防止Microsoft Excel打开xlsx文件. [英] Prevent microsoft excel from opening xlsx file.

问题描述

我有一个带有图表，表格和公式的xlsx文件.最初，该文件是在Microsoft Excel 2007中创建的.
有没有一种方法可以防止文件被Microsoft Excel打开?也许是因为我弄乱了文件头，或者是我写了一个自定义包装程序，甚至是自定义加密它?
加密/包装后，xlsx文件应该是Microsoft Excel无法识别的文件，可能带有自定义扩展名.

打开xlsx文件的唯一方法是通过我的C#程序将其打开，该程序将对其解密或解包，然后使用DSO成帧器在C#中也将其显示.解密/解包和显示它的过程没有在硬盘上保存任何xlsx文件.

如果有办法，有人可以指出我正确的方向吗?
我的多阶段程序的第一阶段是对其进行加密/包装(不确定它是否是正确的术语).
我只知道如何描述我打算做的事情，但不知道它的正确用语，因此不确定如何甚至开始在google中搜索它.

请指教.谢谢.

Hi, I''ve got an xlsx file with charts, tables, formulas. Initially, the file was created in Microsoft Excel 2007.

Is there a way for me to prevent the file from being opened by Microsoft Excel? Maybe by me messing with the file header or maybe me writing a custom wrapper or even custom encrypt it?
After encrypting/wrapping it, the xlsx file should be a file that is not recognized by Microsoft Excel, maybe with a custom extension.

The only way to open the xlsx file is to open it through my C# program, which decrypt or unwrap it and then displaying it also in C# by using DSO framer. The decrypting/unwrapping and displaying it is done without any xlsx file saved on the hard disk.

If there is a way, can somebody please point me to the right direction?
The first phase in my multi-phase program is to encrypt/wrap it (not sure if it is the right terminology or not).
I only know how to describe what I plan to do but don''t know what it the right term for it so am not sure how to even start searching for it in google.

Please advise. Thanks.
