Body
<p>I'm using Javascript to call a method on a Flash movie embedded in an ASPX page using SWFObject. It works fine in Firefox, but Internet Explorer 7 and 8 (so far) claim the object returned by <code>swfobject.getObjectById()</code> "doesn't support this property or method". I've found similar posts on this site and others, but nothing I've tried has fixed this in IE.</p> <p>ActionScript 3.0 class:</p> <pre><code>public class Player extends MovieClip { public function Player() { Security.allowDomain("http://localhost"); ExternalInterface.addCallback("test", test); } public function test():void { debugBox.appendText("test() called successfully\n"); } } </code></pre> <p>ASPX markup:</p> <pre><code><head runat="server"> <script type="text/javascript" src="Scripts/swfobject.js"></script> <script type="text/javascript"> swfobject.registerObject("myPlayer", "9.0.0", "scripts/expressInstall.swf"); </script> </head> <body> <form id="form1" runat="server"> <div class="movie"> <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="640" height="640" id="myPlayer"> <param name="movie" value="Player.swf" /> <param name="allowscriptaccess" value="always" />  <object type="application/x-shockwave-flash" data="Player.swf" width="640" height="640">  <a href="http://www.adobe.com/go/getflashplayer"> <img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" /> </a>  </object>  </object> </div> </code></pre> <p>Further along in the ASPX markup, the code that's trying to get the Flash object and call the <code>test()</code> method on it is happening in an AJAX callback from a third-party component (DevExpress ASPxHiddenField). This callback is triggered by user input after the Flash movie is loaded:</p> <pre><code> <dx:ASPxHiddenField ID="filenameHiddenField" runat="server" OnCustomCallback="filenameHiddenField_CustomCallback" SyncWithServer="False"> <ClientSideEvents EndCallback="function(s, e) { var playerObject = swfobject.getObjectById(&quot;myPlayer&quot;); playerObject.test(); }" /> </dx:ASPxHiddenField> </code></pre> <p>Internet Explorer complains about the last line in that function, "Object doesn't support this property or method".</p> <p>Thanks!</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.
