ComboBox.Recordset Property

  • Article
Access Developer Reference

Returns or sets the ADO Recordset or DAO Recordset object representing the record source for the specified object. Read/write Object.

Syntax

expression.Recordset

expression   A variable that represents a ComboBox object.

Remarks

The Recordset property returns the recordset object that provides the data being browsed in a form, report, list box control, or combo box control. If a form is based on a query, for example, referring to the Recordset property is the equivalent of cloning a Recordset object by using the same query. However, unlike using the RecordsetClone property, changing which record is current in the recordset returned by the form's Recordset property also sets the current record of the form.

The read/write behavior of the Recordset property is determined by the type of recordset (ADO or DAO) and the type of data (Access or SQL) contained in the recordset identified by the property.

Recordset type Based on SQL data Based on data stored by the Access database engine
ADO Read/Write Read/Write
DAO N/A Read/Write

The following example opens a form, opens a recordset, and then binds the form to the recordset by setting the form's Recordset property to the newly created Recordset object.

Visual Basic for Applications 
  Global rstSuppliers As ADODB.Recordset
Sub MakeRW()     
    DoCmd.OpenForm "Suppliers"
    Set rstSuppliers = New ADODB.Recordset
    rstSuppliers.CursorLocation = adUseClient
    rstSuppliers.Open "Select * From Suppliers", _
         CurrentProject.Connection, adOpenKeyset, adLockOptimistic     
    Set Forms("Suppliers").Recordset = rstSuppliers
End Sub

Use the Recordset property:

  • To use methods with the Recordset object that aren't directly supported on forms. For example, you can use the Recordset property with the ADO Find or DAO Find methods in a custom dialog for finding a record.
  • To wrap a transaction (which can be rolled back) around a set of edits that affect multiple forms.

Changing a form's Recordset property may also change the RecordSource, RecordsetType, and RecordLocks properties. Also, some data-related properties may be overridden, for example, the Filter, FilterOn, OrderBy, and OrderByOn properties.

Calling the Requery method of a form's recordset (for example, Forms(0).Recordset.Requery) can cause the form to become unbound. To refresh the data in a form bound to a recordset, set the RecordSource property of the form to itself (Forms(0).RecordSource = Forms(0).RecordSource).

  • To bind multiple forms to a common data set. This allows synchronization of multiple forms. For example,
Visual Basic for Applications 
     Set Me.Recordset = Forms!Form1.Recordset

When a form is bound to a recordset, an error occurs if you use the Filter by Form command.

Example

The following example uses the Recordset property to create a new copy of the Recordset object from the current form and then prints the names of the fields in the Debug window.

Visual Basic for Applications 
  Sub Print_Field_Names()
    Dim rst As DAO.Recordset, intI As Integer
    Dim fld As Field

Set rst = Me.<strong class="bterm">Recordset</strong>
For Each fld in rst.Fields
    ' Print field names.
    Debug.Print fld.Name
Next



End Sub

The next example uses the Recordset property and the Recordset object to synchronize a recordset with the form's current record. When a company name is selected from a combo box, the FindFirst method is used to locate the record for that company, causing the form to display the found record.

Visual Basic for Applications 
  Sub SupplierID_AfterUpdate()
    Dim rst As DAO.Recordset
    Dim strSearchName As String

Set rst = Me.<strong class="bterm">Recordset</strong>
strSearchName = CStr(Me!SupplierID)
rst.FindFirst "SupplierID = " &amp; strSearchName
If rst.NoMatch Then
    MsgBox "Record not found"
End If
rst.Close



End Sub

The following code helps to determine what type of recordset is returned by the Recordset property under different conditions.

Visual Basic for Applications 
  Sub CheckRSType()
    Dim rs as Object

Set rs=Forms(0).<strong class="bterm">Recordset</strong>
If TypeOf rs Is DAO.Recordset Then
    MsgBox "DAO Recordset"
ElseIf TypeOf rs is ADODB.Recordset Then
    MsgBox "ADO Recordset"
End If



End Sub
