Demonstrate Binary Data Encoding Methods

Demonstrates binary data encoding methods.

Note: This example requires Chilkat v9.5.0.64 or later.

Unicode C++

#include <CkBinDataW.h>
#include <CkStringBuilderW.h>

    //  The 1st byte is at index 0.

    offset = 2;
    numBytes = 4;
    binData.RemoveChunk(offset,numBytes);
    //  The bytes remaining are 00,01,06,07,08,and 09
    wprintf(L"after removing chunk: %s\n",binData.getEncoded(L"hex"));
