C#: Should I bother checking for null in this situation?
|
<p>Lets say I have this extention method:</p>
<pre><code>public static bool HasFive<T>(this IEnumerable<T> subjects)
{
if(subjects == null)
throw new ArgumentNullException("subjects");
return subjects.Count() == 5;
}
</code></pre>
<p>Do you think this null check and exception throwing is really necessary? I mean, when I use the <code>Count</code> method, an <code>ArgumentNullException</code> will be thrown anyways, right?</p>
<p>I can maybe think of one reason why I should, but would just like to hear others view on this. And yes, my reason for asking is partly laziness (want to write as little as possible), but also because I kind of think a bunch of null checking and exception throwing kind of clutters up the methods which often end up being twice as long as they really needed to be. Someone should know better than to send null into a method :p</p>
<p>Anyways, what do you guys think?</p>
<p><hr /></p>
<p><strong>Note:</strong> <code>Count()</code> is an extension method and <em>will</em> throw an <code>ArgumentNullException</code>, not a <code>NullReferenceException</code>. See <a href="http://msdn.microsoft.com/en-us/library/bb338038.aspx" rel="nofollow"><code>Enumerable.Count<TSource> Method (IEnumerable<TSource>)</code></a>. Try it yourself if you don't believe me =)</p>
<p><hr /></p>
<p><strong>Note2:</strong> After the answers given here I have been persuaded to start checking more for null values. I am still lazy though, so I have started to use the <code>Enforce</code> class in <a href="http://abdullin.com/shared-libraries/" rel="nofollow">Lokad Shared Libraries</a>. Can recommend taking a look at it. Instead of my example I can do this instead:</p>
<pre><code>public static bool HasFive<T>(this IEnumerable<T> subjects)
{
Enforce.Argument(() => subjects);
return subjects.Count() == 5;
}
</code></pre>

My loop and File I/O
|
<p>How do I get my loop to write to the file until I stop the loop?</p>
<p>For example</p>
<pre><code>outFile = "ExampleFile.txt", "w"
example = raw_input(" enter number. Negative to stop ")
while example >= 0:
example = raw_input("enter number. Negative to stop")
outFile.write("The number is", example,+ "\n")
</code></pre>
<p>I feel like im hitting it close but I'm not sure. I wasn't sure how to search for this question in paticular. Sorry, I keep getting a error stating that the function takes 1 argument, when I enter more than 2.</p>
<pre><code>import os.path
outFile = open("purchases.txt","w")
quantity = float(raw_input("What is the quantity of the item :"))
cost = float(raw_input("How much is each item :"))
while quantity and cost >= 0:
quantity = float(raw_input("What is the quantity of the item :"))
cost = float(raw_input("How much is each item :"))
total = quantity * cost
outFile.write("The quantity is %s\n"%(quantity))
outFile.write("the cost of the previous quality is $s\n" %(cost))
outFile.close()
outFile = open("purchases.txt","a")
outFile.write("The total is ",total)
outFile.close()

How to use a blittable type representing a string
|
<p>I am trying to use the ReadUsingPointer Method described <a href="http://www.codeproject.com/Articles/25896/Reading-Unmanaged-Data-Into-Structures" rel="nofollow">here</a> to have a light spead binary reader for huge binary files. <br>However, the struct I am trying to pass to it contains strings. I was wondering how I could circumvent this and avoid the "cannot take the address of, get the size of, or declare a pointer to a managed type" message</p>
<p>I tried the following with no success so far (maybe having accessors to these fields is the problem?):</p>
<pre><code> [MarshalAs(UnmanagedType.LPStr)]
string s;
</code></pre>
<p>I have to specify that these string fields are used after reading and are not assigned while reading the bytes, so I do not need them while reading (I could use an intermediary struct without these fields but for legacy issues I can't do this).</p>

android developer console exception report platform not mentioned?

<p>I am new to android development. Recently I published a free app. after 70 to 80 downloads I have received a stack trace for a null pointer exception, </p>
<p>But the platform is not mentioned it only says 'Other'.</p>
<p>I am unable to reproduce the issue at my end and the stack trace is giving me no clue I have mentioned it here <a href="http://stackoverflow.com/questions/9929696/android-texttospeech-app-null-pointer-exception">Android TextToSpeech app null pointer exception</a>
. I would try to test it on the platform where the problem has occurred. </p>

Selecting all children and decendants with jQuery
|
<p>I have some HTML that is being produced by a WordPress plugin that is designed to allow for expandable/collapsible text, with up to three levels of depth. I would like it so that if you were to collapse the first or second levels and the children below it were also expanded those too would get collapsed but nothing I use seems to allow the selection of <em>all</em> children. This is what I'm using so far:</p>
<pre><code>$(".hidden-text-toggle").click(function () {
if ($(".hidden-text:animated").length) return false;
$(this).next().slideToggle();
if ($(this).hasClass('expanded') ){
$(this).removeClass('expanded');
$(this).animate({ backgroundColor: "black" , color: "red"});
}
else
{
$(this).addClass('expanded');
$(this).animate({backgroundColor: "red" , color: "black"});
}
return false;
});
<div class="wrapper">
<h2 class="title">Level One</h2>
<div class="text" href="#">
This is level one text.
<div class="wrapper">
<h2 class="title" href="#">Level Two</h2>
<div class="text">
This is level two text.
<div class="wrapper">
<h2 class="title" href="#">Level Three</h2>
<div class="text">
This is level three text.
</div>
</div>
</div>
</div>
</div>
</div>
</code></pre>
<p>I would have thought that putting something like <code>$(this).find(".text").slideUp();</code> after line 4 would allow this but apparently I am wrong. </p>
<p>Any help would be much appreciated!</p>

Language selection using images in PHP
|
<p>I have found an open source PHP script that uses a select menu to choose the language.</p>
<p>In the code session makes use of a loop to fill in the select menu, as above...</p>
<pre><code>$la = 0;
foreach($trans['languages'] as $short=>$langname) {
$params['LANGSEL'][$la]['LANG_SHORT'] = $short;
$params['LANGSEL'][$la]['LANG_LONG'] = $langname;
$la++;
}
</code></pre>
<p>In the php template creates the select menu like that...</p>
<pre><code><td><select class="select" name="lang"><#FOR LANGSEL#>
<option value="<#LANG_SHORT#>"><#LANG_LONG#></option>
<#/FOR LANGSEL#></select></td>
</code></pre>
<p>So this code works fine but i find it kinda ugly so i am trying to make an image input instead
So i thought something like that would work..</p>
<pre><code><input type="image" name="lang" value="http://localhost/index.php?lang=en" src=" <#IMAGES_DIRECTORY#>/english.png"></td>
<input type="image" name="lang" value="http://localhost/index.php?lang=it" src=" <#IMAGES_DIRECTORY#>/italian.png"></td>
</code></pre>
<p>But nothing changes, the page always shows up in italian that is the default language..
Thanks in advance from a newbie that is struggling to learn some html and php.</p>

Attempting all possible pairs on a grid and keep a record for improvements to sides matches
|
<p>Please go easy if I fail to explain anything.</p>
<p>Basically I wish to find out how I can keep a record of swapping all points in a tetravex grid. [ref: http://gamegix.com/tetravex/game].</p>
<p>I've created the grid and added the tiles from a random solution. I can currently swap ONE pair of USER-generated tiles but cannot do this as an automatic process.</p>
<p>How would one generally automate the process of swapping items automatically? AND keep a record of the "good" swaps</p>
<p>The swap method accepts the following parameters:</p>
<pre><code>ems.swap(i1, j1, i2, j2);
</code></pre>
<p>Where <code>i1,j1</code> is the first tile which you want to swap and <code>i2,j2</code> is the second tile you want to swap.</p>
<p>Once this is done, the tiles are assessed,</p>
<pre><code> public static int AssessSwapTiles(EdgeMatchSolution ems, EdgeMatch em)
{
int a = em.getRows();
int b = em.getColumns();
int swaptotal = 0;
for (int i = 0; i < a; i++)
{
for (int j = 0; j < b; j++)
{
int numSides = ems.sidesMatched(i,j);
System.out.print(numSides + " ");
swaptotal += numSides;
}
System.out.println();
}
System.out.println(swaptotal);
return swaptotal;
}
</code></pre>
<p>This method is called once before the swap and again AFTER the swap.</p>
<p>Apologies for a long explanation, it was only for those who would stumble upon on this in the future.</p>

I've discovered that I can't call <code>finish()</code> in <code>onPause()</code> in SearchPage2.java because I want the ListView to still be visible when you press my software back button (or the hardware Back Button) from SearchTaDa.java. But because I'm not calling <code>finish()</code> in SearchPage2.java, when you press the hardware home button to exit the app, then restart the app, it goes right back to the SearchPage2 activity rather than restarting the app from the splash screen, the beginning of the app. So the SearchPage2 onPause looks like:</p>
<pre><code> @Override
protected void onPause() {
super.onPause();
overridePendingTransition(R.anim.fadein, R.anim.fadeout);
}
</code></pre>
<p>and the More Info Activity, SearchTaDa.java onPause looks like:</p>
<pre><code> @Override
protected void onPause() {
super.onPause();
overridePendingTransition(R.anim.fadein, R.anim.fadeout);
finish();
}
</code></pre>
<p>My question is what can I call in the SearchPage2 activity so that when you restart the app it starts fresh, and doesn't resume at the search page?</p>

Javascript Settimeout problem
|
<p>In my application i am using asp.net3.5,ajax.dll.</p>
<p>I am calling all functionalities using ajax from javascript.</p>
<p>Sometimes i need to get the condition results from server side, only then i will be able to pass to next condition.</p>
<p>for the above case, javascript passes to next condition before executing the first condition.</p>
<p>So i added the following code to make it work,</p>
<p><code>setTimeOut("finddefaultvideo()",1000);</code>.</p>
<p>Can anyone please help me to get rid of this issue?</p>
<p>One thing i understood that,it won't wait for the time until server returns the value.</p>
<p>any idea to overcome the above one?</p>

Remove content and append class with jQuery
|
<p>I have to use a proprietary cms blog that renders it's "summary marker" that contains</p>
<ol>
<li>an elipsis</li>
<li>a dynamic changing link (so the link is always different)</li>
<li>static text that says: Click here to read more.</li>
</ol>
<p>This is how the summary marker currently renders on a page:</p>
<pre><code><p>Content goes here....<a href="example.htm">Click here to read more.</a></p>
<p>More content goes here....<a href="anothertest.htm">Click here to read more.</a></p>
<p>Content goes here....<a href="helloworld.htm">Click here to read more.</a></p>
</code></pre>
<p>Meanwhile, I would like to control the summary marker with some jquery so I'm not restricted to its rigid display by:</p>
<ol>
<li>removing each <code>ellipsis</code> </li>
<li>appending a <code>class</code> ONLY after the <code>href</code> that contained the ellipsis, so it doesn't update other links on the page.</li>
</ol>
<p>This would be the much desired expected result.</p>
<pre><code><p>Content goes here.<a href="example.htm" class="readmore">Click here to read more.</a></p>
<p>More content goes here.<a href="anothertest.htm" class="readmore">Click here to read more.</a>
<p>Content goes here.<a href="helloworld.htm" class="readmore">Click here to read more.</a>
</code></pre>
<p>Thanks so much for your help in advance!</p>
<p>This is what I got, which is bad I know</p>
<pre><code>$("p").html("...").remove:after.attr(".readmore").attr("href"));
</code></pre>

Way of loading dynamic content onload with Javascript
|
<p>On my page I load some tracks in a music player ( <a href="http://dev.upcoming-djs.com" rel="nofollow">http://dev.upcoming-djs.com</a> ) on page load.</p>
<p>Which is working fine.</p>
<p>However when people go to the following URL: <a href="http://dev.upcoming-djs.com/track/1/artist/title" rel="nofollow">http://dev.upcoming-djs.com/track/1/artist/title</a> I would like to load another track in the player on page load.</p>
<p>Currently the JS code for the player is:</p>
<pre><code>var tracks = [];
tracks.push({'url':trackurl, 'title':trackurl});
$('.upcoming-player-container').theplayer({
links: tracks // contains an array with url's
});
</code></pre>
<p>Which is static.</p>
<p>What would be the best way (not meant to be subjective, just don't know how to rephrase it) of making it dynamic.</p>
<p>I was thinking of adding some hyperlinks in a (hidden) container on the page which I retrieve with JS.</p>
<p>Is this a good way to do it? (Since I think Google might add the text to the search results).</p>
<p>Or perhaps there is a better way of doing it?</p>

ASP.NET 4.0 Website, want to put left menu in a file to edit from 1 file only
|
<p>I developed a website (I'm not a hard core programmer, but I can get by) using MS Visual Web Developer 2010. I love it! Stack people who responded to my 1st question recommended a new host, and that was a perfect recommendation.</p>
<p>Anyway, I have a navigational menu that I got from dynamicdrive on the left of every page. Currently, if I want to change the menu, I have to edit 24 different pages (a lot of copying and pasting!). I'd like to know if there's a way I can take the left menu, put it into a file (css? htm? Whatever the case ...), and then just put some type of or (??) type of tag there. This way, when I want to change the menu for the entire site, I just have to change 1 file.</p>
<p>Here's a picture I put on photobucket:
<a href="http://s1209.photobucket.com/albums/cc387/jdluski/?action=view&current=leftmenu.png" rel="nofollow">Picture of my left menu on my website (photobucket .png picture because I'm not allowed to upload pictures yet)</a></p>
<p>Also, whatever recommendation you have, I'll do the same to the footer, with our legal copyright and social bookmarking links.</p>
<p>Thanks a bunch Stack people!</p>

Javascript firefox issue
|
<p>I developed a .htm document with an in-built script for javascript to run a program. In google chrome, the program works fine, but I got a beta test complaint that it didn't work on firefox 14.01 or opera. On testing with firefox 14.01, I can confirm it doesn't work (I assumed opera to be the same). I cannot insist the audience upgrade their browsers, as this is supposed to be widely compatible.</p>
<p>Doing a little tracing of the issue, I installed Firebug, which, on clicking the Javascript button to generate a coordinate the first time, it worked (clearly showing the <em>function is defined and exists</em>), but the second time, Firebug complained that:</p>
<pre><code>"ReferenceError: GenerateCoord is not defined".
</code></pre>
<p>This wouldn't be so ironic if it only did this after generating an (encrypted) coordinate (thus calling GenerateCoord that is supposedly 'undefined').</p>
<p>If one looks in the code, one can clearly see that the function GenerateCoord is clearly defined before it is called. I would say firefox has an 'onclick' issue, but then it begs the question why did it work the first time I clicked it (calling GenerateCoord via 'onclick') but not the second?</p>
<p>Reloading the file allows the button to work the first time, and the first time only. I am baffled as to how firefox can call a function one time that it then says is undefined the next. Am I missing something here?</p>
<p>Javascript and HTML code can be viewed here:</p>
<p><a href="http://pastebin.com/4qykTfEW" rel="nofollow">http://pastebin.com/4qykTfEW</a></p>
<p>-</p>
<p>How do I solve the problem, and is there an easier solution than re-writing the code to avoid onclick (that seems to work in certain circumstances but not others)?</p>

Configure one app to be built using two Android name spaces?
|
<p>I have an app that, for release, needs building as two apps. The app will self-reconfigure based on the app's namespace, so I just need to build two versions, each with its own slightly different namespace.</p>
<p>I obviously want to avoid changing source code package names, and would like to change the name space in one place so building either version is quick and easy.</p>
<p>Can I simply change the package name in the <manifest> tag in the Android manifest, making sure my references are fully qualified? Are there any gotchas with doing this?</p>

Replace String Literals If/elseIf block with Enum
|
<p>I'm new to using Java Enums and I've read that replace IF logic that compares String literals should be replaced with an Enum. I don't quite understand how to replace my below code with an Enum, any ideas? Based on the col value being passed into applyEQ, I need to do a base the next method call on it's value. I do know the possible values of col ahead of time and I'm using a constants file for now. Should I create an Enum and place it in my Interface of Constants file?</p>
<pre><code>public class FilterHelper implements IFilterHelper {
private final EQuery eQuery;
public FilterHelper(EQuery query) {
eQuery = query;
}
@Override
public void applyEQ(String col, String val) throws Exception {
int return = 0;
if (col.equalsIgnoreCase(EConstants.NAME)) {
ret = Sample.addName(eQuery, val);
} else if (col.equalsIgnoreCase(EConstants.KEYWORDS)) {
ret = Sample.addKey(eQuery, val);
} else if (col.equalsIgnoreCase(EConstants.ROLE)) {
ret = Sample.addRole(eQuery, val);
}
if (return != 0) {
throw new Exception("failed");
}
}

<p><strong>this condition works fine</strong><br>
<strong>issue</strong>
i have an button in page once user clicks that button again if user selects any item[eg item1 is selected before clicking on the button. then after clicking the button. and now if we selected any item in checkboxlist the initially selected item1 is not getting deselected when i am selecting another item in check boxlist </p>
<p>below is my code</p>
<pre><code>var objChkd;
function HandleOnCheck()
{
var chkLst = document.getElementById('CheckBoxList1');
if(objChkd && objChkd.checked)
objChkd.checked=false;objChkd = event.srcElement;
}
</code></pre>
<p>and register the client event to the 'CheckBoxList1' at the Page_load as </p>
<pre><code>CheckBoxList1.Attributes.Add("onclick","return HandleOnCheck()");

Missing Data for Image

<p>I am loading an image from the internet using the following code:</p>
<p>NSURL *URL = [NSURL URLWithString:urlToImage];
NSData *data = [NSData dataWithContentsOfURL:URL options:0 error:&err]];
self.img = [[UIImage alloc] initWithData:data];</p>
<p>After the above:</p>
<p>self.img == nil, err == nil</p>
<p>No error, or no img.</p>
<p>I am suspecting that the data coming from the server is being truncated. THe data variable ends up being 850b but the image is 20K. </p>
<p>So, is there any reason data would be truncated?</p>

How to properly update a datatable while inside a loop
|
<p>In my below code I'm comparing values (email addresses) in my Arrarylist (called emails) with values in my Datatable (called dtResult). I was hoping to be able to remove rows from the datatable if it has an email address that is found in the arraylist but I'm starting to think I'm better off creating a new datatable that does not have those rows instead (I just don't know how to do that). Obviously my code below bombs after a row is deleted because it loses its place in the foreach loop. How can I fix this?</p>
<p>Thanks.</p>
<pre><code>foreach (DataRow row in dtResult.Rows)
{
var tmpl = row[3];
for (int x = 0; x < emails.Count; x++) //emails is an ArrayList of email addresses
{
string one = emails[x].ToString().ToUpper();
string two = tmpl.ToString().ToUpper();
//compare datatable value to arraylist value..
if (one == two)
{
//if they are equal then I want to remove them (or maybe create a new datatable??)
dtResult.Rows.Remove(row);
dtResult.AcceptChanges();
}
}
}

Problem is with previous button, when i click to previous button then it goes to previous button but i want earlier selected values by user to be bind with that radiobuttonlist. how i can do this? </p>

Which is the best way to get continues location updates from running background service with battery optimization?
|
<p>I have to create an app which runs a service in background and continually update the current location on the server or we can say i have to send my current location at some points. The solutions i have think are following. please look at that and give me some idea.</p>
<ol>
<li>Running an service in background with boot-starter.</li>
<li>Implementation of alarm manager so service can be started automatically if android kills it. </li>
<li>If my current location is in the radius of the 500 from my points than start to update on server.</li>
<li>and other logic which i have think to prevent continues server update.</li>
</ol>
<p>I have research on it and found it consumes much battery of phone. So please suggest me how can i optimized it.</p>

jQuery function queueing confusion
|
<p>I'm trying to understand exactly what it means when I put multiple calls in a row on jQuery, because I'm not getting the results I expect in similar situations.</p>
<p>Example 1:</p>
<pre><code>$(this).animate({opacity: 0.25}, 250).animate({opacity: 1.0}, 250);
</code></pre>
<p>As expected, this gives a quick flash of translucency before returning to full opacity.</p>
<p>Example 2:</p>
<pre><code>$(this).animate({opacity: 0.25}, 250).removeAttr("style");
</code></pre>
<p>In this case, instead of a gradual return to opacity, I would expect the removeAttr("style") to cause it to jump back to opacity after the animation is complete. This is because the animate opacity function merely changes values for <code>opacity</code> and sets <code>display:block</code>, and I would expect that by removing these styles, everything returns to normal.</p>
<p>Instead, it seems like the removeAttr is firing before the animation is complete, clears out the style, and then animation sets the opacity some more, leaving the item translucent. </p>
<p>The fact that this is the sequence of events would seem to be confirmed by the fact that altering the removeAttr to use a completion callback works properly:</p>
<pre><code>$(this).animate({opacity: 0.25}, 250, function(){$(this).removeAttr("style");});
</code></pre>
<p><b>Why is it that animations appear to be processed serially, while at least some functions are processed in parallel with the animations?</b></p>

Calling a variable from another class, issues with scope
|
<p>Ok I've narrowed down my problem but can't come up with a fix.</p>
<p>I want the first class to be able to reference variables from the second class.</p>
<pre><code>class TheFirstClass{
public function __construct(){
include 'SecondClass.php';
$SecondClass = new SecondClass;
echo($SecondClass->hour);
}
}
//in it's own file
class TheSecondClass{
public $second;
public $minute = 60;
public $hour;
public $day;
function __construct(){
$second = 1;
$minute = ($second * 60);
$hour = ($minute * 60);
$day = ($hour * 24);
}
}
</code></pre>
<p>But in this situation, only the "minute" is able to be accessed from the other class. If I were to remove the "= 60", then the minute would return nothing along with the rest of the variables.</p>
<p>The variables within the constructor are calculated correctly, but they do not affect the variables of the same name higher in the scope. Why, and what would be the correct way to structure the code instead?</p>

Why does "self" outside a function's parameters give a "not defined" error?
|
<p>Look at this code:</p>
<pre><code>class MyClass():
# Why does this give me "NameError: name 'self' is not defined":
mySelf = self
# But this does not?
def myFunction(self):
mySelf2 = self
</code></pre>
<p>Basically I want a way for a class to refer to itself without needing to name itself specifically, hence I want self to work for the class, not just methods/functions. How can I achieve this?</p>
<p><strong>EDIT:</strong> The point of this is that I'm trying to refer to the class name from inside the class itself with something like self.<strong>class</strong>._<em>name</em>_ so that the class name isn't hardcoded anywhere in the class's code, and thus it's easier to re-use the code.</p>
<p><strong>EDIT 2:</strong> From what I've learned from the answers below, what I'm trying to do is impossible. I'll have to find a different way. Mission abandoned.</p>
<p><strong>EDIT 3:</strong> Here is specifically what I'm trying to do:</p>
<pre><code>class simpleObject(object):
def __init__(self, request):
self.request = request
@view_defaults(renderer='string')
class Test(simpleObject):
# this line throws an error because of self
myClassName = self.__class__.__name__
@view_config(route_name=myClassName)
def activateTheView(self):
db = self.request.db
foo = 'bar'
return foo

Problem with getElementsByClassName
|
<p>Following code is causing the problem:</p>
<pre><code>var CheckBoxes = document.getElementsByClassName('DeleteCheckBox')
for (var i = 0; i < CheckBoxes.length; i++) {
CheckBoxes[i].checked = false;
}
</code></pre>
<p>Well, the checkboxes are still selected after this runs. And it runs, because I checked the i variable and it is counting.</p>
<p>What is wrong here? By the way, only checkboxes have the "DeleteCheckBox" class, so only checkboxes get returned by getElementsByClassName.</p>
<p>SOLVED:</p>
<p>I've found the problem. I am using asp.net and the framework seems to assign the class to the "label" (it creates a span tag) of the checkbox, not to the input.</p>
<p>Fixed with InputAttributes.Add("class", "DeleteCheckBox"); (asp.net codebehind)</p>
