Tell us why and maybe we'll be able to offer suggestions. Unless you are bent on having a for loop to read X bytes at a time until you reach SeekPos2, why not set up a buffer big enough to hold SeekPos2-SeekPos bytes and call Read() once?

CString str;
unsigned long k=10000;
str.format("%?",str);
Thanks

Use %lu
But str.format("%lu",k); not str

what about checking the CString documentation first ?
how ?
open msdn.com first and make a search on CString class members.
reach Format(), and there you go.
the harder part is for now. read what's there, and understand it !

that was a pretty stupid question. the guy already knows the syntax will be omething like %? but he is too lazy to search the exact form.
so, i'm as lazy as him...

How do you read the file? Can you show the code?
|
|
|
|
|
//m_Path=input path
//m_Path2=output path
fstream rfile(m_Path,ios::in|ios::binary);//input file
fstream wfile(m_Path2,ios::out|ios::binary);//output file
//SeekPos is a starting location from where i start reading.
//SeekPos is a ending location till that i read.
char buffer[200000];
for(SeekPos;SeekPos<=SeekPos2;SeekPos++)
{
//rfile.get(ch);//if i read as character wise.
//wfile.put(ch);
rfile.read(buffer,sizeof(buffer));read from buffer
wfile.write(buffer,sizeof(buffer));
wfile.flush();
rfile.flush();
}
rfile.close();
wfile.close();
i m using this code plz tell me

What a mess!

You're asking to read about 195 Kb from your file.
You need anyway to check for the failbit status after the reading operation.
vijaylaxmi wrote: wfile.write(buffer,sizeof(buffer));
You need to write (I suppose this is your requirement) only the effective number of bytes read.
And so on...

basicaly i want to read a audio file length of this file is not confirm it is any thing.
my aim is read this file in binary mode and write in any othe file.

You are reading the data of size 200000 bytes at a time, but SeekPos is incremented by 1. Why?
vijaylaxmi wrote: rfile.read(buffer,sizeof(buffer));read from buffer
wfile.write(buffer,sizeof(buffer));
Why? The read data may be less than the size of buffer when the reading is near to end.
So only the read bytes should be written, unless you are so sure about the read data size.

Why don't you search for a free tool to accomplish the task. Google is you best friend.

And how did you try to read?

//m_Path=input path
//m_Path2=output path
fstream rfile(m_Path,ios::in|ios::binary);//input file
fstream wfile(m_Path2,ios::out|ios::binary);//output file
//SeekPos is a starting location from where i start reading.
//SeekPos is a ending location till that i read.
char buffer[200000];
for(SeekPos;SeekPos<=SeekPos2;SeekPos++)
{
//rfile.get(ch);//if i read as character wise.
//wfile.put(ch);
rfile.read(buffer,sizeof(buffer));read from buffer
wfile.write(buffer,sizeof(buffer));
wfile.flush();
rfile.flush();
}
rfile.close();
wfile.close();

Maybe you should start with a less ambitious project until you learn about return values and such.
Have you considered something like:
std::istream i = rfile.read(buffer, sizeof(buffer));
wfile.write(buffer, i.gcount());
