Data Members

wVk

The virtual-key code of the key to simulate pressing or releasing. If dwFlags contains the KEYEVENTF_UNICODE tag, this must be 0.

wScan

If dwFlags contains the KEYEVENTF_UNICODE flag, this specifies the hardware scan code of the Unicode character key to simulate pressing or releasing. If that flag is not used, this must be 0.

dwFlags

A combination of the following flags specifying what kind of keyboard input to synthesize:

KEYEVENTF_EXTENDEDKEY

Prefix the scan code with a prefix byte having the value &HE0.

KEYEVENTF_KEYUP

The key specified in bVk is being released. If this flag is not specified, the key is being pressed.

KEYEVENTF_UNICODE

Windows 2000: Use a Unicode character key generated by a non-keyboard hardware input which is imitating keyboard input.

time

The time stamp of the keyboard input event, in milliseconds. If 0, the system creates a time stamp by default.

dwExtraInfo

An additional 32-bit value associated with the keyboard event.

Constant Definitions

Const KEYEVENTF_EXTENDEDKEY = &H1
Const KEYEVENTF_KEYUP = &H2
Const KEYEVENTF_UNICODE = &H4
