I have a function:



function DateToXMLStr(aDateTime: TDateTime): string;
var
 d : Char;
begin
  d:= DateSeparator;
  DateSeparator:= XML_DATE_SEPARATOR;

  if aDateTime = 0 then
  begin
    Result:= ''
  end else
  begin
    Result := FormatDateTime(XML_DATE_FORMAT,aDateTime);
  end;
  DateSeparator:= D;  
end;



To get the Date on a proper format in my xml.

How can i do the reverse?  Unformat it back to a TDateTime?

maybe something like (not tested):

function XMLStrToDate(aDateTime: string): TDateTime;
var
 d : Char;
begin
  d:= DateSeparator;
  DateSeparator:= XML_DATE_SEPARATOR;

  if aDateTime = '' then
  begin
    Result:= 0
  end else
  begin
    DateTimeToString( Result, XML_DATE_FORMAT, aDateTime);
  end;
  DateSeparator:= D;  
end;

you will have to do it manually by getting the rigth parst from your string in XML_DATE_FORMAT and using EncodeDateTime()
If you tell me what XML_DATE_FORMAT is I'll make you a start.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I think I was to early to Grade this:

DateTomeToString looks like:


IE IT expect a String not a TDateTime as the first parameter:

I solved it by:
var
 FS : TFormatSettings;
 LCID : Integer;
begin
  LCID:= GetUserDefaultLCID;
  GetLocaleFormatSettings(LCID,FS);
  FS.DateSeparator:= XML_DATE_SEPARATOR;
  FS.ShortDateFormat:= XML_DATE_FORMAT;
  Result:= StrToDateTime(aDateTimeString,FS)

>IE IT expect a String not a TDateTime as the first parameter:

of course it does: you did ask for the reverse, did you not? reverse of
function DateToXMLStr(aDateTime: TDateTime): string;
is
function XMLStrToDate(aDateTime: string): TDateTime;

so I don't see where the problem is. StrToDateTime also takes a string as first parameter.
