its underlying data source. It is set and used in three situations : one when the property is not set for the underlying field; second when the format setting of the underlying field is to be overridden; third when a control, which is not bound to any underlying data field, is to be displayed in a particular manner. Decimal Places : This property specifies the number of decimal places up to which the control should display a numeric data. It must be used in conjunction with format property to determine the final appearance of numeric data.
Caption : The caption property applies to label, command button and toggle buttons. This property is used to specify what printed matter will appear on the face of the control. In the context of label control, the printed matter is made to appear using this caption property. Visible : This property specifies whether the control embedded on the Form should be visible or hidden when the Form is opened.
The property can make a control appear conditionally when required. Layout Properties ( Left, Top, Width, Height ) : These properties are used to set the position and size of the control. Back Colour and Style : The back colour property specifies background colour, as opposed to text colour, for the control. This property, when set to transparent, shows the form’s background colour through the control.
The setting is preferred for an Option group. Special effects : This property provides the three dimensional effect to a control in its appearance. The options for this property are: Flat, Raised, Sunken, Etched, Shadowed and Chiseled. Each of these effects give a different look to the control.
Border Properties (style, colour, and effect): The Border properties are capable of affecting the style, colour and thickness of the Border of a control. The Border style options are Transparent, Solid, Dashes, Dots, etc. The Border colour property specifies the colour of the Border and it is possible to select from a variety of colours. The Border width property can be set to one of several point sizes.
