specifying messages for type 19 error custom actions
i'd like to be able to use type 19 CAs for every error that will cause setup to abort. this, i understand, is the proper way to do things as it makes an application event log entry instead of displaying a message box, if the thing is being run silently. besides, i was taught in an IS class that that's the way to go. 🙂
what i didn't get was how i can customize the display message during deferred-execution, or for that matter, how i could set a property upon which the condition for that error CA can depend?
it all seemed to make sense in class when i wasn't thinkging of these details, but as i sit writing a des spec, i'm not sure if it's such a good idea anymore.
okay, i went over my course material and was reminded of the MsiProcessMessage api, which can be used to throw these errors from a CA. All set! Life is good!
