It might sound off-topic, but seeing the Xojo style, gives me the impression it is a total rewrite in a VB style language.
I would suggest you rather look at an XBase language like XSharp which you might be surprised have a very similar coding style to FoxPro. Might have your code converted a lot quicker than any other way. Open source, actively developed, .NET based on the MicroSoft C# compiler's open source project Roslyn.

There's a lot there. I'm out of time for the day unfortunately. Let me give you a full response on my thoughts on migrating to Xojo on Monday sometime.

I hijacked the original thread with a reply changing the subject and adding an [NF] flag to the subject because a small comment Kevin made caused me chase a different rabbit for a little bit.
I have reviewed Xojo on a couple of different occasions over the past few years and I have tried to work my way through the book that was written to teach people how to program it and I find myself drifting by the 3rd or 4th chapter every time. Not a fault of the author; just rather a fault of me wanting something a little more advanced. Anyway, I've run into a couple of hurdles with trying to learn Xojo and perhaps someone here has some suggestions to help me out.
Try not to laugh at what may be very dumb questions! :)
I build a lot of similar but customized apps using a shared library of tools I've developed over the past 25 years. Every app I build contains a LOT of forms, reports and programs shared by all my applications as well as a lot of forms, reports and programs which are copied from previous projects and then customized for the current client. While I have seen multiple Xojo advocates confirm a similar process is possible, but I cannot find clear explanations of how to make that happen.
Every Foxpro application I build starts with a .PRG which reads a configuration .INI file and then setups up the environment, displays a splash screen, checks my version numbers, calls a database update process if a version change is detected and if all is good, it displays the main screen for the user. Once the user chooses to exit my application, a shutdown process is initiated and everything is closed in an orderly way. That having been said, I have been unable to find source code to a simple, complete Xojo application or instruction book that can walk me through the start to finish logic and firing order of all the start-up and shut-down events and allow me to compare that to the process I'm so familiar with in Foxpro.
Are there any good white-papers or books by Foxpro programmers that can provide insights into translating my Foxpro knowledge and skill directly into Xojo.
I use Foxpro on a daily basis for my business because I cannot find a language that satisfies my clients' needs the way Foxpro does. I would love to be able to say I have a backup language like Xojo, but I get only so far before I give up and go back to what I know and love. So let's assume Kevin is correct when he states Xojo is " a viable language for VFP developers" because I do not want to go down the rabbit hole of considering all the other alternatives for this sake of this discussion and share with me any tips that can help me understand Xojo on a higher level beyond just creating a simple form. I want to understand Xojo at a Complete Deliverable Application level and talk about mimicking the features I depend upon in Foxpro to share a library of tools, forms and code across hundreds of similar custom applications.

Well, a lot of that article is correct, even though I don't want it to be. VFP as a *language* is as secure as the programmer programmed it to be. VFP as a *database* isn't secure itself. You can encrypt fields. You can encrypt the directory that the data is stored in. But DBF data isn't secure. You wouldn't store social security numbers or credit card numbers in Excel spreadsheets, right?
I've haven't recommended DBFs for storage for over a decade now. There are better storage mechanisms such as Postgres, MariaDB, and even SQLite which can be set up as an encrypted database. VFP as a language is still valid, although it will never be able to create 64bit applications but that is a different subject. [Insert Xojo plug here as a viable language for VFP developers.] I had a potential client where they based their primary keys based on employee Social Security Numbers. They didn't like it when I told them that they'd need a complete rewrite. Notice this would have been the case no matter what language/technology they were using. It was just piss poor design.
It appears from the article, that when the vendor was notified of the situation, that they were able to quickly address it although the article didn't say what that solution was. Probably encrypted the field? Hash the field with an external secured table containing the sensitive data? Who knows. To me, that's a win. Hopefully the vendor contacts all customers notifying them that there is a vulnerability and that there is a solution available.
As Ted Roche always says "Security is a process".

Ignorance and stupidity still runs in the so-called “expert consultant” fraternity.
“An outdated software that is used by about 200 Vermont municipalities and the Vermont Tax Department has long contained flaws that exposed sensitive information including Social Security numbers, according to an IT consultant and the software company’s founder.” “You could make a strong case that Visual FoxPro shouldn’t be used on a government level,” Johnson said.

Thankfully the software owners realise that it isn’t a fault in VFP, it is a fault in the designing of the infrastructure.
