Date Validation Rules

Date Validation Rules

Date Validation Rules

This may seem very basic, but I'm learning...Here's the question:

How do I code a validation rule at Table level or in VB to check if a date typed in by a user is either the 1st of the month or the 15th of the month?

Also how do I check what day it falls on?  Example: the 1st of January fall on a Saturday.

RE: Date Validation Rules

You should do this on the form, as they are entering data. Try this:

Put this code on the BeforeUpdate Event of your date field.
This is assuming your text field is named txtDate

Private Sub txtdate_BeforeUpdate(Cancel As Integer)
    Dim intDay As Integer
    intDay = DatePart("d", Me.txtdate)
    If intDay <> 1 And intDay <> 15 Then
        MsgBox "You must enter a date on the 1st of the 15th to continue"
        Cancel = True
    End If
End Sub
