63f" width="19.2%" height="50" /> <text x="30.2%" y="115" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">B</text> <text x="30.2%" y="65" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">50</text> <rect x="40.4%" y="90" fill="#8cc63f" width="19.2%" height="10" /> <text x="50.4%" y="115" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">C</text> <text x="50.4%" y="85" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">10</text> <rect x="60.6%" y="78" fill="#8cc63f" width="19.2%" height="22" /> <text x="70.6%" y="115" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">D</text> <text x="70.6%" y="73" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">22</text> <rect x="80.8%" y="40" fill="#8cc63f" width="19.2%" height="60" /> <text x="90.8%" y="115" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">E</text> <text x="90.8%" y="55" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">60</text> Now because these statistics obviously change for each site I generate code like the one above using JavaScript. The HTML-Source-Code looks the same but the SVG will not be showing. Instead it looks like this: A 100 B 50 C 10 D 22 E60 so really just a line of text Am I missing something? Thank you for your help!

  • URL conventions for Maps on Windows Phone 7

    - by Stan Wiechers
    What is the best practice for opening a map from the mobile internet explorer on windows phone 7? On BlackBerry you use a JavaScript method and on Android/iOS you simply link to a google maps URL. I am planning to integrate the different ways of opening maps into my mobile geo javascript library and don't have a windows phone device. http://code.google.com/p/geo-location-javascript/ Thanks, Stan Wiechers

  • PAM authentication problem

    - by mdipierro
    I am using this module to authenticate using pam: http://code.google.com/p/web2py/source/browse/gluon/contrib/pam.py I can call authenticate('username','password') and it returns True/ False. It works for any 'username' but 'root'. My guess is that there is a security restriction in PAM that does not allow to check for the root password. I need to be able to check the root password. Is there anything I can change in the pam.conf or somewhere else to remove this restriction?

  • Reading MP3 files

    - by Midas
    I want to read MP3 files in C++ and I prefer to write my own code for this. Basically to learn how the filetype works. I want to read all the bits of hex data of a MP3 file and have my speakers play it. :) I have no idea where to start since I don't yet know how data is actually stored into a MP3 file. Thanks for your help

  • mulformed Farsi characters on AWT

    - by jlover2010
    Hi As i started programming by jdk6, i had no problem in text components neither in awt nor in swing. But for labels or titles of awt components, yes : I couldn't have Farsi characters displayable on AWTs just as simple as Swing by typing them into the source code. lets check this SSCCE : import javax.swing.*; import java.awt.*; import java.io.*; import java.util.Properties; public class EmptyFarsiCharsOnAWT extends JFrame{ public EmptyFarsiCharsOnAWT() { super("????"); setDefaultCloseOperation(3); setVisible(rootPaneCheckingEnabled); } public static void main(String[] args) throws AWTException, IOException { JFrame jFrame = new EmptyFarsiCharsOnAWT(); MenuItem show ; // approach 1 = HardCoding : /* show = new MenuItem("\u0646\u0645\u0627\u06cc\u0634"); * */ // approach 2 = using simple utf-8 saved text file : /* BufferedReader in = new BufferedReader(new FileReader("farsiLabels.txt")); String showLabel = in.readLine(); in.close(); show = new MenuItem(showLabel); * */ // approach 3 = using properties file : FileReader in = new FileReader("farsiLabels.properties"); Properties farsiLabels = new Properties(); farsiLabels.load(in); show = new MenuItem(farsiLabels.getProperty("tray.show")); PopupMenu popUp = new PopupMenu(); popUp.add(show); // creating Tray object Image iconIamge = Toolkit.getDefaultToolkit().getImage("greenIcon.png"); TrayIcon trayIcon = new TrayIcon(iconIamge, null, popUp); SystemTray tray = SystemTray.getSystemTray(); tray.add(trayIcon); jFrame.setIconImage(iconIamge); } } Yes, i know each of three approaches in source code does right when you may test it from IDE , but if you make a JAR contains just this class (and its resources) by means of NetBeans project clean&build ,you won't see the expected characters and will just get EMPTY/BLANK SQUARES ! Unfortunately, opposed to other situations i encountered before, here there is no way to avoid using awt and make use of Swing in this case. And this was just an SSCCE i made to show the problem and my recent (also first) application suffers from this subject. And i think should have to let you know I posted this question a while ago in SDN and "the Java Ranch" forums and other native forums and still I'm watching... By the way i am using latest version of Netbeans IDE... I will be so grateful if anybody has a solution to this damn AWT components never rendered any Farsi character for me... Thanks in advance

  • how to use drawItems() in PyQt?

    - by DSblizzard
    I have these two code fragments in program: class TGraphicsView(QGraphicsView): def __init__(self, parent = None): print("__init__") QGraphicsView.__init__(self, parent) def drawItems(self, Painter, ItemCount, Items, StyleOptions): print("drawItems") Brush = QBrush(Qt.red, Qt.SolidPattern) Painter.setBrush(Brush) Painter.drawEllipse(0, 0, 100, 100) ... Mw.gvNavigation = TGraphicsView(Mw) # Mw - main window Mw.gvNavigation.setGeometry(0, 0, Size1, Size1) Mw.gvNavigation.setScene(Mw.Scene) Mw.gvNavigation.setSceneRect(0, 0, Size2, Size2) Mw.gvNavigation.show() _init_ works, Mw.gvNavigation is displayed and there are Mw.Scene items in it, but drawItems() isn't called. Please explain, what I'm doing wrong.

  • How to tell GDB to flush the stdio of the program being debugged

    - by Yorkwar
    The stdio is usually buffered. When I hit a breakpoint and there's a printf before the breakpoint, the printed string may still be in the buffer and I can not see it. I know I can flush the stdio by adding some flush code in the program. Without doing this, is there any way to tell GDB to flush the stdio of the program being debugged after GDB stops? This way is more friendly when debugging a program.

  • Drupal SQL injection attacks prevention and apostrophe handling in Forms

    - by jini
    in typical PHP applications I used to use mysql_real_escape_string before I did SQL inserts. However I am unable to do that in Drupal so would need some assistance. And without any sort of function like that, user input with apostrophes is breaking my code. Please suggest. Thank You My SQL is as follows: $sql = "INSERT INTO some_table (field1, field2) VALUES ('$field1', '$field2')"; db_query($sql);

  • How do I get the next token in a Cstring if I want to use it as an int? (c++)

    - by Van
    My objective is to take directions from a user and eventually a text file to move a robot. The catch is that I must use Cstrings(such as char word[];) rather than the std::string and tokenize them for use. the code looks like this: void Navigator::manualDrive() { char uinput[1]; char delim[] = " "; char *token; cout << "Enter your directions below: \n"; cin.ignore(); cin.getline (uinput, 256); token=strtok(uinput, delim); if(token == "forward") { int inches; inches=token+1; travel(inches); } } I've never used Cstrings I've never tokenized anything before, and I don't know how to write this. Our T.A.'s expect us to google and find all the answers because they are aware we've never been taught these methods. Everyone in my lab is having much more trouble than usual. I don't know the code to write but I know what I want my program to do. I want it to execute like this: 1) Ask for directions. 2) cin.getline the users input 3) tokenize the inputed string 4) if the first word token == "forward" move to the next token and find out how many inches to move forward then move forward 5) else if the first token == "turn" move to the next token. if the next token == "left" move to the next token and find out how many degrees to turn left I will have to do this for forward x, backward x, turn left x, turn right x, and stop(where x is in inches or degrees). I already wrote functions that tell the robot how to move forward an inch and turn in degrees. I just need to know how to convert the inputted strings to all lowercase letters and move from token to token and convert or extract the numbers from the string to use them as integers. If all is not clear you can read my lab write up at this link: http://www.cs.utk.edu/~cs102/robot_labs/Lab9.html If anything is unclear please let me know, and I will clarify as best I can.

  • bottom uicomponent does not receive mouse events

    - by firemonkey
    HI, I am sure this is very basic, however I am not able to find the solution. I have a base ShapeContainer(UIComponent). I add a uicomponent which has mouse down listener to ShapeContainer. the listener works great. When I add a simple sprite(draw square) on the ShapeContainer, The listener does not work any more. In the code, if I comment below lines, The event listener works fine. var square:Sprite = new Sprite(); square.graphics.lineStyle(4,0x00FF00); square.graphics.drawRect(0,0,20,20); square.mouseEnabled=false; shapeContainer.addChildAt(square,1); I have tried few things like, mouseenabled=false on top sprite. also tried to add addChildAt but non of them did any help. How can I draw a shape and also have the event listener work. enter code here protected function application1_creationCompleteHandler(event:FlexEvent):void { var shapeContainer:UIComponent = new UIComponent(); shapeContainer.x=100; shapeContainer.y=100; shapeContainer.width=200; shapeContainer.height=200; rawChildren.addChild(shapeContainer); var EventListenerShape:UIComponent = new UIComponent(); EventListenerShape.x=100; EventListenerShape.y=100; EventListenerShape.width=200;a EventListenerShape.height=200; EventListenerShape.graphics.clear(); EventListenerShape.graphics.beginFill(0xf1f1f1, 0.1); EventListenerShape.graphics.drawRoundRect(0, 0, 200, 200, 10, 10); EventListenerShape.alpha = 0; EventListenerShape.graphics.endFill(); EventListenerShape.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownfunc); shapeContainer.addChild(EventListenerShape); var square:Sprite = new Sprite(); square.graphics.lineStyle(4,0x00FF00); square.graphics.drawRect(0,0,20,20); square.mouseEnabled=false; shapeContainer.addChildAt(square,1); } private function mouseDownfunc(e:MouseEvent){ trace("mouse Down **"); }    ]]> </mx:Script> <mx:Canvas id="uic" width="100%" height="100%" backgroundColor="0xFFFFFF"> </mx:Canvas>
