<p>Consider this is my aspx page content. I am going to populate the values for the TextBox only after the postback from server.

<p>I have the following jQuery:</p>

</code></pre>
<p>When <code>.child</code> is clicked I don't want the parent to hide but obviously because <code>.child</code> is a child of <code>.parent</code> this naturally happens. I've tried adding this:</p>
<pre><code>$('.child').click(function(e){
e.stopPropagation();
});
</code></pre>
<p>But it still doesn't work. I've also tried replacing <code>e.stopPropagation</code> with <code>return false;</code> </p>

<p>Now, what I want to make: if the user selects to see a patient's data, I want to give him the possibility to print the patient's record. I know how to print a file using java. But I don't know how to make such a file, how to form it. I mean it's not just printing "Hello world". It may need tables, colors, etc. How should I do this? Is there a way to make a prototype (ex. doc) file and then through the program fill just the data, or I have to fully form this file through my program? </p>

2,144,444 | 2,144,445 | related to Android audio driver | <p>While I was diving into the Android kernel. I had a question about audio device driver.</p>
<p>People say that...
- Android uses ALSA audio driver.
- HAL layer is C/C++ library
- ALSA driver runs in user space, not in kernel space</p>
<p>Then, questions:
1. What is the Audio Drivers(I guess it's ALSA driver) in the picture below?
ALSA driver should exist in the library portion, isn't it?
(http://developer.android.com/guide/basics/what-is-android.html)</p>
<p>2.
There should be nothing about audio driver in Android Kernel, if it conforms to the ALSA driver?</p>
<ol>
<li>
I have a wm8994.c codec source file which drives codec h/w actually.
who's going to call the functions in wm8994.c? I think ALSA HAL will. Am I wrong?</li>

<p>I've been coding for years but always on my own and I never share about how people structure their website before.</p>

<p>If the user types <em>http://mywebsite.com/folder/</em> it requests the index file of the requested folder which just contains the 'struct' file importation, for the other variable parts like the metadatas of webpages, I'm creating a folder named <em>meta</em> which contains a file for any type of data (.title, .description, .keywords) and of course the struct file is fetching the content of these informative file and display them in their appropriate place in the document.</p>
<p>I feel comfortable with that structure cause it's been a long time using it. But I'd really appreciate it if you were giving some advices or some useful links and/or tell me how you manage your own website.</p>

<p>As a programmer when you want to learn a programming language, you usually focus on syntax, language features, etc. </p>
<p>but knowing languages syntax in not important; the most important thing is the way of coding. simply the Programming Logic. obviously it is experimental and can't be formulated but some projects are similar in many aspects such as the class hierarchy, application layers, etc.</p>
<p>For example the Application layers a database application would have.</p>
<p>Or as another example to mention a more specific problem, which is the most common way to implement a multi-page application configuration wizard? designing individual forms, using inheritance, using control containers, etc. (I know it depends on the Application but there might be some similarities)</p>
<p>...anyway, what would you suggest to learn these things? books (I read many programming-how-to books but they're not enough to learn these things), open-source projects (in this case I'd prefer C#) or any other way you might think that is good.</p>

1,747,707 | 1,747,708 | better way to check if in array and then in array | <p>I am adding the following code to check whether a checkbox should be checked or not:</p>
<pre><code>is_array($current_color_id_array) ? in_array('1', $current_color_id_array) : ''
</code></pre>
<p>I'm just wondering if there is nicer/more concise way to do it perhaps?</p>
<p>Edit: Sorry I was not clear enough, and actually my code was wrong..</p>
<p>This is supposed to check if $current_color_id_array is an array because apparently if I don't check it will give me the error Warning: in_array() expects parameter 2 to be array</p>
<p>and it should also check if the value is in the array to mark the checkbox as checked. </p>
<p>this is all part of a checkbox function: </p>
<pre><code>function tep_draw_checkbox_field($name, $value = '', $checked = false, $compare = '') {
return tep_draw_selection_field($name, 'checkbox', $value, $checked, $compare);
}
</code></pre>
<p>it is the third parameter. So if I can reask this I would say is there a better way of writing: </p>
<pre><code>tep_draw_checkbox_field('color_id[]', '1', (is_array($current_color_id_array) && in_array('1', $current_color_id_array)))
</code></pre>
<p>and just in case, this is how the array is made:</p>
<pre><code>$color_id_query = tep_db_query("select color_id from " . TABLE_PRODUCTS_TO_COLORS . " where products_id = '" . (int)$product['products_id'] . "'");
while ($color_id_row = mysql_fetch_array ($color_id_query)) {
$current_color_id_array[] = $color_id_row['color_id'];
}

"Allow this precompiled site to be updatable" and "use fixed naming assemblies". In the Target location, I specify the folder name in my local machine. Once it is published successfully, I copy the contents from the local folder to the website folder in iis. Does this mean that I am precompiling the website. After copying the website, I don't see instant response to the pages. Initially it takes some time to load as if it is compiling at that time. After that, If I go to the same page again, it is fast. So, I don't think I am doing precompile but I am not sure. </p>
