The keybd_event function synthesizes a keystroke. The system can use such a synthesized keystroke to generate a WM_KEYUP or WM_KEYDOWN message. The keyboard driver’s interrupt handler calls the keybd_event function.
Windows NT only: This function has been superseded. Use SendInput instead.
VOID keybd_event(
BYTE bVk, |
// virtual-key code |
BYTE bScan, |
// hardware scan code |
DWORD dwFlags, |
// flags specifying various function options |
DWORD dwExtraInfo |
// additional data associated with keystroke |
); |
Value |
Meaning |
KEYEVENTF_EXTENDEDKEY |
If specified, the scan code was preceded by a prefix byte having the value 0xE0 (224). |
KEYEVENTF_KEYUP |
If specified, the key is being released. If not specified, the key is being depressed. |
This function has no return value.
Although keybd_event passes an OEM-dependent hardware scan code to Windows, applications should not use the scan code. Windows converts scan codes to virtual-key codes internally and clears the up/down bit in the scan code before passing it to applications.
An application can simulate a press of the PRINTSCREEN key in order to obtain a screen snapshot and save it to the Windows clipboard. To do this, call keybd_event with the bVk parameter set to VK_SNAPSHOT, and the bScan parameter set to 0 for a snapshot of the full screen or set bScan to 1 for a snapshot of the active window.
