  • How would a php or java client authenticate if I'm using WCF w/ forms auth?

    - by Toran Billups
    I have a generic proof of concept WCF service that is using forms authentication to secure access. All works great when my client is .NET (vb code below) Dim client As SupplierServiceClient = New SupplierServiceClient() client.ClientCredentials.UserName.UserName = "[email protected]" client.ClientCredentials.UserName.Password = "password" Dim SupplierList As List(Of Supplier) = client.GetSuppliers() but as I want this to interop w/ anyone who can do SOAP 1.1/1.2 - how would a PHP or Java client connect? My WCF web.config is listed below (fyi) <system.serviceModel> <services> <service name="SampleApplicationWCF.Library.SupplierService" behaviorConfiguration="NorthwindBehavior"> <endpoint address="" name="wsHttpSupplierService" contract="SampleApplicationWCF.Library.ISupplierService" binding="wsHttpBinding" bindingConfiguration="wsHttp"/> <endpoint address="https://server/SampleApplicationWCF/SupplierService.svc/Basic" name="basicHttpSupplierService" contract="SampleApplicationWCF.Library.ISupplierService" binding="basicHttpBinding" bindingConfiguration="basicHttp"/> <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex"/> </service> </services> <bindings> <wsHttpBinding> <binding name="wsHttp"> <security mode="TransportWithMessageCredential"> <transport/> <message clientCredentialType="UserName" negotiateServiceCredential="false" establishSecurityContext="true"/> </security> </binding> </wsHttpBinding> <basicHttpBinding> <binding name="basicHttp"> <security mode="TransportWithMessageCredential"> <transport/> <message clientCredentialType="UserName"/> </security> </binding> </basicHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="NorthwindBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceAuthorization principalPermissionMode="UseAspNetRoles"/> <serviceCredentials> <userNameAuthentication userNamePasswordValidationMode="MembershipProvider"/> </serviceCredentials> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel>

  • A shortest path problem with superheroes and intergalactic journeys

    - by Dman
    You are a super-hero in the year 2222 and you are faced with this great challenge: starting from your home planet Ilop you must try to reach Acinhet or else your planet will be destroyed by evil green little monsters. To do this you are given a map of the universe: there are N planets and M inter-planetary connections ( bidirectional ) that bind these planets. Each connection requires a certain time and a certain amount of fuel in order for you to cover the connection from one planet to another. The total time spent going from one planet to another is obtained by multiplying the time past to cover each connection between all the planets you go through. There are some "key planets", that allow you to refuel if you arrive on those certain "key planets". A "key planet" is the planet with the property that if it disappears the road between at least two planets would be lost.(In the example posted below with the input/output files such a "key planet" is 2 because without it the road to 7 would be lost) When you start your mission you are given the possibility of choosing between K ships each with its own maximum fuel capacity. The goal is to find the SHORTEST TIME CONSUMING path but also choose the ship with the minimum fuel capacity that can cover that shortest path(this means that if more ships can cover the shortest path you choose the one with the minimum fuel capacity). Because the minimum time can be a rather large number (over long long int) you are asked to provide only the last 6 digits of the number. For a better understanding of the task, here is an example of input/output files: INPUT: mission.in 7 8 6 1 4 6 5 9 8 7 10 1 2 7 8 1 4 14 9 1 5 3 1 2 3 1 2 2 7 7 1 3 4 2 2 4 6 4 1 5 6 3 7 On the first line (in order): N M K On the second line :the number for the starting planet and the finishing planet On the third line :K numbers that represent the capacities of the ships you can choose from Then you have M lines, all of them have the same structure: Xi Yi Ti Fi-which means that there is a connection between Xi and Yi and you can cover the distance from Xi to Yi in Ti time and with a Fi fuel consumption. OUTPUT:mission.out 000014 8 1 2 3 4 On the first line:the minimum time and fuel consumption; On the second line :the path Restrictions: 2 = N = 1 000 1 = M = 30 000 1 = K = 10 000 Any suggestions or ideas of how this problem might be solved would be most welcomed.

  • Favorite Visual Studio keyboard remappings?

    - by hoytster
    Stack Overflow has covered favorite short-cuts and add-ins, optimizations and preferences -- great topics all. If this one has been covered, I can't find it -- so thanks in advance for the link. What are your favorite Visual Studio keyboard remappings? Mine are motivated by the fact that I'm a touch-typist. Mouse, function keys, arrow keys, Home, End -- bleh. These are commands I do all day every day, so I've remapped them to sequences I can execute without moving my hands from the home row. The command that is remapped in Tools = Customize = [Keyboard] is shown in parentheses. I'm 100% positive that there are better remappings than these, so please post yours! Please include the command; oft times, figuring it out is a challenge. -- Hoytster Running the app and operating the debugger Ctrl+Q + Ctrl+R Run the application, in debug mode (Debug.Start) Ctrl+Q + Ctrl+Q Quit (stop) the application (Debug.StopDebugging) Ctrl+T Toggle a breakpoint at the current line (Debug.ToggleBreakpoint) Ctrl+K + Ctrl+I Step Into the method (Debug.StepInto) Ctrl+K + Ctrl+O Step Out of the method (Debug.StepOut) Ctrl+N Step over the method to the Next statement (Debug.StepOver) Ctrl+K + Ctrl+C Run the code, stopping at the Cursor position (Debug.RunToCursor) Ctrl+K + Ctrl+E Set then next statement to Execute (Debug.SetNextStatement) Navigating the code Ctrl+S Move a character LEFT (Edit.CharLeft) Ctrl+D Move a character RIGHT (Edit.CharRight) Ctrl+Q + Ctrl+S Move to the LEFT END of the current line (Edit.LineStart) Ctrl+Q + Ctrl+D Move to the RIGHT END of the current line (Edit.LineEnd) Ctrl+E Move a line UP (Edit.LineUp) Ctrl+X Move a line DOWN (Edit.LineDown) Ctrl+K + Ctrl+K Toggle (add or remove) bookmark (Edit.ToggleBookmark) Ctrl+K + Ctrl+N Move to the NEXT bookmark (Edit.NextBookmark) Ctrl+K + Ctrl+P Move to the PREVIOUS bookmark (Edit.PreviousBookmark) Ctrl+Q + Ctrl+W Save all modified Windows (File.SaveAll) Ctrl+L Find the NEXT instance of the search string (Edit.FindNext) Ctrl+K + Ctrl+L Find the PREVIOUS instance of the search string (Edit.FindPrevious) Ctrl+Q + Ctrl+L Drop down the list of open files (Window.ShowEzMDIFileList) The last sequence is like clicking the downward-facing triangle in the upper-right corner of the code editor window.

  • How can I edit an entity in MVC4 with EF5 which has a unique constraint?

    - by Yoeri
    [HttpPost] public ActionResult Edit(Car car) { if (ModelState.IsValid) { db.Entry(car).State = EntityState.Modified; db.SaveChanges(); return RedirectToAction("Index"); } return View(car); } This is a controller method scaffolded by MCV 4 My "car" entity has a unique field: LicensePlate. I have custom validation on my Entity: Validation: public partial class Car { partial void ValidateObject(ref List<ValidationResult> validationResults) { using (var db = new GarageIncEntities()) { if (db.Cars.Any(c => c.LicensePlate.Equals(this.LicensePlate))) { validationResults.Add( new ValidationResult("This licenseplate already exists.", new string[]{"LicensePlate"})); } } } } should it be usefull, my car entity: public partial class Car:IValidatableObject { public int Id { get; set; } public string Color { get; set; } public int Weight { get; set; } public decimal Price { get; set; } public string LicensePlate { get; set; } public System.DateTime DateOfSale { get; set; } public int Type_Id { get; set; } public int Fuel_Id { get; set; } public virtual CarType Type { get; set; } public virtual Fuel Fuel { get; set; } public IEnumerable<ValidationResult> Validate(ValidationContext validationContext) { var result = new List<ValidationResult>(); ValidateObject(ref result); return result; } partial void ValidateObject(ref List<ValidationResult> validationResults); } QUESTION: Everytime I edit a car, it raises an error: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details. The error is the one raised by my validation, saying it can't edit because there is already a car with that license plate. If anyone could point me in the right direction to fix this, that would be great! I searched but couldn't find anything, so even related posts are welcome!

  • How can I make these images download on a separate thread?

    - by Andy Barlow
    I have the following code running on my Android device. It works great and displays my list items wonderfully. It's also clever in the fact it only downloads the data when it's needed by the ArrayAdapter. However, whilst the download of the thumbnail is occurring, the entire list stalls and you cannot scroll until it's finished downloading. Is there any way of threading this so it'll still scroll happily, maybe show a place holder for the downloading image, finish the download, and then show? Any help with this would be really appreciated. private class CatalogAdapter extends ArrayAdapter<SingleQueueResult> { private ArrayList<SingleQueueResult> items; //Must research what this actually does! public CatalogAdapter(Context context, int textViewResourceId, ArrayList<SingleQueueResult> items) { super(context, textViewResourceId, items); this.items = items; } /** This overrides the getview of the ArrayAdapter. It should send back our new custom rows for the list */ @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.mylists_rows, null); } final SingleQueueResult result = items.get(position); // Sets the text inside the rows as they are scrolled by! if (result != null) { TextView title = (TextView)v.findViewById(R.id.mylist_title); TextView format = (TextView)v.findViewById(R.id.mylist_format); title.setText(result.getTitle()); format.setText(result.getThumbnail()); // Download Images ImageView myImageView = (ImageView)v.findViewById(R.id.mylist_thumbnail); downloadImage(result.getThumbnail(), myImageView); } return v; } } // This should run in a seperate thread public void downloadImage(String imageUrl, ImageView myImageView) { try { url = new URL(imageUrl); URLConnection conn = url.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is); Bitmap bm = BitmapFactory.decodeStream(bis); bis.close(); is.close(); myImageView.setImageBitmap(bm); } catch (IOException e) { /* Reset to Default image on any error. */ //this.myImageView.setImageDrawable(getResources().getDrawable(R.drawable.default)); } }

  • PHP Processes reaching limit along with FastCGI timeouts

    - by Constant M
    I have a problem similar to http://stackoverflow.com/questions/1168384/how-to-troubleshoot-php-processes, but with a twist. We have a couple of managed servers that recently migrated to FastCGI. Since then we've been having problems. We have a content management system at a central place that we manage all our sites with. All the sites run on the same managed server. So basically its one PHP script that generates pages on the same server. The catch comes in where it works perfectly on some, and gives FCGI timeout errors on others. At the same time our support is saying that the PHP processes heap up to their limit and then causes Apache to stop working. I'm convinced this is a fault on their side, but would like to get my side clean too. Anyway have any suggestions where I can start looking for what's going wrong? I know it's a really broad question, but any help or pointers would be great.

  • Performance of looping over an Unboxed array in Haskell

    - by Joey Adams
    First of all, it's great. However, I came across a situation where my benchmarks turned up weird results. I am new to Haskell, and this is first time I've gotten my hands dirty with mutable arrays and Monads. The code below is based on this example. I wrote a generic monadic for function that takes numbers and a step function rather than a range (like forM_ does). I compared using my generic for function (Loop A) against embedding an equivalent recursive function (Loop B). Having Loop A is noticeably faster than having Loop B. Weirder, having both Loop A and B together is faster than having Loop B by itself (but slightly slower than Loop A by itself). Some possible explanations I can think of for the discrepancies. Note that these are just guesses: Something I haven't learned yet about how Haskell extracts results from monadic functions. Loop B faults the array in a less cache efficient manner than Loop A. Why? I made a dumb mistake; Loop A and Loop B are actually different. Note that in all 3 cases of having either or both Loop A and Loop B, the program produces the same output. Here is the code. I tested it with ghc -O2 for.hs using GHC version 6.10.4 . import Control.Monad import Control.Monad.ST import Data.Array.IArray import Data.Array.MArray import Data.Array.ST import Data.Array.Unboxed for :: (Num a, Ord a, Monad m) => a -> a -> (a -> a) -> (a -> m b) -> m () for start end step f = loop start where loop i | i <= end = do f i loop (step i) | otherwise = return () primesToNA :: Int -> UArray Int Bool primesToNA n = runSTUArray $ do a <- newArray (2,n) True :: ST s (STUArray s Int Bool) let sr = floor . (sqrt::Double->Double) . fromIntegral $ n+1 -- Loop A for 4 n (+ 2) $ \j -> writeArray a j False -- Loop B let f i | i <= n = do writeArray a i False f (i+2) | otherwise = return () in f 4 forM_ [3,5..sr] $ \i -> do si <- readArray a i when si $ forM_ [i*i,i*i+i+i..n] $ \j -> writeArray a j False return a primesTo :: Int -> [Int] primesTo n = [i | (i,p) <- assocs . primesToNA $ n, p] main = print $ primesTo 30000000

  • Image Hover-HTML CSS

    - by LostSchemer
    I am having trouble creating a different image to appear when you place your curser over the original image. Heres my code without the rest of my listed buttons: <nav class="buttons"> <ul> <li class="left"> <a class="home" href="www.google.com"> <img src="img/Home_2.png"></a></li> </ul> </nav> Css: .buttons img{width: 190px; margin:0px; padding:0px; margin:0 auto; margin-top:55px;} .buttons ul{list-style-type: none; margin:0px; padding:0px} .left{float:left} .home:hover {background: url(../img/Home_crack.PNG)} Any suggestions? EDIT: Okay great suggestions, however when I hover over the "home button" now the stuff in the float tweeks out. Heres the code with the full float properties: HTML: <nav class="buttons"> <ul> <li class="left"> <a class="home" href="www.google.com"> <img src="img/Home_2.png"></a></li> <li class="left"> <a href="www.google.com" class="menu"> <img src="img/Menu_2.png"></a></li> <li class="right"> <a href="www.google.com" class="about"> <img src="img/About_2.png"></a></li> <li class="right"> <a href="www.google.com" class="contact"> <img src="img/Contact_2.png"></a></li> </ul> </nav> CSS: .buttons img{width: 190px; margin:0px; padding:0px; margin:0 auto; margin-top:55px;} .buttons ul{list-style-type: none; margin:0px; padding:0px} .left{float:left} .home:hover img{display:none} .home:hover {background: url(../img/Home_crack.PNG);} .right{float:right} Basically i wanted to separate 4 buttons.... one in the left float and one in the right float, then on the hover, the buttons would change to a different image....With the new img{display:none} the left float rapidly flashes.

  • help merging perl code routines together for file processing

    - by jdamae
    I need some perl help in putting these (2) processes/code to work together. I was able to get them working individually to test, but I need help bringing them together especially with using the loop constructs. I'm not sure if I should go with foreach..anyways the code is below. Also, any best practices would be great too as I'm learning this language. Thanks for your help. Here's the process flow I am looking for: -read a directory -look for a particular file -use the file name to strip out some key information to create a newly processed file -process the input file -create the newly processed file for each input file read (if i read in 10, I create 10 new files) Sample Recs: col1,col2,col3,col4,col5 [email protected],[email protected],8,2009-09-24 21:00:46,1 [email protected],[email protected],16,2007-08-18 22:53:12,33 [email protected],[email protected],16,2007-08-18 23:41:23,33 Here's my test code: Target Filetype: `/backups/test/foo101.name.aue-foo_p002.20110124.csv` Part 1: my $target_dir = "/backups/test/"; opendir my $dh, $target_dir or die "can't opendir $target_dir: $!"; while (defined(my $file = readdir($dh))) { next if ($file =~ /^\.+$/); #Get filename attributes if ($file =~ /^foo(\d{3})\.name\.(\w{3})-foo_p(\d{1,4})\.\d+.csv$/) { print "$1\n"; print "$2\n"; print "$3\n"; } print "$file\n"; } Part 2: use strict; use Digest::MD5 qw(md5_hex); #Create new file open (NEWFILE, ">/backups/processed/foo$1.name.$2-foo_p$3.out") || die "cannot create file"; my $data = ''; my $line1 = <>; chomp $line1; my @heading = split /,/, $line1; my ($sep1, $sep2, $eorec) = ( "^A", "^E", "^D"); while (<>) { my $digest = md5_hex($data); chomp; my (@values) = split /,/; my $extra = "__mykey__$sep1$digest$sep2" ; $extra .= "$heading[$_]$sep1$values[$_]$sep2" for (0..scalar(@values)); $data .= "$extra$eorec"; print NEWFILE "$data"; } #print $data; close (NEWFILE);

  • How come my South migrations doesn't work for Django?

    - by TIMEX
    First, I create my database. create database mydb; I add "south" to installed Apps. Then, I go to this tutorial: http://south.aeracode.org/docs/tutorial/part1.html The tutorial tells me to do this: $ py manage.py schemamigration wall --initial >>> Created 0001_initial.py. You can now apply this migration with: ./manage.py migrate wall Great, now I migrate. $ py manage.py migrate wall But it gives me this error... django.db.utils.DatabaseError: (1146, "Table 'fable.south_migrationhistory' doesn't exist") So I use Google (which never works. hence my 870 questions asked on Stackoverflow), and I get this page: http://groups.google.com/group/south-users/browse_thread/thread/d4c83f821dd2ca1c Alright, so I follow that instructions >> Drop database mydb; >> Create database mydb; $ rm -rf ./wall/migrations $ py manage.py syncdb But when I run syncdb, Django creates a bunch of tables. Yes, it creates the south_migrationhistory table, but it also creates my app's tables. Synced: > django.contrib.admin > django.contrib.auth > django.contrib.contenttypes > django.contrib.sessions > django.contrib.sites > django.contrib.messages > south > fable.notification > pagination > timezones > fable.wall > mediasync > staticfiles > debug_toolbar Not synced (use migrations): - (use ./manage.py migrate to migrate these) Cool....now it tells me to migrate these. So, I do this: $ py manage.py migrate wall The app 'wall' does not appear to use migrations. Alright, so fine. I'll add wall to initial migrations. $ py manage.py schemamigration wall --initial Then I migrate: $ py manage.py migrate wall You know what? It gives me this BS: _mysql_exceptions.OperationalError: (1050, "Table 'wall_content' already exists") Sorry, this is really pissing me off. Can someone help ? thanks. How do I get South to work and sync correctly with everything?

  • Replace a div content with PHP

    - by Zakaria
    hi everybody, yesterday, I posted a question about "Hom to change a DIV id with a php function" and someone found the right answer with a regular expression. The problem is that I wanted to use this answer to aplly the method on other same problems. But, as I'm very bad at regular expressions, I couldn't. So the problem is that I upload some videos with FCKEditor and put the video script in my database and the result is like that: <div id="player959093-parent" style="text-align: center;float: left;"> <div style="border-style: none; height: 160px; width: 270px; overflow: hidden; background-color: rgb(220, 220, 220); background-image: url(http://localhost/fckeditor/editor/plugins/flvPlayer/flvPlayer.gif); background-repeat:no-repeat; background-position:center;"><script src="http://localhost/fckeditor/editor/plugins/flvPlayer/swfobject.js" type="text/javascript"></script> <div id="player959093"><a href="http://www.macromedia.com/go/getflashplayer">Get the Flash Player</a> to see this player. <div id="player959093-config" style="display: none;visibility: hidden;width: 0px;height:0px;overflow: hidden;">url=/editeur/images/flash/FOO.flv width=270 height=160 loop=false play=false downloadable=false fullscreen=true displayNavigation=true displayDigits=true align=left dispPlaylist=none playlistThumbs=false</div> </div> <script type="text/javascript"> var s1 = new SWFObject("http://localhost/editeur/javascript/fckeditor/editor/plugins/flvPlayer/mediaplayer.swf","single","270","160","7"); s1.addVariable("width","270"); s1.addVariable("height","160"); s1.addVariable("autostart","false"); s1.addVariable("file","/editeur/images/flash/FOO.flv"); s1.addVariable("repeat","false"); s1.addVariable("image",""); s1.addVariable("showdownload","false"); s1.addVariable("link","/editeur/images/flash/FOO.flv"); s1.addParam("allowfullscreen","true"); s1.addVariable("showdigits","true"); s1.addVariable("shownavigation","true"); s1.addVariable("logo",""); s1.write("player959093"); </script></div> </div> When I echo this content once in my PHP page, It works great. More than once, the videos doesn't appear. Which is obvious because of the unique ID. As you can see, the content has these ids: div id="player959093-parent" div id="player959093" div id="player959093-config s1.write("player959093"); So my question is: Is there a function that can replace the string "player959093" or concatenate it with some other string to resolve the display problem? Thank you very much, Regards.

  • bottom uicomponent does not receive mouse events

    - by firemonkey
    HI, I am sure this is very basic, however I am not able to find the solution. I have a base ShapeContainer(UIComponent). I add a uicomponent which has mouse down listener to ShapeContainer. the listener works great. When I add a simple sprite(draw square) on the ShapeContainer, The listener does not work any more. In the code, if I comment below lines, The event listener works fine. var square:Sprite = new Sprite(); square.graphics.lineStyle(4,0x00FF00); square.graphics.drawRect(0,0,20,20); square.mouseEnabled=false; shapeContainer.addChildAt(square,1); I have tried few things like, mouseenabled=false on top sprite. also tried to add addChildAt but non of them did any help. How can I draw a shape and also have the event listener work. enter code here protected function application1_creationCompleteHandler(event:FlexEvent):void { var shapeContainer:UIComponent = new UIComponent(); shapeContainer.x=100; shapeContainer.y=100; shapeContainer.width=200; shapeContainer.height=200; rawChildren.addChild(shapeContainer); var EventListenerShape:UIComponent = new UIComponent(); EventListenerShape.x=100; EventListenerShape.y=100; EventListenerShape.width=200;a EventListenerShape.height=200; EventListenerShape.graphics.clear(); EventListenerShape.graphics.beginFill(0xf1f1f1, 0.1); EventListenerShape.graphics.drawRoundRect(0, 0, 200, 200, 10, 10); EventListenerShape.alpha = 0; EventListenerShape.graphics.endFill(); EventListenerShape.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownfunc); shapeContainer.addChild(EventListenerShape); var square:Sprite = new Sprite(); square.graphics.lineStyle(4,0x00FF00); square.graphics.drawRect(0,0,20,20); square.mouseEnabled=false; shapeContainer.addChildAt(square,1); } private function mouseDownfunc(e:MouseEvent){ trace("mouse Down **"); }    ]]> </mx:Script> <mx:Canvas id="uic" width="100%" height="100%" backgroundColor="0xFFFFFF"> </mx:Canvas>

  • JQuery Menu plugins under ASP.NET MVC seem to only work in Chrome, but not in IE & FireFox

    - by Antony
    Recently, I was trying to prototype some jQuery-based menu into ASP.NET MVC. Just to name two examples here: plugins.jquery.com/project/columnview www.filamentgroup.com/lab/jquery_ipod_style_and_flyout_menus/ Their demo page looks great, but when I integrate their sample code into MVC, the script no longer works in IE and FireFox, but it seems to work just fine under Google Chrome. Can someone kindly enough to point out what I missed? I will be honest here. I am still new to JavaScript, so it is still a learning phase to me, so any help is highly appreciated. I have placed a copy of my VS2010 solution zip file @ http://db.tt/0UNDkN Here is what I did. In the Site.Master, I have something like <body> <div class="page">{truncated...}</div> <script src="http://code.jquery.com/jquery-1.4.2.min.js" type="text/javascript" charset="utf-8"></script> <asp:ContentPlaceHolder ID="ScriptContent" runat="server" /> </body> And inside View file, I have the following <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <div id="original"> {some demo block, copied from javascript demo} </div> </asp:Content> <asp:Content ID="Content3" ContentPlaceHolderID="ScriptContent" runat="server"> <script type="text/javascript" src="<%= Url.Content("~/Scripts/jquery.columnview.js") %>" /> <script type="text/javascript"> $(document).ready(function () { $('#original').columnview(); }); </script> </asp:Content> Compiled the code and ran it under IE. Ideally, it should work like the demo in www.christianyates.com/blog/jquery/finder-column-view-hierarchical-lists-jquery, but in reality, it only displays unordered list in plain view. (If you download the solution file and run it, you should be able to repro this as well). Next, tried with FireFox, not working either, same result as IE. Finally, when I try it under Google Chrome 4.1 (lastest version), and the script displays just fine. Really puzzling here :-/ Thank you for reading :D

  • Special scheduling Algorithm (pattern expansion)

    - by tovare
    Question Do you think genetic algorithms worth trying out for the problem below, or will I hit local-minima issues? I think maybe aspects of the problem is great for a generator / fitness-function style setup. (If you've botched a similar project I would love hear from you, and not do something similar) Thank you for any tips on how to structure things and nail this right. The problem I'm searching a good scheduling algorithm to use for the following real-world problem. I have a sequence with 15 slots like this (The digits may vary from 0 to 20) : 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 (And there are in total 10 different sequences of this type) Each sequence needs to expand into an array, where each slot can take 1 position. 1 1 0 0 1 1 1 0 0 0 1 1 1 0 0 1 1 0 0 1 1 1 0 0 0 1 1 1 0 0 0 0 1 1 0 0 0 1 1 1 0 0 0 1 1 0 0 1 1 0 0 0 1 1 1 0 0 0 1 1 The constraints on the matrix is that: [row-wise, i.e. horizontally] The number of ones placed, must either be 11 or 111 [row-wise] The distance between two sequences of 1 needs to be a minimum of 00 The sum of each column should match the original array. The number of rows in the matrix should be optimized. The array then needs to allocate one of 4 different matrixes, which may have different number of rows: A, B, C, D A, B, C and D are real-world departments. The load needs to be placed reasonably fair during the course of a 10-day period, not to interfere with other department goals. Each of the matrix is compared with expansion of 10 different original sequences so you have: A1, A2, A3, A4, A5, A6, A7, A8, A9, A10 B1, B2, B3, B4, B5, B6, B7, B8, B9, B10 C1, C2, C3, C4, C5, C6, C7, C8, C9, C10 D1, D2, D3, D4, D5, D6, D7, D8, D9, D10 Certain spots on these may be reserved (Not sure if I should make it just reserved/not reserved or function-based). The reserved spots might be meetings and other events The sum of each row (for instance all the A's) should be approximately the same within 2%. i.e. sum(A1 through A10) should be approximately the same as (B1 through B10) etc. The number of rows can vary, so you have for instance: A1: 5 rows A2: 5 rows A3: 1 row, where that single row could for instance be: 0 0 1 1 1 0 0 0 0 0 0 0 0 0 0 etc.. Sub problem* I'de be very happy to solve only part of the problem. For instance being able to input: 1 1 2 3 4 2 2 3 4 2 2 3 3 2 3 And get an appropriate array of sequences with 1's and 0's minimized on the number of rows following th constraints above.

  • Perl: Edit hyperlinks in nested tags that aren't on separate lines

    - by user305801
    I have an interesting problem. I wrote the following perl script to recursively loop through a directory and in all html files for img/script/a tags do the following: Convert the entire url to lowercase Replace spaces and %20 with underscores The script works great except when an image tag in wrapped with an anchor tag. Is there a way to modify the current script to also be able to manipulate the links for nested tags that are not on separate lines? Basically if I have <a href="..."><img src="..."></a> the script will only change the link in the anchor tag but skip the img tag. #!/usr/bin/perl use File::Find; $input="/var/www/tecnew/"; sub process { if (-T and m/.+\.(htm|html)/i) { #print "htm/html: $_\n"; open(FILE,"+<$_") or die "couldn't open file $!\n"; $out = ''; while(<FILE>) { $cur_line = $_; if($cur_line =~ m/<a.*>/i) { print "cur_line (unaltered) $cur_line\n"; $cur_line =~ /(^.* href=\")(.+?)(\".*$)/i; $beg = $1; $link = html_clean($2); $end = $3; $cur_line = $beg.$link.$end; print "cur_line (altered) $cur_line\n"; } if($cur_line =~ m/(<img.*>|<script.*>)/i) { print "cur_line (unaltered) $cur_line\n"; $cur_line =~ /(^.* src=\")(.+?)(\".*$)/i; $beg = $1; $link = html_clean($2); $end = $3; $cur_line = $beg.$link.$end; print "cur_line (altered) $cur_line\n"; } $out .= $cur_line; } seek(FILE, 0, 0) or die "can't seek to start of file: $!"; print FILE $out or die "can't print to file: $1"; truncate(FILE, tell(FILE)) or die "can't truncate file: $!"; close(FILE) or die "can't close file: $!"; } } find(\&process, $input); sub html_clean { my($input_string) = @_; $input_string = lc($input_string); $input_string =~ s/%20|\s/_/g; return $input_string; }

  • Using FindAll on a List<List<T>> type

    - by Ken Foster
    Assuming public class MyClass { public int ID {get; set; } public string Name {get; set; } } and List<MyClass> classList = //populate with MyClass instances of various IDs I can do List<MyClass> result = classList.FindAll(class => class.ID == 123); and that will give me a list of just classes with ID = 123. Works great, looks elegant. Now, if I had List<List<MyClass>> listOfClassLists = //populate with Lists of MyClass instances How do I get a filtered list where the lists themselves are filtered. I tried List<List<MyClass>> result = listOfClassLists.FindAll (list => list.FindAll(class => class.ID == 123).Count > 0); it looks elegant, but doesn't work. It only includes Lists of classes where at least one class has an ID of 123, but it includes ALL MyClass instances in that list, not just the ones that match. I ended up having to do List<List<MyClass>> result = Results(listOfClassLists, 123); private List<List<MyClass>> Results(List<List<MyClass>> myListOfLists, int id) { List<List<MyClass>> results = new List<List<MyClass>>(); foreach (List<MyClass> myClassList in myListOfLists) { List<MyClass> subList = myClassList.FindAll(myClass => myClass.ID == id); if (subList.Count > 0) results.Add(subList); } return results; } which gets the job done, but isn't that elegant. Just looking for better ways to do a FindAll on a List of Lists. Ken

  • JavaCC: How can one exclude a string from a token? (A.k.a. understanding token ambiguity.)

    - by java.is.for.desktop
    Hello, everyone! I had already many problems with understanding, how ambiguous tokens can be handled elegantly (or somehow at all) in JavaCC. Let's take this example: I want to parse XML processing instruction. The format is: "<?" <target> <data> "?>": target is an XML name, data can be anything except ?>, because it's the closing tag. So, lets define this in JavaCC: (I use lexical states, in this case DEFAULT and PROC_INST) TOKEN : <#NAME : (very-long-definition-from-xml-1.1-goes-here) > TOKEN : <WSS : (" " | "\t")+ > // WSS = whitespaces <DEFAULT> TOKEN : {<PI_START : "<?" > : PROC_INST} <PROC_INST> TOKEN : {<PI_TARGET : <NAME> >} <PROC_INST> TOKEN : {<PI_DATA : ~[] >} // accept everything <PROC_INST> TOKEN : {<PI_END : "?>" > : DEFAULT} Now the part which recognizes processing instructions: void PROC_INSTR() : {} { ( <PI_START> (t=<PI_TARGET>){System.out.println("target: " + t.image);} <WSS> (t=<PI_DATA>){System.out.println("data: " + t.image);} <PI_END> ) {} } Let's test it with <?mytarget here-goes-some-data?>: The target is recognized: "target: mytarget". But now I get my favorite JavaCC parsing error: !! procinstparser.ParseException: Encountered "" at line 1, column 15. !! Was expecting one of: !! Encountered nothing? Was expecting nothing? Or what? Thank you, JavaCC! I know, that I could use the MORE keyword of JavaCC, but this would give me the whole processing instruction as one token, so I'd had to parse/tokenize it further by myself. Why should I do that? Am I writing a parser that does not parse? The problem is (i guess): hence <PI_DATA> recognizes "everything", my definition is wrong. I should tell JavaCC to recognize "everything except ?>" as processing instruction data. But how can it be done? NOTE: I can only exclude single characters using ~["a"|"b"|"c"], I can't exclude strings such as ~["abc"] or ~["?>"]. Another great anti-feature of JavaCC. Thank you.

  • Looking for Fiddler2 help. connection to gateway refused? Just got rid of a virus

    - by John Mackey
    I use Fiddler2 for facebook game items, and it's been a great success. I accessed a website to download some dat files I needed. I think it was eshare, ziddu or megaupload, one of those. Anyway, even before the rar file had downloaded, I got this weird green shield in the bottom right hand corner of my computer. It said a Trojan was trying to access my computer, or something to that extent. It prompted me to click the shield to begin anti-virus scanning. It turns out this rogue program is called Antivirus System Pro and is pretty hard to get rid of. After discovering the rogue program, I tried using Fiddler and got the following error: [Fiddler] Connection to Gateway failed.Exception Text: No connection could be made because the target machine actively refused it 127.0.0.1:5555 I ended up purchasing SpyDoctor + Antivirus, which I'm told is designed specifically for getting rid of these types of programs. Anyway, I did a quick-scan last night with spydoctor and malware bytes. Malware picked up 2 files, and Spydoctor found 4. Most were insignificant, but it did find a worm called Worm.Alcra.F, which was labeled high-priority. I don’t know if that’s the Anti-Virus Pro or not, but SpyDoctor said it got rid of all of those successfully. I tried to run Fiddler again before leaving home, but was still getting the "gateway failed" error. Im using the newest version of firefox. When I initially set up the Fiddler 2.2.8.6, I couldn’t get it to run at first, so I found this faq on the internet that said I needed to go through ToolsOptionsSettings and set up an HTTP Proxy to 127.0.0.1 and my Port to 8888. Once I set that up and downloaded this fiddler helper as a firefox add-on, it worked fine. When I turn on fiddler, it automatically takes my proxy setting from no proxy (default) to the 127.0.0.1 with Port 8888 set up. It worked fine until my computer detected this virus. Anyway, hopefully I've given you sufficient information to offer me your best advice here. Like I said, Spydoctor says the bad stuff is gone, so maybe the rogue program made some type of change in my fiddler that I could just reset or uncheck or something like that? Or will I need to completely remove fiddler and those dat files and rar files I downloaded? Any help would be greatly appreciated. Thanks for your time.

  • How do I add "Press any key to boot from usb" when installing Windows from a flash drive? (Grub4dos question / how to remove a bootloader)

    - by Vincent
    Hi there! I've been struggling with this problem for a while now and finially decided to ask for help. Let me first explain what the main purpose of the app is: to provide the a very easy to use way of backing up files, after which I format the drive and start Windows 7 setup. I do this by booting WinPE, which runs a script to detect Windows installations and then opens a file browser. After the file browser is closed, the script continues and formats the drive that contains the Windows installation, and starts an unattended Windows 7 install. Now here is the problem: When you start Windows setup or WinPE from a dvd, you get a nice option to "Press any key to boot from DVD". This is to prevent the computer from booting the DVD when the first phase of the installation is complete and the computer reboots. However, when booting from a flash drive, Windows does not provide this option: it simply boots the flash drive every reboot. To replicate the "press any key" function, I installed Grub4Dos, which works great. It provides a small menu, the first standard item being "Continue installation", the second being "start installation". After quite a lot of tweaking, I got everything working: Start installation starts WinPE, which in turn starts the Windows installation. At first reboot, the Grub4Dos menu comes up, counts 5 seconds and boots the second stage of the installation. Here, I am greeted with the error: "Windows setup could not configure windows to run on this computer's hardware." When I boot into WinPE the normal way (put the bootmgr on the stick root) and change my bios to boot from the primary hdd after first reboot, I don't get this error. I've been looking around, and the only thing I could find was that the BIOS automatically names the boot device hd0, and that Windows can only be run / installed to hd 0. I'm not sure if this is the problem. I read about remapping to solve this problem, but to do that you have to know the phisical location of the hard drive and partition, like hd(0,1). I want this flash drive to work on any PC, regardless of where the OS is installed, so that's not really a possibility. A possible fix I thought of is removing the bootloader from the flash drive when I'm in WinPE. That way, when the pc reboots the BIOS will not see the flash drive as a boot drive and instead boot the primary hdd. I have yet to find a way to do this. Thank you for reading my question, and if you have any suggestion, please do.

  • WPF performance for large number of elements on the screen

    - by Mark
    Im currently trying to create a Scene in WPF where I have around 250 controls on my screen and the user can Pan and Zoom in and out of these controls using the mouse. I have run the WPF Performance Suite tools on the application when there are a large number of these controls on the screen (i.e. when the user has zoomed right out) the FPS drops down to around 15 which is not very good. Here is the basic outline of the XAML: <Window> <Window.Resources> <ControlTemplate x:Key="LandTemplate" TargetType="{x:Type local:LandControl}"> <Canvas> <Path Fill="White" Stretch="Fill" Stroke="Black" StrokeThickness="1" Width="55.5" Height="74.687" Data="M0.5,0.5 L55,0.5 L55,74.187 L0.5,74.187 z"/> <Canvas x:Name="DetailLevelCanvas" Width="24.5" Height="21" Canvas.Left="15.306" Canvas.Top="23.972"> <TextBlock Width="21" Height="14" Text="712" TextWrapping="Wrap" Foreground="Black"/> <TextBlock Width="17.5" Height="7" Canvas.Left="7" Canvas.Top="14" Text="614m2" TextWrapping="Wrap" FontSize="5.333" Foreground="Black"/> </Canvas> </Canvas> </ControlTemplate> </Window.Resources> ... <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> ... and so on... </Window> Ive tried to minimise the details in the control template and I even did a massive find and replace of the controls to just put their raw elements inline instead of using a template, but with no noticeable performance improvements. I have seen other SO questions about this and people say to do custom drawing, but I dont really see how that make sense when you have to zoom and pan like I do. If anyone can help out here, that would be great! Mark

  • js works inside the page but not in code behind

    - by Cristian Boariu
    Hi guys, I have this function put in a MasterPage, which shows up an mp3 player: <script type="text/javascript"> $(document).ready(function() { var stageW = 500; var stageH = 216; var cacheBuster = Date.parse(new Date()); var flashvars = {}; var params = {}; params.bgcolor = '#F6F6F6'; params.allowfullscreen = 'true'; flashvars.stageW = stageW; flashvars.stageH = stageH; flashvars.pathToFiles = ''; flashvars.settingsPath = '../mp3player/mp3player_settings.xml'; flashvars.xmlPath = '<%# getRestXmlPlayerUrl() %>'; flashvars.keepSelected = 't'; flashvars.selectedWindow = '4'; flashvars.slideshow = 't'; flashvars.imageWidth = '130'; flashvars.imageHeight = '130'; swfobject.embedSWF('swf/preview.swf?t=' + cacheBuster, 'myContent', stageW, stageH, '9.0.124', 'swf/expressInstall.swf', flashvars, params); }); </script> All works great. But, because i have some ajax on the page with update panel, the flash in not rendered when ajax requests occurs so i need to register this function and i've tried something like this: protected void Page_PreRender(object sender, EventArgs e) { Type cstype = this.GetType(); String csnameForPlayer = "applyStyleToMp3Player"; if (!Page.ClientScript.IsClientScriptBlockRegistered(cstype, csnameForPlayer)) { StringBuilder cstextForPlayer = new StringBuilder(); cstextForPlayer.Append(" $(document).ready(function() { " + " var stageW = 500;" + " var stageH = 216;" + " var cacheBuster = Date.parse(new Date());" + " var flashvars = {};" + " var params = {};" + " params.bgcolor = '#F6F6F6';" + " params.allowfullscreen = 'true';" + " flashvars.stageW = stageW;" + " flashvars.stageH = stageH;" + " flashvars.pathToFiles = '';" + " flashvars.settingsPath = '../mp3player/mp3player_settings.xml';" + " flashvars.xmlPath = '<%# getRestXmlPlayerUrl() %>';" + " flashvars.keepSelected = 't';" + " flashvars.selectedWindow = '4';" + " flashvars.slideshow = 't';" + " flashvars.imageWidth = '130';" + " flashvars.imageHeight = '130';" + " swfobject.embedSWF('swf/preview.swf?t=' + cacheBuster, 'myContent', stageW, stageH, '9.0.124', 'swf/expressInstall.swf', flashvars, params);" + "}); "); ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), csnameForPlayer, cstextForPlayer.ToString(), true); } } Well, this does not work. The flash player does not appear any more, so, i assume that is something wrong in the cstextForPlayer. I've spent over one hour to figure it out but i've failed. Does anyone see the problem? Thanks in advance.

  • CSS Rollovers: how to main "hit area" size when hidden image is larger than anchor area

    - by nukefusion
    I have a small problem and I don't think what I want to do can be achieved with just pure CSS, but I figured I'd ask anyway. Basically, I have one DIV which contains a hyperlinked element that is smaller in size to it's parent DIV. So in effect I have a square within a square with the inner square being the "hit area". When I mouse over this inner square I want the background of the outer square to change. I know it's not possible to change the parent DIV's background on a:hover, but I figured I could give the illusion of it happening by nesting a hidden image inside the anchor. This works great until I want to "roll off". The problem is that I want the image to disappear when I leave the area of the anchor tag, not the larger hidden image. Is this possible? For the benefit of everyone I've provided an example to demonstrate what I mean: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Test Rollover</title> <link href="main.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="d1"> <a href="#nogo"> <b id="b1"></b> <b id="b2"></b> </a> </div> </body> And the css: #b1 { width: 200px; height: 200px; top: 100px; left: 100px; background-color:aqua; position: absolute; } #b2 { width: 400px; height: 400px; background-color:lime; position: absolute; display: none; } #d1 { width: 400px; height: 400px; background-color:fuchsia; position: relative; } #d1 a:hover #b2 { display: block; } In this example I want the green outer square to disappear when I leave the bounds of the hidden inner blue square.
