[SOLVED] TCalendar Change?

[Pascaluvr]

I have just got another PC - previously I had Windows XP, but on my new PC I have Win7.

My application uses TCalender to select a date of records to examine.  On XP CalDayChanged returns dd/mm/yyyy in Cal.date but after recompiling under Win7, Cal.Date returns dd-Mmm-yyyy (as in 29-Feb-2012).   Am I missing something here or is this a compatibility issue with 'write once - compile anywhere'?

afair, there's bug in fpc which does not read properly locales on win7, so it assumes defaults OR check your locale settings for dates in cpl.

Thank you for your prompt reply... and while I thought I was reasonably computer savy...   I have no idea what this means:

"OR check your locale settings for dates in cpl."

cpl?????

Thanks again

cpl = Control Panel/Regional Settings

Thanks for that.  Strangely, there is no setting for the XP response.  What is worse, is that if I give my program to someone else, they have to change the settings on their computer to suit my needs,,, and possibly screw up other programs!

Surely 'Write once  - compile anywhere' doesn't come with fine print for common functions.

Don't get me wrong... Laz/FPC are great products and I'm not criticizing... but for compatibility surely the Lazarus function should return the same, regardless of cpl settings?

You can try this:

procedure TForm1.CalChange(Sender: TObject);
begin
  Edit1.Text:= FormatDateTime('dd/mm/yyyy',Cal.DateTime);
end;

or in FormCreate set:

Code: [Select]

ShortDateFormat:='dd-mm-yyyy';

or in FormCreate set:

Code: [Select]

ShortDateFormat:='dd-mm-yyyy';

Thank you = that was the problem.  I hadn't set the date format in Control Panel.  I will also add this code so that my program will run on someone else's computer.
