Very simple way to move a form holding down mouse button
Just paste this into your form code window. No API call is needed.
Press F5 & hold down mouse key & move it. The Form will move with the mouse also.
Dim pastx, pasty, presentx, presenty, bt As Long
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
pastx = X
pasty = Y
End Sub
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
presentx = X
presenty = Y
bt = Button
End Sub
Function moving()
xx = presentx - pastx
yy = presenty - pasty
If bt Then 'set your condition: left btn or right btn or mid btn
Me.Left = Me.Left + xx
Me.Top = Me.Top + yy
End If
End Function

Actually, I didn't know about the below API before I coded that. It was long time ago when I started my programming in VB6. You can also move form using these APIs.
But using the above code, the below APIs are no longer needed.

Thanks to all.
