Unmatched record and msgbox

[Daryl2106]

Hi,

I was wondering how you write the vba for msgbox to say "No records match the Student ID entered" when a query is opened from a form button. That is if the query can't find a record to match the data in an unbound text box.Thanks in advance.

Take care,

Daryl

I presume you mean an Access query object. Why open a query object?

If you open a query object then have to do a search of the query with domain aggregate function (such as DLookup or DCount). Why not just do a search of the table with code in the button event?

The code associated with the button is simply Me.Requery. If there is no mtch for the ID in the query criteria (as entered on a forum) then no records are returned. I need to let the user know that they have entered and invalide ID.

So you are not opening a query, just filtering a form?

Why not help the user make a valid selection? This can be managed with a LimitToList combobox or a listbox.

Don't let the requery take place if there is not a valid entry. The code can do a lookup on data.

If IsNull(DLookup("ID", "tablename", "ID=" & Me.ID)) Then
MsgBox "Invalid ID. Try again."
Me.tbxID.SetFocus
Else
Me.Requery
End If
