  • C# Dictionary Performance

    - by derek
    I am using a Dictionary to store data, and will be caching it. I would like to avoid server memory issues, and have good performance by limiting the size of the Dictionary<, either in size or number of entries. What is the best method of doing this? Is there another class I should be considering other than a Dictionary?

I ideally want to do a switch statement, and return something based on the Type of the generic (string/int/long/etc). Is this possible?

  • How to make a scrollable widget?

    - by Sebi
    As far as I have read in the Internet and official documentation, it isn't possible to make a scrollable widget. Also all my tries failed. I even tried to subclass TextView to implement my own scroll method, but nothing worked. Are there any ways to achieve that? Btw.... there are solutions if you use for example htc sense or home desktop ++, but i want to make it available to other users which don't use this

  • Javascript click function for multiple Classes

    - by Jason Bassett
    So basically I have this little social networking site which allow comments. I've built a comment section that will slide down once a user clicks "Comment" and it slides down under the users status. My problem is that right now, the JavaScript only works on ONE post ID, and not the rest obviously seeing you can only use an ID once. But of course if I use classes instead, All the comment sections slide down because now they're all the same class. See below for my HTML and JavaScript. So if someone has a better method out there, please help :) $(function () { $(".comment-box").slideUp(); //when "comment" is clicked, slide down the comment box. if ($(".comment-box-btn").click(function () { $(".comment-box").slideDown(); })); //when "cancel" is clicked, slide up the comment box. if ($(".close-comment-box").click(function () { $(".comment-box").slideUp() })); }); And here's the HTML used //anchor for "Comment" <a class="comment-box-btn" href="#"><i class="icon-comment"></i> Comment</a> //comment box <div class="row comment-box" style="display:none;"> <div class="col-md-12"> <form accept-charset="UTF-8" action="" method="post"> <textarea class="form-control animated" cols="180" id="new-comment" name="comment" placeholder="Comment.." rows="1"></textarea> <div class="text-right" style="margin-top:20px;"> <a class="btn btn-default close-comment-box" href="#"> <span class="glyphicon glyphicon-remove"></span> Cancel</a> <button class="btn btn-info" type="submit">Comment</button> </div> </form> </div> </div>

  • Is it a bad programming practice to have "Public" members inside an "Internal" class?

    - by Amby
    I mean, won;t it be more specific and appropriate if i "only" keep "protected","internal" and "private" members (field,method,property,event) in a class which is declared as "internal" ? I have seen this practice ( having "public" members in an "internal" class) in various code so just wanted to know is it a bad practice or does it has some benefit or advantage. [Only concerned about C#] Thanks for your interest.

  • Android - what's the difference between the various methods to get a Context?

    - by Alnitak
    In various bits of Android code I've seen: public class MyActivity extends Activity { public void method() { mContext = this; // since Activity extends Context mContext = getApplicationContext(); mContext = getBaseContext(); } } However I can't find any decent explanation of which is preferable, and under what circumstances which should be used. Pointers to documentation on this, and guidance about what might break if the wrong one is chosen, would be much appreciated.
