expression A variable that represents a CheckBox object.
The BorderWidth property uses the following settings.
|Hairline||0||(Default) The narrowest border possible on your system.|
|1 pt to 6 pt||1 to 6||The width as indicated in points.|
You can set the default for this property by using the control's default control style or the DefaultControl property in Visual Basic.
To use the BorderWidth property, the SpecialEffect property must be set to Flat or Shadowed and the BorderStyle property must not be set to Transparent. If the SpecialEffect property is set to any other value and/or the BorderStyle property is set to Transparent, and you set the BorderWidth property, the SpecialEffect property is automatically reset to Flat and the BorderStyle property is automatically reset to Solid.
The exact border width depends on your computer and printer. On some systems, the hairline and 1-point widths appear the same.
