vb.net获取鼠标位置 vbs实现鼠标点击
VB.net 我的程序只有一个窗体,窗体很小,怎么才能检测到鼠标在窗体以外的范围移动,还有键盘输入
用API GetCursorPos

用Timer隔一段时间获取一次鼠标位置。
键盘输入,用 GetKeyboardState
加点分的话就给你完整的代码
Public Class NativeMethods
'获取鼠标位置
Declare Function GetCursorPos Lib "user32.dll" _
(ByRef lpPoint As System.Drawing.Point) as boolean
Private Shared keyState() As Byte
DllImport("user32.dll") _
Private Shared Function GetKeyboardState(ByVal keyState() As Byte) As Boolean
End Function
Private Shared Sub Update()
keyState = New Byte(256) {}
Dim result As Boolean = GetKeyboardState(keyState)
' Check for error:
If result = False Then
Debug.WriteLine("GetKeyBoardState error: " Marshal.GetLastWin32Error)
Throw New Exception("GetKeyBoardState error: " Marshal.GetLastWin32Error)
End If
End Sub
Public Enum LightState
Off
[On]
End Enum
' Example - the keyboard lights...
Public Shared ReadOnly Property CapsLockState() As LightState
Get
Update()
Dim isOn As Boolean = (keyState(Keys.CapsLock) = 1)
Return IIf(isOn, LightState.On, LightState.Off)
End Get
End Property
Public Shared ReadOnly Property NumLockState() As LightState
Get
Update()
Dim isOn As Boolean = (keyState(Keys.NumLock) = 1)
Return IIf(isOn, LightState.On, LightState.Off)
End Get
End Property
Public Shared ReadOnly Property ScrollLockState() As LightState
Get
Update()
Dim isOn As Boolean = (keyState(Keys.Scroll) = 1)
Return IIf(isOn, LightState.On, LightState.Off)
End Get
End Property
End Class
pinvoke.net: GetCursorPos (user32)
pinvoke.net: GetKeyboardState (user32)
在VB.net中怎么获取 鼠标在屏幕中的坐标
Private Declare Function GetCursorPos Lib "user32" (ByRef lpPoint As POINTAPI) As Long '全屏坐标声明
Private Declare Function ScreenToClient Lib "user32.dll" (ByVal hwnd As Int32, ByRef lpPoint As POINTAPI) As Int32 '窗口坐标声明
Private Structure POINTAPI '声明坐标变量
Public x As Int32 '声明坐标变量为32位
Public y As Int32 '声明坐标变量为32位
End Structure
'以上是声明部分
'以下是窗口部分
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick '用时钟控件来取坐标,窗口上放个Timer组件,Enabled为允许,周期为10到100毫秒均可
Dim P As POINTAPI '声明坐标变量
Dim xx, yy '声明转换要用到的变量
GetCursorPos(P) '获取鼠标在屏幕中的位置
ScreenToClient(Me.Handle.ToInt32, P) '转换为本窗体的坐标
xx = P.x.ToString '把X转换成能显示到文本框的字符串格式
yy = P.y.ToString '把Y转换成能显示到文本框的字符串格式
TextBox1.Text = xx + "和" + yy '文本框的内容为X坐标和Y坐标
End Sub
用VB.NET写一个获取鼠标当前屏幕的坐标.
你好 那因为你放在了Label1控件的移动事件了 。
说明:
当前你的代码是在当鼠标经过Label1的MouseMove事件才被激活,其他事件不备激活的。
建议应用函数调用具体方法网上应该有
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
TextBox1.Text = System.Windows.Forms.Cursor.Position.X.ToString "," System.Windows.Forms.Cursor.Position.Y.ToString
End Sub
上面代码我是做过测试才发的,完全能实现你的要求!!!!!!
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:
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
