Security and stability. If we did nothing else, a lot of
time was taken this release to ensure that this set of
Active X controls was secure. OWC10 was fairly solid but
we went back and took a closer look at anything that could
be used as an exploit and if there was any doubt we closed
the hole. In doing so we also did a lot of work to make
sure that the code we have is stable and robust -- why add
new features when you can make the existing one more
stable?
Better support for .NET programming. 2003 includes
primary Interop assemblies in the box for all of your
programming needs be it VB.Net or C#. OWC is still COM
based but these Office "blessed" IA should make for an
easier time when programming (VS.Net 2003 is recommended
for the best experience).
Better support for JScript. JScript Arrays are better
handled in Chart and Pivot and should now put it on par
with VBScript support as seen in OWC10.
More ways to connect to data in Spreadsheet, Chart, and
PivotTable List. All components can now connect to
Microsoft Business Solutions data sources along with using
a data provider service to connect to Windows SharePoint
Services (WSS) lists or SQL data sources.
Office PivotTable List
Analysis Server 2000 SP3 client bits (PTS) ship in the box
for greater security and stability.
Better support for keyboard navigation and usability,
especially in IE. Tip: Use Shift+Control+f to add a
calculated total.
Richer event processing.
Office Chart
Programmable scroll view. Great for zooming in on a
specific aspect of a chart and BI analysis. See the
ChScrollView object.
Programmable custom formatting to allow for user defined
data markers in bar and column charts. See the
ChChartDraw.OverrideDefaultElementFormatting method.
Programmable chart selection to allow for multiple
selection.
Office Spreadsheet
Better data binding support. In addition to the more data
sources that all the controls can use you can now data
bind the spreadsheet to XML files and SOAP web services.
Excel style data validation.
Web Part interface connections. Using the WSS web part
framework you can connect the spreadsheet to other web
parts. The interfaces include , IFilterConsumer,
IParametersOutProvider, IParametersOutConsumer,
IRowProvider, and IRowConsumer.
