No because Mouse.X and Mouse.Y are object relative positions.so belong to
the calling objects Drag event

See Drag.X and Drag.Y

Or use Mouse.ScreenX , Mouse.ScreenY with the dropped objects screen
positions.
Dim iDropRelativeMouseX = Mouse.ScreenX - MyDroppedControl.ScreenX
Dim iDropRelativeMouseY = Mouse.ScreenY - MyDroppedControl.ScreenY
