Dynamic blocking control + ALT + Delete (update)

I 've written an article about dynamic blocking of Control + ALT + Delete (http://blog.csdn.net/jiangsheng/archive/2003/11/09/3789.aspx ). A few months later I posted an English revision of the article on codeproject (http://www.codeproject.com/useritems/preventclose.asp ). However, I did not find the cause of code crash in the debugging environment. After a long time, I saw Antonio feijao rewrite this code with C in a recent article, and added some comments to illustrate possible problems with compiler settings. I think this article is also very useful to the readers of my article, so I am going to add a link to his article in my article.

Article introduction:

Antonio feijao has been studying limits on user access to desktops and applications for a long time. Although he did not use the technology described in the article, he decided to publish the code collected during the study for reference by possible users. He did not declare the author of the code, and he declared that he would try to contact the author of the Code.
