INPUT Structure

The INPUT structure is used by SendInput to store information for synthesizing input events such as keystrokes, mouse movement, and mouse clicks.

Syntax

复制代码typedef struct tagINPUT { DWORD type; union {MOUSEINPUT mi; KEYBDINPUT ki; HARDWAREINPUT hi; }; }INPUT, *PINPUT;

typedef struct tagINPUT {
DWORD type;
union {MOUSEINPUT mi;
KEYBDINPUT ki;
HARDWAREINPUT hi;
};
}INPUT, *PINPUT;

Members

type
Specifies the type of the input event. This member can be one of the following values.
INPUT_MOUSE
The event is a mouse event. Use the mi structure of the union.
INPUT_KEYBOARD
The event is a keyboard event. Use the ki structure of the union.
INPUT_HARDWARE
Windows 95/98/Me: The event is from input hardware other than a keyboard or mouse. Use the hi structure of the union.

mi
A MOUSEINPUT structure that contains information about a simulated mouse event.
ki
A KEYBDINPUT structure that contains information about a simulated keyboard event.
hi
Windows 95/98/Me: A HARDWAREINPUT structure that contains information about a simulated event from input hardware other than a keyboard or mouse.

Remarks

This structure contains information identical to that used in the parameter list of the keybd_event or mouse_event function.

Windows 2000/XP: INPUT_KEYBOARD supports nonkeyboard input methods, such as handwriting recognition or voice recognition, as if it were text input by using the KEYEVENTF_UNICODE flag. For more information, see the remarks section of KEYBDINPUT.
