How to create Ribbon tabs dynamically?

- by Lari13

I want to start developmet of new application using PrismV4, MEF, Ribbon. But now, I have a problem. How to create tabs for Ribbon dynamically? Each module in application could create own tab in Ribbon. And each tab may have many groups. How can it be done? Where do I need to place each group's definitions (what controls to use (buttons, textboxes, comboboxes, etc) and command bindings and how? Do I need to write XAML somewhere in Module, or all it can be done by code? And last question, how to notify Ribbon (in Shell) to add these tabs to Ribbon? Shall I use EventAggregator to communicate from Module to Shell? Or? Thanks for any advices and Happy New Year :)

A beginner's JSF question about form validation

- by Nitesh Panchal

Hello, I am having a form and many input elements in that. I want certain fields to be validated, so i keep validateLenth etc on those. And i want some fields to not be validated. For example, i have contact information and address information both on the same page. I want to treat contact information as one group. So if some fields are invalid they should not be submitted and address information to be independent of contact information. Thus, if address information is corrected it should be submitted. I have one form only on the page but two buttons, one for address and one for contact. Simply put :- What is the equivalent of validationGroup of Asp.Net in JSF?

How do I trigger a single event defined for a class of objects

- by mrbinky3000

I have a question. I have 8 buttons that have unique incrementing id's and a shared class. <button class="btnChapter" id="btnChapter_1" value="1">1</button> <button class="btnChapter" id="btnChapter_2" value="2">2</button> <button class="btnChapter" id="btnChapter_3" value="3">3</button> ... In order to prevent me from duplicating code, I bound a click event to the btnChapter class instead of binding an event individually to each button's ID. $('.btnChapter').click(function(){ .. do stuff .. }); How do I trigger() the click() event only for #btnChapter_2? The following doesn't seem to work. $('#btnChapter_2').click()

Asp.net control inside of fancybox modal is not "working"

- by studiothat

Your typical "It doesn't work" freak out going on over here. Any direction would help. I have a login control on my master page and I'm trying to only display it using jquery fancybox and then redirect the user once they are logged in. But any buttons or controls that should do "something" when pressed when I put inside the fancy box are not responding. If I keep the div visible and then use the control not using fancybox I get the expected result. What are my options?

Get Checked RadioButtons using JavaScript

- by Rudi

so I’m trying to build a win 8 app, which includes a WebView. The WebView contains the HTML code (+JavaScript) below. <!DOCTYPE HTML PUBLIC " -//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <?xml version='1.0' encoding='UTF-8' standalone='yes'?> <html> <head> <meta http-equiv='Content-Type' content='text/html; charset=utf-8' > <script type='text/javascript'> function get_radio_value() { for (var i=0; i < document.myForm.frage1.length; i++) { if (document.orderform.frage1[i].checked) { var rad_val = document.myForm.frage1[i].value; return rad_val; } } } </script> <title>Kundenfragebogen</title> </head> <body> <h1>Kundenfragebogen</h1> <div id='myDiv'>Hello</div> <form name='myForm' action=''> <table border='2'> <tr> <td></td> <td>sehr gut</td> <td>gut</td> <td>schlecht</td> </tr> <tr> <td>Wie geht es Ihnen?</td> <td><input type='radio' name="frage1" value='1'/>Mir ging es noch nie besser!</td> <td><input type='radio' name="frage1" value='2'/>Es geht mir so wie immer.</td> <td><input type='radio' name="frage1" value='3'/>Heute geht einfach gar nichts…</td> </tr> <tr> <td>Können Sie Auto fahren?</td> <td><input type='radio' name="frage2" value='1'/>Ja</td> <td></td> <td><input type='radio' name="frage2" value='3'/>Nein</td> </tr> <tr> <td>Möchten Sie unseren Newsletter abonnieren?</td> <td><input type='radio' name="frage3" value='1'/>Ja</td> <td></td> <td></td> </tr> </table> <input type='button' value='Formular absenden' onclick="return get_radio_value()"/> </form> </body> </html> So the html contains some radio buttons and a button. I’ve used JavaScript ~2 years ago (just a little), so I don’t really know how to write the exact code. I’ve found something on the internet, but it doesn’t do what I want. I want to have the following: The user can check the RadioButtons. When the user clicks the Button, the JavaScript function should return all the checked radio buttons (I only need to know which RadioButton is checked). Since I know the name of the RadioButtons in my Windows 8 App, I can do the following: var object = WebView.InvokeScript("JavaScriptFunctionNAME", NameOfRadiobutton); So the WebView invokes the script and should get as a return the VALUE of the RadioButton, which is checked. “JavaScriptFunctionNAME” = name of the function in Javascript NameOfRadiobutton = the name of the RadioButton as a parameter (for example “frage1”). Currently I’m returning the value of the radiobutton, which is checked in the RadioGroup “frage1”. How can I check every RadioButton by it’s parameter? By this I mean I have a parameter “frage1” and return the value of the checked RadioButton. After this, I call the function again with the parameter “frage2” and return the checked RadioButtons value. Could anyone help me out with the JavaScript-function?

Using static strings to define input field names in JSPs - good idea or not?

- by Derek Clarkson

Hi all, I've just be asked to work on a large portal project and have been looking through the established code. I keep finding this in the jsps: <input class="portlet-form-button" name="<%=ModifyUserProfile.FORM_FIRST_TIME_LOGIN_SUBMIT%>" type="submit" ... The authors are using static strings defined in classes to define the names of input fields and buttons in jsp forms. I've never seen this done before and was wondering if this is common practice. I'm inclined to think not, but I'm asking because, apart from centralising names which I would have thought are not likely to change, I can't see the reason why. Any thoughts on this?

MS Access - Keeping track (transacation) of all activity while form is open...

- by Ron Mac

Hi and thanks for reading. I am not a database/vba guy and my experience is strictly in the JAVA world. However, I need to have an ACCESS form open. While it is open and new data is entered into it (via the underlying query OR any other data changes in other tables based on sql updates attached to buttons on this form), is there a way that I can initiate a transaction so that at the bottom of the form I could have a button that says "Exit and committ changes" or "Cancel and Rollback changes". I guess I thought of a situation where I could do something like: On Form OPEN, START TRANSACTION On "CLICK OK", COMMIT TRANSACTION or ON "CLICK CANCEL" ROLLBACK. I'm aware how to do the Workspace.BeginTransaction but I'm not sure if that will apply if I do it on FORM OPEN and then on FORM CLOSE do the COMMIT/ROLLBACK locgin? Any insight would be great.

OpenGL and layouts

- by Hnefi

I'm using OpenGL to render a game view in my android application. The game is turn based and I wish to add some buttons to the interface. I'd prefer to use standard Android widgets, structured in an XML-generated layout (or, if I have to, a hardcoded layout) and put the OpenGL view in its own window as part of that layout. So in regards to this, I have 3 questions: 1: Is such a thing possible? I've done a few half-hearted tries, but have had no luck so far. 2: Is such a thing advisable? Does it carry a significant performance penalty, for example, over using OpenGL-based homebrew widgetry? 3: Is it possible to pass particular arguments to instances created in XML layouts? For example, my current OpenGL view has three arguments in its constructor; is it somehow possible for me to invoke that particular constructor with particular parameters when it's part of a layout?

Storing Object Types in Variable then Initializing

- by Jon Mattingly

Is there a way in Objective-C to store an object/class in a variable to be passed to alloc/init somewhere else? For example: UIViewController = foo foo *bar = [[foo alloc] init] I'm trying to create a system to dynamically create navigation buttons in a separate class based on the current view controller. I can pass 'self' to the method, but the variable that results does not allow me to alloc/init. I could always import the .h file directly, but ideally I would like to make reusing the code as simple as possible. Maybe I'm going about this the wrong way?

Audio input via HTML5?

- by tibbon

We have a VoIP application imVOX, and we are looking at various ways of expanding our reach. Part of that is writing an HTML5 application, but it requires the use of audio input from the browser (and also push to talk buttons from the browser, even if another app is focused). On the audio side, with HTML5 is there any way of taking audio input from the browser to compress and send to our servers? I know with Flash such is possible, but we're trying to avoid flash for mobile compatibility and generally looking toward the future.

[WPF] Drag and drop between 2 popups

- by timhaughton

Our application is a WPF (4.0) AppBar docked to the top of the desktop. Various buttons in the AppBar produce Popups containing various data (in ListBoxes). I am trying to implement drag and drop of items between 2 Popups. It's pretty standard boiler plate stuff using Josh Smith's draggable ListBox that I've used half a dozen times before. Drag is initiating correctly, but the target Popup is not receiving the DragOver or Drop. Is this a focus issue? Or is there something else at work here?

Self-expanding Widget, on mouse over

- by Sergiy Migdalskiy

I want to implement a widget (with some edit boxes and sliders) that would open beneath or next to a button ("Opener") when I hover it. The key is it's a temporary widget - as soon as it loses focus, I want it gone. Also, I want it to pop up right next to the Opener, ideally pointing an arrow to Opener. So, it's basically a tooltip. But it needs to be a widget with buttons and sliders and stuff like that. Is there a clever way to implement it without making a custom widget and writing handlers for all the mouse and focus events and recomputing its ideal position every time I open it or the Opener moves?

Is there a better acts_as_commentable for Rails?

- by levi rosol

Here's what I'm looking to do. I have a site where I want the user to be able to leave comments on various Models. acts_as_commentable is the obvious starting point for this, but I'm curious if there is a gem / plug-in with a more robust feature-set. For example: Pre-built partial(s) (w/ or w/o Twitter / FB buttons) Partial(s) that utilize jQuery Twitter and / or FB tunnels (push to the users twitter / FB when they comment) Pre-built mechanism for pushing other users comments to users viewing that Model I can see how some of this functionality could be app specific, however, a generic implementation seems like it would be useful. I'm curious if something like this exists or not.

Castle windsor registration

- by nivlam

interface IUserService class LocalUserService : IUserService class RemoteUserService : IUserService interface IUserRepository class UserRepository : IUserRepository If I have the following interfaces and classes, where the IUserService classes have a dependency on IUserRepository. I can register these components by doing something like: container.AddComponent("LocalUserService", typeof(IUserService), typeof(LocalUserService)); container.AddComponent("RemoteUserService", typeof(IUserService), typeof(RemoteUserService)); container.AddComponent("UserRepository", typeof(IUserRepository), typeof(UserRepository)); ... and get the service I want by calling: IUserService userService = container.Resolve<IUserService>("RemoteUserService"); However, if I have the following interfaces and classes: interface IUserService class UserService : IUserService interface IUserRepository class WebUserRepository : IUserRepository class LocalUserRepository : IUserRepository class DBUserRepository : IUserRepository How do I register these components so that the IUserService component can "choose" which repository to inject at runtime? My idea is to allow the user to choose which repository to query from by providing 3 radio buttons (or whatever) and ask the container to resolve a new IUserService each time.

UITableView performance degrading after adding subviews on cell iphone sdk

- by neha

Hi all, In my application, I'm adding a label and two buttons on cell of UItableView [I have not created a separate cell class]. I'm adding these to cell and not cell.contentview. After I run my application on IPhone, the tableview cell rendering after I move the cells up-down, is very jerky. Is it because I'm not adding the views on cell.contentView or because I've not created a custom class for cell? Can anybody please help? Thanks in advance.

n how to show cascade windows in Splitcontainer panel2 c#

- by user1875373

In MdiParent toolstripmenuItem, I'm writing the code to show all the windows in cascade or Tile Horizontal style. My code is: this.LayoutMdi(MdiLayout.Cascade); this.LayoutMdi(MdiLayout.TileHorizontal); This code will work in mdi parent only. But now I'm using a Split container in my Parent Form. In Panel1 I have buttons to Show the Form. In Panel2 My Forms will display, as: Forms.paymentPaid paidFm = new SalesandPurchases.Forms.paymentPaid(); paidFm.MdiParent = this; paidFm.Left = (this.myPanel.Width - paidFm.Width) / 2; paidFm.Top = (this.myPanel.Height - paidFm.Height) / 2; myPanel.Controls.Add(paidFm); paidFm.Show(); Now Because of my Split Container my code( this.LayoutMdi(MdiLayout.Cascade)) is not working for cascade the windows in Panel2. Please tell me any other way.

Best Practice: Accessing radio button group

- by seth

Looking for the best, standards compliant, cross browser compatible, forwards compatible way to access a group of radio buttons in the DOM (this is closely related to my other most recent post...), without the use of any external libraries. <input type="radio" value="1" name="myRadios" />One<br /> <input type="radio" value="2" name="myRadios" />Two<br /> I've read conflicting information on getElementsByName(), which seems like the proper way to do this, but I'm unclear if this is a standards compliant, forwards compatible solution. Perhaps there is a better way?

Rewriting URL in AJAX application

- by Artem Moskalev

I am making a simple online application. I have a navigation bar with a few buttons and one "div" into which all the new contents will be loaded dynamically i.e. when I click "About", it will load the page parts into the "div" without reloading the whole page with .load() function. The problem is: what if I need to give a link to the Documents section of my web site, or the user wants to store this kind of link, the url is not rewritten when browsing my site. when the user stores the default link it will always link him to the default "Home" part. How can I rewrite the URL and what is the most correct way to do this?

Get a single element with PHP and XPath

- by daliz

Lots of tutorials around the net but none of them can explain me this: How do I select a single element (in a table, for example), having its absolute XPath? Example: I have this: /html/body/table/tbody/tr[2]/td[2]/table/tbody/tr/td/table[3]/tbody/tr/td/table/tbody/tr[3]/td/table/tbody/tr[4]/td[5]/span What's that PHP function to get the text of that element?! Really I could not find an answer. Found lots of guides and hints to get all the elements of the table, all the buttons of a form, etc, but not what I need. Thank you.
