how to write an event for shockWave flash object

Is there any way to write click event for shockW开发者_如何学Goave flash object?

AFAIK there is no way of doing this without modifing the flash application (swf) or at least wrapping it in a new one. Once you are able to capture the click event in Flash, you can use any of the communication schemes available for flash+a host application. You could use in this scenario:

-FS Command ("Sending Data from a Flash Movie to the Hosting C# Application" in CodeProject)
-External Interface ("Fun with C# and the Flash Player 8 External API" also in CodeProject)

How about this:

Derive your Form from this class, and insert this code in your derived class

protected override void onShockWaveClick()
    {
        MessageBox.Show("Is this it?\n In Main Form", "AxSHockWave Message");
    }
    protected override void onShockWaveBorderLineMouseMove(int x, int y)
    {
        if (y >= axShockwaveFlash1.Height - 20)
        {
            Text = "Borderline x=" + x.ToString() + " , y = " + y.ToString() + ", ht= " + axShockwaveFlash1.Height;
        }
        else
        {
            Text = "Moving x=" + x.ToString() + " , y = " + y.ToString() + ", ht= " + axShockwaveFlash1.Height;
        }
    }

everything else will be taken care by the base class
