Desktop capture

[Chirieac]

Hello!

I want to capture the desktop on every 300 milliseconds.
Is a faster way than with BitBlt function?

Ex: When capturing, the windows, when they are moved, are moving slow (now they are in one place and then in another place: they don't move smhootley).

I also realised that the mouse cursor is not captured. Why?
How can I make him to be captured?

Thanks.

I've read something about "video hook kernel-mode driver". What is that? Is it possible to capture desktop faster with that?

What about directX? Can I capture the desktop faster with directX? Is it possible?

Please help me, please!
