    <p>Using C++ 11 in Visual Studio 2012, I'm trying to sounds which I've observed in Pascal. In Pascal, it seems like you're able to send a frequency to the internal speaker, which plays this frequency until you tell it to stop (or until you tell it to play a different frequency). So here's what I need:</p> <ul> <li>I must be able to specify the frequency of the sound</li> <li>The sound must have little or no gap (up to maybe 5ms would be acceptable)</li> <li>I do not want to use external sound libraries (please do not waste my time by suggesting them, unless they are <strong>incredibly</strong> lightweight and provide an exceptionally wide range of use)</li> <li>Preferably, the sound would be played on internal speaker, rather than through the computer's regular speakers</li> </ul> <p>I can't find any include-able libraries/headers in visual studio which provide the ability to send a waveform to the internal speaker. I'm willing to try to work directly with the internal speaker (I know this would be hard, but I'm not an idiot - I think I can figure it out, with some guidance), but I can't find any documentation on accessing the internal speaker in Windows.</p> <p><strong>EDIT</strong>: From <a href="https://stackoverflow.com/questions/10216931/play-sound-on-internal-speakers-and-possibility-to-use-old-xp-api-function">this post</a>, I was able to gather that most computers nowadays don't actually have an internal speaker. Bummer. That's fine though - I can use the connected speakers, but I still have the following requirements:</p> <ul> <li>I need to be able to specify a frequency and have the speakers play that frequency until I tell them to stop</li> <li>I would rather not use external libraries</li> </ul> <p><strong>EDIT 2</strong>: Here's the class I'm working on:</p> <pre><code>#define HALF_NOTE 1.059463094359 // HALF_NOTE ^ 12 = 2 #include &lt;Windows.h&gt; #include &lt;math.h&gt; class SoundEffect { public: SoundEffect(){} void Play() { for (int i = 0; data[i + 1] &gt; 0; i++) { Beep(16 * pow(HALF_NOTE, data[i++] - 1), data[i] * 10); // (frequency of c0) * (twelfth root of 2) ^ (number of half steps above c0) // Ideally, the code would look more like this (pseudocode): // sound(16 * pow(HALF_NOTE, data[i++] - 1)); // Start playing the specified frequency // delay(data[i] * 10); } // nosound(); } int&amp; operator[] (int location) { return data[location]; } private: int data[256]; }; </code></pre>

    2. COBack in the day, those sounds were not played "directly on the sound card", but from the internal speaker. PCs mostly did not have sound cards until Pascal was not used any more.

    3. COMachines don't have speakers anymore. Guess why Beep() still works :)

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.
