A few months ago, I remember David Crow gave a reply regarding CPU usage to a query, stating something like "What memory usage is shown by the task manager is not actually what memory is consumed by the applications; it could be less". If I remember, he pointed out a very relevent link too. I tried googling, but could not find something satisfying. Tried searching CP for that thread, but could not get. If someone could give me pointers in this direction, I would be very thankful.

I dont know what he said(of course I think he will be answer to you early;)) but I suggest to you see Performance on the MSDN it has a lot of helpful info (Im not sure but I think it was on the VC 6.0)

From The Link
Don't use TM to determine your app's memory usage. Those numbers represent the amount of address space that is in use. They have nothing to do with the amount of that address space your program is actually using.

That's what I wanted. Thank you very much.

Thanks for the link, Roger. But David Crow had once cut shorted this theory into two lines and that was what I was looking for.

It is: Don't use TM to determine your app's memory usage. Those numbers represent the amount of address space that is in use. They have nothing to do with the amount of that address space your program is actually using.

You're most welcome brahmma.

David's statement summrizes it quite well, but if you want "why" answered you should read Newcomer's article.

Indeed Mr. Joseph's website is full of useful information. I am writing a short note on memory allocation, for an internal meet here and that (the info which I've got now) was one thing remaining. So, I took help from you guys. Smile | :)

Why is the below code incorrect in so far as compiler and casts are concerned. In what situations could the same fail?

int __cdecl mythread(void *p)<br />
<br />
AfxBeginThread((AFX_THREADPROC)mythread, NULL);
