  • Have you actually convinced anybody to Scala?

    - by Lukasz Lew
    I had limited success myself. I was able to hype a few persons about Scala. But in fact none of them made a meaningful effort to try to switch (usually from Java). I would like to read both success and failure stories here. Both long tries and short ones. My goal is to find ways of presenting Scala to another person, friend, co-worker (not an audience) that will make them want to use this great language.

  • Is it bad practice to 'mix class and interfaces in the same package'?

    - by DerMike
    Hello, I just found something that I never heard of before and I do not agree with (by now). In an (upvoted and not further commented) answer I read "why to mix class and interfaces in the same package" So I wonder, if there are reasons to separate Interfaces and implementations in Java. I know that we are not obliged to have all implementations in the package of the interface, but is it (sometimes) wise to have none there? Regards Mike [;-)

  • Default subclass objects in Sqlalchemy?

    - by Timmy

  • Set Controls with arbitrary positions on CTabItem

    - by Daziplqa

  • How do I upload a file when I know the client's filepath?

    - by GJTorikian
    I'm interested in the way Sonic Living detects your iTunes library XML file. It prompts the user to approve its actions, then automatically uploads the XML file based on the client OS (and assuming the default installation path of iTunes). How the heck does it do that? None of the upload libraries I've looked at have this feature. They all assume that a user will click "Select file..." then browse around for the right thing to upload.

  • How do I set a resource file to non-embedded

    - by themaninthesuitcase
    In Visual studio 2008 is it possible to have a resource file that is included as a separate file after compilation rather than as an embedded resource. This is to enable small changes to be rolled out more easily. I have tried build options of Resource, None, Compile and also copy local on and off for most of these. However when ever I try access the resource at run time I get a cannot find resource exception. Is this actually possible or am I wasting my time?

    Hi all, I have a table which is looped in <li>. On mouseover each row, there will be a border shown, and the row id="resFunc" will be displayed. However, in IE, the animation jumps up and down. Anyone has similar experience or solution to solve this? Thanks in advance! <div id="resDetails" align="left"> <table width="400px" class="resBox"> <tr> <td><b>{creator}</b></td> </tr> <tr> <td colspan="2"><div class="edit{_id}" id="{_id}"> {title}</div></td> </tr> <tr style="display:none" class="url{_id}"> <td colspan="2" class="edit_url{_id}" id="{_id}">{url}</td> </tr> <tr> <td colspan="2" class="edit_area{_id}" id="{_id}">{description}</td> </tr> <tr id="resFunc{_id}" style="display:none"> <td colspan="2" align="right"><b><a href="#" id="{_id}" class="editRes">Edit</a>&nbsp;&nbsp; <a href="#" class="deleteResource" id="{_id}">Delete</a></b> </td> </tr> </table><br> </div> This is the onClick function :- $(".resBox").mouseover(function(){ var id = $(this).attr("id"); $(this).addClass('highlight'); $('#resFunc'+id).show(); }); $(".resBox").mouseout(function(){ var id = $(this).attr("id"); $(this).removeClass('highlight'); $('#resFunc'+id).hide(); });

  • I need to change a zip code into a series of dots and dashes (a barcode), but I can't figure out how

    - by Maggie
    Here's what I've got so far: def encodeFive(zip): zero = "||:::" one = ":::||" two = "::|:|" three = "::||:" four = ":|::|" five = ":|:|:" six = ":||::" seven = "|:::|" eight = "|::|:" nine = "|:|::" codeList = [zero,one,two,three,four,five,six,seven,eight,nine] allCodes = zero+one+two+three+four+five+six+seven+eight+nine code = "" digits = str(zip) for i in digits: code = code + i return code With this I'll get the original zip code in a string, but none of the numbers are encoded into the barcode. I've figured out how to encode one number, but it wont work the same way with five numbers.

  • Display "custom" view (various images, various text). Should I use UIWebView?

    - by aw
    First: No, none of the content should be loaded from the web. All content parts are shipped with the main bundle. I have n images and mass of text (including lists). Instead of building all view parts programmatically in objective-c if was thinking of using an UIWebView and build "only" the HTML dynamically. Does anything speaks against it? How does UIWebView work with local content? Links and resources welcome. Thanks

  • ie8 playing funny with list-style-position: inside

    - by LeeR
    Ok, So problem here... when using list-style-position:inside in IE8 the first like is indented but every line after that is not. So the new lines appear under the bullet. This is fine, but when I use a list with that css applied with an a tag within the li then the text automatically gets pushed to the second line, and the first line is empty. When I remove the a tag from the li then it jumps back up. Any idea on why this might be or is this a bug in the ie8 world or do I just need to double check my css? Any insights would be much appreciated. As asked here is some code <div id="sub_nav"> <ul> ... <li><a class="active_page" href="#">Liposculpture</a> <ul> <li><a href="#">What is Liposculpture?</a></li> <li><a href="#">About Liposculpture surgery</a></li> <li><a href="#" class="active_sub">After Liposculpture surgery</a></li> <li><a href="#">Post Op Instructions</a></li> <li><a href="#">Liposculpture Side Effects</a></li> <li><a href="#">Liposuction Introduction to</a></li> <li><a href="#">Tumescent Liposculpture</a></li> </ul> </li> ... </ul> </div> For the CSS I will try and show it best I can #sub_nav li { width: 200px; padding:4px 0; border-bottom: 1px #CCC solid; } #sub_nav li a { text-decoration: none; color:#555; padding:7px 15px 7px 15px; display: block; } #sub_nav li ul li { list-style-position: inside; list-style-type: disc; font: 11px Arial; padding-left:15px; color:#FFF; border-bottom: none; } #sub_nav li ul li a { padding:0; margin:0; text-indent: 0; } Hope this helps

  • Minor tweak to this javascript function?

    - by RKS
    I have a script that shows/hides used via onClick. I can get it to show/hide just fine, but I can't get it to show/'hide everything else'. So what I get is a bunch of open containers when I really want just the one. Javascript: <script> function showfields(fields){ if(document.getElementById(fields).style.display=='none'){ document.getElementById(fields).style.display='block'; } else{ document.getElementById(fields).style.display = 'none'; } } </script> HTML: <div id="hidden" class="steps" style="display: block;"> <div class="section" style="margin-right: 10px;"> <h2>Something</h2> </div> <button class="continue dropdown" id="showLink" onClick="showfields('hidden2');return false;" href="#">Continue</button> </div> <div id="hidden2" class="steps" style="display: block;"> <div class="section" style="margin-right: 10px;"> <h2>Something2</h2> </div> <button class="continue dropdown" id="showLink" onClick="showfields('hidden3');return false;" href="#">Continue</button> </div> <div id="hidden3" class="steps" style="display: block;"> <div class="section" style="margin-right: 10px;"> <h2>Something3</h2> </div> <button class="continue dropdown" id="showLink" onClick="showfields('hidden3');return false;" href="#">Continue</button> </div> <div id="hidden4" class="steps" style="display: block;"> <div class="section" style="margin-right: 10px;"> <h2>Something4</h2> </div> <button class="continue dropdown" id="showLink" onClick="showfields('hidden4');return false;" href="#">Continue</button> </div> Thanks

  • Should enumerators be placed in a separate file or within another class?

    - by Icono123
    I currently have a class file with the following enumerator: using System; namespace Helper { public enum ProcessType { Word = 0, Adobe = 1, } } Or should I include the enumerator in the class where it's being used? I noticed Microsoft creates a new class file for DockStyle: using System; using System.ComponentModel; using System.Drawing.Design; namespace System.Windows.Forms { public enum DockStyle { None = 0, Top = 1, Bottom = 2, Left = 3, Right = 4,. Fill = 5, } }
