Excel文件上的加密/解密 [英] Encryption/Decryption on Excel File

问题描述

大家好，  
我要开发一个从数据库搜索的小型软件.由于数据很小，我想到了使用EXCEL，但是现在我的问题是当我出售该软件时，我不想用户可以查看Excel文件和数据.

我申请的目的是搜索年份产品的ID ...
好数据由Product ID和Year组成.只有两列...
由于它是一个小型应用程序，因此我不希望使用SQL这样的大型数据库.
解决方案

保持数据在excel中不是一个好主意.您可能要检查文件系统数据库，例如SQL lite或SQL CE.

客户是否还需要安装此文件以执行应用程序吗?在这种情况下，许多客户都不知道这些东西... p>

还如何使用SQL Lite保护数据?

Hi All, 
I am going to develop a small software which searches from the database. 
Since the data is small, I thought of using EXCEL, but now my problem is when I sell the software, I dont want the users to view the Excel file and data.

My purpose of application is to search the year of a product from its ID...
User enters the product ID and the application returns the year...
Well the data consists of Product ID and Year... only two columns...
But the rows may extend to 5000. 
Since its a small application I dont want any big databases like SQL .
But my data has to be secured.
