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.
