• Path variable to mso.dll and msoutl.olb

  - by Stefanie

  Hey, I'm trying to develop a toolbar for Microsoft Outlook. For getting it to work I need mso.dll and msoutl.olb as an import. My problem is: the path is hardcoded , but it varies for every OS and of course if someone doesn't install Office to the default path. I tried it this way http://support.microsoft.com/kb/234788/en-us/ but it didn't work, because I couldn't get the return value I needed (OK, after four type conversions but I thought there had to be a better way ;) ) Thanks for helping

• How long is a CS degree good for?

  - by Recursion

  I came upon a comment on another forum today and one user responding to another suggested that a CS degree is really only good for one through two years at the most, and after that its as if you never had it. Is this really true? is this what employers think? When I did CS I never learned anything new, we learned fundamentals like data structures, algorithms, time complexity, OS fundamentals, language characteristics. Most of this stuff has been around for the past 20 years or so.

• Windows Application Data Directory

  - by JP

  Not completely a programming question, but its close enough so here goes: In Mac OS I'll put user-specific files for my app in ~/Library/Application Data/{MyApp}/ and in *nix I'll put them in ~/.{MyApp}/ - where should I put them for Windows? I'll be using Ruby's File.expand_path to get to this directory, so if there's a windows equivalent of ~ then that's fine. (Answers for Windows XP, Vista and 7 would be appreciated if they're not the same)
