  • Problem virtualizing Ubuntu 10.04 32 bit on VirtualBox 3.1 on Windows Vista 64 bit

    - by Adam Siddhi
    Software & Hardware Setup Host System : Windows Vista Home Premium SP1 64 bit Guest : Ubuntu 10.04 (ubuntu-10.04-desktop-i386.iso) 32 bit VM : VirtualBox 3.1.8 Hardware : Intel Core 2 Duo T6400 4GB SDRAM What Happened I followed the tutorial called Installing Ubuntu inside Windows using VirtualBox located here: www.psychocats.net/ubuntu/virtualbox At first I downloaded ubuntu-10.04-desktop-amd64.iso because I figured that it would be a perfect fit with my Vista 64 OS. I was wrong because it turns out the my Intel Core 2 Duo T6400 CPU does not have Intel® Virtualization Technology. So I had to go with the ubuntu-10.04-desktop-i386.iso which is 32 bit. This got me to the point where I could actually create the Ubuntu VM. So I set up the VM in VirtualBox (according to the tutorial I was following) to prepare for the Ubuntu 10.04 virtualization. Please go to my Picassa web album to see the screen shots of my VM settings and Ubuntu boot process so you can see what I experienced (they appear in the order that I experienced them in). www.picasaweb.google.com/rubysiddhi/ProblemVirtualizingUbuntu100432BitOnVirtualBox31OnWindowsVista64# The first 17 images show the VM settings. The last 8 show my attempt at virtualizing Ubuntu 10.04. You can see booting up but ultimately failing. The Specifics The one error message I got was: (process:210): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0) It appeared on a black screen that sort of looked like a Windows console screen but with out the c:\ or the ability to type. Then this error message got more complex when tons of text appeared in the screen. Pictures 23 - 25 in the album show this text. I should also mention that I found this post in the Ubuntu forums by zonination who seemed to have similar problems to mine even though they had a different set up. The main issue I think zonination and me may be having is the fact that we can not change the color mode to 32 bit while it is booting. I think the 16 bit color mode maybe making Ubuntu fail. Not certain though. Well I hope I explained my problem thoroughly and clearly. Thanks for the tutorial. It got me started but, now I hope to finish this process so I can start developing in Ubuntu. OH by the way if you want to actually see what happened play by play (with some classical in the background) check out the video I made over here: http://www.youtube.com/watch?v=XMbbm5E_0Xw Thanks!

  • Confluence or apache on win server 2008 cant find scripts and images :(

    - by Ishak
    I am a newbie to both Tomcat and Apache. I have set the virtual hosts as described in Here. And JIRA works fine when i browse the URL jira.agmlab.com. However when i try to access Confluence(3.4.5) with confluence.agmlab.com the pages come in plain html, i can login and browse pages but there is no css or js so that my confluence pages look very ugly. what can possibly cause this and how to fix this? here is my virtual hosts definitions : # # Virtual Hosts # # If you want to maintain multiple domains/hostnames on your # machine you can setup VirtualHost containers for them. Most configurations # use only name-based virtual hosts so the server doesn't need to worry about # IP addresses. This is indicated by the asterisks in the directives below. # # Please see the documentation at # <URL:http://httpd.apache.org/docs/2.2/vhosts/> # for further details before you try to setup virtual hosts. # # You may use the command line option '-S' to verify your virtual host # configuration. # # Use name-based virtual hosting. # NameVirtualHost * # # VirtualHost example: # Almost any Apache directive may go into a VirtualHost container. # The first VirtualHost section is used for all requests that do not # match a ServerName or ServerAlias in any <VirtualHost> block. # <VirtualHost *> ServerName confluence.agmlab.com ProxyRequests Off ProxyPreserveHost On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://localhost:8081/confluence/ ProxyPassReverse / http://localhost:8081/confluence/ # ProxyHTMLURLMap /confluence/ / <Location /> Order allow,deny Allow from all </Location> </VirtualHost> <VirtualHost *> ServerName jira.agmlab.com ProxyRequests Off ProxyPreserveHost On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://localhost:8080/ ProxyPassReverse / http://localhost:8080/ <Location /> Order allow,deny Allow from all </Location> </VirtualHost> and i added 127.0.0.1 jira.agmlab.com 127.0.0.1 confluence.agmlab.com to my hosts file (i am using Win Server 2008 OS). here is part of the error log from Apache access.log file : 127.0.0.1 -

Can it be something related with the permissions defined in Win Server 2008 ? maybe there is not enough rights (such as read execute ) in some users, directories ??

  • Is it the address bus size or the data bus size that determines "8-bit , 16-bit ,32-bit ,64-bit " systems?

    - by learner
    My simple understanding is as follows. Memory (RAM) is composed of bits, groups of 8 which form bytes, each of which can be addressed ,and hence byte addressable memory. Address Bus stores the location of a byte of memory. If an address bus is of size 32 bits, that means it can hold upto 232 numbers and it hence can refer upto 232 bytes of memory = 4GB of memory and any memory greater than that is useless. Data bus is used to send the value to be written to/read off the memory. If I have a data bus of size 32 bits, it means a maximum of 4 bytes can be written to/read off the memory at a time. I find no relation between this size and the maximum memory size possible. But I read here that: Even though most systems are byte-addressable, it makes sense for the processor to move as much data around as possible. This is done by the data bus, and the size of the data bus is where the names 8-bit system, 16-bit system, 32-bit system, 64-bit system, etc.. come from. When the data bus is 8 bits wide, it can transfer 8 bits in a single memory operation. When the data bus is 32 bits wide (as is most common at the time of writing), at most, 32 bits can be moved in a single memory operation. This says that the size of the data bus is what gives an OS the name, 8bit, 16bit and so on. What is wrong with my understanding?

  • What are the common character animation techniques used in tile based hack&slash games?

    - by Gorky
    I wonder what kind of animation techniques are used for creature and character animation in modern hack&slash type tile based games? Keyframing for different actions may be one option. Skeletal framing may be another. But how about the physics? Or do they use a totally hybrid system of inverse kinematics supported with a skeleton,physics and mixed with interpolated keyframing for more realistic animations? If so, how and for what reasons? I can think of many different solutions for the issues below but I wonder what's used and best suited for issues like: Walking or moving on an uneven terrain Combat interaction, combat physics and collisions Attaching rigid items to character and their iteractions ih physics world Soft body dynamics like hair, vegetation, clothes and fabric in line with animations and iteractions.

  • How can a load and play an .x model using vertex animation in XNA?

    - by Christian
    From a game I developed years ago, I still have character models that my former 3D engine designer created and that I'd like to reuse in a Windows Phone project now. However, the files are in DirectX format (.x) containing keyframe animation only. No bones. No skeleton. There are a lot of animation keys defined on several frames to animate the characters. I don't quite understand how that works, to be frankly. However, I did a lot of research regarding a possible way of getting the characters animated via XNA on Windows Phone and all I found are hints that it is generally possible but not supported. Possibly by implementing own Content Importers and Processors. I didn't find anyone who successfully did something like that yet. How should I go about loading and displaying these models in XNA?

  • Problem playing repeat animation/action?

    I'm calling this function on multiple sprites after checking numberOfRunningActions()"to play same animation but it's not working only the first tagged sprite plays the animation. What am I doing wrong? void CGame::playAnimation(const char* filename, int tag, CCLayer* target) { CCAnimation* animation = CCAnimation::animation(); CCSprite* spriteSheet = CCSprite::spriteWithFile(filename); for(int i = 0; i < spriteSheet->getTexture()->getPixelsWide()/SIZE; i++) // SIZE is an int value { animation->addFrameWithTexture(spriteSheet->getTexture(), CCRect(SIZE * i, 0, SIZE, SIZE)); } CCActionInterval* action = CCAnimate::actionWithDuration(1, animation, true); CCRepeatForever* repeatAction = CCRepeatForever::actionWithAction(action); target->getChildByTag(tag)->runAction(repeatAction); }

But when I pass argument to it ( That is in the previous code ) , then it prints a space for any character. What should I do?

  • Problem Adding Windows 7 64-bit print drivers to 32-bit Windows 2003 Print Server

    - by Richard West
    I have installed the final RTM version of Windows 7 professional 64 bit on a test system before we begin the roll out in our company. I'm having problems connecting to several HP printers that we have on the network. These printers are being shared from a Windows 2003 server host. I have downloaded the lastest HP Universal Printer dirver, however I'm unable to add the 64 bit driver onto the 2003 server system (it's 32 bit). Does anyone have any advice on how I can get connected to these printers from the Windows 7 system?

  • On Windows 7, how to check that applications are in the correct Program Files directory?

    - by Anon Guy
    In Windows 7, applications should be installed to "Program Files" or "Program Files (x86)" depending on whether they are 64-bit or 32-bit (respectively, as per this page). Is there an easy way to check that all the applications on my system are in the correct Program Files directory? To put it another way, is an easy way to detect any 32-bit applications in "Program Files" and 64-bit applications in "Program Files (x86)"?

  • More Animation - Self Dismissing Dialogs

    - by Duncan Mills
    In my earlier articles on animation, I discussed various slide, grow and  flip transitions for items and containers.  In this article I want to discuss a fade animation and specifically the use of fades and auto-dismissal for informational dialogs.  If you use a Mac, you may be familiar with Growl as a notification system, and the nice way that messages that are informational just fade out after a few seconds. So in this blog entry I wanted to discuss how we could make an ADF popup behave in the same way. This can be an effective way of communicating information to the user without "getting in the way" with modal alerts. This of course, has been done before, but everything I've seen previously requires something like JQuery to be in the mix when we don't really need it to be.  The solution I've put together is nice and generic and will work with either <af:panelWindow> or <af:dialog> as a the child of the popup. In terms of usage it's pretty simple to use we  just need to ensure that the popup itself has clientComponent is set to true and includes the animation JavaScript (animateFadingPopup) on a popupOpened event: <af:popup id="pop1" clientComponent="true">   <af:panelWindow title="A Fading Message...">    ...  </af:panelWindow>   <af:clientListener method="animateFadingPopup" type="popupOpened"/> </af:popup>   The popup can be invoked in the normal way using showPopupBehavior or JavaScript, no special code is required there. As a further twist you can include an additional clientAttribute called preFadeDelay to define a delay before the fade itself starts (the default is 5 seconds) . To set the delay to just 2 seconds for example: <af:popup ...>   ...   <af:clientAttribute name="preFadeDelay" value="2"/>   <af:clientListener method="animateFadingPopup" type="popupOpened"/>  </af:popup> The Animation Styles  As before, we have a couple of CSS Styles which define the animation, I've put these into the skin in my case, and, as in the other articles, I've only defined the transitions for WebKit browsers (Chrome, Safari) at the moment. In this case, the fade is timed at 5 seconds in duration. .popupFadeReset {   opacity: 1; } .popupFadeAnimate {   opacity: 0;   -webkit-transition: opacity 5s ease-in-out; } As you can see here, we are achieving the fade by simply setting the CSS opacity property. The JavaScript The final part of the puzzle is, of course, the JavaScript, there are four functions, these are generic (apart from the Style names which, if you've changed above, you'll need to reflect here): The initial function invoked from the popupOpened event,  animateFadingPopup which starts a timer and provides the initial delay before we start to fade the popup. The function that applies the fade animation to the popup - initiatePopupFade. The callback function - closeFadedPopup used to reset the style class and correctly hide the popup so that it can be invoked again and again.   A utility function - findFadeContainer, which is responsible for locating the correct child component of the popup to actually apply the style to. Function - animateFadingPopup This function, as stated is the one hooked up to the popupOpened event via a clientListener. Because of when the code is called it does not actually matter how you launch the popup, or if the popup is re-used from multiple places. All usages will get the fade behavior. /**  * Client listener which will kick off the animation to fade the dialog and register  * a callback to correctly reset the popup once the animation is complete  * @param event  */ function animateFadingPopup(event) { var fadePopup = event.getSource();   var fadeCandidate = false;   //Ensure that the popup is initially Opaque   //This handles the situation where the user has dismissed   //the popup whilst it was in the process of fading   var fadeContainer = findFadeContainer(fadePopup);   if (fadeContainer != null) {     fadeCandidate = true;     fadeContainer.setStyleClass("popupFadeReset");   }   //Only continue if we can actually fade this popup   if (fadeCandidate) {   //See if a delay has been specified     var waitTimeSeconds = event.getSource().getProperty('preFadeDelay');     //Default to 5 seconds if not supplied     if (waitTimeSeconds == undefined) {     waitTimeSeconds = 5;     }     // Now call the fade after the specified time     var fadeFunction = function () {     initiatePopupFade(fadePopup);     };     var fadeDelayTimer = setTimeout(fadeFunction, (waitTimeSeconds * 1000));   } } The things to note about this function is the initial check that we have to do to ensure that the container is currently visible and reset it's style to ensure that it is.  This is to handle the situation where the popup has begun the fade, and yet the user has still explicitly dismissed the popup before it's complete and in doing so has prevented the callback function (described later) from executing. In this particular situation the initial display of the dialog will be (apparently) missing it's normal animation but at least it becomes visible to the user (and most users will probably not notice this difference in any case). You'll notice that the style that we apply to reset the  opacity - popupFadeReset, is not applied to the popup component itself but rather the dialog or panelWindow within it. More about that in the description of the next function findFadeContainer(). Finally, assuming that we have a suitable candidate for fading, a JavaScript  timer is started using the specified preFadeDelay wait time (or 5 seconds if that was not supplied). When this timer expires then the main animation styleclass will be applied using the initiatePopupFade() function Function - findFadeContainer As a component, the <af:popup> does not support styleClass attribute, so we can't apply the animation style directly.  Instead we have to look for the container within the popup which defines the window object that can have a style attached.  This is achieved by the following code: /**  * The thing we actually fade will be the only child  * of the popup assuming that this is a dialog or window  * @param popup  * @return the component, or null if this is not valid for fading  */ function findFadeContainer(popup) { var children = popup.getDescendantComponents();   var fadeContainer = children[0];   if (fadeContainer != undefined) {   var compType = fadeContainer.getComponentType();     if (compType == "oracle.adf.RichPanelWindow" || compType == "oracle.adf.RichDialog") {     return fadeContainer;     }   }   return null; }  So what we do here is to grab the first child component of the popup and check its type. Here I decided to limit the fade behaviour to only <af:dialog> and <af:panelWindow>. This was deliberate.  If  we apply the fade to say an <af:noteWindow> you would see the text inside the balloon fade, but the balloon itself would hang around until the fade animation was over and then hide.  It would of course be possible to make the code smarter to walk up the DOM tree to find the correct <div> to apply the style to in order to hide the whole balloon, however, that means that this JavaScript would then need to have knowledge of the generated DOM structure, something which may change from release to release, and certainly something to avoid. So, all in all, I think that this is an OK restriction and frankly it's windows and dialogs that I wanted to fade anyway, not balloons and menus. You could of course extend this technique and handle the other types should you really want to. One thing to note here is the selection of the first (children[0]) child of the popup. It does not matter if there are non-visible children such as clientListener before the <af:dialog> or <af:panelWindow> within the popup, they are not included in this array, so picking the first element in this way seems to be fine, no matter what the underlying ordering is within the JSF source.  If you wanted a super-robust version of the code you might want to iterate through the children array of the popup to check for the right type, again it's up to you.  Function -  initiatePopupFade  On to the actual fading. This is actually very simple and at it's heart, just the application of the popupFadeAnimate style to the correct component and then registering a callback to execute once the fade is done. /**  * Function which will kick off the animation to fade the dialog and register  * a callback to correctly reset the popup once the animation is complete  * @param popup the popup we are animating  */ function initiatePopupFade(popup) { //Only continue if the popup has not already been dismissed    if (popup.isPopupVisible()) {   //The skin styles that define the animation      var fadeoutAnimationStyle = "popupFadeAnimate";     var fadeAnimationResetStyle = "popupFadeReset";     var fadeContainer = findFadeContainer(popup);     if (fadeContainer != null) {     var fadeContainerReal = AdfAgent.AGENT.getElementById(fadeContainer.getClientId());       //Define the callback this will correctly reset the popup once it's disappeared       var fadeCallbackFunction = function (event) {       closeFadedPopup(popup, fadeContainer, fadeAnimationResetStyle);         event.target.removeEventListener("webkitTransitionEnd", fadeCallbackFunction);       };       //Initiate the fade       fadeContainer.setStyleClass(fadeoutAnimationStyle);       //Register the callback to execute once fade is done       fadeContainerReal.addEventListener("webkitTransitionEnd", fadeCallbackFunction, false);     }   } } I've added some extra checks here though. First of all we only start the whole process if the popup is still visible. It may be that the user has closed the popup before the delay timer has finished so there is no need to start animating in that case. Again we use the findFadeContainer() function to locate the correct component to apply the style to, and additionally we grab the DOM id that represents that container.  This physical ID is required for the registration of the callback function. The closeFadedPopup() call is then registered on the callback so as to correctly close the now transparent (but still there) popup. Function -  closeFadedPopup The final function just cleans things up: /**  * Callback function to correctly cancel and reset the style in the popup  * @param popup id of the popup so we can close it properly  * @param contatiner the window / dialog within the popup to actually style  * @param resetStyle the syle that sets the opacity back to solid  */ function closeFadedPopup(popup, container, resetStyle) { container.setStyleClass(resetStyle);   popup.cancel(); }  First of all we reset the style to make the popup contents opaque again and then we cancel the popup.  This will ensure that any of your user code that is waiting for a popup cancelled event will actually get the event, additionally if you have done this as a modal window / dialog it will ensure that the glasspane is dismissed and you can interact with the UI again.  What's Next? There are several ways in which this technique could be used, I've been working on a popup here, but you could apply the same approach to in-line messages. As this code (in the popup case) is generic it will make s pretty nice declarative component and maybe, if I get time, I'll look at constructing a formal Growl component using a combination of this technique, and active data push. Also, I'm sure the above code can be improved a little too.  Specifically things like registering a popup cancelled listener to handle the style reset so that we don't loose the subtle animation that takes place when the popup is opened in that situation where the user has closed the in-fade dialog.

  • Can't access internet with 32-bit browser(Chrome, FF, IE)! The 64-bit version of IE on Win 7 works f

    - by Sarveshwar
    I had installed Kaspersky AV 2010 two days ago. Everything was fine until I was not able to access the internet a few minutes back with the 32 bit browsers I have installed - Chrome, Firefox and the 32 bit IE. Then I see that utorrent is working fine!! So again I checked with the 64 bit IE and I could access the internet. I am currently using IE 64 bit to access superuser. Please help! I have uninstalled the KAV 2010. I thought that was the problem. Is this any virus or something? Also, whenever any browser (except IE 64), the screen freezes. Nothing except the browser works! And after the browser is closed, everything comes back to normal. Thanks!

  • PS/2 mouse works with Windows 7 32-bit but not recognised by 64-bit, What to do?

    - by Bogan
    Our USB mouse was stolen and a PS/2 OK_520 Mouse that works OK on my Medion PC, running Windows 7 32-bit, if plugged in before booting, is not recognised by Windows 7 64-bit on a Dell INSPIRONone_19T with a 19" Touch Screen. (It is a communal computer available to all residents.) A USB mouse works OK and the Update Driver option reports: 'driver is up to date'. Without the USB Mouse, Device Manager/Mice shows only the Touch Screen as a Mouse. The Add New Hardware option searches but shows nothing and the Troubleshooter says ' device possibly not recognised, alterations made to system, try again.' but it is still not recognised after repeated re-boots. The BIOS does not seem to have any option to enable a PS/2 Mouse. The Mouse is very old so maybe it is not 64-bit compatible, or there is no 64-bit driver for one, but how to get one if the device is not recognised?

  • Windows 7 x64 - Problem with 32-bit processes...

    - by Will A
    Hi All, Is it just me, or is Windows 7 x64 awfully unstable when it comes to 32-bit processes? If I ever find myself in a situation where a 32-bit process hangs or otherwise misbehaves, terminating the process (through e.g. task manager) seems to fail every time - there are no error messages or anything, it's just that the process refuses to terminate. Anyone else have the same problems running 32-bit applications on x64 Windows? Thanks, Will.

  • WiX: Prevent 32-bit installer from running on 64-bit Windows

    - by Tom the Junglist
    Hi everyone, Due to user confusion, our app requires separate installers for 32-bit and 64-bit versions of Windows. While the 32-bit installer runs fine on win64, it has the potential to create support headaches and we would like to prevent this from happening. I want to prevent the 32-bit MSI installer from running on 64-bit Windows machines. To that end I have the following condition: <Condition Message="You are attempting to run the 32-bit installer on a 64-bit version of Windows."> <![CDATA[Msix64 AND (NOT Win64)]]> </Condition> With the Win64 defined like this: <?if $(var.Platform) = "x64"?> <?define PlatformString = "64-bit"?> <?define Win64 ?> <?else?> <?define PlatformString = "32-bit"?> <?endif?> Thing is, I can't get this check to work right. Either it fires all the time, or none of the time. The goal is to check presence of the run-time msix64 variable against the compile-time Win64 variable and throw an error if these don't line up, but the logic is not working how I intend it to. Has anyone come up with a better solution? Thanks! Tom

  • Is it possible to reliably auto-decode user files to Unicode? [C#]

    - by NVRAM
    I have a web application that allows users to upload their content for processing. The processing engine expects UTF8 (and I'm composing XML from multiple users' files), so I need to ensure that I can properly decode the uploaded files. Since I'd be surprised if any of my users knew their files even were encoded, I have very little hope they'd be able to correctly specify the encoding (decoder) to use. And so, my application is left with task of detecting before decoding. This seems like such a universal problem, I'm surprised not to find either a framework capability or general recipe for the solution. Can it be I'm not searching with meaningful search terms? I've implemented BOM-aware detection (http://en.wikipedia.org/wiki/Byte_order_mark) but I'm not sure how often files will be uploaded w/o a BOM to indicate encoding, and this isn't useful for most non-UTF files. My questions boil down to: Is BOM-aware detection sufficient for the vast majority of files? In the case where BOM-detection fails, is it possible to try different decoders and determine if they are "valid"? (My attempts indicate the answer is "no.") Under what circumstances will a "valid" file fail with the C# encoder/decoder framework? Is there a repository anywhere that has a multitude of files with various encodings to use for testing? While I'm specifically asking about C#/.NET, I'd like to know the answer for Java, Python and other languages for the next time I have to do this. So far I've found: A "valid" UTF-16 file with Ctrl-S characters has caused encoding to UTF-8 to throw an exception (Illegal character?) (That was an XML encoding exception.) Decoding a valid UTF-16 file with UTF-8 succeeds but gives text with null characters. Huh? Currently, I only expect UTF-8, UTF-16 and probably ISO-8859-1 files, but I want the solution to be extensible if possible. My existing set of input files isn't nearly broad enough to uncover all the problems that will occur with live files. Although the files I'm trying to decode are "text" I think they are often created w/methods that leave garbage characters in the files. Hence "valid" files may not be "pure". Oh joy. Thanks.

  • python convert 12 bit image encoded in a string to 8 bit png

    - by ks
    I have a string that is read from a usb apogee camera that is a 12-bit grayscale image with the 12-bits each occupying the lowest 12 bits of 16-bits words. I want to create a 8-bit png from this string by ignoring the lowest 4 bits. I can convert it to a 16-bit image where the highest 4 bits are always zero using PIL with import Image imageStr is the image string imageSize is the image size img=Image.fromstring("I", imageSize, imageStr, "raw", "I;16", 0,1) img.save("MyImage.png", "PNG") Anyway I can do something similar to create a 8-bit image without completely unpacking the string doing arithmetic and making a new string?

    - by user137652
    All of our domain controllers (2) are Windows 2008 Standard 32 bit. We are trying to add a Standard 2008 R2 64 bit domain controller to the forest but for some reason during DCPROMO, we receive the following error: "to install a domain controller into this active directory forest,you must first prepare the forest using "adprep/forestprep" etc We went ahead an ran adprep /forestprep on our established domain controller and allowed time to replicate. When attempting to execute dcpromo again, we receive the same error. What gives?

  • Office 2007 32 bit to Office 2010 64 bit upgrade

    - by muhan
    I have Office 2007 32 bit installed. I want to install 2010 64 bit. I understand there is no direct upgrade. I have to uninstall and then install 2010. Is there a way to save all my settings, account info etc. before uninstalling? There was a settings migration wizard in Office 2003, it seems gone from 2007.

  • WPF Choppy Animation

    - by Chris Dunaway
    WPF Windows-XP SP3 I'm having a problem with a simple WPF animation. I use the following Xaml code (in XamlPad and also in a WPF project): <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:sys="clr-namespace:System;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" > <Border Name="MyBorder" BorderThickness="10" BorderBrush="Blue" CornerRadius="10" Background="DarkRed" > <Rectangle Name="MyRectangle" Margin="10" StrokeDashArray="2.0,1.0" StrokeThickness="10" RadiusX="10" RadiusY="10" Stroke="Black" StrokeDashOffset="0"> <Rectangle.Triggers> <EventTrigger RoutedEvent="Rectangle.Loaded"> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetName="MyRectangle" Storyboard.TargetProperty="StrokeDashOffset" From="0.0" To="3.0" Duration="0:0:1" RepeatBehavior="Forever" Timeline.DesiredFrameRate="30" /> </Storyboard> </BeginStoryboard> </EventTrigger> </Rectangle.Triggers> </Rectangle> </Border> </Page> It has the effect of causing the border to animate around the rectangle. After a fresh reboot of the machine, this animation is nice and smooth. However, I tend to leave my machine on all the time and after a period time elapses (I don't know how long), the animation starts stuttering and becomes choppy. I thought that it may be memory or resource issues, but after shutting down all other apps and any services that seem unnecessary, the stuttering still continues. However, after a system reboot, the animation is smooth again! I get the same symptoms in a WPF app or in XamlPad. In the case of the app, it doesn't seem to make any difference whether I run in the debugger or if I run the executable directly. I applied the patch at this link: http://support.microsoft.com/kb/981741 and I thought that it had taken care of the issue, but it seems not to have. I have seen some posts that might indicate that using transparency might affect animation, but as you can see, my xaml does not use transparency. Can anyone give me some suggestions on how to determine what the problem is? Are there any WPF diagnostic tools that might help? UPDATE: I have checked my video drivers and they are the latest version. (nVidia GeForce 8400 GS)
