// personalize -- C++ port of examples\Vb6\personalize\personalize.bas

#include <cstdio>

// The Delphi original draws DateTimeToStr(Date + Time), which renders with the
// SYSTEM short-date + long-time patterns -- "02-08-2026 5:55:02 PM" here. A
// plain strftime layout is not an equivalent: dropping the AM/PM designator
// changes the number of whitespace-separated tokens on the page, and that word
// count is exactly what tools/compare_lang_outputs.py diffs, so the row read
// CONTENT_DIFF for a reason that had nothing to do with the engine. Read the
// same two locale values Delphi reads (LOCALE_SSHORTDATE / LOCALE_STIMEFORMAT,
// which is what GetDateFormat(DATE_SHORTDATE) / GetTimeFormat(0) expand).
//
// Declared by hand rather than via <windows.h>: lumaspdf.h rolls its own Win32
// types, and including the real SDK headers after it breaks wincrypt.h with
// ~100 syntax errors. Same reason print_pdf.cpp hand-declares its print dialog.
