wdm过滤器驱动程序与win32控制台应用程序交互 [英] wdm filter driver interact with win32 console application

问题描述

我想开发一个程序来限制用密码访问u盘。目前，我有两个想法。

I want to develop a program to limit access to u-disk with password. at present, I have two ideas.

1.用户插入U盘后，过滤器驱动程序调用控制台应用程序以要求输入密码。

1.after the user plugs in the u-disk, the filter driver call the console app to require the password.

2.用户插入U盘后，没有任何反应。用户必须打开控制台应用程序，输入密码，然后使用U盘。

2.after the user plugs in the u-disk, nothing happens. The user has to open the console app, input the password, and use the u-disk.

任何人都可以告诉我哪种方式更容易，并使用什么技术或机制来做到这一点？谢谢！

can anyone tell me which way is easier, and use what technique or mechanism to do it? thanks!

推荐答案

无论哪种方式都有效，但没有驱动程序弹出控制台（或任何其他类型）应用程序的方式。通常对于＃1，你有一个在后台运行的总是运行的用户代理没有显示ui，监听设备到达通知，
从你的过滤器（WMI，一个笔下的io等）监听某些内容并显示ui需要的时候。选择＃2不那么复杂，但要求用户知道先行做什么

either way works, but there is no way for a driver to pop up a console (or any other type of) application. typically for #1 you have an always running user agent running in the background that is not displaying ui, listens for a device arrival notification, listens for something from your filter (WMI, a pended io, etc) and shows ui when needed. choice #2 is less complex, but requires the user to know what to do a priori
