BOOL CopyFile( LPCTSTR lpExistingFileName, // pointer to name of an existing file LPCTSTR lpNewFileName, // pointer to filename to copy to BOOL bFailIfExists // flag for operation if file exists ); 当中各參数的意义: LPCTSTR lpExistingFileName, // 你要拷贝的源文件名称 LPCTSTR lpNewFileName, // 你要拷贝的目标文件名称 BOOL bFailIfExists // 假设目标已经存在,不拷贝(True)并返回False,覆盖目标(false) 如: //复制文件c:\log.txt到d:\log.txt,假设D:\log.txt已经存在,就覆盖 CopyFile("c:\\log.txt","d:\\log.txt",false);
