HOWTO: Move Messages Using Active Messaging MoveTo Method
ID: Q172740

The information in this article applies to:
- Collaboration Data Objects (CDO), version 1.1
- Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, version 5.0
- Microsoft Visual Basic Standard and Professional Editions, 32-bit only, for Windows, version 4.0
SUMMARY
Using the Active Messaging version 1.1 Object Library you can move a message to another folder without first copying and then deleting it. This new functionality is provided by the new MoveTo method.
This article describes how to use the MoveTo method.
MORE INFORMATION
The sample code in this article requires a reference to the Microsoft Active Messaging 1.1 Object Library (Olemsg32.dll). If you are missing this file, please see the following article in the Microsoft Knowledge Base:
Q171440 INFO: Where to Acquire the Collaboration Data Objects Libraries
This article requires that you set up the appropriate folders to move a message to. The sample code assumes that messages have a subject line starting with either "East" or "West".
The syntax of the MoveTo method is as follows:
Set objMovedMessage = objMessage.MoveTo(folderID [, storeID ] )
where
- objMovedMessage : On successful return, contains the moved Message object.
- objMessage : Required. This Message object.
- folderID : Required. String. The unique identifier of the destination Folder object in which this message is to appear.
- storeID : Optional. String. The unique identifier of the InfoStore object in which the message is to appear, if different from this current InfoStore.
The FolderID is a string created when a folder is created and it never changes. If you know the FolderID, you can directly code it into your application. If you do not know the FolderID, but know the folder name and where it is located, you can find the FolderID by using the ID property of the folder object. This example assumes that you do not know the FolderID, but that you do know the name of the folder you want to move a message to.
Sample Code
Copy the following code to a Module:
Option Explicit
Public objSession As MAPI.Session
Public strEast As String
Public strWest As String
Sub Main()
Dim objInboxFolder As Folder
Dim objInboxFolders As Folders
Dim f As Integer
Screen.MousePointer = vbHourglass
Set objSession = CreateObject("MAPI.Session")
objSession.Logon ("YourSessionIDHere")
Set objInboxFolder = objSession.Inbox
Set objInboxFolders = objInboxFolder.Folders
'Set strMoveToFolderID equal to the ID property of the
'folder you want to move the message to. This will
'be used later
With objInboxFolders
For f = 1 To .Count
Select Case .Item(f).Name
Case "East"
strEast = .Item(f).ID
Case "West"
strWest = .Item(f).ID
End Select
Next f
End With 'objInboxFolders
Load Form1
Form1.Show
Screen.MousePointer = vbNormal
End Sub Copy the following code to a Form:
Option Explicit
Private Sub cmdMoveMail_Click()
If Not MoveMessageToInboxSubfolder Then
MsgBox "A move operation failed"
End If
End Sub
Public Function MoveMessageToInboxSubfolder() As Boolean
Dim objInboxFolder As Folder
Dim objInMessages As Messages
Dim objOneMessage As Message
Dim objMoveMessage As Message
Dim objInboxFolders As Folders
Dim objMoveToFolder As Folder
Dim objMsgFilter As MessageFilter
Dim i As Integer 'Attachment Counter
Dim f As Integer 'Folder counter
Dim strMoveToFolderID As String
On Error GoTo ErrorHandler
Screen.MousePointer = vbHourglass
Set objInboxFolder = objSession.Inbox
Set objInboxFolders = objInboxFolder.Folders
Set objInMessages = objInboxFolder.Messages
Set objMsgFilter = objInMessages.Filter 'Set the Message Filter
'object
'Filter for unread messages
objMsgFilter.Unread = True
'Loop through all the messages in the objInMessages
For i = 1 To objInMessages.Count
Set objOneMessage = objInMessages.Item(i)
'Look for a subject that we want to move to another folder
Select Case Left(UCase(objOneMessage.Subject), 4)
Case "EAST"
strMoveToFolderID = strEast
Case "WEST"
strMoveToFolderID = strWest
Case Else
strMoveToFolderID = ""
End Select
'This If statement does the actual move
If strMoveToFolderID <> "" Then
Set objMoveMessage = objOneMessage.MoveTo(strMoveToFolderID)
objMoveMessage.Update
'Need to decrement "i" because objInMessages.Count
'has decremented by 1. You need to decrement "i"
'to keep the loops synchronized
i = i - 1
End If
'Test to see of you've examined all the messages
If i = objInMessages.Count Then
Screen.MousePointer = vbNormal
MoveMessageToInboxSubfolder = True
Exit Function
End If
Next i
MoveMessageToInboxSubfolder = True
Screen.MousePointer = vbNormal
Set objInboxFolder = Nothing
Set objInMessages = Nothing
Set objOneMessage = Nothing
Set objMoveMessage = Nothing
Set objInboxFolders = Nothing
Set objMoveToFolder = Nothing
Exit Function
ErrorHandler:
MoveMessageToInboxSubfolder = False
Exit Function
End Function - Add the required sub folders to the Inbox, set your project to start up on Sub Main, and run the above example.
