mouse event Xbutton

[Zexor]

I want to capture a xbutton mouse click on a webbrowser and an AxWindowsMediaPlayer. But neither of those seems to see the xbutton press. For the webbrowser i have added a handler for mousedown with HtmlElementEventHandler but Xbutton doesnt seem to trigger it. And the MediaPlayer AxWMPLib._WMPOCXEvents_MouseUpEvent doesnt have xbutton either.
Is there a way to capture the Xbutton1 and 2 presses for those controls?

i figure out how to do the xbuttons. Is there a way to capture the mouse wheel's left right click? I think thats the left and right scroll buttons. I just need to capture it on any control or window.

No one knows how to capture the mousewheel horizontal scroll event?
