    // Load the contents of the filePath
    CkStringBuilderW sbIncludeFile;

    // Replace the first occurrence of #include <...> line with the contents of the include file.
    sbSrc.ReplaceAllBetween(L"#include",L">",sbIncludeFile.getAsString(),true);

    wprintf(L"%s\n",sbSrc.getAsString());

    // sbSrce now contains:
    // 	1
    // 	2
    // 	3
    // 	Hello World!
