• e4x filter on more then on childeren?

  My XML Looks like this: <?xml version="1.0" encoding="utf-8" ?> <projects> <project id="1" thumb="media/images/thumb.jpg" > <categories> <id>1</id> <id>2</id> </categories> <director>Director name</director> <name><![CDATA[IPhone commercial]]></name> <url><![CDATA[http://www.iphone.com]]></url> <description><![CDATA[Description about the project]]></description> <thumb><![CDATA[/upload/images/thumb.jpg]]></thumb> </project> </projects> But I cannot figure out how to filter projects based on a category id?

• Problem writing a snippet containing Emacs Lisp code

  - by user388346

  Hi all, I've been trying to make use of a cool feature of YASnippet: write snippets containing embedded Emacs Lisp code. There is a snippet for rst-mode that surrounds the entered text with "=" that is as long as the text such as in ==== Text ==== Based on this snippet, I decided to slightly modify it (with Elisp) so that it comments out these three lines depending on the major mode you are in (I thought that such a snippet would be useful to organize the source code). So I wrote this: ${1:`(insert comment-start)`} ${2:$(make-string (string-width text) ?\-)} $1 ${2:Text} $1 ${2:$(make-string (string-width text) ?\-)} $0 This code works relatively well except for one problem: the indentation of these three lines gets mixed up, depending on the major mode I'm in (e.g., in emacs-lisp-mode, the second and the third lines move more to the right than the first line). I think the source of the problem might have something to do with what comes after the string ${1: on the first line. If I add a character, I have no problem (i.e., all three lines are correctly aligned at the end of the snippet expansion). If I add a single space after this string, the misalignment problem still continues though. So my question is: do you know of any way of rewriting this snippet so that this misalignment does not arise? Do you know what's the source of this behaviour? Cheers,

• The Implications of Modern Day Software Development Abstractions

  - by Andreas Grech

  I am currently doing a dissertation about the implications or dangers that today's software development practices or teachings may have on the long term effects of programming. Just to make it clear: I am not attacking the use abstractions in programming. Every programmer knows that abstractions are the bases for modularity. What I want to investigate with this dissertation are the positive and negative effects abstractions can have in software development. As regards the positive, I am sure that I can find many sources that can confirm this. But what about the negative effects of abstractions? Do you have any stories to share that talk about when certain abstractions failed on you? The main concern is that many programmers today are programming against abstractions without having the faintest idea of what the abstraction is doing under-the-covers. This may very well lead to bugs and bad design. So, in you're opinion, how important is it that programmers actually know what is going below the abstractions? Taking a simple example from Joel's Back to Basics, C's strcat: void strcat( char* dest, char* src ) { while (*dest) dest++; while (*dest++ = *src++); } The above function hosts the issue that if you are doing string concatenation, the function is always starting from the beginning of the dest pointer to find the null terminator character, whereas if you write the function as follows, you will return a pointer to where the concatenated string is, which in turn allows you to pass this new pointer to the concatenation function as the *dest parameter: char* mystrcat( char* dest, char* src ) { while (*dest) dest++; while (*dest++ = *src++); return --dest; } Now this is obviously a very simple as regards abstractions, but it is the same concept I shall be investigating. Finally, what do you think about the issue that schools are preferring to teach Java instead of C and Lisp ? Can you please give your opinions and your says as regards this subject? Thank you for your time and I appreciate every comment.

• Calling subactivity from subactivity

  I have three activities in my android app. First activity is main application screen which gives option to open second screen containing second activity. But when I click on the button on second activity which was supposed to open third activity screen, I get "Application has stopped unexpectedly" error. <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="org.anddev.android.SampleApp" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".FirstActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".SecondActivity" android:label="@string/app_name" > </activity> <activity android:name=".ThirdActivity" android:label="@string/app_name" > </activity> </application>

• [Javascript] Linux Ajax (mootools Request.JSON) Header error

  - by VDVLeon

  Hi all, I use the following code to get some json data: var request = new Request.JSON( { 'url': sourceURI, 'onSuccess': onPageData } ); request.get(); Request.JSON is a class from Mootools (a javascript library). But on linux (ubuntu on firefox 3.5 and Chrome) the request always fails. So i tried to display the http request ajax is sending. (I used netcat to display it) The request is like this: OPTIONS /the+url HTTP/1.1 Host: example.com Connection: keep-alive User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/532.3 (KHTML, like Gecko) Chrome/4.0.226.0 Safari/532.3 Referer: http://example.com/ref...

• Why Illegal cookies are send by Browser and received by web servers (rfc2109)?

  - by Artyom

  Hello, According to RFC 2109 cookie's value can be either HTTP token or quoted string, and token can't include non-ASCII characters. Cookie's RFC 2109: http://tools.ietf.org/html/rfc2109#page-3 HTTP's RFC 2068 token definition: http://tools.ietf.org/html/rfc2068#page-16 However I had found that Firefox browser (3.0.6) sends cookies with utf-8 string as-is and three web servers I tested (apache2, lighttpd, nginx) pass this string as-is to the application. For example, raw request from browser: $ nc -l -p 8080 GET /hello HTTP/1.1 Host: localhost:8080 User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.9) Gecko/2009050519 Firefox/2.0.0.13 (Debian-3.0.6-1) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: windows-1255,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Cookie: wikipp=1234; wikipp_username=?????? Cache-Control: max-age=0 And raw response of apache, nginx and lighttpd HTTP_COOKIE CGI variable: wikipp=1234; wikipp_username=?????? What do I miss? Can somebody explain me?

• How to use Caret to tell which line it is in from JTextPane? (Java)

  - by Alex Cheng

  Hi all. Problem: I have CaretListener and DocumentListener listening on a JTextPane. I need an algorithm that is able to tell which line is the caret at in a JTextPane, here's an illustrative example: Result: 3rd line Result: 2nd line Result: 4th line and if the algorithm can tell which line the caret is in the JTextPane, it should be fairly easy to substring whatever that is in between the parentheses as the picture (caret is at character m of metadata): -- This is how I divide the entire text that I retrieved from the JTextPane into sentences: String[] lines = textPane.getText().split("\r?\n|\r", -1); The sentences in the textPane is separated with \n. Problem is, how can I manipulate the caret to let me know at which position and which line it is in? I know the dot of the caret says at which position it is, but I can't tell which line it is at. Assuming if I know which line the caret is, then I can just do lines[<line number>] and manipulate the string from there. In Short: How do I use CaretListener and/or DocumentListener to know which line the caret is currently at, and retrieve the line for further string manipulation? Please help. Thanks. Do let me know if further clarification is needed. Thanks for your time.

• Is this a bug or something I am doing wrong?

  - by Brian Gideon

  I cannot imagine how this is anything other than a bug, but since I do not currently have a login for the MS Connect website I will ask here first. I have Visual Studio 2008 SP 1 with all post SP1 hotfixes I could find relating to the crash installed. Can you reproduce the following crash? 1) Create a new "WPF Application" project using VB as the language (though I suspect it will happen in C# as well). 2) Enter the following code in the Window1.xaml.vb file. Friend MustInherit Class A End Class Friend MustInherit Class A(Of T) Inherits A End Class 3) Add a namespace declaration the Window1.xaml file so that it looks like the following. <Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300"> <Grid> </Grid> </Window> 4) Now attempt to edit the xaml file by opening a new xml tag via the < character. 5) CRASH! Edit: Microsoft has confirmed this bug. The issue still exists in VS2010 beta 2, but will be fixed in the next release.

• Programmatically downloaded file is larger than it should be

  - by Dan Revell

  I'm trying to download a file from SharePoint. The file itself is an InfoPath template although this is probably inconsequential. If I put the url into internet explorer and save the file to disk, it comes in at 4.47KB and works correctly. If I try to download from the same Url in code the it comes back as 21.9KB and is corrupt. Why it's coming down as corrupt I'm trying to work out. The following are two ways of downloading the file that both produce the corrupt file at 21.9KB: /// web client { WebClient wc = new WebClient(); wc.Credentials = CredentialCache.DefaultCredentials; wc.DownloadFile(templateUri, file); byte[] bytes = wc.DownloadData(templateUri); } /// web request { WebRequest request = WebRequest.Create(templateUri); request.Credentials = CredentialCache.DefaultCredentials; WebResponse responce = request.GetResponse(); StreamReader sr = new StreamReader(responce.GetResponseStream()); byte[] bytes = System.Text.Encoding.UTF8.GetBytes(sr.ReadToEnd()); } And this is how I write the data to disk using (FileStream fs = new FileStream(file, FileMode.Create, FileAccess.Write)) { fs.Write(bytes, 0, bytes.Length); }

• How to Declare Complex Nested C# Type for Web Service

  - by TheArtTrooper

  I would like to create a service that accepts a complex nested type. In a sample asmx file I created: [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. // [System.Web.Script.Services.ScriptService] public class ServiceNest : System.Web.Services.WebService { public class Block { [XmlElement(IsNullable = false)] public int number; } public class Cell { [XmlElement(IsNullable = false)] public Block block; } public class Head { [XmlElement(IsNullable = false)] public Cell cell; } public class Nest { public Head head; } [WebMethod] public void TakeNest(Nest nest) { } } When I view the asmx file in IE the test page shows the example SOAP post request as: <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <TakeNest xmlns="http://schemas.intellicorp.com/livecompare/"> <nest> <head> <cell> <block xsi:nil="true" /> </cell> </head> </nest> </TakeNest> </soap:Body> </soap:Envelope> It hasn't expanded the <block> into its number member. Looking at the WSDL, the types all look good. So is this just a limitation of the post demo page creator? Thanks.

• Using Pastebin API in Node.js

  - by wiill

  I've been trying to post a paste to Pastebin in Node.js, but it appears that I'm doing it wrong. I'm getting a Bad API request, invalid api_option, however I'm clearly setting the api_option to paste like the documentation asks for. var http = require('http'); var qs = require('qs'); var query = qs.stringify({ api_option: 'paste', api_dev_key: 'xxxxxxxxxxxx', api_paste_code: 'Awesome paste content', api_paste_name: 'Awesome paste name', api_paste_private: 1, api_paste_expire_date: '1D' }); var req = http.request({ host: 'pastebin.com', port: 80, path: '/api/api_post.php', method: 'POST', headers: { 'Content-Type': 'multipart/form-data', 'Content-Length': query.length } }, function(res) { var data = ''; res.on('data', function(chunk) { data += chunk; }); res.on('end', function() { console.log(data); }); }); req.write(query); req.end(); console.log(query) confirms that the string is well encoded and that api_option is there and set to paste. Now, I've been searching forever on possible causes. I also tried setting the encoding on the write req.write(query, 'utf8') because the Pastebin API mentions that the POST must be UTF-8 encoded. I rewrote the thing over and over and re-consulted the Node HTTP documentation many times. I'm pretty sure I completely missed something here, because I don't see how this could fail. Does anyone have an idea of what I have done wrong?

• python gui events out of order

  - by dave

  from Tkinter import * from tkMessageBox import * class Gui: def __init__(self, root): self.container = Frame(root) self.container.grid() self.inputText = Text(self.container, width=50, height=8) self.outputText = Text(self.container, width=50, height=8, bg='#E0E0E0', state=DISABLED) self.inputText.grid(row=0, column=0) self.outputText.grid(row=0, column=1) self.inputText.bind("<Key>", self.translate) def translate(self, event): input = self.inputText.get(0.0, END) output = self.outputText.get(0.0, END) self.outputText.config(state=NORMAL) self.outputText.delete(0.0, END) self.outputText.insert(INSERT, input) self.outputText.config(state=DISABLED) showinfo(message="Input: %s characters\nOutput: %s characters" % (len(input), len(input))) root = Tk() #toplevel object app = Gui(root) #call to the class where gui is defined root.mainloop() #enter event loop Working on a gui in tkinter I'm a little confused as to the sequence the event handlers are run. If you run the above code you'll hopefully see... 1) Editing the text widget triggers the event handler but it seems to fire it off without registering the actual change, 2) Even when the text widget is cleared (ie, keep pressing BackSpace) it still seems to have a one character length string, 3) The output widget only receives its update when the NEXT event trigger is fired despite the fact the data came on the previous event. Is this just how bindings work in tkinter or am i missing something here? The behaviour i would like when updating the input widget is: 1) Show the change, 2) Enter event handler, 3) Update output widget, 4) Show message box.

• Creating a simple command line interface (CLI) using a python server (TCP sock) and few scripts

  - by VN44CA

  I have a Linux box and I want to be able to telnet into it (port 77557) and run few required commands without having to access to the whole Linux box. So, I have a server listening on that port, and echos the entered command on the screen. (for now) Telnet 192.168.1.100 77557 Trying 192.168.1.100... Connected to 192.168.1.100. Escape character is '^]'. hello<br /> You typed: "hello"<br /> NOW: I want to create lot of commands that each take some args and have error codes. Anyone has done this before? It would be great if I can have the server upon initialization go through each directory and execute the init.py file and in turn, the init.py file of each command call into a main template lib API (e.g. RegisterMe()) and register themselves with the server as function call backs. At least this is how I would do it in C/C++. But I want the best Pythonic way of doing this. /cmd/ /cmd/myreboot/ /cmd/myreboot/ini.py (note underscore don't show for some reason) /cmd/mylist/ /cmd/mylist/init.py ... etc IN: /cmd/myreboot/_ini_.py: from myMainCommand import RegisterMe RegisterMe(name="reboot",args=Arglist, usage="Use this to reboot the box", desc="blabla") So, repeating this creates a list of commands and when you enter the command in the telnet session, then the server goes through the list, matches the command and passed the args to that command and the command does the job and print the success or failure to stdout. Thx

• Silverlight Socket Constantly Returns With Empty Buffer

  - by Benny

  I am using Silverlight to interact with a proxy application that I have developed but, without the proxy sending a message to the Silverlight application, it executes the receive completed handler with an empty buffer ('\0's). Is there something I'm doing wrong? It is causing a major memory leak. this._rawBuffer = new Byte[this.BUFFER_SIZE]; SocketAsyncEventArgs receiveArgs = new SocketAsyncEventArgs(); receiveArgs.SetBuffer(_rawBuffer, 0, _rawBuffer.Length); receiveArgs.Completed += new EventHandler<SocketAsyncEventArgs>(ReceiveComplete); this._client.ReceiveAsync(receiveArgs); if (args.SocketError == SocketError.Success && args.LastOperation == SocketAsyncOperation.Receive) { // Read the current bytes from the stream buffer int bytesRecieved = this._client.ReceiveBufferSize; // If there are bytes to process else the connection is lost if (bytesRecieved > 0) { try { //Find out what we just received string messagePart = UTF8Encoding.UTF8.GetString(_rawBuffer, 0, _rawBuffer.GetLength(0)); //Take out any trailing empty characters from the message messagePart = messagePart.Replace('\0'.ToString(), ""); //Concatenate our current message with any leftovers from previous receipts string fullMessage = _theRest + messagePart; int seperator; //While the index of the seperator (LINE_END defined & initiated as private member) while ((seperator = fullMessage.IndexOf((char)Messages.MessageSeperator.Terminator)) > 0) { //Pull out the first message available (up to the seperator index string message = fullMessage.Substring(0, seperator); //Queue up our new message _messageQueue.Enqueue(message); //Take out our line end character fullMessage = fullMessage.Remove(0, seperator + 1); } //Save whatever was NOT a full message to the private variable used to store the rest _theRest = fullMessage; //Empty the queue of messages if there are any while (this._messageQueue.Count > 0) { ... } } catch (Exception e) { throw e; } // Wait for a new message if (this._isClosing != true) Receive(); } } Thanks in advance.

• Image overlapping in widget

  - by Hunt

  I am trying to create a widget in android in which when I click over image the image gets changed with a new one -- kind of toggle image. But when I click over it, the image overwrites over the old one rather then replacing the new one. I don't know whether this is the way the widget works or am I doing something wrong. My images are semi-transparent so in case one overrides another one can see the image which is being overlapped. This is the code that I have written in OnReceive by overriding it: @Override public void onReceive(Context context, Intent intent){ if (intent.getAction().equals(iAlertConstant.ACTION_WIDGET_UPDATE_FROM_WIDGET)) { RemoteViews remoteViews = new RemoteViews(context.getPackageName(),R.layout.mywidget); remoteViews.setImageViewResource(R.id.btnOnOff,R.drawable.offbtn); ComponentName thisWidget = new ComponentName(context, EmergencyWidget.class); AppWidgetManager.getInstance(context).updateAppWidget(thisWidget, remoteViews); } else super.onReceive(context, intent); } Layout <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:background="@drawable/widget_background" android:paddingLeft="10.0dip" android:paddingTop="8.0dip" android:paddingRight="10.0dip" android:paddingBottom="8.0dip" android:layout_width="fill_parent" android:layout_height="72dp" android:layout_marginLeft="10.0dip" android:layout_marginTop="10.0dip" android:layout_marginRight="10.0dip" android:id="@+id/emergencyWidget" android:orientation="horizontal"> <ImageView android:background="@drawable/offbtn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="7dp" android:layout_marginLeft="4dp" android:layout_marginRight="4dp" android:layout_gravity="right" android:id="@+id/btnOnOff" /> </LinearLayout>

• Why am I losing my characters from my html string when trying to add html dynamically using javascri

  - by Hamman359

  I have a page that I am trying to dynamically add some links to. The links are getting added to the page fine, but the '[' and ']' at either end of the line are getting dropped. The code from my .js file is: var html = "[ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove </a> ]"; $(html).appendTo("#id123"); The result I want is: [ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove</a> ] The result I'm getting is: <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove</a> If I wrap the line in a <span> tag like so: var html = "<span>[ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove </a> ]</span>"; $(html).appendTo("#id123"); it renders as expected. I set a breakpoint on the code and checked the html var right before the .appendTo and it contains the '[' and ']'. Anyone know why this is happening? Are '[' and ']' special character that need escaped and I'm just forgetting that fact?

• How do I serialize an enum value as an int?

  - by Espo

  I want to serialize my enum-value as an int, but i only get the name. Here is my (sample) class and enum: public class Request { public RequestType request; } public enum RequestType { Booking = 1, Confirmation = 2, PreBooking = 4, PreBookingConfirmation = 5, BookingStatus = 6 } And the code (just to be sure i'm not doing it wrong) Request req = new Request(); req.request = RequestType.Confirmation; XmlSerializer xml = new XmlSerializer(req.GetType()); StringWriter writer = new StringWriter(); xml.Serialize(writer, req); textBox1.Text = writer.ToString(); This answer (to another question) seems to indicate that enums should serialize to ints as default, but it doesn't seem to do that. Here is my output: <?xml version="1.0" encoding="utf-16"?> <Request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <request>Confirmation</request> </Request> I have been able to serialize as the value by putting an "[XmlEnum("X")]" attribute on every value, but this just seems wrong.

• How to vertically align text in a button with a background drawable?

  - by neutrino

  I had a simple button set up with a background image defined like android:background="?attr/button" where ?attr/button was a reference to a simple 9-patch png. Everything worked fine, text in the button was aligned correctly. Then I needed to have a different background for a pressed state of the button. So I changed that to android:background="@drawable/state_button" where @drawable/state_button is an xml with the following states <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:drawable="@drawable/button_pressed" /> <!-- pressed --> <item android:state_focused="true" android:drawable="@drawable/button_pressed" /> <!-- focused --> <item android:drawable="@drawable/button" /> <!-- default --> </selector> And after that I can't align the text properly. If I put android:gravity="center_vertical" the text is drawn about 1/4 of the button height from the top. I double-checked my 9-patch images, everything seems fine with them. And I also tried having regular pngs for the background, it also doesn't change anything.

• Strange behaviour with PHP/Pear HTML_Quickform and Firfox 3.6

  - by chessweb

  I am using PHP/Pear HTMLQuickForm and HTMLQuickForm_Controller to do some stuff with HTML-forms. Then I noticed that certain phone numbers would not be displayed even though the data had been loaded correctly. I boiled it down to the following rather strange phenomenons that have me completely baffled: $this->addElement('static', null, 'Telefon:', '04556-8978765'); will just show "Telefon:" in Firefox 3.6. In IE8 I see "Telefon: 04556-8978765" as expected. $this->addElement('static', null, 'Telefon:', '904556-8978765'); displays just "Telefon: 9" in Firefox 3.6 and correctly "Telefon: 904556-8978765" in IE8. On the other hand $this->addElement('static', null, 'Telefon:', '099828-67776554'); shows "Telefon: 099828-67776554" in both browsers. So my question is this: What is so special about the string 04556-8978765 that Firefox 3.6 refuses to render it? And it gets even weirder: The string 0208-23345 and 02232-12345 have the same problem, but when I prefix them with any other character, then unlike 04556-8978765 they are displayed alright. And it is not as if the missing strings are not rendered at all. On page reload I see them for a short time and then they disappear for good. Now try to guess the result of $this->addElement('static', null, 'Telefon:', '04556-8978765'); $this->addElement('static', null, 'Telefon:', '04556-8978765'); Right, it is not Telefon: 04556-8978765 Telefon: 04556-8978765 as expected, but rather Telefon: Telefon: 04556-8978765 Can anybody make any sense of this?

• Word wrap in multiline textbox after 35 characters

  - by Kanavi

  <asp:TextBox CssClass="txt" ID="TextBox1" runat="server" onkeyup="CountChars(this);" Rows="20" Columns="35" TextMode="MultiLine" Wrap="true"> </asp:TextBox> I need to implement word-wrapping in a multi-line textbox. I cannot allow users to write more then 35 chars a line. I am using the following code, which breaks at precisely the specified character on every line, cutting words in half. Can we fix this so that if there's not enough space left for a word on the current line, we move the whole word to the next line? function CountChars(ID) { var IntermediateText = ''; var FinalText = ''; var SubText = ''; var text = document.getElementById(ID.id).value; var lines = text.split("\n"); for (var i = 0; i < lines.length; i++) { IntermediateText = lines[i]; if (IntermediateText.length <= 50) { if (lines.length - 1 == i) FinalText += IntermediateText; else FinalText += IntermediateText + "\n"; } else { while (IntermediateText.length > 50) { SubText = IntermediateText.substring(0, 50); FinalText += SubText + "\n"; IntermediateText = IntermediateText.replace(SubText, ''); } if (IntermediateText != '') { if (lines.length - 1 == i) FinalText += IntermediateText; else FinalText += IntermediateText + "\n"; } } } document.getElementById(ID.id).value = FinalText; $('#' + ID.id).scrollTop($('#' + ID.id)[0].scrollHeight); } Edit - 1 I have to show total max 35 characters in line without specific word break and need to keep margin of two characters from the right. Again, the restriction should be for 35 characters but need space for total 37 (Just for the Visibility issue.)
