BUG: CDO Message.Text Property May Return Truncated

ID: Q192910

The information in this article applies to:

SYMPTOMS

If a Collaboration Data Objects (CDO) application runs on a Chinese Traditional (CHT) or Chinese Simplified (CHS) Windows NT system, the Text property of the message may return truncated. For this to occur, the PR_BODY property of the message must be a Multi-Byte Character Set (MBCS) and contain a mix of American National Standards Institute (ANSI) and MBCS characters in the first 255 characters of the message.

The following sample Visual Basic code fragment shows how one might read the Text property of a message object using CDO: 


Set sessionObj = CreateObject("MAPI.Session")
sessionObj.logon "TestUser", "TestUser", 0

Set InboxObj = sessionObj.Inbox
Set messageCol = InboxObj.Messages
Leng = messageCol.Count
Set messageFilter = messageCol.Filter
messageFilter.Unread = True

Set pMessage = messageCol.GetFirst
retv = pMessage.Text

If the preceding conditions are met, when you display retv, it is truncated to the first 255 characters of the message.


CAUSE

A logic problem is preventing CDO from detecting that the Text property has been truncated.
