Milind's letter for May is all about Me , er, My

If you check out the Visual FoxPro: May 2006 - Letter from the Editor, Milind refers to the updated CTP documents. Without worrying about the DotNet CTP stuff and the update about Service Pack 2 (note that SP2 will be dealing with some of the stuff they've discovered about Vista), the real cool piece, at least to me, is this little add-on called "My"

As Milind explains it, it essentially contains wrappers for SYS functions and Windows API calls, etc. Why is this a big deal?

I remember a variety of devcons and ER requests for VFP where users would ask for "add a Machine Name function" and the response was "use SYS(0)" or any one of the other SYS functions. SYS was great for functionality but terrible for readability. My makes it a little easier although you have to be used to looking at a lot of "."s.

A lot of code I've seen puts these settings into memory variables for later use. I used to use SYS(0) as my example for using the SUBSTR and ATc function.

lcUserName = SUBSTR(SYS(0),ATC("#",SYS(0))+2)

But now with My, it becomes much easier and I don't really need a variable anymore.

Why bother writing the above when I can use:

IF My.User.UserName="andrew"
...
ENDIF

But My is going to be so much more useable than for things like this. Yeah, it has some stuff like My.Computer.Audio.Play but it also has direct access to the Registry with My.Computer.Registry and lets you retain settings with My.Settings.Add() and My.Settings.Load and Save.

Why bother using AGETFILEVERSION() when you can simply say

My.App.Info.CompanyName and My.App.Info.Version

Yes, if you've been writing code for a while, you likely already have functions for this - for users just starting out ( or for readability with others who may be coming from VB 2005), the My workspace is going to be a lot of fun.

Oh, and did I mention that the help file has a topic about how you can add your own classes to it? Now, THAT Rocks!

Download the feature overview here to get a feel for it. The My spec is actually a help file which makes it even easier to read through and get a feel for.

Hi Andrew, just some hairsplitting detail on your SYS(0) example: a somewhat better approach is:
cUsername = GETWORDNUM(SYS(0),3)

But back to the MY stuff: We will be facing a huge problem: All that My stuff comes bundled within a VCX. Thus using only one tiny MY functionality will suck in the whole My.vcx, which in turn sucks in the whole FFC classes, which in turn suck in all .... Get the picture? As long as there isn't some tool which just extracts the needed resources from any VCX, this will cause lots of troubles.

woody,

Yes - you're right about GETWORDNUM() - good idea!

I agree about the potential size issues with My - which is why it's important that a lot of additional functionality either gets added to it (so that it just becomes so invaluable you can't live with it ) OR someone (who??) builds a tool to do just what you described.


Maybe what we need to is an intelligent "Implements" engine Project hook that creates a specialized class lib that only pulls out what's needed.

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:

http://foxincloud.com/blog/2017/12/27/VFP-community-lessons-from-foxincloud-site.html



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.
