For combo boxes, field groups, and the SESSION handle, this attribute is read-only.
In character mode, the HEIGHT-PIXELS attribute must be set before the browse is realized. Attempting to set the attribute after realization of the browse causes a run-time error.
For control-frames, the HEIGHT-PIXELS attribute maps to the Height property of the control-frame COM object (ActiveX control container).
For browses, the HEIGHT-PIXELS attribute sets the decimal height, in pixels, of the browse without changing the height of the browse's rows. If you change the value of a browse's HEIGHT-CHARS or HEIGHT-PIXELS attribute, the number of rows that appear in the viewport might change.
