KISS ! ( keep it simple & stupid )

Thank you for this very useful article. Do you have idea, how can I extend this to give back a return value at AS->C# call ?
Because now AS->C# is a simple procedure, not a function call and in a lot case return value is needed…

This is my first interaction with flex.
Can i use flex to carry out memory dump of flash application without using ShockwaveFlash COM object?

Thanks.

public function send(command : String, message : String):void
{
ExternalInterface.call(command, message);
}

and in c#

switch (command)
{
case “sendText” : doSometing(); break;
case “Some_Other_Command” : doSometingElse(); break;
case ….
…..
}

csharp.as
——————–
package
{
import flash.external.ExternalInterface;

public class Csharp
{
private var _text : TextArea;

public function Csharp(someTextArea : TextArea)
{
this._text = someTextArea;
ExternalInterface.addCallback(“addText”,addText);
}

// get message from c#
private function addText(val:String):void
{
_text.appendText(val + “\n”);
}

// Send message to C#
public function send(message : String):void
{
ExternalInterface.call(“sendText”, message);
}
}
}

the way to use it is

var com : Csharp = new Csharp(responseBox); // where responseBox is a textarea where messages will be apended when recived from c#

and if you want to send someting you do
com.send(‘hello from flash’);

that’s it. the code was in the article, rest of it was just…interface
