怎样将一个bmp分成127byte得块，然后再恢复成bmp？急事！！！

bmp是不知大小，但一点小于65535byte。我自己写了一个，但是10k的只能恢复到9.29k。请问原因何在？
CString m_name = "c:\\winnt\\zapotec.bmp";
CFile MyFile1,MyFile2;
if(!(MyFile1.Open(_T(m_name),CFile::modeRead)))
{
AfxMessageBox("Can't open file");
}
if(!(MyFile2.Open("11.bmp",CFile::modeWrite &brvbarCFile::modeCreate)))
{
AfxMessageBox("Can't creat file");
}
long Length = MyFile1.GetLength();
char pData[65535];
char *p;
p = pData;
MyFile1.Read((void *)pData,(UINT)Length);
char sData[127];
CString Data,rData;
long i,k;

7不能用CString，用64个字节循环读并且发送就行了。</length>
