The dFont Component may be operated entirely by setting or retrieving Property values programmatically.
Clicking on the dFont Component in the panel under the form when Visual Studio's Properties box is displayed will show the current settings for component's available properties. Most of these may be edited using the Properties box, or may have their values set from within the user's program by statements of the kind
Dfont1.Caption="12345" Visual Basic
Dfont1.Caption="1234"; C#
Dfont1.set_Caption("1234"); J#
dFont Component properties that are set AFTER a barcode has been created may be retrieved within user's programs by statements of the kind:
x=Dfont1.Error Visual Basic
x=Dfont1.Error; C#
x=Dfont1.get_Error() J#
