Disable ALT F4

[jazzyjeff]

Before anyway replies with an RFTM message, I have read the documents and understand the answer to my question.

I would like to create a program that will stop students at my school from exiting out with the ALT F4 shortcut. I was hoping to use the HotKeySet command, but after it didn't work and I did some reading up I have found that disabling the use of any command with the ALT key in is prohibited.

Firstly, is there a way to get around this using another command? I have searched for a long time, so I feel like I know the answer to that question.

Secondly, I feel like another option should be added to the HotKeySet function. If disabling the ALT key is a no go, can the function be given an option to disable the shortcut if any key specified is used i.e. {ALT}{F4} the alt is out of the question, but because F4 is listed this would stop the use of it.

This would be useful for many people despite the pitfuls that it could have for some people.

Thanks

Jeff

I doubt its the alt or F4 on its own that are the problem, its the combination of the 2 maybe.

Its a windows thing.

I googled around a bit, and there are methods of doing what you have in mind with code.

Thank you for your responses. After thoroughly reading through the help files, I found out how to disable this in AutoIT.

You mind sharing how or where you found the ability to disable the Alt+F4 command?

Sadly found out that SteadyState has been discontinued recently. It's still out there for download though. And this article also lists nice alternatives:

Mandar's solution works really well, as long as it is either the only script is running that disables Alt-F4, or is the first run.

If someone is feeling ambitious, maybe the following could be translated into AI from VB6:

I've had too long and brain-frying a weekend to focus on right now.

--- Edit ---

This might also be a solution (again from VB6)

// claim your program is a password protected screen saver, this disables ctrl-alt-del, alt-tab and ctrl+esc
int old;
SystemParametersInfo(SPI_SCREENSAVERRUNNING,true,(void*)&old,0);
