Why does fb:fan control disappear after login with requireSession on external page?

- by Max

Hi, Reqs: I want to make an external page with a 'Become a Fan'-button. I want users to login to facebook once they open the page (this is because of other features in the site) So I call FB.Connect.requireSession once the page loads, and put a <fb:fan></fb:fan> control on the page. Then when I open the page I see the 'Connect with Facebook to Continue' pop-up and a small 'Become a fan' button. This seems right. When I log in to Facebook using the pop-up the 'Become a fan button' disappears!! Can anyone explain this weird behaviour or does someone know a way to reach my requirements in a different way. Below you can see my code. Thanks in advance!  <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/nl_NL" type="text/javascript"></script> <script type="text/javascript"> var fbApiKey = "MY_KEY"; var fbXdReceiver = "xd_receiver.htm"; function fbLoad() { FB.init(fbApiKey, fbXdReceiver); FB.ensureInit(function() { FB.Connect.requireSession(null, null, false); }); } </script>  <fb:fan profile_id="24932281961" name="Nutella" id="fanButton" stream="0" connections="0" logobar="0" width="250"></fb:fan>

Any guidelines for handling the Headset and Bluetooth AVRC transport controls in Android 2.2

- by StefanK

I am trying to figure out what is the correct (new) approach for handling the Intent.ACTION_MEDIA_BUTTON in Froyo. In pre 2.2 days we had to register a BroadcastReceiver (either permanently or at run-time) and the Media Button events would arrive, as long as no other application intercepts them and aborts the broadcast. Froyo seems to still somewhat support that model (at least for the wired headset), but it also introduces the registerMediaButtonEventReceiver, and unregisterMediaButtonEventReceiver methods that seem to control the "transport focus" between applications. During my experiments, using registerMediaButtonEventReceiver does cause both the bluetooth and the wired headset button presses to be routed to the application's broadcast receiver (the app gets the "transport focus"), but it looks like any change in the audio routing (for example unplugging the headset) shits the focus back to the default media player. What is the logic behind the implementation in Android 2.2? What is correct way to handle transport controls? Do we have to detect the change in the audio routing and try to re-gain the focus? This is an issue that any 3rd party media player on the Android platform has to deal with, so I hope that somebody (probably a Google Engineer) can provide some guidelines that we can all follow. Having a standard approach may make headset button controls a bit more predictable for the end users. Stefan

[IE6] Cannot upload non-existent file

- by geff_chang

I am asking the same question as this: http://stackoverflow.com/questions/691323/trying-to-upload-a-non-existent-file-in-internet-explorer-form-is-not-submitted I'm not sure if the topic starter found a solution, since he did not post the answer. So, I'd like to ask you guys this question again. I have type=input in my form, and a submit button. If I type garbage input into the textbox (like the text "abc") in the file control's textbox, and click the submit button, the form is not submitted to the server. AND, no feedback is given to the user. Instead of this "Is-the-submit-button-broken?" behavior, is there a way I could notify the user that the file does not exist? (I am aware this is not possible, except with ActiveX, but I don't want to go into that) My client wants to hide the textbox of the file control, but I'm not sure if this is a good design. What do you guys suggest? (If it makes any difference, I am also using this jquery plugin: http://www.fyneworks.com/jquery/multiple-file-upload/)

Radio buttons change variable in JavaScript

- by dmanexe

I have two fields which calculate a total, but I have a radio button pair that determines a variable within the equation. Here's the radio button code: <input type="radio" name="estimate_pool_shape" value="1" /> Angle <input type="radio" name="estimate_pool_shape" value=".86392" /> Freeform Immediately after that, this JavaScript is then calculating the surface area of the pool based of these fields and script: (Length <input type="text" size="5" name="estimate_pool_length" onBlur="conv2inches(document.forms.mainform);" />) x (Width <input type="text" name="estimate_pool_width" size="5" onBlur="conv2inches(document.forms.mainform);" />) The following JavaScript already works to update the fields, I just need the variable it uses to set the field values to change based on the radio buttons. function conv2inches(mainform) { var oin; var oinches; if(isNaN(mainform.estimate_pool_width.value)||isNaN(mainform.estimate_pool_length.value)){ alert("Please enter numbers only"); return false; } oin = ((mainform.estimate_pool_width.value) + (mainform.estimate_pool_length.value) * %%%RADIO BUTTON VARIABLE HERE%%%); oinches = (oin); if(oinches==0){ alert("Please enter valid values into the boxes"); } mainform.estimate_pool_sqft.value = oinches; return false; }

History.js not working in Internet Explorer

- by Wilcoholic

I am trying to get history.js to work in Internet Explorer because I need history.pushState() to work. I have read over the instructions on GitHub (https://github.com/balupton/History.js/) and have tried implementing it, but havent had any success.

Any help is appreciated

How to make BoxLayout vertical but children flow top-aligned?

- by user291701

I'm trying to get get a vertical, top-aligned layout to work. This is what I have: JPanel pane = new JPanel(); pane.setLayout(new BoxLayout(pane, BoxLayout.Y_AXIS)); MyImagePanel panelImage = new MyImagePanel(); panelImage.setSize(400, 400); pane.add(new JComboBox()); pane.add(panelImage); pane.add(new JButton("1")); pane.add(new JButton("2")); pane.add(new JButton("3")); JFrame frame = new JFrame("Title"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(800, 600); frame.add(pane); frame.pack(); frame.setVisible(true); All the controls appear, but it looks like padding is being applied at run time between their tops and bottoms so they're somewhat vertically centered. This is what I'm going for: ----------------------------------------------------- | ComboBox | | ------------ | | | | | Image | | | | | ------------ | | Button 1 | Any additional space fills the right | ------------ | | Button 2 | | ------------ | | Button 3 | | ------------ | | | | Any additional space fills the bottom | | | ----------------------------------------------------- How do I get BoxLayout to do that? Thanks ------------------------- Update ------------------------- Was able to use this: Box vertical = Box.createVerticalBox(); frame.add(vertical, BorderLayout.NORTH); vertical.add(new JComboBox()); vertical.add(new JButton("1")); ... to get what I wanted.

UINavigationController from scratch?

- by Moshe

I have a view based app that works well. (In other words, I'm not going to start over with a Navigation-Based App template.) It's an immersive app of sorts and I'm trying to add a Table View that loads in a new view when a button is pressed. The loading the nib part works, but I can't seem to be able to add a navigation controller to the new view. I want to see a navigation bar on top with a done button and an edit button. Also, I want to the Table View entries to be empty. I added a new file like so: File-> New File -> UINavigationController subclass. I checked the UITableViewController Subclass and With XIB for user interface. All I see when the view is pulled up is a blank Table View. I am able to customize things in the view controller. What can I do to make the table show a navigation bar and be editable? I need some direction here please. EDIT: I'm working with the latest Public SDK. (XCode 3.2.2)

WP7: Why does a ListBox.ItemsPanel break my ElementName data binding?

- by iguanaNet

I have a Windows Phone 7 ListBox that binds to a list of integers. I am using the default MVVM Light template, so there is a ViewModel class that contains data and a simple RelayCommand. Here is the ListBox: <ListBox ItemsSource="{Binding MyData}"> <ListBox.ItemTemplate> <DataTemplate> <Button Content="{Binding}"> <i:Interaction.Triggers> <i:EventTrigger EventName="Click"> <cmd:EventToCommand Command="{Binding ElementName=ContentGrid, Path=DataContext.TestCommand}" CommandParameter="{Binding}" /> </i:EventTrigger> </i:Interaction.Triggers> </Button> </DataTemplate> </ListBox.ItemTemplate> </ListBox> This displays a vertical list of integers inside buttons. If you click any of them, the following command code executes and shows a pop-up: new RelayCommand<int>(i => MessageBox.Show("Test" + i)); However, if I simply add the following XAML to change to a horizontal list, the databinding fails. Nothing happens when you click the button and no error messages are written to the Output window. <ListBox.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" /> </ItemsPanelTemplate> </ListBox.ItemsPanel> I have tried some other types of binding for the EventToCommand. For example, specifying my ViewModel as a static resource. It works, but is less ideal than the example above. Why does that ItemsPanel break the databinding?

Prototype: Form.serialize missing some inputs (due to table?)

- by Chris

I'm using JavaScript Prototype (through Ruby on Rails) to handle some Ajax calls; but in one particular case I'm missing a field from the form. I have a layout like this: +---------+---------+ | Thing 1 | Thing 2 | +---------+---------+-----------+ | o Opt 1 | o Opt 1 | <Confirm> | | o Opt 2 | o Opt 2 | | +---------+---------+-----------+ Opt 1 and 2 are Radio buttons, Confirm is a button. The entire table is wrapped in a form, with code like: <form action="javascript:void(0)"> <input type="hidden" name="context" value="foo" /> <input type="hidden" name="subcontext" value="bar" /> <table> <tr><td>Thing 1</td><td>Thing2</td></tr> <tr><td> <input type="radio" name="choice" value="1.1" />Opt 1<br /> <input type="radio" name="choice" value="1.2" />Opt 2<br /> </td><td> <input type="radio" name="choice" value="2.1" />Opt 1<br /> <input type="radio" name="choice" value="2.2" />Opt 2<br /> </td><td> <input name="choice_btn" type="button" value="Confirm" onclick="new AJAX.Updater('my_form', '/process_form', {asynchronous:true, evalScripts:true, parameters:Form.serialize(this.form)}); return false;" /> </td></tr> </table> </form> But I can see that the POST generated by clicking the Confirm button contains the foo and bar values for the hidden fields, but not the choice of the radio buttons. Is this because I've got a table inside my form? How can I get around this?

In Firefox, how to bring an existing popup window with multiple tabs to the front using javascript f

- by brahn

I would like to have a button on a web page with the following behavior: On the first click, open a pop-up. On later clicks, if the pop-up is still open, just bring it to the front. If not, re-open. The below code generally works in Firefox, Safari, and IE8 (see here for Chrome woes). However, I have found a failure mode in Firefox that I don't know how to deal with: If for some reason the user has opened a second tab in the pop-up window and that second tab has focus within that window, the popupWindow.focus() command fails to have any effect. (If the first tab has focus within that window, everything works just great.) So, how can I focus the popup and the desired tab in Firefox? <head> <script type="text/javascript"> var popupWindow = null; var doPopup = function () { if (popupWindow && !popupWindow.closed) { popupWindow.focus(); } else { popupWindow = window.open("http://google.com", "_blank", "width=200,height=200"); } }; </script> </head> <body> <button onclick="doPopup(); return false"> create a pop-up </button> </body> Background: I am re-asking this question specifically for Google Chrome, as I think I my code solves the problem at least for other modern browsers and IE8. If there is a preferred etiquette for doing so, please let me know.

Adding new records in Access without wrecking the form

- by Matt Parker

I'm working on a simple Access 2003 application to keep track of things that need to be done for clients for some colleagues. Each colleague has a set of clients, and each client has a set of actions that need to be taken by a certain date. I've set up a form that consists of a combobox for client ID (indexed), a drop-down for the person who is handling that client's case, and a button for adding new clients (a standard Access-created Add Record button). The actions are listed in a subform below these three elements. The problem I've run into is that the first person I tested this on clicked the button to add a new record, then didn't fill it out and tried to select another client from the drop-down list. Access interprets this as an attempt to set the selected Client ID as the ID for the new record and rightfully throws an error for duplicate primary keys. I can think of a couple of ways around this problem, but I'd much rather hear your elegant solutions than kludge together some junk in a language I don't know. Let me know if you have any questions. Thank you.

Jquery animate negative top and back to 0 - starts messing up after 3rd click

- by Daniel Takyi

The site in question is this one: http://www.pickmixmagazine.com/wordpress/ When you click on one of the posts (any of the boxes) an iframe will slide down from the top with the content in it. Once the "Home" button in the top left hand corner of the iframe is clicked, the iframe slides back up. This works perfectly the first 2 times, on the 3rd click on of a post, the content will slide down, but when the home button is clicked, the content slides back up normally but once it has slid all the way up to the position it should be in, the iframe drops straight back down to where it was before the home button was clicked, I click it again and then it works. Here is the code I've used for both sliding up and sliding down functions: /* slide down function */ var $div = $('iframe.primary'); var height = $div.height(); var width = parseInt($div.width()); $div.css({ height : height }); $div.css('top', -($div.width())); $('.post').click(function () { $('iframe.primary').load(function(){ $div.animate({ top: 0 }, { duration: 1000 }); }) return false; }); /* slide Up function */ var elm = parent.document.getElementsByTagName('iframe')[0]; var jelm = $(elm);//convert to jQuery Element var htmlElm = jelm[0];//convert to HTML Element $('.homebtn').click(function(){ $(elm).animate({ top: -height }, { duration: 1000 }); return false; })

paypal_adaptive gem in Rails: Dynamic Receiver "Population" (Chained Payments)

- by Jmlevick

Note: I didn't find a better title for this O.o Hello, Humm... Look, what I want to do is to have a Rails app where a visitor can click a button/link to make a "special" chained payment using Paypal; Currently I have a Users registration form that has one field for the user to enter his/her paypal account email, and as I saw here: http://marker.to/XGg9MR it is possible to specify the primary reciever and the secondary ones by adding such info in a controller action when using the paypal_adaptive gem in a rails app. The thing is, I don't want to hard code the secondary reciever as I need to specify a different secondary reciever from time to time, (being specific my primary reciever will always be the same, but depending on what button/link the visitor clicks, the secondary one is going to change) and I want that secondary reciever email to be the paypal e-mail account from one of the registered users when the visitor clicks on their specific button/link... My question is: Is it possible to create such enviroment functionality in my app using the current implementation of the paypal_adaptive gem? Could someone point me in the right direction on how to accomplish such thing? I'm still learning rails and also I'm really new in the paypal handling universe with this framework! XD P.S. Thanks! :)

ASP .NET: Cannot call Page WebMethod using jQuery

- by John

I created a WebMethod in the code-behind file of my page as such: [System.Web.Services.WebMethod()] public static string Test() { return "TEST"; } I created the following HTML page to test it out: <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"/></script> <script type="text/javascript"> function test() { $.ajax({ type: "POST", url: "http://localhost/TestApp/TestPage.aspx/Test", data: "{}", contentType: "application/json; charset=utf-8", dataType: "text", success: function(msg) { alert(msg.d); } }); } </script> </head> <body> <button onclick="test();">Click Me</button> </body> </html> When I click the button, the AJAX fires off, but nothing is returned. When I debug my code, the method Test() doesn't even get called. Any ideas?

Dismiss android activity displayed as Popup

- by Sit

So i have a service, that starts an activity displayed as a Popup thank's to "android:style/Theme.Dialog" This Activity shows a Listview, with a list of application. On each element of the listview, there is a short description of the application, and two buttons. 1 for launching the application 2 for displaying a toast with more informations. Here is the code in my service : it starts the activity Intent intent = new Intent(this, PopUpActivity.class); intent.addFlags(Intent.FLAG_DEBUG_LOG_RESOLUTION); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); getApplicationContext().startActivity(intent); this activity uses a custom layout, with a listview, adapted with a custom ArrayAdapter In this adaptater, i've put an action on the start button in order to start the current application Button lanceur = (Button) v.findViewById(R.id.Buttonlancer); lanceur.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { p.start(mcontext); } }); with p.start, i start the application. But now, if i press "back" from the application, i go back to the popup... and i can start another application. I don't want it to be possible. That's why i wish i could dismiss/destroy/finish my PopupActivity, but i can't manage to do it with the code i have.

Not Understanding Basics Of Dynamic DataBinding (bindPropety) In Flex

jQuery and executing code until mouseout is called

- by Tomaszewski

Good day all, I am tasked with building a slider for our site. Here is my goal: <div id="abc"> <div id="slider">...</div> </div> I need to move "slider" left 30px at a time when a button is hovered over, and right 30px when another button is hovered over. My problem is that there doesn't seem to be a reliable method for telling the code that the mouse hasn't left the are in question, unless there is something I did not think about or read yet. In other words, when the mouse is OVER the a button, the code to move "slider" left is executed until the mouseout is called. I'm not really sure how to do this. The only way I can think of is to look at the offsetTop and offsetLeft and offsetTop DOM properties and compare them to the mouse position, than run checks to see if the mouse is within the bounds of the box, and if not than it will stop the execution of code. Is there a better way to do this?

Debug.Assert-s use the same error message. Should I promote it to a static variable?

- by Hamish Grubijan

I love Asserts and code readability but not code duplication, and in several places I use a Debug.Assert which checks for the same condition like so: Debug.Assert(kosherBaconList.SelectedIndex != -1, "An error message along the lines - you should not ever be able to click on edit button without selecting a kosher bacon first."); This is in response to an actual bug, although the actual list does not contain kosher bacon. Anyhow, I can think of two approaches: private static readonly mustSelectKosherBaconBeforeEditAssertMessage = "An error message along the lines - you should not ever be able to " + "click on edit button without selecting a something first."; ... Debug.Assert( kosherBaconList.SelectedIndex != -1, mustSelectKosherBaconBeforeEditAssertMessage) or: if (kosherBaconList.SelectedIndex == -1) { AssertMustSelectKosherBaconBeforeEdit(); } ... [Conditional("DEBUG")] private void AssertMustSelectKosherBaconBeforeEdit() { // Compiler will optimize away this variable. string errorMessage = "An error message along the lines - you should not ever be able to " + "click on edit button without selecting a something first."; Debug.Assert(false, errorMessage); } or is there a third way which sucks less than either one above? Please share. General helpful relevant tips are also welcome.

I have assigned the 80% height of the viewport to my div as height. In Button click i have displayed the height of the div. This works fine in ie9, ie10. But in ie7, ie8 $("#divContainer").height() is 0. Am i doing anything wrong and how to get the height of the div in IE7, IE8(vml) <html style="height:100%;"> <body style="height:100%;"> <div id="divContainer" style="height:100%; border:2px solid #ff0000"> </div> <button id="button1"></button> <script type="text/javascript"> $(function () { $("#button1").click(function() { alert($("#divContainer").height()); }); }); </script> </body> </html> Thanks In Advance

Appended content using jQuery 'append' is not submitted?

- by YourMomzThaBomb

I'm new to jQuery so this may be a real simple answer. I have a ASP.NET project that I'm trying to dynamically add content to a span element by typing into a text box and clicking a button. Sounds simple right? Well, I can get the content to added, but when the form is submitted the span element is still empty? Why is the new data not submitted? What step am I missing? Please help. Here's some sample code: < span id="tagContainer" runat="server"< /span < input type="text" name="tag" id="tag" / < input type="button" name="AddTag" value="Add" class="button" onclick="addTag();" / function addTag() { if ($("#tag").val() != "") { $("#tagContainer").append('$("#tag").val()'); $("#tag").val(""); } }
