Here is the info that was good when I used it:

Its developer is David E. Lewis.
Query Maker
Strategic Edge
2062 Union St.
Suite 300
San Francisco, CA 94123
(415) 563-3755
FAX: (415) 563-1907

Strategic Edge may be out of business now, but Query Maker is so easy to use that I don't think you would have any trouble. I see that they have a user guide link on the hallogram page.

>Who actually makes that? I always and hesitant about ordering anything from hallogram. They do not provide any info on the company, and they keep software on there years after the company is out of business.

It was very easy to include in an application and has a low price. Our users really liked it also.

>>>Hi all,

>>>Have a client that needs to replace their current VFP report writer with "something new". I have started to look at Stonefield Query (and like what I see) but I know the client is going to ask "what else did you look at" (you know, the "due diligence" thing). I have configured a lot of reports for them in the past and they like these but they have also wanted something that allows them to do more of these themselves.

>>>Any suggestions of ones you *really* like (not just "have used and is okay").
