Question for the VFP team: Why can't the debugger get the code?

There are many reasons why the debugger can't always get the code but as a developer, one always wants to ask.
 
I have several apps. I turn on "Include Debugger code" in the project manager. When an error occurs, why can't the debugger find the information?
 
Yes. The debugger can read the Class code and shows it. but PRG files (where many developers keep their code) are kept hidden from this area.
 
There may be ways around it but WHY can't VFP read the "include debugging" code from program files?

Do you have sample code to reproduce your scenario?
Are you running an EXE? Are you DOing an APP or EXE from the command window?
Repro code shows unambiguously what you mean.

Typically this happens when you have your source in one directory where you build your project and then you are running it in another directory and then trying to debug it.

Simplest steps to reproduce:

Build a project:
MAIN.PRG
DO FORM X

Function WhatsmyName
IF SYS(0)="andrew"
RETURN "Good"
ELSE

RETURN "Bad"
ENDIF

The form has a button on it that does
MESSAGEBOX(WhatsMyName())

Now build this as an EXE or an APP.

If you run it in your Dev environment and use the debugger, you can see all of the code.

Copy the app to another folder, restart VFP and then try again using the debugger with a Breakpoint on PROGRAM(). The code in the BUTTON click will show but the code in MAIN.PRG will be "Source Not Available"

Make sense?

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
