  • How do I translate a ISO 8601 datetime string into a Python datetime object?

    - by Andrey Fedorov
    I'm getting a datetime string in a format like "2009-05-28T16:15:00" (this is ISO 8601, I believe) one hack-ish option seems to be to parse the string using time.strptime and passing the first 6 elements of the touple into the datetime constructor, like: datetime.datetime(*time.strptime("2007-03-04T21:08:12", "%Y-%m-%dT%H:%M:%S")[:6]) I haven't been able to find a "cleaner" way of doing this, is there one?

  • Python List length as a string

    - by mvid
    Is there a preferred (not ugly) way of outputting a list length as a string? Currently I am nesting function calls like so: print "Length: %s" % str(len(self.listOfThings)) This seems like a hack solution, is there a more graceful way of achieving the same result?

  • How do you make a character jump, both on objects and just normal jump?

    - by haxerflaxer
    Hi, I'm kind of a beginner when it comes to java programming, and I have a project in school where I'm going to create a game much like Icy Tower. And my question is, how am I going to write to make the character stand on the ground and be able to jump up on objects? Here's my code so far: Part one package Sprites; import java.awt.Image; import java.awt.event.KeyEvent; import javax.swing.ImageIcon; public class jumper { private String jump = "oka.png"; private int dx; private int dy; private int x; private int y; private Image image; public jumper() { ImageIcon ii = new ImageIcon(this.getClass().getResource(jump)); image = ii.getImage(); x = 50; y = 100; } public void move() { x += dx; y += dy; } public int getX() { return x; } public int getY() { return y; } public Image getImage() { return image; } public void keyPressed(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_LEFT) { dx = -5; ImageIcon ii = new ImageIcon(this.getClass().getResource("oki.png")); image = ii.getImage(); } if (key == KeyEvent.VK_RIGHT){ dx = 5; ImageIcon ii = new ImageIcon(this.getClass().getResource("oka.png")); image = ii.getImage(); } if (key == KeyEvent.VK_SPACE) { dy = -5; } if (key == KeyEvent.VK_DOWN) { dy = 5; } } public void keyReleased(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_LEFT) { dx = 0; } if (key == KeyEvent.VK_RIGHT){ dx = 0; } if (key == KeyEvent.VK_SPACE) { dy = 0; } if (key == KeyEvent.VK_DOWN) { dy = 0; } } } Part two package Sprites; import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.Toolkit; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.KeyAdapter; import java.awt.event.KeyEvent; import javax.swing.JPanel; import javax.swing.Timer; public class board extends JPanel implements ActionListener { private Timer klocka; private jumper jumper; public board() { addKeyListener(new TAdapter()); setFocusable(true); setBackground(Color.WHITE); setDoubleBuffered(true); jumper = new jumper(); klocka = new Timer(5, this); klocka.start(); } public void paint(Graphics g) { super.paint(g); Graphics2D g2d = (Graphics2D)g; g2d.drawImage(jumper.getImage(), jumper.getX(), jumper.getY(), this); Toolkit.getDefaultToolkit().sync(); g.dispose(); } public void actionPerformed(ActionEvent e) { jumper.move(); repaint(); } private class TAdapter extends KeyAdapter { public void keyReleased(KeyEvent e) { jumper.keyReleased(e); } public void keyPressed(KeyEvent e) { jumper.keyPressed(e); } } } Part three package Sprites; import javax.swing.JFrame; public class RType extends JFrame { public RType() { add(new board()); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(800, 600); setLocationRelativeTo(null); setTitle("R - type"); setResizable(false); setVisible(true); } public static void main(String[] args) { new RType(); } } I really appreciate all the help I can get!

  • Programmatically determine whether to describe an object with "a" or "an"?

    - by MarathonStudios
    I have a database of nouns (ex "house", "exclamation point", "apple") that I need to output and describe in my application. It's hard to put together a natural-sounding sentence to describe an item without using "a" or "an" - "a house is BIG", "an exclamation point is SMALL", etc. Is there any function, library, or hack i can use in PHP to determine whether it is more appropriate to describe any given noun with A or AN?

  • Django admin - remove field if editing an object

    - by John McCollum
    I have a model which is accessible through the Django admin area, something like the following: # model class Foo(models.Model): field_a = models.CharField(max_length=100) field_b = models.CharField(max_length=100) # admin.py class FooAdmin(admin.ModelAdmin): pass Let's say that I want to show field_a and field_b if the user is adding an object, but only field_a if the user is editing an object. Is there a simple way to do this, perhaps using the fields attribute? If if comes to it, I could hack a JavaScript solution, but it doesn't feel right to do that at all!

  • How do I find the install directory of a Windows Service, using C#?

    - by endian
    I'm pretty sure that a Windows service gets C:\winnt (or similar) as its working directory when installed using InstallUtil.exe. Is there any way I can access, or otherwise capture (at install time), the directory from which the service was originally installed? At the moment I'm manually entering that into the app.exe.config file, but that's horribly manual and feels like a hack. Is there a programmatic way, either at run time or install time, to determine where the service was installed from?

  • Jquery only works the first time

    - by Tripping
    I am trying to teach myself general web development skills. I am trying to create a image upload with preview functionality using HTML5 FileAPI. Till now, I have created a file input which shows the preview of image when selected. Html mark up is below: <div> <!-- Photos --> <fieldset> <legend>PropertyPhotos</legend> <div class="upload-box" id="upload-box-1"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_1" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File1) @Html.ValidationMessageFor(model => model.File1) </div> </div> <div class="upload-box" id="upload-box-2"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_2" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File2) @Html.ValidationMessageFor(model => model.File2) </div> </div> <div class="upload-box" id="upload-box-3"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_3" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File3) @Html.ValidationMessageFor(model => model.File3) </div> </div> </fieldset> </div> The Jquery to show preview and then display the next "upload-box" is as follows: <script type="text/javascript"> $(document).ready(function () { // show first box $("#upload-box-1").fadeIn(); //Get current & next step index var stepNum = $('div.upload-box').attr('id').replace(/[^\d]/g, ''); var nextNum = parseInt(stepNum)+1; //Get the preview image tag var preview = $('#preview_'+stepNum); //Load preview on file tag change and display second upload-box $('#File'+stepNum).change(function (evt) { var f = evt.target.files[0]; var reader = new FileReader(); if (!f.type.match('image.*')) { alert("The selected file does not appear to be an image."); return; } reader.onload = function (e) { preview.attr('src', e.target.result); }; reader.readAsDataURL(f); //Show next upload-box $("#upload-box-" + nextNum).fadeIn(); }); }); </script> However, this code only first for the first time ... i.e. on selecting a file - It shows a preview and then shows the next "upload-box". However, when I browse using the second file it doesn't show any preview. From what I have ready, I need to close the Jquery function so that it can be initialised again but I am not sure how to do that. Any help will be grateful.

  • jQuery slideToggle - when div is toggled it pushes content out of viewable area (IE)

    - by Chris
    This is an annoying ocurrance in IE when I use the jQuery slideToggle effect. Without the div being open, page looks normal. The minute I toggle the div open, it extends past the current content, overtop of the footer, and out of the viewable browser area (Even after scrolling all the way down). This feature seems to work just fine in firefox. Do I need an additional hack or CSS to make it work in IE8?

    I just discovered the "box-sizing: border-box" css property which solves a bunch of cross browser layout problems for me. The only issue I now have is that ie7 doesn't seem to support it. Is there a hack to get ie7 to support it?

  • Java.lang.NullPointerException when using retreived Image (Unless method is used statically!)

    - by Emdiesse
    Hi there, This has been doing my head in all day and I have finally decided to resort to asking for help! In my MIDLet I have an instance of the java class ImageFetcher called anImg. Also within my MIDLet I have a command that simply say's fetch, a CommandListener that when detects fetch was clicked runs the function below. This function should simply run public getImage() from the anImg instance of class ImageFetcher which returns an image and then appends/sets this Image onto the form on the display. (You may recognise the getImage() function from the Nokia JavaME Wiki!!!) Instead of any image being displayed this is written to the output terminal in netbeans: Msg: Java.lang.NullPointerException HOWEVER, If I change public getImage() to public static getImage() and replace anImg.getImage() with ImageFetcher.getImage() the image is successfully displayed!!! Thank you for your replies on this issue :) I look forward to going my hair back after this ordeal! FetchImageApp.java ... ... ... private doThis(){ try { Image im; if ((im = anImg.getImage()) != null) { ImageItem ii = new ImageItem(null, im, ImageItem.LAYOUT_DEFAULT, null); // If there is already an image, set (replace) it if (form.size() != 0) { form.set(0, ii); } else // Append the image to the empty form { form.append(ii); } } else { form.append("Unsuccessful download."); } // Display the form with the image display.setCurrent(form); } catch (Exception e) { System.err.println("Msg: " + e.toString()); } } ... ... ... ImageFetcher.java ... ... ... /*-------------------------------------------------- * Open connection and download png into a byte array. *-------------------------------------------------*/ public Image getImage() throws IOException { String url = "http://kenai.com/attachments/wiki_images/chessgame/java-duke-logo.png"; ContentConnection connection = (ContentConnection) Connector.open(url); // * There is a bug in MIDP 1.0.3 in which read() sometimes returns // an invalid length. To work around this, I have changed the // stream to DataInputStream and called readFully() instead of read() // InputStream iStrm = connection.openInputStream(); DataInputStream iStrm = connection.openDataInputStream(); ByteArrayOutputStream bStrm = null; Image im = null; try { // ContentConnection includes a length method byte imageData[]; int length = (int) connection.getLength(); if (length != -1) { imageData = new byte[length]; // Read the png into an array // iStrm.read(imageData); iStrm.readFully(imageData); } else // Length not available... { bStrm = new ByteArrayOutputStream(); int ch; while ((ch = iStrm.read()) != -1) { bStrm.write(ch); } imageData = bStrm.toByteArray(); bStrm.close(); } // Create the image from the byte array im = Image.createImage(imageData, 0, imageData.length); } finally { // Clean up if (iStrm != null) { iStrm.close(); } if (connection != null) { connection.close(); } if (bStrm != null) { bStrm.close(); } } return (im == null ? null : im); } ... ... ...

  • Delete document with an empty ID

    - by Damien MATHIEU
    Hello, I have a CouchDB database in production. One of the documents has been edited (in Futon by an other developer). And it's lost it's ID (don't ask me how he did it). So now the document's id is an empty string, which makes it impossible to edit or delete via Futon. Is there a way I could hack into CouchDB to delete that document anyway ?

  • Displaying a component in EditorGridPanel without clicking

    - by Tower
    Hi, Is there a way to display a component in EditorGridPanel without the need to click on the cell? The problem I see on this demo is that the checkboxes are not Ext.form.Checkbox components, and not even inherited from it. The checkboxes are simply background images and since I am building a grid that needs ComboBoxes, it will not be simple to apply a similar hack.

  • How can I configure Devise for Ruby on Rails to store the emails and passwords somewhere other than in the user model?

    - by TLK
    I'd like to store emails in a separate table and allow users to save multiple emails and log in with any of them. I'd also like to store passwords in a different table. How can I configure Devise to store authentication info elsewhere? Worst case scenario, if I just have to hack into it, is there a generator to just port everything over to the app? I noticed there was a generator for the views. Thanks.
