يه راه ساده اش اينه كه البته نياز به هندل شئ داريم كه شئ Image هندل نداره. ولي مثلاً براي picture يا خود Form به اين صورت:
Private Declare Function SendMessage Lib "User32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Declare Sub ReleaseCapture Lib "User32" ()
Private Const WM_NCLBUTTONDOWN = &HA1
Private Const HTCAPTION = 2
Private Sub Picture1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 1 Then
ReleaseCapture
SendMessage Picture1.hWnd, WM_NCLBUTTONDOWN, HTCAPTION, 0&
End If
End Sub
