More on VFP 6.0
From Robert Green at MS
There has been some confusion voiced here recently about
whether Visual FoxPro would continue to be included in Visual
Studio. I would like to clear this up.
Microsoft is currently hard at work on the next version of Visual
FoxPro. This will ship both in and in conjunction with the next
version of Visual Studio. Let me be totally clear. The next
version of Visual FoxPro will ship as a standalone product and it
will also be available in Visual Studio, both Professional and
Enterprise editions.
At DevCon (Sept 14-17 in San Diego) we will preview the next
version of VFP in the keynote. Paul Gross, VP of Developer
Tools at Microsoft, is the keynote speaker. If you can’t join us at
DevCon, make sure you visit the Visual FoxPro Web site
(www.microsoft.com/vfoxpro) for daily updates.

Check the Registry
The ActiveX control can only be instantiated it it has been
instafled on the user’s computer. If has not, you’ll get a bunch
of nasty errors. One solution
is
to create an object that can
check the registry to make sure the control has been regis-
tered. You may also need to check
for the existence of the
OCX itself. Using this object to check the registry allows you to
trap errors before they happen and if written generically, will
save a lot of coding as you use ActiveX controls more fre-
quently.
Summary
At this point, the real advantage of ChartFX really shows. The
user has a graph the they
can
manipulate, change perspective,
change graph
type,
colors, etc. all using the control’s bufit-in
user interface. This gives casual or non-technical users a very
powerful graphical tool for viewing data with a minimum amount
of effort. This shows very well to potential customers in product
demos and really makes the product stand out of the crown.
