• WPF Animate a Matrix using interpolation

  - by Mark

  I'm having a issue with my application that is using touch gestures to scale, translate and rotate my scene. I was using a TransformGroup which contained TranslateTransform, ScaleTransform and a RotateTransform but I could not get the movement correct, it always jumps and skips, so I moved to a MaxtrixTransform which I was able to use much easier to get my scene to be zoomable, rotatable and panable nicely. However, what I later found out was that you cannot animate smoothly (using interpolation) the values of a Matrix, for what reason I have no idea, but its part of the MSDN doco and the properties of the Matrix are not dependency properties anyways... Has anyone had any luck animating a matrix to make it smooth? The only idea(s) I have had is to animate a few different, custom DP which all have callbacks that I update the matrix from OR To convert the matrix to a set of Transform objects that I then animate and then afterwords convert back. Is there a smarter way to do this?

• Geolocation under firefox 3.6 requires Proxy Authentication?

  - by prem

  I am trying to share my location on geolocation enabled pages from firefox 3.6, but doesn't seem to get any kind of success or failures. When I wrote my custom js containing navigator.geolocation.getCurrentPosition(func1,func2), the success callback isn't called at all. When I tamper the http requests on firefox, the request to https://www.google.com/loc/json returns with status: 407 [Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )]... Yes, my network is behind a proxy server. But the same works with Chrome. I didn't try other browsers yet.

• How to make scrolling through images as fast as Apple's Photos app

  - by clozach

  The Goal — On an iPhone, to browse through several hundred locally-stored jpgs using a UIScrollView. The Problem — Like many others before me, I've tried implementing a scroll view based on Apple's Page Control sample code and found it lacking. The biggest issue I'm currently up against is that the sample code's architecture doesn't seem to scale. With just a few images loaded from disk, everything's fine. Once the number of images gets into the dozens, though, scrolling suffers terribly: the scrollview stutters mid-scroll with each new swipe. The only code I've toyed with that comes even close to being reasonably responsive is Three20, but even there the performance doesn't hold a candle to Photos. For now, I'm just using Three20, but a faster, custom solution would definitely be preferable.

• Set bold rows in a QTreeView

  - by taynaron

  I have a custom subclass of a QTreeView in a pyqt application. I'm trying to give the user the ability to highlight and "lowlight" (for lack of a better term) rows. Highlighted rows should have bold text and (optionally) a different background color. Any ideas? I'm considering StyleSheets as an option, but have so far been unable to get that to work. If I set the QTreeView's stylesheet: self.setStyleSheet("QTreeView::item:selected {border: 1px solid #567dbc;}") I can't figure out how to manually enable 'states' that would keep only the desired rows at a particular state. If I try setting an individual item's stylesheet: #modelIndex is a valid QModelIndex modelIndex.internalPointer().setStyleSheet() I get a segfault. I'm not convinced stylesheets are the way to go, I'm open to all ideas. Thanks!

• TableView - iVar reset when returning from details view

  - by iFloh

  Hi, anyone knows what I need to do to retain my TableView iVars whilst pushing a details view onto the navigation stack? I have an array and a date defined as iVars and the array is retained, whilst the date is not. I checked whether there may be an autorelease hidden somewhere but there are no obvious ones. The properties are defined as nonatomic, retain. I use custom NSDate category methods to determine specific dates at stages. These use NSDateComponents, NSRange and NSCalendar, for example: - (NSDate *)lastDayOfMonth: { NSCalendar *tmpCal = [NSCalendar currentCalendar]; NSDateComponents *tmpDateComponents = [tmpCal components:NSYearCalendarUnit | NSMonthCalendarUnit | NSEraCalendarUnit | NSWeekCalendarUnit | NSWeekdayOrdinalCalendarUnit fromDate:self]; NSRange tmpRange = [tmpCal rangeOfUnit:NSDayCalendarUnit inUnit:NSMonthCalendarUnit forDate:[tmpCal dateFromComponents:tmpDateComponents]]; [tmpDateComponents setDay:tmpRange.length]; [tmpDateComponents setHour:23]; [tmpDateComponents setMinute:59]; [tmpDateComponents setSecond:59]; return [[NSCalendar currentCalendar] dateFromComponents:tmpDateComponents]; } could they somehow be the reason?

• Why does Silverlight provides webcam and microphone support without any encoding API?

  - by Shurup

  In the list of new features in Silverlight 4 you will find following: Webcam and microphone to allow sharing of video and audio for instance for chat or customer service applications. Silverlight captures an audio stream as raw pcm. So how would you realize for example audio/video chat or client/server audio recording application without any encoding on the client side, where there is no APIs in Silverlight available? Much less in a Silverlight you cannot use an unmanaged dll. You can use a com automation (a new feature of the Silverlight 4, I think only for Windows) but only if it was already installed on the client side (do you know any encoding COM servers that are installed with the windows). Otherwise, how would you deploy a custom COM server within you Silverlight application? The only way I found is either to deploy a command-line encoding and use it with COM AutomationFactory.CreateObject("WScript.Shell") or to implement an encoding to use it in your own AudioSink.

• Root view controllers and modal dialogs

  - by Tony

  In a custom UIViewController, if I have a member UINavigationController that I initialize with self as the root view, like this: navController = [[UINavigationController alloc] initWithRootViewController:self]; then presenting a modal dialog does not hide the tab bar at the bottom of the screen. The result is that if the user switches to a different tab while a modal dialog is displayed, when they pop back to the tab that was displaying a modal dialog then subsequent calls to presentModalViewController do not display a modal dialog at all, even if I call dismissModalViewControllerAnimated as a result of the tab switch. If I initialize the UINavigationController with out setting self as the root controller, navigationController = [[UINavigationController alloc] init]; then the tab bar is hidden as expected. I've changed things in my program so that this isn't really an issue for me anymore, but I'm not sure that I understand why this is happening. Is it considered bad practice to have a navigation controller with self as the root, if the nav controller is going to be displaying modal dialogs?

• Extending configuration for .Net 3.5 Applications

  - by Maximiliano Rios

  Due to a requirement in my current project, I have to build a configuration manager to handle configurations that merge local config info with database one. Custom configuration doesn't fit my needs, problem is that I don't know what's the type before loading certain information, for example: Loading database information I will able to know what's myhandler's type. Not previously. So I thought to write my own handler but I can't let set blank as type for sections, in fact .net requires to know what's the type to match myhandler nodes. I'm thinking on building a different parser to read XML nodes but I would prefer to match this structure. I've not found any information to do that yet, is there any way? Can I extend or hook up something into the framework to be capable of loading on-the-fly types and validate nodes? Thanks in advance.

• Question on Win32 LogonUser API and the Logon Type

  - by Lalit_M

  We have developed a ASP.NET web application and has implemented a custom authentication solution using active directory as the credentials store. Our front end application uses a normal login form to capture the user name and password and leverages the Win32 LogonUser method to authenticate the user’s credentials. When we are calling the LogonUser method, we are using the LOGON32_LOGON_NETWORK as the logon type. The issue we have found is that user profile folders are being created under the C:\Users folder of the web server. The folder seems to be created when a new user who has never logged on before is logging in for the first time. As the number of new users logging into the application grows, disk space is shrinking due to the large number of new user folders getting created. Has anyone seen this behavior with the Win32 LogonUser method? Does anyone know how to disable this behavior?

• Block All Keyboard Input in a Linux Application (Using Qt or Mono)

  - by Evans

  Hi, I'm working on a online quiz client where we use a dedicated custom-made linux distro which contains only the quiz client software along with text editors and other utility software. When the user has started the quiz, I want to prevent him/her from minimizing the window/closing it/switching to the desktop or other windows. The quizzes can be attempted using only the mouse, so I need the keyboard to be completed disabled for the period of the quiz. How could I do this, using Qt or Mono? I'm ready to use any low-level libraries/drivers, if required. Thanks Evans

• SSIS Script Component Testing Strategy

  - by Paul Kohler

  This question is in respect to the script component specifically. I am aware of ssisUnit etc… With simple SSIS Scripts Components, it’s sufficient to let basic testing flesh out issues, however I am working with a script that has grown in complexity over time. To better test the functionality I am considering abstracting the script logic into a DLL that gets deployed with the package, and then use the custom component in the script. The advantage is that the function will be more testable etc but it’s one more deployment artefact that needs to be managed. My question is, does anyone know of a better way to test such an SSIS script in a more isolated manner than to run the whole package and examine the output?

• prevent _doPostBack getting rendered in button markup

  - by Christo Fur

  Hi Is it possible to prevent the _doPostBack() call getting rendered on a button? I would like add some custom logic prior to calling the postback. I have added an onClick event to the button e.g. <button id="manualSubmit" runat="server" class="manual-submit" onclick="$('#jeweller-form').hide();" /> However, this just gets rendered inline before the _doPostBack() But the postback gets fired before the jQueryHide takes place I would like to call my own JS function then manually trigger the postback any ideas?

• Manipulate Page Theme Programatically

  - by Aren B

  I've got the following Setup in my Theme: \App_Themes\Default\StyleSheet.css \App_Themes\Default\PrintStyleSheet.css The PrintStyleSheet.css file has a set of printing css rules set in them wrapped in an @Media Print { } block. I need a way to programmatically remove the PrintStyleSheet.css from the list of css files for ASP.NET to inject based on some flags. (Some instances we want to print the site verbatim without custom formatting). I know i could build a seperate theme without the PrintStyleSheet.css in it and switch the theme programmatically, however this would introduce duplication of my master stylesheet which is not acceptable. Any ideas?

• Testing ASP.NET security in Firefox

  - by blahblah

  I'm not sure whether this question belongs on StackOverflow or SuperUser, but here goes nothing... I'm trying to test out some basic security problems on my personal ASP.NET website to see exactly how the custom validators, etc. work when tampering with the data. I've been looking at the Firefox extension TamperData which seems to do the trick, but it doesn't feel very professional at all. The issues I'm having with TamperData is that the textbox for the POST data is way too small to hold the ASP.NET view-state, so I have to copy that data into Emacs and then back again to be productive at all. I also don't like that there doesn't seem to be an option to only tamper with data which is from/to localhost. Any ideas on better extensions for the task or better methods to test it?

• ASP.NET MVC based CMS - dynamic generation of form helpers

  - by user252160

  I am working on an ASP.NET MVC based CMS that presents a rather extreme case. The system must allow the user to add custom content types based on different fields, and for every field, one can add options and validations. The thing is that everything is stored in a complex DB and extracted at runtime using LINQ. I am pretty fresh with ASPNET MVC so the following dilemma came to mind How should I make the content creation view so that form helpers are not predefined int he view code but are loaded based on the type of the field ? Do I have to create a factory class that checks the value of the type property of the field, and then returns a helper based on that or there's a better way to do it. This one seems pretty rigid to me , because anytime I make a change in the Fieldtypes table, I will have to make sure to create a check for that new type too.

• GUI Framework for flash (as3)

  - by widgisoft

  I can't seem to find any GUI framework's for as3 that are as good as any the applications I already see out on the web; Is this something most people code themselves or am I missing something in flash itself? I'm looking for dialogs/windows, buttons, text boxes, combos, drop downs, menus, etc etc and the ability to extend the components to make new ones. I'd also prefer it to be as3 but any others will do also. May need to elaborate a little.. I'm actually looking for a framework to allow me to create my own GUIs in flash, custom skins, colors, styles, etc.

• jQuery AJAX converting variable string to html styled text

  - by sadmicrowave

  I've got an AJAX transmission of a variable string in my primary coding language (Visual FoxPro 9) that looks like this: AjaxResponse = CREATEOBJECT("Custom") lcMessage = "<li class='hello'>Hello</li>" AjaxResponse.AddProperty("Reply", lcMessage) Response.ContentType = "text/html" Response.Write(AjaxResponse.Reply) While using the jQuery function .ajax() I've created a success: function that looks like this: $.ajax({ url: 'index?Proc=GetUuserHistory', dataType: "html", success: function(data){ $("div#history-text").text(data); }; }); My problem is that the text inserting into 'div#history-text' is unformatted and contains the li tags still. I've tried substituting the .text for .prepend, .append, and .html with no luck...is there a way to convert this string back to html format after its been received using Ajax?

• Container of shared_ptr's but iterate with raw pointers

  - by Sean Lynch

  I have a class that holds a list containing boost::shared_ptrs to objects of another class. The class member functions that give access to the elemets in the list return raw pointers. For consistency I'd also like to be able to iterate with raw pointers instead of shared_ptrs. So when I dereference the list iterator, I'd like to get raw pointer, not a shared_ptr. I assume I need to write a custom iterator for this. Is this correct? If so can someone point me in the right direction - I've never done this before.

• debugging with internet explorer

  - by baiano

  I have some code that I thought I had written so that it would play nice on IE. But apparently it does not. I use IE8 for my testing and get quite frustrated with the built-in debugging 'tool'. I found that firebug has a javascript tool that debugs for IE but I have to click it for every page, wait for it to load and then test my script. Is there a way to make IE ALWAYS load the firebug .js file? I tried searching for way to set up a custom header file for my IE installation but was unsuccessful. Is there another tool out there that would be better/easier to use? Another way to test scripts for IE compatibility?

• Wicket : Can a Panel or Component react on a form submit without any boilerplate code?

  - by MRalwasser

  I am currently evaluating Wicket and I am trying to figure out how things work. I have a question regarding form submit and panels (or other components). Imagine a custom wicket panel which contains a text field, doing as-you-type validation using ajax. This panel is added to a form. How can the Panel react a form submit (let's say because javascript/ajax is unavailable)? I am currently only aware of one solution: calling a panel's method inside the Form onSubmit() method. But this seems not like a "reusable" approach here, because I have to add boilerplate code to every form's onSubmit() which contains the panel (and every developer which use the panel must know this). So here comes my question: Is there any way that a Panel/Component can "detect" a form submit in some way? Or is there any other solution beside this? Thank you.

• Where are events in Cocoa Touch?

  - by yesenin

  Hi all! I learn Cocoa Touch several days, and today have stuck while looking for way to implement a custom event. Event that I can see in Connection Inspector for my UIView subclass. What I have: There are a UILabel and MyView:UIView on MainVindow. MyView contains a UISlider. Interfaces for Controller and MyView // Controller.h @interface Controller : NSObject { IBOutlet UILabel *label; IBOutlet MyView *myView; } // I suppose that there should be something like -(IBAction) changeLabelValue for myView event @end // MyView.h @interface MyView : UIView { IBOutlet UISlider *slider; float value; } - (IBAction) changeValue; //for slider "Changed Value" event What I want: Add something in MyView that allows it to rise a event after change value. Can anybody help me? My main area in programming is .NET and I begin think that its terminology is not appropriate for this case. Thanks.
