Hi Johan,

>I am an active X# developer.

A warm thank-you for dropping in!

>I was directed here by a VFP developer, and yes sorry I and I believe the DevTeam was not even aware of this forum.

Should the X# team have a genuine interest into VFP both as a community and as a development platform, you should possibly publish regularly onto this historic place of the fox community. It is not as active as it used to be. But it still convey a decent readership especially among long-time experts of VFP!

>X# is really aiming at supporting VFP syntax 100%. A lot of VFP specifics are already supported e.g. TEXT...ENDTEXT, WITH...ENDWITH, SCAN... ENDSCAN etc.
>All standard XBase commands are also supported. What is currently under development is the VFP DEFINE CLASS.
>Once that is in place inroads will be made into the rest >like UI VCX, SCX etc and cursors.
>All the supported VFP features was added in basically 6 months so I believe quite an achievement.
>There are already paid members of >VFP like Matt Slay and Eric Selje who will present a session at SWFOX, so just bear a bit since I do believe things will really start moving after SWFOX.

Great to hear this. I really look forward to hearing news about the development path!

I'm of course impressed to hear that X# could transparently support alternative xbase-orientated syntaxes. Shouid the performance be acceptable, this is "in and of itself" impressive... I'll specifically follow on two fields where VFP really shined (and still is decent over 12 years after it lost MS support) : fast prototyping-and-building of data-aware UI and, more important as as I am concerned, the quality and speed of its local-cursor-based SQL engine.

Have you an idea how Visual Object or Vulcan (if that's the name) did perform in this very area ?

Sure the combination of local partially in-memory dbf-based cursors and associated indexes (following the cdx format) delivers impressive data mangling performance. I expect that quite a number of those still use VFP would possibly still rely on this engine. Even in cases when they use db-server technology. I'd be glad to hear how the dbf currently fits in the X#combination.

By the way I can certainly wait for the feedback of the community after SouthWest Fox by the end of this month:-)

Regards, Daniel
