I want to add some functionality to an app so that when a user clicks on an email address it will open up the default email browser, so far I can do this using ShellExecute, however I also want to be able to add an attachment automatically if the user has already selected a file. I was just wondering if there was a way to do this. I'm not sure if ShellExecute would work for this, but even so if there is another way I could target certain apps such as Outlook Express and Eudora by having a command line paramter that adds the attachment that would probably work. Any help is greatly appreciated.
