  • My image is not showing in java, using ImageIcon

    - by user1048606
    I'd like to know why my images are now showing up when I use ImageIcon and when I have specified the directory the image is in. All I get is a black blank screen with nothing else on it. import java.awt.Image; import java.awt.event.KeyEvent; import javax.swing.ImageIcon; import java.awt.Image; import java.awt.event.KeyEvent; import java.util.ArrayList; import javax.swing.ImageIcon; // Class for handling key input public class Craft { private int dx; private int dy; private int x; private int y; private Image image; private Image image2; private ArrayList missiles; private final int CRAFT_SIZE = 20; private String craft = "C:\\Users\\Jimmy\\Desktop\\Jimmy's Folder\\programs\\craft.png"; public Craft() { ImageIcon ii = new ImageIcon(craft); image2 = ii.getImage(); missiles = new ArrayList(); x = 40; y = 60; } public void move() { x += dx; y += dy; } public int getX() { return x; } public int getY() { return y; } public Image getImage() { return image; } public ArrayList getMissiles() { return missiles; } public void keyPressed(KeyEvent e) { int key = e.getKeyCode(); // Shooting key if (key == KeyEvent.VK_SPACE) { fire(); } if (key == KeyEvent.VK_LEFT) { dx = -1; } if (key == KeyEvent.VK_RIGHT) { dx = 1; } if (key == KeyEvent.VK_UP) { dy = -1; } if (key == KeyEvent.VK_DOWN) { dy = 1; } } // Handles the missile object firing out of the ship public void fire() { missiles.add(new Missile(x + CRAFT_SIZE, y + CRAFT_SIZE/2)); } 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_UP) { dy = 0; } if (key == KeyEvent.VK_DOWN) { dy = 0; } } }

  • Using Three Flavors of LINQ To Populate a TreeView

    LINQ is a valuable technology. LINQ to XML, LINQ to Objects and LINQ to XSD, in particular, can save valuable time for developers and produce more maintainable code. Michael describes how he used three different flavours of LINQ to map XML to a Treeview component that he used in the QueryPicker control that was the subject of a two-part article here on Simple-Talk.

  • Using HTML entities in XML Literals (Avner Aharoni)

    One of the common use-cases of XML literals is creating HTML. However, HTML entities cannot be used in XML literals since LINQ to XML directly supports only the Data type definitions (DTD) defined in the XML 1.0 spec. You can read more about it here. The workaround is to use the Unicode representation of the entity, although its not as readable as the HTML entities, the output is the same. Here are two examples of HTML entities from the XHTML spec :   Entity...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Using Wordpress as a client to GeeksWithBlogs

    - by Malcolm Anderson
    I am really missing the tools in wordpress, that seem to be absent from GeeksWithBlogs [GWB].   The biggest two are being able to store drafts and being able to set a publish date.   I have done a little research on google I have not been able to find anyone saying that they have used Wordpress as a client for GWB, let alone a how-to.  Anyone got any clues or suggestions?

  • Capturing index operations using a DDL trigger

    - by AaronBertrand
    Today on twitter the following question came up on the #sqlhelp hash tag, from DaveH0ward : Is there a DMV that can tell me the last time an index was rebuilt? SQL 2008 My initial response: I don't believe so, you'd have to be monitoring for that ... perhaps a DDL trigger capturing ALTER_INDEX? Then I remembered that the default trace in SQL Server ( as long as it is enabled ) will capture these events. My follow-up response: You can get it from the default trace, blog post forthcoming So here is...(read more)

  • C#&ndash;Using a delegate to raise an event from one class to another

    - by Bill Osuch
    Even though this may be a relatively common task for many people, I’ve had to show it to enough new developers that I figured I’d immortalize it… MSDN says “Events enable a class or object to notify other classes or objects when something of interest occurs. The class that sends (or raises) the event is called the publisher and the classes that receive (or handle) the event are called subscribers.” Any time you add a button to a Windows Form or Web app, you can subscribe to the OnClick event, and you can also create your own event handlers to pass events between classes. Here I’ll show you how to raise an event from a separate class to a console application (or Windows Form). First, create a console app project (you could create a Windows Form, but this is easier for this demo). Add a class file called MyEvent.cs (it doesn’t really need to be a separate file, this is just for clarity) with the following code: public delegate void MyHandler1(object sender, MyEvent e); public class MyEvent : EventArgs {     public string message; } Your event can have whatever public properties you like; here we’re just got a single string. Next, add a class file called WorkerDLL.cs; this will simulate the class that would be doing all the work in the project. Add the following code: class WorkerDLL {     public event MyHandler1 Event1;     public WorkerDLL()     {     }     public void DoWork()     {         FireEvent("From Worker: Step 1");         FireEvent("From Worker: Step 5");         FireEvent("From Worker: Step 10");     }     private void FireEvent(string message)     {         MyEvent e1 = new MyEvent();         e1.message = message;         if (Event1 != null)         {             Event1(this, e1);         }         e1 = null;     } } Notice that the FireEvent method creates an instance of the MyEvent class and passes it to the Event1 handler (which we’ll create in just a second). Finally, add the following code to Program.cs: static void Main(string[] args) {     Program p = new Program(args); } public Program(string[] args) {     Console.WriteLine("From Console: Creating DLL");     WorkerDLL wd = new WorkerDLL();     Console.WriteLine("From Console: Wiring up event handler");     WireEventHandlers(wd);     Console.WriteLine("From Console: Doing the work");     wd.DoWork();     Console.WriteLine("From Console: Done - press any key to finish.");     Console.ReadLine(); } private void WireEventHandlers(WorkerDLL wd) {     MyHandler1 handler = new MyHandler1(OnHandler1);     wd.Event1 += handler; } public void OnHandler1(object sender, MyEvent e) {     Console.WriteLine(e.message); } The OnHandler1 method is called any time the event handler “hears” an event matching the specified signature – you could have it log to a file, write to a database, etc. Run the app in debug mode and you should see output like this: You can distinctly see which lines were written by the console application itself (Program.cs) and which were written by the worker class (WorkerDLL.cs).

  • Using normals in DirectX 10

    - by Dave
    I've got a working OBJ loader that loads vertices, indices, texture coordinates, and normals. As of right now it doesn't process texture coordinates or normals but it stores them in arrays and creates a valid mesh with the vertices and indices. Now I am trying to figure out how can I make the shader use the correct normal in the array for the current vertex if I can't setnormals() to my mesh. If I were to just use an index in my array of normals corresponding to the index in the vertices, how would I retrieve the current index the shader is processing? BTW: I am trying to write a blinn-phong shader technique. Also when I create the input layout and I've added the semantic NORMAL to it, how would I list the multiple semantics in that single parameter? Would I just separate it with a space? PS: If you need to see any code, just let me know.

  • Using VirtualBox to test drive Windows Blue

    - by Fat Bloke
    Oracle VM VirtualBox is great for trying out the latest and greatest technologies and platforms. So when Microsoft recently announced the Developer Preview for Windows Server 2012 R2 and Windows 8.1,  it was with eager anticipation that FatBloke ran to the TechNet Evaluation Center to download the isos. Once downloaded,  a new VM in VirtualBox Manager was created that used Windows 2012 (64-bit) OS type and all the defaults were selected. And on starting the VM, and pointing to the iso file to install from, the excitement rose as we saw a cool new splashscreen image: But suddenly our hopes are dashed.... It would seem that this platform requires an instruction (CMPXCHG16B) that VirtualBox doesn't offer "out-of-the-box".  Fear not, for the VirtualBox team knew that this day would finally arrive and have prepared an "in case of emergency" switch as follows: Power off the vm; At the command line type:  VBoxManage setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1 Start the VM and install Windows Server 2012 R2 This will be enabled by default in a future release, but geeks can't wait, hence this blog. Enjoy! -FB

  • Tips for managing internal and external links using WordPress [closed]

    - by keruilin
    So I'm looking for ways to optimize my site for user and search engine purposes. I've read several articles and looked at several different plugins. To say the least, I'm thoroughly confused as what are the best practices for managing internal and external links. Here is a list of some of my questions: Which internal links should be set to "nofollow"? Which external links should be set to "nofollow"? To what degree does actively managing links contribute to your PR? Should you use "nofollow" blindly on all links in comments? If a link to an external site is broken (404 or whatever), should you "nofollow" that link? What about "noindex"? As you can see, lots of questions. I'm hoping that you experienced webmasters can give a newb some best-practice advice.

  • 12.10 Unity doesn't appear when using Nvidia drivers

    - by Torben Gundtofte-Bruun
    I've just installed 12.10 from scratch. Unity also started okay, but in a poor resolution. I found a setting (I think it was in "software sources") to change the display driver to Nvidia, and then I rebooted. When Ubuntu now starts, it goes to the desktop (I see a file that I saved to the desktop) but there are no other screen elements -- no Unity, no menu bar at the top, no window decoration, nothing. Ctrl-Alt-T and Ctrl-Alt-F2 work as they should, but it's kinda limiting... How can I restore the default driver? I guess I need a way to open those "software sources" settings again - or anything else that could fix it! I hope I don't have to type all this by hand. How can I install a proper Nvidia driver so that I can get up to 1280x1024? My old tricks don't seem to work, but perhaps they might if I solve #1...

  • HTML5-Canvas: worth using ImpactJS or other framework?

    - by John
    I've been making an HTML5 game without any type of external framework. I haven't found a reason to use one so far. However, there is one thing I'm wondering about. On my Galaxy Nexus, I get about ~40fps. While that would usually be a decent framerate, my game is a rather fast paced game with a gamepad. Because of this, it feels very unsatisfying to play when not capped at 60fps. Are there frameworks out there that can improve performance without toning down on graphics? Or is there something I could do myself without necessarily having to use a framework? I've looked over the basic things such as sticking to integer coordinates, but I didn't see an increase in performance whatsoever? I did some testing with jsperf and results were virtually identical. Does this depend more on the browser?

  • Using Sizer for recording presentations

    - by John Paul Cook
    I needed to do some screen captures and recordings of SSMS and realized this is a common problem that many of you could use some help with. There is a freeware tool called Sizer (thanks to Paul Nielsen for telling me about it) that lets you chose your window size. I downloaded the zip file instead of the msi because I didn’t want to install anything. The extracted executable works perfectly as a portable application. After double-clicking the Sizer executable, an icon resembling a plus sign appears...(read more)

  • Using .add() on the same widget more than once

    - by Dillon Gilmore
    I asked this question on Reddit and was directed here. http://www.reddit.com/r/Ubuntu/comments/vhadl/quickly_dynamic_ui/ Unfortunately I am having the same issue and the problems seems that you can only use .add() on a widget once. So here is my code, self.ui.labels = [] for titles in entries: label = Gtk.Label() self.ui.labels.append(label) self.ui.viewport1.add(self.ui.labels[-1]) self.ui.paned1.show_all() Now, for fun I decided "What would happen if I just manually did..." self.ui.viewport1.add(Gtk.Label()) self.ui.viewport1.add(Gtk.Button()) self.ui.viewport1.add(Gtk.Entry()) For my first code snippet I get this error, Gtk-CRITICAL **: gtk_viewport_add: assertion gtk_bin_get_child (bin) == NULL' failed The error happens an unknown amount of times because the list entries can vary in length, but for my second code snippet it happens exactly twice. This means that when I viewport1.add() it works the first time, but all adds after that receive the error above. So my question, is there a way in python to use .add() on the same widget more than once?

  • My application quicklist goes missing when using "quickly submitubuntu"

    - by Kazade
    I'm trying to submit my app for the app showdown, but I've just noticed that when I use the "submitubuntu" Quickly command, my dynamic quicklist entries don't work. I think this is because the desktop file gets renamed from tickit.desktop to extras-tickit.desktop I'm coding a hacky fix to look for /usr/share/applications/extras-tickit.desktop and changing the argument for get_for_desktop_id() if it exists, but is there a better way? Can I stop Quickly renaming the desktop file?

  • Using box2d DrawDebugData with multi layer scene ?

    - by Mr.Gando
    In my Game, a Scene is composed by several layers. Each layer has different camera transformations. This way I can have a layer at z=3 (GUI), z=2 (Monsters), z=1 (scrolling background), and this 3 layers compose my whole Scene. My render loop looks something like: renderLayer() applyTransformations() renderVisibleEntities() renderChildLayers() end If I call DrawDebugData() in the render loop, the whole b2world debug data will be rendered once for each layer in my scene, this generates a mess, because the "debug boxes" get duplicated, some of them get the camera transformations applied and some of them don't, etc. What I would like to do, would be to make DrawDebugData to draw only certain debug boxes. In that way, I could call something like b2world->DrawDebugDataForLayer(int layer_id) and call that on each layer like : renderLayer() applyTransformations() renderVisibleEntities() //Only render my corresponding layer debug data b2world->DrawDebugDataForLayer(layer_id) renderChildLayers() end Is there a way to subclass b2World so I could add this functionality ( specific to my game ) ? If not, what would be the best way to achieve this (Cocos2d uses a similar scene graph approach and box2d, but I'm not sure if debugDraw works in Cocos2d... ) Thanks

  • Using Instance Nodes, worth it?

    - by Twitch
    I am making a 2d game where there are various environments with lots and lots of objects. There is a forest scene with like 1200 objects in total(trees mainly), of which around 100 are visible on the camera at any given time, as you move through the level. These are comprised of around 20 different kind of trees and other props. Each object is usually 2-6 triangles with a transparent texture. My developer asked me to replace each object in the scene with a node, and keeping only a minimal amount of actual objects which would be 300+ or so(?), since there are a few modified unique meshes. So he can instantiate the actual objects to keep the game light. Is this actually effective? And if so how much? I 've read about draw calls and such and I suppose that if I combine each texture (10 kinds of trees) in 1 mesh it will have the same effect?
