VC中如何从字符串中分离文件名与路径

CString strPath;
int n=m_strOriFileName.ReverseFind('\\')+1;
strPath=m_strOriFileName.Left(n);

CString strFile;
int n=m_strUntFileName.GetLength()-m_strOriFileName.ReverseFind('\\')-1;
strFile=m_strOriFileName.Right(n);

CString strFileType;
int n=m_strUntFileName.GetLength()-m_strOriFileName.ReverseFind('.')-1;
strFileType=m_strOriFileName.Right(n);
