    <p>Wish to simultaneously call a function multiple times. I wish to use threads to call a function which will utilize the machines capability to the fullest. This is a 8 core machine, and my requirement is to use the machine cpu from 10% to 100% or more. </p> <p>My requirement is to use the boost class. Is there any way I can accomplish this using the boost thread or threadpool library? Or some other way to do it?</p> <p>Also, if I have to call multiple functions with different parameters each time (with separate threads), what is the best way to do this? [using boost or not using boost] and how?</p> <pre><code>#include &lt;iostream&gt; #include &lt;fstream&gt; #include &lt;string.h&gt; #include &lt;time.h&gt; #include &lt;boost/thread/mutex.hpp&gt; #include &lt;boost/bind.hpp&gt; using namespace std; using boost::mutex; using boost::thread; int threadedAPI1( ); int threadedAPI2( ); int threadedAPI3( ); int threadedAPI4( ); int threadedAPI1( ) { cout &lt;&lt; "Thread0" &lt;&lt; endl; } int threadedAPI2( ) { cout &lt;&lt; "Thread1" &lt;&lt; endl; } int threadedAPI3( ) { cout &lt;&lt; "Thread2" &lt;&lt; endl; } int threadedAPI4( ) { cout &lt;&lt; "Thread3" &lt;&lt; endl; } int main(int argc, char* argv[]) { boost::threadpool::thread_pool&lt;&gt; threads(4); // start a new thread that calls the "threadLockedAPI" function threads.schedule(boost::bind(&amp;threadedAPI1,0)); threads.schedule(boost::bind(&amp;threadedAPI2,1)); threads.schedule(boost::bind(&amp;threadedAPI3,2)); threads.schedule(boost::bind(&amp;threadedAPI4,3)); // wait for the thread to finish threads.wait(); return 0; } </code></pre> <p>The above is not working and I am not sure why? :-(</p>

    1. COIt's always a good idea to specify *how* it is "not working". It doesn't do what you want? It doesn't compile? What errors do you get? Where exactly do you get them?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
