    <p>I have 2 projects. One is built by C++ Builder without MFC Style. And other one is VC++ MFC 11.</p> <p>When I create a thread and create a cycle -- let's say this cycle adds one to progressbar position -- from 1 to 100 by using <code>Sleep(10)</code> it works of course for both C++ Builder and C++ MFC.</p> <p>Now, <code>Sleep(10)</code> is wait 10 miliseconds. OK. But the problem is only if I have open media player, Winamp or anything else that produces "Sound". If I close all media player, winamp and other sound programs, my threads get slower than 10 miliseconds.</p> <p>It takes like <code>50-100 ms / each</code>. If I open any music, it works normally as I expected.</p> <p>I have no any idea why this is happening. I first thought that I made a mistake inside MFC App but why does C++ Builder also slow down?</p> <p>And yes, I am positively sure it is sound related because I even re-formated my windows, disabled everything. Lastly I discovered that sound issue.</p> <p>Does my code need something?</p> <p><strong>Update</strong>:</p> <p><s>Now, I follow the code and found that I used <code>Sleep(1)</code> in such areas to wait 1 miliseconds. The reason of this, I move an object from left to right. If I remove this sleep then the moving is not showing up because it is very fast. So, I should use <code>Sleep(1)</code>. With <code>Sleep(1)</code>, if audio is <strong>on</strong> than it works. If audio is <strong>off</strong> than it is very slow.</p> <pre><code>for (int i = 0; i &lt;= 500; i++) { theDialog-&gt;staticText-&gt;SetWindowsPosition(NULL, i, 20, 0, 0); Sleep(1); } </code></pre> <p>So, suggestions regarding this are really appreciated. What should I do?</p> <p>I know this is the incorrect way. I should use something else that is proper and valid. But what exactly? Which function or class help me to move static texts from one position to another smoothly?</p> <p>Also, changing the thread <strong>priority</strong> has not helped. </s></p> <p><strong>Update 2</strong>:</p> <p>Update 1 is an another question :)</p>

    1. COInteresting. Is the priority of your process still the same when you notice the difference?

    2. COPriorities of processes are same. The second interest thing is, if i open media player (but not play a music) my thread program runs with 2% of CPU and thread works. If i close media player, instantly slow down and it takes 0% of CPU.

    3. COThis could be due to processors throttling the frequency of the cpu.

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.
