Class Property (All CDO Library Objects)

Class Property (All CDO Library Objects)

The Class property returns the object class of the object. Read-only.

Syntax

object.Class

Data Type

Long

Remarks

The Class property contains a numeric constant that identifies the CDO Library object. The following values are defined:

CDO also defines CdoUnknown, with the value –1, for an object implementing the OLE IUnknown interface.

The Class property does not correspond to a MAPI property and cannot be rendered into HTML hypertext by the CDO Rendering Library.

Example

' Function: Util_DecodeObjectClass
' Purpose: Decode the long integer class value,
'          show the related object name
' See documentation topic: Class property
Function Util_DecodeObjectClass(lClass As Long)
' error handling here ...
Select Case (lClass)
    Case CdoSession:
        MsgBox ("Session object; Class = " & lClass)
    Case CdoMsg:
        MsgBox ("Message object; Class = " & lClass)
End Select
' error handling ...
End Function

' Function: TestDrv_Util_DecodeObjectClass
' Purpose: Call the utility function DecodeObjectClass for Class values
' See documentation topic: Class property
Function TestDrv_Util_DecodeObjectClass()
' error handling here ...
If objSession Is Nothing Then
    MsgBox "Need to set the Session object: Session->Logon"
    Exit Function
End If
' expect type CdoSession = 0 for Session object
Util_DecodeObjectClass (objSession.Class)
Set objMessages = objSession.Inbox.Messages
Set objOneMsg = objMessages.GetFirst
If objOneMsg Is Nothing Then
    MsgBox "Inbox is empty"
    Exit Function
End If
' expect type CdoMessage = 3 for Message object
Util_DecodeObjectClass (objOneMsg.Class)
' error handling here ...
End Function
