Important Notice
The pages on this site contain documentation for very old MS-DOS software,

If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.
Height, Width Properties Details

{[form.][ctlname.] | SCREEN.}Height[ = height%]
{[form.][ctlname.] | SCREEN.}Width[ = width%]
Usage Notes
■ Height and Width values are always expressed in terms of characters.
■ For a form or control, the values for these properties change as the
object is sized by the user or by code.
■ A Height or Width setting less than 0 is an error. If Height or Width
is changed to less than MinHeight or MinWidth, but greater than 0, the
change is accepted, but ignored. For example, setting the Height of a
resizable form to 1 sets Height to 4 (MinHeight); subsequent reads of
the Height property will list 4.
■ Changing the number of displayable lines on screen may cause a form to
be resized. For example, when all forms are invisible or hidden, the
Height property of a form with Height greater than NewScreenHeight will
change to the new ScreenHeight value when the form is made visible
again.
■ By default, the values of the Height and Width properties at run time
are equivalent to the height and width of the object at design time.
■ For forms and the SCREEN object, maximum Height and Width properties
depend on the screen display characteristics of your computer.
See: ◄Screen Mode Summary►
■ The height and width of a control can range from 1 to an absolute
maximum of 254. If moving a control causes Height or Width to exceed
254, the move attempt is ignored. If resizing a control causes Width
to exceed 254, the maximum relative value within the 254 absolute range
is used.
■ Use Height and Width and their related properties, Left and Top, for
operations or calculations based on an object's total area, such as
sizing or moving the object. See: ◄Left Property► ◄Top Property►
■ Use the ScaleHeight and ScaleWidth properties for operations or
calculations based only on an object's internal area, such as printing
or moving objects within a form or picture box.
