This property returns and sets the distance between the internal top edge of an object and the top edge of its container.
object.Top [= value]
For a control, the Top property is always measured in units derived from the coordinate system of its container. The values for Top change as the object is moved by a user or by code.
You can specify a single-precision number for the Top property.
Use the Left, Top, Height, and Width properties for operations based on an object's external dimensions, such as moving or resizing.
