关于光标位置解决思路

关于光标位置
form中有10多个textbox，如何判断光标在哪个textbox上啊？代码怎么写？

[解决办法]

VB.NET code

#Region ""    <DllImport("user32.dll", CharSet:=CharSet.Auto, CallingConvention:=CallingConvention.Winapi)> _    Friend Shared Function GetFocus() As IntPtr    End Function    ''' <summary>    ''' 获得当前获得焦点的控件    ''' </summary>    ''' <returns></returns>    Private Function GetControl() As Control        Dim fsControl As Control = Nothing        Dim fshandle As IntPtr = GetFocus()        If fshandle <> IntPtr.Zero Then            fsControl = Control.FromHandle(fshandle)        End If        Return fsControl    End Function    Private Sub Form1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseClick        Me.Text = "当前焦点控件名称:" + GetControl.Name    End Sub#End Region
[解决办法]
Me.ActiveControl.Name
