#include <CkJsonObject.h>

void ChilkatSample(void)
    {
    CkString strOut;

    // Note: This example requires Chilkat v9.5.0.63 or later.
    CkJsonObject json;

    bool success = json.LoadFile("qa_data/json/qb_accounts.json");

    // A sample of the content of qb_accounts.json is shown at the bottom of this example.
    // The idea of FindRecordString is to search for a record matching one field,
    // and then return the value of another field.

    // For example, we want to find the "Id" for the record where Name = Advertising

    const char *arrayPath = "QueryResponse.Account";
    const char *relativePath = "Name";
    const char *value = "Advertising";
    bool caseSensitive = true;
    const char *retRelPath = "Id";

    const char *id = json.findRecordString(arrayPath,relativePath,value,caseSensitive,retRelPath);
    if (json.get_LastMethodSuccess() != true) {
        strOut.append("Record not found.");
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    // The Id should be 7.
    strOut.append("The Id of the Advertising account is ");
    strOut.append(id);
    strOut.append("\r\n");
