• Updating a listitem in an ASPX page in SharePoint Designer

  - by Andy

  Hey All, Right now I'm using SharePoint Designer to create a new aspx page. I am using a data view to display information from a list. One of the fields in the list is a choice field. I was wondering if there was anyway that I could display all of the other fields but allow one field in the list to be edited on the page without adding an edit link. Ideally, I would like a user to go in and be able to edit a field value (hopefully in a drop down list) within a data view without being redirected to the list or a form. I'm thinking there is a way to do this through javascript to embed inside the HTML or through a workflow of some sort. I'm new to javascript and don't know how to do this. I have tried to insert a drop down list and provide a data source for it but it will only show all of the field values in the list. Thus, I am unable to display the choice options, show the current value in the listitem and edit/update the listitem. Hopefully this makes sense. Can anyone help me out here? Thanks a lot, Andy

• Unsure how to design JavaScript / jQuery functionality which uses XML to create HTML objects

  - by Jack Roscoe

  Hi, I'm using JavScript and jQuery to read an XML document and subsequently use the information from the XML to create HTML objects. The main 'C' nodes in the XML document all have a type attribute, and depending on the type I want to run a function which will create a new html object using the other attributes assigned to that particular 'C' node node. Currently, I have a for loop which extracts each 'C' node from the XML and also it's attributes (e.g. width, height, x, y). Also inside the for loop, I have an if statement which checks the 'type' attribute of the current 'C' node being processed, and depending on the type it will run a different function which will then create a new HTML object with the attributes which have been drawn from the XML. The problem is that there may be more than one 'C' node of the same type, so for example when I'm creating the function that will run when a 'C' node of 'type=1' is detected, I cannot use the 'var p = document.createElement('p')' because if a 'C' node of the same type comes up later in the loop it will clash and override that element with that variable that has just been created. I'm not really sure how to approach this? Here is my entire script. If you need me to elaborate on any parts please ask, I'm sure it's not written in the nicest possible way: var arrayIds = new Array(); $(document).ready(function(){ $.ajax({ type: "GET", url: "question.xml", dataType: "xml", success: function(xml) { $(xml).find("C").each(function(){ arrayIds.push($(this).attr('ID')); }); var svgTag = document.createElement('SVG'); // Create question type objects function ctyp3(x,y,width,height,baC) { alert('test'); var r = document.createElement('rect'); r.x = x; r.y = y; r.width = width; r.height = height; r.fillcolor = baC; svgTag.appendChild(r); } // Extract question data from XML var questions = []; for (j=0; j<arrayIds.length; j++) { $(xml).find("C[ID='" + arrayIds[j] + "']").each(function(){ // pass values questions[j] = { typ: $(this).attr('typ'), width: $(this).find("I").attr('wid'), height: $(this).find("I").attr('hei'), x: $(this).find("I").attr('x'), y: $(this).find("I").attr('x'), baC: $(this).find("I").attr('baC'), boC: $(this).find("I").attr('boC'), boW: $(this).find("I").attr('boW') } alert($(this).attr('typ')); if ($(this).attr('typ') == '3') { ctyp3(x,y,width,height,baC); // alert('pass'); } else { // Add here // alert('fail'); } }); } } }); });

• Dynamic Auto updating (to UI, Grid) binding list in C# Winform?

  - by Dhana

  I'm not even sure if i'm doing this correctly. But basically I have a list of objects that are built out of a class/interface. From there, I am binding the list to a datagrid view that is on a Windows Form (C#) Here the list is a Sync list which will auto update the UI, in this case datagridview. Every thing works fine now, but now i would like to have the List should have an dynamic object, that is the object will have by default two static property (ID, Name), and at run time user will select remaining properties. These should be bind to the data grid. Any update on the list should be auto reflected in the grid. I am aware that, we can use dynamic objects, but i would like to know , how to approach for solution, datagridview.DataSource = myData; // myData is AutoUpdateList<IPersonInfo> Now IPersonInfo is the type of object, need to add dynamic properties for this type at runtime. public class AutoUpdateList<T> : System.ComponentModel.BindingList<T> { private System.ComponentModel.ISynchronizeInvoke _SyncObject; private System.Action<System.ComponentModel.ListChangedEventArgs> _FireEventAction; public AutoUpdateList() : this(null) { } public AutoUpdateList(System.ComponentModel.ISynchronizeInvoke syncObject) { _SyncObject = syncObject; _FireEventAction = FireEvent; } protected override void OnListChanged(System.ComponentModel.ListChangedEventArgs args) { try { if (_SyncObject == null) { FireEvent(args); } else { _SyncObject.Invoke(_FireEventAction, new object[] { args }); } } catch (Exception) { // TODO: Log Here } } private void FireEvent(System.ComponentModel.ListChangedEventArgs args) { base.OnListChanged(args); } } Could you help out on this?

• Creating subtree from tree which is represented in xml - python

  - by Jay

  Hi I have an XML (in the form of tree), I require to create sub-tree out of it. For ex: <a> <b> <c>Hello</c> <d> <e>Hi</e> </a> Subtree would be <root> <a> <b> <c>Hello</c> </b> </a> <a> <d> <e>Hi</e> </d> </a> </root> What is the best XML library in python to do it? Any algorithm that already does this would also be helpful. Note: the XML doc won't be that big, it will easily fit in memory.

• ROR accepts_nested_attributes_for one to many relationship with selection

  - by bilash.saha

  I have two models Doctors and Questions like the follwong: Doctor Model class Doctor < ActiveRecord::Base has_many :questions has_many :brands accepts_nested_attributes_for :questions end Question model class Question < ActiveRecord::Base belongs_to :discipline belongs_to :doctor belongs_to :brand end Now you can clearly see that Doctor has many questions and brands and question belongs to doctor and brand.I want to add previously saved question to a doctor from doctors edit page. I want to remove them as well.How can I proceed ? I tried like : <%= form.fields_for :questions, question,:child_index => (question.new_record? ?

• Java - How to declare table[i][j] elements as instance variables?

  - by JDelage

  All, I am trying to code a Connect4 game. For this, I have created a P4Game class and a P4Board class which represents the i X j dimensions of the Connect4 board. In P4Game, I have the following: public class P4Game{ //INSTANCE VARIABLES private int nbLines; private int nbColumns; private P4Board [][] position; //CONSTRUCTOR public P4Game(int nbLines, int nbColumns){ this.nbColumns = nbColumns; this.nbLines = nbLines; P4Board [][] position = new P4Board [nbLines][nbColumns]; //Creates the table to receive the instances of the P4Board object.*/ for (int i=0; i<nbLines; i++){ for (int j=0; j<nbColumns; j++){ this.position[i][j] = new P4Board(i,j); //Meant to create each object at (line=i, column=j) } } } This causes a NullPointerException in the nested loops where I mention this.position[i][j]. I reference those objects in other methods of this class so I need them to be instance variables. I suppose the exception is due to the fact that I have not listed the table element position[i][j] as an instance variable at the beginning of the class. my question to people here is (1) is my assumption correct, and if so (2) what would be the syntax to declare instance variables of this form? Thank you all for your help with what I realize is a very basic question. Hopefully it will also benefit other newbies. Cheers, JDelage

• How to prepare data for display on a silverlight chart using WCF RIA Services + Entity Framework

  - by Banford

  I've used WCF RIA services with Entity Framework to build a simple application which can display and updates data about school courses. This was done by following the Microsoft tutorials. Now I would like to have a chart which shows a count for how many courses are on a key stage. Example: Key Stage 3 - 20 courses Key Stage 4 - 32 courses Key Stage 5 - 12 courses Displayed on any form of chart. I have no problem binding data to the chart in XAML. My problem is that I do not know how to correct way of getting the data into that format. The generated CRUD methods are basic. I have a few thoughts about possible ways, but don't know which is correct, they are: Create a View in SQL server and map this to a separate Entity in the Entity Data Model. Generating new CRUD methods for this automatically. Customise the read method in the existing DomainService using .Select() .Distinct() etc. Don't know this syntax very well labda expressions/LINQ??? what is it? Any good quickstarts on it? Create a new class to store only the data required and create a read method for it. Tried this but didn't know how to make it work without a matching entity in the entity model. Something I am not aware of. I'm very new to this and struggling with the concepts so if there are useful blogs or documentation I've missed feel free to point me towards them. But I'm unsure of the terminology to use in my searches at the moment.

• A more condensed way of doing the following loop?

  - by kylex

  I have the following for-loop. It uses the values 0-6 form monday-sunday respectively. Is there a more condensed way to do this? As opposed to listing out the if ($i=="day") // $i = 0 is monday... $i = 6 is Sunday for($i=0;$i<7;$i++){ if ($i==0) echo ' <input name="repeat_on_week[]" type="checkbox" value="0" /> Monday'; if ($i==1) echo ' <input name="repeat_on_week[]" type="checkbox" value="1" /> Tuesday'; if ($i==2) echo ' <input name="repeat_on_week[]" type="checkbox" value="2" /> Wednesday'; if ($i==3) echo ' <input name="repeat_on_week[]" type="checkbox" value="3" /> Thursday'; if ($i==4) echo ' <input name="repeat_on_week[]" type="checkbox" value="4" /> Friday'; if ($i==5) echo ' <input name="repeat_on_week[]" type="checkbox" value="5" /> Saturday'; if ($i==6) echo ' <input name="repeat_on_week[]" type="checkbox" value="6" /> Sunday'; }

• rails delete_all exception

  - by Sergei

  Hello, guys! I have some User model, Role model and Assignment model to manage role-based user system. Just like here . So, here some kind of code, to include roles into users form: <% for role in Role.all %> <%= check_box_tag "user[role_ids][]", role.id, @user.roles.include?(role) %> <%=h role.name %><br /> <% end %> And all's working fine for new records and for editing records. But I just want to make possible to restrict deleting Assigment with id=1, cause this Assignment for default root user from migration, who must be admin anyway. Otherwise, I can lose my last admin. So I've tryed to add before_destroy to Assignment.rb model, but it doesn't work. I've noticed, that when I'm editing user and trying to remove his admin role(assignment), the server makes a delete_all method, not destroy method. So, does anybody know how to catch the deleting of Assignment with id=1 through this kind of code? Thanks in advance!

• What Getters and Setters should and shouldn't do.

  - by cyclotis04

  I've run into a lot of differing opinions on Getters and Setters lately, so I figured I should make it into it's own question. A previous question of mine received an immediate comment (later deleted) that stated setters shouldn't have any side effects, and a SetProperty method would be a better choice. Indeed, this seems to be Microsoft's opinion as well. However, their properties often raise events, such as Resized when a form's Width or Height property is set. OwenP also states "you shouldn't let a property throw exceptions, properties shouldn't have side effects, order shouldn't matter, and properties should return relatively quickly." Yet Michael Stum states that exceptions should be thrown while validating data within a setter. If your setter doesn't throw an exception, how could you effectively validate data, as so many of the answers to this question suggest? What about when you need to raise an event, like nearly all of Microsoft's Control's do? Aren't you then at the mercy of whomever subscribed to your event? If their handler performs a massive amount of information, or throws an error itself, what happens to your setter? Finally, what about lazy loading within the getter? This too could violate the previous guidelines. What is acceptable to place in a getter or setter, and what should be kept in only accessor methods?

• Appropriate Footwear for An Interview

  - by EoRaptor013

  There's a raging debate going on at my house about appropriate footwear for an IT interview. I have an interview, on Thursday, for a SQL/C# developer with the Fraud dept. at a large accounting firm. I was planning on wearing what I have pretty much always worn for an interview: a nice suit, white shirt, subdued tie, and a pair of dress cowboy boots. My spouse and daughter both know that my dress code for nearly every professional job I've ever gotten, is pretty much the same -- including the boots -- with what I just described. Now, however, because I've been out of work for an unfortunately long time (my last contract ended 03/09 -- pretty much coincidental with the bottom falling out of the economy). My wife insists that style standards are fundamentally different on the left side of the Mississippi vs. the right side of the river. My view is that I've always worn "cowboy" boots; since I was old enough to fit into a real pair. I moved East, as an adult, over 30 years ago, but my dress patterns haven't changed. And in all that time, my dress patterns have never changed. Now I both really want, and really need, this job. But, is that sufficient reason to change a habit 40 years in the making? I would really appreciate the thoughts ya'all (little West of Ms. colloquialism, there) might have on this matter. Thanks. P.S. If this sort of question is inappropriate for this form, I apologize.

• To OpenID or not to OpenID? Is it worth it?

  - by Eloff

  Does OpenID improve the user experience? Edit Not to detract from the other comments, but I got one really good reply below that outlined 3 advantages of OpenID in a rational bottom line kind of way. I've also heard some whisperings in other comments that you can get access to some details on the user through OpenID (name? email? what?) and that using that it might even be able to simplify the registration process by not needing to gather as much information. Things that definitely need to be gathered in a checkout process: Full name Email (I'm pretty sure I'll have to ask for these myself) Billing address Shipping address Credit card info There may be a few other things that are interesting from a marketing point of view, but I wouldn't ask the user to manually enter anything not absolutely required during the checkout process. So what's possible in this regard? /Edit (You may have noticed stackoverflow uses OpenID) It seems to me it is easier and faster for the user to simply enter a username and password in a signup form they have to go through anyway. I mean you don't avoid entering a username and password either with OpenID. But you avoid the confusion of choosing a OpenID provider, and the trip out to and back from and external site. With Microsoft making Live ID an OpenID provider (More Info), bringing on several hundred million additional accounts to those provided by Google, Yahoo, and others, this question is more important than ever. I have to require new customers to sign up during the checkout process, and it is absolutely critical that the experience be as easy and smooth as possible, every little bit harder it becomes translates into lost sales. No geek factor outweighs cold hard cash at the end of the day :) OpenID seems like a nice idea, but the implementation is of questionable value. What are the advantages of OpenID and is it really worth it in my scenario described above?

• Having trouble hiding keyboard using invisible button which sits on top of uiscrollview

  - by phil

  I have 3 items in play... 1) UIView sits at the base of the hierarchy and contains the UIScrollview. 2) UIScrollview that is presenting a lengthy user form. 3) An invisible button on the UIScrollview that I'm using to provide "hide the keyboard" features. Notice in the code below that I'm registering to be notified when the keyboard is going to appear and again when it's going to disappear. These are working great. My problem is seemingly one of "layers". See below where I insert the button into the view atIndex:0. This causes the button to be activated and "stuffed" behind the scrollview so that when you click on it, the scrollview grabs the touch and the button is unaware. There is no way to "reach" the button and suppress the keyboard. However, if I insert atIndex:1, the button gets super imposed on top of the text entry fields and so any touch at all is acted upon by the button, which immediately suppresses the keyboard and then disappears. How do I insert the button on top of the UIScrollview but behind the UITextfields that sit there? other logistics: I have a -(void) hidekeyboard function that I have setup with the UIButtion as an IBAction(). And I have the UIButton connected to "files owner" via a ctrl-drag/drop. (Do I need both of those conventions?) This code in ViewDidLoad()... [[NSNotificationCenter defaultCenter] addObserverForName:UIKeyboardWillShowNotification object:nil queue:nil usingBlock:^(NSNotification *notification){ [self.view insertSubview:self.keyboardDismissalButton atIndex:0]; }];

• jQuery UI dialog + WebKit + HTML response with script

  - by Anthony Koval'

  Once again I am faced with a great problem! :) So, here is the stuff: on the client side, I have a link. By clicking on it, jQuery makes a request to the server, gets response as HTML content, then popups UI dialog with that content. Here is the code of the request-function: function preview(){ $.ajax({ url: "/api/builder/", type: "post", //dataType: "html", data: {"script_tpl": $("#widget_code").text(), "widgets": $.toJSON(mwidgets), "widx": "0"}, success: function(data){ //console.log(data) $("#previewArea").dialog({ bgiframe: true, autoOpen: false, height: 600, width: 600, modal: true, buttons: { "Cancel": function() { $(this).dialog('destroy'); } } }); //console.log(data.toString()); $('#previewArea').attr("innerHTML", data.toString()); $("#previewArea").dialog("open"); }, error: function(){ console.log("shit happens"); } }) } The response (data) is: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript">var smakly_widget_sid = 0 ,widgets = [{"cols": "2","rows": "2","div_id": "smakly_widget","wid": "0","smakly_style": "small_image",}, ] </script> <script type="text/javascript" src="/media/js/smak/smakme.js"></script> </head> <body> preview <div id="smakly_widget" style="width:560px;height:550px"> </div> </body> </html> As you see, there is a script to load: smakme.js, somehow it doesn't execute in WebKit-based browsers (I tried in Safari and Chrome), but in Firefox, Internet Explorer and Opera it works as expected! Here is that script: String.prototype.format = function(){ var pattern = /\{\d+\}/g; var args = arguments; return this.replace(pattern, function(capture){ return args[capture.match(/\d+/)]; }); } var turl = "/widget" var widgetCtrl = new(function(){ this.render_widget = function (w, content){ $("#" + w.div_id).append(content); } this.build_widgets = function(){ for (var widx in widgets){ var w = widgets[widx], iurl = '{0}?sid={1}&wid={2}&w={3}&h={4}&referer=http://ya.ru&thrash={5}'.format( turl, smakly_widget_sid, w.wid, w.cols, w.rows, Math.floor(Math.random()*1000).toString()), content = $('<iframe src="{0}" width="100%" height="100%"></iframe>'.format(iurl)); this.render_widget(w, content); } } }) $(document).ready(function(){ widgetCtrl.build_widgets(); }) Is that some security issue, or anything else?

• Streaming content to JSF UI

  - by Mark Lewis

  Hello, I was quite happy with my JSF app which read the contents of MQ messages received and supplied them to the UI like this: <rich:panel> <snip> <rich:panelMenuItem label="mylabel" action="#{MyBacking.updateCurrent}"> <f:param name="current" value="mylog.log" /> </rich:panelMenuItem> </snip> </rich:panel> <rich:panel> <a4j:outputPanel ajaxRendered="true"> <rich:insert content="#{MyBacking.log}" highlight="groovy" /> </a4j:outputPanel> </rich:panel> and in MyBacking.java private String logFile = null; ... public String updateCurrent() { FacesContext context=FacesContext.getCurrentInstance(); setCurrent((String)context.getExternalContext().getRequestParameterMap().get("current")); setLog(getCurrent()); return null; } public void setLog(String log) { sendMsg(log); msgBody = receiveMsg(moreargs); logFile = msgBody; } public String getLog() { return logFile; } until the contents of one of the messages was too big and tomcat fell over. Obviously, I thought, I need to change the way it works so that I return some form of stream so that no one object grows so big that the container dies and the content returned by successive messages is streamed to the UI as it comes in. Am I right in thinking that I can replace the work I'm doing now on a String object with a BufferedOutputStream object ie no change to the JSF code and something like this changing at the back end: private BufferedOutputStream logFile = null; public void setLog(String log) { sendMsg(args); logFile = (BufferedOutputStream) receiveMsg(moreargs); } public String getLog() { return logFile; }

• need help with Java solution /newbie

  - by Racket

  Hi, I'm new to programming in general so i'm trying to be as specific as possible in this question. There's this book that i'm doing some exercises on. I managed to do more than half of what they say, but it's just one input that I have been struggling to find out. I'll write the question and thereafter my code, "Write an application that creates and prints a random phone number of the form XXX-XXX-XXXX. Include the dashes in the output. Do not let the first three digits contain an 8 or 9 (but don't be more restrictive than that), and make sure that the second set of three digits is not greater than 742. Hint: Think through the easiest way to construct the phone number. Each diigit does not have to be determined separately." OK, the highlighted sentence is what i'm looking at. Here's my code: import java.util.Random; public class PP33 { public static void main (String[] args) { Random rand = new Random(); int num1, num2, num3; num1 = rand.nextInt(900) + 100; num2 = rand.nextInt(643) + 100; num3 = rand.nextInt(9000) + 1000; System.out.println(num1+"-"+num2+"-"+num3); } } How am I suppose to do this? I'm on chapter 3 so we have not yet discussed if statements etcetera, but Aliases, String class, Packages, Import declaration, Random Class, Math Class, Formatting output (decimal- & numberFormat), Printf, Enumeration & Wrapper classes + autoboxing. So consider answer the question based only on these assumptions, please. The code doesn't have any errors. Thank you!

• Validations for a has_many/belongs_to relationship

  - by Craig Walker

  I have a Recipe model which has_many Ingredients (which in turn belongs_to Recipe). I want Ingredient to be existent dependent on Recipe; an Ingredient should never exist without a Recipe. I'm trying to enforce the presence of a valid Recipe ID in the Ingredient. I've been doing this with a validates :recipe, :presence => true (Rails 3) statement in Ingredient. This works fine if I save the Recipe before adding an Ingredient to it's ingredients collection. However, if I don't have explicit control over the saving (such as when I'm creating a Recipe and its Ingredients from a nested form) then I get an error: Ingredients recipe can't be blank I can get around this simply by dropping the presence validation on Ingredient.recipe. However, I don't particularly like this, as it means I'm working without a safety net. What is the best way to enforce existence-dependence in Rails? Things I'm considering (please comment on the wisdom of each): Adding a not-null constraint on the ingredients.recipe_id database column, and letting the database do the checking for me. A custom validation that somehow checks whether the Ingredient is in an unsaved recipe's ingredient collection (and thus can't have a recipe_id but is still considered valid).

• Javascript XMLHttpRequest Post method

  - by user535617

  Hey So I have a question about posting using an XMLHttpRequest. In theory, if I am to post a username and password to an https domain (which I have yet to get working, unfortunately) would the responseText then change to the next website, or should the text fields become filled in? What normally happens is you navigate to this page via browser, enter a username and password, and it uses a POST method when the submit button is clicked, doing some authentication under the hood and returning a different page. I feel like maybe the responseText should even stay exactly the same (which is what happens now), but I don't know as I have no experience with this kind of thing. this.requests[1].open("POST", "https://" + this.address, true); var query = "target=%2Fcgi-bin%2FStatusConfig.cgi%3FPage%3Dindex&userfile=&username=user&password=pass&log+in=Log+in"; this.requests[1].setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); this.requests[1].setRequestHeader("Content-length", query.length); this.requests[1].setRequestHeader("Keep-Alive", 115); this.requests[1].setRequestHeader("Connection", "keep-alive"); this.requests[1].setRequestHeader("Host", this.address); this.requests[1].send(query); this.requests[1].onreadystatechange = onReadyStateChange1; Then basically onReadyStateChange1 displays the responseText when ready. Any light that could be shed on what SHOULD be happening with the post and responseText would be very appreciated. As would any advice in getting the new, logged into page. For further clarification, what I'm trying to do is log in and then return the new page, because the login page displays only log in information/functionality and the page after logging in has a lot of relevant information. I'm not trying to check the credentials as much as I'm trying to get it (the script) to log in so it can access the next page. Granted, the credentials will have to be valid for that. Thanks all.

• Using POST or SESSION to capture data

  - by Karinne

  Hi all! I'm currently working on web application using VB in ASP.NET. Right now I have 1 page with panels that we are using to show/hide depending on the flow. When the user first comes in, he/she is presented with a gridview containing a list of clients. Then the user, clicks a link from a row and is presented a form where he/she can update the clients' info. Originally, I had a HYPERLINKFIELD that put the clientId in the url, then I'd grab the url and do the code appropriately <asp:HyperLinkField Text='<%$ Resources:Resource, ManageClient %>' DataNavigateUrlFields="CLIENT_ID" DataNavigateUrlFormatString="~/clients/manage.aspx?clientId={0}" /> Now, I'm rethinking that and wondering if it's better to use SESSIONs to grab the clientID via this instead <asp:TemplateField Visible="false"><ItemTemplate><asp:Label runat="server" ID="hidClientId" Text='<%# Bind("CLIENT_ID")%>' Visible="false" /></ItemTemplate></asp:TemplateField> <asp:ButtonField Text='<%$ Resources:Resource, ManageClient %>' CommandName="Manage" /> Or use the POST method, which I'm not sure how it works in .NET (but I've used it in PHP) Any help would be greatly appreciated.

• asp.net master page/content page interaction with style sheet

  - by Matt

  Learning how to do a master page in asp.net. Trying to figure out how my style sheet interacts with respects to the master page and content page. I can get HTML tags like body and the style sheet to react. But when I call the ID attribute of a label no styling takes place. What am I missing here as far as interaction? BTW I'm using VS2008 CSS sample: body { height:1200px; width:920px; border-style:solid; border-color:blue; padding:10px 10px 10px 10px; } #toptext1 { position:relative; top:-225px; right:-500px; font-size:22px; font-weight:bold; } From the master page: <body> <form id="form1" runat="server"> <asp:image id="cookNookLogo" ImageUrl="images/Logo.gif" runat="server" AlternateText="CookNook" Width="449px"></asp:image> <p> <asp:Label ID="toptext1" runat="server" Text="Quality Recipes, Hints and Supplies"></asp:Label> </p> From the content page: <%@ Page Language="C#" MasterPageFile="~/CNMasterPage.master" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" Title="Untitled Page" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"> <link href="App_Themes/cn/cn.css" rel="stylesheet" type="text/css" /> </asp:Content> When I was doing this without a master page it worked so where am I going wrong with the attributes?

• dynamically embedding youtube videos with jquery

  - by danwoods

  Hello all, I'm trying to retrieve a listing of a user's youtube videos and embed them in a page using jQuery. My code looks something like this: $(document).ready(function() { //some variables var fl_obj_template = $('<object width="260" height="140">' + '<param name="movie" value=""></param>' + '<param name="allowFullScreen" value="true"></param>' + '<param name="allowscriptaccess" value="always"></param>' + '<embed src="" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="260" height="140"></embed>' + '</object>'); var video_elm_arr = $('.video'); //hide videos until ready $('.video').addClass('hidden'); //pull video data from youtube $.ajax({ url: 'http://gdata.youtube.com/feeds/api/users/username/uploads?alt=json', dataType: 'jsonp', success: function(data) { $.each(data.feed.entry, function(i,item){ //only take the first 7 videos if(i > 6) return; //give the video element a flash object var cur_flash_obj = fl_obj_template; //assign title $(video_elm_arr[i]).find('.video_title').html(item.title.$t); //clean url var video_url = item.media$group.media$content[0].url; var index = video_url.indexOf("?"); if (index > 0) video_url = video_url.substring(0, index); //and asign it to the player's parameters $(cur_flash_obj).find('object param[name="movie"]').attr('value', video_url); $(cur_flash_obj).find('object embed').attr('src', video_url); //alert(cur_flash_obj); //insert flash object in video element $(video_elm_arr[i]).append(cur_flash_obj); //and show $(video_elm_arr[i]).removeClass('hidden'); }); } }); }); (of course with 'username' being the actual username). The video titles appear correctly but no videos show up. What gives? The target html looks like: <div id="top_row_center" class="video_center video"> <p class="video_title"></p> </div>

• How can I remove a JPanel from a JFrame?

  - by Roman

  Recently I asked here how to add a new JPanel to JFrame. The answer helped me to get a working code. But not I have a related question: "How can I remove an old JPanel". I need that because of the following problem. A new JPanel appears appears when I want (either time limit is exceeded or user press the "Submit" button). But in several seconds some element of the old JPanel appears together with the component of the new JPanel. I do not understand why it happens. I thought that it is because I have to other threads which update the window. But the first thread just add the old panel once (so, it should be finished). And in the second thread I have a loop which is broken (so, it also should be finished). Here is my code: private Thread controller = new Thread() { public void run() { // First we set the initial pane (for the selection of partner). SwingUtilities.invokeLater(new Runnable() { public void run() { frame.getContentPane().add(generatePartnerSelectionPanel()); frame.invalidate(); frame.validate(); } }); // Update the pane for the selection of the parnter. for (int i=40; i>0; i=i-1) { final int sec = i; SwingUtilities.invokeLater(new Runnable() { public void run() { timeLeftLabel.setText(sec + " seconds left."); } }); try {Thread.sleep(1000);} catch (InterruptedException e) {} if (partnerSubmitted) {break;} } // For the given user the selection phase is finished (either the time is over or form was submitted). SwingUtilities.invokeLater(new Runnable() { public void run() { frame.getContentPane().add(generateWaitForGamePanel()); frame.invalidate(); frame.validate(); } }); } };

• Is there a JavaScript event that fires when a tab index switch is triggered? (TABINDEX does not work for inputs in IFRAME)

  - by treeface

  My specific use case is that I have a WYSIWYG editor which is basically an editable iframe. To the user, however, it looks like a standard-issue textarea. My problem is that I have inputs that sit before and after this editor in the (perceived) tab index and I'd like the user to be able to press tab (or the equivalent on his platform of choice) to get to the WYSIWYG editor when he's in the previous element and shift-tab to get to it when he's in the latter element. I know this can be faked using the key events and checking whether or not the tab key was pressed, but I'm curious if there's a better way. UPDATE. treeface clarified the actual problem in the comments. PROBLEM: In normal case, you can use "TABINDEX" attribute of the <input> element to control that, when tabbing out of "Subject" input field (in an email form), the focus lands on "Body" input field in the e-mail. This is done simply by assigning correctly ordered values to "TABINDEX" attribute of both input fields. The problem is that TABINDEX attribute only orders elements within the same frame. So, if "Body" input field is actually in an internal IFRAME, you can't tab out of "Subject" in the parent frame straight into "Body" in the IFRAME using TABINDEX order.

• How can I send rich emails using the user's mail client ?

  - by Brann

  I need my .net program to send rich emails (usually containing table data, around 20 columns x 10 rows) using the user's mail infrastructure, allowing him to review/edit the mail before sending it, and storing the mail in his 'sent items' folder. mailto: seems the obvious choice, but unfortunately, it doesn't support neither attachments nor html bodies. It seems some clients support some extra features (e.g. Outlook 97 used to support a &Attach tag, but this is not the case for more recent versions). I could use mailto and try to format the text body to look nice (using tabs, etc), but this isn't really elegant and wouldn't support huge data. using automation seems a very huge task, as I would need to automate dozens of clients (4 or 5 versions of outlook, lotusnotes, thunderbid, etc.) ... This would be a huge task and it's not really my core business ... I could send emails through code and write my own mail form to let the user edit the mail, but this would have a lot of drawbacks : the user would need to manually configure the mail server settings he wouldn't have access to his contact directory the mail wouldn't be sent in his sent items folder This seems a quite common issue, but I haven't found any satisfying solution yet ; does someone knows of a library supporting this (ie containing automation logic for most mainstream email clients?). Or an alternative to mailto ?
