I have written an access control program in delphi 16 using SetSysModalWindow to lock out the mouse and alt tab etc. Of course you can still use ctrl-alt-del to shut it down in 95.
I am now trying to redo it in delphi 2 and make it more secure. I have considered doing thunking to make SetSysModalWindow work, but I'd like to stop the user ending the task with ctrl-alt-del. The program picks up username and password from my server app via TCP/IP.
Any suggestions? Device driver maybe?
