Create a utility function to parse a date string in YYYY-MM-DD format into a FILETIME struct. This will be used for date filtering in later tickets. Test in main() with sample dates, converting and printing success/failure or verifying FILETIME values.
- Function signature:
bool StringToFileTime(const std::wstring& dateStr, FILETIME& fileTime) - Uses
swscanf_sfor parsing andSystemTimeToFileTimefor conversion. - Returns
falseon invalid format. - In
main(): Test valid and invalid date strings and print results.
#include <windows.h>
#include <iostream>
#include <string>
/**
* @brief Converts a date string in the format "YYYY-MM-DD" to a Windows FILETIME structure.
*
* This function takes a wide-character string representing a date in the format "YYYY-MM-DD"
* and attempts to parse it into year, month, and day components. It then converts these
* components into a SYSTEMTIME structure and subsequently into a FILETIME structure.
* The function returns true if the conversion is successful, or false if the input string
* is not in the correct format or the conversion fails.
*
* @param dateStr A wide-character string (std::wstring) containing the date in "YYYY-MM-DD" format.
* @param fileTime A reference to a FILETIME structure where the converted time will be stored.
* @return bool True if the conversion succeeds, false otherwise.
