StrToDate function

Declaration

function StrToDate(const S: ShortString): TDateTime

Description

StrToDate converts the string S to a TDateTime date value. The Date must consist of 1 to three digits, separated by the DateSeparator character. If two numbers are given, they are supposed to form the day and month of the current year. If only one number is given, it is supposed to represent the day of the current month. (This is not supported in Delphi)

The order of the digits (y/m/d, m/d/y, d/m/y) is determined from the ShortDateFormat variable.

Errors

On error (e.g. an invalid date or invalid character), an EConvertError exception is raised.
