DLL to read and write RTF with Active Messaging

This article was previously published under Q172038
SUMMARY
When writing an Active Messaging client, it would be useful to be able to use rich text formatting (RTF) in the body of the messages that are created. However, the Active Messaging Libraries provide access only to the plain text version of the body of the message, giving no control over the font characteristics of the message body.

This sample contains a DLL with functions that may be called from an Active Messaging client to read and write RTF text of a message.

The following are the contents of the Readme.txt file for this sample.
MAPIRTF Sample--------------This sample illustrates how use Extended MAPI to allow RTF-formatting in amessage created by Active Messaging.NOTE: If you are working against Exchange 2000 Server, you need to rebuild Mapirtf.dll using the C++ source Mapirtf.cpp provided in this article.Specifically, we need to call RTFSync with RTF_SYNC_RTF_CHANGED | RTF_SYNC_BODY_CHANGED for the ulFlags parameter.hr = RTFSync(lpMsg, RTF_SYNC_BODY_CHANGED | RTF_SYNC_RTF_CHANGED, &fUpdated);Files-----The self-extracting executable, Mapirtf.exe, contains the followingfiles: - Readme.txt: Contains information about the sample - Mapirtf.dll: The release version of the DLL - Mapirtfd.dll: The debug version of the DLL - Vbmaprtf.exe: Microsoft Visual Basic Active Messaging client - Vbmaprtf.pdb: Debug symbols for Vbmaprtf.exe - CSource Folder: Contains the source file and Microsoft Visual C++   version 5.0 workspace and project files for Mapirtf(d).dll - VBSource Folder: Contains the Microsoft Visual Basic version 5.0   project, form, and module files for Vbmaprtf.exeGeneral-------The files Mapirtf.dll (release version) and Mapirtfd.dll (debugversion) contain the following functions: - "Writertf" writes RTF-formatted text to a message created by   Active Messaging, when passed the profile name, entry ID of   the message, entry ID of the message store, and the RTF text. - "Readrtf" reads RTF-formatted text from a message when passed   the profile name, entry ID of the message, entry ID of the   message store, and a string variable to which to store the text.How to Use----------Before use, the DLL files should be placed in the Windows\Systemdirectory (for Windows 95) or the Winnt\System32 directory (forWindows NT.In Visual Basic, declare the functions as follows:    ' For the Debug version of the DLL, remark the following lines    Public Declare Function writertf _        Lib "mapirtf.dll" _                         (ByVal ProfileName As String, _                          ByVal MessageID As String, _                          ByVal StoreID As String, _                          ByVal cText As String) _        As Integer    Public Declare Function readrtf _        Lib "mapirtf.dll" _                      (ByVal ProfileName As String, _                       ByVal SrcMsgID As String, _                       ByVal SrcStoreID As String, _                       ByRef MsgRTF As String) _        As Integer    ' For the Debug version of the DLL, un-remark the following lines    'Public Declare Function writertf _        Lib "mapirtfd.dll" _                         (ByVal ProfileName As String, _                          ByVal MessageID As String, _                          ByVal StoreID As String, _                          ByVal cText As String) _        As Integer    'Public Declare Function readrtf _        Lib "mapirtfd.dll" _                      (ByVal ProfileName As String, _                       ByVal SrcMsgID As String, _                       ByVal SrcStoreID As String, _                       ByRef MsgRTF As String) _        As IntegerSample Code-----------The following sample code assumes that you have already declared the DLLfunction as described above. For a more complete example, please see theVisual Basic project accompanying this sample. - WriteRTF Sample. (This code assumes you already have a variable   called cRTF defined which contains RTF-formatted text.)    Sub SendRTF()      Dim objSession, objMessage, objMessageFilter As Object      Dim MessageID As String      Dim bRet As Integer      Set objSession = CreateObject("MAPI.Session")      objSession.Logon      ' Create a new message      Set objMessage = objSession.Outbox.Messages.Add      objMessage.Update      MessageID = objMessage.ID      bRet = WriteRTF(objSession.Name, objMessage.ID, _                      objMessage.StoreID, cRTF)      If Not bRet = 0 Then         MsgBox "RTF Not Written Successfully", vbOKOnly, "VBSendRTF Warning"      End If      'Clear our current variable       Set objMessage = Nothing       ' Get our message      Set objMessage = objSession.GetMessage(MessageID)       ' Send the Message      objMessage.Send ShowDialog:=True      objSession.Logoff    End Sub - ReadRTF Sample.    Sub ReadRTF()      Dim objSession, objMessage, objMessageFilter As Object      Dim MessageID, cRTF As String      Dim bRet As Integer      Set objSession = CreateObject("MAPI.Session")      objSession.Logon      ' Read the first message in the Inbox      Set objMessage = objSession.Inbox.Messages(1)      objMessage.Update  ' to get a permanent Entry ID      MessageID = objMessage.ID      ' We must initialize the string variable we are passing      ' to a string of the maximum length we want to read      cRTF = Space(500)      bRet = ReadRTF(objSession.Name, objMessage.ID, _                      objMessage.StoreID, cRTF)      If Not bRet = 0 Then         MsgBox "RTF Not Written Successfully"      Else         MsgBox "RTF Text: " & Chr(13) & cRTF      End If      Set objMessage = Nothing      objSession.Logoff      Set objSession = Nothing    End Sub
