Some more new features of Tahoe I haven't seen discussed here:

- A new SYS() command that allows you to have more complex WHERE clauses in SQL statements. Particularly good for views that have lots of updateable fields. This would sometimes make the WHERE clause more complex than VFP could handle (more than 40 fields in the WHERE according to Tahoe's help). If you've been getting "SQL Statement too long" in TABLEUPDATE(), this should fix it.

- NEWOBJECT() function like CREATEOBJECT() but lets you specify the VCX so you don't have to SET CLASS LIBRARY first.

- Pass arrays to COM objects by value or reference.

- Trap crashes in COM objects and avoid VFP GPFs when an object crashes.

- Specify how many items appear when a combo-box drops down.

- GridHitTest() helps you determine where in a grid the user clicked. Or dropped an item.

- Images and labels include ToolTipText option. This will simplify making those Office 97-like buttons.

- CREATE FORM AS allows you to create a form from any class easily.

- Lots of FoxTools functions are now in the language.

- You can convert files to strings and vice-versa using FILETOSTR() AND STRTOFILE(). Also, string processing is much faster. All of this will help with things like generating and interpreting HTML/XML.

Any questions?
