PC MAPI: Compose Requires Compose and Read Values Set to 1 (106068)
The information in this article applies to:
- Microsoft Mail for Windows 3.0
This article was previously published under Q106068 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;;;;;
