cannot convert parameter from 'class CStdioFile' to 'class CStdioFile'

 void CLhstrackingcvDoc::SendData(CStdioFile File)

{

     File.WriteString(m_strSend);
     File.WriteString("\n");

}

调用：

 CStdioFile myFile;

 char* pszFileName="C:\\myfile.txt";

 CFileException fileException;

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

SendData(myFile);

 

提示：SendData cannot convert parameter 1 from 'class CStdioFile' to 'class CStdioFile'

解决办法：

void CLhstrackingcvDoc::SendData(CStdioFile &File)

{

     File.WriteString(m_strSend);
     File.WriteString("\n");

}
