• Looking for a jQuery Developer [closed]

  - by Caroline Pires

  Hi, We are currently looking for a jquery developer, experienced specifically with flowplayer, to integrate a video player into our web application prototype. The player interface is being built in html and has to be wired to the flash player using the flowplayer jquery library. We also hope to be able to overlay some html elements on top of the video. A few extra jquery tools (scrollable and overlay) should be integrated with our page design as well. We are under a tight deadline and need to start work on this ASAP. For any further details please contact me on: [email protected] Thank you, Caroline

• Auto Increment feature of SQL Server

  - by Rahul Tripathi

  I have created a table named as ABC. It has three columns which are as follows:- The column number_pk (int) is the primary key of my table in which I have made the auto increment feature on for that column. Now I have deleted two rows from that table say Number_pk= 5 and Number_pk =6. The table which I get now is like this:- Now if I again enter two new rows in this table with the same value I get the two new Number_pk starting from 7 and 8 i.e, My question is that what is the logic behind this since I have deleted the two rows from the table. I know that a simple answer is because I have set the auto increment on for the primary key of my table. But I want to know is there any way that I can insert the two new entries starting from the last Number_pk without changing the design of my table? And how the SQL Server manage this record since I have deleted the rows from the database??

• Flex - Tab View Multiple DataGrids and same dataProvider

  - by user283403

  I have a flex application in which I have a TabNavigator with multiple tabs and a datagrid in each of those tabs. I have bound s single array of data to each grid. What I want to do is to bind each grid with a particular set of data in that array i.e. to distribute array contents among grids based on data type. For example items starting with letter A could be displayed in first grid, B in second, starting with C in third and so on. Hence you can say alphabetically distribute the data on different grids. The problem is that the data will be added randomly by the user. To make one data array for each grid is not an option (due to design restrictions). Any suggestions please? Thanks in advance

• How to align MDIChild on left?

  - by lyborko

  Hi, I am trying hard to align MDIChild form to the left of the parent MDIForm setting Align:=alLeft at design time. Aparently aligned MDIChild is higher than parents client area (I do not know why), thats why vertical scrollbar appears on parent form. The problem is, that I want this form create dynamicaly; putting vertical Splitter between these MDIchild forms, in order to size them by mouse. But when I create Splitter it aligns itself totaly on the left, as if MDIChild form was not aligned (alLeft) at all. I set MDIChild parameters to: Align:=alLeft; Windowstate:=wsNormal; Borderstyle:=bsSizable; Does anybody solved this problem before? thanx a lot P.S Delphi 7, Win XP

• The height and width properties on my Flex 4 app arn't working

  - by ben

  In the opening application tag of my Flex 4 app, I set the width and height properties as follows: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" creationComplete="init()" backgroundColor.mainState="0x303030" xmlns:components="components.*" width="798" height="240"> What I go into Design mode in Flash Builder 4, the app is the correct size. But when I embed the .swf file into a HTML page, the application's background color covers the whole screen, and when the Flash Player Settings message box pops up it is outside of the area I defined in the code above. What am I doing wrong? Thanks for reading.

• lock file so that it cannot be deleted

  - by JoeCool

  I'm working with two independent c/c++ applications on Windows where one of them constantly updates an image on disk (from a webcam) and the other reads that image for processing. This works fine and dandy 99.99% of the time, but every once in a while the reader app is in the middle of reading the image when the writer deletes it to refresh it with a new one. The obvious solution to me seems to be to have the reader put some sort of a lock on the file so that the writer can see that it can't delete it and thus spin-lock on it until it can delete and update. Is there anyway to do this? Or is there another simple design pattern I can use to get the same sort of constant image refreshing between two programs? Thanks, -Robert

• Is it faster to do the pages first and CSS second, or should I do them at the same time?

  - by Fred Haslam

  I have been tasked with building a new web project from scratch, with the exception of reusing CSS files (the look and feel) from an existing project. In the past I have always completed development of the functionality and the web-ui before considering the appearance. This is mostly due to CSS development overlapping with the tail end of the project. I now have the opportunity to integrate a static set of CSS as I build the application. I have no experience with this circumstance. Would it be faster to develop the project and web-pages first, then integrate the CSS; or would it be faster to integrate the CSS as part of page development?

• Auto-generate WebControls

  - by Adrian K

  I want to generate .net code from a template so that it more rapid, so lazy developers (and I mean that in the nicest possible way!) don't have to write them in the IDE, compile them, etc... I know I can roll my own tool which generates the code using reflection (by reading in some text file, etc), but I just wondered if there was an easier than starting from scratch since this is what ASP.NET basically does already; so is there anyway to leverage this? E.g. to quote Peter A. Bromberg: Even an ASPX page with no code on it gets turned into an instance of the System.Web.UI.Page class. The page is parsed by the ASP.NET engine when it is first requested, and then its JIT compiled version is cached in the Temporary ASP.NET Files folder as long as the application is running and the .aspx page hasn't been changed. Ideally I want to auto-generate WebControls, but examples of anything closely related will do. C# Examples preferred also, but anything considered :)

• deep injection - spring

  - by Bob

  What is the best way (or options) for accessing spring components at layers deep within the application that aren't managed by spring? For example, I have a low level utility POJO class into which I need to autowire/inject a spring component. I'll call it LowLevelHelper. There are multiple classes that use LowLevelHelper - most are layers away from anything that is hooked up with spring. One option would be to make all the layers in to spring components, but that seems like I'm hacking my design to force spring to help me. I have some complex things going on that won't be nearly as clean if I have to @Autowire all the pieces and don't new anything. Another option might be to manually inject the component in the low level class, but I'm not really sure if this is possible or the right solution.

• jQuery - events won't fire for dynamically created tab elements..

  - by Amit

  Hi, I am using jQuery UI Tabs. <div id="tabs"> <ul id="tablist"> <li><a href="#fragment-1"><span>One</span></a></li> </ul> </div> I have a button that adds new tabs. I use the following code: var newTabId = $('#tabs').tabs('option', 'selected') + 1; $('#tabs').tabs("add",'someUrl.htm','New Tab',newTabId); (Tab will be added next to the currently selected tab) Now none of the newly added tabs fire any events such as a click or hover $('#tablist li').click(function(){ alert('test message'); }); But events fire properly for the tabs that were there in the initial source code. How to resolve?

• How are binding specified for Interface Builder plugins?

  - by Benedict Cohen

  I'm creating an Interface Builder plugin for an NSView subclass. I've been following the Interface Builder Plug-in Programming Guide but it's not answer all my questions. My class has one NSString property and 4 NSColor properties which I want to create bindings for at design time. I can't figure out where the bindings are specified in the plugin project. The documentation states that the Inspector Object is only for creating the Attribute Inspector. The class description file (.classdescription) lists outlets and actions but not bindings. Where do I specify the bindings for my class?

• Set property on usercontrol that can be used in custom panel in control... Silverlight

  - by Dimestore Cowboy

  I have a simple usercontrol that uses a simple custom panel where I just overrode the Orientation and Measure functions. What I want to do is to have a property in the usercontol to control the orientation So I basicaly have UserControl -- Listbox -- MyPanel And I want a property for the usercontrol that can be set in xaml (of type System.Windows.Controls.Orientation ) that I can bind to from my custom panel (or a different approach if binding isnt the right way to do it) It would be a bonus if that property could show up in the properties window and you could select vertical or horizontal. And a super bonus if I could change the property at design time and have the listbox/

• Books or Articles on Using NUnit to Test Entire Features

  - by INTPnerd

  Are there any books or articles that show you how to use NUnit to test entire features of a program? Is there a name for this type of testing? This is different from the typical use of NUnit for unit testing where you test individual classes. This is similar to acceptance testing except that it is written by the developer to discern that the program does what they interpreted as being what the customer wants the program to do. I don't need it to be readable by non-programmers or to produce a readable specification for non-programmers. The problem I am having is keeping this feature testing code maintainable. I need help in organizing my feature testing code. I also need help organizing the program code to be drivable in this way. I am having a hard time being able to issue commands to the program while still having good code design.

• Adobe After Effects Plugin With Cocoa (Overriding malloc)

  - by mustISignUp

  Messing about a bit, i have a working Adobe After Effects plugin with a bit of Obj-c / Cocoa in it (NSArray and custom objects - not ui stuff). The SDK guide states:- Always use After Effects memory allocation functions. In low-memory conditions (such as during RAM preview), it’s very important that plug-ins not compete with After Effects for OS memory, and deal gracefully with out-of-memory conditions. Failing to use our functions can cause lock-ups, crashes, and tech support calls. Don’t do that. If you’re wrapping existing C++ code, overloading new and delete to use our functions will save substantial reimplementation. On Windows, derive all classes from a common base class which implements new and delete. so my question.. is something compatible with the above statement possible in Obj-c?

• Hook for redraw event in Blackberry

  - by Bendlas

  Is there a way to add a redraw callback to a live screen object, i.e. not via inheritance? Reasoning: I want to draw an overlay from an extension for widget sdk (substituting defunct position:absolute), so the screen is created by the bbwp stub. I can get it by Ui.getUiEngine().getActiveScreen() and draw on it quite nicely, but I need a way to redraw when appropriate. Note: I've abandoned the approach to push the overlay as a screen, because i couldn't make it transparent / find a way to pass events through.

• Unhandled exceptions in BackgroundWorker

  - by edg

  My WinForms app uses a number of BackgroundWorker objects to retrieve information from a database. I'm using BackgroundWorker because it allows the UI to remain unblocked during long-running database queries and it simplifies the threading model for me. I'm getting occasional DatabaseExceptions in some of these background threads, and I have witnessed at least one of these exceptions in a worker thread while debugging. I'm fairly confident these exceptions are timeouts which I suppose its reasonable to expect from time to time. My question is about what happens when an unhandled exception occurs in one of these background worker threads. I don't think I can catch an exception in another thread, but can I expect my WorkerCompleted method to be executed? Is there any property or method of the BackgroundWorker I can interrogate for exceptions?

• Using file-path to images stored within the Application Settings

  - by Bill

  I am trying to develop an application that uses a number of images that are stored in a seperate remote file location. The file-paths to the UI elements are stored within the Application Settings. Although I understand how to access and use the file-path from Settings in C# (Properties.Settings.Default.pathToGridImages + "OK.png"), I am at a loss to figure out how to utilize the Settings paths in WPF, and can only seem to access the file if I include the file-path, such as: <Grid.Background> <ImageBrush ImageSource="C:\Skins\bottomfill.png" TileMode="Tile" /> </Grid.Background> I would have thought that concatenating "Properties.Settings.Default.pathToGridImages" with "bottomfill.png" in WPF could be done much like it can be done in C#. Can anyone please point me in the right direction?

• Can I add custom methods/attributes to built-in Python types?

  - by sfjedi

  For example—say I want to add a helloWorld() method to Python's dict type. Can I do this? JavaScript has a prototype object that behaves this way. Maybe it's bad design and I should subclass the dict object, but then it only works on the subclasses and I want it to work on any and all future dictionaries. Here's how it would go down in JavaScript: String.prototype.hello = function() { alert("Hello, " + this + "!"); } "Jed".hello() //alerts "Hello, Jed!" Here's a useful link with more examples— http://www.javascriptkit.com/javatutors/proto3.shtml

• TextBox.TextChanged & ICommandSource

  - by Brad Leach

  I am following the M-V-VM pattern for my WPF UI. I would like to hook up a command to the TextChanged event of a TextBox to a command that is in my ViewModel class. The only way I can conceive of completing this task is to inherit from the TextBox control, and implement ICommandSource. I can then instruct the command to be fired from the TextChanged event. This seems to be too much work for something which appears to be so simple. Is there an easier way (than subclassing the TextBox and implementing ICommandSource) to hook up the TextChanged event to my ViewModel class?

• Using jQuery to create a video switcher

  - by techcastoni

  I've got a design for a video page which has a main video panel which will load the FLV file into JWPlayer when a thumbnail image is clicked. I think what I'm looking for is a partial page refresh? What is the best way to achieve this effect? This is the script I am using to display the video panel: var s1 = new SWFObject('player.swf','player','682','407','9'); s1.addParam('allowfullscreen','true'); s1.addParam('allowscriptaccess','always'); s1.addParam('flashvars','file=Welcome.f4v'); s1.write('preview');

• How to change the layout of the CreateUserWizard control?

  - by Bazzz

  How to change just the layout (template) of the CreateUserWizard control programmatically? I would to define another layout (not using the horrid table) but continue to use all the event handling and the creation of the user of the CreateUserWizard control. Just for reference, the following code doesn't work, and produces an unexpected result not representing my Template at all. The "InstantiateIn" method of the ITemplate is not called. public partial class b : System.Web.UI.Page { protected void Page_Init(object sender, EventArgs e) { CreateUserWizard createUserWizard = new CreateUserWizard(); createUserWizard.CreateUserStep.ContentTemplate = new Template(); Panel1.Controls.Add(createUserWizard); } } public class Template : ITemplate { void ITemplate.InstantiateIn(Control container) { container.Controls.Add(new TextBox() { ID = "UserName" }); container.Controls.Add(new TextBox() { ID = "Password" }); container.Controls.Add(new TextBox() { ID = "ConfirmPassword" }); container.Controls.Add(new TextBox() { ID = "Email" }); container.Controls.Add(new PlaceHolder() { ID = "ErrorMessage" }); } } }

• multiple occurences of HandleCreated for a single control

  - by Asher

  I’m using control that needs to be register to asynchronous events. The events will be raised in the UI thread using the ISynchronizeInvoke interface implemented by WinForms controls I can’t register to the event at the constructor because it will allow calling the event handler before the control is fully created. during which calls to ISynchronizeInvoke are not allowed. Solution to that problem is to use the perform the asynchronous event registration from an event handler to the HandleCreated instead of registering from the constructor. however, this poses another issue, in some scenations the HandleCreated event is raised multiple times as result of change at the control state. For example, each changing of the “RightToLeft” property causes a WMCreate message that cause raising the “HandleCreated” event. How can I prevent the multiply times of event rising? Is there is another way to know when the control is created and display for the first time? I can keep a boolean flag in the HandleCreated, however it feels like a hack and I am wondering if there is a better way to handle this issue.

• What is the motivation behind "Use Extension Methods Sparingly?"

  - by Robert Harvey

  I find them a very natural way to extend existing classes, especially when you just need to "spot-weld" some functionality onto an existing class. Microsoft says, "In general, we recommend that you implement extension methods sparingly and only when you have to." And yet extension methods form the foundation of Linq; in fact, Linq was the reason extension methods were created. Are there specific design criteria where using extension methods are perferred over inheritance or composition? Under what criteria are they discouraged?
