    <p>I have 15 iframes in a web page.</p> <pre><code>&lt;iframe id="iframe0" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe1" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe2" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe3" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe4" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe5" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe6" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe7" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe8" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe9" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe10" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe11" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe12" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe13" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; &lt;iframe id="iframe14" style="left: 1px; visibility: visible; width: 100%; position: absolute; top: 23px; border: 1px solid #8db1e3;" frameborder="0" scrolling="auto"&gt;&lt;/iframe&gt; </code></pre> <p>Each of those iframes calls some web pages with huge amount of gridview in .NET. I am developing these pages using ASP.NET. Here my problem starts.</p> <p>I understand that iexplorer.exe is growing up since I load lots of data in these pages. It goes up to 400MB sometimes. But the problem is that even if I close the iframe which means... I make one of those iframes src = about:blank and make it display = none; However the size of iexplorer.exe's memory does not go down. It does not free the memory. How can I let the memory go down to normal? Actually, I have tested in IE8. But IE9 seems to be freeing the memory. I am not sure.</p> <p><strong>EDIT:</strong> I close the iframe as velow</p> <pre><code>document.all['iframe' + menuOrder[currentTab]].src = "about:blank"; document.all['iframe'+menuOrder[currentTab]].style.visibility="hidden"; </code></pre>

    1. COThere's really no need. You don't need to free physical memory in order for the operating system to use it for another purpose. And virtual memory is available in nearly unlimited supply and not usually worth the trouble of freeing. If you have an actual problem, other than seeing a number that you don't like, please tell us what it is and we'll help you fix it.

    3. CO@David Schwartz In fact, my pc is getting slow when the iexplorer.exe spends too much memory. That's the real problem.

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.

SQuiL has stopped working due to an internal error.

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