Display multiple validation messages to the user

Question

In MS-Access, how can I store the rows retrieved from my SELECT statement in an array, and show many rows in one messagebox:

Dim rSEL, rSUM, rDes As DAO.Reco         


        

Answer 1

I would not use a Message Box for this, since you could potentially have hundreds of rows, and they wouldn't all fit. Instead, I would create a custom form with a ListBox, and whenever you get the error, do the following:

If vQnty > vSum Then
    <ErrorForm>.<ListBox>.AddItem("You have only (" & vSum & " ) of Item (" & vDes & " ) in the stock")
    Cancel = True
End If

If at the end of the loop, Cancel = True, display ErrorForm.

Another thing - you may be able to create a query which does all this in one go. You need to join the three tables, and add the vQnty > vSum condition. This would be pretty neat, because you could use the query as the source of the ListBox - no code required.

Anyway have you known GetRows method in both DAO and ADO? You may use it in your case.

yourarray = recordset.GetRows()
