Re: [MS_AccessPros] If IsNull(OptionDate)

Kevin-

Is OptionDate a control on the current form? If so, you should be using Me. Also, it's better to use VBA If rather than call the function - like this:

If IsNull(Me.OptionDate) Then

strRpt = "rptHotelBookingAskOption"

strPrefix = "Asking for Option for group: "

Else

strRpt = "rptHotelBookingExtendOption"

strPrefix = "Asking for Extending the Option for the group: "

End If

If OptionDate is truly a date/time value, then it will be Null when "blank" or has no value.

It seems that IsNull won't work for date type.

I am using this in vb:

On Error GoTo ErrHandle

Dim strRpt As String
Dim strPrefix As String
Dim strEmailAddress As String
Dim strSubject As String

strRpt = IIf(IsNull(OptionDate),"rptHotelBookingAskOption","rptHotelBookingExtendOption")

strPrefix = IIf(IsNull(OptionDate),"Asking for Option for group: ","Asking for Extending the Option for group: ")

strEmailAddress = ELookup("HotelContactEmail", "tblHotelContact", "HotelID=" & Me.HotelID, "RecentContact ASC")

strSubject = strPrefix & "-" & IIf(IsNull(HotelBookingCode), Me.Parent.GroupCode & "-" & HotelBookingID, Me.Parent.GroupCode & "-" & _
HotelBookingID & " (Reference: " & HotelBookingCode & ")") & " From " & ELookup("CompanyEnglishName", "tblCompany", "CompanyID=" & 1)

    If vbYes = MsgBox("Click Yes to send. " & _
        " Click No to edit.", vbQuestion + vbYesNo + vbDefaultButton2) Then

    DoCmd.OpenReport strRpt, acViewPreview, , "HotelBookingID = " & Me.HotelBookingID, acHidden
    SendReportHTML strRpt, strEmailAddress, strSubject, "Send", ""
    DoCmd.Close acReport, strRpt, acSaveNo

    Else
    DoCmd.OpenReport strRpt, acViewPreview, , "HotelBookingID = " & Me.HotelBookingID, acHidden
    SendReportHTML strRpt, strEmailAddress, strSubject, "Display", ""
    DoCmd.Close acReport, strRpt, acSaveNo

    End If

ErrExit:
    Exit Sub

ErrHandle:
    Resume ErrExit

Best Regards,

Kevin

Kevin-

Where are you using this - in a query?

Only obvious thing is to put brackets around the field name:

IIf(IsNull([OptionDate]),"rptHotelBookingAskOption","rptHotelBookingExtendOption")

Dear All,
Please check this code: IIf(IsNull(OptionDate),"rptHotelBookingAskOption","rptHotelBookingExtendOption")
My problem is: if OptionDate is null, the the result won't be "rptHotelBookingAskOption". What's wrong with this code? Thanks.
Best Regards,
Kevin
