+1 - and a few of us have made detailed suggestions, which are in Ed's Archives.

Paul, No problem you asking here and you will get many types of feedback. I slightly digress from Kurt's diagnosis as I am sure many on here will. We are and have been going through a transition from legacy VFP data containers onto Microsoft SQL and although it is a big job we haven't had to resort to C# or any of the other languages Python etc... VFP is still a great tool to do the front end processing and visualisation layer in projects despite maybe being past its prime and it certainly is as quick in being able to generate front ends even with fancy newstyle looks if you incorporate all the addons that have been developed over the years.
Personally I took time out to develop a set of classes that allow me to run multiple SQL sessions in multiple forms at the same time and we have used them extensively. It takes all the heavy lifting out of SQL data manipulation and leaves you, the developer to concentrate on what VFP does best!!
Mike from MBS has been using MySQL as a back end for years and now everything we do is client server so ask away...

Ok, I've lurked here long enough. I've been subscribed to this list for several months and I have thoroughly enjoyed the questions and answers that have come through during that time. I'm even a little star-struck when I see the names of Foxpro experts that I have depended upon for years to help educate me to be a better Foxpro programmer. Thank you all for all you do in this list group. Now it is time for me to ask what is probably going to sound like a dumb question coming from someone who has been using Foxpro since Foxlan but I figure I have nothing to lose here and everything to gain.
For the past few years I have been honing my skills as a developer of data interfaces and until recently, the few full-fledged data entry projects I've build relied upon native Foxpro dbf files. However, my interface work has been depending more and more upon using SQL pass-through language to issue queries against various SQL backend systems and I have been pretty successful at retrieving data from various systems and then re-formatting that data for other uses.
For a while now, I've been contemplating building a data-entry and maintenance system from the ground up that depends completely upon using a SQL database (Firebird, MySQL, MS SQL, Postgres or something similar). My problem is that I have all these data handling classes built into a couple of simple toolbars that I can drop on form and provide the standard Add, Delete, Undo, Save and Exit functionality as well as a vcr toolbar to skip between records. These tools include all of the code necessary to detect changes enable various buttons based on conditions, etc. stuff we are all familiar with.
Now I'm trying to wrap my head around the whole concept of changing the way I depend upon Foxpro to handle much of the behind the scenes table activity and create a new user interface that conforms to the how SQL works while maintaining as much of the familiar functionality I'm so happy with in Foxpro.
Does anyone have any recommendations for where I should go to learn more about the best practices for developing user interfaces that work efficiently with SQL backends, and what do I need to know about how to collect data and insert it into the sql tables, detect user changes to flag for saving data. In some software they seemed to have ditched the Add, Delete, Undo, Save, Exit concept to just save everytime there is keystroke. And in other systems, they keep parts of that old style of user interaction. Are there any libraries that can be purchased or downloaded to handle some of the behind the scenes data manipulation for SQL that I can use to learn how this stuff should work.
For something that seems to be easy, I'm having a hard time letting go of my 20+ years of doing things the Foxpro way to make the transition.
Any thoughts?
