4,040,040 | 4,040,041 | Is it possible to sort two lists(which reference each other) in the exact same way? | <p>Okay, this may not be the smartest idea but I was a bit curious if this is possible. Say I have two lists:</p>
<pre><code>list1 = [3,2,4,1, 1]
list2 = [three, two, four, one, one2]
</code></pre>
<p>If I run <code>list1.sort()</code>, it'll sort it to <code>[1,1,2,3,4]</code> but is there a way to get to keep list2 in sync as well(so I can say item 4 belongs to 'three')? My problem is I have a pretty complex program that is working fine with lists but I sort of need to start referencing some data. I know this is a perfect situation for dictionaries but I'm trying to avoid dictionaries in my processing because I do need to sort the key values(if I must use dictionaries I know how to use them).</p>
<p>Basically the nature of this program is, the data comes in a random order(like above), I need to sort it, process it and then send out the results(order doesn't matter but users need to know which result belongs to which key). I thought about putting it in a dictionary first, then sorting list one but I would have no way of differentiating of items in the with the same value if order is not maintained(it may have an impact when communicating the results to users). So ideally, once I get the lists I would rather figure out a way to sort both lists together. Is this possible?</p>

4,908,166 | 4,908,167 | JavaScript: Return owner method from inside onclick function | <p>I am currently writing a custom dialog box script in JavaScript (to show dialog boxes with a choice of buttons, titles, etc.) thus mimicking C#'s MessageBox.Show() method. However, I'm having problems with correctly returning values from the function.</p>
<p>For example, the Show() method I have created is static, and called as follows from a button click:</p>
<pre><code><input type="button" onclick="return MessageBox.Show(dialogueMessage, 'Really Delete?', 'confirm', false)") />
</code></pre>
<p>Once the MethodBox.Show() function has been called, the dialog is displayed. I would like the option so that when a user clicks on the "Yes" button, the MessageBox.Show() function returns true, otherwise it returns false. The code I have for creating the (dynamic) buttons is as follows:</p>
<pre><code>var yesButton = document.createElement('input');
yesButton.setAttribute('type', 'button');
yesButton.setAttribute('value', 'Yes');
yesButton.setAttribute('name', 'button-yes');
yesButton.onclick = function() { MessageBox.Hide(); return true; };
var noButton = document.createElement('input');
noButton.setAttribute('type', 'button');
noButton.setAttribute('value', 'No');
noButton.setAttribute('name', 'button-no');
noButton.onclick = function() { MessageBox.Hide(); return false; };
</code></pre>
<p>However, as you can appreciate, the 'return false' / 'return true' statements refer to the button itself, and not the function (MessageBox.Show()). What I would like to know, is if there's a method I can use return the function when (and only when) the user clicks one of the buttons, so that the button clicked to call the function can be correctly used.</p>
<p>It's difficult for me to explain what I'm trying to achieve, but the above should make sense.</p>
<p>Thanks,
Ben.</p>

<a href="http://stackoverflow.com/questions/1132941/least-astonishment-in-python-the-mutable-default-argument">“Least Astonishment” in Python: The Mutable Default Argument</a> </p>
</blockquote>
<p>I was writing some code this afternoon, and stumbled across a bug in my code. I noticed that the default values for one of my newly created objects was carrying over from another object! For example:</p>
<pre><code>class One(object):
def __init__(self, my_list=[]):
self.my_list = my_list
one1 = One()
print(one1.my_list)
[] # empty list, what you'd expect.
one1.my_list.append('hi')
print(one1.my_list)
['hi'] # list with the new value in it, what you'd expect.
one2 = One()
print(one2.my_list)
['hi'] # Hey! It saved the variable from the other One!
</code></pre>
<p>So I know it can be solved by doing this:</p>
<pre><code>class One(object):
def __init__(self, my_list=None):
self.my_list = my_list if my_list is not None else []
</code></pre>
<p>What I would like to know is... Why? Why are Python classes structured so that the default values are saved across instances of the class?</p>
<p>Thanks in advance!</p>

2,263,857 | 2,263,858 | Is document.location.protocol ever invalid? | <p>I want to construct URLs with the same scheme (presumably, "http:" or "https:") as the page that loaded the currently-running JavaScript. Modern browsers support simply omitting the scheme (for example, <code>src="//example.com/test.js"</code>), but this isn't fully cross-browser compatible. (I've read that IE 6 is the only browser that doesn't support it, but I still need compatibility with that version.)</p>
<p>The cross-browser way to do this seems to be to check <code>document.location.protocol</code>. For example, Google Analytics uses:</p>
<pre><code>('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + ...
</code></pre>
<p>In Google's case, they wanted to use different domains depending on whether the request uses SSL, so that pattern makes sense. But I've seen others use the same pattern when only the scheme is changing:</p>
<pre><code>('https:' == document.location.protocol ? 'https:' : 'http:') + "//example.com"
</code></pre>
<p>(One example is in the "Final Wufoo Snippet" at <a href="http://css-tricks.com/thinking-async/" rel="nofollow">http://css-tricks.com/thinking-async/</a>.)</p>
<p>I'd prefer to use this simpler expression instead:</p>
<pre><code>document.location.protocol + "//example.com"
</code></pre>
<p>Should I really be concerned about the possibility of <code>document.location.protocol</code> taking on some value other than "https:" or "http:" when my code is used on sites I don't control?</p>

Each of those queries and is different and when those files are run separately, the query is made and the data got is converted into an excel file and is downloaded. Now using th code snippet above, i intend to loop through the files such that each query is made and converted to excel file which is downloaded on the fly. But instead, its only the first file in the code snippet thats executed and the other file doesnt get excuted. What could be causing this and how can i solve the problem i have at hand which is: i would like to be able to have one php file say export_all.php which calls specified php files such that instead of calling all of them separately, they are called by this one file .</p>

It’s Net_4.msi. But after I installed it, I cannot find IEnumerator code file.
I just wonder why Net_4.msi does not include all of .Net class.</p>
<p>Thanks.</p>
<hr>
<p>Update:
Thanks for replies and sorry for the confusions. </p>
<p>I am not asking for the definition of IEnumerator.
I think that “Net_4.msi” should include all of .Net classes/ interfaces’ source code files.
Such as in the folder </p>
<p>Net_4\Source\ndp\clr\src\BCL\System\Collections, </p>
<p>you may find IList.cs, ICollection.cs, IDictionary.cs and IEnumerable.cs.
These 4 files are IList, ICollection, IDictionary and IEnumerable source code files respectively.
Pls see picture: <a href="http://i55.tinypic.com/35clth4.jpg" rel="nofollow">enter link description here</a></p>
<p>But I cannot find the file: IEnumerator.cs. I just curious to know where IEnumerator.cs is. Why does IEnumerator.cs not include in the “Net_4.msi”?</p>
<p>Thanks.</p>

408,290 | 408,291 | How to pick contacts only from google contacts (not facebook etc) with phone numbers? | <p>I need to fix a bug in an old app of mine. Part of the bug is how I select contacts. Here is what I need:</p>
<ol>
<li>The contact must be from the
'normal' google contacts list, i.e.
I don't want to get any contacts
from facebook or similar.</li>
<li>The contact must have at least one phone number.</li>
<li>The contact must be from the old <code>android.provider.Contacts</code> provider.</li>
<li>If I can use an Intent to fetch the contact URI without having to create the selection list etc myself, then that is a bonus.</li>
</ol>
<p>Sounds simple, but I am really struggling. This is what I am trying:</p>
<pre><code>@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = new Intent(Intent.ACTION_PICK, Contacts.People.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT_REQUEST);
}
</code></pre>
<p>That works OK. I still see contacts without phone numbers, but I can live with that. Worse though is that I still see facebook contacts in the list! This seems to be in contradiction to the following quote found at the <a href="http://developer.android.com/reference/android/provider/Contacts.html">Froyo API for the deprecated Contacts content provider</a>:</p>
<blockquote>
<p>The APIs have been superseded by ContactsContract. The newer APIs allow access multiple accounts and support aggregation of similar contacts. These APIs continue to work but will only return data for the first Google account created, which matches the original behavior. </p>
</blockquote>
<p>That sounds like exactly what I wanted, but alas, not what I got. </p>
<p>Finally, here are my concrete questions that I hope someone can answer:</p>
<ol>
<li>Why am I seeing Facebook contacts when using the android.provider.Contacts content provider?</li>
<li>If this doesn't work, how else can I get the user to select a google contact with a phone number?</li>
</ol>
<p>Many thanks.

<p>The procedure for this is to set the style.top of DIV2 to be the same as DIV1, this should in theory position it on top of it. However so far attempts have failed.</p>
<p>The absolute positioning is working correctly, because putting in values moves it correctly, but I think I am using the wrong way to get the height/top values of DIV1.</p>

<p>I tried this:</p>
<p>divLoading.style.top = divContent.style.top;</p>

<p>Edit: The problem isn't how absolute/relative works but which javascript values are the correct ones to use. Using DIV2.style.top = DIV2.style.top - DIV1.clientHeight moves it to the top... but clientHeight is not correct, because if DIV1 changes size, it moves DIV2 way too far upwards.</p>
<p>Edit: offsetTop seems to be zero.</p>
