Sample Simple MAPI Client 
 
 
The Simple.Cli sample application illustrates using Simple MAPI functions. 
 
The sample is a very simple mail client. Using it is intuitive and 
straightforward. 
 
To run this application, you have to have MAPI run-time binaries installed on 
your system. For installation instructions, see the readme.wri in the 
mstools\mapi\ directory. 
 
When writing simple MAPI applications, the addresses of all of the simple 
MAPI functions has to be obtained explicitly (using GetProcAddress), as 
opposed to linking to the import library for MAPI.DLL. 
 
If sending/receiving mail is not the primary function of your application, you 
can test presence of simple MAPI in a system without incurring high cost of 
trying to load a DLL. You can test the value of the MAPI variable. It is 1 if 
simple MAPI is installed. The variable is located in the [mail] section of 
win.ini on 16-bit Windows and Windows NT version 3.51 and earlier and under 
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Messaging Subsystem in the 
registry on Windows 95 and Windows NT 4.0 and later. 
 
Known Problems 
-------------- 
 
When you Reply All to a message that you sent to yourself, your name will 
appear twice in the To well. This is caused by the fact that Simple MAPI 
does not expose either search key or a way to compare entry IDs, so there is 
no safe way to remove duplicates from the recipient list.
