• Use AJAX to load webpage content into DIV

  - by arik-so

  Hello. I have a text field. When I type something into than text field, I want to load stuff into the DIV below. That's my code equivalent: <input type="text" onkeyup="/* I am not sure, how it's done, but I'll just write: */ document.getElementById('search_results').innerHTML = getContents('search.php?query='+this.value);" /><br/> <div id="search_results"></div> Hope you can help. Thanks in advance! EDIT: I would appreciate it if the solution did not involve using jQuery - as long as it's possible.

• HMM for perspective estimation in document image, can't understand the algorithm

  - by maximus

  Hello! Here is a paper, it is about estimating the perspective of binary image containing text and some noise or non text objects. PDF document The algorithm uses the Hidden Markov Model: actually two conditions T - text B - backgrouond (i.e. noise) It is hard to understand the algorithm itself. The question is that I've read about Hidden Markov Models and I know that it uses probabilities that must be known. But in this algorithm I can't understand, if they use HMM, how do they get those probabilities (probability of changing the state from S1 to another state for example S2)? I didn't find anything about training there also in that paper. So, if somebody understands it, please tell me. Also is it possible to use HMM without knowing the state change probabilities?

• When Drag a object from one div to another , format gets changed

  - by Anuj

  When a object is dragged and dropped from one div to another, the format in li gets changes to text only. I want it in the same format i.e 'li' after droping it. $(function() { $( "#catalog ul" ).sortable({ zIndex: 10000, revert: true }); $( "#catalog" ).accordion(); $( "#catalog ul" ).draggable({ appendTo: "body", helper: "clone", zIndex: 10000 }); $( "#dialogIteration ol" ).droppable({ activeClass: "ui-state-default", hoverClass: "ui-state-hover", drop: function( event, ui ) { $( this ).find( ".placeholder" ).remove(); $( "<li></li>" ).text( ui.draggable.text() ).appendTo( this ); } }).sortable({ items: "li:not(.placeholder)", sort: function() { // gets added unintentionally by droppable interacting with sortable // using connectWithSortable fixes this, but doesn't allow you to customize active/hoverClass options $( this ).removeClass( "ui-state-default" ); } }); $( "ul, li" ).disableSelection(); $("#dialogIteration").dialog(); }); Demo: http://jsfiddle.net/coolanuj/7683X/7/

• Why is this method executing twice each time I call it?

  - by highone

  I have the following method that is executing twice every time it is called: public static void ChangeToRepository(RepositoryTextBox textBox, int repositoryNumber) { MessageBox.Show("you"); int indexOfLastRepository = (textBox.RepositoryCollection.Count - 1); if (repositoryNumber > indexOfLastRepository) { AddTextRepositoriesThrough(textBox, repositoryNumber, indexOfLastRepository); } textBox.RepositoryCollection[textBox.CurrentRepositoryNumber].CurrentText = textBox.Text; textBox.PreviousRepositoryNumber = textBox.CurrentRepositoryNumber; textBox.CurrentRepositoryNumber = repositoryNumber; textBox.Text = textBox.RepositoryCollection[textBox.CurrentRepositoryNumber].CurrentText; } The first time that the method executes, it executes all of the code except for its last line: textBox.Text = textBox.RepositoryCollection[textBox.CurrentRepositoryNumber].CurrentText; The second time, it executes all of the code. What's up?

• JQuery $.getJSON appends a question mark to the request URL

  - by David Neale

  I have the folliwng JSON request code on an ASP.NET MVC web application: var userID = 'id=' + $('#namesList').val(); $.getJSON('/Person/GetPerson/', userID, function(data) { $('#collar').text(data.collarNumber); $('#name').text(data.Name); $('#email').text(data.EmailAddress); }); This creates a request such as: http://localhost:48610/Person/GetPerson/?id=6. Why is there a question mark in there? I get the server error The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32'.... If I make the request manually without the question mark it works fine.

• Why does it make a difference where I include the jQuery script file?

  - by Matthew Jones

  On my master page (for all pages in my site) I have a ToolkitScriptManager. On my content page, there are a series of hyperlinks and divs for collapsible functionality. The code to show/hide the panels work like the following: $('#nameHyperLink').click(function() { var div = $('#nameDiv'); var link = $('#nameHyperLink'); if (div.css('display') == 'none') { link.text('Hide Data'); div.show('100'); } else { link.text('Show Data'); div.hide('100'); } }); If I include a ScriptReference to the jQuery 1.4.2 file in the toolkitscriptmanager, the javascript code is executed incorrectly on the page (only the text for the hyperlink is changed, the div is not actually shown.) However, if I don't include the jQuery file in the ToolkitScriptManager and instead include it in the content page, it works correctly. I'm a Javascript/jQuery newbie, and this makes no sense at all. What's going on here?

• not readable PDF files

  - by Michal_R

  Hello, I am writing Master's thesis - NLP system. I have one component - extractor. It is extracting a plain text from PDF files. There are a few PDF files that can not be extracted correctly. Extractor (PDFBox library) returns a string like this: "¦xDn¦if|d+gDF"Ti&cD+lh d FÁhis~n +xd f«"d¦ffih »h" or "10a61a91a22a25a3a27a17a23a20a8a13a14a61a25a17" I was checking each file that makes this extraction's problem and all these files' text also can not be copy-pasted from PDF Reader (Adobe Reader and FoxIt reader). Viewing them in this readers is enabled, but after selecting its content and copying to the clipboard I get the same wrong text (as described above - strings of not semanticaly correct chars or strings of digits and letters) Could anybody help me??? THX :)

• Easy to follow LaTeX tutorial on layout?

  I want to layout a page using LaTeX and distribute text snippets/blocks in predefined locations.

• CheckboxList not setting Selected with Viewstate

  - by Earlz

  I have a CheckboxList that seems to load and do everything right, except for when I do a postback, it will not have the Item.Selected property set. I have viewstate disabled for the entire page. I load it like so(inside Page_Load on every load): foreach (DataRow service in d.Tables[0].Rows) { cblServices.Items.Add(new ListItem((string)service["description"], service["id"].ToString())); } My markup is simple: <asp:CheckBoxList runat="server" ID="cblServices" Width="300px"></asp:CheckBoxList> and then, I use basically something like this(in a _Click serverside event for a button) foreach(ListItem item in cblServices.Items){ if(item.Selected){ MyLabel.Text+="selected: "+item.Value+item.Text; } } and MyLabel never has any text added to it. I can verify with the debugger that it does reach the _Click's foreach loop, but no item is ever selected. What could be the cause of this?

• How to parse the MailMessage object from raw email string

  - by Xmindz

  I have written a program in C# which connects to a POP Server and retrieves raw email message strings from the server using POP3 command RETR. Since the email message being retrieved by the program is in plain text format with all the headers and message body with in the same, its too difficult to extract each header and mail body from the raw string. Could anybody tell me a solution by which I can parse the entire raw text to a System.Net.Mail.MailMessage object? Following is a sample email raw string: +OK 1281 octets Return-Path: <[email protected]> Delivered-To: samplenet-sample:[email protected] X-Envelope-To: [email protected] Received: (qmail 53856 invoked from network); 22 Sep 2012 06:11:46 -0000 Received: from mailwash18.pair.com (66.39.2.18) MIME-Version: 1.0 From: "Deepu" <[email protected]> To: [email protected] Date: 22 Sep 2012 11:41:39 +0530 Subject: TEST Subject Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: quoted-printable Message-Id: <[email protected]> TEST Body .

• Choosing http status code for unknown command reply

  - by w0rldart

  So, I'm writing a small test that I have been required to complete and I just want to give it some final touches by adding some header status code responses and some other stuff. Right now, my dilemma is what HTTP status code to choose for my "Unknown command" response after the $_GET['cmd'] has been compared to the existing commands list. case 404: $text = 'Not Found'; break; case 405: $text = 'Method Not Allowed'; break; case 406: $text = 'Not Acceptable'; break; For which one of the above should I go? And if none, which other?

• Make NSFormatter validate NSTextFieldCell continuously

  - by harms

  In Cocoa, I have an NSOutlineView where the cells are NSTextFieldCell. The cell displays values which are strings that are formatted according to certain rules (such as floats or pairs of floats with a space in between). I have made a custom NSFormatter to validate the text, and this seems to work with no problem. However, the cell (or the outline view, I'm unsure what is causing this) only seems to use the formatter at the moment my editing would end. If I type some alphabetic characters into the text field (which violates the formatting rules), these characters show up -- the only way I notice the formatter doing its job is that I'm now prevented from moving keyboard focus away from this cell. If I return the contents of the cell to a valid form, then I can move focus away. I have set both the cell and the outline view to be "continuous". It would be better if I was unable to enter text into the cell in the first place. Is it possible to make it like that, and if so, how?

• Capture and display console output at the same time

  - by Patrick

  Hi, MSDN states that it is possible in .NET to capture the output of a process and display it in the console window at the same time. Normally when you set StartInfo.RedirectStandardOutput = true; the console window stays blank. As the MSDN site doesn't provide a sample for this I was wondering if anyone would have a sample or could point me to a sample? When a Process writes text to its standard stream, that text is normally displayed on the console. By redirecting the StandardOutput stream, you can manipulate or suppress the output of a process. For example, you can filter the text, format it differently, or write the output to both the console and a designated log file. MSDN This post is similar to http://stackoverflow.com/questions/786726/capture-standard-output-and-still-display-it-in-the-console-window by the way. But that post didn't end up with a working sample. Thanks a lot, Patrick

• highlighting words at the end of a word

  - by fusion

  i'm not sure how i could have phrased the title better, but my issue is that the highlight function doesn't highlight the search keywords which are at the end of the word. for example, if the search keyword is 'self', it will highlight 'self' or 'self-lessness' or 'Self' [with capital S] but it will not highlight the self of 'yourself' or 'himself' etc. . this is my highlight function: function highlightWords($text, $words) { preg_match_all('~\w+~', $words, $m); if(!$m) return $text; $re = '~\\b(' . implode('|', $m[0]) . ')~i'; $string = preg_replace($re, '<span class="highlight">$0</span>', $text); return $string; }

• Validation Rules in Webtesting using VS2010

  - by Lexipain

  I'm creating a simple webtest (Recorded Web performance test) that makes sure that a correct error message is displayed if i try to login with a username that does not exist. However, there are two types of error messages that handle incorrect login info. One is for all the usernames that do not exist and therefore are not allowed, and the other is for usernames that start with the letter 'Q' (which is not allowed for a few reasons). Now what i want to do is use the 'Find Text' validation rule and the test should pass if ONE of the 'Find Text' parameters is found, and in that case i want the second 'Find Text' rule to be ignored so it doesn't fail the test. In other words the test should always pass if one of the 'Find Test' rules is found. How can i achieve that? Is there some if,else statement that i can use for this?
