<p>You can see that this is a : seperated string which contains Records which are comma seperated fields.</p>
<p>I am looking for the best (fastest) way that split the string in given number of chunks and take care that one chunk should contain full record (string upto ':')</p>
<p>or other way of saying , there should not be any chunck which is not ending with :</p>
<p>e.g. 20 MB string to 4 chunks of 5 MB each with proper records (thus size of each chunk may not be exactly 5 MB but very near to it and total of all 4 chunks will be 20 MB) </p>
<p>I hope you can understand my question (sorry for the bad english)</p>
<p>I like the following link , but it does not take care of full record while spliting also don't know if that is the best and fastest way.</p>

<p>I still don't have anything being written to the new file. I think a problem might be that in the full file the id numbers have a " in front of them but this doesn't exist in the listfile. Any thoughts?</p>

3,956,011 | 3,956,012 | how to compare two files and extract the difference? | <p>I created a video recorder which stores recording to a file. I would like to implement a method which would read the file each second, compare the current file with the old value (1 second older) and write the difference to a separate file.</p>
<p>I would be very thankful if anyone could explain how to do that or write a simple example. I guess there has to be a thread which compares the new value with the old one by calling a custom method compareFiles(File currentFile, File oldFile) on a given period of time. The old file could also be saved as a temporary file and the current file at the original path could be compared with temporary file.</p>

1,031,919 | 1,031,920 | Parsing sequential ASCII file for editing - Visual C# | <p>I have been recently assigned a task in which I need to create a program to edit files in Visual C#. The file is a sequential ASCII text file with multiple fixed character width rows, and the basic structure looks like this: </p>
<p>Each group is a single parameter, and there can be hundreds of these within a file. Each PA has a set number of columns, but each PA varies in column numbers. Additionally, there are some optional fields within each record, so that accounts for the extra spaces between some of the fields. Each field also has a separator of 1 space. I am unsure if I am being too thorough, but I figure the more information I give, the easier it will be for someone to help me.</p>
<p>Essentially, I want to create a GUI in which the user can select one a parameter mnemonic and then be able to edit any of the fields within the entire group of parameters</p>
<p>I have a little C# experience, but I am having trouble figuring out what would be the best way to accomplish this. My initial thinking was to parse the file into an array, search for each parameter name (maybe using regular expressions?), display all the parameter names in a browser. From there the user would be able to select which parameter they wish to edit. The program would then search the array again for the selected parameter, and then parse the records into text boxes, to allow for editing. </p>
<p>I am unsure if this is the most efficient way of accomplishing this, and I am somewhat stuck on how to actually parse the file to read the fields into the text boxes. I have searched many different forums for file parsing, but most of the topics I find related to comma delimited files which does not really apply to the file type I am working with. Any help would be greatly appreciated, and if you need me to elaborate on anything, please feel free to ask me. Thank for the help.</p>

3,130,752 | 3,130,753 | Does foreach do its work on a copy of the input array? | <p>I've been studying some test questions. One of the questions about array iteration. Here it is : </p>
<blockquote>
<p>What is the best way to iterate through the $myarray array, assuming
you want to modify the value of each element as you do?</p>
<pre><code><?php
$myarray = array ("My String",
"Another String",
"Hi, Mom!");
?>
</code></pre>
<p>A. Using a for loop</p>
<p>B. Using a foreach loop</p>
<p>C. Using a while loop</p>
<p>D. Using a do…while loop</p>
<p>E. There is no way to accomplish this goals</p>
</blockquote>
<p>My answer is "of course foreach loop". But according to the answer sheet :</p>
<blockquote>
<p>Normally, the foreach statement is the most appropriate construct for
iterating through an array. However, because we are being asked to
modify each element in the array, this option is not available, since
foreach works on a copy of the array and would therefore result in
added overhead. Although a while loop or a do…while loop might work,
because the array is sequentially indexed a for statement is best
suited for the task, making Answer A correct.</p>
</blockquote>
<p>I still think foreach is the best. And as long as I use it with key I can modify values.</p>
<pre><code><?php
foreach($myarray as $k=>$v){
$myarray[$k] = "Modified ".$v;
}
?>
</code></pre>

// SoyTofu's newRenderer method returns an object that can render any template in file set.
SoyTofu tofu = sfs.compileToJavaObj();

949,632 | 949,633 | OO Javascript and this keyword. Object Literals | <p>I'm having issues with Javascript properties and "this" keyword. Forgive me here for asking my third and final JS OOP question. OOP in Javascript has been a headache for me today.</p>
<p>I'm trying to set the property 'source' but the error console is saying it's undefined in parseSource method.</p>
<p>After a little research I believe this.source is is referring to window.source? The code is a boilerplate from Mozilla. When creating extensions init is called by FireFox when the plugin is initialized.</p>
<p>What's the best way to go about setting the properties when creating objects using literal notation?</p>
<pre><code>var myExtension = {
source: null,
init: function() {
// The event can be DOMContentLoaded, pageshow, pagehide, load or unload.
if(gBrowser) {
gBrowser.addEventListener("DOMContentLoaded", this.onPageLoad, false);
}
},
onPageLoad: function(aEvent) {
doc = aEvent.originalTarget; // doc is document that triggered the event
win = doc.defaultView; // win is the window for the doc
// Skip frames and iFrames
if (win.frameElement) return;
this.source = win.document.getElementById('facebook').innerHTML;
myExtension.parseSource();
},
parseSource: function() {
if(this.source == null) {
// So something
} else {
// Do something else
}
}
}
window.addEventListener("load", function() { myExtension.init(); }, false);

5,855,571 | 5,855,572 | php function variable scope | <p>I was wondering if i have a function like this:</p>
<pre><code>function isAdmin ($user_id) {
$admin_arr = array(1, 2);
foreach ($admin_arr as $value) {
if ($value == $user_id) {
return true;
}
}
return false;
}

<p>Could i make an array outside of that function as a global array and use it inside the function without sending it through as a parameter, also instead declaring a new admin array inside the function as i just did above? How would i do this? </p>

1,368,148 | 1,368,149 | "nice" keyword in c++? | <p>So I was doing some simple C++ exercises and I noticed an interesting feat. Boiled down to bare metal one could try out compiling the following code:</p>

int main()
{
nice n;
return 0;
};
</code></pre>
<p>The result is a compilation error that goes something like this:</p>

<file>.cpp:11: warning: statement is a reference, not call, to function ‘nice’
<file>.cpp:11: warning: statement has no effect
</code></pre>
<p>And this was using regular g++ on Max OS X, some of my friends have tried in on Ubuntu as well, yielding the same result.</p>
<p>The feat seems to lie in the word "nice", because refactoring it allows us to compile. Now, I can't find the "nice" in the keyword listings for C++ or C, so I was wondering if anyone here had an idea?</p>
<p>Also, putting</p>
<pre><code>class nice n;
