My question was naive, I must admit. It is asked too much to expect modules built with other tools/languages to be aware of all that vfp-apps are aware of. Having admitted that, I now realize it IS important to be aware of this when people (e.g. of Microsoft) claim that new extensions can be built with other tools/languages. In the case of many (vfp) legacy applications that will imply that new extensions will have to act (e.g. upon a database) asif it were a separate executable. So, it will have NO knowledge of the state of variables and settings. And tables will have to be opened as in a private datasession. I think this is all doable, but it will require some (some?) redesign before it can actually be implemented.


>You can build Windows apps today that can watch things.. UI updates, changes in variable values, etc. I don't think we can have an application be aware of open tables without a lot of work. The common way to connect to data in ,Net is through some type of data provider. Think ODBC, but there are other options. Just as in VFP, you can't be aware of what ODBC has open behind the scenes, you can't be aware of that in .Net. To make it work, you'd have to handle all the file open/close/etc yourself. I'm not sure it gains us that much to maintain all that code.

>>In 2015 Microsoft introduced the phrase 'Windows Desktop Apps' for PC-applications. This month they demonstrated the preview of the ‘Desktop App Converter’. The claim is that legacy apps can run without much adaptations inside a 'container'. Moreover, extensions can be built with the legacy platform, but also with newer platforms.
