如何用vc把图片读取成16进制字符串

怎么用vc把图片读取成16进制字符串
怎么用vc把图片读取成16进制字符串, （不是BS64编码或别的）
我想在RTF中直接写入图片信息，需要把图片读取成16进制字符串，请高手帮忙

------解决方案--------------------
直接%02X编码，每2个字符代表一个字节。
不过RTF中这样出来的不是图片
------解决方案--------------------
BYTE *buff=NULL;
CFile file;
file.Open(...);
int nlen=file.GetLenth();
buff=new BYTE[nlen+1];
file.read(buff,nlen+1);
file.SeeKto(位图中数据开始的地方)
file.Read(buff,FILELEN)；
------解决方案--------------------
从msdn上改写

C/C++ code

#include <stdio.h>

void main( void )
{
   FILE *stream;
   char list[3000];
   int  i, numread, numwritten;

  
   if( (stream = fopen( "fread.bmp", "rb" )) != NULL )
   {
      int len = _filelength(_fileno(stream));
      numread = fread( list, sizeof( char ), len, stream );
      printf( "Number of items read = %d\n", numread );
      printf( "Contents of buffer = %.25s\n", list );
      fclose( stream );
   }
   else
      printf( "File could not be opened\n" );
}
