啥问题？我直接复制过来编译后提示有错误，不过我把 case 4://从文件中搜索作者所有图书 char writer[12];这里的char writer[12];还有case 6://删除所找的图书   BOOK *pre; 这里的BOOK *pre;放到函数开头定义就编译通过了；具体功能没有调试，不过感觉界面不太友好，中间那个大方块是做什么用的？

谢谢你帮我改错。
中间的框是用来显示查找结果的，可以用不上。程序只能存入图书信息，isbn查询图书程序就崩溃了，以后的步骤就实现不了了。
能否帮我看一下后面的程序功能为什么实现不了呢？

case 0://初始化链表
    head.next=NULL;
    tail=&head;
这两句初始化代码最好放到定义head后就自动完全，不要由用户操作来完成。

中间查找结果的框，通常的操作可以这样：mhWnd是这个框（edit）的句柄。

//设置可以输入最大字符数，nMaxSize = 0 时无限制。
void _SetMaxSize(UINT nMaxSize)
{
    SendMessage(mhWnd, EM_SETLIMITTEXT, (WPARAM)nMaxSize, (LPARAM)0);
}

//清除编辑框内容
void _Clear()
{
    SetWindowText(mhWnd, NULL);
}

//在尾部添加一行
void _AddLine(const char* szText)
{
    SendMessage(mhWnd, EM_SETSEL, (WPARAM)-1, (LPARAM)0);           //选择到尾
    SendMessage(mhWnd, EM_REPLACESEL, 0, (LPARAM)szText);           //添加一行
    SendMessage(mhWnd, EM_SETSEL, (WPARAM)-1, (LPARAM)0);
    SendMessage(mhWnd, EM_REPLACESEL, 0, (LPARAM)(TEXT("\r\n")));   //添加回车换行符
}

//返回某行（dwRow）的文本
char* _GetLine(const DWORD dwRow)
{
    // 使用 EM_GETLINE 时要注意：
    // 1、在存放数据缓冲区(szBuff)的首字节写入最大的字符数值（MaxStrLen）
    // 2、执行 SendMessage 读取数据，返回取得读出的字符串长(nLen)
    // 3、在读出的字符串尾部添加结束符'\0'

    //EM_FMTLINES wParam= TRUE或FALSE ;Param=0 决定是否在取回的文本宇串中包含软回车字符

    *((LPWORD)szBuff) = MaxStrLen;
    int nLen = SendMessage(mhWnd, EM_GETLINE, (WPARAM)dwRow, (LPARAM)szBuff);
    szBuff[nLen] = '\0';    //在字符串尾添加结束符
    return szBuff;
}

//返回编辑框文本总行数
DWORD _GetLineCount()
{
    return SendMessage(mhWnd, EM_GETLINECOUNT, 0, 0);
}

中间查找结果框类型设置：
WS_CHILD | WS_VISIBLE | WS_HSCROLL | WS_VSCROLL | WS_BORDER | ES_MULTILINE | ES_AUTOVSCROLL | ES_AUTOHSCROLL | ES_LEFT;

懂了，不甚感谢！

不客气，不过不好意思，链表的相关知识我还不是很懂，可能需要其他朋友多多帮你了
