Forms

If the logical size of the form is set to be larger than the physical size, scroll bars are automatically added as needed. All controls are placed according to the logical size of the form. This means that controls can be scrolled out of view.

If you set this property to infinite, scroll bars are not included. You can change this property at runtime by using the LOGHEIGHT Function (Form).

The LogHeight property is not supported in the RoleTailored client. The size and position of controls and pages are determined automatically, depending on the display device used.
