Microsoft Access VBA Macro Programming

Weekday

TheWeekdayfunction returns an integer between 1 (Sunday) and 7 (Saturday) that

represents the day of the week for a date expression:

Weekday (dateexpression)

MsgBox WeekDay("6-Mar-2003")

This will return the value 5, which is Thursday.

This function can be useful if you want a date to always default to a particular day of the

week. For example, if you always want a date to show the week ending Friday for the current

week, you could use the following formula:

MsgBox Now - WeekDay(Now) + 6

TheWeekdayfunction starts from Sunday, so it reducesNowback to the last Sunday and

then adds 6 to get to Friday. You can also use it to calculate the number of working days

between two dates:

For n = DateValue("1-Jan-03") To DateValue(" 18 -Jan-03")

If Weekday(n) <> 1 Or Weekday(n) <> 7 Then

WorkDay = WorkDay + 1

End If

Next n

MsgBox WorkDay

WorkDaywill return the value of 13, which is the number of working days between the two

dates.

The SendKeys Command

TheSendKeyscommand is not really a function but rather a command statement. A command

statement like this can be used in a function or a subroutine. It allows you to command another

application by sending keypresses to it, exactly the same as if you were typing at the keyboard

into that application. It effectively simulates keypresses on the keyboard and can be used for

low-level automation of programs that do not support OLE automation.
