Comments
from the
Editor
==========================================================
It’s the week before Christmas and all through the office, not a creature is
stirring not even a mouse Okay, a few mouses are stirring and so are a few
trackballs!
With Christmas next week and New Years the week after, things often slow down
at this time of year. I find it a great time to do some additional writing and
to focus on figuring out projects I want to accomplish in the next year. It
seems that over at Microsoft they have been trying to wrap of the year in a
similar way in regard to Visual Studio.
Last Friday Microsoft released Service Pack 1 (SP1) for Visual Studio 2005.
This is an update that provides bug fixes and other updates. In a release
Microsoft stated that they have included more than 70 improvements in this
release. This includes updates based on feedback from users to better support
for all the new multi-processors that have been released recently.
Equally important, Microsoft is also thinking about next year as well. They
released a beta Service Pack 1 for Vista (called Visual Studio 2005 SP1 Update
for Windows Vista Beta). Visual Studio 2005 is an unsupported application on
Vista at this time, so it is critical for Microsoft to get the appropriate fixes
to us as soon as possible. While I believe the service pack should have been
available November 30th with the official release of Vista, it wasn’t. As such,
a beta now is at least a start in the right direction. The final release of the
Visual Studio SP1 for Vista should be available at the time Vista is generally
available (figure around January 30th).
For more on the SP1, you can go to:

Happy Holidays!
Until next week…
Brad!

This week’s CodeGuru posts:
==> AJAX
– [Updated] Convert Your Scraps of Script to Reusable AJAX
Control Extenders

==> C# Syntax
– Flags Enumerations
By David
Oldfield
The documentation on Microsoft’s flags enumerations is rather
sketchy at best, but offers a more ideal solution for a great many problems. The
problem is, with such little documentation it can be very time consuming to
figure out how to use them correctly. Here is a small walkthrough explaining a
relatively simple means of interacting with them through use of the bitwise OR
operator.

insights about code modularity and reuse using Aspect-Oriented Programming
(AOP).

2. Using Google Web Toolkit to Access SQL Anywhere Web
Services
By Rob Close –
If you have ever
written JavaScript targeted at multiple browsers, you will know that it can be
tricky having everything work as expected in every browser. To get around that
problem, GWT generates scripts for several popular browsers. Once you know the
steps, getting Google Web Toolkit working with SQL Anywhere is a straightforward
process.
