I have written an article on dynamic shielding Control Alt delete (http://blog.9cbs.net/jiangsheng/archive/2003/11/09/3789.aspx). After a few months, I sent the English revision of the article in CodeProject (http://www.codeproject.com/UserItems/preventclose.asp). But I didn't find the reason why the code collapsed in the debug environment. After a long time, I saw that Antonio Feija kept writing this code in a recently published article, and added some comments to the problem that the compiler settings may occur. I think this article is also very useful to my article's readers, so I am preparing to add a link to his article in my article.
Article introduction:
Antonio Feijao has studied for a long time on restricting user access desktops and applications. Although he finally did not use the techniques described in the text, he decided to publish the code collected during the research process for the possible user reference. He did not declare the author of the code, and he declared the author of the contact code as much as possible.
