CCMC v1.04 A set of MFC classes to
encapsulate sending mail using CMC (Obsolete)
Welcome to CCMC, 2 simple classes to
encapsulate sending mail using the Common Messaging Calls (CMC) interface.
CMC is a platform independent API which provides messaging
capabilities similar to simple MAPI on Windows. Other obvious API's of use to
the MFC programmer are SMTP and Simple MAPI. The author has provided
classes for these at smtp.html
and cmapi.html
respectively. This class has been exclusively tested with the MS reference
implementation of CMC but should work ok with any other CMC implementation on
32 bit Windows.
Features
- Simple and clean C++
interface.
- All the code is UNICODE
compliant and build configurations are provided for this. Even though CMC only exports an ASCII versions of it's functions, the class internally
performs the necessary conversions. Please note that since the API is ASCII
based, you will still have problems if you use UNICODE characters which
cannot be represented in the ASCII code page.
- The code can be used in a
console application or without bringing up any CMC dialogs if so desired.
- The code gracefully handles
the case where CMC is not installed on client machines. Internally the
class loads the DLL and uses GetProcAddress calls.
The enclosed
zip file contains the source code
and a simple test program to exercise all of the functions the classes provide.
Copyright
- You are allowed to include the source code in
any product (commercial, shareware, freeware or otherwise) when your product
is released in binary form.
- You are allowed to modify the source code in
any way you want except you cannot modify the copyright details at the top
of each module.
- If you want to distribute source code with
your application, then you are only allowed to distribute versions released
by the author. This is to maintain a single distribution point for the
source code.
Updates
V1.0 (25 November 1999)
V1.01 (28 March 2000)
- Provision of a sample app which implements a mini mail
sender.
- Added a CCMCMessage::AddMultipleRecipients method
similar to my SMTP class.
V1.02 (2 April 2000)
- Password field in the configuration dialog now uses
ES_PASSWORD edit control style.
- Password value used for CMC logon is now stored in the
registry encrypted instead of as plain text.
V1.03 (22 December 2006)
- Updated copyright details
- Made function pointer typedefs part of the CCMCSession class
- Updated the code to clean compile on VC 2005.
- CCMCMessage::AddMultipleRecipients method now has a return value of void
- Optimized CCMCSession constructor code
- Addition of a CCMCMessage::AddMultipleAttachements method
- Code now uses newer C++ style casts instead of C style casts.
- Reviewed all TRACE statements for correctness
- Fixed problems when the code is compiled for UNICODE. The issue was that
the Send method was using the various T2A macros which allocates a stack
based string. This was causing issues because the recipients and attachments
array for the CMC message was being allocated in loops which was using
scoping. This scoping was causing the stack based strings to be deallocated
before the "cmc_send" method was called. This issue has now been fixed by
the introduction of new generic heap based macros in PJNConv.h which
allocates the converted string using the C++ new operator. To ensure orderly
cleanup of this heap memory, the CMC_message structure is now allocated
using a hidden C++ class "CCMC_messageCleanup" which cleans up this memory
automatically in its destructor.
- General review of the code to bring it up to date with the author's
simple MAPI class.
- Addition of a CCMC_EXT_CLASS preprocessor macro to allow the classes to
be more easily added to an extension dll
V1.04 (1 January 2007)
- Updated copyright details.
- Fixed incorrect usage of preprocessor macro in
CCMCMessage::AddMultipleRecipients method
31 March 2008
- Please note that this code is now obsolete because Microsoft has dropped
support for CMC as far back as June 2000 with a security update for Outlook. For more information please see
http://support.microsoft.com/kb/262701. You should
update your code to use this other mail delivery mechanisms such as Simple
MAPI, Extended MAPI, SMTP or CDO.
