Question

class CMyFile
{
int a;
wchar_t str[10];
public:
CMyFile()
{
a = 12;
wcscpy(str, L”ddddd”);
}
};

i am writing in following way
CMyFile l_temp;

CFile myFile;
CFileException fileException;

if ( !myFile.Open( pszFileName, CFile::modeCreate |   
    CFile::modeReadWrite, &fileException ) )
{
    TRACE( L"Can't open file %s, error = %u\n",
        pszFileName, fileException.m_cause );
}
else
{
    myFile.Write((wchar_t*)&l_temp,sizeof(CMyFile));
    myFile.Close();
    }

but when i reading it is not reading correc t values
reading code is given below
class CMyFile
{
int a;
//abc obj;
wchar_t str[10];
public:
CMyFile()
{
//a = 12;
//wcscpy(str, L”ddddd”);
}
};

CMyFile l_temp;

CFile myFile;
CFileException fileException;

if ( !myFile.Open( pszFileName, CFile::modeCreate |   
    CFile::modeReadWrite, &fileException ) )
{
    TRACE( L"Can't open file %s, error = %u\n",
        pszFileName, fileException.m_cause );
}
else
{

    myFile.Read((wchar_t*)&l_temp,sizeof(CMyFile));//not reading correctly
    myFile.Close();
    }
