#include <CkJsonObject.h>

void ChilkatSample(void)
    {
    CkString strOut;

    // This example requires Chilkat v9.5.0.63 or greater.

    CkJsonObject json;
    json.put_EmitCompact(false);

    // The UpdateString method updates or adds a string member.
    // It also auto-creates the objects and/or arrays that
    // are missing.  For example:
    json.UpdateString("test.abc[0].xyz","Chicago Cubs");

    // The JSON now contains:
    strOut.append(json.emit());
    strOut.append("\r\n");

    // {
    //   "test": {
    //     "abc": [
    //       {
    //         "xyz": "Chicago Cubs"
    //       }
    //     ]
    //   }

    json.UpdateString("test.abc[0].xyz","Chicago Cubs are going to win the World Series!");
    strOut.append(json.emit());
    strOut.append("\r\n");

    // {
    //   "test": {
    //     "abc": [
    //       {
    //         "xyz": "Chicago Cubs are going to win the World Series!"
    //       }
    //     ]
    //   }


    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
