621,545 | 621,546 | C# join 2 or more classes together? | <p>So this might sounds like a n00b question, but I want to take 2 classes and merge them together. </p>
<p>Like so :</p>
<pre><code>Ball oneBall = new Ball("red", 20);
Ball anotherBall = new Ball("blue",40);
Ball BigBall = new Ball(oneBall + anotherBall);
BigBall.size() //should say 60 right?
</code></pre>
<p>I know you would have something like this</p>
<pre><code>class Ball{
public Ball(string Name , int size){}
// But to merge to of them?
public Ball(Ball firstBall, Ball secondBall){} //I know the arguments have to be added
{}
}
</code></pre>
<p>So my question is what is the overload(right?) suppose to look like?</p>
<p>Thanks,</p>

1,475,760 | 1,475,761 | Stop PHP STRPOS function from ignoring zeros | <p>I am creating a script that will find files from an input file (right now I am working on a jpg).</p>
<p>I use common file headers/trailers/structure to find the data that needs to be extracted. I use STRPOS to find these commonalities and find the parts of the file that need to be copied from the rest of the data etc etc.</p>
<p>Anyways, I am running into an issue, STRPOS is supposed to be looking for the string, "FFD9"... however it is finding it in incorrect positions!</p>
<p>For example, my hex in my JPG file looks as such,</p>
<p><img src="http://i.stack.imgur.com/SjXZs.png" alt="Wrong String!"></p>
<p>See the FF and the D9 on each side of the zero? STRPOS seems to be ignoring that 00 in-between! I need this to stop for my script to work correctly.</p>
<p>Any idea or suggestions? Thank you very much!</p>

2,436,714 | 2,436,715 | Elegant solution to retrieve custom date and time? | <p>I am currently using a date and time picker to retrieve a user-submitted date and time, and then I set a control's text to the date and time selected. </p>
<p>I am using the following code:</p>
<pre><code>new DatePickerDialog(newlog3.this, d, calDT.get(Calendar.YEAR), calDT.get(Calendar.MONTH), calDT.get(Calendar.DAY_OF_MONTH)).show();
new TimePickerDialog(newlog3.this, t, calDT.get(Calendar.HOUR_OF_DAY), calDT.get(Calendar.MINUTE), true).show();
optCustom.setText(fmtDT.format(calDT.getTime()));
</code></pre>
<p>Now, while the above code block does bring up the date and time widgets and sets the text, the code block is being executed in full before the user can select the date.. ie: It brings up the date box first, then the time box over that, and then updates the text, all without any user interaction. I would like the date widget to wait to execute the time selector until the date selection is done, and i would like the settext to execute only after the time widget is done. </p>
<p>How is this possible? Or is there is a more elegant solution that is escaping me?</p>
<p>Edit: This is the code for DatePickerDialog/TimePickerDialog which is located within the class:</p>
<pre><code> DatePickerDialog.OnDateSetListener d=new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
calDT.set(Calendar.YEAR, year);
calDT.set(Calendar.MONTH, monthOfYear);
calDT.set(Calendar.DAY_OF_MONTH, dayOfMonth);
//updateLabel();
}
};
TimePickerDialog.OnTimeSetListener t=new TimePickerDialog.OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hourOfDay,
int minute) {
calDT.set(Calendar.HOUR_OF_DAY, hourOfDay);
calDT.set(Calendar.MINUTE, minute);
//updateLabel();
}
};

1,464,979 | 1,464,980 | Call function from another function | <p>I'm writing a calendar in Javascript, and I want to know how to get the calendar to call itself depending on which link the user clicks. At the moment the function has the name foo()</p>
<p>At the bottom, there are three different div links which are displayed depending on given circumstances. The (working) calendar was written in PHP, so I'm trying to port it into Javascript. Doing pretty well with that, but there's a few bugs that need ironing out. The problem is I just have to mimic the behavior of the PHP calendar, which sent POST values to the next or previous buttons to use as information for which month to display (etc).</p>
<p>I have tried this in two different ways with the Javascript calendar, first using a javascript void (onclick) link which called the calendar function, but apparently you can't pass variables to a function with onclick. The other way was using dom objects, but I faced a new dilemma: you can't call a function within itself.</p>
<p>So, how would I go about calling a function, by making another function and then calling the calendar from inside that one?
Thanks.</p>
<p>SystemError</p>
<p>An example:</p>
<pre><code> function cal()
{
document.write("<td align='left' colspan=7><div id='calendar'></div></td>");
(function()
{
var lastday = cal[month];
DOMcalendar = document.getElementById("calendar"),
div = document.createElement("div");
div.innerHTML = "<a href='javascript:void(0)'>Next</a>";
div.onclick = function()
{
cal(lastday);
}
DOMcalendar.appendChild(div);
})()
}
cal();

<p>I have a custom <code>listview</code> working with a <code>time value</code> and some <code>buttons</code> to click in it. I currently have the time updated every second via <code>notifyDataSetChanged()</code> in a one second handler method. </p>
<p>This works nicely in updating the time. Unfortunately though it means the views are recreated every second. This means my button press operation isn't very responsive as each time the view is regenerated the button is reset. So if you are pressing a button while the view changes, the press becomes invalid and you have to release the button and then press it again. With a long press the problem is even worse as there isn't enough time to register a long press before the view is regenerated. So a long press never happens. </p>
<p>Is there a way to change data within the listview without have to regenerate the whole view? </p>

2,747,800 | 2,747,801 | Making a browser and node compatible Javascript library | <p>I am attempting to make a javascript library which I would prefer to be compatible with both browsers and node. However, there is some functionality offered in the node API that isn't offered in browsers (such as compression). I know it would be possible to code this functionality in javascript so it would be cross-compatible, but the node native compression will probably perform much better as it is much lower level.</p>
<p>How should I split between browser-compatible code and code that uses node API?</p>
<p>The way I see it, I could do one of the following:</p>
<ul>
<li>make 2 separate scripts, one for node and one for browsers</li>
<li>make my code figure out the environment it is in and act accordingly</li>
<li>make all my code the same, but lose some performance improvements I would have had in node</li>
</ul>
<p>What should I do to solve this?</p>

dataType: 'text',
success: function (data) {

338,384 | 338,385 | How to set focus to a web control in ASP.NET | <p>Question: What is the best way to set focus to a web control in ASP .NET.</p>
<p>I can do it, but it's ugly. I have a web control wrapped in a web control hosted on a web page. So, if you do a view | source on the page the id is something like WrapperControl_Control_TextBox.</p>
<p>I've tried the "tried and true" Javascript methods of grabbing the element and setting it's focus: document.getElementByID( "WrapperControl_Control_TextBox" ).focus(); and it didn't work. I'm not sure why.</p>
<p>I know I could possibly do:
document.getElementById( "<%= TextBox.ClientID %>" ).focus(); too, I think. This won't work because of another totally separate error based on the fact you can't dynamically add controls to a header if there is a "<% %>" in the page. GAH.</p>
<p>In the "bottom-most" control, I've tried setting the focus (TextBox.Focus() in Page_Load) and that doesn't work either.</p>
<p>Anyway, the way that works is by simply taking the ControlsCollection of the Page, grabbing the control I need from that, getting it's collection, grabbing the next lower control and so forth.</p>
<p>I only have to do this seven times. So I have eight foreach loops.</p>
<p>Basically, my code is like this:</p>
<p>///////////////////////////////
// On the page
///////////////////////////////</p>
<pre><code>ControlCollection controls = Controls;
foreach( Control control in controls)
{
if ( string.Equals( control.ID, "FormID", StringComparison.InvariantCultureIgnore ) )
{
ControlCollection nextControls = control.Controls;
foreach( Control nextControl in nextControls )
{
if ( string.Equals( nextControl.ID, "DivICareAboutInTheForm", StringComparison.InvariantCultureIgnor ) )
{
ControlCollection nextNextControls = nextControl.Controls;
//:
//:
//Yes, it's that bad and so forth.
//:
//:
}
}
}
}
