Question

It seems that VB6 can’t correctly compare dates in some situations. Are there any solutions to this?

Private Sub CheckDate()

    date1 = #7/6/2010 2:00:00 PM#
    Debug.Print "Date 1: " + CStr(date1)

    date2 = DateAdd("h", -8, #7/6/2010 10:00:00 PM#)
    Debug.Print "Date 2: " + CStr(date2)

    Debug.Print "Equal? " + CStr(date1 = date2)

End Sub

The correct output should be:

Date 1: 7/6/2010 2:00:00 PM
Date 2: 7/6/2010 2:00:00 PM
Equal? True

but the real output is:

Date 1: 7/6/2010 2:00:00 PM
Date 2: 7/6/2010 2:00:00 PM
Equal? False

Is there any way around this, or is there any way to avoid this situation (whatever it is)?

Answer 1

You should use the DateDiff function. It can be adapted to whatever level of precision you need.
