'23/02/2011 12:34:56' is not valid date and time

Question

In my code I am facing a problem. Example code:

var 
    d1: tdatetime
begin
    d1 := strtodatetime(\'23/02/2011 12:34:56\');
end; 

but it

Answer 1

the StrToDateTime function uses the ShortDateFormat and DateSeparator to convert the date part and the LongTimeFormat and TimeSeparator to the time part. so you string must match with theses variables to convert the string to TDateTime. instead you can use the StrToDateTime with the TFormatSettings parameter, to parse you string.

 function StrToDateTime(const S: string; const FormatSettings: TFormatSettings): TDateTime; 

check this sample

Var
StrDate : string;
Fmt     : TFormatSettings;
dt      : TDateTime;
begin
fmt.ShortDateFormat:='dd/mm/yyyy';
fmt.DateSeparator  :='/';
fmt.LongTimeFormat :='hh:nn:ss';
fmt.TimeSeparator  :=':';
StrDate:='23/02/2011 12:34:56';
dt:=StrToDateTime(StrDate,Fmt);
