Or by setting the house on fire and see if someone gets out screaming... But ok, that may not be the most elegant solution

Yeah, but after you see that someone is home, they'll be gone afterwards..

Can anyone suggest a way of detecting whether a CD or DVD is present in a drive without trying to access that drive?
Nope, It not possible

Know the weight of your PC when no CD or DVD is present...
Whenever you wish to know if there is a CD or DVD in the drive, measure the weight of the PC again, and check if the weight has increased with the weigth of a CD.
(you could place your pc on a digital scale and connect the scales to your pc and use the output of the scales to check if a CD or DVD is present programmatically )

What about when more and more data is cached to/from RAM? Won't that affect how much it weighs?

Yes, because the heat of the PC will build up, and this might cause counter-convection, in which case the computer case will be slightly uplifted, thus weighting less. Also, depending upon case fan placement, when they spin at higher RPM to remove the excess heat caused by the burdening of the RAM, the fans might provide a slightly uplifting effect to the computer case, thus giving false readings during the IsCDPresent() function call :->

hi, i am some newb in MFC programming now dealing with some problems while learning other's codes
[IMG]http://img145.echo.cx/img145/8175/cstring3uk.jpg[/IMG]
as you can see from the image, i am running debugging mode going step by step up to that yellow arrow (circled in red)
i noticed that in the "watcher" section at the bottom right it says the symbol "str" is not found
what puzzles me is that "str" has already been declared already (circled in red) and how is it possible that it cannot be found?
shouldnt it be some text? or at least empty text "" ?
i hovered my mouse over "str" and nothing came up 
could it be some declarations i left out? i got no idea
please advise and enlighten me :wave:
- winxp
- VC6.0++, SP5
- MFC style

Which part of Please do NOT post programming questions or ads to this forum didn't you understand?
Before the others give you grief, go to the right forum; and delete this post unless you want to be flamed.

It's all Nish's fault. Look at the title of his post below. It's misleading other people to think that this is a programming forum.

Yep! a typical case of "One rule for one, another rule for another", which seems be case in the lounge. Depending on your popularity factor, posting Programming or near Programming question, a 'blind eye' will be taken.

I suppose it depends on your point of view. To me, Nish didn't post a programming question. He started a discussion on a programming subject. He wasn't asking for help with his programming, he was asking for a point of view on a programming concept. I don't know about you, but this is the kind of thing me and other programmers discuss over lunch or other non-working get-togethers. So I think it is a valid lounge topic.

Though both norm.net and you have valid points, I'm more likely to side with you.

It gets to a fine line discussion/question I'm not splitting hairs, I've seen newbies and near newbies dragged backwards through the bushes for posting similar messages, yet when a popular long timer posts similar material the blind eye approach is taken. It's merely an general observation and my opinion.

You have a fair point.
Newbies on any site always get a rougher time than those who are on the staff or who are well-respected members of the community. (You should look-up some of the hassle that Nish got when he first joined)

WHAT? 
> old
I'm 21 years young.
> message board
Yes, this is indeed a message board.
> nazi
I'm North Indian, which I guess makes me Aryan, but I'm certainly not racist, so I don't see how I can be called a Nazi.
> fart
I eat healthy food, and I eat in moderation. It's a long time since I f*rted.
Only one out of your four charges is valid. And I don't think posting on a message board is a crime.
Are you criticizing me for my previous post? If so, I'm sorry, you're mistaken. Was my post in any way combative or threatening or demeaning? I certainly think I was polite, but if you disagree, I can't help it.
Cheers,
Vikram.

Nope. Not in the least bit. If somebody thinks I made a mistake, I explain my side of the argument. But if they persist, they're free to disagree.
