Both options produced the same error (C2011) when comments removed.
This is a Microsoft file, so should we be modifing it?

wow, absolutely not !!!
i thought it was one of your when you told you commented on... never do this !!!
however, don't you create a struct in your files that is in fact already defined in the library ? if so, change your structure identifier...

I have searched my project to ensure that no types/structures have the name stat.
None present.
Still confused, but thanks for your help.
PS Still have the Visual Studo file with my commented out section.

but what about _stat as the compiler says ?

The result of the search as follows:-
Find all "_stat ", Subfolders, Find Results 1, Entire Solution, "*.*"<br />
C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\wchar.h(421):struct _stat {<br />
C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\wchar.h(493):_CRTIMP int __cdecl _wstat(const wchar_t *, struct _stat *);<br />
Total found: 2 Matching files: 1 Total files searched: 101
Are they any tools hidden away in Visual Studio to help wit this problem?

Try to use /P compile key it will produce *.i file in which you can find where is was already defined.

Hi guys
I have an application which reads from an Excel sheet. The application reads from the sheet properly till a specific row is reached. After that the next row is not read properly and the subsequent read returns blank data.
Please help me with suggestions...

i created a buffer,
how do i reduce the size of lpBuffer without losing the initial items in it.
LPBYTE lpBuffer;
lpBuffer = new BYTE[5000];
lpBuffer[0] = 'h';
lpBuffer[1] = 'i';
easiest way to make lpBuffer smaller size?!
Any help is appreciated thanks!

Hello
You can try to use realloc(lpBuffer, new_size)

No! The original buffer was allocated with new.

So ? Does not the new equal to malloc(), and delete equal to free() ?

no, not at all !!!
new and delete are re-entring functions, while C ones (malloc, realloc, free) aren't.

Yes, you are right. I found the answer. I just was confused by a small sample using MFC - it was looking that they are the same. But they are not.
Thanx !

I guess Andrew mean to use maalloc(...) then realloc(...) no "new" shoud be used in this case.

you could use list<> or vector<>.
otherwise, the only way is to create a new array (using new operator, the length you like), then copy the datas you want to preserve during the "resize operation", then delete the old array...

If possible, use stack memory instead of allocating. Then you don't have to care about size.
Don't try it, just do it!

Why do you want to decrease the size of the buffer? You know that there are no easy ways to manipulate the size of an array! The only way to change the size of an array is to create a complete new one with the size you want and copy all the items you can from the old array..
As other users pointed out, you can use a std::vector or some other collection class.

Something like:
LPBYTE lpBuffer2 = new BYTE[1000];
memcpy(lpBuffer2, lpBuffer, 2 * sizeof(BYTE));
delete [] lpBuffer2; The other way is to not make it too big in the first place. Lastly, even if you ended up just using 2 of the 5000 bytes, that's not a big deal in the overall scheme of things.

Strange.
Declare and array of 1000 bytes, then copy 2 bytes from the old array to the new array.

Indeed, but since the OP did not specify what size he wanted the array "shrunk" to, I just pulled a smaller number from the sky.

:-DYeh; I thought about that after the fact.
Normaly I just substitute the numbers with something like new_array_size. Because it is closer to how we would actually write it.

Yes, I've done that too, only to be asked shortly afterwards, "What is this new_array_size thing and how do I use it?"

Ya first of all just like to thank everyone for helping out
cant use Cbytes for the application
and ya the buffer doesnt get filled by only 2... its filled by user specified items. So ill probably use the memcpy function that DavidCrow suggested, the buffer will be reduced by checking the amount the user filled.
Was hoping i didnt need to create another buffer array but seems like best solution is to cpy it so far.
Thanks,
Mepho
