  • MediaElement.Position behaviour and Windows Phone 7 issue

    - by RoguePlanetoid
    I have a problem, I have written a simple Media Player for Windows Phone 7 and can Play, Stop and control the Volume of a Video (loaded from a URI) however when I try to set the position, this causes the application to freeze. I have used both these lines, but either does not work: Player.Position = new TimeSpan(0, 0, 0, 0, (int)Position.Value); Player.Position = TimeSpan.FromSeconds((int)(Position.Value)); I do have this event handler: void Player_MediaOpened(object sender, RoutedEventArgs e) { Position.Maximum = Player.NaturalDuration.TimeSpan.TotalMilliseconds; } And have tried using the Seconds value, casting to Ints etc, however everytime I try to set the Position, the app freezes. The video otherwise plays normally - anyone know what the problem may be here?

  • Algorithm and data structure learning resources for dynamic programming

    - by Pranav
    Im learning dynamic programming now, and while I know the theory well, designing DP algorithms for new problems is still difficult. This is what i would really like now- A book or a website, which poses a problem which can be solved by dynamic programming. Also there is the solution with an explanation available, which i would like to see if i cant solve the problem even after butting my head at it for a few hours. Is there some resource that provides this sort of a thing for several categories of algorithms- like graph algorithms, dynamic programming, etc? P.S. I considered Topcoder, but the solutions there are not really appropriate for learning to implement efficient solutions.

  • Using PHP/MySQL with Google Maps

    - by Anders Kitson
    Hiya, I followed this tutorial below http://code.google.com/apis/maps/articles/phpsqlajax_v3.html#outputxml I ran into trouble, near then end, I am hoping someone else here has got this working and can help me discover my problem. Simply there are 4 steps to this tutorial Creating the Table Populating the Table Outputting XML with PHP Creating the Map I successfully have completed all the steps, however the outputted xml isn't read by the google map I created. The files are all on the same directory, and I didn't change any of the file names from the tutorial. The tutorial has a step to test if the php file called phpsqlajax_genxml.php is outputting the xml and I successfully tested it and it was. The problem is that the map isn't rendering the items I have in the database, that should be converted to xml for the map to read. Any help, or pointing me in the right direction would be much appreciated.

  • Silverlight standard loading animation does not get displayed.

    - by Anne Schuessler
    Can anybody enlighten me as to how the standard Silverlight loading animations (the swirling blue balls) are embedded in a Silverlight application and how they work? I currently don't see it although loading the xap takes long enough for the loading animation to be displayed. The problem is that I'm creating a xap dynamically and trying to write it to the Response Stream which might somehow interfere with the way most Silverlight applications work. So maybe there's something missing from the original aspx page or ClientBin that should be there that has been lost by accident. I haven't found any helpful information about how the loading animation is integrated into Silverlight that could help me debug the problem so far. Does anyone know what the animation needs to triggered as expected?

  • Use javac fork attribute with IBM JDK

    - by avjaz
    Hi - I have a large ant build that I'm working on, that is currently running out of memory. One ways I've read that can help mitigate this problem is to use javac fork="true" to run javac in a separate jvm. My problem is that I need to compile the project with the IBM JDK (this is not the JDK referenced by JAVA_HOME, and I would prefer it not to be). I tried setting the executable attribute of Ant's javac, to the path to IBM's javac but no joy (the project still won't compile). Ant's docs for the executable attribute state: Complete path to the javac executable to use in case of fork="yes". Defaults to the compiler of the Java version that is currently running Ant. Ignored if fork="no". Since Ant 1.6 this attribute can also be used to specify the path to the executable when using jikes, jvc, gcj or sj. Does anyone have any ideas? Thanks -

  • Suggestion for chkstk.asm stackoverfolw exception in C++ with Visual Studio 2010

    - by Gulshan
    I am working with an implementation of merge sort. I am doing C++ Visual Studio 2010. But when I took a array of 300000 integers for timing, it is showing an unhandled stackoverflow exception and taking me to a readonly file named "chkstk.asm". I reduced the size to 200000 and it worked. Again the same code worked with C-free 4 editor (mingw 2.95) without any problem while the size was 400000. Do you have any suggestion to get the code working in Visual Studio? May be the recursion in the mergesort is causing the problem.

  • Flot Pie Chart using Ajax, Php and MySql

    - by Neriza Almirol
    Good Day! Can you help me? I have a problem getting values from database. I want to control the legend. I've been googling the best approach for the pie chart, but still looking for the best answer for my problem. It's easy to query the data from the database, but I want to show it using the flot pie chart and I need it for statistic reports. From database, I need to get the percentage of Female and Male followers and separate it according to age groups. The data (dateOfbirth) is available from our database using facebook integration. Can you give me an example using Ajax, Php and MySql? Thank you! :) $.plot($("#graph_3"), graphData, { series: { pie: { show: true } }, grid: { hoverable: true, clickable: true } }); $("#graph_3").bind("plothover", pieHover); $("#graph_3").bind("plotclick", pieClick);

  • Get stacktrace from stuck python process

    - by piquadrat
    I have to run a legacy Zope2 website and have some grievance with it. The biggest issue is that, occasionally, it just locks up, running at 100% CPU load and not answering to requests anymore. While the problem isn't reproducible on a regular basis, one page containing 3 dynamic graphs triggers it sometimes, so I suspect some kind of race condition that leads to an endless loop or a stuck busywait. The problem is, I have not yet found a way to debug this thing. There's nothing in the Zope logs and nothing in the system logs. I tried the suggestions from this question to get a stacktrace, but the only signal that has any effect is SIGKILL. Is there another possibility to find out where exactly the process is when it gets stuck?

  • jqGrid footer cells "inherits" CSS from cells in the main grid

    - by Tore
    I have a footerrow in my jqGrid where I sum up the values in some of the columns. I set the footer using the 'footerData' function when the grid has completed loading. This requires the 'footerrow' property in the grid-options to be set to 'true'. Some of the columns which I don't sum up have CSS applied to them (to show some icons in the cells), which is set using the 'classes' property in the colModel API. The problem is that these CSS-classes are also applied to the cells in the footerrow. I don't want them applied there, but I don't know how to prevent them from being shown. I tried to use jQuery to remove the 'class' property from the td elements after calling the 'footerData' function. The problem is that while the grid is loading, the icons are flashed to the user. How can I prevent the CSS from being applied in the first place?

  • How do you fix an SVN 409 Conflict Error

    - by NerdStarGamer
    I used to use SVN 1.4 on OS X Leopard and everything was fine. A couple of weeks ago I installed a fresh copy of OS X 10.6. The version of SVN that comes with Snow Leopard is 1.6.5. I went ahead and built my own copy with 1.6.6. I'm using the built in apache server and just hosting repositories locally. Everything appeared to work fine until I actually tried to commit something. Everytime I try to commit a change, I get the following message: Transmitting file data .svn: Commit failed (details follow): svn: MERGE of '/svn/svn2': 409 Conflict (http://localhost) This happens with my old repositories, so I created a couple of new ones. Same deal. I also tried using the 1.6.5 version that comes with the system...same. Finally, I tried upgrading to the latest stable SVN (1.6.9) and still got the same problem. The Apache error logs the following for each failed commit: [Mon Mar 29 19:53:10 2010] [error] [client ::1] Could not MERGE resource "/svn/svn2/!svn/act/d399326f-c20f-424f-bb68-3bb40503b5b1" into "/svn/svn2".

I've tried to Google every variation I can think of for this problem, but the search results are pretty much useless. I'm not using TortoiseSVN or anything special and commits fail on a new repository, so I know it's not a problem with my old repos. Any help would be greatly appreciated.

  • tptp/profiling of web-application within eclipse - no data collectors available

    - by AJ
    Hi, I have a problem with tptp/profiling within eclipse. Because at first I had some very strange problems, I downloaded the “TPTP all-in-one package” (tptp.runtime.allInOne.win32.win32.x86-TPTP-4.6.2.zip) and added the stuff I need (Jboss-Tools, etc.) I am using Windows XP SP3, Java 6u20, Eclipse 3.5.2.(, jboss-4.2.3.GA-jdk6) In "Profile Configurations"/Tab "Monitor" I got “IWAT0435E An error occurred when connecting to the host” and in the “Profile on Server” Window in the tab Monitor I got only “pre-JRE 1.5“ as choice. After disabling an enabling the IAC in “Preferences”/”Agent Controller” that IWAT...-problem was gone but now I don't get anything in the “Profile on Server”/”Monitor” tab, but it says “[Monitor] The launch requires at least one data collector to be selected.” any ideas?

  • Delegate, BeginInvoke. EndInvoke - How to clean up multiple Async threat calls to the same delegate?

    - by Dan
    I've created a Delegate that I intend to call Async. Module Level Delegate Sub GetPartListDataFromServer(ByVal dvOriginal As DataView, ByVal ProgramID As Integer) Dim dlgGetPartList As GetPartListDataFromServer The following code I use in a method Dim dlgGetPartList As New GetPartListDataFromServer(AddressOf AsyncThreadMethod_GetPartListDataFromServer) dlgGetPartList.BeginInvoke(ucboPart.DataSource, ucboProgram.Value, AddressOf AsyncCallback_GetPartListDataFromServer, Nothing) The method runs and does what it needs to The Asyn callback is fired upon completion where I do an EndInvoke Sub AsyncCallback_GetPartListDataFromServer(ByVal ar As IAsyncResult) dlgGetPartList.EndInvoke(Nothing) End Sub It works as long as the method that starts the BeginInvoke on the delegate only ever runs while there is not a BeginInvoke/Thread operation already running. Problem is that the a new thread could be invoked while another thread on the delegate is still running and hasnt yet been EndInvoke'd. The program needs to be able to have the delegate run in more than one instance at a time if necessary and they all need to complete and have EndInvoke called. Once I start another BeginInvoke I lose the reference to the first BeginInvoke so I am unable to clean up the new thread with an EndInvoke. What is a clean solution and best practice to overcome this problem?

  • Ruby on Rails Mysterious Javascript Alert box with cookie information

    - by conorgil
    I have a problem in a Ruby on Rails app that I am working on. I have been working on the app for months and I have never had this problem before and after a bit of Google searches I think that somehow someone is trying to steal cookies with javascript. When I click on the link I get an alert box titled "the page at www.napkinboard.com says:" and contains the following message: __utmz=217223433.1270652009.59.3.utmcsr=localhost:3000|utmccn=(referral)|utmcmd=referral|utmcct=/; __utma=217223433.2133018314.1265749085.1271097412.1271125626.63; __utmc=217223433; __utmb=217223433.11.10.1271125626 I checked the database and all data associated with this 'food_item' looks completely normal and does not contain any javascript at all. How did this suddenly happen and how can I stop it? I appreciate any help. Thanks.

  • CCSprite following a sequence of CGPoints

    - by pgb
    I'm developing a line drawing game, similar to Flight Control, Harbor Master, and others in the appstore, using Cocos2D. For this game, I need a CCSprite to follow a line that the user has drawn. I'm storing a sequence of CGPoint structs in an NSArray, based on the points I get in the touchesBegin and touchesMoved messages. I now have the problem of how to make my sprite follow them. I have a tick method, that is called at the framerate speed. In that tick method, based on the speed and current position of the sprite, I need to calculate its next position. Is there any standard way to achieve this? My current approach is calculate the line between the last "reference point" and the next one, and calculate the next point in that line. The problem I have is when the sprite "turns" (moves from one segment of the line to another). Any hint will be greatly appreciated.

  • IronPython and Nodebox in C#

    - by proxylittle
    My plan: I'm trying to setup my C# project to communicate with Nodebox to call a certain function which populates a graph and draws it in a new window. Current situation: [fixed... see Update2] I have already included all python-modules needed, but im still getting a Library 'GL' not found it seems that the pyglet module needs a reference to GL/gl.h, but can't find it due to IronPython behaviour. Requirement: The project needs to stay as small as possible without installing new packages. Thats why i have copied all my modules into the project-folder and would like to keep it that or a similar way. My question: Is there a certain workaround for my problem or a fix for the library-folder missmatch. Have read some articles about Tao-Opengl and OpenTK but can't find a good solution. Update1: Updated my sourcecode with a small pyglet window-rendering example. Problem is in pyglet and referenced c-Objects. How do i include them in my c# project to be called? No idea so far... experimenting alittle now. Keeping you updated. SampleCode C#: ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(null); ScriptRuntime runtime = new ScriptRuntime(setup); ScriptEngine engine = Python.GetEngine(runtime); ScriptSource source = engine.CreateScriptSourceFromFile("test.py"); ScriptScope scope = engine.CreateScope(); source.Execute(scope); SampleCode Python (test.py): from nodebox.graphics import * from nodebox.graphics.physics import Vector, Boid, Flock, Obstacle flock = Flock(50, x=-50, y=-50, width=700, height=400) flock.sight(80) def draw(canvas): canvas.clear() flock.update(separation=0.4, cohesion=0.6, alignment=0.1, teleport=True) for boid in flock: push() translate(boid.x, boid.y) scale(0.5 + boid.depth) rotate(boid.heading) arrow(0, 0, 15) pop() canvas.size = 600, 300 def main(canvas): canvas.run(draw) Update2: Line 139 [pyglet/lib.py] sys.platform is not win32... there was the error. Fixed it by just using the line: from pyglet.gl.lib_wgl import link_GL, link_GLU, link_WGL Now the following Error: 'module' object has no attribute '_getframe' Kind of a pain to fix it. Updating with results... Update3: Fixed by adding following line right after first line in C#-Code: setup.Options["Frames"] = true; Current Problem: No module named unicodedata, but in Python26/DLLs is only a *.pyd file`. So.. how do i implement it now?!

  • Send parameters in order in HTTPService

    - by Suraj Chandran
    I am trying to work with a simple HTTPService. The problem is that my webservice is conscious of the order of arguments it gets. I will tell the problem with an example: var service:HTTPService = new HTTPService(); var params:Object = new Object(); params.rows = 0; params.facet = "true"; service.send(params); Note that in the above code I have mentioned the parameter rows before facet, but the url I recieve is facet=true&rows=0. So I recieve the argument rows before facet and hence my webservice does not work. I figured out that the contents of array is always sent in alphabetical order, which I dont want. Is there any way I can achieve explict ordering of parameters sent? Note that I am not in power of changing the logic of webservice(its basically a RPC service supporting both desktop and web client). Thanks.

  • "Quoted-printable line longer than 76 chars" warning when sending HTML E-Mail

    - by Chris Roberts
    Hi, I have written some code in my VB.NET application to send an HTML e-mail (in this case, a lost password reminder). When I test the e-mail, it gets eaten by my spam filter. One of the things that it's scoring badly on is because of the following problem: MIME_QP_LONG_LINE RAW: Quoted-printable line longer than 76 chars I've been through the source of the e-mail, and I've broken each line longer than 76 characters into two lines with a CR+LF in between, but that hasn't fixed the problem. Can anyone point me in the right direction? Thanks!

  • How to setup matlab for parallel processing on Amazon EC2?

    - by JohnIdol
    I just setup a Extra Large Heavy Computation EC2 instance to throw it at my Genetic Algorithms problem, hoping to speed up things. This instance has 8 Intel Xeon processors (around 2.4Ghz each) and 7 Gigs of RAM. On my machine I have an Intel Core Duo, and matlab is able to work with my two cores just fine. On the EC2 instance though, matlab only is capable of detecting 1 out of 8 processors. Obviously the difference is that I have my 2 cores on a single processor, while the EC2 instance has 8 distinct processors. My question is, how do I get matlab to work with those 8 processors? I found this paper, but it seems related to setting up matlab with multiple EC2 instances, which is not my problem. Any help appreciated!

  • Assinging a GD reference to a new variable fails to copy

    - by Stomped
    This is a contrived example, but it illustrates my problem much more concisely then the code I'm using - and I've tested this and it exhibits the problem: $image = imagecreatefromjpeg('test.jpg'); $copy_of_image = $image; // The important bit imagedestroy($image); header('Content-type: image/jpeg'); imagejpeg($copy_of_image); Now, my expectation is that $copy_of_image is exactly that, but when I run this, it fails, printing out the URL of the script of all things. Comment out the imagedestroy() and it works just fine. a var_dump of $image provides: resource(3) of type (gd) So why can't I copy this? Apparently the assignment $copy_of_image = $image is creating a reference rather then a copy - is there a way to prevent that?

  • flash dynamic textfield, multiline and wordwrap acting funky.

    - by pfunc
    I have this weird thing happening with flash and a dynamic textfield. Basically, someone rolls over a marker on a map, and a tooltip pops up with a dynamic textfield. The textfield is set to multiline=true and wordwrap = true, and I defined a specific width of 160 pixels. The problem is, some of my text is jumping to the next line, some of it is just getting cut off. So if I have a line like "The Cat Jumped Over the Box", On one line I will see "The Cat Jumped" and on the next line I would see "the Box". It looks like it is masking out the "over" line and not pushing it to the next line. It's not doing this for everything, just some longer lines. This is a really weird bug and I have tried for 8 hours to get this fixed. Has anyone ran into this problem before?

  • svn merge - moved repository to a different server, and now getting 'has different repository root'

    - by HorusKol
    This is kind of similar to http://stackoverflow.com/questions/1601021/subversion-merge-has-different-repository-root-than - but appears to be a very different cause (especially as the answer for that question didn't resolve my problem). A while back, we swapped out the server where our SVN repositories are located - but we've been using an alias so that the old server name points to the new server. I've been getting in the habit where I will use the new server name wherever I checkout new working copies - but we having made changes to most of the current working copies as they are live websites. Until now, this hasn't been a problem - except that this morning I merged in some changes from my development branch to a working copy I have of the release version and I got the message "file has different repository root" and the merge stops dead. I know this is because I'm using the new server name when the development branch was updated via the old server name - but is there a simple way to fix this? Or if not a simple way - is there a well-documented way to fix this?

  • How does ListView.ItemCollection.Contains() work?

    - by Inno
    Hi everyone, I'm copying ListViewItems from one ListView to another, sth. like: foreach (ListViewItem item in usersListView.SelectedItems) { selectedUsersListView.Items.Add((ListViewItem)item.Clone()); } If I want to use ListView.ItemCollection.Contains() to determine if an item was already copied I always get false: foreach (ListViewItem item in usersListView.SelectedItems) { if (!selectedUsersListView.Items.Contains(item) { // always !false selectedUsersListView.Items.Add((ListViewItem)item.Clone()); } } I did the following to solve my problem: foreach (ListViewItem item in usersListView.SelectedItems) { ListViewItem newItem = (ListViewItem)item.Clone(); newItem.Name = newItem.Text; if (!selectedUsersListView.Items.ContainsKey(newItem.Name) { // this works selectedUsersListView.Items.Add(newItem); } } So, it's ok that this solves my problem but I still have no idea why ListView.ItemCollection.Contains() doesn't work... How does ListView.ItemCollection.Contains() identify if an item already exists? How do ListViewItems have to be initialised that ListView.ItemCollection.Contains() (not ListView.ItemCollection.ContainsKey()) is able to identify them?

  • SQlite: Column format for unix timestamp; Integer types

    - by SF.
    Original problem: What is the right column format for a unix timestamp? The net is full of confusion: some posts claim SQLite has no unsigned types - either whatsoever, or with exception of the 64bit int type (but there are (counter-)examples that invoke UNSIGNED INTEGER). The data types page mentions it only in a bigint example. It also claims there is a 6-byte integer but doesn't give a name for it. Of course standard INTEGER being 4-byte signed signed stores unix timestamps as negative numbers. I've heard that some systems return 64-bit timestamps too. OTOH I'm not too fond of wasting 4 bytes to store 1 extra bit (top bit of timestamp), and even if I have to pick a bigger data format, I'd rather go for the 6-byte one. I've even seen a post that claims SQLite unix timestamp is of type REAL... Complete problem: Could someone please clarify that mess?
