#include<...> means to search first tru a list of 'Standard' directories. You can edit or change that list through your Project/Settings options. At the time of writing the standard, the fear was that someone had his own working library and header file like say 'stdio.h', which at that time could have crashed some one's code when they took the standard on board. Hence the '<...>' is for 'standard' files.
NB, from an Old Hand: Use <...> ONLY for standard files , and "..." for ALL your own includes as a matter of form!
It eill save you heartache over time, untill you gain full understanding of how your compiler searches include directories.

Not yet.
It's ok in vc6.

I'll try vs2005 tomorrow.
Thanks all the same.

I hope you didn't uninstall VS 2008 just because your
controls didn't show up

Another reason is that it is bit slow and lack of a class wizard at least in the beta version.
I've tried to report the control problem to ms.

Does anyone know how to retrieve a Hard Disk Serial number from the Hardware.(i.e. one that corresponds(or is supposed to do so) with the label on the Device. (or, for that matter, any other number that identifies a machine.) I am trying to put together some licencing software. Is there any code about I can readlly use free in a small commercial app, whitout delving into too many details.
Happy New Year to All

Use Win32_PhysicalMedia class of WMI to get the hard disk serial number.

#include <fstream>
std::ifstream file("C:\\Temp\\hello.txt");

Without further info I do not realy understand your problem, but, the general procedure is:
Step 1. You should know the fully qualified name of the file you want to read i.e.: CString MyFile="C:\MyDirectory\MyData\DataFile.ext". If you type that as a string in your code(bad Idea, but not your immediate problem) you should type all backslashes double. i.e.:CString MyFile="C:\\MyDirectory\\MyData\\DataFile.ext".
Step 2;
You Open the file, and get a File Handle:
FILE* F =fopen(MyFile,"rb"); The "rb" means that you want to open the file for binary reading, (as opposed to Text Reading, which should be opened for reading with just "r")
Step 3: You find out how big the file is. You move the File Pointer to the End of the File, and ask where it is.
size_t CurPos=ftell(F);// Record the File Pointer
fseek(F,0,SEEK_END)
size_t FileSize=ftell(F);
fseek(F,CurPos,SEEK_SET);// Returns the FilePointer to where it was
Step 4:
Allocate a buffer to hold the File Contents
char* Buf=(char*)malloc(FileSize);
Step 5:
Ensure that there was enough free memory left to Allocate the Buffer
if(Buf==NULL) return ERR_OUT_OF_MEM;
Step 6:
Read the File into the Buffer
fread(Buf,FileSize,sizeof(char),F);
step 7:
Close the File. This is most important, Noone Else can work with the file while you have it open, Even yourself cannot open it a second time.
Step 8:
The contents of your file is now in Buf. Do with it as you like.
Step 9:
When You're done with it, you should 'free' Buf. Unlike say VB, C++ has NO garbage collection service. It is up to you to get rid of memory you no longer need.
