DateTimePicker unable to select and modify a specific field

[Davider]

The result I need is similar to the following C# code. How can I achieve the same effect in QM?
 

Code:

using System;
using System.Globalization;
using System.Windows.Forms;

void Main()
{
    DateTimePicker dateTimePicker = new DateTimePicker();
    dateTimePicker.Format = DateTimePickerFormat.Custom;
    dateTimePicker.ShowUpDown = true;
    dateTimePicker.CustomFormat = "yy-M-dd HH:mm";

    DateTime initialDateTime = DateTime.Now.AddMonths(1).AddHours(1);
    dateTimePicker.Value = initialDateTime;

    dateTimePicker.ValueChanged += (sender, e) => Console.WriteLine(dateTimePicker.Value);

    using (Form form = new Form())
    {
        form.Controls.Add(dateTimePicker);

        Application.Run(form);
    }
}

    // Set the date and time format
    SendMessage(dtPicker, DTM_SETFORMAT, 0, (LPARAM)L"yy-M-dd HH:mm");

    // Get the current date and time, and increment the hour and month by 1
    SYSTEMTIME initialDateTime;
    GetLocalTime(&initialDateTime);
    initialDateTime.wHour += 1;
    initialDateTime.wMonth += 1;

    // Set the date and time
    SendMessage(dtPicker, DTM_SETSYSTEMTIME, GDT_VALID, (LPARAM)&initialDateTime);

    // Show the window
    ShowWindow(hwnd, nCmdShow);
    UpdateWindow(hwnd);

    // Message loop
    MSG msg;
    while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return (int)msg.wParam;
}

The above C# code was generated using ChatGPT and appears to be very understandable. However, the dialog window I have created is in QM (Quick Macros), and I need the QM code.
