A date value for which you want the name of the day |
String. Returns a string whose value is the weekday (Sunday, Monday, and so on) of date. If date is null, DayName returns null.
DayName returns a name in the language of the runtime files available on the machine where the application is run. If you have installed localized runtime files in the development environment or on a user’s machine, then on that machine the name returned by DayName is in the language of the localized files.
These statements evaluate the date literal 1993-07-04 and set day_name to Sunday:
string day_name
day_name = DayName(1993-07-04)
These statements check to be sure the date in sle_date is valid, and if so set day_name to the day in sle_date:
string day_name
IF IsDate(sle_date.Text) THEN
day_name = DayName(Date(sle_date.Text))
ELSE
MessageBox("Error", &
"This date is invalid: " &
+ sle_date.Text)
END IF
