如何把CFile对象定义成成员变量

[yangwl]

我定义了一个类MdsDDBridge，MdsDDBridge里定义了一个成员变量是CFile类型的：
CFile file1;
然后再构造函数里加了代码：file1=new CFile();
当MdsDDBridge a=new MdsDDBridge();时报错如下：

Compiling...
error C2440: 'initializing' : cannot convert from 'class MdsDDBridge *' to 'class MdsDDBridge'
No constructor could take the source type, or constructor overload resolution was ambiguous

MdsDDBridge.cpp
error C2582: 'CFile' : 'operator =' function is unavailable

这样定义CFile *m_pFile;
然后m_pFile=new CFile;

还有一个错：

MdsDDBridge a=new MdsDDBridge();


error C2440: 'initializing' : cannot convert from 'class MdsDDBridge *' to 'class MdsDDBridge'
No constructor could take the source type, or constructor overload resolution was ambiguous

MdsDDBridge::MdsDDBridge()
{
DSN="oradb9i";
UserName="testuser";
PassWord="testuser";
DataBase="Oracle";
System="Oraclesystem";
XmlFileName="D:\\test.txt";
file1=new CFile;

}

MdsDDBridge* a=new MdsDDBridge();

同意楼上。

CFile *m_pFile;
m_pFile=new CFile;

MdsDDBridge* a=new MdsDDBridge();
