• Higher Performance With Spritesheets Than With Rotating Using C# and XNA 4.0?

  - by Manuel Maier

  I would like to know what the performance difference is between using multiple sprites in one file (sprite sheets) to draw a game-character being able to face in 4 directions and using one sprite per file but rotating that character to my needs. I am aware that the sprite sheet method restricts the character to only be able to look into predefined directions, whereas the rotation method would give the character the freedom of "looking everywhere". Here's an example of what I am doing: Single Sprite Method Assuming I have a 64x64 texture that points north. So I do the following if I wanted it to point east: spriteBatch.Draw( _sampleTexture, new Rectangle(200, 100, 64, 64), null, Color.White, (float)(Math.PI / 2), Vector2.Zero, SpriteEffects.None, 0); Multiple Sprite Method Now I got a sprite sheet (128x128) where the top-left 64x64 section contains a sprite pointing north, top-right 64x64 section points east, and so forth. And to make it point east, i do the following: spriteBatch.Draw( _sampleSpritesheet, new Rectangle(400, 100, 64, 64), new Rectangle(64, 0, 64, 64), Color.White); So which of these methods is using less CPU-time and what are the pro's and con's? Is .NET/XNA optimizing this in any way (e.g. it notices that the same call was done last frame and then just uses an already rendered/rotated image thats still in memory)?

• Why do I get a blinking screen when running lwjgl?

  - by SystemNetworks

  I didn't have any errors. But When I run my lwjgl game, it gives me a blinking screen. Here is the code: package L1F3; import org.lwjgl.opengl.Display; import org.lwjgl.opengl.DisplayMode; import org.lwjgl.LWJGLException; import static org.lwjgl.opengl.GL11.*; public class Main { public static void main(String[] args) { try { Display.setDisplayMode(new DisplayMode(640, 480)); Display.setTitle("A fresh display!"); Display.create(); } catch (LWJGLException e) { e.printStackTrace(); Display.destroy(); System.exit(1); } while(!Display.isCloseRequested()) { Display.update(); } Display.destroy(); System.exit(0); } } How do I stop the blinking screen? I was thinking its my framerate. I deleted Display.sync but it still gives me all white and black. Last time it didn't give me a blinking screen. EDIT When I remove Display.update() , it gives me a perfect screen, no blinking or no white. Will my game work without it? I can also close it perfectly.

• Recommended display/background brightness ratio and UI color schemes [duplicate]

  - by user1306322

  This question already has an answer here: Colour scheme for editor - guidelines or medical reccomendations 3 answers I'm a professional programmer, which means I spend a lot of time staring at various displays. Recently I've been having some problems with my eyes, so I went to talk to several doctors, which all gave me different recommendations as to how bright the background of the room should be in comparison to the display's brightness. It was very confusing, as some of them even agreed with counter-arguments of others, which made it all even less clear. So I'd like to ask the professional programmers, as people who actually have some experience with that. Some of the doctors said that looking at a monitor is like looking at a book, so the brightness ratios should be approximately the same. Others said that background should be as bright as the display itself, because then there is no brightness difference at the edges, and that's what may cause eye fatigue. From my own experience, I can say that reading a book isn't the same as writing or debugging a program, where you have to pay close attention to each symbol, and in books most words are easily recognizable without focusing too hard on them. Also, books are black on white and I myself use the default (dark text, white bg) color scheme for my IDE, but I've seen some programmers use mid-bright text on very dark background color schemes. So I'd like to ask what are the recommended display/background brightness ratios for programming? I'm not sure this site is the right one for this kind of questions, so if you know a better one, please comment.

• b43 Firmware Error when trying to install Ubuuntu 14.04 on XP Laptop

  - by WizardNo.7

  I know I'm an Ubuntu and Linux n00b, but I've been browsing the web for a few days searching for a solution, and none of the other b43 posts etc solve my problem. I am trying to install Ubuntu 14.04 on a Fujitsu Siemens Amilo Pro laptop(It's quite old yes, has about 30GB Hard Drive and I think 192mb of RAM) which currently has Windows XP installed(which I'd like to keep for the time being). I have downloaded the 32-bit Desktop ISO and used unetbootin to create a Live USB for this laptop. When I boot from USB, I arrive at the unetbootin Grey and Blue menu and pick either "Try Ubuntu without installing", or "Install Ubuntu". The menu goes away and an Ubuntu loadscreen showing UBUNTU and four dots which progressively change between white and orange. At about the second color changing cycle a white underscore symbol appears next to the fourth dot and flickers, and then I get the usual: [ 95.514833] b43-phy0 ERROR: Firmware file "b43/ucode5.fw" not found [ 95.514847] b43-phy0 ERROR: Firmware file "b43-open/ucode5.fw" not found [ 95.514855] b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all the instruction on this website. After this I have to hard reboot or shut-down. I don't have a previous Linux install so cannot do the apt-get from my previous install. I cannot access the boot options menu by using F6 or similar. Any ideas? Thanks beforehand!

• Mouse pointer size inconsistent

  - by charon00

  Since installing Ubuntu 12.04, I've been having a problem with the mouse pointer size. On the desktop, it is quite a bit larger than it should be (24), though the different cursors (editing text, hyperlink hand, etc) are correct. The size changes to the correct size when the pointer is over some application windows (GVim, Netbeans, Firefox), but then changes back once it is moved out of the window. There was a similar question here, but the Xdefaults solution did not work for me, and I didn't want to try the one requiring editing the icon image. In addition, I've tried changing the cursor theme using sudo update-alternatives --config x-cursor-theme as well as using the dconf-editor, but though I can change the theme, the size issue remains. In case it's relevant, I'm running on a dual-screen setup with monitor sizes of 2560x1600 and 1920x1080, using the NVidia video driver. Is there another way to control pointer size, or a setting that might be messing it up? EDIT: These are the values/options I have for update-alternatives and in dconf-editor. I'm now wondering if Netbeans and Firefox are making the mouse pointer smaller than it should be, but I'm not sure how big 24 should be... update-alternatives: Selection Path Priority Status ------------------------------------------------------------ 0 /usr/share/icons/DMZ-White/cursor.theme 90 auto mode 1 /etc/X11/cursors/core.theme 30 manual mode 2 /etc/X11/cursors/handhelds.theme 20 manual mode 3 /etc/X11/cursors/redglass.theme 20 manual mode 4 /etc/X11/cursors/whiteglass.theme 20 manual mode * 5 /usr/share/icons/DMZ-Black/cursor.theme 30 manual mode 6 /usr/share/icons/DMZ-White/cursor.theme 90 manual mode dconf-editor: I can't post the image since I'm a new user but the cursor-size is set to 24 and the cursor-theme is DMZ-Black.

• [WPF] ComboBox Style problems with DisplayMemberPath

  - by kornelijepetak

  I have a ComboBox and I have set the combo.ItemsSource property to a List object. The Book class contains two properties: "Abbreviation" and "Name". I have set the ComboBox's DisplayMemberPath to "Abbreviation" but the following style that is set on the ComboBox does not display the Abbreviation property, but instead shows "Words.Book" which is the name of the class. The ComboBox drop-down displays a list correctly (Using the specified Abbreviation property). The problem is in the selected ComboBox item, the one displayed when the ComboBox' drop-down is closed. I guess the problem is in ContentPresenter in DataTemplate but I was unable to find a successful solution. Currently the ContentPresenter's Content property is set to Content="{TemplateBinding Content} but I don't know if that's how it should be. Any ideas how to show the property specified in DisplayMemberPath on the selected item?

• li element background colors and overflow scrolling

  - by user17753

  I created a simple html source, and applied a small CSS style sheet to it: html { width: 100%; } body { font-family: Calibri, Tahoma, Geneva, sans-serif; padding: 20px; } pre { padding: 0; margin: 0 auto; border: 1px solid #888; font-family: Menlo,Monaco,Consolas,monospace; color: #000; width: 80%; overflow: auto; } pre li { white-space: pre; } ol { margin-top: 0; margin-bottom: 0; /* IE indents via margin-left */ color: #979797; background: #E3E3E3; } .li1 { background: #F5F5F5 } .li2 { background: #eee } I have an ordered list inside a pre-formatted tag. Every other list element is either given the class attribute li1 or li2 (the purpose of which is to alternate the colors). The list elements need the white-space: pre because the white space before and after the text node is important. The pre is to be 80% of the containing element (which ends up being 80% of the window's width). In the event of overflow in the x dimension, I want scrolling. I did all this in the above CSS, and it almost works. The issue I am having is that the background colors of the list elements don't extend with the content. They seem to be capped to the original width of the pre and/or ol element as demonstrated in the following picture where I scroll all the way right as possible: I tinkered with the CSS for a while, but I cannot determine the root cause for this or the fix. Looking for some advice on this one, thanks. Complete source with the issue is as below, NOTE: to would-be editors of the below code the pre element is intended to be on a single line as it's pre-formatted text, and formatting it otherwise would change things. <!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <title>Test Site</title> <style type="text/css"> html { width: 100%; } body { font-family: Calibri, Tahoma, Geneva, sans-serif; padding: 20px; } pre { padding: 0; margin: 0 auto; border: 1px solid #888; font-family: Menlo,Monaco,Consolas,monospace; color: #000; width: 80%; overflow: auto; } pre li { white-space: pre; } ol { margin-top: 0; margin-bottom: 0; /* IE indents via margin-left */ color: #979797; background: #E3E3E3; } .li1 { background: #F5F5F5 } .li2 { background: #eee } </style> </head> <body> <pre class="php"><ol><li class="li1">pre a &#123; text-decoration: none &#125;</li><li class="li2">pre a:hover &#123; background: #C8C8C8 }</li><li class="li1">pre li &#123; white-space: pre; &#125;</li><li class="li2">&nbsp;</li><li class="li1">.php ol &#123; margin-top: 0; margin-bottom: 0; /* IE indents via margin-left */</li><li class="li2"> color: #979797; background: #E3E3E3; }</li><li class="li1">&nbsp;</li><li class="li2">&nbsp;</li><li class="li1">&nbsp;</li><li class="li2">.php .li1 &#123; background: #F5F5F5 }</li><li class="li1">.php .li2 &#123; background: #eee }</li><li class="li2">&nbsp;</li><li class="li1">&nbsp;</li><li class="li2">.php .st0 &#123; color: #C0C } /* string content */</li><li class="li1">.php .st_h &#123; color: #F0C } /* string content single quoted */</li><li class="li2">.php .sy0 &#123; color: #000 } /* semi-colon, operators */ </li><li class="li1">.php .br0 &#123; color: #000 } /* parens */</li><li class="li2">.php .kw2 &#123; color: #00F } /* php tags */</li><li class="li1">.php .sy1 &#123; color: #00F } /* php tags */</li><li class="li2">.php .nu0 &#123; color: #F00 } /* numbers */</li><li class="li1">.php .kw3 &#123; color: #096 } /* core language functions */</li><li class="li2">.php .re0 &#123; color: #09F; font-weight: bold; } /* variables */</li><li class="li1">.php .kw1 &#123; color: #069; font-weight: bold; } /* control statements? */</li><li class="li2">.php .kw4 &#123; color: #069; font-weight: bold; } /* bool? */</li><li class="li1">.php .co1 &#123; color: #FF8400 } /* Forward slash comments */</li></ol></pre> </body> </html>

• WPF, how can I optimize lines and circles drawing ?

  - by Aurélien Ribon

  Hello ! I am developping an application where I need to draw a graph on the screen. For this purpose, I use a Canvas and I put Controls on it. An example of such a draw as shown in the app can be found here : http://free0.hiboox.com/images/1610/d82e0b7cc3521071ede601d3542c7bc5.png It works fine for simple graphs, but I also want to be able to draw very large graphs (hundreds of nodes). And when I try to draw a very large graph, it takes a LOT of time to render. My problem is that the code is not optimized at all, I just wanted it to work. Until now, I have a Canvas on the one hand, and multiple Controls on the other hands. Actually, circles and lines are listed in collections, and for each item of these collections, I use a ControlTemplate, defining a red circle, a black circle, a line, etc. Here is an example, the definition of a graph circle : <!-- STYLE : DISPLAY DATA NODE --> <Style TargetType="{x:Type flow.elements:DisplayNode}"> <Setter Property="Canvas.Left" Value="{Binding X, RelativeSource={RelativeSource Self}}" /> <Setter Property="Canvas.Top" Value="{Binding Y, RelativeSource={RelativeSource Self}}" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type flow.elements:DisplayNode}"> <!--TEMPLATE--> <Grid x:Name="grid" Margin="-30,-30,0,0"> <Ellipse x:Name="selectionEllipse" StrokeThickness="0" Width="60" Height="60" Opacity="0" IsHitTestVisible="False"> <Ellipse.Fill> <RadialGradientBrush> <GradientStop Color="Black" Offset="0.398" /> <GradientStop Offset="1" /> </RadialGradientBrush> </Ellipse.Fill> </Ellipse> <Ellipse Stroke="Black" Width="30" Height="30" x:Name="ellipse"> <Ellipse.Fill> <LinearGradientBrush EndPoint="0,1"> <GradientStop Offset="0" Color="White" /> <GradientStop Offset="1.5" Color="LightGray" /> </LinearGradientBrush> </Ellipse.Fill> </Ellipse> <TextBlock x:Name="tblock" Text="{Binding NodeName, RelativeSource={RelativeSource Mode=TemplatedParent}}" Foreground="Black" VerticalAlignment="Center" HorizontalAlignment="Center" FontSize="10.667" /> </Grid> <!--TRIGGERS--> <ControlTemplate.Triggers> <!--DATAINPUT--> <MultiTrigger> <MultiTrigger.Conditions> <Condition Property="SkinMode" Value="NODETYPE" /> <Condition Property="NodeType" Value="DATAINPUT" /> </MultiTrigger.Conditions> <Setter TargetName="tblock" Property="Foreground" Value="White" /> <Setter TargetName="ellipse" Property="Fill"> <Setter.Value> <LinearGradientBrush EndPoint="0,1"> <GradientStop Offset="-0.5" Color="White" /> <GradientStop Offset="1" Color="Black" /> </LinearGradientBrush> </Setter.Value> </Setter> </MultiTrigger> <!--DATAOUTPUT--> <MultiTrigger> <MultiTrigger.Conditions> <Condition Property="SkinMode" Value="NODETYPE" /> <Condition Property="NodeType" Value="DATAOUTPUT" /> </MultiTrigger.Conditions> <Setter TargetName="tblock" Property="Foreground" Value="White" /> <Setter TargetName="ellipse" Property="Fill"> <Setter.Value> <LinearGradientBrush EndPoint="0,1"> <GradientStop Offset="-0.5" Color="White" /> <GradientStop Offset="1" Color="Black" /> </LinearGradientBrush> </Setter.Value> </Setter> </MultiTrigger> ....... THERE IS A TOTAL OF 7 MULTITRIGGERS ....... </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> Also, the lines are drawn using the Line Control. <!-- STYLE : DISPLAY LINK --> <Style TargetType="{x:Type flow.elements:DisplayLink}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type flow.elements:DisplayLink}"> <!--TEMPLATE--> <Line X1="{Binding X1, RelativeSource={RelativeSource TemplatedParent}}" X2="{Binding X2, RelativeSource={RelativeSource TemplatedParent}}" Y1="{Binding Y1, RelativeSource={RelativeSource TemplatedParent}}" Y2="{Binding Y2, RelativeSource={RelativeSource TemplatedParent}}" Stroke="Gray" StrokeThickness="2" x:Name="line" /> <!--TRIGGERS--> <ControlTemplate.Triggers> <!--BRANCH : ASSERTION--> <MultiTrigger> <MultiTrigger.Conditions> <Condition Property="SkinMode" Value="BRANCHTYPE" /> <Condition Property="BranchType" Value="ASSERTION" /> </MultiTrigger.Conditions> <Setter TargetName="line" Property="Stroke" Value="#E0E0E0" /> </MultiTrigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> So, I need your advices. How can I drastically improve the rendering performances ? Should I define each MultiTrigger circle rendering possibility in its own ControlTemplate instead ? Is there a better line drawing technique ? Should I open a DrawingContext and draw everything in one control, instead of having hundreds of controls ?

• Twitter Bootstrap styling conflicts with plug-ins like jqGrid and other third part libraries

  - by Renso

  Issues:The concern is that the Twitter Bootstrap framework is that some of their css selectors are simply too generic and have incompatibility issues and conflicts with most third party plug-ins and css libraries, like jQuery-UI and jqGrid.My most pressing concern is only with the generic selector for the styling of "INPUT" controls.Some concerns:So basically anyone using BS (Bootstrap) will have to override styling 100% of the time on all input controls on all their web pages for all the plug-ins they use that render their own styling for input controls. This seems to chisel away any reason for using Bootstrap. Overriding Bootstrap css in this case seems illogical at best as it implies the BS styling is not correct or as granular as it is supposed to be. It also suggests you realize there is an issue here. Any person who has written a fair amount of css will realize that it is a mammoth task to to take an existing app, converting it to BS and then having to find all non-BS input controls and styling them all. The worst part is that there is no generic styling for this as each input control has a different source/context, some are regular tags and some belong to plug-ins, each with their own flavor of styling. For new web apps the challenge is not that different, each time you add a new plug-in you will have to test all facets of it, and I mean all of it, pop-ups, etc, that contain any kind of input control to make sure it is styled correctly. I am having a hard time seeing the benefits of BS in this context. So until the BS team addresses the issue, or not, you may be wondering what is the easiest solution.Help the community to drive this issue home by creating a new issue on github, see my entry here: https://github.com/twitter/bootstrap/issues/4008. As you can see I got some good and some negative feedback, but we all agree it is an issue. I do believe my solution below should be reverse compatible if the proper class declarations were followed as recommended by Bootstrap.The solution:Add a higher-level qualifier to the input selector, which may not break anything.  Add "control-group" and "controls" classes as higher-level selectors, as they have to be declared inside those classes anyway as far as I understand the design approach of BS. So in my example below can modify the css without possible breaking anything, see the css at the bottom. I tested this briefly and seems to render just as expected. May not be complete as I only spent a few minutes on the css. Your feedback will be greatly appreciated. <div class="control-group">    <label title="" for="Contact_FirstName" class="control-label">First Name</label>    <div class="controls">        <input type="text" value="" name="Contact.FirstName" id="Contact_FirstName" data-val-required="The Reader Contact&amp;#39;s First Name is required" data-val-length-min="2" data-val-length-max="250" data-val-length="The maximum length allowed for the Reader Contact&amp;#39;s First Name is 250 characters and must be two or more characters long" data-val="true" class="input-medium">        <span data-valmsg-replace="true" data-valmsg-for="Contact.FirstName" class="field-validation-valid"></span>    </div></div>Here are the SCSS (SASS) updates. In stead of just including the updates I decided to include the entire bootstrap SCSS file so you can just copy-and-paste it in stead of trying to figure out what selectors have changed./*! *

• Strange WPF ListBox Behavior

  - by uncle-harvey

  I’m trying to bind a List of items to a listbox in WPF. The items are grouped by one value and each group is to be housed in an expander. Everything works fine when I don’t use any custom styles. However, when I use custom styles (which work properly with non-grouped items and as independent controls) the binding doesn’t display any items. Below is the code I’m executing. Any ideas why the items won’t show up in the Expander? Test.xaml: <Window x:Class="Glossy.Test" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Test" Height="300" Width="300">

• [Windows 8] Update TextBox’s binding on TextChanged

  - by Benjamin Roux

  Since UpdateSourceTrigger is not available in WinRT we cannot update the text’s binding of a TextBox at will (or at least not easily) especially when using MVVM (I surely don’t want to write behind-code to do that in each of my apps !). Since this kind of demand is frequent (for example to disable of button if the TextBox is empty) I decided to create some attached properties to to simulate this missing behavior. namespace Indeed.Controls { public static class TextBoxEx { public static string GetRealTimeText(TextBox obj) { return (string)obj.GetValue(RealTimeTextProperty); } public static void SetRealTimeText(TextBox obj, string value) { obj.SetValue(RealTimeTextProperty, value); } public static readonly DependencyProperty RealTimeTextProperty = DependencyProperty.RegisterAttached("RealTimeText", typeof(string), typeof(TextBoxEx), null); public static bool GetIsAutoUpdate(TextBox obj) { return (bool)obj.GetValue(IsAutoUpdateProperty); } public static void SetIsAutoUpdate(TextBox obj, bool value) { obj.SetValue(IsAutoUpdateProperty, value); } public static readonly DependencyProperty IsAutoUpdateProperty = DependencyProperty.RegisterAttached("IsAutoUpdate", typeof(bool), typeof(TextBoxEx), new PropertyMetadata(false, OnIsAutoUpdateChanged)); private static void OnIsAutoUpdateChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e) { var value = (bool)e.NewValue; var textbox = (TextBox)sender; if (value) { Observable.FromEventPattern<TextChangedEventHandler, TextChangedEventArgs>( o => textbox.TextChanged += o, o => textbox.TextChanged -= o) .Do(_ => textbox.SetValue(TextBoxEx.RealTimeTextProperty, textbox.Text)) .Subscribe(); } } } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The code is composed of two attached properties. The first one “RealTimeText” reflects the text in real time (updated after each TextChanged event). The second one is only used to enable the functionality. To subscribe to the TextChanged event I used Reactive Extensions (Rx-Metro package in Nuget). If you’re not familiar with this framework just replace the code with a simple: textbox.TextChanged += textbox.SetValue(TextBoxEx.RealTimeTextProperty, textbox.Text); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } To use these attached properties, it’s fairly simple <TextBox Text="{Binding Path=MyProperty, Mode=TwoWay}" ic:TextBoxEx.IsAutoUpdate="True" ic:TextBoxEx.RealTimeText="{Binding Path=MyProperty, Mode=TwoWay}" /> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Just make sure to create a binding (in TwoWay) for both Text and RealTimeText. Hope this helps !

• Changing enum in a different class for screen

  - by user2434321

  I'm trying to make a start menu for my game and my code uses Enum's to moniter the screen state. Now i want to change the screenstate declared in the main class, in my Background class Screen screen = new Screen(); is declared in the Game1 class Background(ref screen); This is in the update method for the Background Class KeyboardState keystate = Keyboard.GetState(); switch (screen) { case Screen.Start: if (isPressed && keystate.IsKeyUp(Keys.Up) && keystate.IsKeyUp(Keys.Down) && keystate.IsKeyUp(Keys.Enter)) { isPressed = false; } if (keystate.IsKeyDown(Keys.Down) && isPressed != true) { if (menuState == MenuState.Options) menuState = MenuState.Credits; if (menuState == MenuState.Play) menuState = MenuState.Options; isPressed = true; } if (keystate.IsKeyDown(Keys.Up) && isPressed != true) { if (menuState == MenuState.Options) menuState = MenuState.Play; if (menuState == MenuState.Credits) menuState = MenuState.Options; isPressed = true; } switch (menuState) { case MenuState.Play: arrowRect.X = 450; arrowRect.Y = 220; if (keystate.IsKeyDown(Keys.Enter) && isPressed != true) screen = Screen.Play; break; case MenuState.Options: arrowRect.X = 419; arrowRect.Y = 340; if (keystate.IsKeyDown(Keys.Enter) && isPressed != true) screen = Screen.Options; break; case MenuState.Credits: arrowRect.X = 425; arrowRect.Y = 460; if (keystate.IsKeyDown(Keys.Enter) && isPressed != true) screen = Screen.Credits; break; } break; } } For some reason when I play this and I hit the enter button the Background class's screen is changed but the main class's screen isn't how can i change this? EDIT 1* class Background { private Texture2D background; private Rectangle backgroundRect; private Texture2D arrow; private Rectangle arrowRect; private Screen screen; private MenuState menuState; private bool isPressed = false; public Screen getScreenState(ref Screen screen) { this.screen = screen; return this.screen; } public Background(ref Screen screen) { this.screen = screen; } public void Update() { KeyboardState keystate = Keyboard.GetState(); switch (screen) { case Screen.Start: if (isPressed && keystate.IsKeyUp(Keys.Up) && keystate.IsKeyUp(Keys.Down) && keystate.IsKeyUp(Keys.Enter)) { isPressed = false; } if (keystate.IsKeyDown(Keys.Down) && isPressed != true) { if (menuState == MenuState.Options) menuState = MenuState.Credits; if (menuState == MenuState.Play) menuState = MenuState.Options; isPressed = true; } if (keystate.IsKeyDown(Keys.Up) && isPressed != true) { if (menuState == MenuState.Options) menuState = MenuState.Play; if (menuState == MenuState.Credits) menuState = MenuState.Options; isPressed = true; } switch (menuState) { case MenuState.Play: arrowRect.X = 450; arrowRect.Y = 220; if (keystate.IsKeyDown(Keys.Enter) && isPressed != true) screen = Screen.Play; break; case MenuState.Options: arrowRect.X = 419; arrowRect.Y = 340; if (keystate.IsKeyDown(Keys.Enter) && isPressed != true) screen = Screen.Options; break; case MenuState.Credits: arrowRect.X = 425; arrowRect.Y = 460; if (keystate.IsKeyDown(Keys.Enter) && isPressed != true) screen = Screen.Credits; break; } break; case Screen.Pause: break; case Screen.Over: break; } } public void LoadStartContent(ContentManager Content, GraphicsDeviceManager graphics) { background = Content.Load<Texture2D>("startBackground"); arrow = Content.Load<Texture2D>("arrow"); backgroundRect = new Rectangle(0, 0, graphics.GraphicsDevice.Viewport.Width, graphics.GraphicsDevice.Viewport.Height); arrowRect = new Rectangle(450, 225, arrow.Width, arrow.Height); screen = Screen.Start; } public void LoadPlayContent(ContentManager Content, GraphicsDeviceManager graphics) { background = Content.Load<Texture2D>("Background"); backgroundRect = new Rectangle(0, 0, graphics.GraphicsDevice.Viewport.Width, graphics.GraphicsDevice.Viewport.Height); screen = Screen.Play; } public void LoadOverContent(ContentManager Content, GraphicsDeviceManager graphics) { } public void Draw(SpriteBatch spritebatch) { if (screen == Screen.Start) { spritebatch.Draw(background, backgroundRect, Color.White); spritebatch.Draw(arrow, arrowRect, Color.White); } else spritebatch.Draw(background, backgroundRect, Color.White); } } Thats my background class!

• [Windows 8] Application bar popup button

  - by Benjamin Roux

  Here is a small control to create an application bar button which will display a content in a popup when the button is clicked. Visually it gives this So how to create this? First you have to use the AppBarPopupButton control below.   namespace Indeed.Controls { public class AppBarPopupButton : Button { public FrameworkElement PopupContent { get { return (FrameworkElement)GetValue(PopupContentProperty); } set { SetValue(PopupContentProperty, value); } } public static readonly DependencyProperty PopupContentProperty = DependencyProperty.Register("PopupContent", typeof(FrameworkElement), typeof(AppBarPopupButton), new PropertyMetadata(null, (o, e) => (o as AppBarPopupButton).CreatePopup())); private Popup popup; private SerialDisposable sizeChanged = new SerialDisposable(); protected override void OnTapped(Windows.UI.Xaml.Input.TappedRoutedEventArgs e) { base.OnTapped(e); if (popup != null) { var transform = this.TransformToVisual(Window.Current.Content); var offset = transform.TransformPoint(default(Point)); sizeChanged.Disposable = PopupContent.ObserveSizeChanged().Do(_ => popup.VerticalOffset = offset.Y - (PopupContent.ActualHeight + 20)).Subscribe(); popup.HorizontalOffset = offset.X + 24; popup.DataContext = this.DataContext; popup.IsOpen = true; } } private void CreatePopup() { popup = new Popup { IsLightDismissEnabled = true }; popup.Closed += (o, e) => this.GetParentOfType<AppBar>().IsOpen = false; popup.ChildTransitions = new Windows.UI.Xaml.Media.Animation.TransitionCollection(); popup.ChildTransitions.Add(new Windows.UI.Xaml.Media.Animation.PopupThemeTransition()); var container = new Grid(); container.Children.Add(PopupContent); popup.Child = container; } } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The ObserveSizeChanged method is just an extension method which observe the SizeChanged event (using Reactive Extensions - Rx-Metro package in Nuget). If you’re not familiar with Rx, you can replace this line (and the SerialDisposable stuff) by a simple subscription to the SizeChanged event (using +=) but don’t forget to unsubscribe to it ! public static IObservable<Unit> ObserveSizeChanged(this FrameworkElement element) { return Observable.FromEventPattern<SizeChangedEventHandler, SizeChangedEventArgs>( o => element.SizeChanged += o, o => element.SizeChanged -= o) .Select(_ => Unit.Default); } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The GetParentOfType extension method just retrieve the first parent of type (it’s a common extension method that every Windows 8 developer should have created !). You can of course tweak to control (for example if you want to center the content to the button or anything else) to fit your needs. How to use this control? It’s very simple, in an AppBar control just add it and define the PopupContent property. <ic:AppBarPopupButton Style="{StaticResource RefreshAppBarButtonStyle}" HorizontalAlignment="Left"> <ic:AppBarPopupButton.PopupContent> <Grid> [...] </Grid> </ic:AppBarPopupButton.PopupContent> </ic:AppBarPopupButton> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } When the button is clicked the popup is displayed. When the popup is closed, the app bar is closed too. I hope this will help you !

• Doing unit and integration tests with the Web API HttpClient

  One of the nice things about the new HttpClient in System.Net.Http is the support for mocking responses or handling requests in a http server hosted in-memory. While the first option is useful for scenarios in which we want to test our client code in isolation (unit tests for example), the second one enables more complete integration testing scenarios that could include some more components in the stack such as model binders or message handlers for example.   The HttpClient can receive a HttpMessageHandler as argument in one of its constructors. public class HttpClient : HttpMessageInvoker { public HttpClient(); public HttpClient(HttpMessageHandler handler); public HttpClient(HttpMessageHandler handler, bool disposeHandler); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } For the first scenario, you can create a new HttpMessageHandler that fakes the response, which you can use in your unit test. The only requirement is that you somehow inject an HttpClient with this custom handler in the client code. public class FakeHttpMessageHandler : HttpMessageHandler { HttpResponseMessage response; public FakeHttpMessageHandler(HttpResponseMessage response) { this.response = response; } protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, System.Threading.CancellationToken cancellationToken) { var tcs = new TaskCompletionSource<HttpResponseMessage>(); tcs.SetResult(response); return tcs.Task; } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } In an unit test, you can do something like this. var fakeResponse = new HttpResponse(); var fakeHandler = new FakeHttpMessageHandler(fakeResponse); var httpClient = new HttpClient(fakeHandler); var customerService = new CustomerService(httpClient); // Do something // Asserts .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } CustomerService in this case is the class under test, and the one that receives an HttpClient initialized with our fake handler. For the second scenario in integration tests, there is a In-Memory host “System.Web.Http.HttpServer” that also derives from HttpMessageHandler and you can use with a HttpClient instance in your test. This has been discussed already in these two great posts from Pedro and Filip.

• Flood fill algorithm for Game of Go

  - by Jackson Borghi

  I'm having a hell of a time trying to figure out how to make captured stones disappear. I've read everywhere that I should use the flood fill algorithm, but I haven't had any luck with that so far. Any help would be amazing! Here is my code: package Go; import static java.lang.Math.*; import static stdlib.StdDraw.*; import java.awt.Color; public class Go2 { public static Color opposite(Color player) { if (player == WHITE) { return BLACK; } return WHITE; } public static void drawGame(Color[][] board) { Color[][][] unit = new Color[400][19][19]; for (int h = 0; h < 400; h++) { for (int x = 0; x < 19; x++) { for (int y = 0; y < 19; y++) { unit[h][x][y] = YELLOW; } } } setXscale(0, 19); setYscale(0, 19); clear(YELLOW); setPenColor(BLACK); line(0, 0, 0, 19); line(19, 19, 19, 0); line(0, 19, 19, 19); line(0, 0, 19, 0); for (double i = 0; i < 19; i++) { line(0.0, i, 19, i); line(i, 0.0, i, 19); } for (int x = 0; x < 19; x++) { for (int y = 0; y < 19; y++) { if (board[x][y] != YELLOW) { setPenColor(board[x][y]); filledCircle(x, y, 0.47); setPenColor(GRAY); circle(x, y, 0.47); } } } int h = 0; } public static void main(String[] args) { int px; int py; Color[][] temp = new Color[19][19]; Color[][] board = new Color[19][19]; Color player = WHITE; for (int i = 0; i < 19; i++) { for (int h = 0; h < 19; h++) { board[i][h] = YELLOW; temp[i][h] = YELLOW; } } while (true) { drawGame(board); while (!mousePressed()) { } px = (int) round(mouseX()); py = (int) round(mouseY()); board[px][py] = player; while (mousePressed()) { } floodFill(px, py, player, board, temp); System.out.print("XXXXX = "+ temp[px][py]); if (checkTemp(temp, board, px, py)) { for (int x = 0; x < 19; x++) { for (int y = 0; y < 19; y++) { if (temp[x][y] == GRAY) { board[x][y] = YELLOW; } } } } player = opposite(player); } } private static boolean checkTemp(Color[][] temp, Color[][] board, int x, int y) { if (x < 19 && x > -1 && y < 19 && y > -1) { if (temp[x + 1][y] == YELLOW || temp[x - 1][y] == YELLOW || temp[x][y - 1] == YELLOW || temp[x][y + 1] == YELLOW) { return false; } } if (x == 18) { if (temp[x - 1][y] == YELLOW || temp[x][y - 1] == YELLOW || temp[x][y + 1] == YELLOW) { return false; } } if (y == 18) { if (temp[x + 1][y] == YELLOW || temp[x - 1][y] == YELLOW || temp[x][y - 1] == YELLOW) { return false; } } if (y == 0) { if (temp[x + 1][y] == YELLOW || temp[x - 1][y] == YELLOW || temp[x][y + 1] == YELLOW) { return false; } } if (x == 0) { if (temp[x + 1][y] == YELLOW || temp[x][y - 1] == YELLOW || temp[x][y + 1] == YELLOW) { return false; } } else { if (x < 19) { if (temp[x + 1][y] == GRAY) { checkTemp(temp, board, x + 1, y); } } if (x >= 0) { if (temp[x - 1][y] == GRAY) { checkTemp(temp, board, x - 1, y); } } if (y < 19) { if (temp[x][y + 1] == GRAY) { checkTemp(temp, board, x, y + 1); } } if (y >= 0) { if (temp[x][y - 1] == GRAY) { checkTemp(temp, board, x, y - 1); } } } return true; } private static void floodFill(int x, int y, Color player, Color[][] board, Color[][] temp) { if (board[x][y] != player) { return; } else { temp[x][y] = GRAY; System.out.println("x = " + x + " y = " + y); if (x < 19) { floodFill(x + 1, y, player, board, temp); } if (x >= 0) { floodFill(x - 1, y, player, board, temp); } if (y < 19) { floodFill(x, y + 1, player, board, temp); } if (y >= 0) { floodFill(x, y - 1, player, board, temp); } } } }

• Populate a WCF syndication podcast using MP3 ID3 metadata tags

  - by brian_ritchie

  In the last post, I showed how to create a podcast using WCF syndication.  A podcast is an RSS feed containing a list of audio files to which users can subscribe.  The podcast not only contains links to the audio files, but also metadata about each episode.  A cool approach to building the feed is reading this metadata from the ID3 tags on the MP3 files used for the podcast. One library to do this is TagLib-Sharp.  Here is some sample code: .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: var taggedFile = TagLib.File.Create(f); 2: var fileInfo = new FileInfo(f); 3: var item = new iTunesPodcastItem() 4: { 5: title = taggedFile.Tag.Title, 6: size = fileInfo.Length, 7: url = feed.baseUrl + fileInfo.Name, 8: duration = taggedFile.Properties.Duration, 9: mediaType = feed.mediaType, 10: summary = taggedFile.Tag.Comment, 11: subTitle = taggedFile.Tag.FirstAlbumArtist, 12: id = fileInfo.Name 13: }; 14: if (!string.IsNullOrEmpty(taggedFile.Tag.Album)) 15: item.publishedDate = DateTimeOffset.Parse(taggedFile.Tag.Album); This reads the ID3 tags into an object for later use in creating the syndication feed.  When the MP3 is created, these tags are set...or they can be set after the fact using the Properties dialog in Windows Explorer.  The only "hack" is that there isn't an easily accessible tag for "subtitle" or "published date" so I used other tags in this example. Feel free to change this to meet your purposes.  You could remove the subtitle & use the file modified data for example. That takes care of the episodes, for the feed level settings we'll load those from an XML file: .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: <?xml version="1.0" encoding="utf-8" ?> 2: <iTunesPodcastFeed 3: baseUrl ="" 4: title="" 5: subTitle="" 6: description="" 7: copyright="" 8: category="" 9: ownerName="" 10: ownerEmail="" 11: mediaType="audio/mp3" 12: mediaFiles="*.mp3" 13: imageUrl="" 14: link="" 15: /> Here is the full code put together. Read the feed XML file and deserialize it into an iTunesPodcastFeed classLoop over the files in a directory reading the ID3 tags from the audio files .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: public static iTunesPodcastFeed CreateFeedFromFiles(string podcastDirectory, string podcastFeedFile) 2: { 3: XmlSerializer serializer = new XmlSerializer(typeof(iTunesPodcastFeed)); 4: iTunesPodcastFeed feed; 5: using (var fs = File.OpenRead(Path.Combine(podcastDirectory, podcastFeedFile))) 6: { 7: feed = (iTunesPodcastFeed)serializer.Deserialize(fs); 8: } 9: foreach (var f in Directory.GetFiles(podcastDirectory, feed.mediaFiles)) 10: { 11: try 12: { 13: var taggedFile = TagLib.File.Create(f); 14: var fileInfo = new FileInfo(f); 15: var item = new iTunesPodcastItem() 16: { 17: title = taggedFile.Tag.Title, 18: size = fileInfo.Length, 19: url = feed.baseUrl + fileInfo.Name, 20: duration = taggedFile.Properties.Duration, 21: mediaType = feed.mediaType, 22: summary = taggedFile.Tag.Comment, 23: subTitle = taggedFile.Tag.FirstAlbumArtist, 24: id = fileInfo.Name 25: }; 26: if (!string.IsNullOrEmpty(taggedFile.Tag.Album)) 27: item.publishedDate = DateTimeOffset.Parse(taggedFile.Tag.Album); 28: feed.Items.Add(item); 29: } 30: catch 31: { 32: // ignore files that can't be accessed successfully 33: } 34: } 35: return feed; 36: } Usually putting a "try...catch" like this is bad, but in this case I'm just skipping over files that are locked while they are being uploaded to the web site.Here is the code from the last couple of posts.

• 2D Selective Gaussian Blur

  - by Joshua Thomas

  I am attempting to use Gaussian blur on a 2D platform game, selectively blurring specific types of platforms with different amounts. I am currently just messing around with simple test code, trying to get it to work correctly. What I need to eventually do is create three separate render targets, leave one normal, blur one slightly, and blur the last heavily, then recombine on the screen. Where I am now is I have successfully drawn into a new render target and performed the gaussian blur on it, but when I draw it back to the screen everything is purple aside from the platforms I drew to the target. This is my .fx file: #define RADIUS 7 #define KERNEL_SIZE (RADIUS * 2 + 1) //----------------------------------------------------------------------------- // Globals. //----------------------------------------------------------------------------- float weights[KERNEL_SIZE]; float2 offsets[KERNEL_SIZE]; //----------------------------------------------------------------------------- // Textures. //----------------------------------------------------------------------------- texture colorMapTexture; sampler2D colorMap = sampler_state { Texture = <colorMapTexture>; MipFilter = Linear; MinFilter = Linear; MagFilter = Linear; }; //----------------------------------------------------------------------------- // Pixel Shaders. //----------------------------------------------------------------------------- float4 PS_GaussianBlur(float2 texCoord : TEXCOORD) : COLOR0 { float4 color = float4(0.0f, 0.0f, 0.0f, 0.0f); for (int i = 0; i < KERNEL_SIZE; ++i) color += tex2D(colorMap, texCoord + offsets[i]) * weights[i]; return color; } //----------------------------------------------------------------------------- // Techniques. //----------------------------------------------------------------------------- technique GaussianBlur { pass { PixelShader = compile ps_2_0 PS_GaussianBlur(); } } This is the code I'm using for the gaussian blur: public Texture2D PerformGaussianBlur(Texture2D srcTexture, RenderTarget2D renderTarget1, RenderTarget2D renderTarget2, SpriteBatch spriteBatch) { if (effect == null) throw new InvalidOperationException("GaussianBlur.fx effect not loaded."); Texture2D outputTexture = null; Rectangle srcRect = new Rectangle(0, 0, srcTexture.Width, srcTexture.Height); Rectangle destRect1 = new Rectangle(0, 0, renderTarget1.Width, renderTarget1.Height); Rectangle destRect2 = new Rectangle(0, 0, renderTarget2.Width, renderTarget2.Height); // Perform horizontal Gaussian blur. game.GraphicsDevice.SetRenderTarget(renderTarget1); effect.CurrentTechnique = effect.Techniques["GaussianBlur"]; effect.Parameters["weights"].SetValue(kernel); effect.Parameters["colorMapTexture"].SetValue(srcTexture); effect.Parameters["offsets"].SetValue(offsetsHoriz); spriteBatch.Begin(0, BlendState.Opaque, null, null, null, effect); spriteBatch.Draw(srcTexture, destRect1, Color.White); spriteBatch.End(); // Perform vertical Gaussian blur. game.GraphicsDevice.SetRenderTarget(renderTarget2); outputTexture = (Texture2D)renderTarget1; effect.Parameters["colorMapTexture"].SetValue(outputTexture); effect.Parameters["offsets"].SetValue(offsetsVert); spriteBatch.Begin(0, BlendState.Opaque, null, null, null, effect); spriteBatch.Draw(outputTexture, destRect2, Color.White); spriteBatch.End(); // Return the Gaussian blurred texture. game.GraphicsDevice.SetRenderTarget(null); outputTexture = (Texture2D)renderTarget2; return outputTexture; } And this is the draw method affected: public void Draw(SpriteBatch spriteBatch) { device.SetRenderTarget(maxBlur); spriteBatch.Begin(); foreach (Brick brick in blueBricks) brick.Draw(spriteBatch); spriteBatch.End(); blue = gBlur.PerformGaussianBlur((Texture2D) maxBlur, helperTarget, maxBlur, spriteBatch); spriteBatch.Begin(); device.SetRenderTarget(null); foreach (Brick brick in redBricks) brick.Draw(spriteBatch); foreach (Brick brick in greenBricks) brick.Draw(spriteBatch); spriteBatch.Draw(blue, new Rectangle(0, 0, blue.Width, blue.Height), Color.White); foreach (Brick brick in purpleBricks) brick.Draw(spriteBatch); spriteBatch.End(); } I'm sorry about the massive brick of text and images(or not....new user, I tried, it said no), but I wanted to get my problem across clearly as I have been searching for an answer to this for quite a while now. As a side note, I have seen the bloom sample. Very well commented, but overly complicated since it deals in 3D; I was unable to take what I needed to learn form it. Thanks for any and all help.

• Implementing synchronous MediaTypeFormatters in ASP.NET Web API

  - by cibrax

  One of main characteristics of MediaTypeFormatter’s in ASP.NET Web API is that they leverage the Task Parallel Library (TPL) for reading or writing an model into an stream. When you derive your class from the base class MediaTypeFormatter, you have to either implement the WriteToStreamAsync or ReadFromStreamAsync methods for writing or reading a model from a stream respectively. These two methods return a Task, which internally does all the serialization work, as it is illustrated bellow. public abstract class MediaTypeFormatter { public virtual Task WriteToStreamAsync(Type type, object value, Stream writeStream, HttpContent content, TransportContext transportContext); public virtual Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger); }   .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } However, most of the times, serialization is a safe operation that can be done synchronously. In fact, many of the serializer classes you will find in the .NET framework only provide sync methods. So the question is, how you can transform that synchronous work into a Task ?. Creating a new task using the method Task.Factory.StartNew for doing all the serialization work would be probably the typical answer. That would work, as a new task is going to be scheduled. However, that might involve some unnecessary context switches, which are out of our control and might be affect performance on server code specially.   If you take a look at the source code of the MediaTypeFormatters shipped as part of the framework, you will notice that they actually using another pattern, which uses a TaskCompletionSource class. public Task WriteToStreamAsync(Type type, object value, Stream writeStream, HttpContent content, TransportContext transportContext) {   var tsc = new TaskCompletionSource<AsyncVoid>(); tsc.SetResult(default(AsyncVoid));   //Do all the serialization work here synchronously   return tsc.Task; }   /// <summary> /// Used as the T in a "conversion" of a Task into a Task{T} /// </summary> private struct AsyncVoid { } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } They are basically doing all the serialization work synchronously and using a TaskCompletionSource for returning a task already done. To conclude this post, this is another approach you might want to consider when using serializers that are not compatible with an async model. Update: Henrik Nielsen from the ASP.NET team pointed out the existence of a built-in media type formatter for writing sync formatters. BufferedMediaTypeFormatter http://t.co/FxOfeI5x

• Which of these algorithms is best for my goal?

  - by JonathonG

  I have created a program that restricts the mouse to a certain region based on a black/white bitmap. The program is 100% functional as-is, but uses an inaccurate, albeit fast, algorithm for repositioning the mouse when it strays outside the area. Currently, when the mouse moves outside the area, basically what happens is this: A line is drawn between a pre-defined static point inside the region and the mouse's new position. The point where that line intersects the edge of the allowed area is found. The mouse is moved to that point. This works, but only works perfectly for a perfect circle with the pre-defined point set in the exact center. Unfortunately, this will never be the case. The application will be used with a variety of rectangles and irregular, amorphous shapes. On such shapes, the point where the line drawn intersects the edge will usually not be the closest point on the shape to the mouse. I need to create a new algorithm that finds the closest point to the mouse's new position on the edge of the allowed area. I have several ideas about this, but I am not sure of their validity, in that they may have far too much overhead. While I am not asking for code, it might help to know that I am using Objective C / Cocoa, developing for OS X, as I feel the language being used might affect the efficiency of potential methods. My ideas are: Using a bit of trigonometry to project lines would work, but that would require some kind of intense algorithm to test every point on every line until it found the edge of the region... That seems too resource intensive since there could be something like 200 lines that would have each have to have as many as 200 pixels checked for black/white.... Using something like an A* pathing algorithm to find the shortest path to a black pixel; however, A* seems resource intensive, even though I could probably restrict it to only checking roughly in one direction. It also seems like it will take more time and effort than I have available to spend on this small portion of the much larger project I am working on, correct me if I am wrong and it would not be a significant amount of code (100 lines or around there). Mapping the border of the region before the application begins running the event tap loop. I think I could accomplish this by using my current line-based algorithm to find an edge point and then initiating an algorithm that checks all 8 pixels around that pixel, finds the next border pixel in one direction, and continues to do this until it comes back to the starting pixel. I could then store that data in an array to be used for the entire duration of the program, and have the mouse re-positioning method check the array for the closest pixel on the border to the mouse target position. That last method would presumably execute it's initial border mapping fairly quickly. (It would only have to map between 2,000 and 8,000 pixels, which means 8,000 to 64,000 checked, and I could even permanently store the data to make launching faster.) However, I am uncertain as to how much overhead it would take to scan through that array for the shortest distance for every single mouse move event... I suppose there could be a shortcut to restrict the number of elements in the array that will be checked to a variable number starting with the intersecting point on the line (from my original algorithm), and raise/lower that number to experiment with the overhead/accuracy tradeoff. Please let me know if I am over thinking this and there is an easier way that will work just fine, or which of these methods would be able to execute something like 30 times per second to keep mouse movement smooth, or if you have a better/faster method. I've posted relevant parts of my code below for reference, and included an example of what the area might look like. (I check for color value against a loaded bitmap that is black/white.) // // This part of my code runs every single time the mouse moves. // CGPoint point = CGEventGetLocation(event); float tX = point.x; float tY = point.y; if( is_in_area(tX,tY, mouse_mask)){ // target is inside O.K. area, do nothing }else{ CGPoint target; //point inside restricted region: float iX = 600; // inside x float iY = 500; // inside y // delta to midpoint between iX,iY and tX,tY float dX; float dY; float accuracy = .5; //accuracy to loop until reached do { dX = (tX-iX)/2; dY = (tY-iY)/2; if(is_in_area((tX-dX),(tY-dY),mouse_mask)){ iX += dX; iY += dY; } else { tX -= dX; tY -= dY; } } while (abs(dX)>accuracy || abs(dY)>accuracy); target = CGPointMake(roundf(tX), roundf(tY)); CGDisplayMoveCursorToPoint(CGMainDisplayID(),target); } Here is "is_in_area(int x, int y)" : bool is_in_area(NSInteger x, NSInteger y, NSBitmapImageRep *mouse_mask){ NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; NSUInteger pixel[4]; [mouse_mask getPixel:pixel atX:x y:y]; if(pixel[0]!= 0){ [pool release]; return false; } [pool release]; return true; }

• Retrieving recent tweets using LINQ

  - by brian_ritchie

  There are a few different APIs for accessing Twitter from .NET.  In this example, I'll use linq2twitter.  Other APIs can be found on Twitter's development site. First off, we'll use the LINQ provider to pull in the recent tweets. .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: public static Status[] GetLatestTweets(string screenName, int numTweets) 2: { 3: try 4: { 5: var twitterCtx = new LinqToTwitter.TwitterContext(); 6: var list = from tweet in twitterCtx.Status 7: where tweet.Type == StatusType.User && 8: tweet.ScreenName == screenName 9: orderby tweet.CreatedAt descending 10: select tweet; 11: // using Take() on array because it was failing against the provider 12: var recentTweets = list.ToArray().Take(numTweets).ToArray(); 13: return recentTweets; 14: } 15: catch 16: { 17: return new Status[0]; 18: } 19: } Once they have been retrieved, they would be placed inside an MVC model. Next, the tweets need to be formatted for display. I've defined an extension method to aid with date formatting: .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: public static class DateTimeExtension 2: { 3: public static string ToAgo(this DateTime date2) 4: { 5: DateTime date1 = DateTime.Now; 6: if (DateTime.Compare(date1, date2) >= 0) 7: { 8: TimeSpan ts = date1.Subtract(date2); 9: if (ts.TotalDays >= 1) 10: return string.Format("{0} days", (int)ts.TotalDays); 11: else if (ts.Hours > 2) 12: return string.Format("{0} hours", ts.Hours); 13: else if (ts.Hours > 0) 14: return string.Format("{0} hours, {1} minutes", 15: ts.Hours, ts.Minutes); 16: else if (ts.Minutes > 5) 17: return string.Format("{0} minutes", ts.Minutes); 18: else if (ts.Minutes > 0) 19: return string.Format("{0} mintutes, {1} seconds", 20: ts.Minutes, ts.Seconds); 21: else 22: return string.Format("{0} seconds", ts.Seconds); 23: } 24: else 25: return "Not valid"; 26: } 27: } Finally, here is the piece of the view used to render the tweets. .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: <ul class="tweets"> 2: <% 3: foreach (var tweet in Model.Tweets) 4: { 5: %> 6: <li class="tweets"> 7: <span class="tweetTime"><%=tweet.CreatedAt.ToAgo() %> ago</span>: 8: <%=tweet.Text%> 9: </li> 10: <%} %> 11: </ul>

• SQL SERVER – Difference between DATABASEPROPERTY and DATABASEPROPERTYEX

  - by pinaldave

  Earlier I asked a simple question on Facebook regarding difference between DATABASEPROPERTY and DATABASEPROPERTYEX in SQL Server. You can view the original conversation there over here. The conversion immediately became very interesting and lots of healthy discussion happened on facebook page. The best part of having conversation on facebook page is the comfort it provides and leaner commenting interface. Question Question from SQLAuthority.com: What is the difference between DATABASEPROPERTY and DATABASEPROPERTYEX in SQL Server? Answer Answer from Rakesh Kumar: DATABASEPROPERTY is supported for backward compatibility but does not provide information about the properties added in this release. Also, many properties supported by DATABASEPROPERTY have been replaced by new properties in DATABASEPROPERTYEX.- source (MSDN). Answer from Alphonso Jones: The only real difference I can see is one, the number of properties contained and the other is that EX returns a sql_variant while DATABASEPROPERTY returns only int. Answer from Ambati Venkatasiva: Both are system meta data functions. DATABASEPROPERTYEX Returns the current setting of the specified database option. DATABASEPROPERTYEX returns the sq-varient value and DATABASEPROPERTY returns integer value. Answer from Rama Sankar Molleti:  Here is the best example about databasepropertyex SELECT DATABASEPROPERTYEX('dbname', 'Collation') Result SQL_1xCompat_CP850_CI_AS Whereas with databaseproperty it retuns nothing as the return type for this is integer. Sql_variant datatype stores values of various sql server supported datatypes except text, ntext, image and timestamp. Answer from Alok Seth:  SELECT DATABASEPROPERTYEX('AdventureWorks', 'Status') DatabaseStatus_DATABASEPROPERTYEX GO --Result - ONLINE SELECT DATABASEPROPERTY('AdventureWorks', 'Status') DatabaseStatus_DATABASEPROPERTY GO --Result - NULL Summary Use DATABASEPROPERTYEX as it is the only function supported in future version as well it returns status of various database properties which does not exists with DATABASEPROPERTY.
