Controls
See Table 7.
DialogResult

FormBorderStyle
Gets or sets a System.Windows.Forms.FormBorderStyle enumeration value that indicates whether the form can be resized by the user and how the graphics of the frame border appear and function.
Icon
Gets or sets the object reference to a System.Drawing.Icon class instance that represents the icon displayed for the form on the taskbar and also the icon for the control box enabled by the ControlBox property.
Location
Gets or sets a System.Drawing.Point structure that specifies the pixel screen coordinates of the upper-left-hand corner of a form.
MainMenuStrip
Gets or sets the object reference to a System.Windows.Forms.MenuStrip class instance that represents the primary menu container for the form.
MaximizeBox
Gets or sets an ABL LOGICAL value indicating whether the Maximize button is displayed in the title bar of the form.
MinimizeBox
Gets or sets an ABL LOGICAL value indicating whether the Minimize button is displayed in the title bar of the form.
Modal
Gets an ABL LOGICAL value indicating if the form is displayed modally (as a dialog box).
Owner
Gets or sets the form that owns this form. OpenEdge also allows .NET forms to own ABL windows and for ABL windows to own .NET forms using the ABL PARENT attribute. For more information, see Using.NET Forms with ABL Windows.
Size
Gets or sets a System.Drawing.Size structure that specifies the width and height of the form in pixels.
Text
Gets or sets an ABL CHARACTER value that represents the title displayed in the title (caption) bar of the form.
Visible
Gets or sets an ABL LOGICAL value that indicates whether the form is visible or can be displayed on the screen. The form Show( ) method also sets this property to TRUE. You do not always need to initialize this property to TRUE in order to initially display the form, depending on how you block for input on the form. For more information, see ABL support for managing .NET forms and controls.
Other common properties for controls might also apply to forms. For more information, see Table 7.
