hi,I want to call the api function clipcursor to fix mouse in the region on a picturebox. But it has no effction. I don't know why it is.My code is following:
Private Type RECT
left As Long
top As Long
right As Long
bottom As Long
End Type

Private Declare Function ClipCursor Lib "user32" (lpRect As RECT) As Long
Private Sub Form_Load()
Picture1.Scale (-10, 10)-(10, -10)
D.left = -8: D.top = 8: D.right = 8: D.bottom = -8
End Sub

Private Sub Picture1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
dim t as long
t = ClipCursor(D)
End Sub

Please give me guide about it. Thanks a lot.
