To print Aztec Code in VC++ application, you need Barcodesoft BCSAztec true type font and cruflbcs.dll.
If you download and install the demo of Barcodesoft Aztec Code software on your computer, you will find crUFLBCS.dll from
"C:\Program Files\Common Files\Barcodesoft\Fontutil\" folder.
If you don't find cruflbcs.dll on your computer, please download it from Aztec Code VC++.
crUFLBCS.dll is a COM object with IAztec interface.
You can find detailed information about IAztec interface from readme.html.
To call the methods of IAztec interface from VC++, you can use either Late Binding or Early Binding.
Late binding is used when type information of an object is unavailable at compile time.
Early binding requires the client to get access to the type library before compile.
