1,331,054 | 1,331,055 | Confused by Use of ~ in ASP.NET | <p>I am programming for the first time in ASP.NET. It's proven to be very easy and I'm really enjoying it. One feature I like is that, within a web page, I can reference files from root by using the tilde (~) character and then the rest of the path. However, this does not seem to be consistent. For example, it works within the context of href, e.g.</p>
<pre><code><link href="~/css/StyleSheet.css" />
</code></pre>
<p>It doesn't work with respect to src, e.g.</p>
<pre><code><img src="~/images/header.jpg" />

<p>Why is this? Is there something I'm doing wrong. The inconsistency is annoying.</p>

1,930,416 | 1,930,417 | Change the Color of Highlighted text in Android | <p>I'm not sure that this is possible, perhaps someone can set me straight. I have an EditText View in an android application that has white text on a blue background. When the text is selected (via a long press and the edit dialog), I'd like have the highlight be white and change the text color to be black. Annoyingly though there does not seem to be a way to set the color of the text on highlight. You can set the highlight color using <em>textColorHighlight</em>, but not the text color, so setting a white highlight with white text results in a big white block.</p>
<p>It seems like it should be something trivial you can do declaratively in the xml, but though I've tried many combinations of styles and colors, I've not been able to change the color. </p>
<p>Checking other standard applications it seems that the text color never seems to change so I'm thinking this is something that's not easily done. I'd rather not have to subclass the EditText if at all possible just to something so simple. Am I missing something? Can this be done in the view xml?</p>

<p>Recently I had to store a very amount of data within a collection and thought of using a dictionary for it's the fastest collection to get an object by index. But my collection would have to allow duplicated keys. But in fact duplicated keys would not be a problem since any of the object returned would be meet the requirements (The objects are not exactly unique, but the keys would be).</p>
<p>Some more research led me to the following post:</p>
<p><a href="http://stackoverflow.com/questions/4598826/c-sharp-hashset-contains-non-unique-objects">C# Hashset Contains Non-Unique Objects</a></p>

Additionally, Firebug is showing one (random?) image as loading until the php script is completely finished running. I can view the script in <code>top</code> and it is running as a separate process. How can I get the browser to stop waiting for it to finish though?</p>

I try to localize the PHP interpreter (in Debian, that would be /usr/bin/php for example) but I don't find it. <code>which</code> is not installed and since I'm not root I cannot install rpm packages. I know php is installed because I can type php in terminal and it goes in read mode. I tried <code>find / -type d -name php</code> or f<code>ind / -type f -name ph</code>p and I got the output "terminated" which I guess means nothing was found. How could I locate php?</p>

614,569 | 614,570 | What is the best update mechanism for a software cataloguing application? | <p>I'm developing an Android application very much like the the Android Market (now Google Play) in which I offer various softwares to user for installation. The difference is here that I want the user to be able to browse the applications even when there is no internet connectivity. That means I have to store the data on a local database (here I want to use sqlite) and this data needs to be updated periodically.<br>
Now my question is this. How should I implement this update mechanism to have the best performance and availability?<br>
I think I have a few options which is as following:</p>
<ol>
<li>To update the whole database every time. This way I have to download every single record every time to have the updated content.</li>
<li>To update the data based on the date they were added. Although this seems a good way, but there is a possibility that the previously added content may be edited and they are omitted in this approach. Also there is this possibility that some of the items are deleted.</li>
</ol>
<p>These were what I thought I can do but I don't know which is best way to go on?! Also I am open to any other suggestion that might work here.</p>

4,345,667 | 4,345,668 | Python: Check an index against multiple other indexes | <p>I am using Python and I would like to check the location of a value in a list of lists against other indexes.</p>
<p>Like if I had 1 at (1, 1) I would want to be able to check if 1 were at the other indexes so I could make something happen based on which index it matched. </p>
<p>For example:</p>
<pre><code>list_of_lists = [
[4, 5, 6],
[7, 1, 8],
[6, 2, 9]
]
if 1 in row for row in list_of_lists:
if index of 1 is (0, 0), (0, 1), or (0, 2)
print ("It is in the First row!")
if index of 1 is (1, 0), (1, 1), or (1, 2)
print ("It is in the second row!")
</code></pre>
<p>If this worked correctly it should print: "It is in the second row!" Because the index of 1 matches with one of the indices in the third if statement. They may not necessarily be rows in some instances where I would be using this. So If you could provide a way that would not use the rows in your answer. Just a way to look at indexes and compare them. Obviously this is not the correct syntax. But how would I do that in Python? How would I get the index of 1 and compare it to other indexes in a list of lists?</p>

3,863,234 | 3,863,235 | possible to extract functions from a javascript file? | <p>Not sure if this is the right approach of if this even a "good" question, but I'm loading a javscript as part of a plugin style architecture and I have the following problem:</p>
<p>If a particular node has a reference to a plugin, I want to load that plugin per the url provided via the json description of that plugin. the description will have something like the following (or a functional equivalent):</p>
<pre><code>{
"pluginSrc" : "http://mysite.com/plugins/1204.js",
"configData" :
{
"someData", "someValue",
"someMoreData", "etc"
}
}
</code></pre>
<p>When the javascript loads, I'll have an onload handler that will check to see if a function name exists on the window object and if so, create a new instance of that function and pass it the config data (more or less), this part works very well, with a few exceptions.</p>
<p>Sometimes I do not have a reference to the name of the function that I need to invoke and there is no way to get it from the json. What would be ideal, is if I could tell which function was added to the window object on the script's onload callback and create an instance of that function. Is this possible? I only need to worry about modern browsers, particularly webkit. Apologies if the question isn't clear, I'd be happy to clarify, but producing a fiddle might be difficult as there's a lot of code to write to reach a minimal example.</p>
<p>What I'm thinking about so far is to create some kind of global variable in the loaded script file like</p>
<pre><code>function MediaAnalytics(){};
var LoadedClass = MediaAnalytics;
</code></pre>
<p>and just creating an instance of LoadedClass when the script is loaded, but this falls short of a panacea because I will not always be writing the plugin.</p>
<p>EDIT: These scripts will most likely not be from the same domain.</p>

2,080,017 | 2,080,018 | Help - use PHP-broswer, or proxy or get_page_contents or include page, or something else? | <p>I am trying to develop a web application for which I need to capture a specific user-driven event (such as mouse dblclick) occurring on a different-website page loaded through my website.</p>
<p>What I want to do is :</p>
<ol>
<li>User visits my website - hosted by me.</li>
<li>There, user types in any website URL (e.g.: <a href="http://www.example.com" rel="nofollow">http://www.example.com</a>)</li>
<li>That URL page gets loaded as is. </li>
<li>When user double-clicks mouse over any link or image from that page, a popup/side-panel is displayed with content related to that particular image or link.</li>
</ol>
<p>I can do this with a combination of PHP get_page_contents or include-page, and javascript dblclick.
However, when user clicks on any link or submits a form, the control goes to that other website, where I cannot show the side-panel.
I might be able to handle the links by proxifying them when user clicks on any of them. How do I handle forms submission and other stuff ?
I can use a full-featured proxy, but that will be too heavy just for the purpose of capturing the event.</p>
<p>My question is that is there a way to write some kind of light PHP script that sits on my website - that loads other websites contents as is, but lets me capture the mouse-dblclick event to show related-content in the side panel .</p>
<p>I have already searched the internet, but could not find anything.</p>
<p>Any help is really appreciated. Thanks.</p>
