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

Text1.Text = Text1.Text + ";"

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
