Hi, I have to read a unicode file using Readfile api of MSDNhttp://msdn.microsoft.com/en-us/library/windows/desktop/aa365467(v=vs.85).aspx[^].

C++

char*	pBuf = NULL;
....
pBuf = (char*)new char[ dwFileSize+1 ];
bResult = ::ReadFile( hFile, pBuf, dwFileSize, &br, NULL );

But it is coming garbage value in pBuf?

Any Idea how to solve this. Above code fine for Multibyte files...

NOTE: Please comment / ans if you know solution.

Solution 1

You should properly interpret the file content. Richard's trip might be helpful: Handling simple text files in C/C++[^].

Solution 2

ReadFile as far as i know is not concerned about unicode, it just reads some amount of data from stream and returns to you. So now you need to interpret them.
there are apis to convert to unicode and back. (like MultiByteToWildChar and Wildchar..ToByte)
