• Can i use microsoft ajax tab controls SKIN only ?

  - by Anil Namde

  I like YUI's Tab, to use its look and feel for own tab like implementation we just have to include yui tabs CSS and use markups and css classes and done. example below, <link rel="stylesheet" type="text/css" href="http://yui.yahooapis.com/2.8.0r4/build/tabview/assets/skins/sam/tabview.css" /> <ul class="yui-nav"> <li><a href="#tab1"><em>Tab One Label</em></a></li> <li class="selected"><a href="#tab2"><em>Tab Two Label</em></a></li> <li><a href="#tab3"><em>Tab Three Label</em></a></li> </ul> Now i have a site where Microsort's tab tab controls are used and there are some which are old simple tabs. Now i would like to change these old tabs to Microsoft tab structures just by using CSS if possible as we have done above for YUI. Is that possible to do that using CSS/file? How it can be done for Microsofts tab?

• F# Inline Function Specialization

  - by Ben

  Hi, My current project involves lexing and parsing script code, and as such I'm using fslex and fsyacc. Fslex LexBuffers can come in either LexBuffer<char> and LexBuffer<byte> varieties, and I'd like to have the option to use both. In order to user both, I need a lexeme function of type ^buf - string. Thus far, my attempts at specialization have looked like: let inline lexeme (lexbuf: ^buf) : ^buf -> string where ^buf : (member Lexeme: char array) = new System.String(lexbuf.Lexeme) let inline lexeme (lexbuf: ^buf) : ^buf -> string where ^buf : (member Lexeme: byte array) = System.Text.Encoding.UTF8.GetString(lexbuf.Lexeme) I'm getting a type error stating that the function body should be of type ^buf -> string, but the inferred type is just string. Clearly, I'm doing something (majorly?) wrong. Is what I'm attempting even possible in F#? If so, can someone point me to the proper path? Thanks!

• How can I force a jQuery faded-in user control to remain after click events?

  - by David

  I have a basic page to which I'm adding an uploader control based on Bulk Uploader at c-sharpcorner.com and the control is in a jQuery-faded div based on yesdegisn The Bulk Uploader has two server side event handlers for two buttons--Add and Remove. After clicking these buttons, the fade disappears and you're back to the basic page--if the user needs to add more files, this is not desirable. The ArrayList of files added to a ListBox is maintained, but I have to click the "fade-in" link (LinkButton id="lnkDocumentUpload") to display this window again. I also need the control to POST to UploadPost.aspx, and it doesn't work either. Clicking the upload button(<asp:Button ID="btnUpload" runat="server" />) has the same behavior described above--fade disappears, data is retained, and no POST. I've surrounded the control with <form id="frmUpload" action="~/UploadPost.aspx"> ... <asp:Button ID="btnUpload" runat="server" Text="Upload"/> </form> A LinkButton activates the fade in jQuery via $("#lnkDocumentUpload").click(function() { centerPopup(); loadPopup(); });

• Browser Compatibility of IE7 and IE8

  - by Kamlesh

  Hi, I am working on a project, in which I am particularly using the CSS with themes. I am facing a compatibility problem between IE7 and IE8. I have placed a ASP.Net menu on page in <div>. Applying CSS style on the div as follows. .TopMenuPanel {           background-color:#3783a9;           position:relative;           left:597px;           top:0px;           width:573px;           height:24px;           text-align:left center; } When I am seeing the page on IE7, the menu showing in one position whereas in IE8 it is showing in another position. Specific talking, in IE7, on the position of Left:597px Top:0px it is showing in before the half page, and in IE8 it is showing after the half page. Anybody else have any experience of such a problem, then please give me the expert solution on this problem.

• How to fetch and populate backbone model for Google Places JS API?

  - by code-gijoe

  I'm implementing a system that require access to Google Places JS API. I've been using rails for most of the project, but now I want to inject a bit of AJAX in one of my views. Basically it is a view that displays places near your location. For this, I'm using the JS API of Google places. A quick workflow would be: 1- The user inputs a text query and hits enter. 2- There is an AJAX call to request data from Google Places API. 3- The successful result is presented to the user. The problem is primarily in step 2. I want to use backbone for this but when I create a backbone model, it requests to the 'rootURL'. This wouldn't be a problem if the requests to Places was done from the server but it is not. A place call is done like this: service = new google.maps.places.PlacesService(map); service.nearbySearch(request, callback); Passing a callback function: function callback(results, status) { if (status == google.maps.places.PlacesServiceStatus.OK) { for (var i = 0; i < results.length; i++) { var place = results[i]; createMarker(results[i]); } } } Is it possible to override the 'fetch' method in backbone model and populate the model with the successful Places result? Is this a bad idea?

• Z-index broken in IE8?

  - by Anna

  Hi there This code works in every other browser I've tried, except IE8. IE8 appears to ignore the z-index - and the pop-up becomes a pop-under. It's in the right place, just renders underneath the thumbnail. Anyone? Thanks! HTML: <a class="thumbnail" href="#thumb"> <img src="/images/comic_a3_thumb.jpg" height="300" width="212" border="0" style="float:right; margin-top:10px;margin-bottom:10px;" alt="description" /> <span> <img src="/images/comic_a3_popup.jpg" /> /span> </a> CSS: .thumbnail{ position: relative; z-index: 0; } .thumbnail:hover{ background-color: transparent; z-index: 50; } .thumbnail span{ /*CSS for enlarged image*/ position: absolute; background-color: lightyellow; padding: 5px; left: 0px; border: 1px dashed gray; visibility: hidden; color: black; text-decoration: none; } .thumbnail span img{ /*CSS for enlarged image*/ border-width: 0; padding: 2px; } .thumbnail:hover span{ /*CSS for enlarged image on hover*/ visibility: visible; top: -140px; /*position where enlarged image should offset horizontally */ left: -500px; }

• Read file:// URLs in IE XMLHttpRequest

  - by Dan Fabulich

  I'm developing a JavaScript application that's meant to be run either from a web server (over http) or from the file system (on a file:// URL). As part of this code, I need to use XMLHttpRequest to load files in the same directory as the page and in subdirectories of the page. This code works fine ("PASS") when executed on a web server, but doesn't work ("FAIL") in Internet Explorer 8 when run off the file system: <html><head> <script> window.onload = function() { var xhr = new XMLHttpRequest(); xhr.open("GET", window.location.href, false); xhr.send(null); if (/TestString/.test(xhr.responseText)) { document.body.innerHTML="<p>PASS</p>"; } } </script> <body><p>FAIL</p></body> Of course, at first it fails because no scripts can run at all on the file system; the user is prompted a yellow bar, warning that "To help protect your security, Internet Explorer has restricted this webpage from running scripts or ActiveX controls that could access your computer." But even once I click on the bar and "Allow Blocked Content" the page still fails; I get an "Access is Denied" error on the xhr.open call. This puzzles me, because MSDN says that "For development purposes, the file:// protocol is allowed from the Local Machine zone." This local file should be part of the Local Machine Zone, right? How can I get code like this to work? I'm fine with prompting the user with security warnings; I'm not OK with forcing them to turn off security in the control panel. EDIT: I am not, in fact, loading an XML document in my case; I'm loading a plain text file (.txt).

• Ajax UpdatePanels SetFocus issue

  - by George

  I set the AutoPostback property of a textbox to True so I can process the TextChanged event on the server and, based on what they typed in the textbox, appropriately display a message in an update panel. The problem is, when the partial screen refresh is performed, no control on the screen has focus. 99% of the time, when the text in the textbox is changed, it is because the user has tabbed forward, and so, to limit the disruption in the lost of focus, I perform a "Focus" call on teh next control in the tab sequence. For the most part, this works OK, but of course, is disputive if the user is tabbing in the reverse order or has used the mouse to set the focus to another control. In these situations, the focus would be set to the next control even though the user was trying to set focus elsewhere. OK, that sucks. Now what I consider the bigger problem with calling the focus method on the server: In IE, it works OK, but in Mozilla Firefox and Chrome, setting the focus causes a repositioning of the scroll bar, even though none is necessary because the control is already in view. I realize that I could switch to doing AJAX web service calls, but these darn Updae Panels are so convenient if used in moderation. is there anyway to use updatepanels and not have these focus/scroll issues?

• get html content of a page with Silverlight

  - by Yustme

  Hi, I'm trying to get the html content of a page using silverlight. Webresponse and request classes don't work in silverlight. I did some googling and I found something. This is what i tried: public partial class MainPage : UserControl { string result; WebClient client; public MainPage() { InitializeComponent(); this.result = string.Empty; this.client = new WebClient(); this.client.DownloadStringCompleted += ClientDownloadStringCompleted; } private void btn1_Click(object sender, RoutedEventArgs e) { string url = "http://www.nu.nl/feeds/rss/algemeen.rss"; this.client.DownloadStringAsync(new Uri(url, UriKind.Absolute)); if (this.result != string.Empty && this.result != null) { this.txbSummery.Text = this.result; } } private void ClientDownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { this.result = e.Result; //handle the response. } } It gives me a runtime error after pressing the button: Microsoft JScript runtime error: Unhandled Error in Silverlight Application An exception occurred during the operation, making the result invalid. Check InnerException for exception details. at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary() at System.Net.DownloadStringCompletedEventArgs.get_Result() at JWTG.MainPage.ClientDownloadStringCompleted(Object sender, DownloadStringCompletedEventArgs e) at System.Net.WebClient.OnDownloadStringCompleted(DownloadStringCompletedEventArgs e) at System.Net.WebClient.DownloadStringOperationCompleted(Object arg) I've tried numerous things but all failed. What am i missing? Or does anyone know how i could achieve this in a different way? Thanks in advance!

• How do you manually set a RadioGroup value in wicket?

  - by Kane

  I'm trying to change the selected radio button in a Wicket RadioGroup during an AjaxEventBehavior but can't figure out how to do so. Specifically when a user types some text in a textbox I want to change the selected radio button to one I specify. How do you do this? Here's what I have so far (it crashes on addComponent): myRadioGroup = new RadioGroup("MyNewGroup", new PropertyModel(getPojo(), "selectedGroup")); Radio internalRadio = new Radio("InternalDirectoryNumber", new Model("Internal")); myRadioGroup .add(internalRadio); Radio externalRadio = new Radio("OtherMobileNumber", new Model("External")); myRadioGroup .add(externalRadio); TextField myTxtField= new TextField("TextBoxPrivateNumber", new PropertyModel(getVoiceItem(), "privateMobilePhone")); myTxtField.add( new AjaxEventBehavior( "onKeyUp" ) { @Override protected void onEvent(AjaxRequestTarget target) { Component component = target.getPage().get("myForm:MyNewGroup").setDefaultModelObject("External"); target.addComponent(component); //this causes an exception } }); myRadioGroup .add(myTxtField); Here is the exception that's thrown. java.lang.IllegalArgumentException: cannot update component that does not have setOutputMarkupId property set to true. Component: [MarkupContainer [Component id = myRadioGroup]] What's the proper way to do this? I'm not finding a whole lot of wicket documentation for this online.

• jQuery UI selectable won't work with anything besides '#selectable'

  - by Ross Murphy

  I am trying to use 2 instances of the jquery selector UI on my site and it won't seem to work with anything besides '#selectable' as the ordered list id. Here is my code.. <script type="text/javascript"> $(document).ready(function() { $("#selectable").selectable(); }); </script> <ol id="selectable"> <li class="ui-widget-content">Item 1</li> <li class="ui-widget-content">Item 2</li> <li class="ui-widget-content">Item 3</li> <li class="ui-widget-content">Item 4</li> <li class="ui-widget-content">Item 5</li> <li class="ui-widget-content">Item 6</li> <li class="ui-widget-content">Item 7</li> </ol> But if i try to use something other than selectable, it doesn't work.. anyone have similar issues?

• Several Objective-C objects become Invalid for no reason, sometimes.

  - by farnsworth

  - (void)loadLocations { NSString *url = @"<URL to a text file>"; NSStringEncoding enc = NSUTF8StringEncoding; NSString *locationString = [[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:url] usedEncoding:&enc error:nil]; NSArray *lines = [locationString componentsSeparatedByString:@"\n"]; for (int i=0; i<[lines count]; i++) { NSString *line = [lines objectAtIndex:i]; NSArray *components = [line componentsSeparatedByString:@", "]; Restaurant *res = [byID objectForKey:[components objectAtIndex:0]]; if (res) { NSString *resAddress = [components objectAtIndex:3]; NSArray *loc = [NSArray arrayWithObjects:[components objectAtIndex:1], [components objectAtIndex:2]]; [res.locationCoords setObject:loc forKey:resAddress]; } else { NSLog([[components objectAtIndex:0] stringByAppendingString:@" res id not found."]); } } } There are a few weird things happening here. First, at the two lines where the NSArray lines is used, this message is printed to the console- *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFDictionary count]: method sent to an uninitialized mutable dictionary object' which is strange since lines is definitely not an NSMutableDictionary, definitely is initialized, and because the app doesn't crash. Also, at random points in the loop, all of the variables that the debugger can see will become Invalid. Local variables, property variables, everything. Then after a couple lines they will go back to their original values. setObject:forKey never has an effect on res.locationCoords, which is an NSMutableDictionary. I'm sure that res, res.locationCoords, and byId are initialized. I also tried adding a retain or copy to lines, same thing. I'm sure there's a basic memory management principle I'm missing here but I'm at a loss.

• Prevent default on a click within a JQuery tabs in Google Chrome.

  - by Sydney

  I would like to prevent the default behaviour of a click on a link. I tried the return false; also javascript:void(0); in the href attribute but it doesn’t seem to work. It works fine in Firefox, but not in Chrome and IE. I have a single tab that loads via AJAX the content which is a simple link. <script type="text/javascript"> $(function() { $("#tabs").tabs({ ajaxOptions: { error: function(xhr, status, index, anchor) { $(anchor.hash).html("Couldn't load this tab. We'll try to fix this as soon as possible. If this wouldn't be a demo."); }, success: function() { alert('hello'); $('#lk').click(function() { alert('Click Me'); return false; }); } }, load: function(event, ui) { $('a', ui.panel).click(function() { $(ui.panel).load(this.href); return false; }); } }); }); </script> <body> <div id="tabs"> <ul> <li><a href="linkChild.htm">Link</a></li> </ul> </div> </body> The content of linkChild.htm is <a href="javascript:void(0)" id="lk">Click Me</a> So basically when the tab content is loaded with success, a click event is attached to the link “lk”. When I click on the link, the alert is displayed but then link disappears. I check the HTML and the element is actually removed from the DOM.

• Is there a way to increase performance on my simple textfilter?

  - by djerry

  Hey guys, I'm writing a filter that will pick out items. I have a list of Objects. The objects contain a number, name and some other irrelevant items. At the moment, the list contains 200 items. When typing in a textbox, i'm looking if the string matches a part of the number/name of the objects in the list. If so, add them to the listbox. Here's the code for my textbox textchanged event : private void txtTelnumber_TextChanged(object sender, TextChangedEventArgs e) { lstOverview.Items.Clear(); string data = ""; foreach (ucTelListItem telList in _allUsers) { data = telList.User.H323 + telList.user.E164; if (data.Contains(txtTelnumber.Text)) lstOverview.Items.Add(telList); } } I sometimes see a little delay when entering a character, especially when i go from 4 records to 200 records (so when i had a filter and 4 records matched, and i backspace and the whole list appears again). My list is a list of usercontrols, cause i found it takes less time to load the usercontrols from a list, then to have to initialize a new usercontrol each time. Can i do something about the code, or is it just adding the usercontrol the listbox that causes the small delay (small delay = <1 sec)? Thanks in advance.

• Please critique this method

  - by Jakob

  Hi I've been looking around the net for some tab button close functionality, but all those solutions had some complicated eventhandler, and i wanted to try and keep it simple, but I might have broken good code ethics doing so, so please review this method and tell me what is wrong. public void AddCloseItem(string header, object content){ //Create tabitem with header and content StackPanel headerPanel = new StackPanel() { Orientation = Orientation.Horizontal, Height = 14}; headerPanel.Children.Add(new TextBlock() { Text = header }); Button closeBtn = new Button() { Content = new Image() { Source = new BitmapImage(new Uri("images/cross.png", UriKind.Relative)) }, Margin = new Thickness() { Left = 10 } }; headerPanel.Children.Add(closeBtn); TabItem newTabItem = new TabItem() { Header = headerPanel, Content = content }; //Add close button functionality closeBtn.Tag = newTabItem; closeBtn.Click += new RoutedEventHandler(closeBtn_Click); //Add item to list this.Add(newTabItem); } void closeBtn_Click(object sender, RoutedEventArgs e) { this.Remove((TabItem)((Button)sender).Tag); } So what I'm doing is storing the tabitem in the btn.Tag property, and then when the button is clicked i just remove the tabitem from my observablecollection, and the UI is updated appropriately. Am I using too much memory saving the tabitem to the Tag property?

• How to best future proof my application that needs to connect to Outlook?

  - by Troy

  I have a contact management application written in Delphi which has a “Sync with Outlook” feature that I developed 10 years ago. Now, I’m going back to add some features and fix some bugs. This sync feature uses the Outlook object model to get started, but it has an optional mode called “Use MAPI Enhancements” where it uses pure MAPI to speed up how it looks for changes, and it allows notes to be synced w/ RTF instead of just plain text. I'm wondering if supporting two parallel paths of execution is a good idea or not. If I went with all MAPI, I believe I'd avoid some security prompts, and I'd avoid situations where anti-virus has "script-blocking" features which block my app from connecting to Outlook. But I believe that on the down side, my 32-bit app would not be able to to connect with 64-bit Outlook 2010 using MAPI. And I wonder about the future of MAPI in general. If I stick with the Outlook object model, will my 32-bit app be able to connect to the Outlook object model (since it's out of process COM)? If so, this is a compelling reason to keep my Outlook object model execution path in place. But if not, and if my app needs to be compiled for x64, then why not just go with pure MAPI?

• Does anyone knows the algorithm how Facebook detects the images when adding a link

  - by Edelcom

  When you add a link to your Facebook page, after some processing, Facebook presents you a next/prev button to choose an image linked to the url your are inserting. Obviously, Facebook reads the html-page and displays the images found on the url you insert. Does anyone knows what algorithm Facebook uses to decide what images to show ? If I insert a link to : http://www.staplijst.be/lachende-wandelaars-aalter-aktivia-003.asp, only 11 images are detected. The one I want, the one at the top right corner, is not included in the list. If I insert a link to http://www.staplijst.be/stichting-kennedymars-rijsbergen-zundert-nederland-knblo-nl-81996.asp, 19 images are displayed (including the one I want (the one at the right top corner of the text area). Both pages are build using asp code but are functionally the same. I thought that it has something to do with the image size, but can't find any deciding factor there. I will investigate some furhter, because if I know what Facebook is looking for, I can make sure that the correct images are included on the page (since they are dynamic pages build with classic asp). But if anyone has any idea ? Help would be appreciated.

• C#: Wrong answer when finding "cool" numbers.

  - by user300484

  Hello you all! In my application, a "cool" number is a number that is both a square and a cube, like for example: 64 = 8^2 and 64 = 4^3. My application is supposed to find the number of "cool numbers" between a range given by the user. I wrote my code and the application runs fine, but it is giving me the wrong answer. Can you help me here please? for example: IMPUT 1 100 OUTPUT 1 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { double a = Convert.ToDouble(Console.ReadLine()); // first number in the range double b = Convert.ToDouble(Console.ReadLine()); // second number in the range long x = 0; for (double i = a; i <= b; i++) { double cube = 1.0 / 3.0; double cuad = 1.0 / 2.0; double crt = Math.Pow(i, cube); // cube root double sqrt = Math.Pow(i, cuad); // square root if ((crt * 10) % 10 == 0 || (sqrt * 10) % 10 == 0) // condition to determine if it is a cool number. x++; } Console.WriteLine(x); Console.ReadLine(); } } }

• Updating progress dialog in Activity from AsyncTask

  - by Laimoncijus

  In my app I am doing some intense work in AsyncTask as suggested by Android tutorials and showing a ProgressDialog in my main my activity: dialog = ProgressDialog.show(MyActivity.this, "title", "text"); new MyTask().execute(request); where then later in MyTask I post results back to activity: class MyTask extends AsyncTask<Request, Void, Result> { @Override protected Result doInBackground(Request... params) { // do some intense work here and return result } @Override protected void onPostExecute(Result res) { postResult(res); } } and on result posting, in main activity I hide the dialog: protected void postResult( Result res ) { dialog.dismiss(); // do something more here with result... } So everything is working fine here, but I would like to somehow to update the progress dialog to able to show the user some real progress instead just of dummy "Please wait..." message. Can I somehow access the progress dialog from MyTask.doInBackground, where all work is done? As I understand it is running as separate Thread, so I cannot "talk" to main activity from there and that is why I use onPostExecute to push the result back to it. But the problem is that onPostExecute is called only when all work is already done and I would like to update progress the dialog in the middle of doing something. Any tips how to do this?

• Search and highlight html - ignoring and maintaining tags

  - by Sleepwalker

  I am looking for a good way to highlight key words in a block of html with stripping the html tags. I can regex to search for key words within html tags, but I haven't found a great way to search across tags. For example, if the key word phrase is "not bound" I want to be able to make this <p>I am not<strong>bound to please thee</strong> with my answers.</p> become wrapped in highlight tags, without breaking the "strong" tag (and making the html invalid) and become: <p>I am <span class="highlight">not</span><strong><span class="highlight">bound</span> to please thee</strong> with my answers.</p> The main issue is maintaining the html as it is AND wrapping blocks of text with highlight tags. I need to maintain the original html. Otherwise I would strip the tags. The best solution to this that I can think of right now would entail making a copy of the html and placing counter tokens where each space occurs, then stripping all tags and search for matching phrases, then looking back to the original and the tokenized strings and figuring out where to start building the highlight tags, then start walking forward, starting and ending highlight spans as needed from the beginning of the match until the end. This seems like overkill. I would like to something more elegant if possible. The solution would be written in C# or perhaps javascript, depending.

I have a superclass of Communications with subclasses of Call, Text, and Data. I'm hitting a snag with properly populating these tables so that I can find the appropriate data in the various tables. My Types and Tables are declared as such: create type CommunicationType as object ( -- column names here ) not final; create type CallType under CommunicationType ( -- column names here ); create type TextType under CommunicationType ( -- column names here ); create type DataType under CommunicationType ( -- column names here ); create table Communications of CommunicationType ( -- Primary and Foreign key constraints here ); create table Calls of CallType; create table Texts of TextType; create table Datas of DataType; When I try to insert data into one of the subclasses, its entry doesn't appear in the superclass. Likewise if I insert into the superclass, it doesn't show up in the appropriate subclass. For example, insert into Calls values (CallType( -- Values -- )); doesn't show any data in Communications. Nor does insert into Communications values (CallType( -- Values -- )); show anything in Calls. What am I doing wrong?

• How do I update a progress bar in Cocoa during a long running loop?

  - by Nic

  Hi, I've got a while loop, that runs for many seconds and that's why I want to update a progress bar (NSProgressIndicator) during that process, but it updates only once after the loop has finished. The same happens if I want to update a label text, by the way. I believe, my loop prevents other things of that application to happen. There must be another technique. Does this have to do with threads or something? Am I on the right track? Can someone please give me a simple example, how to “optimize” my application? My application is a Cocoa Application (Xcode 3.2.1) with these two methods in my Example_AppDelegate.m: // This method runs when a start button is clicked. - (IBAction)startIt:(id)sender { [progressbar setDoubleValue:0.0]; [progressbar startAnimation:sender]; running = YES; // this is a instance variable int i = 0; while (running) { if (i++ = processAmount) { // processAmount is something like 1000000 running = NO; continue; } // Update progress bar double progr = (double)i / (double)processAmount; NSLog(@"progr: %f", progr); // Logs values between 0.0 and 1.0 [progressbar setDoubleValue:progr]; [progressbar needsDisplay]; // Do I need this? // Do some more hard work here... } } // This method runs when a stop button is clicked, but as long // as -startIt is busy, a click on the stop button does nothing. - (IBAction)stopIt:(id)sender { NSLog(@"Stop it!"); running = NO; [progressbar stopAnimation:sender]; } I'm really new to Objective-C, Cocoa and applications with a UI. Thank you very much for any helpful answer.
