Res = MaDate.VersChaîne("Le numéro du jour JJ du mois n° MM de l'année AAAA")
MaDate = DateSys()
Res = MaDate.VersChaîne(maskDateSystem) 
// Res utilise le format défini dans le projet

MaDate is Date
MaDate = "20031202"
// La casse des jours et mois en lettres est dépendante des options linguistiques du projet 
Res = MaDate.VersChaîne("JJJ JJ MMM AAAA")

Remarks

Validity of the date

The validity of the date passed as parameter is checked. A message is displayed if the date is invalid. You can check the validity of a date using DateValid. The date storage format allows you to store dates from 01/01/0001 to 12/31/9999.

WLanguage functions and WLanguage properties make accurate calculations on dates from January 1st, 1583.

Date format

<Date type>.ToString is used to format a date returned by IntegerToDate or DateSys. The result can be assigned to a text control, for example.

To get the date in another format, use <ANSI string>.Right, Left, Middle, etc.

Special case: parameter <Format> not specified

The language options specified for dates in the project description are used if no specific format is defined.

To view the project language options:

Open the project description: On the "Project" tab, in the "Project" group, click "Description".
Select the "Languages" tab.

For example:

if the project uses the language options of Windows for the dates, the days of the week and the months will start with an Uppercase character on a computer running Windows in English.
if the project uses specific parameters for the dates for one or more languages (custom name of the day or month, etc.), these parameters will be taken into account for the specified language.
