Java Forum / General / November 2006Block user input
Hello everyone, im trying to write an internet cafe program that locks machines when they are not in use. My program is going to work by displaying an image and blocking user input from both the mouse and the key-board?? Thats where the problemm lies, i don't know how to achieve this. I have tried implementing both the MouseListenter and KeyboardListener interfaces and consuming events in each but i don't think its working properly or not at all. Do listeners perform an action after an initial action takes place?? And if this is the case would it be to late to consume an action once it has already happened?? Also what component do i attach the listeners to for it to affect the whole system??

What would be wrong with using the normal screensaver, and configuring it so it requires a password? /Thomas  SignatureThe comp.lang.java.gui FAQ: http://gd.tuwien.ac.at/faqs/faqs-hierarchy/comp/comp.lang.java.gui/ ftp://ftp.cs.uu.nl/pub/NEWS.ANSWERS/computer-lang/java/gui/faq >> Hello everyone, im trying to write an internet cafe program that locks >> machines when they are not in use.

Typically, you want to be able to force-kick a customer after a certain period of time. E.g. the customer pays for 2 hours of usage, and after 2 hours, the customer should be locked out, with the option of purchasing more time. I don't think you can do this using Java. I don't think a Java program can block all input. In particular, CTRL-ALT-DEL or ALT-TAB might be difficult to block. - Oliver >>> Hello everyone, im trying to write an internet cafe program that locks >>> machines when they are not in use.

This is done in windows, by administrating user permissions, and doesn't have anything to do with java you just disallow user to change/do certain thing :D > - Oliver Thanks guys, and Carramba where might one find these user permissions?? Im not really a windows guy so im not to familiar with the file system. > >>> Hello everyone, im trying to write an internet cafe program that locks > >>> machines when they are not in use.

I don't think Java is the right tool for this job. /gordon Signature[ don't email me support questions or followups ] g o r d o n + n e w s @ b a l d e r 1 3 . s e Free MagazinesGet these publications absolutely FREE for up to 12 months.
