To print
PDF417 barcode in VC++ application, you need Barcodesoft BCSPDF417 true type font and cruflbcs.dll .
If you download and install the demo of Barcodesoft
PDF417 software on your computer,
you will find crUFLBCS.dll from
"C:\Program Files (x86)\Common Files\Barcodesoft\Fontutil\" folder.
If you don't find cruflbcs.dll on your computer, please download it from
PDF417 Barcode VC++ .
crUFLBCS.dll is a COM object with IPDF417 interface.
You can find detailed information about IPDF417 interface from readme.html.
To call the methods of IPDF417 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.
Late Binding
Your codes to create
PDF417 barcode run slower than using Early Binding.
However, your codes are version-independent as long as COM interface and method parameters remain unchanged.
Early Binding
Your codes to create
pdf417 barcode in VC++ application run faster than using Late Binding.
1. Import type library. Don't forget to call
CoInitialize() before using COM interface.
2. If you want to use T2OLE macro to convert LPTSTR into LPOLESTR, you need to call USES_CONVERSION macro first.
3. You may either call Encode method or EncodeCR method to encode PDF417 barcode with options.
#include <atlbase.h>
Use MFC to Generate Wrapper Class
If you use VC++ 6 to generate
PDF417 barcode , press Ctrl + W to start Class Wizard. Then click "Add Class" button, choose "From a type library".
Choose crUFLBCS.dll, then select all Interfaces you want to add wrappers and click OK.
If you use Visual Studio 2003 or above to create
PDF417 barcode ,
1. On the Project menu, select Add Class.
2. Select MFC Class from Typelib from the list of templates.
3. For Add Class from, select Registry.
4. In the list of available type libraries, find crUFLBCS.
5. From the list of interfaces in that type library, select all classes for which you want to add wrappers.
6. Click Finish.
Please don't forget to call OleInitialize(NULL) before using the following code snippet to generate
PDF417 barcode .
CString strOutput;
