    <p>I have a timer thread that executes five seconds in the future and a loop to wait for it to finish executing. Then the program finishes when the user hits enter. I noticed that while waiting for the loop, enter is accepted into the input buffer, and used to finish the program, and any subsequent enter hits are entered <em>onto the command line</em>! </p> <p>I want to ignore all input that was entered before "press enter to exit" including enter. It's been a while since I worked with C++ and I can't remember how to do this (I have searched SO and Google and can't find an answer to this specific question). Here is the my example:</p> <pre><code>std::cout &lt;&lt; "Timer test: wait 5 seconds\n"; boost::asio::io_service test_io; deadline_timer test_timer(test_io, posix_time::seconds(5)); int testInt = 0; auto asynctest = [&amp;testInt](const boost::system::error_code&amp;) { std::cout &lt;&lt; "Running asynctest()\n"; testInt = 5; }; std::cout &lt;&lt; "Starting asynchtest, which should output in 5 seconds\n"; test_timer.async_wait(boost::bind&lt;void&gt;(asynctest, boost::asio::placeholders::error)); while(testInt != 5) { std::cout &lt;&lt; ". "; boost::this_thread::sleep(boost::posix_time::milliseconds(200)); } // How do I clear all input from the input stream here so that if the user hit enter // during the timer countdown it will be cleared and user still must hit enter to // exit program? std::cout &lt;&lt; "Press enter to exit\n"; std::cin.ignore(80, '\n'); return 1; </code></pre> <p>adsf</p>

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.
