in outlook 2007, when you have an attachement in a mail message and click on the attachment file, you are presented with an option to preview this attachment directly in outlook...just like the preview pane for a normal message...
...a few handlers of my own. as a developer i frequently get code files sent as attachments. i generally have to open them up and look at them in visual studio or notepad2 for code highlighting, etc. well, with my new found knowledge i created a code preview handler. it will see .cs, .vb, .js and .sql files and enable a previewer to show them in code-highlighted formatting in the preview window of outlook 2007 or windows vista explorer.
