In our app we are using MAPISendMail to send an email with an attachment. In ANSI mode everything works fine. However, once in Unicode mode it no longer works. The problem is that MapiFileDesc and MapiMessage only take LPSTR as strings. So when I have a Unicode file that is filled with Asian characters there is no way to pass that string to the MAPI stuff. Seems to me like I cannot use MAPI in this instance. Can anyone recommend another way of lauching the system's default email app and adding an attachment to it? Or if there is a way to modify the MAPI code that would work as well.
