For forms, the Height measurement does not include the borders and title bar. Also, if the ScrollBars Property is set to enable scroll bars, Height does not include space taken up by the scroll bar when it appears. In Visual FoxPro, the maximum height of a form has been increased to approximately 32,000 pixels.
For controls, the height is measured from the outside of the control's border.
The value for this property changes as the object is sized by the user or by code.
Use the Height and Width properties for calculations based on an object's total area.
 Note: |
|---|
| The Height property is read-only when it applies to a control contained in a Column object. |
Example
The following example demonstrates how the Height property is used specify the height of three command buttons on a form.
The AddObject method is used to add a Line control and three command buttons to a form. The Height property specifies the vertical height of each command button.
