Please excuse the basicness of this question but I just got to know.
Which Comes First: The C or The C++??
I have heard it both ways:
Learn the basics of C then start C++.
Do not Lean C first you may form bad habits and is a waste of time.
Is it that there is not a definitive answer or that someone just can't decide? I am guessing personal perference??
Thanks

What does your boss need you to know? The first concern is always what you need today.
I've known several programers that were excellent at C, but never did figure out C++ despite using C++ for years, they were too stuck in the C world. So from that point, it is better to learn C++ first, in hopes that you learn to think about objects from the start.

Hello everyone.
I write a video capture programe based MDI using MS driectshow ,the
video is captured from CCD camera， i need to preview the real-time
video ,how can i preview the video at one windows of the MDI program.

Thank you!

I know how to preview the video to the windows using its hwnd.but i don't konw how to preview the video to a MDI program.
|
|

|

Well, an MDI window has a HWND. Just use the HWND of your view.

hi, um i am not sure if this is the right spot to post but i am having a small problem in c++. I have a class that holds a pointer to a struct.
struct somestruct {
someval
};
class someclass {
somestruct* pointer;
}classpointer*;
when i do this:
classpointer->pointer->someval = something;
i get a error i have no idea how to fix it
thanks

The default member access for a class is private, so you can't access pointer outside of the class unless you declare it as public.
class someclass {
public:
somestruct* pointer;
}classpointer*;

to add to the other answer, I assume that point is actually allocated ?
anyway, is it a compilation error or a runtime error ?

Hey-
How does one app go about putting a button on the title bar of another window?
I've seen AOL and WebEx do this?
They place a button, which receives events, and posts a pop-up menu.
Thanks in advance

By implementing a hook. See this[^] article for an example.

I have six lines in my code similar to the following:
Biquad[0]->mfVh = pow(10, (0.05*mfGh));
On compiling the program I get the following error:
error c2666: 'pow': 7 overloads have similar conversions.
Could somebody explain to me what this means.
Biquad[i] is an object of cBiquad.
mfVh and mfGh are floats.
I've tried suffixing 10 and 0.05 with f, but that gives me a separate error saying that the use of the suffix there is incorrect.
If you could let me know what I'm doing wrong it would be of great help! Thanks!

I seem to have fixed it by some kind of brute casting technique.
The line now reads:
Biquad[0]->mfVh =
pow((float)10, (float)(0.05*mfGh));
Here's a link to the MSDN document if somebody else has a similar problem
ERROR C2666
Suggestions for more elegant solutions are welcome!

I had the same problem. Are you using VS2003? It doesnt seem to be a problem in vs6
Change your code like this. Its a bit neater
Biquad[0]->mfVh = ::pow(10.0, 0.05*mfGh);

Josh,
Thanks for the tip, and yes, I'm using VS2003. That's a really weird error...digging through the MSDN documentation helped a little and I typecasted everything that could be (even the result, but apparently that wasn't required).
I like your solution better. Could you please explain what the "::" does?
Thanks again!

The :: means "the pow() function from the globalname space". This is redundant if you dont use namespaces, and probably if you do but I like to use it when calling functions from the c library as it makes the code a bit easier to read im my opinion.
Look at the declaration of the pow() template function in math.h if you are still unsure about how to use it

(I have post it on another forum, but I'd like to offer it first to MFC friends, don't call it as cross-post!)
Image copier is the best image tool in the world developed for artists, programmers and normal users, such as company managers, office staffs.
the software contains over 5,000 images (32x32 and 16x16 pixels).
Each image is in six different styles, so totally the software equals to contain over 30,000 images.
Images can be copied to clipboard for pasting by other applications (such as Photo-shop, Corel-draw).
Images also can be saved as files (gif, jpeg, bitmap etc).
All images can be resampled from 1x1 to 96x96 pixels.
Those images are classified as different categories, such as people, animal, system, equipment ...
don't miss it!
You can download from here
Thank you

You can use the Article submission wizard[^] to submit it to the site automatically. As it will appear on the site immediately, please take some time to prepare your article.
If you don't plan on posting full source code, make sure to post in in the "free tools" section. Good luck

Hi,
I have a XML file which needs to be first validated using a DTD and then parsed to get values & properties associated with tags.
I am using Visual Studio's VC++ 6.0 to write my code. Is anyone aware of any reference or tutorial which would help me learn the same.
Thanks You!!
Regards

I use Xerces[^] to do just that. Imho, it's much faster than MSXML.
