<p>The problem is that if a user enters some text, then clicks or tabs to another textbox, the OnTextChanged of the current textbox event fires fine but the textbox that the user clicked on does not keep focus. This causes problems because the user thinks they are on the next textbox but they aren't. And no object seems to have the focus.</p>

4,721,282 | 4,721,283 | What is a better practice to handle dynamic form content? | <p>I design a form that contains dynamic contents.</p>
<p>For example,
The form has a textfield for Paper_Name and a textfield for Paper_Link.
The user can add up to ten paper names and paper links.</p>
<p>The id for each paper name and paper link is as follows:</p>
<p>papername01, paperlink01, ..., papername10, paperlink10.</p>
<p>Those ids are dynamically created by JavaScript. In other words, if the user doesn't click Add Paper button and submit the form, the only field that will be received by the server is paperlink01, and papername01.</p>
<p>Now, the question what is a better practice to design the server PHP script to handle those submitted form content.</p>
<p>1> Use aJax form plugin?
2> Use regular form submission and iterate through all variables and see whether any of them is set?
3> use JSON data format?</p>
<p>Yes, the question is related to both server and client. I would like to know the best practice and change my client accordingly.
Please help and thank you</p>
<p>The form design looks like the following:
< div id="divDummy001">
< div id="paperTitle001Fld">
< label for="papertitle001">Title of Paper 001< /label >
< div>
< input type="text" size="16" value="" id="papertitle001" name="papertitle001" />
< /div >
< /div ></p>
<pre><code> < div id="paperURL001Fld" >
< label for="paperurl001">Paper Link 001< /label >
< div>
< input type="text" size="96" value="" id="paperurl001" name="paperurl001" />
< /div >
< /div >
< /div >

</code></pre>
<p>This is fine. But when it comes to rendering, I could add a virtual <code>render</code> method to the <code>Animal</code> base class just like the <code>eat</code> method.</p>
<p>But then animals source files have dependencies to the particular library that is being used. This doesn't make things modulable and maintainable. Plus, their rendering code basically doesn't concern them.</p>
<p>What is a nice way of putting the render specific code out of the derived classes ? </p>
<p>When I say nice, I mean without using something like an overloaded method that returns a different number for each derived class so I can do a big <em>if...else if ...</em>.</p>

228,344 | 228,345 | Function that takes a list of multiple strings and tuples | <p>So, I want to create a function that takes a list of multiple strings and tuples, and what it does is, if its a string, it just prints the string, but if its a tuple, the tuple takes an integer and a string and it multiplies them.</p>
<p>Example:</p>
<pre><code>print(something(["1stString", "2ndString", (3, "Pie"), (4, "Soda")]))
</code></pre>
<p>and it prints:</p>
<pre><code>1stString
2ndString
Pie
Pie
Pie
Soda
Soda
Soda
Soda
</code></pre>
<p>My miserable attempt:</p>
<pre><code>def something(s):
for x in s:
if isinstance(s, str):
print(s)
if isinstance(s, tuple):
x = tuple[0] * tuple[1]
print(x)
exit()

<p>This works for the strings but not for the tuples.</p>
<p>It prints out:</p>

2ndString
(3, 'Pie')
(4, 'Soda')
</code></pre>
<p>What am I doing wrong?</p>

How about if I want it to print it out as a list?</p>

<p>The compiler underlines the two results of the ternary operator inside the for loop, saying that IEnumerable<...> doesn't have a method overload called ThenBy (and similarly for ThenByDescending), but the sortQ will be an IOrderedEnumerable<...> in that block. Why isn't C# type inference picking that up?</p>
<p><strong>Update</strong>: for those who might have been confused before, what I left out of the original snippet was that I was assigning sortQ to the result of another query which forced the type inference engine to type sortQ as an IEnumerable<..>, which of course is what was screwing up my example. The answer below is the way around this. Thanks to @Marc for reading between the lines.</p>

The library has an option to either specify the manifest resource name for the file it needs or else specify a file path.</p>
<p>Up until now, I've just passed the file path string from the main appdomain where my program is to the sandboxed library appdomain. However, I want to move to using embedded resources instead so I don't have to make sure to include all these files and send them to their proper directories in the installer project.</p>
<p>Of course, the library is looking in the assembly that's running it (the sandbox appdomain) for the embedded resources. I need to know if there's a way to add resources to the mainfestResourceStream at runtime. If there is, I could just pass a stream object across appdomains, add it to the resource stream, then call the library.</p>

<p>Now I want to double-tap again to zoom out, but when I animate this with ScaleAnimation, the ImageView does not draw the newly exposed areas of the image (as the current viewport shrinks), instead you see the portion of visible image shrinking in. I have tried using ViewGroup.setClipChildren(false), but this only leaves the last-drawn artifacts from the previous frame - leading to an trippy telescoping effect, but not quite what I was after.</p>
<p>I know there are many zoom-related questions, but none cover my situation - specifically animating the zoom-out operation. I do have the mechanics working - ie aside from the zoom-out animation, double-tapping to zoom in and out works fine. </p>

1,103,739 | 1,103,740 | Is it possible to perform an assignment in a PHP return statement? | <p>I have a quick question regarding PHP's return statement. In C++, we're able to perform the following:</p>
<pre><code>... function body ...
return (foo = bar, biz());
</code></pre>
<p>Where the variable <code>bar</code> is assigned to <code>foo</code> before the result of <code>biz()</code> is returned.</p>
<p>Is this possible (or something similar) in PHP? The above statement in PHP results in a parse error. Now, I'm aware that I can simply perform the assignment before the return statement, but this is just a contrived example, and I'm curious as to the feasibility. </p>
<p><strong>Edit</strong>: Providing a little more clarification. Here is what I'm basically attempting to do in PHP:</p>
<pre><code>return ($foo = $bar, biz())
|| ($foo = $bar, baz())
|| ($foo = $bar, qux());
</code></pre>
<p><code>foo</code> is a global reference in which <code>biz</code> modifies. If <code>biz</code> returns false, the next segment in the OR statement is tested. Because <code>biz</code> returned false, I need to "reset" the value of <code>foo</code> before executing <code>baz</code> and so on and so forth. </p>
<p><strong>I'm aware that what I'm trying to do here is impure, but I'm just curious is an equivalent (or at least similar thing) is possible in PHP.</strong></p>

4,904,629 | 4,904,630 | Removing a class from an HTML element using JavaScript | <p>I am attempting to remove a class from an html tag using JavaScript but I have no idea where to start. I have searched but to no avail. While I am decently fluent in jQuery, I am not in JavaScript and I need to use JavaScript in this instance Anything I have found thus far would need to be adjusted for my own use, which I have not been successful at. Hopefully someone can explain it in a fool-proof way.</p>
<p>The element the class is attached to is the "ul" tag. The class is named "nojavaScript" and is only applied to this single instance of the "ul" tag. While as I said the class is only used once in the page, the "ul" tag is used in other instances with different classes or ids.
If it would make it easier for the JavaScript, I can change the class to an id.</p>
<p>I hope I have given you enough to go on. I will include an example of the html code below.</p>
<pre><code><ul id="lines_list" class="nojavaScript"></ul>
</code></pre>
<p>As I mentioned, if it's easier to remove an id than a class, I can make the current id a class, and the current class an id. But essentially it's the "nojavaScript" that needs to be removed.</p>
<p>Thanks!</p>

<p>I have obviously changed the names, so assume FooInfo is required and Name can't simply be a property of the class Foo.</p>
<p>Is there a more elegant way to write this method? I'm not very familiar with C# but I feel like there's an extension method or something which can turn this method into a 2-liner.</p>
<p>Note I'm looking for readability, it's not a contest to reduce the number of lines. I simply think the method would be more clear if C# had a way to search for the named <code>Foo</code> in one line.</p>

1,587,842 | 1,587,843 | How to check if my list has an item from another list(dictionary)? | <p>I'm a beginner in programming with python, and I've got a question which may have an easy answer.</p>
<p>So I have a dictionary of words which is imported from a .txt file, next my program asks you to type a sentence, and then it saves every word which you've typed into another list.</p>
<p>I have to write a program which checks if every word of a list named <code>sentence_list</code> is in the list which is named <code>words</code>. If the word is not present in the dictionary I have to put it in another list which is being filled by all the words that are mistyped or not in the dictionary.</p>
<p>For easier understanding, my program should work something like that:</p>
<pre class="lang-none prettyprint-override"><code>Type your sentence:
My naeme is John, I lieve in Italy, which is beatiful country.
</code></pre>
<pre><code>['naeme', 'lieve', 'beatiful']
</code></pre>
<p>This is what I could do until now:</p>
<pre><code>words = open("dictionary.txt", encoding="latin2").read().lower().split()
sentence=input("Type your sentence: ")
import re
sentence_list = re.findall("\w+", sentence.lower())
</code></pre>
<p>I know I have to do something with for, but for is different in python that it is in Javascript, which I am familiar with.</p>
