SUMMARY
When you use using version 3.0 of Messaging Application Program Interface (MAPI), the Compose operation is a combination of creating a message and opening it. You can only subclass a message's Compose function when you subclass the message's Open function. Therefore, in order for a dynamic- link library (DLL) to be called when you select the Compose button, both the Compose and Read operation flags must be 1. In addition, the Compose button is only tied to the IPM.Microsoft Mail.Note type.

Example
Below is an example of the MSMAIL.INI [Custom Messages] section. This example starts the Notepad program when you select the Compose button. NOTE: The Read operation is set to 1 in the working example.

The following example works:

IPM.Microsoft

Mail.Note=3.0;;;;appexec.dll;notepad.exe;1100000000000000;;;;;

The following example does not work:

IPM.Microsoft

Mail.Note=3.0;;;;appexec.dll;notepad.exe;1000000000000000;;;;;

Additional query words: 3.00
