Help on my little game
Author
I need some help on DirectInput. I just started a few days ago and I'm stuck. So, I uploaded the project file and I want someone to please look at it and find out what's wrong with it.

Thanks in advance,

I'm sorry, but my intrenetz doesn't allow me to download files from megaupload.com.
What exactly about DirectInput do you need help on?

Its about the mouse device pointer is NULL.
I uploaded it somewhere else: http://rapidshare.com/files/163690745/paddlegame.rar.html

I'm going to go out on a limb and guess that you might not be creating the mouse device before you're using it.
Did you follow any DirectInput tutorials?

Ok, here's where I narrowed it down to:
The code that is messed up on debug is this line:
I created the device and everything. And I am using a DirectX game programming book to learn.

I created the device and everything.
Then the mouse device pointer shouldn't be NULL.

Then refer to your book on how to use DirectInput.
Or, you could follow any of the DirectInput tutorials, and find the answers you're looking for.

I don't want you to debug my code, I have already done that -.- All that I want is someone to look at that code and see what is wrong with the device.

It's uninitialized/NULL, that's what's wrong with the mouse device pointer. Which would mean that the device hasn't been created.
