2D-Barcode Property pages

Active 2D-Barcode Component  may be inserted into Container programs (such as WordPad) generally by selecting Insert Object from the EDIT or INSERT menus and choosing A2barcode Control from the list of options presented.

The properties of the barcode image may be set by selecting the barcode and either double-clicking on it, or by summoning its Property Pages dialog from the Edit – A2barcode Control Object menu item.

The Property Pages dialog provides a tabbed dialog box containing four pages.

The Data page contains a text version of the data being supplied to the component to create the barcode.

If the data contains non-printable (or non-Windows) characters, then the display may be rather strange. Such data will normally be passed in via programming rather than by using the Data window.

The General Page provides the user with the opportunity to set the Codetype, the Code value (the Caption), and the target height and width. Checkboxes are provided to allow the Nominal size to be specified (valid only for barcodes which have a nominal size), and for the check digit to be calculated automatically (for those codes which have check digits. An X unit box allows the width of the barcode to be calculated by the control, using the X unit size The X unit is the width of the thinnest bar (in mils – 0.001 inches, not mm). If X is provided as 0 then the width of the barcode is determined by the content of the width box.

Details of the properties are given in the Reference section.

The Appearance page enables most of the remaining properties to be specified, either through checkboxes, by entering a border size in the edit box, or selecting a colour by pushing the foreground or background colour change button.

 

 

 

Each Property page contains an OK button which, if pushed causes the current contents of all the pages to be used in re-creating the barcode image. The pages also contain a Cancel button that may be used to close the Property pages dialog and discard any changes made.
