… CodeGuru Badges


There have been a number of requests made for changes and enhancements to
CodeGuru. We’ve made many of these and continue to forge ahead with more. One of
the most recent items that we’ve done in response to a request is to create
CodeGuru badges. These badges are graphics that you can use on your site to link
to your profile on CodeGuru or to the site in general. There are three different
types of badges each in two different sizes.


You can get to the graphic badges in the site FAQs at:


http://nl.internet.com/ct.html?rtr=on&s=1,u1i,1,c00c,ps1,jorm,i5r0

If
you use these on your site, let me know. This isn’t mandatory, I’m just
interested in seeing how you use them!

… Quiz Question!


Last week’s question was relatively easy. Even as an easy question, it was
interesting to see how many people asked if the problem was the use of single
quotes instead of double quotes. Let me say that a character pointer can point
at a single character! That was not an issue.


To refresh your memory, last week’s question was:


     Are all three of the following valid
declarations for a character pointer?


          const char * myPtr =
‘A’;
          char * const myPtr =
‘A’;
          const char * const
myPtr = ‘A’;


     What is the difference between each of the valid
ones?


The answer is yes! they are all three valid and correct. The difference was
in the constant declarations of each of these. A couple of people were able to
point out the differences.


The first one (const char * myPtr) declares a pointer to a constant
character. You cannot use this pointer to change the value being pointed to:


char myCh1 = ‘A’;
const char * myPtr = &myCh1;
*myPtr = ‘J’; //
error – can’t change value of *myPtr


The second one (char * const myPtr) declares a constant pointer to a
character. The location stored in the pointer cannot change. You cannot change
where this pointer points:


char myCh1 = ‘A’;
char myCh2 = ‘B’;
char * const myPtr =
&myCh1;
myPtr = &myCh2; // error – can’t change address of myPtr


The third declares a pointer to a character where both the pointer value and
the value being pointed at will not change.


Next week I’ll ask an even easier question than this one. If you have a
question you’d like to see posted, then send the question and the answer to me
at [email protected]. Indicate
in the message it is for consideration for the newsletter!


… Releases and News


In keeping up with some of the betas –


The impact of reallocating some resources from Longhorn to Service Pack
2 means that the first beta for Longhorn is now expected in early 2005 instead
of late 2004,


This is a quote from, “Longhorn’s Delay Expectations” posted to
InternetNews.com. This news release also mentions the possibility of cuts to
WinFS in Longhorn. For more, check out the full news article at:


http://www.internetnews.com/dev-news/article.php/3338691


Part of the delays to Longhorn are a result of the SP 2 Release of Windows
2003. InternetNews interviewed Tony Goodhew at Microsoft about this release.
Tony’s interview can be found at:

Until next week!
