    {
    CkString strOut;

    // Imagine we have two separate JSON objects.
    CkJsonObject jsonA;
    jsonA.UpdateString("animal","zebra");
    jsonA.UpdateString("colors[0]","white");
    jsonA.UpdateString("colors[1]","black");

    jsonA.put_EmitCompact(false);
    strOut.append(jsonA.emit());
    strOut.append("\r\n");

    // jsonA contains:

    // {
    //   "animal": "zebra",
    //   "colors": [
    //     "white",
    //     "black"
    //   ]
    // }

    CkJsonObject jsonB;
    jsonB.UpdateString("type","mammal");
    jsonB.UpdateBool("carnivore",false);

    jsonB.put_EmitCompact(false);
    strOut.append(jsonB.emit());
    strOut.append("\r\n");

    // jsonB contains:

    // {
    //   "type": "mammal",
    //   "carnivore": false
    // }

    // Let's say we want to insert jsonB into jsonA to get this:

    // {
    //   "animal": "zebra",
    //   "info" " {
    //       "type": "mammal",
    //       "carnivore": false
    // 	},
    //   "colors": [
    //     "white",
    //     "black"
    //   ]
    // }

    // First add an empty object at the desired location:
    jsonA.AddObjectAt(1,"info");

    // Get the JSON object at that location, and load the JSON..
    CkJsonObject *jsonInfo = jsonA.ObjectOf("info");
    jsonInfo->Load(jsonB.emit());
    delete jsonInfo;

    strOut.append(jsonA.emit());
    strOut.append("\r\n");

    // The end result is this:

    // {
    //   "animal": "zebra",
    //   "info": {
    //     "type": "mammal",
    //     "carnivore": false
    //   },
    //   "colors": [
    //     "white",
    //     "black"
    //   ]
    // }


    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
