Thanks Brian.  I haven't been active in the Wix community.  What is the DTF?

Hey Craig,

I don't have any good C/C++ examples on hand. I *believe* that the DTF examples 
have something similar that you could just translate.

I would recommend schedule tasks. Leaves very little room for debugging and a 
bit more difficult (IMHO) to get setup correctly.

Thanks,

Brian Rogers

  I am investigating what's involved in writing an automatic updater for my 
software.  Can anyone point me to a good technical document on how to do simple 
tasks in C/C++ such as iterate through the installed applications?

  My software has multiple parts, each of which is installed with a different 
installer.  I only want to download updates for those parts of the product that 
have been installed.  When the updater runs, I'm thinking that it should:

  - Determine which applications are installed
  - Hit a website for a small text file with the current version (1 per 
installed application)
  - If the new version is greater than the installed version, download the 
update (msi) and run it.

  I haven't decided if this will run in the background as a service, a 
scheduled task, or be a manual operation but that is secondary to getting the 
basic functionality working.

  If this post is better suited to the wix-users list, please let me know.  I 
asked here because it seemed like it might be something that the core team 
might be interested in having if I get it working in a flexible way.

  Thanks for the help
  Craig
