  • Using Optical Flow in EmguCV

    - by Meko
    HI. I am trying to create simple touch game using EmguCV.Should I use optical flow to determine for interaction between images on screen and with my hand ,if changes of points somewhere on screen more than 100 where the image, it means my hand is over image? But how can I track this new points? I can draw on screen here the previous points and new points but It shows on my head more points then my hand and I can not track my hands movements. void Optical_Flow_Worker(object sender, EventArgs e) { { Input_Capture.SetCaptureProperty(Emgu.CV.CvEnum.CAP_PROP.CV_CAP_PROP_POS_FRAMES, ActualFrameNumber); ActualFrame = Input_Capture.QueryFrame(); ActualGrayFrame = ActualFrame.Convert<Gray, Byte>(); NextFrame = Input_Capture.QueryFrame(); NextGrayFrame = NextFrame.Convert<Gray, Byte>(); ActualFeature = ActualGrayFrame.GoodFeaturesToTrack(500, 0.01d, 0.01, 5); ActualGrayFrame.FindCornerSubPix(ActualFeature, new System.Drawing.Size(10, 10), new System.Drawing.Size(-1, -1), new MCvTermCriteria(20, 0.3d)); OpticalFlow.PyrLK(ActualGrayFrame, NextGrayFrame, ActualFeature[0], new System.Drawing.Size(10, 10), 3, new MCvTermCriteria(20, 0.03d), out NextFeature, out Status, out TrackError); OpticalFlowFrame = new Image<Bgr, Byte>(ActualFrame.Width, ActualFrame.Height); OpticalFlowFrame = NextFrame.Copy(); for (int i = 0; i < ActualFeature[0].Length; i++) DrawFlowVectors(i); ActualFrameNumber++; pictureBox1.Image = ActualFrame.Resize(320, 400).ToBitmap() ; pictureBox3.Image = OpticalFlowFrame.Resize(320, 400).ToBitmap(); } } private void DrawFlowVectors(int i) { System.Drawing.Point p = new Point(); System.Drawing.Point q = new Point(); p.X = (int)ActualFeature[0][i].X; p.Y = (int)ActualFeature[0][i].Y; q.X = (int)NextFeature[i].X; q.Y = (int)NextFeature[i].Y; p.X = (int)(q.X + 6 * Math.Cos(angle + Math.PI / 4)); p.Y = (int)(q.Y + 6 * Math.Sin(angle + Math.PI / 4)); p.X = (int)(q.X + 6 * Math.Cos(angle - Math.PI / 4)); p.Y = (int)(q.Y + 6 * Math.Sin(angle - Math.PI / 4)); OpticalFlowFrame.Draw(new Rectangle(q.X,q.Y,1,1), new Bgr(Color.Red), 1); OpticalFlowFrame.Draw(new Rectangle(p.X, p.Y, 1, 1), new Bgr(Color.Blue), 1); }

  • AutoMapper recursive

    - by fra
    Hi! I would like to make a deep copy of a complex object tree using AutoMapper. The problem is that for each member I would like to construct a new object and then map it, and not simply copying the existing one. Here it is an example: public abstract class Test { public Test() { this.Id = Guid.NewGuid(); } public Guid Id { get; private set; } } public class OuterTest : Test { public InnerTest Inner { get; set; } } public class InnerTest : Test { public int Value { get; set; } } and how to test it: OuterTest outerDest = Mapper.Map<OuterTest, OuterTest>(outerSource); System.Diagnostics.Debug.WriteLine("InnerSource id: " + innerSource.Id); System.Diagnostics.Debug.WriteLine("InnerSource value: " + innerSource.Value); System.Diagnostics.Debug.WriteLine("OuterSource id: " + outerSource.Id); System.Diagnostics.Debug.WriteLine("OuterDest id: " + outerDest.Id); System.Diagnostics.Debug.WriteLine("OuterDest.Inner id: " + outerDest.Inner.Id); System.Diagnostics.Debug.WriteLine("OuterDest.Inner value: " + outerDest.Inner.Value); This is the result from the output window: InnerSource id: a60fda37-206a-40a8-a7f8-db480149c906 InnerSource value: 2119686684 OuterSource id: 7486899e-2da8-4873-9160-d6096b555c73 OuterDest id: 7486899e-2da8-4873-9160-d6096b555c73 OuterDest.Inner id: a60fda37-206a-40a8-a7f8-db480149c906 OuterDest.Inner value: 2119686684 The problem is thet the object innerSource is always the same instance as outerDest.Inner (I verified through MakeObjectId of VS debugger) but I would like them to be two different instances. How could I create a recursive map with this behavior? I tried creating a custom IValueResolver like the following, without success. public class AutoMapperNewObjectResolver : IValueResolver { public ResolutionResult Resolve(ResolutionResult source) { object resolved; if (source.Value != null) { object instance = Activator.CreateInstance(source.MemberType); resolved = Mapper.Map(source.Value, instance, source.MemberType, source.MemberType); } else { resolved = null; } ResolutionResult result = source.New(resolved, source.Context.DestinationType); return result; } } and configured like this: Mapper.CreateMap<OuterTest, OuterTest>() .ForMember(d => d.Inner, o => o.ResolveUsing<AutoMapperNewObjectResolver>().FromMember(src => src.Inner)); Any help appreciated, thank you

  • IE7 not digesting JSON: "parse error" [resolved]

    - by Kenny Leu
    While trying to GET a JSON, my callback function is NOT firing. $.ajax({ type:"GET", dataType:'json', url: myLocalURL, data: myData, success: function(returned_data){alert('success');} }); The strangest part of this is that my JSON(s) validates on JSONlint this ONLY fails on IE7...it works in Safari, Chrome, and all versions of Firefox, (EDIT: and even in IE8). If I use 'error', then it reports "parseError"...even though it validates! Is there anything that I'm missing? Does IE7 not process certain characters, data structures (my data doesn't have anything non-alphanumeric, but it DOES have nested JSONs)? I have used tons of other AJAX calls that all work (even in IE7), but with the exception of THIS call. An example data return (EDIT: This is a structurally-complete example, meaning it is only missing a few second-tier fields, but follows this exact hierarchy)here is: {"question":{ "question_id":"19", "question_text":"testing", "other_crap":"none" }, "timestamp":{ "response":"answer", "response_text":"the text here" } } I am completely at a loss. Hopefully someone has some insight into what's going on...thank you! EDIT Here's a copy of the SIMPLEST case of dummy data that I'm using...it still doesn't work in IE7. { "question":{ "question_id":"20", "question_text":"testing :", "adverse_party":"none", "juris":"California", "recipients":"Carl Chan" } } EDIT 2 I am starting to doubt that it is a JSON issue...but I have NO idea what else it could be. Here are some other resources that I've found that could be the cause, but they don't seem to work either: http://firelitdesign.blogspot.com/2009/07/jquerys-getjson.html (Django uses Unicode by default, so I don't think this is causing it) Anybody have any other ideas? ANSWER I finally managed to figure it out...mostly via tedious trial-and-error. I want to thank everyone for their suggestions...as soon as I have 15 rep, I'll upvote you, I promise. :) There was basically no way that you guys could have figured it out, because the issue turned out to be a strange bug between IE7 and Django (my research didn't bring up any similar issues). We were basically using Django template language to generate our JSON...and in the midst of this particular JSON, we were using custom template tags: {% load customfilter %} { "question":{ "question_id":"{{question.id}}", "question_text":"{{question.question_text|customfilterhere}}" } } As soon as I deleted anything related to the customfilter, IE7 was able to parse the JSON perfectly! We still don't have a workaround yet, but at least we now know what's causing it. Has anyone seen any similar issues? Once again, thank you everyone for your contributions.

  • WPF Debugging AvalonEdit binding to Document property.

    - by kubal5003
    Hello, all day long I am sitting and trying to find out why binding to AvalonEdits Document property isn't working. AvalonEdit is an advanced WPF text editor - part of the SharpDevelop project.(it's going to be used in SharpDevelop v4 Mirador). So when I set up a simple project - one TextEditor (that's the AvalonEdits real name in the library) and made a simple class that has one property - Document and it returns a dummy object with some static text the binding is working perfectly. However in real life solution I'm binding a collection of SomeEditor objects to TabControl. TabControl has DataTemplate for SomeEditor and there's the TextEditor object. <TabControl Grid.Column="1" x:Name="tabControlFiles" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" > <TabControl.Resources> <DataTemplate DataType="{x:Type m:SomeEditor}"> <a:TextEditor Document="{Binding Path=Document, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource NoopConverter}, IsAsync=True}" x:Name="avalonEdit"></a:TextEditor> </DataTemplate> </TabControl.Resources> <TabControl.ItemContainerStyle> <Style BasedOn="{StaticResource TabItemStyle}" TargetType="{x:Type TabItem}"> <Setter Property="IsSelected" Value="{Binding IsSelected}"></Setter> </Style> </TabControl.ItemContainerStyle> </TabControl> This doesn't work. What I've investigated so far: DataContext of TextEditor is set to the proper instance of SomeEditor TextEditors Document property is set to some other instance than SomeEditor.Document property when I set breakpoint to no-op converter that is attached to that binding it shows me the correct value for Document (the converter is used!) I also dug through the VisualTree to obtain reference to TextEditor and called GetBindingExpression(TextEditor.DocumentProperty) and this did return nothing WPF produces the following information: System.Windows.Data Information: 10 : Cannot retrieve value using the binding and no valid fallback value exists; using default instead. BindingExpression:Path=Document; DataItem='SomeEditor' (HashCode=26280264); target element is 'TextEditor' (Name='avalonEdit'); target property is 'Document' (type 'TextDocument') SomeEditor instance that is bound to already has a created and cached copy of Document before the binding occurs. The getter is never called. Anyone can tell me what might be wrong? Why BindingExpression isn't set ? Why property getter is never called?

  • Why does DEP kill IE when accessing Microsoft FTP?

    - by Sammy
    I start up IE (9.0.8112.16421) with about:blank and I go to ftp://ftp.microsoft.com/ I press Alt, click View and then Open FTP Site in Windows Explorer. At this point IE stops responding and eventually crashes (though the window is still active, sometimes) and I get the usual Windows dialog box saying that the program has stopped working. From this dialog box I click on the option to try to find solutions to the problem and the progress bar just keeps scrolling without giving me any result page whatsoever, so I have to abort by clicking Cancel. Then I get the bubble type of pop-up message from the system tray saying that DEP has stopped the program from executing. What gives? Why would DEP (part of Microsoft Windows) be preventing IE (a Microsoft product) from performing a perfectly legitimate action from Microsoft's own FTP site? The OS is Windows Vista HP SP2, Swedish locale. Screenshots as follows... Update: I normally have UAC disabled, but I have discovered that enabling it has an effect on IE when I click the FTP option from the View menu, just as I suspected. I basically tried starting IE in its 32-bit and 64-bit version, with and without add-ons, and switching UAC on and off, and then trying to go to View and the FTP option (as shown above). Here are the results. With UAC off and DEP on Action: IE 32-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: crash Action: IE 32-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: crash Action: IE 64-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: information & warning message Action: IE 64-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: information & warning message This is the information and warning message I get if I use IE 64-bit: The first message is an FTP proxy warning. It says that the folder ftp://ftp.microsoft.com/ will be write-protected because proxy server is not configured to allow full access. It goes on to say that if I want to move, paste, change name or delete files I must use another type of proxy, and that I should contact the system admin for more information (the usual recommendation when they have no clue of what's going on). What the heck is all this about? I don't even use a proxy server, as you can see from the next screenshot (Internet Options, Connections, LAN settings dialog). That second message only states that the FTP site cannot be viewed in (Windows) Explorer. With UAC off, I always get these two messages when running the 64-bit version of IE. With UAC on and DEP on Action: IE 32-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: crash Action: IE 32-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: security warning message, prompts to allow action Action: IE 64-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: security warning message, prompts to allow action Action: IE 64-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: security warning message, prompts to allow action As you can see from this list, if I have UAC enabled I actually get rid of these messages and opening the FTP site in Windows Explorer (from IE) actually works (except for 32-bit version which still crashes). Here is the security warning message: The fact that the 32-bit IE still crashes could be an indicator that this has something to do with one or several add-ons in that bit-version of IE. The 32-bit IE doesn't crash if it's started with the extoff flag. If this is affecting only the 32-bit IE then it's only normal that the 64-bit IE doesn't have this problem because it would not be using any of the add-ons used by the 32-bit version, they are not compatible with 64-bit (although some add-ons work both with 32-bit and 64-bit IE). Figuring out which add-on (if any) is causing this problem is a whole new question... but I seem to be closer to an answer now, and a possible solution. I could of course just add IE (32-bit) in the exclusion list of DEP. In fact, I have already tested this and it causes IE to perform this task without hiccups. But I don't really want to disable DEP, or force it on all Windows programs and services (except the ones I strictly specify in the exception list). (In other words DEP can't really be completely disabled, you can only switch between two modes of operation.) Update 2: This is interesting... I start 32-bit IE, go to ftp://ftp.microsoft.com/ and click on View, and Open FTP Site in Windows Explorer. The result is a crash!! Then I start 32-bit IE with extoff flag to disable add-ons, I go to ftp://ftp.microsoft.com/ and click on View, and Open FTP Site in Windows Explorer. I get the security warning, as expected with UAC enabled, and it opens up in Windows Explorer. Now... I close Windows Explorer, and I close IE. I then start 32-bit IE (normal start, with add-ons), I go to ftp://ftp.microsoft.com/ and click on View, and Open FTP Site in Windows Explorer. Now this time it doesn't crash! Instead, I get the screenshot number 5 as seen above. This is the FTP proxy warning message. Now get this... if I click the close button to get rid of this message, what happens is that Firefox starts up, and it goes to ftp://ftp.microsoft.com/ The fact that this works with 32-bit IE (with add-ons) the second time around, is because I am still logged in as anonymous to the FTP server. The log-in has not timed out yet. Standard log-in timeout for FTP servers is usually 60 to 120 seconds. I got logged in to it the first time I ran 32-bit IE with the extoff flag (no add-ons) which actually works and connects using Windows Explorer. Update 3: The connection to the FTP server has timed out by now. So now if I run 32-bit IE (with add-ons) and repeat the steps as before it crashes, just as expected... In conclusion: If I have already been connected to the FTP server via Windows Explorer, and I go to this FTP address in 32-bit IE and I pick the FTP option from the view menu to open it in Windows Explorer, it gives me a FTP proxy server warning and then opens the address in default web browser (Firefox in my case). If I have not been connected to the FTP server via Windows Explorer previously, and I go to this FTP address in 32-bit IE and I pick the FTP option from the view menu top open it in Windows Explorer, then it crashes IE! This is just great... It's not that I care much for using Internet Explorer or the Windows Explorer to log in to FTP servers. This just shows why IE is not the best browser choice. This reminds me of the time when Microsoft was enforcing the use of Internet Explorer as default browser for opening web links and other web resources, despite the fact that the user had installed an alternative browser on the system. Even if the user explicitly set the default browser to be something else and not Internet Explorer in the Windows options, IE would still pop up sometimes, depending on what web resources the user was trying to access. Setting default browser had no effect. It was hard-coded that IE is the browser of choice, especially when accessing Microsoft product or help pages. The web page would actually say that you are not using IE, and that you must open it in IE to view it. Unfortunately you would not be able to open it manually in a different browser by simply copying and pasting the URL from the address bar, because it would show a different URL, and the original URL would re-direct to the "you are using the wrong browser" page so you would not have the time to cut it to clipboard. Thankfully those days are over. Now-days Microsoft is forced to distribute IE and WMP free versions of Windows for the EU market. The way it should be! These programs have to be optional, not mandatory.

  • MSBuild: Add additional files to compile without altering the project file

    - by Craig Norton
    After looking around I can't find a simple answer to this problem. I am trying to create an MSBuild file to allow me to easily use SpecFlow and NUnit within Visual Studio 2010 express. The file below is not complete this is just a proof of concept and it needs to be made more generic. <Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <BuildDependsOn> BuildSolution; SpecFlow; BuildProject; NUnit; </BuildDependsOn> </PropertyGroup> <PropertyGroup> <Solution>C:\Users\Craig\Documents\My Dropbox\Cells\Cells.sln</Solution> <CSProject>C:\Users\Craig\Documents\My Dropbox\Cells\Configuration\Configuration.csproj</CSProject> <DLL>C:\Users\Craig\Documents\My Dropbox\Cells\Configuration\bin\Debug\Configuration.dll</DLL> </PropertyGroup> <Target Name="Build" DependsOnTargets="$(BuildDependsOn)"> </Target> <Target Name="BuildSolution"> <MSBuild Projects="$(Solution)" Properties="Configuration=Debug" /> </Target> <Target Name="SpecFlow"> <Exec Command="SpecFlow generateall $(CSProject)" /> </Target> <Target Name="BuildProject"> <MSBuild Projects="$(CSProject)" Properties="Configuration=Debug" /> </Target> <Target Name="NUnit"> <Exec Command='NUnit /run "$(DLL)"' /> </Target> The SpecFlow Task looks in the .csproj file and creates a SpecFlowFeature1.feature.cs. I need to include this file when building the .csproj so that NUnit can use it. I know I could modify (either directly or on a copy) the .csproj file to include the generated file but I'd prefer to avoid this. My question is: Is there a way to use the MSBuild Task to build the project file and tell it to include an additional file to include in the build? Thank you.

  • UML assignment question

    - by waitinforatrain
    Hi guys, Sorry, I know this is a very lame question to ask and not of any use to anyone else. I have an assignment in UML due tomorrow and I don't even know the basics (all-nighter ahead!). I'm not looking for a walkthrough, I simply want your opinion on something. The assignment is as follows (you only need to skim over it!): ============= Gourmet Surprise (GS) is a small catering firm with five employees. During a typical weekend, GS caters fifteen events with twenty to fifty people each. The business has grown rapidly over the past year and the owner wants to install a new computer system for managing the ordering and buying process. GS has a set of ten standard menus. When potential customers call, the receptionist describes the menus to them. If the customer decides to book an event (dinner, lunch, picnic, finger food etc.), the receptionist records the customer information (e.g., name, address, phone number, etc.) and the information about the event (e.g., place, date, time, which one of the standard menus, total price) on a contract. The customer is then faxed a copy of the contract and must sign and return it along with a deposit (often a credit card or by check) before the event is officially booked. The remaining money is collected when the catering is delivered. Sometimes, the customer wants something special (e.g., birthday cake). In this case, the receptionist takes the information and gives it to the owner who determines the cost; the receptionist then calls the customer back with the price information. Sometimes the customer accepts the price, other times, the customer requests some changes that have to go back to the owner for a new cost estimate. Each week, the owner looks through the events scheduled for that weekend and orders the supplies (e.g., plates) and food (e.g., bread, chicken) needed to make them. The owner would like to use the system for marketing as well. It should be able to track how customers learned about GS, and identify repeat customers, so that GS can mail special offers to them. The owner also wants to track the events on which GS sent a contract, but the customer never signed the contract and actually booked a GS. Exercise: Create an activity diagram and a use case model (complete with a set of detail use case descriptions) for the above system. Produce an initial domain model (class diagram) based on these descriptions. Elaborate the use cases into sequence diagrams, and include any state diagrams necessary. Finally use the information from these dynamic models to expand the domain model into a full application model. ============= In your opinion, do you think this question is asking me to come up with a package for an online ordering system to replace the system described above, or to create UML diagrams that facilitate the existing telephone-based system?

  • Automatically extracting inline XSD from WSDL into XSD file(s)

    - by Steven Geens
    I am using a third party Web Service whose definition and implementation are beyond my control. This web service will change in the future. The Web Service should be used to generate an XML file which contains some of the same data (represented by the same XSD types) as the Web Service plus some extra information generated by the program. My approach: create my own XSD referring to the XSD definitions of the WSDL of the called web service (This XSD also includes XSD types for the extra information obviously.) use a Java XML databinding framework (like ADB or JiXB) to generate the databinding classes from my own XSD file from step 1 use a Java SOAP framework (like Axis2 or CXF) with the same databinding framework to generate the databinding classes from the WSDL (This would enable me to use the objects retrieved by the web service directly in the generation of the XML.) The XSD types I am going to use in my own XSD file, but are defined in the WSDL, are subject to change. Whenever they change, I would like to automatically process the XSD and WSDL databinding again. (If the change is significant enough, this might trigger some development effort.(But usually not.)) My problem: In step 1 I need an XSD referring to the same types as used by the Web Service. The WSDL is referring to another WSDL, which is referring to another WSDL etc. Eventually there is an WSDL with the needed inline XSD types. As far as I know there is no way to directly reference the inline XSD types of a WSDL from an XSD. The approach I would think most viable, is to include an extra step in the automatic processing (before the databinding) that extracts the inline XSD from the WSDL into other XSD file(s). These other XSD file(s) can then be referred to by my own XSD file. Things I'd like to avoid: Manually copy pasting the inline XSD into an XSD file (I am looking for an automatic process.) Any manual steps.(Like the determining the WSDL that contains the inline types manually.(The location of that WSDL does change as well.)) Using xsd:any in my own XSD. I would like my own XSD file to be correct. Using a non-Java technology(like .NET) Huge amounts of implementation (but hints on how you would implement such an extraction are welcome anyway) PS: I found some similar questions, but they all had responses like: WTH would you want to do that? That is the reason for my rather large background story.

  • Django doesn't refresh my request object when reloading the current page.

    - by Boris Rusev
    I have a Django web site which I want ot be viewable in different languages. Until this morning everything was working fine. Here is the deal. I go to my say About Us page and it is in English. Below it there is the change language button and when I press it everything "magically" translates to Bulgarian just the way I want it. On the other hand I have a JS menu from which the user is able to browse through the products. I click on 'T-Shirt' then a sub-menu opens bellow the previously pressed containing different categories - Men, Women, Children. The link guides me to a page where the exact clothes I have requested are listed. BUT... When I try to change the language THEN, nothing happens. I go to the Abouts Page, change the language from there, return to the clothes catalog and the language is changed... I will no paste some code. This is my change button code: function changeLanguage() { if (getCookie('language') == 'EN') { setCookie("language", 'BG'); } else { setCookie("language", 'EN'); } window.location.reload(); } These are my URL patterns: urlpatterns = patterns('', # Example: # (r'^enter_clothing/', include('enter_clothing.foo.urls')), # Uncomment the admin/doc line below and add 'django.contrib.admindocs' # to INSTALLED_APPS to enable admin documentation: # (r'^admin/doc/', include('django.contrib.admindocs.urls')), # Uncomment the next line to enable the admin: (r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': '/home/boris/Projects/enter_clothing/templates/media', 'show_indexes': True}), (r'^$', 'enter_clothing.clothes_app.views.index'), (r'^home', 'enter_clothing.clothes_app.views.home'), (r'^products', 'enter_clothing.clothes_app.views.products'), (r'^orders', 'enter_clothing.clothes_app.views.orders'), (r'^aboutUs', 'enter_clothing.clothes_app.views.aboutUs'), (r'^contactUs', 'enter_clothing.clothes_app.views.contactUs'), (r'^admin/', include(admin.site.urls)), (r'^(\w+)/(\w+)/page=(\d+)', 'enter_clothing.clothes_app.views.displayClothes'), ) My About Us page: @base def aboutUs(request): return """<b>%s</b>""" % getTranslation("About Us Text", request.COOKIES['language']) The @base method: def base(myfunc): def inner_func(*args, **kwargs): try: args[0].COOKIES['language'] except: args[0].COOKIES['language'] = 'BG' resetGlobalVariables() initCollections(args[0]) categoriesByCollection = dict((collection, getCategoriesFromCollection(args[0], collection)) for collection in collections) if args[0].COOKIES['language'] == 'BG': for k, v in categoriesByCollection.iteritems(): categoriesByCollection[k] = reduce(lambda a,b: a+b, map(lambda x: """<li><a href="/%s/%s/page=1">%s</a></li>""" % (translateCategory(args[0], x), translateCollection(args[0], k), str(x)), v), "") else: for k, v in categoriesByCollection.iteritems(): categoriesByCollection[k] = reduce(lambda a,b: a+b, map(lambda x: """<li><a href="/%s/%s/page=1">%s</a></li>""" % (str(x), str(k), str(x)), v), "") contents = myfunc(*args, **kwargs) return render_to_response('index.html', {'title': title, 'categoriesByCollection': categoriesByCollection.iteritems(), 'keys': enumerate(keys), 'values': enumerate(values), 'contents': contents, 'btnHome':getTranslation("Home Button", args[0].COOKIES['language']), 'btnProducts':getTranslation("Products Button", args[0].COOKIES['language']), 'btnOrders':getTranslation("Orders Button", args[0].COOKIES['language']), 'btnAboutUs':getTranslation("About Us Button", args[0].COOKIES['language']), 'btnContacts':getTranslation("Contact Us Button", args[0].COOKIES['language']), 'btnChangeLanguage':getTranslation("Button Change Language", args[0].COOKIES['language'])}) return inner_func And the catalog page: @base def displayClothes(request, category, collection, page): clothesToDisplay = getClothesFromCollectionAndCategory(request, category, collection) contents = "" pageCount = len(clothesToDisplay) / ( rowCount * columnCount) + 1 matrixSize = rowCount * columnCount currentPage = str(page).replace("page=", "") currentPage = int(currentPage) - 1 #raise Exception(request) # this is for the clothes layout for x in range(currentPage * matrixSize, matrixSize * (currentPage + 1)): if x < len(clothesToDisplay): if request.COOKIES['language'] == 'EN': contents += """<div class="clothes">%s</div>""" % clothesToDisplay[x].getEnglishHTML() else: contents += """<div class="clothes">%s</div>""" % clothesToDisplay[x].getBulgarianHTML() if (x + 1) % columnCount == 0: contents += """<div class="clear"></div>""" contents += """<div class="clear"></div>""" # this is for the page links if pageCount > 1: for x in range(0, pageCount): if x == currentPage: contents += """<a href="/%s/%s/page=%s"><span style="font-size: 20pt; color: black;">%s</span></a>""" % (category, collection, x + 1, x + 1) else: contents += """<a href="/%s/%s/page=%s"><span style="font-size: 20pt; color: blue;">%s</span></a>""" % (category, collection, x + 1, x + 1) return """%s""" % (contents) Let me explain that you needn't be alarmed by the large quantities of code I have posted. You don't have to understand it or even look at all of it. I've published it just in case because I really can't understand the origins of the bug. Now this is how I have narrowed the problem. I am debuging with "raise Exception(request)" every time I want to know what's inside my request object. When I place this in my aboutUs method, the language cookie value changes every time I press the language button. But NOT when I am in the displayClothes method. There the language stays the same. Also I tried putting the exception line in the beginning of the @base method. It turns out the situation there is exactly the same. When I am in my About Us page and click on the button, the language in my request object changes, but when I press the button while in the catalog page it remains unchanged. That is all I could find, and I have no idea as to how Django distinguishes my pages and in what way. P.S. The JavaScript I think works perfectly, I have tested it in multiple ways. Thank you, I hope some of you will read this enormous post, and don't hesitate to ask for more code excerpts.

  • Issues with MIPS interrupt for tv remote simulator

    - by pred2040
    Hello I am writing a program for class to simulate a tv remote in a MIPS/SPIM enviroment. The functions of the program itself are unimportant as they worked fine before the interrupt so I left them all out. The gaol is basically to get a input from the keyboard by means of interupt, store it in $s7 and process it.

  • Session Id in url and/or cookie? [closed]

    - by Jacco
    Most people advice against rewriting every (internal) url to include the sessionId (both GET and POST). The standard argument against it seems to be:   If an attacker gets hold of the sessionId, they can hijack the session.   With the sessionId in the url, it easily leaks to the attacker (by referer etc.) But what if you put the sessionId in both an (encrypted) cookie and the url. if the sessionId in either the cookie or the url is missing or if they do not match, decline the request. Let's pretend the website in question is free of xss holes, the cookie encryption is strong enough, etc. etc. Then what is the increased risk of rewriting every url to include the sessionId? UPDATE: @Casper That is a very good point. so up to now there are 2 reasons: bad for search engines / SEO if used in public part of the website can cause trouble when users post an url with a session Id on a forum, send it trough email or bookmark the page apart from the:   It increases the security risk, but it is not clear what the increased risk is. some background info: I've a website that offers blog-like service to travellers. I cannot be sure cookies work nor can I require cookies to work. Most computers in internet cafes are old and not (even close to) up-to-date. The user has no control over them and the connection can be very unreliable for some more 'off the beaten path' locations. Binding the session to an IP-address is not possible, some places use load-balancing proxies with multiple IP addresses. (and from China there is The Great Firewall). Upon receiving the first cookie back, I flag cookies as mandatory. However, if the cookie was flagged as mandatory but not there, I ask for their password once more, knowing their session from the url. (Also cookies have a 1 time token in them, but that's not the point of this question). UPDATE 2: The conclusion seems to be that there are no extra *security* issues when you expose you session id trough the URL while also keeping a copy of the session id in an encrypted cookie. Do not hesitate to add additional information about any possible security implications

  • Div positioning problem related to Relative and Absolute positioning

    - by abszero
    Hello everyone. The problem I am running into is related to a footer I have absolutely positioned at the bottom of the page. Everything is fine until the copy on the page begins to extend further down the page which then causes my content wells to extend down, behind, the footer. Is there anyway I can force my content wells to 'push' the footer down the page? Here is the relevant html: <div id="page"> <div id="page_container"> <div id="header"></div> <div id="nav"></div> <div id="main_content"> <div id="left_column"></div> <div id="right_column"></div> </div> </div> </div> <div id="footer"> <div id="footer_container"> </div> </div> And the relevant CSS #page {width:100%;margin:0 0 10px 0; text-align:center;} #page_container {width:743px;height:auto !important;height:100%;margin:0 auto;min-height:100%;text-align:center;overflow:hidden;border:2px solid #000;} #header {width:100%;background:url('../images/header.jpg');height:87px;clear:both; margin-top: -2px;} #nav {width:100%;height:29px;float:left; text-align:left; border-bottom: solid 2px #000; border-top: solid 2px #000;} #main_content {width:100%;float:left; text-align:left; background-color:#fff; border-bottom: solid 2px #000; border-left: solid 2px #000; border-right: solid 2px #000;} #footer {width:100%; position:absolute;margin-top:10px; bottom: 0; background:url('../images/footer_bg.jpg');height:133px;text-align:center;} #footer_container{width:746px;height:133px; text-align:left; display:inline-block;} #left_column {width:230px; float:left; text-align:left; background-color:#fff; margin-top:5px;} #right_column {width:490px; float:right; text-align:left; background-color:#fff;margin-top:5px; padding:10px;} Thanks for any help you might be able to give!

  • Recursion in Java enums?

    - by davidrobles
    I've been trying for 3 hours and I just can't understand what is happening here. I have an enum 'Maze'. For some reason, when the method 'search' is called on this enum it's EXTREMELY slow (3 minutes to run). However, if I copy the same method to another class as a static method, and I call it from the enum 'Maze' it runs in one second! I don't understand why? is there any problem with recursive methods in Java enums?? What am I doing wrong? public enum Maze { A("A.txt"), B("B.txt"); // variables here... Maze(String fileName) { loadMap(fileName); nodeDistances = new int[nodes.size()][nodes.size()]; setNeighbors(); setDistances(); } ... more methods here ... private void setDistances() { nodeDistances = new int[nodes.size()][nodes.size()]; for (int i = 0; i < nodes.size(); i++) { setMax(nodeDistances[i]); // This works!!! TestMaze.search(nodes, nodeDistances[i], i, 0); // This DOESN'T WORK //search(nodes, nodeDistances[i], i, 0); } } public void setMax(int[] a) { for (int i=0; i<a.length; i++) { a[i] = Integer.MAX_VALUE; } } public void search(List<Node> allNodes, int[] distances, int curNodeIndex, int curDist) { if (curDist < distances[curNodeIndex]) { distances[curNodeIndex] = curDist; for (Node n : allNodes.get(curNodeIndex).getNeighbors()) { search(allNodes, distances, n.getNodeIndex(), curDist + 1); } } } } public class TestMaze { public static void search(List<Node> allNodes, int[] distances, int curNodeIndex, int curDist) { if (curDist < distances[curNodeIndex]) { distances[curNodeIndex] = curDist; for (Node n : allNodes.get(curNodeIndex).getNeighbors()) { search(allNodes, distances, n.getNodeIndex(), curDist + 1); } } } }

  • Search Display Controller Crashes When Returning Results

    - by Convolution
    I have a tableview with a search display controller. It has been working fine in the past, but recently has started crashing for certain search results. Here my code searches a Golfer based on their Name, Age and Handicap. The data is correctly loaded into the table, I can access and drill down to receive further information. However when I type in a search query for either Name or Age, the app crashes, while the Golfers Handicap is returned fine. Note: dataSouceArray is the data source for the tableview, dataSourceArrayCopy is the mutable copy of the data used to add and remove objects in the search filter. - (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope { /* Update the filtered array based on the search text and scope. */ [self.dataSourceArrayCopy removeAllObjects]; // First clear the filtered array. /* Search the main list for products whose type matches the scope (if selected) and whose name matches searchText; add items that match to the filtered array. */ for (Golfer *golfer in dataSourceArray) { if ([scope isEqualToString:@"Name"] || [golfer.golferName isEqualToString:scope]) { NSComparisonResult result = [golfer.golferName compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; if (result == NSOrderedSame) { [self.customerListCopy addObject:golfer]; } } if ([scope isEqualToString:@"Age"] || [golfer.golferAge isEqualToString:scope]) { NSComparisonResult result = [golfer.golferAge compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; if (result == NSOrderedSame) { [self.dataSourceArrayCopy addObject:golfer]; } } if ([scope isEqualToString:@"Handicap"] || [golfer.golferHandicap isEqualToString:scope]) { NSComparisonResult result = [golfer.golferHandicap compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; if (result == NSOrderedSame) { [self.dataSourceArrayCopy addObject:golfer]; } } } } - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { [self filterContentForSearchText:searchString scope: [[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]]; // Return YES to cause the search result table view to be reloaded. return YES; } - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchScope:(NSInteger)searchOption { [self filterContentForSearchText:[self.searchDisplayController.searchBar text] scope: [[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:searchOption]]; // Return YES to cause the search result table view to be reloaded. return YES; } Any help would be appreciated, thank you for taking the time to read this.

  • SQL Server 2008: FileStream Insertion Failure w/ .NET 3.5SP1

    - by James Alexander
    I've configured a db w/ a FileStream group and have a table w/ File type on it. When attempting to insert a streamed file and after I create the table row, my query to read the filepath out and the buffer returns a null file path. I can't seem to figure out why though. Here is the table creation script: /****** Object: Table [dbo].[JobInstanceFile] Script Date: 03/22/2010 18:05:36 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[JobInstanceFile]( [JobInstanceFileId] [int] IDENTITY(1,1) NOT NULL, [JobInstanceId] [int] NOT NULL, [File] [varbinary](max) FILESTREAM NULL, [FileId] [uniqueidentifier] ROWGUIDCOL NOT NULL, [Created] [datetime] NOT NULL, CONSTRAINT [PK_JobInstanceFile] PRIMARY KEY CLUSTERED ( [JobInstanceFileId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] FILESTREAM_ON [JobInstanceFilesGroup], UNIQUE NONCLUSTERED ( [FileId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] FILESTREAM_ON [JobInstanceFilesGroup] GO SET ANSI_PADDING OFF GO ALTER TABLE [dbo].[JobInstanceFile] ADD DEFAULT (newid()) FOR [FileId] GO Here's my proc I call to create the row before streaming the file: /****** Object: StoredProcedure [dbo].[JobInstanceFileCreate] Script Date: 03/22/2010 18:06:23 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO create proc [dbo].[JobInstanceFileCreate] @JobInstanceId int, @Created datetime as insert into JobInstanceFile (JobInstanceId, FileId, Created) values (@JobInstanceId, newid(), @Created) select scope_identity() GO And lastly, here's the code I'm using: public int CreateJobInstanceFile(int jobInstanceId, string filePath) { using (var connection = new SqlConnection(ConfigurationManager.ConnectionStrings["ConsumerMarketingStoreFiles"].ConnectionString)) using (var fileStream = new FileStream(filePath, FileMode.Open)) { connection.Open(); var tran = connection.BeginTransaction(IsolationLevel.ReadCommitted); try { //create the JobInstanceFile instance var command = new SqlCommand("JobInstanceFileCreate", connection) { Transaction = tran }; command.CommandType = CommandType.StoredProcedure; command.Parameters.AddWithValue("@JobInstanceId", jobInstanceId); command.Parameters.AddWithValue("@Created", DateTime.Now); int jobInstanceFileId = Convert.ToInt32(command.ExecuteScalar()); //read out the filestream transaction context to stream the file for storage command.CommandText = "select [File].PathName(), GET_FILESTREAM_TRANSACTION_CONTEXT() from JobInstanceFile where JobInstanceFileId = @JobInstanceFileId"; command.CommandType = CommandType.Text; command.Parameters.AddWithValue("@JobInstanceFileId", jobInstanceFileId); using (SqlDataReader dr = command.ExecuteReader()) { dr.Read(); //get the file path we're writing out to string writePath = dr.GetString(0); using (var writeStream = new SqlFileStream(writePath, (byte[])dr.GetValue(1), FileAccess.ReadWrite)) { //copy from one stream to another byte[] bytes = new byte[65536]; int numBytes; while ((numBytes = fileStream.Read(bytes, 0, 65536)) 0) writeStream.Write(bytes, 0, numBytes); } } tran.Commit(); return jobInstanceFileId; } catch (Exception e) { tran.Rollback(); throw e; } } } Can someone please let me know what I'm doing wrong.

  • Form submit to target iframe only works once

    - by Pointy
    I'm having a really irritating problem doing something that I'm sure I've done before. The setup is this: There's a form which is submitted via a "click" handler on a button, though the submit is ultimately a simple call to the form's native submit() function. The form's target is an iframe, which is initially filled with an empty page (that is, its source object is an URL for an empty page). That is, the "target" attribute of the form is the same identifier (and yes, it's a valid identifier) as the "name" and "id" attributes of the iframe (and yes, it's unique) Now the goal of this setup is as follows: the form contains file upload fields. Should something be wrong with one of the files uploaded, the server will report back an error. If the error response (that is, the html page with a new copy of the form, along with appropriate error messages) were to be allowed to reload the original window, then the file input fields would be cleared. That's not good. Thus the form submits to the iframe, so that the response from the server can be a small page that knows it's in that hidden iframe, and knows to move the error messages up to the form. One more thing: the form itself is also in an iframe, as part of a popup modal dialog (like a jQuery UI dialog, only slightly different; same idea though). The setup works fine - on the first submit. In other words, if I supply nice happy files to upload, the server ships back the successful response, and the dialog is closed correctly. If I send a bogus file, the server responds with an error page that correctly copies its stuff up to the form page. On the second submit, however (like, if I fix the bogus file input field), the browser insists on sending the server response to a new browser tab. As far as I can tell, the form's "target" remains correct, the iframe "name" and "id" attributes aren't changed, and I even make sure to update the hidden iframe "window.name" and "window.id" values. None of that is helping; I always get a new browser tab. I'm trying to set up a slightly simpler test case to see if I can rule out some of my framework code (the stuff that does the submit), though via a few console.log() calls I think that stuff is OK; it's certainly OK on all the other dialogs etc. in the site. When/if I create a simpler version I'll post it. In the meantime, if any of you insanely smart people recognize this situation and know of a trick to make it work, I'd be really thankful. I see the same behavior in both Firefox (3.6) and Chrome, so it's got to be my problem and not a browser quirk (well, at least that's what I think to be true).

    When trying to run an Eclipse Dynamic Web Project under a Tomcat setup using WTP, it fails with the attached stacktrace.

  • How to update a user created Bitmap in the Windows API

    - by gamernb
    In my code I quickly generate images on the fly, and I want to display them as quickly as possible. So the first time I create my image, I create a new BITMAP, but instead of deleting the old one and creating a new one for every subsequent image, I just want to copy my data back into the existing one. Here is my code to do both the initial creation and the updating. The creation works just fine, but the updating one doesn't work. BITMAPINFO bi; HBITMAP Frame::CreateBitmap(HWND hwnd, int tol1, int tol2, bool useWhite, bool useBackground) { ZeroMemory(&bi.bmiHeader, sizeof(BITMAPINFOHEADER)); bi.bmiHeader.biSize = sizeof(BITMAPINFOHEADER); bi.bmiHeader.biWidth = width; bi.bmiHeader.biHeight = height; bi.bmiHeader.biPlanes = 1; bi.bmiHeader.biBitCount = 24; bi.bmiHeader.biCompression = BI_RGB; ZeroMemory(bi.bmiColors, sizeof(RGBQUAD)); // Allocate memory for bitmap bits int size = height * width; Pixel* newPixels = new Pixel[size]; // Recompute the output //memcpy(newPixels, pixels, size*3); ComputeOutput(newPixels, tol1, tol2, useWhite, useBackground); HBITMAP bitmap = CreateDIBitmap(GetDC(hwnd), &bi.bmiHeader, CBM_INIT, newPixels, &bi, DIB_RGB_COLORS); delete newPixels; return bitmap; } and void Frame::UpdateBitmap(HWND hwnd, HBITMAP bitmap, int tol1, int tol2, bool useWhite, bool useBackground) { ZeroMemory(&bi.bmiHeader, sizeof(BITMAPINFOHEADER)); bi.bmiHeader.biSize = sizeof(BITMAPINFOHEADER); HDC hdc = GetDC(hwnd); if(!GetDIBits(hdc, bitmap, 0, bi.bmiHeader.biHeight, NULL, &bi, DIB_RGB_COLORS)) MessageBox(NULL, "Can't get base image info!", "Error!", MB_ICONEXCLAMATION | MB_OK); // Allocate memory for bitmap bits int size = height * width; Pixel* newPixels = new Pixel[size]; // Recompute the output //memcpy(newPixels, pixels, size*3); ComputeOutput(newPixels, tol1, tol2, useWhite, useBackground); // Push back to windows if(!SetDIBits(hdc, bitmap, 0, bi.bmiHeader.biHeight, newPixels, &bi, DIB_RGB_COLORS)) MessageBox(NULL, "Can't set pixel data!", "Error!", MB_ICONEXCLAMATION | MB_OK); delete newPixels; } where the Pixel struct is just this: struct Pixel { unsigned char b, g, r; }; Why does my update function not work. I always get the MessageBox for "Can't set pixel data!" I used code similar to this when I was loading in the original bitmap from file, then editing the data, but now when I manually create it, it doesn't work.

  • Why Won't the WebSocket.onmessage Event Fire?

    - by SumWon
    Hey guys, After toying around with this for hours, I simply cannot find a solution. I'm working on a WebSocket server using "node.js" for a canvas based online game I'm developing. My game can connect to the server just fine, it accepts the handshake and can even send messages to the server. However, when the server responds to the client, the client doesn't get the message. No errors, nothing, it just sits there peacefully. I've ripped apart my code, trying everything I could think of to fix this, but alas, nothing. Here's a stripped copy of my server code. As I said before, the handshake works fine, the server receives data fine, but sending data back to the client does not. var sys = require('sys'), net = require('net'); var server = net.createServer(function (stream) { stream.setEncoding('utf8'); var shaken = 0; stream.addListener('connect', function () { sys.puts("New connection from: "+stream.remoteAddress); }); stream.addListener('data', function (data) { if (!shaken) { sys.puts("Handshaking..."); //Send handshake: stream.write( "HTTP/1.1 101 Web Socket Protocol Handshake\r\n"+ "Upgrade: WebSocket\r\n"+ "Connection: Upgrade\r\n"+ "WebSocket-Origin: http://192.168.1.113\r\n"+ "WebSocket-Location: ws://192.168.1.71:7070/\r\n\r\n"); shaken=1; sys.puts("Handshaking complete."); } else { //Message received, respond with 'testMessage' var d = "testMessage"; var m = '\u0000' + d + '\uffff'; sys.puts("Sending '"+m+"' to client"); var result = stream.write(m, "utf8"); sys.puts(result); /* Result comes as true, meaning that it pushed the data out. Why isn't the client seeing it?!? */ } }); stream.addListener('end', function () { sys.puts("Connection closed!"); stream.end(); }); }); server.listen(7070); sys.puts("Server Started!");
