Yes. It's the right way. but just to generalize:
int items = sizeof(numbers)/sizeof(numbers[0]);
Somethings seem HARD to do, until we know how to do them.

That's cool, isn't it. No need to worry about that array type.
I appreciate your help all the time...

Yes this is correct but since this is possible only for fixed size arrays I will recommend this
const int ITEMS = 3;
int numbers[ITEMS];

Ya, quite similar way I following normally.
Why I ask that question is, I like to pass less number of arguments to methods. Say just I can pass the array and if I want I can find number of elements on it. I think you cleared what I say.
I appreciate your help all the time...

Thats is possible but it is more error prone because the function cannot know if array was fixed size or dynamically allocated. So if someones passes a dynamically allocated array then size array using this method will always be 1. So you have to be very careful that about calling such function.

I'm confused. At the time of passing the array, array size(number of elements) are fixed. I'm not going to use like in a looping function to pass. In such a case as you said I'm in a big trouble.
Whats your comments.
I appreciate your help all the time...

Okay I might be wrong but I think when you said you don't want to pass size of array as an argument, this is what you want to do.
void foo(int* array)
{
int x = sizeof(array)/sizeof(array[0]);
//
// Process array here.
//
}
So I was wrong in other post and the problem is that x will always be 1.

If you created the array yourself, you now its size. So I don't really understand the point. Could explain why you want to calculate the size instead of just using the same number you put in your array (if you defined it as a constant for example) ?
On a side note, you might want to look at existing container classes like std::list or std::vector.

Just fine, as you said I feel that vectors are specially useful than arrays. I just try to find it.
Came to my mind this is, in Java(I've much familiar than C++) using a single line I can get this.
I appreciate your help all the time...

Recent Platform SDKs have a _countof macro that you can use instead of defining your own.

Hi all.
Need some help. I'm not long in MFC.
How to get size of dialog in template?
I'm deriving from CFormView and I need to know what is the size of dialog in template.
I can do this before or after window creation, but I don't know how in both times.
Thanks

You can use CDialogTemplate member functions GetSizeInDialogUnits and GetSizeInPixels.
Here is a note from MS on this class' parent file (afxpriv.h)...

in winxp, the directory name length limit is 244
in win98, the directory name length limit is 250
why isn't 255? why file name length limit is 255?
in FAT32 file system, FAT directory structure's DIR_Name cannot use 0x22, 0x2a, 0x2b,0x2c,0x2e,0x2f,0x3a,0x3b,0x3c,0x3d,0x3e,0x3f,0x5b,0x5c,0x5d,0x7c,

Hi,I finished Audio Capture and Receive with directsound.There is a netmeeting, I use a thread to receive a client data and decompress separately .
Now I use G729a.lib(got it from codeproject) to decompress,but It can not decompress multiply channels at the same time.
Could you send me Audio Compress code and instruction?
Thanks a lot.

In my program I selected Context Help and MFC gladly included the help mecahnism, but I have found it easily to created my HTML Help Files using HTML Help Workshop; which I have done. But I can't fiquire out how to get my program to forget the Wizzard's Help file and accept mine instead. I've seached MSDN and they just tell you how to create it in HTML Workshop, and if you have VS 6.0 They show how to include it in your program. But nothing on VS2008. Anybody know How?
Help!
