Hi All,
I'm looking for a method of querying the performance of my projects. Is there a common method for timing functions? Possibly with the aid of adding macros to certain parts of the code?

You could use GetTickCount(), multimedia timer, QueryPerformanceCounter(), profiler. All of these come with pros and cons.

Thanks for the ideas. I have thrown together a bit of code using QueryPerformanceCounter() and created a macro which I can drop into the code. It's not brilliant but it should help me find out where all those slow functions are.

If you can do it in the development environment (and if you can get it to work) the profiler is easy to use and gives more reliable results than GetTickCount().

I have heard of this profiler before, but I never did find out how to use it.

Sorry for the slow response - I don't have Visual studio installed on any available PC at the moment!
First - according to MSDN, the profiler is only available in the Visual C++ professional and Enterprise editions, not standard edition.
Still interested? Then have a look at the following article on MSDN - http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/tmp/_core_run_the_profiler_from_the_development_environment.asp[^]
Note - I have only used the profiler with Visual C++ 6 (with straight C code), and I found that it sometimes was not available (menu option greyed), even though no project settings had been changed.
Good luck - it is worth the effort to get this going.

Yes, you can use CWnd.

Probably the best way to go for that is to create a SDI application and draw on the view directly. I think there is an example in the MSDN about a very simple paint program (you'll have to search for it because I don't remember where it was, I think it was called scribble example).

U can use Rectangle(CDC, rect).. functions from SDK to draw the images....

I think it can help you

Hi all,
Could anybody suggest me a simple method to make a number always odd?
For eg.
Suppose a = 14. After conversion it should be 13.
If it is 13 it should be remain as same.
Thank you.

Assume you have got the number in an int:
int oddNumber = 14;
oddNumber |= 1;
or, as in your question (14 should be 13):
int oddNumber = 14;
oddNumber--;
oddNumber |= 1;
|
|
|
|
|
Yes I need the second one.
That's nice. Thank you.

Your'e welcome.
probably it can be done like this (not tested):
int oddNumber = 14;
--oddNumber |= 1;
|
|
|
|
|
Yes it is working...
Thank you again.

You are making a big assumption that the -- operator will execute before the |= operation.
