'运行此程序需要再窗体添加控件Timer
Option Explicit
Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long
Private Declare Function ScreenToClient Lib "user32" (ByVal hwnd As Long, lpPoint As POINTAPI) As Long
Private Type POINTAPI
x As Long
y As Long
End Type

Private Sub Form_Load()
Timer1.Interval = 10 '设置获取鼠标坐标间隔
End Sub

Private Sub Timer1_Timer()
Dim P As POINTAPI
GetCursorPos P '获取鼠标在屏幕中的位置
ScreenToClient Me.hwnd, P '转换为本窗体的坐标
Dim t As Boolean
t = P.x >= 0 And P.y >= 0 And P.x < Me.Width / Screen.TwipsPerPixelX And P.y <= Me.Height / Screen.TwipsPerPixelY
If t Then Me.Caption = "x=" & P.x & "y=" & P.y '按像素显示坐标
'If t Then Me.Caption = "x=" & P.x * Screen.TwipsPerPixelX & "y=" & P.y * Screen.TwipsPerPixelY '按缇显示坐标
