Border
Border
Adds a 3D border to the button
Read-only This is a style property that is only available in the forms designer. It is possible to modify this programmatically through the Style property in the Create event.
Applies to: List Box , Picture Button
This design time style determines whether a picture control has a 3D effect border like a button or whether it is flat on the form. The former is appropriate if the control is to act like a button but the latter would be better if the control is just acting as a picture panel. The default is FALSE (for no border) but it can be set to TRUE in the Forms Designer.
In the case of listboxes it enables or disables the standard border for the control.
