最完善的方法当然做键盘勾子
简单点的,就在Form的KeyDown属性里做就OK了
也要把窗口的keypreview设为True,然后粘贴下面的代码:
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
if keycode=vbkeyf3 then check1.value=check1.value xor 1
End Sub
就一句
自己做个试验就行了：
Public Class Form1
' 在窗体上放个 Label1
Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Lable1.Text = "KeyCode= " e.KeyCode.ToString vbCrLf
Lable1.Text = "KeyData= " e.KeyData.ToString vbCrLf
Lable1.Text = "KeyValue= " e.KeyValue.ToString
End Sub
End Class
运行起来，自己按键盘试试就知道了。
Public Class Form2
Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
AddHandler Label1.MouseEnter, AddressOf LabelMouseEnter
AddHandler Label2.MouseEnter, AddressOf LabelMouseEnter
AddHandler Label1.MouseLeave, AddressOf LabelMouseLeave
AddHandler Label2.MouseLeave, AddressOf LabelMouseLeave
AddHandler Label1.MouseDown, AddressOf LabelMouseDown
AddHandler Label2.MouseDown, AddressOf LabelMouseDown
End Sub
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
