Remarks
The ADO Fields object is a collection of ADO Field objects that pertain to this object. Each Field object holds a name/value pair defining some header field for the body part. The name is always a string, and the value is a VARIANT. The subtype of the VARIANT depends on the schema definition for the name. See the appropriate schema fields section of the reference for a list of valid fields to use, along with a list of the VARIANT subtypes for each field.
The fields that resize in this collection depend upon the specific implementation. Consult the appropriate Component Object Model (COM) class for details about available fields.
Note
When you use the ADO Fields.Update method, field values are updated only in memory. You must call the Save Method to save the changes to the Exchange store. To get the IDataSource interface, use the GetInterface method on the Collaboration Data Objects (CDO) object. This code is shown in the following example.
Example
Dim myAppt As New Appointment
Dim Flds As ADODB.Fields
Set Flds = myAppt.Fields
With Flds
.Item("xxx") = "zzz"
.Update
End With
'Save the fields to the Exchange store
Dim iDsrc As CDO.IDataSource
Set iDsrc = myAppt.GetInterface("IDataSource")
iDsrc.Save
