VB获取鼠标在当前窗体的坐标

采用窗体的MouseMove事件来获取鼠标坐标是可以的。如下我在文本框中显示当前鼠标的坐标程序，鼠标移动，坐标自动更新，只需要一个文本框控件，代码如下：Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)

Text1.Text = "当前鼠标坐标为，X：" X "Y:" Y

End Sub

vb.net 怎样获取鼠标单击点的坐标

通过窗体的MouseDown事件的e.X和e.Y属性获取。通过e.Location属性获取Point类型的坐标。

下面的代码示例使用 Location 属性跟踪鼠标左键单击，并绘制一系列直线段作为对用户输入的响应。如果隐藏窗体然后重新显示它，此示例不保留已绘制的线段，该代码为简单起见而被省略了。

Dim FirstPoint As Point

Dim HaveFirstPoint As Boolean = False

Sub Form1_MouseDownDrawing(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown

If HaveFirstPoint Then

Dim g As Graphics = Me.CreateGraphics()

g.DrawLine(Pens.Black, FirstPoint, e.Location)

HaveFirstPoint = False

Else

FirstPoint = e.Location

HaveFirstPoint = True

End If

End Sub

VB.NET想用GetWindowRECT获取某窗口的坐标，但测试结果是L,T,R,B显示都是0,0,0,0

很简单，原因有二。第一，VB里long是32位，但是VB.NET里是64位，Dim ksWND As Integer才对。第二，VB在API里默认传址，而VB.NET默认传值，所以API里要添加Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long,添加"ByRef" lpRect As RECT) As Integer

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long

Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long,byref lpRect As RECT) As Integer

Private Structure RECT

Dim Left As Integer

Dim Top As Integer

Dim Right As Integer

Dim Bottom As Integer

End Structure

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Dim ksWND As integer

Dim ksTitle As String

Dim winS As RECT

If TextBox1.Text "" Then

ksTitle = TextBox1.Text

ksWND = FindWindow(vbNullString, ksTitle)

GetWindowRect(ksWND, winS)

MsgBox("左上角坐标(" winS.Left "," winS.Top ")" vbCrLf "右下角坐标(" winS.Right "," winS.Bottom ")" vbCrLf "窗口高" winS.Bottom - winS.Top "窗口宽" winS.Right - winS.Left)

Else

MsgBox("请填写窗口名称")

End If

End Sub

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！！！！！！
