Sending keystrokes to a Flash/Silverlight app embedded in a webbrowser control (mostly done)

NOTE: This doesn't seem to necessarily apply to Silverlight only, I've read people have the same problems with Flash, so keep that in mind.

I'm trying to write a program that will control Netflix through my own buttons (for now, eventually it will be extended to a mobile remote control app), by sending hotkeys directly to it using the windows api.

• I am able to retrieve the actual window handle used by the Netflix Silverlight player.
• I am able to send keystrokes to specified window handles (using the TranslateMessage function in win api)
• But I cannot, for some reason, get the netflix player to recognize any keystroke I send.
• I have tried using the SetFocus function in the win api before attempting to send keypresses and that doesn't help.

What I need to figure out, is why it's differentiating keys sent via api calls, from physical keyboard key presses.

Here's how I have things set up (window class names for reference):

Form1 (开发者_如何转开发WindowsForms10.Window.8.app.0.33c0d9d)

WebBrowser Control (Shell DocObject View)

HTML Page (Internet Explorer_Server)

Embedded Silverlight player (MicrosoftSilverlight)

I was wondering if someone might be able to offer some suggestions. Thanks very much in advance.. hopefully someone can help get me through this.

I tried to send KeyEvents to a flash application in C# (I wanted to 'hack' the griefing game called "CLOP").

I noticed this didn't work. I can however perfectly send KeyEvents to the browser itself but the flash plugin seems to ignore these even after acquiring focus.

I suspect this isn't possible because of security measures.

I found the following thread here on StackOverflow that explained a bit more about this (this one is about flash as well) Send keyboard and mouse events to Flash Movie
