Specifies whether to display the left and right guard characters (start character and stop character).
property ShowGuards: Boolean;
For TBarcode1D_Code39, TBarcode1D_Code39Ext, TBarcode1D_UPU, TBarcode1D_PZN, and TBarcode1D_Code32 barcode components, the property specifies whether to display the left and right guard characters (start character and stop character). If the property is set to true, the start and stop characters are shown as an asterisk (*) in the human readable text. If the property is set to false then the start and stop characters are not represented in human readable text. Note, you don't have to specify the start and stop characters to the Barcode or Data (only for Delphi/C++ Builder 2009 or later) property even if they are displayed in the human readable text.
