720,515 | 720,516 | hiding a div when the mouse is a certain distance away from that div | <p>I have a div on a page which is toggled by an item in a navigation bar. What I'd like to do is have that div hide when the user's mouse gets a certain distance away from the div's outer boundry.</p>
<p>Here's some example code:</p>
<pre><code><ul>
<li>This is link A</li>
<li>This is link C</li>
<li id="trigger">This is link D</li>
</ul>
<div id="megaMenu">This is where the menu content goes</div>
</code></pre>
<p>So, when the user mouses over the li#trigger, the mega menu slides down. What I'd like to do is have the #megaMenu slide up when the user's mouse is 50px outside the bounds of the div. Any suggestions?? </p>
<p>Here's the core jQuery I was using:</p>
<pre><code>$(document).ready(function(){
$('li#locations a').hover(function(){
$('#locationsSuperNav').slideDown();
});
$('.superNavClose').hover(function(){
$('#locationsSuperNav').slideUp('fast').removeClass("open");
});
});
</code></pre>
<p>The second piece of the code (.superNavClose) was an attempt at putting a hot spot around the menu to close it when the user's mouse hits it. There are a bunch of links inside the mega menu so I need to keep it open while the user is working with it. I was thinking that closing the div when the mouse is a certain distance away would work pretty good. Thanks in advance for any suggestions!</p>

5,060,085 | 5,060,086 | Function that takes a string as input and counts the number of times the vowel occurs in the string | <p>So I am very new to python and am in the process of learning the basics. I am trying to create a function the counts the number of vowels in a string and returns how many times each vowel occurs in the string. For example if I gave it this input, this is what it would print out.</p>
<pre><code> >>>countVowels('Le Tour de France')
a, e, i, o, and u appear, respectively, 1,3,0,1,1 times.
</code></pre>
<p>I made this helper function to use, but then I'm not exactly sure how to use it.</p>
<pre><code>def find_vowels(sentence):
count = 0
vowels = "aeiuoAEIOU"
for letter in sentence:
if letter in vowels:
count += 1
print count
</code></pre>
<p>And then I thought that maybe I could use formatting to get them in the write places, but I am not sure the notation that would be used for example, one of the lines for the function could be: </p>
<pre><code> 'a, , i, o, and u appear, respectively, {(count1)}, {(count2)}, {(count3)}, {(count4)}, {(count5)} times'
</code></pre>
<p>I am not sure how I would be able to fit the above in the function.</p>

I am doing something a bit different, the user can configure its connection to facebook from a custom preference. I was successfull when doing it for twitter and foursquare. However, the method Facebook.authorize requires an Activity as parameter, and since i am inside a preference, i am not able to find any reference to an activity object.</p>
<p>So my question here is, how to get a reference for an activity inside a preference?</p>
<p>Thank you all

1,393,633 | 1,393,634 | Sorting files with the same first 3 letters, than deleting the older files? | <p>I had a question last week, and you quickly alleviated any concern that it would roadblock me, hoping that you can help a beginner program once more!</p>
<p>I'm trying to automate one of my daily mundane tasks and it's being quite a bugger, I think mainly because I'm not taking the correct approach.</p>
<p>Each morning I go through a system directory that houses many files with the same prefix, and a generated number following it. I have to sort alphabetically first, then remove the oldest versions of that file.</p>
<p>Here's an example pic of my directory: <a href="http://i.imgur.com/5l2Am.png" rel="nofollow">http://i.imgur.com/5l2Am.png</a></p>
<p>I was going to approach this situation by just sorting the files by name and comparing the first 3 letters to the following file, and if they were identical I would delete (or move to a backup folder) the second file, until they didn't match any longer, and I would move onto the next prefix as the comparator.</p>
<p>The problem with this though I found, is that they aren't always sorted correctly, and I risk deleting the wrong files.</p>
<p>Has anyone had experience with something of this nature? In my head and on VS I can put the pieces all there, but just can't seem to link it together, mainly because I've never ventured into the system.IO class before, but I want to learn!</p>
<p>Any advice is appreciated, and if you want to see my futile attempts I'll gladly share them :P.</p>
<p>Thanks,
Nick</p>

2,597,432 | 2,597,433 | Center a formatted row of integers in Python? | <p>I am a bit new to Python, having dabbled in VB.NET, C, and a few other odd languages, so I am finding the approaches used before don't always apply to Python. In this case, I want to print out a series of integer values into columns and center them in as small amount of code as possible.</p>
<p>With plain strings, this is easy as:</p>
<pre><code>print "%s|%s|%s|%s" \
% (s1.center(w), s2.center(x), s3.center(y), s4.center(z))
</code></pre>
<p>Where <code>w</code> through <code>z</code> is some integer value specifying the width of the field that the strings, <code>s1</code> through <code>s4</code>, should be center in.</p>
<p><br />Doing the same with numbers when I want to use format specifiers like <code>%0.2x</code> or <code>%4d</code> won't work because integers don't have a <code>center</code> function.</p>
<p>Using a more C-oriented approach, I could convert each integer independently:</p>
<pre><code>s1 = str("%0.4x" % (i)).center(w)
s2 = str("%0.2x" % (i)).center(x)
s3 = str("%0.2x" % (i)).center(y)
s4 = str("%0.8x" % (i)).center(z)
print "%s|%s|%s|%s" % (s1, s2, s3, s4)
</code></pre>
<p><br />But that seems to be "unpythonic", if I am picking up the lingo correctly. What would be a good "pythonic" way to do this? It needs to be something that works with Python 2.4 and 2.7 (I am working in both environments).</p>
<p>Thanks!</p>

2,039,426 | 2,039,427 | GridView Inital Editing mode? | <p>I am writing a web application that is used for tracking and entering some everyday user data... Every day I need to enter some data for multiple users manually...</p>
<p>I will choose the date with the calendar, and for that date I will get DB values assigned for all users on chosen date...If there are some entries in database for that date i will display it in gridview...</p>
<p>Here is the look of gridview for chosen date...</p>
<pre>
USERS DATA
------------
User1 Data1
User2 Data2
User3 Data3
</pre>
<p>But, if I choose the date for which there are no entries in DB, I would like to display the gridview containg User names in each row, but I want the second column (DATA field) to be initially editable for ALL rows (the whole second column should contain textboxes for inserting values, not only selected row as in standard editable gridview mode) allowing inserting of wanted values...</p>
<p>I want it to look something like this</p>
<pre>
USERS DATA
----------------
User1 TextBox
User2 TextBox
User3 TextBox
</pre>
<p>My idea is to get Users list from DB and create a datatable with first column containg returned user names, and second column empty... This datatable will be datasource for gridview in which I am going to disable editing mode, and in normal (displaying) mode I am going to have TemplateField containg of textboxes bound to that datatable in second column, and labels displaying usernames in first column... When entering all values there will be SAVE button who is calling a method that will read entered values from datatable and save it to database... </p>
<p>Is there a better way to implement this functionality? If Templatefield textboxes are bound to datatable (as gridview datasource) textboxes entered values are going to be accessible from datable object, but Save button click causes postback, and I don't know how to preserve datatable state? Is there a better way to get wanted gridview with whole second column availibe for inserting new values?</p>

<p>EDIT!!</p>
<p>Second attempt was to use <a href="http://developer.android.com/reference/android/view/ViewTreeObserver.OnPreDrawListener.html" rel="nofollow">http://developer.android.com/reference/android/view/ViewTreeObserver.OnPreDrawListener.html</a> instead of <a href="http://developer.android.com/reference/android/view/ViewTreeObserver.OnGlobalLayoutListener.html" rel="nofollow">http://developer.android.com/reference/android/view/ViewTreeObserver.OnGlobalLayoutListener.html</a>
In <code>OnPreDrawListener</code> we can read that <code>At this point, all views in the tree have been measured and given a frame. Clients can use this to adjust their scroll bounds or even to request a new layout before drawing occurs.</code> so basically at this point we should adjust scrolling. So I created:</p>
<pre><code>@Override
public boolean onPreDraw() {
if (hsv.getChildCount() > 0 && hsv.getChildAt(0).getWidth() > mScreenWidth) {
hsv.scrollTo(100, 0);
return false;
}
return true;
}
