Fields Property (Message Object)

Exchange Server 2003

Topic Last Modified: 2004-06-09

The Fields property returns a single Field object or a Fields collection object. Read-only.

objMessage.Fields

objMessage.Fields(index)

objMessage.Fields(proptag)

objMessage.Fields(name)

index

Integer. Value must be greater than 0 and less than or equal to 65,535 (&HFFFF). Specifies the index within the Fields collection.

proptag

Long. Value must be greater than or equal to 65,536 (&H10000). Specifies the property tag value for the MAPI property to be retrieved.

name

String. Specifies the name of the custom MAPI property.

Object (Field or Fields collection)

The Fields property returns one or all of the fields associated with a Message object. Each field typically corresponds to a MAPI property. Data types are preserved, except that MAPI counted binary properties are converted to and from character strings representing hexadecimal digits.

The Fields property provides a generic access mechanism that allows Microsoft® Visual Basic® and Microsoft® Visual C++® programmers to retrieve the value of a MAPI property using either its name or its MAPI property tag. For access with the property tag, use objMessage.Fields(proptag), where proptag is the 32-bit MAPI property tag associated with the property, such as CdoPR_PRIORITY. To access a named property, use objMessage.Fields(name), where name is a string that represents the custom property name.

Although the Fields property itself is read-only, the collection it returns can be accessed in the normal manner through its Add and Delete methods, and the properties on its member Field objects retain their respective read/write or read-only accessibility.

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

' get the messages Fields collection
Set objFieldsColl = objOneMsg.Fields
' get the first field of the Fields collection of the message
i = 1
Set objOneField = objFieldsColl.Item(i)
' could also be objFieldsColl(i) since Item is default property
If objOneField Is Nothing Then
    MsgBox "error; cannot get this Field object"
Else
    MsgBox "Selected Field " & i
End If
