Randy demos
New limits: arrays > 64k
Program code (individual procedures) unlimited
Huge number of features of SQL: 
    No limit on joins No limit on subqueries No limit on UNIONs No limit on # of tables No limit on IN() args Multiple subquery nesting GROUP BY in correlated subquery Sub-select in FROM clause Subquery in select list projection ORDER BY using field name with UNION clause Optimize LIKE "sometext%" Optimize TOP N UNIONs in INSERT INTO ·.SELECT Subquey in UPDATE Correlate INSERT/DELETE Optimize deleted tags
New data types ö VarBinary, timestamp, VarChar (field width actually returns VarChar length), CAST() function ICASE() function Binary index÷smaller than existing indexes (up to 30x). Size maintained during replace, only increases on append. Toolbox feature with dock-ability for native VFP form Anchoring for resizable forms- no code running Button graphic alignment with text ö spacing between graphics and text: PictureMargin, PictureSpacing Example of graphical button with hotkey Checkboxes with multi-line text Listboxes can hide the scrollbar if there aren't enough items to fill the list Listbox RowSourceType of ãCollectionä Grid MousePointer and MouseIcon property in Column and Header properties Themes in labels support ãGroupBoxCaptionä GDI support for labels ö let's you specify an angle or rotate at runtime! Polylines and Polygons Bells and Whistles, arrow and shapes Project manager will allow you to open Class Library in Class Browser. When docked, there are many more items on the context menu. Can load PRGs in Class Browser. Property sheet: cursorschema string was limited to 255 characters from CursorAdaptor builder Zoom dialog supports extended characters, like carriage return for captions ExpressionBuilder with syntax coloring and background compiling Add property features with default value! Calvin video: new property dialog, default value, no longer limited to 255 characters, too.

Running user code in the property window reads a memo field and can execute script (IntelliSense in the memo field!) wrapped in XML. Example of Inputbox() call to prompt for custom properties. This might support Capitalization for custom properties or ãFavoritesä tab for property sheet.

Happy birthday to me

Got a surprise birthday party, cake and all, when friends interrupted my pre-conference session wth 5 minutes to go to sing “Happy Birthday.” Attendees seemed amused. After one refrain, they let me get back to finishing the presentation, only 10 minutes late or so. Carrot cake, a clever card and a golf club cover in the shape of a fox made it a fun birthday surprise.

The conference starts in earnest in two hours, with an 8 AM keynote. Reception tonight and a bonus session, an outdoor dinner and another bonus session tomorrow night will round out the schedule. We’ll be busy.
