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"

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.

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

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.

Virtual FoxFest - A New Way to Conference

If you haven't been keeping up with the news around the Fox community, the Southwest Fox conference has gone digital now showing up as  Virtual FoxFest .  At $49, it's a steal and a great way to learn some new ideas and get inspired. While the reasoning for this change is fairly obvious with the year of COVID - for me, this is something that has been a long time coming. I appreciate many people's needs for a physical conference but the world is very large and it's difficult to get people from around the world into a single physical location. I recently attended a single-track conference via YouTube (a Quasar conference). YouTube's Live stream provided a very handy way to watch, rewind and communicate with people online. While Tamar, Doug and Rick are still making decisions related to the streaming platform, there are lots of great options available. I'm really looking forward to it. The FoxPro community has also really felt its international roots
