vb.net记录键盘 vb键盘按键代码( 三 )


Private Sub LabelMouseEnter(ByVal sender As Object, ByVal e As System.EventArgs)
Dim c As Label = DirectCast(sender, Label)
c.BackColor = Color.DodgerBlue
End Sub
Private Sub LabelMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)
Dim c As Label = DirectCast(sender, Label)
Form1.TextBox1.Text = c.Text
End Sub
Private Sub LabelMouseLeave(ByVal sender As Object, ByVal e As System.EventArgs)
Dim c As Label = DirectCast(sender, Label)
c.BackColor = SystemColors.Control
End Sub
End Class
在VB.NET中如何实现键盘上两个键长按!在线等~~长按你可以用计时器来实现啊,写个例子:
Private blCtrl As Boolean = False
Private Sub Form1_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown
If e.KeyCode = Keys.LControlKey Then blCtrl = True
End Sub
Private Sub Form1_KeyUp(sender As Object, e As KeyEventArgs) Handles Me.KeyUp
If e.KeyCode = Keys.LControlKey Then blCtrl = False
End Sub
然后你可以在计时器里检测blCtrl的状态来确定,不知道你的具体情况是什么样的
总之是用一个布尔变量来记录按键状态,配合计时器来达到你想要的功能
在vb.net 键盘事件 中 如何获取当前鼠标的位置 。比如我按下“enter”键,获取此时刻鼠标的位置 。控件中keyup属性记录键盘操作
比如vb.net记录键盘:
Private Sub from1_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyUp
if e.keycode = keys.Enter then
lable1.text =Cursor.Position.X
lable2.text = Cursor.Position.Y
end if
end sub
