Looking for Data: A cool framework class

As the article below notes, almost every application needs data searching. In Visual FoxPro, the first time out, many developers use a browse or a grid.

Or a user enters a value into a text box and the code behind it might look like:

IF SEEK(tcValue)
DO FORM details
ENDIF

But from Foxite and Jijo Pappachan, comes a very cool and easy to use Lookup class.

The class handles both SQL and VFP backends with ease, allowing for smart optimization.

Of course, if you're already using a framework, you may already have something like this - but this is something that should certainly be put into an updated FFC on VFPX. If you've ever used the existing FoxPro Foundation Classes search tool, it's pretty limited.

This one is definitely more in line with how applications are looking these days.

The sample pages don't work quite right and it needs a few tweaks to handle large field names but it can be easily called manually.

lo = NEWOBJECT("lookupdata","lookup")
USE Contacts
lo.SelectCmd="select fullname,ctitle,firstname from contacts"
lo.ShowLookup()

It attempts to put a tag name and since tag names have a limit to their field space, it may error out but otherwise it looks quite good.

Hi Andrew,
Thank you for your great interest on this class.
We have now resolved that long field indexing problem and some other bugs.

Well, that explains CodePlex...

In a move that will be sure to anger open source (or rather anti-paid software, anti-Microsoft open source)  zealots, Microsoft is planning to buy GitHub.

A year ago, I mused about why Microsoft would shut down CodePlex and how the world needs competing source code repositories to be strong. I'm not the only one per this Slashdot article :
"...people have warned about GitHub becoming as large as it did as problematic because it concentrates too much of the power to make or break the open source world in a single entity, moreso because there were valid questions about GitHubs financial viability...." - Jacques Mattheij

I will be interested in seeing this play out - whether developers jump ship or not. Have all the efforts Microsoft has made in pushing towards open source be seen as genuine or will all the zealots jump ship or maybe even attack?

Microsoft's comment about why they shut down CodePlex referred to how spammers were using CodePlex. Well, GitHub has its own …

FoxInCloud Stats

FoxInCloud sent this link a while back about their statistics regarding visits to their site:

What's interesting here is the breakdown of people. Yes, I think it's understandable that the Fox community is getting older.

Another factor is the growth of the mobile and web environments taking over development. These environments really do push people towards the newer non-SQL or free SQL/hosted environments but more towards hosted storage options like Amazon and Google. A tool like FoxInCloud that helps MOVE existing applications to the cloud inherently competes with those environments.

But FoxInCloud also allows developers to extend their application further by giving them a starting point using Javascript and the basic CSS (such as Bootstrap). If you're not rebuilding your application from scratch, it's certainly a great step forward.

Attending Southwest Fox 2019 could change your life - Find out how

Southwest Fox is coming up in October and as I do every year, I spoke with the organizers Rick, Doug and Tamar on the FoxShow.

Deadlines for Southwest Fox:
Super-saver price (before July 1): $695
Early-bird price (before August 1): $770
Regular price (August 1 and later): $820
This year, I took a different approach with separate shows for each organizer but the main message is still the same : July 1st is their Go/No-Go date.

Conferences don't talk about this very often. I don't think developers really question if Apple will hold their WWDC in June or Microsoft will hold their Build conference - but that's because those conferences are vendor-led.

Southwest Fox is a community-driven conference - it's not driven by a company with an agenda. Listen to the interviews and you can hear how important each of the organizers feel the live connection between speakers and among attendees.
