There is a function that, when the "start" box is clicked, selects one of the two elements randomly, and, depending on which is chosen, displays either a yellow or reddish box. </p>
<p>However, in actual fact, it is always the yellow box that is selected, so something is not working.</p>
<p>However, the exact same code that selects things randomly works in other contexts (see <a href="http://jsfiddle.net/urfXq/96/" rel="nofollow">http://jsfiddle.net/urfXq/96/</a> ), so I don't know what the problem is... </p>

5,050,345 | 5,050,346 | Properties backing field - What is it good for? | <p>On one hand, I know that the advisable usage of Properties is to have a backing field, like in the following example:</p>

get { return m_Capacity > 0 ? m_Capacity : -666; }
set { m_Capacity = value; }

get { return Capacity > 0 ? Capacity : -666; }
set { Capacity = value; }
}

Also do you need the permssion of the website owner to incorporate such a link into your app. I would have thought the anser is no as it is a publically available website, but I just wanted to make sure.

<p>It turns out that the innerHTML causes internet explorer 8 to say that innerHTML is null or not an object. Thinking that this may be a bug with IE I updated to IE9. Still have the same problem. However, if I add the line before the 'if':-</p>

<p>it works, as if innerHTML is recognised. Got no idea how the two commands are related. The only thing is that I do not want to display the contents of 'parent', as this would make the web page untidy. Any clues?</p>

There is one method "getCommandValue" method available but not working with Firefox.
"getComputedStyle" method gives style of the object and not of selected text in div.
Please suggest. It's urgent.

<a href="http://stackoverflow.com/questions/7048888/stdvectorstdstring-to-char-array">std::vector<std::string> to char* array</a> </p>
</blockquote>
<p>I have to call a c function that accepts an array of string pointers. Example</p>
<pre><code>void cFunction(char* cities[], int count)
{
for(int i = 0; i < count; ++i )
{
printf("%s\n", cities[i]);
}
}
</code></pre>
<p>Assume that function is in some third party libabry; it cannot be changed<br>
I can declare a static array and call the function like this<br></p>
<pre><code>char* placesA[] = {"Teakettle Junction", "Assawoman Bay", "Land O' Lakes", "Ion", "Rabbit Hask" };
cFunction(placesA, 5);
</code></pre>
<p><br>
That works. But my data is dynamic i.e. the size of the array changes many times at runtime<br>
So I tried this<br></p>
<pre><code>std::vector<std::string> placesB(placesA, placesA + 5);
cFunction(&placesB[0], 5); // this won't work because std::string != char*[]
</code></pre>
<p><br>
Tried this <br></p>
<pre><code>std::vector<char*> placesC;
cFunction(&placesC[0], 5);
</code></pre>
<p>I find <code>placesC</code> awkward to populate at the sametime avoid memory leaks<br> I am looking for a solution that is both efficient ( as little string copying as possible and preferably uses STL and or Boost )</p>

807,623 | 807,624 | Handling the different results from parsedatetime | <p>I'm trying to learn python after spending the last 15 or so years working only in Perl and only occasionally.</p>
<p>I can't understand how to handle the two different kinds of results from the parse method of Calendar.parse() from parsedatetime</p>
<p>Given this script:</p>
<pre><code>#!/usr/bin/python
import parsedatetime.parsedatetime as pdt
import parsedatetime.parsedatetime_consts as pdc
import sys
import os
# create an instance of Constants class so we can override some of the defaults
c = pdc.Constants()
# create an instance of the Calendar class and pass in our Constants # object instead of letting it create a default
p = pdt.Calendar(c)
while True:
reply = raw_input('Enter text:')
if reply == 'stop':
break
else:
result = p.parse(reply)
print result
print
</code></pre>
<p>And this sample run:</p>
<blockquote>
<p>Enter text:tomorrow<br>
(time.struct_time(tm_year=2009, tm_mon=11, tm_mday=28, tm_hour=9, tm_min=0, tm_sec=0, tm_wday=5, tm_yday=332, tm_isdst=-1), 1) </p>
<p>Enter text:11/28<br>
((2009, 11, 28, 14, 42, 55, 4, 331, 0), 1) </p>
</blockquote>
<p>I can't figure out how to get the output such that I can consisently use result like so:</p>
<pre><code>print result[0].tm_mon, result[0].tm_mday
</code></pre>
<p>That won't work in the case where the input is "11/28" because the output is just a tuple and not a struct_time. </p>
<p>Probably a simple thing.. but not for this newbie. From my perspective the output of Calendar.parse() is unpredictable and hard to use. Any help appreciated. Tia.</p>

<input type="password" id="password" value="PASSWORD" onfocus="inputFocused(this)" onblur="inputBlurred(this)" />
