Gone are the days when we can develop an application using Visual FoxPro alone. Users today are much more sophisticated and expect to be able to use their favorite tools from within the application when it is appropriate. More and more applications are exposing much of their functionality through components which can be automated, including the popular and successful Intuit product "QuickBooks". Your users will thank you for realizing that their time is valuable too when you can automate QuickBooks and make sure that they never again have to enter the same data twice.
