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. Smile | :)

Came to my mind this is, in Java(I've much familiar than C++) using a single line I can get this. Wink | ;)

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)...

// Note: This header file contains useful classes that are documented only
//  in the MFC Technical Notes.  These classes may change from version to
//  version, so be prepared to change your code accordingly if you utilize
//  this header.  In the future, commonly used portions of this header

about FAT32 file name and directory name length limit

HOW WHAT12-Jun-08 17:06

HOW WHAT

12-Jun-08 17:06

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,
FAT Long directory Entries 's LDIR_Ord cannot use also???

How many long file name or long directory name can use FAT Long directory Entries structureS?

sorry my bad english.

Thanks.

How to eliminate the Help Created by the Wizzard in MFC and enable your own HTML Hep Workshop file already created.

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?

Could you elaborate? Do you want to prevent multiple copies of the software on the same machine?
