A few months ago, I was approached to assist on maintaining a FoxPro application. The app was developed by an in-house staff person over the last 20 years.
A few weeks afterwards, I received an email from hentzenwerke for this eBook...
So You've Inherited a Visual FoxPro Application. Now What?
It was only $10.
I'm merrily updating this application, moving bits and pieces into ProMatrix. And every 'bad thing' that Whil warned me about came true. And every solution he offered worked.
The best 10 dollars I've ever spent.
