1.3 KEYBOARD & MOUSE package CXKEYBOARD & CXMOUSE
[http://blog.9cbs.net/mythma]
1, what is Keyboard & Mouse
"well known by all people". DX9 provides interface idirectInputDevice8.
2, the function of both
Keyboard: Read keyboard button information
MOUSE: Read the button, location information, set the cursor property (such as using the picture).
3, use process
Create IDirectInput8 Object DirectInput8CREATE
Create IDirectInput8 devices (keyboard, mouse, etc.) CreateDevice
Set device properties setcooperativeelevel
SetDataFormat
Get equipment use rights acquire
Read the data incoming data getDeviceState
Release equipment and IDirectinput8 Release
Set the mouse cursor process:
Create Cursor Image Resources: Refer to Surfaces
Set the cursor as specified picture setCursorproperties
Set the initial position of the cursor setCursorPosition
Show cursor showcursor

CXMOUSURFACE package
In order to make the cursor of the animation effect, a SURFCES list is required, so it inherits a CXMOUSESURFACE class from cxsurface so that multiple pictures can be operated.
