System.Windows.Forms.SendKeys for controlling content over Adobe Flash Player

Hello,

I'm trying to control a some content presented over Adobe Flash Player in a browser.

This manipulation works well when I'm performing myself on keyboard the keys UP, DOWN, LEFT, RIGHT.

But when I try to issue these commands through System.Windows.Forms.SendKeys it doesn't work over Flash content. If I run my program over any other content or program to test it I can see that it is working, I mean it sends the input correctly!

Does anyone have a suggestion why it doesn't work over Adobe Flash Player?

I had already tried:

Send

System.Windows.Forms.SendKeys.Send("{RIGHT}");

Send and wait

System.Windows.Forms.SendKeys.SendWait("{RIGHT}");

Perform a click over the content before issuing the commands, like:

                            //Mouse left down
                            mouse_event(0x00000002, 0, 0, 0, 0);

                            //Release mouse left button
                            mouse_event(0x00000004, 0, 0, 0, 0);

                            System.Windows.Forms.SendKeys.Send("{RIGHT}");

Or even instead of using RIGHT arrow, perform a similar operation with the mouse (pressing left button, move and release left button)

                            //Mouse left down
                            mouse_event(0x00000002, 0, 0, 0, 0);

                            //Move right
                            mouse_event(0x00000001, 40, 0, 0, 0);

                            //Release mouse left button
                            mouse_event(0x00000004, 0, 0, 0, 0);

But still no results.

Just to reaffirm all of these tries works well over other programs or content and also if I reproduce them with a mouse or keyboard over Flash content it also works. How can I make my program be able to also do it?

Thanks for your attention.
