The GetNext method returns the next object in the specified collection. It returns Nothing if no next object exists, for example, if already positioned at the end of the collection.
Note To ensure correct operation of the GetFirst, GetLast, GetNext, and GetPrevious methods in a large collection, call GetFirst before calling GetNext on that collection, and call GetLast before calling GetPrevious. To ensure that you are always making the calls on the same collection, create an explicit variable that refers to that collection before entering the loop.
expression.GetNext
expression Required. An expression that returns one of the objects in the Applies To list.
Example
The following Visual Basic for Applications example searches the subfolders of Inbox for a folder called MyPersonalEmails and displays a message to the user. If you do not have a subfolder called MyPersonalEmails in your Inbox folder, the example will display nothing.
Sub TestGetNext()
Dim outApp As New Outlook.Application
Dim nsp As Outlook.NameSpace
Dim mpf As Outlook.MAPIFolder
Dim mpfSubFolder As Outlook.MAPIFolder
Dim flds As Outlook.Folders
Dim idx As Integer
Set nsp = outApp.GetNamespace("MAPI")
Set mpf = nsp.GetDefaultFolder(olFolderInbox)
Set flds = mpf.Folders
Set mpfSubFolder = flds.GetFirst
Do While Not mpfSubFolder Is Nothing
If mpfSubFolder.Name = "MyPersonalEmails" Then
MsgBox "The folder was found."
Exit Do
End If
Set mpfSubFolder = flds.GetNext
Loop
End Sub
