if e.keycode = keys.Enter then

lable1.text =Cursor.Position.X

lable2.text = Cursor.Position.Y

end if

end sub

VB编写键盘记录器

键盘记录没有必要用全局钩子，如果用不好会严重影响系统的效率·VB有一个API函数可以很好的实现键盘记录代码如下：通用部分声明：Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer 'API函数的声明dim time as integer添加2个按钮,一个textbox控件。command1_click事件中添加：timer1.enable = truecommand1.enable = falsecommand2.enable = true command2_click :timer2.enable = falsecommand1.enable = truecommand2.enable = false form_load :

command1.enable = truecommand2.enable = false添加一个timer控件,interval属性设置为1000.Enable属性设置为false.并添加下面代码：time = time +1if time = "10" thentimer1.enable = falsecommand1.enable = truecommand2.enable = falseelseFor i = 32 To 256

x = GetAsyncKeyState(i)

If x = -32767 Then

Text1.Text = Text1.Text + Chr(i)

End If

x = GetAsyncKeyState(186)

If x = -32767 Then

Text1.Text = Text1.Text + ";"

End If

x = GetAsyncKeyState(187)

If x = -32767 Then

Text1.Text = Text1.Text + "="

End If

x = GetAsyncKeyState(188)

If x = -32767 Then

Text1.Text = Text1.Text + ","

End If

x = GetAsyncKeyState(189)

If x = -32767 Then

Text1.Text = Text1.Text + "-"

End If

x = GetAsyncKeyState(190)

If x = -32767 Then

上面的代码中command1为开启按纽,command2为关闭按钮，按下开启按钮后将记录10秒内的键盘消息并在text1中显示我没有在窗体上输出，应为如果消息太多了会显示不好如果你要在窗体输出就改用print函数输出吧

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
