step 1 install clearimage sdk download and install the clearimage sdk step 2 configure your project use visual studio c++ clearimage example project https //barcode reader inliteresearch com/get ci example cpp or follow the instruction below when using the example project, copy clearimage dll clearimage dll in the executable folder or in the path in your visual studio c++ project include a copy of c \program files (x86)\inlite\clearimagesdk\clearimage wrapper hpp c \program files (x86)\inlite\clearimagesdk\clearimage wrapper hpp in every source file that uses clearimage api add a copy of c \program files (x86)\inlite\clearimagesdk\clearimage lib c \program files (x86)\inlite\clearimagesdk\clearimage lib to your project's properties >linker >input >additional dependencies properties >linker >input >additional dependencies entry place clearimage dll clearimage dll in a location where it can be found according to microsoft's dll search order rules typically it is a working folder where your application started from the clearimage dll clearimage dll is installed in 32 bit version from c \program files (x86)\inlite\clearimagesdk\win32\clearimage dll c \program files (x86)\inlite\clearimagesdk\win32\clearimage dll 64 bit version from c \program files (x86)\inlite\clearimagesdk\x64\clearimage dll c \program files (x86)\inlite\clearimagesdk\x64\clearimage dll this code demonstrates the use of clearimage dll api runtime errors are reported in exceptionci exceptionci object \#include "clearimage wrapper hpp" void main() { try { 	 ciserver server = createciserver();

	} barcode reading read 1d barcodes from a page this example reads code 39 and code 128 barcodes set barcode types used in your application setting reader >autodetect1d=true; reader >autodetect1d=true;
