ACC: Combo Boxes Limited to 65536 (64K) Rows

• Microsoft Access versions 2.0, 7.0, 97

SYMPTOMS

Novice: Requires knowledge of the user interface on single-user computers.

When you view the list portion of a combo box or list box that is based on a table or query with more than 65536 records, you see only the first 65536 rows.

CAUSE

Microsoft Access limits the number of rows displayed in a combo box or list box to 65536 rows.

RESOLUTION

Use a query to restrict the number of rows the combo box or list box is displaying to no more than 65536.

STATUS

This behavior is by design.

         Sub FillTable()
            ' Creates a table that contains
            ' 70,000 records.
   
            Dim db As Database
            Dim tbl As TableDef
            Dim fld As Field
            Dim rs As Recordset
            Dim lng As Long
   
            Set db = CurrentDb
            Set tbl = db.CreateTableDef()
            tbl.Name = "LargeTable"
            Set fld = tbl.CreateField("Field1", dbLong)
            tbl.Fields.Append fld
            db.TableDefs.Append tbl
            Set rs = tbl.OpenRecordset(dbOpenDynaset)
            For lng = 1 To 70000
               rs.AddNew
               rs!Field1 = lng
               rs.Update
            Next
            rs.Close
            MsgBox "Table Created"
