How can I tell if the address book is installed or not? (using mfc)

if its installed i need a way to extract the information from it.

I need to know how to program it, frankly.

Not much about WAB.exe on CG or many other sites. Microsofts code examples are a solution but their code example of WAB programming is using the win32api and I want a less error prone way of doing this.

Ideas on a postcard
