• Find Line Above or Below in Javascript

  - by Dark Falcon

  I am working on an in-place HTML editor, concentrating on Firefox only right now. I have an element inserted where the cursor should be and also have left and right arrows working, but I can't seem to find a way to find: Start and end of a line for the home and end keys The next line up or down for the up/down arrows. I see document.elementFromPoint, but this doesn't get me a Range object. The Range object itself seems rather useless when it comes to using pixel positions.

• Automatically closing braces in emacs?

  - by Dave Rigby

  Hi I've seen a plugin for Vim called AutoClose (discovered from this post) which automatically adds the closing brace when typing '(', '{' etc. For example; when I type the following ( | is the cursor): int main(| I would like the closing ) to be inserted automatically for me: int main(|) Does anyone know of a similar feature for emacs - Google has failed me this time!

• Protocol error in TDS stream

  - by jasonline

  What are the possible causes of this type of error - "[Microsoft][ODBC SQL Server Driver]Protocol error in TDS stream"? And how can this be fixed? My application runs in C++ calling stored procedures implemented in SQL Server. There's this one SP (containing select and update statements) that causes this problem, after which all succeeding queries will return that the cursor is in an invalid state. I've checked the SP but I don't see any possible problem.

• Delphi - Why does ExplicitWidth and ExplicitHeight keep appearing in .DFM files and what is it!?

  - by Pauk

  We've noticed that when checking in updates that our .DFM files have had ExplicitWidth and ExplicitHeight properties added for what appears to be no particular reason. My two questions are, what are they for and why do they get automatically added by Delphi? Below is an example with the property in: object Splitter2: TcxSplitter Left = 0 Top = 292 Width = 566 Height = 8 Cursor = crVSplit HotZoneClassName = 'TcxXPTaskBarStyle' AlignSplitter = salBottom Control = BottomPanel Color = clBtnFace ExplicitWidth = 8 end

• How do I track the method the user is looking at in VS 2010 IDE as an Addin

  - by Rob

  I have been wandering around the object model for VS 2010 and haven't been able to work out the best method for watching what the user is looking at in the main edit window. I know that each Class/method/property is broken down into its own . What I would ideally like is to hook to an event which says "The user has moved the cursor onto Project.Class.Method" and ideally "and is looking at line 4". Any suggestions?

• jQuery: List expands on page load

  - by Hasanah

  I've been looking for something very simple: How to make a side navigation expand with animation on page load, but all the tutorial websites I usually go to don't seem to have it. The closest I could find is this jQuery sample: http://codeblitz.wordpress.com/2009/04/15/jquery-animated-collapsible-list/ I've managed to strip down the list like so: <script type="text/javascript" src="jquery-1.3.2.min.js"></script> <script type="text/javascript"> $(function(){ $('li') .css('pointer','default') .css('list-style','none'); $('li:has(ul)') .click(function(event){ if (this == event.target) { $(this).css('list-style', (!$(this).children().is(':hidden')) ? 'none' : 'none'); $(this).children().toggle('slow'); } return false; }) .css({cursor:'pointer', 'list-style':'none'}) .children().hide(); $('li:not(:has(ul))').css({cursor:'default', 'list-style':'none'}); }); <body> <fieldset> <legend>Collapsable List Demo</legend> <ul> <li>A - F</li> <li>G - M <ul> <li>George Kent Technology Centre</li> <li>Hampshire Park</li> <li>George Kent Technology Centre</li> <li>Hampshire Park</li> </ul> </li> <li> N - R </li> <li>S - Z</li> </ul> </fieldset> My question is: Is there any way to make this list expand on page load instead of on click? I also don't need it to collapse at all; basically I need only the animating expansion. Thank you for your time and advice. :)

• jQuery: Setting 'style' attribute of element with object

  - by JamesBrownIsDead

  I saw this in our codebase the other day: link.attr('style', map({ color: '#9a4d9e', cursor: 'default' })); map is defined as: function map(map) { var cssValue = []; for (var o in map) { cssValue.push(o + ':' + map[o] + ';') } return cssValue.join(';'); } Is map necessarily? Is there a shorter way to do this? It's important to note that the "style" attribute overrides any styles set by a class added/defined in the "class" attribute.

• What is your most productive shortcut with Vim?

  - by Olivier Pons

  I've heard a lot about Vim, both pros and cons. It really seems you should be (as a developer) faster with Vim than with any other editor. I'm using Vim to do some basic stuff and I'm at best 10 times less productive with Vim. The only two things you should care about when you talk about speed (you may not care enough about them, but you should) are: Using alternatively left and right hands is the fastest way to use the keyboard. Never touching the mouse is the second way to be as fast as possible. It takes ages for you to move your hand, grab the mouse, move it, and bring it back to the keyboard (and you often have to look at the keyboard to be sure you returned your hand properly to the right place) Here are two examples demonstrating why I'm far less productive with Vim. Copy/Cut & paste. I do it all the time. With all the classical editors you press Shift with the left hand, and you move the cursor with your right hand to select text. Then Ctrl+C copies, you move the cursor and Ctrl+V pastes. With Vim it's horrible: yy to copy one line (you almost never want the whole line!) [number xx]yy to copy xx lines into the buffer. But you never know exactly if you've selected what you wanted. I often have to do [number xx]dd then u to undo! Another example? Search & replace. In PSPad: Ctrl+f then type what you want you search for, then press Enter. In Vim: /, then type what you want to search for, then if there are some special characters put \ before each special character, then press Enter. And everything with Vim is like that: it seems I don't know how to handle it the right way. NB : I've already read the Vim cheat sheet :) My question is: What is the way you use Vim that makes you more productive than with a classical editor?

  Hi, I am using ui tabs a lot.In my last project i add an icon just before tabs and the tab links start a strange behavior, you can not click to change the tabs if you are above tab name BUT only when you are outside tab name. Here is the code <div style="float:left;display:inline;width:718px;padding:5px;border:1px solid #ececec"> <!--ICON just before TABs--> <div style="z-index:1;position:relative;top:30px;left:5px"> <img src="../graphics/icons/add.gif" onclick="AddTab();" href="javascript:void(0);" id="addNewTab"/> </div> <div id="tabs" > <ul > <li > <img src="../graphics/icons/x.gif" onclick="RemoveTab(this)" style="cursor: pointer;" /> <a href="#tab-1"><span id="tabContent-1"><span class="tabText" >TAB1</span></span></a> </li> <li > <img src="../graphics/icons/x.gif" onclick="RemoveTab(this)" style="cursor: pointer;" /> <a href="#tab-2"><span id="tabContent-2"><span class="tabText" >TAB2</span></span></a> </li> </ul> <div id="tab-1" > contents </div> <div id="tab-2" > contents </div> </div><!--tabs--> I know that ui.css has position relative for tabs .ui-tabs .ui-tabs-nav { list-style:none outside none; padding:0.2em 0.2em 0; position:relative; } and i dont know if meshing up with my icon. If i remove the position:relative from the icon (add.gif) everything works fine Any help is appreciated
