Examples

The following code example demonstrates the Top property of the Button control. The example adds two Button controls named sizeButton and locationButton to a document. When sizeButton is clicked, the Height and Width properties are adjusted so that the button changes size. When locationButton is clicked, the Top and Left properties are adjusted so that the button changes location. After each button is modified, the example displays the new Right, Bottom, Height, Width, Top and Left property values of the clicked button in a message box.

This example is for a document-level customization.
