Controlling Form Behavior

When you are designing a form in the Form Designer, the form is live: except for setting the Visible property to false (.F.), visual and behavioral changes you make are immediately reflected in the form. If you set the WindowState property to 1 – Minimized or 2 – Maximized, the form in the Form Designer immediately reflects this setting. If you set the Movable property to false (.F.), a user will not be able to move the form at run time and you won't be able to move the form at design time either. You might want to design the functionality of your form and add all the appropriate controls before you set some of the properties that determine form behavior.

The following form properties are commonly set at design time to define the appearance and behavior of the form.

Property
