Hi All
I have used Allen Browne's code (see http://allenbrowne.com/ser-16.html, bottom of page) as a model for my user-defined type and public function in an events management database.
Using the function in forms/VBA works fine.
But my DB crashes whenever I try to use it in a query.
My modules code:
= = =
Option Compare Database
Public Type EvCheks
EvType As String
EvAttCat As String
EvUnitAss As String
EvCheksAll As String
End Type
= =
Public Function getEvCheks(EV, EvUnit) as EvCheks
'Event Type: Event or DL
If (DLookup("evtype", "tblevents", "[evid] = " & EV)) = "Event" Then
getEvCheks.EvType = "Y"
Else: getEvCheks.EvType = "N"
End If
'Event Attendance Category: INDB= in database or LIST
If (DLookup("evattcat", "tblevents", "[evid] = " & EV)) = "INDB" Then
getEvCheks.EvAttCat = "Y"
Else: getEvCheks.EvAttCat = "N"
End If
'Event Assessing Organisation
Dim AOROName As String
Dim AOName As String
AOROName = DLookup("evunitassessable", "tblevunits", "[evunitid] = " & EvUnit)
AOName = Mid([AOROName], 1, InStr([AOROName], "/") - 1)
Select Case AOName
Case "NA"
getEvCheks.EvUnitAss = "N"
Case "ABCD"
getEvCheks.EvUnitAss = "Y"
Case Else
getEvCheks.EvUnitAss = "X"
End Select
getEvCheks.EvCheksAll = getEvCheks.EvType & getEvCheks.EvAttCat & getEvCheks.EvUnitAss
End Function
====
On a form, I have a button with on-click event code that defines the EV and EVU variables and displays a message box
MsgBox getEvCheks(EV, EVU).EvCheksAll
This works fine.
=====
In a query I have this SQL code:
SELECT tblEvUnits.EvId, tblEvUnits.EvUnitID, getevcheks([evid],[evunitid]) AS EventDetails
FROM tblEvUnits;
This causes the db to crash.
I cannot get the "back-end" definition of the function into the query, as Access rejects it because of the dot, i.e. ".EvCheksAll".
I suspect there is some formatting quirk for using a public function that includes a user-defined type, in a query.
Any/all assistance much appreciated.
