VB 程序检测按键

VB 程序检测按键
弹出所按下键(使用KeyDown事件)

语法格式为：
Sub Object_KeyDown(KeyCode As Integer，Shift As Integer)

例：

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer) If KeyCode = vbKeyUp Then     msgbox "您按了上键!"ElseIf KeyCode = vbKeyDown Then     msgbox "您按了下键!" ElseIf KeyCode = vbKeyLeft Then     msgbox "您按了左键!" ElseIf KeyCode = vbKeyRight Then     msgbox "您按了右键!" End If End Sub 

依此类推,可以设置为其键值
下面提供VB中的各个按键常量!
