<p>I have forms in my page a get and a post and i want add pager on my get form .. so i cant page through the results.. </p>
<p>The problem that i am having is when i move to the second page it does not display anything..</p>
<p>I am using this library for paging ..
<a href="http://stephenwalther.com/Blog/archive/200... | <p>I'd recommend against doing paging via HTTP POST. Page and search criteria are 2 perfect examples of what querystrings are meant for. Put those values in the query string & have that load up your action args.</p>
<p>Think about this. You can search google for "pies", navigate to page 14, copy the link and se... | <p>Of course it will hit the GET version of SearchByAttraction because using this control you have a links as output.</p>
<p>So what you need to do:</p>
<pre><code>1. make form on the page:
<form id="myForm" action="your/url" method="post">
<input type="hidden" name="page" />

<p>When I try to bind port 80 to a socket in c, i always get the error, that I don't have permission to use this port. is there an easy way to get this permission?</p>
| <p>Usually only the superuser (root) can bind to 'privileged' ports (i.e. those port numbers below 1024).</p>
<p>This means that you either have to run your program as root or make your executable 'suid root'.</p>
<p>Both of these have security consequences so you may want to consider using the suid approach and reli... | <p>Yes, you can easily bind to port 80. Use Apache. Write a web application. Apache binds to port 80 and runs your web application. </p>
<p>Are you trying to write the next Apache? If so, you'll need to learn about the <a href="http://www.manpagez.com/man/2/setuid/" rel="nofollow noreferrer">setuid</a> API call i... | 20,411 |
<p>One of the things that seems to be necessary with use of STL is a way to specify local functions.
Many of the functions that I would normally provide cannot be created using STL function object creation tools ( eg bind ), I have to hand roll my function object.</p>
<p>Since the C++ standard forbids local types to b... | <p>The standard way is a "functor" - basically, a <code>struct</code> that supplies an <code>operator()</code></p>
<p>For example:</p>
<pre><code>struct MyMinFunctor {
bool operator()(const int& a, const int& b) { return a > b; }
};
vector<int> v;
sort(v.begin(), v.end(), MyMinFunctor());
</code><... | <p>With C++0x you can use lambda's (as you mentioned):</p>
<pre><code>for_each(container.begin(), container.end(),
[](auto item) {
// do something with item
}
);
</code></pre>
