本来是写控制台的。控制台的代码也放一起了。
我想知道为什么用控制台调用Searche函数读文件数据的时候没问题
我想做界面写的EGet函数读文件数据的时候总是读不到正确的数据。
困扰了我很久了。新手写得有的乱。
希望有大虾帮看看。谢谢了。

我給你advice你， 不要post那麼多的code上來，because no one wants to read such a long code.
I suggest you 可以先自己分析，把核心比較少的部份提出來，比較efficient。

file.seekg(indexTable[j].positiong, ios::beg);
pStaff.Read(file);

file干吗传参带入还写成全局的，C++风格，封装文件描述符企不更好，
