    <p>I am getting the <code>HRESULT E_FAIL</code> error when trying to access a method in an AS3 .swf file, running as an AxShockwaveFlashObject component inside a Winform. The flash component can communicate with C# through Externalinterface just fine, but sendin from C# to Flash has been impossible so far.</p> <p>The error seems to be generic and meaningless, as I've found lots of unanswered questions. I will try nevertheless for this specific scenario:</p> <p><strong>C#</strong></p> <pre><code>String method = "&lt;invoke name=\"NewFilename\" returntype=\"xml\"&gt;&lt;/invoke&gt;&lt;arguments&gt;&lt;/arguments&gt;"; mainFlashControl.CallFunction(method); </code></pre> <p><strong>AS3</strong></p> <pre><code>public function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); if (ExternalInterface.available) { ExternalInterface.addCallback("NewFilename", NewFilename); } } public function NewFilename():void { // Do Something... } </code></pre> <p>UPDATE: All I've <a href="http://forums.adobe.com/message/84670?tstart=0#84670" rel="nofollow">been able to find</a> is a workaround that checks every time interval for any function waiting to be called, by making a call (from AS3 to C#) and reading the response. However, I also can't get the response to return anything. I've used <code>flashComponent.setResponseValue("test");</code> and on the flash side the Externalinterface.Call() always returns null.</p> <p>UPDATE: I've also looked into FSCommand now, also works form AS3 to C# but there doesn't seem to be any way for me to attach a return value to it either...</p>

    2. COyes. (Through a small hack: after the addCallback, within the if statement, I printed some text on the screen and it appeared)

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.
