• Silverlight Cream for March 14, 2011 -- #1060

  - by Dave Campbell

  In this Issue: Lazar Nikolov, Rudi Grobler, WindowsPhoneGeek, Jesse Liberty, Pete Brown, Jessica Foster, Chris Rouw, Andy Beaulieu, and Colin Eberhardt. Above the Fold: Silverlight: "A Silverlight Resizable TextBlock (and other resizable things)" Colin Eberhardt WP7: "Retrofitting the Trial API" Jessica Foster Shoutouts: Rudi Grobler has a post up that's not Silverlight, but it's cool stuff you may be interested in: WPF Themes now available on NuGet From SilverlightCream.com: Simulating rain in Silverlight Lazar Nikolov has a cool tutorial up at SilverlightShow... Simulating rain. Nice demo near to top, and source code plus a very nice tutorial on the entire process. Making the ApplicationBar bindable Rudi Grobler has a couple new posts up... first this one on making the WP7 AppBar bindable... he's created 2 simple wrappers that make it possible to bind to a method... with source as usual! All about Splash Screens in WP7 – Creating animated Splash Screen WindowsPhoneGeek's latest is about splash screens in WP7, but he goes one better with animated splash screens. Lots of good information including closing points in more of a FAQ-style listing. Testing Network Availability Jesse Liberty's latest is on testing for network availability in your WP7 app. This should be required reading for anyone building a WP7 app, since you never know when the network is going to be there or not. Lighting up on Windows 7 with Native Extensions for Microsoft Silverlight Pete Brown's latest post is about the Native Extensions for Microsoft Silverlight or NESL library. Pete describes what NESL is, a link to the library, installing it, and tons more information. If you wanna know or try NESL... this looks like the place to start. Retrofitting the Trial API Jessica Foster paused on the way to shipping her WP7 app to add in the trial API code. Check out what she went through to complete that task, as she explains the steps and directions she took. Good description, links, and code. WP7 Insights #2: Creating a Splash Screen in WP7 In the 2nd post in his series on WP7 development, Chris Rouw is discussing a WP7 splash screen. He gives some good external links for references then gets right into discussing his code. Air Hockey for Windows Phone 7 Andy Beaulieu shares a tutorial he wrote for the Expression Toolbox site, using the Physics Helper Library and Farseer Physics Engine -- an Air Hockey game for WP7. A Silverlight Resizable TextBlock (and other resizable things) I think Michael Washington had the best comment about Colin Eberhardt's latest outing: "Another WOW example" ... drop this in the pretty darn cool category: an attached behavior that uses a Thumb control within a popup to adorn any UI element to allow the user to resize it!

• Easy Scaling in XAML (WPF)

  - by Robert May

  Ran into a problem that needed solving that was kind of fun.  I’m not a XAML guru, and I’m sure there are better solutions, but I thought I’d share mine. The problem was this:  Our designer had, appropriately, designed the system for a 1920 x 1080 screen resolution.  This is for a full screen, touch screen device (think Kiosk), which has that resolution, but we also wanted to demo the device on a tablet (currently using the AWESOME Samsung tablet given out at Microsoft Build).  When you’d run it on that tablet, things were ugly because it was at a lower resolution than the target device. Enter scaling.  I did some research and found out that I probably just need to monkey with the LayoutTransform of some grid somewhere.  This project is using MVVM and has a navigation container that we built that lives on a single root view.  User controls are then loaded into that view as navigation occurs. In the parent grid of the root view, I added the following XAML: <Grid.LayoutTransform> <ScaleTransform ScaleX="{Binding ScaleWidth}" ScaleY="{Binding ScaleHeight}" /> </Grid.LayoutTransform> And then in the root View Model, I added the following code: /// <summary> /// The required design width /// </summary> private const double RequiredWidth = 1920; /// <summary> /// The required design height /// </summary> private const double RequiredHeight = 1080; /// <summary>Gets the ActualHeight</summary> public double ActualHeight { get { return this.View.ActualHeight; } } /// <summary>Gets the ActualWidth</summary> public double ActualWidth { get { return this.View.ActualWidth; } } /// <summary> /// Gets the scale for the height. /// </summary> public double ScaleHeight { get { return this.ActualHeight / RequiredHeight; } } /// <summary> /// Gets the scale for the width. /// </summary> public double ScaleWidth { get { return this.ActualWidth / RequiredWidth; } } Note that View.ActualWidth and View.ActualHeight are just pointing directly at FrameworkElement.ActualWidth and FrameworkElement.ActualHeight. That’s it.  Just calculate the ratio and bind the scale transform to it. Hopefully you’ll find this useful. Technorati Tags: WPF,XAML

• Dual Monitor results in 'greyed' windows

  - by paula

  This occurs in Maverick and Natty. Single screen is fine, mirror of single screen is fine. If the mirror box is unchecked and the second monitor is turned on to extend the desktop then all windows are greyed out (like they do when a process has timed out and is unresponsive) and pop up menus are greyed out but icons, panels and background are fine and the windows do operate (just can't see them well enough to use) I have a D620 with intel graphics. This machine did work with dual monitors at some time in the past, however I have been using another machine, a D630 with nvidia and it works fine. Yes, there have been any number of updates. I also upgraded from Maverick to Natty to see if it would go away. No joy. Also, the D620 has a dual boot windows system and the windows xp system works fine with daul monitors There is a forum thread that goes into more detail and there are a number of users experiencing this problem. Thread: greyed out windows Thanks for reading paula_ke

• MySQL - ODBC Data Connector

  - by Stuart Brierley

  Having previsouly installed and then configured MySQL, you may now need to install the ODBC Data Connector driver in order to connect to your MySQL database. Following the Splash screen the first thing to choose is the Setup Type for your installation.  As usual I chose custom so that I could see the components that were actually being installed.  In this case the custom set up screen allows you to choose to install the driver and the documentation. Finally you can complete the installation Assuming it completes okay you have now installed the MySQL ODBC driver. My intention for installing all these MySQL components is so that I can now attempt to get BizTalk 2009 talking to the MySQL database for a solution that I am currently working on.  For this I will next be looking at the Community ODBC Adapter.

• Brainworkshop won't go fullscreen

  - by user1777025

  I am unable to run brainworkshop in fullscreen mode. After correctly changing the config.ini file to launch the script in fullscreen mode all I get is a window of the same size as before but with no frame or title bar, aligned to the top right (below the menu bar and to the right of the edge of the screen). I tried posting a screenshot but as I'm a new user I wasn't allowed to... I tried looking around in the pyglet files to see if I could find anything that might be causing this but it's all beyond me. Any suggestions? Right after posting this I relaunched the script and now the same borderless, resizeable window is launched aligned to the bottom right hand corner of the screen... I'm running ubuntu 12.04 and brainworkshop 4.8.4.

• Cannot dual Windows XP and Ubuntu

  - by Fabio Machado

  I am new to Ubuntu and at the moment I am trying to get Ubuntu 12.10 to one of my machines. The machine is a Pentium 4 @ 3.06, 2Gb RAM, 200GB Hard Drive and a NVidia GeForce 8800 GT. A few days ago, I tried Ubuntu without installing and it worked perfectly. Yesterday, I decided to formatted the hard drive and divide my hard drive into four partitions: 1 for the XP, 1 for Ubuntu, 1 for swamp and 1 where I will have my documents. Everything went great, I installed XP and then Ubuntu but I did something wrong on the partition window (Ubunto partion window) that I ended up without boot loader. This morning, I formatted everything again, installed XP and when I went to install Ubuntu (with the same DVD as before) the problems started. First, I had a black screen with a msg written with white text saying something like: unable to find a medium containing a live file system. After I burned another CD and tried again, I got stuck at the red dots (loading screen). I then went online and I read somewhere that it could be the CD, so I checked the integrity of the CD and everything was fine. I also unplugged all USBs connected to the computer and nothing changed. I goggled further options to try to solve my problem and some users suggested that people having these types of problems should try the alternate installation, which if I am not wrong is for networks. I then tried to install and yes the installation process was different from the normal CD, but it did get stuck on a page where it was doing something, like: ...finding ethd0 and it was stuck on the 100%. I tried USB installation as well and it also got stuck at the red dots (I do not have USB 3.0 on the computer in question). I have burned 5 different CD's and all at low speed. I checked the integrity and all are fine. I downloaded other distribution as well as other versions of Ubuntu and I still cannot install or even run the Live CD of Ubuntu or any other distribution. What is really annoying me is that everything was working perfectly before, when I first tried to install Ubuntu. Anyway, any help is welcome. Edit: My boot load is normal, no errors and all the hardware is working fine. I forgot to mention that after the loading screen (red dots) gets stuck, the DVD drive and the hard drive goes into idle state. I also restored the default values of the BIOS and no luck.

• Adjust resolution in xfce4 virtualbox guest guest

  - by David

  I have Virtualbox 4.1.2_ubuntur3859 installed on an Ubuntu 11.10 host, running a guest ubuntu server 10.04 with xfce4 and xorg installed with no-install-recommends. I have installed guest additions, but the maximum resolution in the display settings is 800x600. I have read related questions: How to change resolution of the VirtualBox (Ubuntu guest and host)? Higher screen resolution in VirtualBox? upgrading VirtualBox 3.2.10 breaks my guest Ubuntu screen resolution Ubuntu as guest OS (with Vista host) stuck at 800x600 resolution but none contain the solution to my issue. Am I missing any particular packages that would allow me to change resolution? I would like to keep the machine as small as possible.

• Display resolution problem with Sony TV and Intel integrated graphics

  - by user96195

  I am trying to set the correct display resolution for my Sony TV (KDL-32V2000, native resolution 1366x768) connected via HDMI to my HTPC running Ubuntu 12.04. I have a Intel Core i3-530 and Intel mobo (DH57JG), so no proprietary graphics drivers. The problem is that I can't get the correct resolution to display on the TV. Initially I only had 1024x768 (or similar) as a maximum resolution, which was not displayed properly. I tried a few steps, including generating an xorg.conf (initially didn't have one) and adding the segment as described in this post regarding this particular TV. I couldn't get this to work, and at this stage have reverted to running without an xorg.conf. Another post suggested upgrading to kernel 3.5, which did give me a 1920x1080 resolution option. This results in the TV cutting off a fair bit of the edges of the screen. My Dell laptop with ATI drivers recognises the TV screen and works well via HDMI. Any idea how to proceed?

• SOA+OSB in same JVM

  - by Manoj Neelapu

  Oracle Service Bus 11gR1 (11.1.1.3) supports running in same JVM as SOA. This tutorial covers on how to do create domain in of SOA+OSB combined to run in single JVM . For this tutorial we will use a flavor  WebLogic installer bundled with both OEPE and coherence components (eg oepe111150_wls1033_win32.exe). WebLogic installer bundled with coherence and OEPE components can be seen in the screen shot.Oracle Service Bus 11gR1 (11.1.1.3) has built-in caching support for Business Services using coherence. Because of this we will have to install coherence before  installing OSB.  To get soa and osb running in the same domain, we have to install the SOA and OSB on the above ORACLE_HOME. After installation we should see both the SOA and OSB homes has highlighted in red.We could also see the coherence components which is mandatory for OSB and optional OEPE also installed.Now we will execute RCU(ofm_rcu_win_11.1.1.3.0_disk1_1of1) to install the schema for SOA and OSB. New RCU contains OSB tables (WLI_QS_REPORT_DATA , WLI_QS_REPORT_ATTRIBUTE) gets loaded as part of SOAINFRA schema After this step we will have to create soa+osb domain using config wizard. It is located under $WEBLOGIC_HOME\common\bin\config.* (.cmd or .sh as per your platform) .While creating a domain we will select options for SOA Suite  and Oracle Service Bus Extension-All Domain Topologies.There is another option for OSB  Oracle Service Bus Extension-Single server Domain Topology. This topology is for users who want to use OSB in single server configuration. Currently SOA doesn't support single server topology. So this topology cannot be used with SOA domain but can only be used for stand alone OSB installations.We can continue with domain configuration till we reach the below screen. Following steps are mandatory if we want to have the SOA and OSB run in same JVMwe should select Managed Server, Clusters and Machines as shown below After this selection you should see a screen with two servers One managed server for OSB and one managed for SOA. Since we would like to have both the servers in one managed server (one JVM) we will have to do one important step here. We have to delete either of the servers and rename the other server with deleted server name.eg delete osb_server1 and rename the soa_server1 to osb_server1 or we can also delete soa_server1 and rename the osb_server1 to soa_server1After this steps proceed as as-usual . If we observe created domain we see only one managed server which contains components for both SOA and OSB ($DOMAIN_HOME/startManagedWebLogic_readme.txt).

• Most commands won't do anything if I use the console at my Ubuntu server. Why?

  - by Tijs

  I've bought a vps server a few days ago, with Ubuntu on it, but I have a problem now. By nearly all the commands I put in I get this error: : command not found. I am logging in as root. I think this is the Ubuntu version I have: ubuntu-8.04-i386-minimal. (Maybe it has to do with 'minimal'? I really don't know.) To be more specific, the command I have and try to run now is this: cd ~/mclawl; screen -S MCForge -d -m -c /dev/null -- sh -c 'mono MCForge.exe; exec $SHELL' If I do so, I get this: -bash: screen: command not found

• Off center projection

  - by N0xus

  I'm trying to implement the code that was freely given by a very kind developer at the following link: http://forum.unity3d.com/threads/142383-Code-sample-Off-Center-Projection-Code-for-VR-CAVE-or-just-for-fun Right now, all I'm trying to do is bring it in on one camera, but I have a few issues.

Thus, I changed the line to read: projectionM = new PerspectiveOffCenter(left, right, bottom, top, near, far); But then the error is changed to: The type 'PerspectiveOffCenter' does not contain a constructor that takes '6' arguments. For reasons that are obvious. So, finally, I changed the line to read: projectionM = new GeneralizedPerspectiveProjection(left, right, bottom, top, near, far); And the error I get is: is a 'method' but a 'type' was expected. With this last error, I'm not sure what it is I should do / missing. Can anyone see what it is that I'm missing to fix this error?

• SDL to SFML simple question

  - by ultifinitus

  Hey! I've been working on a game in c++ for about a week and a half, and I've been using SDL. However, my current engine only needs the following from whatever library I use: enable double buffering load an image from path into something that I can apply to the screen apply an image to the screen with a certain x,y enable transparency on an image (possibly) image clipping, for sprite sheets. I am fairly sure that SFML has all of this functionality, I'm just not positive. Will someone confirm my suspicions? Also I have one or two questions regarding SFML itself. Do I have to do anything to enable hardware accelerated rendering? How quick is SFML at blending alpha values? (sorry for the less than intelligent question!)

  I am trying to upgrade from Ubuntu 12.04 to 14.04 on a laptop. I have run sudo do-release-upgrade During the upgrade process the laptop went into sleep/locked screen mode. I have rebooted and noticed that dependencies are broken. Running: lsb_release -a shows that the version has been upgraded to 14.04. However, the upgrade process did not finish(there was no output, I had to restart the workstation as the screen was blinking continuously). Now, following this question I have run sudo apt-get -u dist-upgrade and am now waiting for the process to finish.

• How can I adjust system volume from within XBMC?

  - by d3vid

  While running XBMC, I can adjust the volume of the XBMC application itself. However, this volume is limited by the current system volume. For example, if the system volume is at 80% and XBMC is at 100%, I am effectively at 80% and cannot go higher. Or if the sound is too soft and needs a boost, I would normally increase the system volume beyond 100%. XBMC takes over the whole screen, so the system volume is not accessible. Pressing the Super key brings up the dash and top menu, but clicking on it is difficult and inconsistent, and very quickly XBMC takes over the screen again. How can I adjust the system volume without having to quit XBMC?

• How To Get Web Site Thumbnail Image In ASP.NET

  - by SAMIR BHOGAYTA

  Overview One very common requirement of many web applications is to display a thumbnail image of a web site. A typical example is to provide a link to a dynamic website displaying its current thumbnail image, or displaying images of websites with their links as a result of search (I love to see it on Google). Microsoft .NET Framework 2.0 makes it quite easier to do it in a ASP.NET application. Background In order to generate image of a web page, first we need to load the web page to get their html code, and then this html needs to be rendered in a web browser. After that, a screen shot can be taken easily. I think there is no easier way to do this. Before .NET framework 2.0 it was quite difficult to use a web browser in C# or VB.NET because we either have to use COM+ interoperability or third party controls which becomes headache later. WebBrowser control in .NET framework 2.0 In .NET framework 2.0 we have a new Windows Forms WebBrowser control which is a wrapper around old shwdoc.dll. All you really need to do is to drop a WebBrowser control from your Toolbox on your form in .NET framework 2.0. If you have not used WebBrowser control yet, it's quite easy to use and very consistent with other Windows Forms controls. Some important methods of WebBrowser control are. public bool GoBack(); public bool GoForward(); public void GoHome(); public void GoSearch(); public void Navigate(Uri url); public void DrawToBitmap(Bitmap bitmap, Rectangle targetBounds); These methods are self explanatory with their names like Navigate function which redirects browser to provided URL. It also has a number of useful overloads. The DrawToBitmap (inherited from Control) draws the current image of WebBrowser to the provided bitmap. Using WebBrowser control in ASP.NET 2.0 The Solution Let's start to implement the solution which we discussed above. First we will define a static method to get the web site thumbnail image. public static Bitmap GetWebSiteThumbnail(string Url, int BrowserWidth, int BrowserHeight, int ThumbnailWidth, int ThumbnailHeight) { WebsiteThumbnailImage thumbnailGenerator = new WebsiteThumbnailImage(Url, BrowserWidth, BrowserHeight, ThumbnailWidth, ThumbnailHeight); return thumbnailGenerator.GenerateWebSiteThumbnailImage(); } The WebsiteThumbnailImage class will have a public method named GenerateWebSiteThumbnailImage which will generate the website thumbnail image in a separate STA thread and wait for the thread to exit. In this case, I decided to Join method of Thread class to block the initial calling thread until the bitmap is actually available, and then return the generated web site thumbnail. public Bitmap GenerateWebSiteThumbnailImage() { Thread m_thread = new Thread(new ThreadStart(_GenerateWebSiteThumbnailImage)); m_thread.SetApartmentState(ApartmentState.STA); m_thread.Start(); m_thread.Join(); return m_Bitmap; } The _GenerateWebSiteThumbnailImage will create a WebBrowser control object and navigate to the provided Url. We also register for the DocumentCompleted event of the web browser control to take screen shot of the web page. To pass the flow to the other controls we need to perform a method call to Application.DoEvents(); and wait for the completion of the navigation until the browser state changes to Complete in a loop. private void _GenerateWebSiteThumbnailImage() { WebBrowser m_WebBrowser = new WebBrowser(); m_WebBrowser.ScrollBarsEnabled = false; m_WebBrowser.Navigate(m_Url); m_WebBrowser.DocumentCompleted += new WebBrowserDocument CompletedEventHandler(WebBrowser_DocumentCompleted); while (m_WebBrowser.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); m_WebBrowser.Dispose(); } The DocumentCompleted event will be fired when the navigation is completed and the browser is ready for screen shot. We will get screen shot using DrawToBitmap method as described previously which will return the bitmap of the web browser. Then the thumbnail image is generated using GetThumbnailImage method of Bitmap class passing it the required thumbnail image width and height. private void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser m_WebBrowser = (WebBrowser)sender; m_WebBrowser.ClientSize = new Size(this.m_BrowserWidth, this.m_BrowserHeight); m_WebBrowser.ScrollBarsEnabled = false; m_Bitmap = new Bitmap(m_WebBrowser.Bounds.Width, m_WebBrowser.Bounds.Height); m_WebBrowser.BringToFront(); m_WebBrowser.DrawToBitmap(m_Bitmap, m_WebBrowser.Bounds); m_Bitmap = (Bitmap)m_Bitmap.GetThumbnailImage(m_ThumbnailWidth, m_ThumbnailHeight, null, IntPtr.Zero); } One more example here : http://www.codeproject.com/KB/aspnet/Website_URL_Screenshot.aspx

• Why does Chrome video performance substantially degrade after waking from suspend in 10.10?

  - by Grant Heaslip

  Note: For some more details, some of which may not be true given what I've figured out, see this post. When I first boot my computer, video performance (both native H.264 HTML5 in YouTube and Vimeo, and in Flash) in Chrome is perfectly reasonable. CPU usage stays slow, everything works correctly, and the video is silky-smooth. But for whatever reason, if I suspend my computer then wake it up, video performance plummets. Full screen HTML5 video is choppy at best, and full-screen Flash video basically brings my computer to its knees (I'm talking less than a frame a second, and a 5 second lead time to leave full-screen after hitting Esc). Restarting Chrome doesn't fix this — I need to completely restart my machine before performance goes back to normal. Video performance in other applications, such as Movie Player, doesn't seem to be affected at all by the suspend cycle — it's only Chrome. I'm using a Lenovo X201, with an Intel GMA HD graphics chipset, and Intel compnents all around (I don't need any proprietary drivers). This didn't happen in 10.04, and I haven't anything that I think would have caused this to happen. It's possible that a Chrome release could have caused this, but it seems less likely than a regression between 10.04 and 10.10. Any ideas? EDIT: In response Georg's comment, logging in and out doesn't fix it. Restarting Compiz or switching to Metacity (at least by using "compiz/metacity --replace & disown" — am I doing it right?) doesn't help (actually, it seemed to help somewhat with Flash once, but I haven't been able to reproduce this). I'm not sure about GDM — when I use "sudo restart gdm" I get kicked back to the Linux shell (?), which I have no idea how to get out of. Also, I want to make very clear that this isn't just a case of Flash sucking (it does,but that's beside the point). I"m seeing the same general problem with HTML5 videos, and Flash is performing better on my Nexus One than it does on my Core i5 laptop. There's something screwy going on with Chrome and/or 10.10.

• Ubuntu 12.10 Unity and Gnome not showing correctly after log in

  - by Luis Rodriguez

  Hello Ubuntu community. Since last Saturday when I was about to log into my ubuntu session as always using Unity interface, I came across with something that never happened to me before. When I logged in, the screen only showed the Desktop wallpaper but neither the bar from the top screen neither the dash bar from the left side appear, and after a few minutes of being logged in, I found myself being spammed with Ubuntu errors windows, over and over again. I logged out using ctrl+alt+del and tried my Gnome sessio. But I got exactly the same problem. I'm only able to use Gnome Classic and Classic (No Effects) Can anybody help? Hope a reply soon, and thanks in advance.

• Playing a Song causing WP7 to crash on phone, but not on emulator

  - by Michael Zehnich

  Hi there, I am trying to implement a song into a game that begins playing and continually loops on Windows Phone 7 via XNA 4.0. On the emulator, this works fine, however when deployed to a phone, it simply gives a black screen before going back to the home screen. Here is the rogue code in question, and commenting this code out makes the app run fine on the phone: // in the constructor fields private Song song; // in the LoadContent() method song = Content.Load<Song>("song"); // in the Update() method if (MediaPlayer.GameHasControl && MediaPlayer.State != MediaState.Playing) { MediaPlayer.Play(song); } The song file itself is a 2:53 long, 2.28mb .wma file at 106kbps bitrate. Again this works perfectly on emulator but does not run at all on phone. Thanks for any help you can provide!

• 12.04 How do I disable the long press Super key from showing the shortcuts window?

  - by pt123

  Note this is the long press and not the one for the short press as mentioned here How do I disable the Super key? The super key has been a modifier long before Unity came, and I have used it on Compiz Zoom feature. So holding super down and moving the mouse scroll would zoom in and out the screen. But now in 12.04 the shortcut list screen pops up and it is irritating. I have also tried changing the keys to control +super + mouse scroll and a similar thing happens. Is there anyway to disable or change the long press super key for this, I have searched Compiz Unity plugin, the Systems Preferences - Keyboard shortcuts settings and haven't been able to find this.

• Smooth animation in Cocos2d for iOS

  - by MrDatabase

  I move a simple CCSprite around the screen of an iOS device using this code: [self schedule:@selector(update:) interval:0.0167]; - (void) update:(ccTime) delta { CGPoint currPos = self.position; currPos.x += xVelocity; currPos.y += yVelocity; self.position = currPos; } This works however the animation is not smooth. How can I improve the smoothness of my animation? My scene is exceedingly simple (just has one full-screen CCSprite with a background image and a relatively small CCSprite that moves slowly). I've logged the ccTime delta and it's not consistent (it's almost always greater than my specified interval of 0.0167... sometimes up to a factor of 4x). I've considered tailoring the motion in the update method to the delta time (larger delta = larger movement etc). However given the simplicity of my scene it's seems there's a better way (and something basic that I'm probably missing).
