4,372,347 | 4,372,348 | Adding the same function to many elements (using js prototypes?) | <p>In my application, I receive a collection of Comments with JSON.</p>
<p>Then, I want to add functions to every item in this collection, so for example if a Comment has <code>comment.first_name</code> and <code>comment.last_name</code>, I want to build <code>comment.full_name()</code>.</p>
<p>So far, I'm doing:</p>
<pre><code>comment.full_name = function() { return this.first_name+" "+this.last_name }

3) Click on Tab "Directory Security"<br>

304,085 | 304,086 | Crazy talk (paranoid about initialization) | <p>I learned long ago that the only reliable way for a static member of be initialized for sure is to do in a function.

static int dataMember = 0;
return dataMember;

<p>The other way is to put the definition in a translation unit and keep the stuff out of the header file. I have nothing against that per se but I have no idea what the standard says regard when and under what circumstances that is safe.</p>

4,081,815 | 4,081,816 | Removing useable time slots from an array | <p>I'll ask my question in a moment first allow me to explain what I've done and am trying to accomplish.</p>
<p>Goal: Only show times that are available for a service to be booked on a muli-staff calendar.The import thing here is that services have minimum booking times (in minutes) </p>
<p>Approach:</p>
<p>Steps</p>
<p>1) Create an array of all possible times someone could start a booking (i.e, 9am-5pm where each key increase by a set interval (i.e, 5min,9:05, 9:10,etc)</p>
<p>2) Load each staffs bookings for that day into an array and intersect these arrays so you find out if at least one person is available at a certain time. </p>
<p>3) Generate an array that is the difference of available hours in the day with the result of the intersected staff bookings.</p>
<p>Where the problem lies...</p>
<p>If staff member "Mary" has a booking from 9:15 - 9:45 and John has an appointment from 9:00 - 9:30. It will show '9:00' as being available although it's only available from 9:00-9:15 .
Which doesn't work because in this case the minimum booking time is 30mins.</p>
<p>Question:</p>
<p>I have an array of hours: minutes at an set interval (5 mins). How do I remove blocks of time that are two short ?</p>

600,133 | 600,134 | Can I call constructor within an arithmetic expression? | <p>I am implementing a Matrix class and I overloaded the <code>*</code> and <code>+</code> operators. I also have a constructor:</p>
<pre><code>Matrix (int row, int col, const elemType &init_val)
</code></pre>
<p>that constructs a matrix initialized to hold init_val in all positions. So based on this implementation, I have in my test program:</p>
<pre><code> Matrix<int> mi4 = Matrix<int> (2, 2, 3) + Matrix<int> (2, 2, 1);
</code></pre>
<p>The compiler gives me the following error:</p>
<pre><code>testMatrix.cpp:41: error: ambiguous overload for ‘operator+’ in ‘Matrix<int>(2, 2, ((const int&)((const int*)(&3)))) + Matrix<int>(2, 2, ((const int&)((const int*)(&1))))’

webView.loadUrl("file:///android_asset/index.html");
</code></pre>
<p>So at different points in time, a user may look at index.html, page1.html, etc. From what I can tell, only the JavaScript in index.html has access to the JavaScriptInterface via "window.android.someMethodName()". When I try to make a call to "window.android.someMethodName()" from page1.html, it says that "window.android" is not defined.</p>
<p>so the user starts the webview from
login.html page and navigates through different pages..
my requirement is in the last page of my webpage i have a button saying return to android activity. so when user clicks on the last page of my navigation the user has to come back to the android activity.</p>
<p>window.android.someMethodName()" can be called in html page which works fine. but this method will work if i call this method only from the first page which i loaded ie from the login.html page only this method will work.. if i call this method from the last page of the webview naviagation this is not working.</p>

4,174,836 | 4,174,837 | Function to generate alpha numeric sequence number based on input number | <p>I am trying to develope a routine in C# that will take a given input integer and return a 6 character alpha numeric string based on a predefined possible set of characters.</p>
<p>The possible characters to use are: </p>
<p>"0123456789ABCDEFGHJKLMNPQRSTUVWXYZ" (note that the letter "I" and "O" are not in the set.)</p>
<p>Therefore given the input of 1, the output should be "000001", input of 9 would output "000009", input of 10 would output "00000A", input of 12345 would output "000AP3", and so on.</p>
<p>I am having a hard time coming up with an elegant solution to this problem. I know I must be approaching this the hard way so I'm looking for some help.</p>

3,947,129 | 3,947,130 | PHP output buffer is not empty? | <p>I have this peculiar problem. I am making an AJAX call to a PHP page. In case of error I am returning the string "error" to success: <code>function(msg)</code> i.e. msg will have the value "error". But for some reason it is sending back "error" but with a line break preceding it. And this fails the condition when i check <code>if (msg=="error")</code>. I have to put <code>ob_clean()</code> to clear out the output buffer. Then it returns "error" without line break. I checked but my PHP function is not outputting anything before the "error". What can be the issue that the output buffer is not empty?</p>

1,546,954 | 1,546,955 | Custom Sorting Python Dictionary | <p>So I have a dictionary that looks like this when I print it:</p>
<pre><code>{'10': -10, 'ZT21': 14, 'WX21': 12, '2': 15, '5': -3, 'UM': -25}
</code></pre>
<p>I want to sort these in a custom manner, which I define. Let's say the way I want it to be sorted (by key) is <code>ZT21</code>, <code>10</code>, <code>WX21</code>, <code>UM</code>, <code>5</code>, <code>2</code>.</p>
<p>Anyone know how to go about sorting out a dictionary in a predefined/custom manner? What I am doing is getting this dictionary from a database, and it can come out with over 20 keys, all of which have a specific order. The order is always set, but sometimes certain keys/values wouldn't be in the dictionary. So this could happen too:</p>
<pre><code>{'ZT21': 14, 'WX21': 12, '2': 15, '5': -3, 'UM': -25}
</code></pre>
<p>sorted (by key) is <code>ZT21</code>, <code>10</code>, <code>WX21</code>, <code>UM</code>, <code>5</code>, <code>2</code>.</p>
<p>So the 10 isn't there in this example, but the sorting I need is still the same, the 10 would just be absent.</p>
<p>Any ideas?</p>
