回答1:

Declare Sub keybd_event Lib "user32" Alias "keybd_event" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long) 这个是API函数.
参数:
bVk ------------ Byte,欲模拟的虚拟键码

bScan ---------- Byte,键的OEM扫描码

dwFlags -------- Long,零;或设为下述两个标志之一
KEYEVENTF_EXTENDEDKEY
指出是一个扩展键,而且在前面冠以0xE0代码
KEYEVENTF_KEYUP
模拟松开一个键

dwExtraInfo ---- Long,通常不用的一个值。api函数GetMessageExtraInfo可取得这个值。允许使用的值取决于特定的驱动程序

案例:
keybd_event vbKeyTab, 0, 0, 0
