Javascript for blocking keystrokes

[jaydeep16]

Hi

Can anyone help me with javascript for blocking Ctrl-N keystroke. I want to ensure that user will not be able to open a new IE window by pressing Ctrl-N

Why don't you want to prevent people from opening up a new IE window ¿

Did you search Google first? A simple search returned the following: http://forums.devarticles.com/javasc...ning-7531.html

Just a small clarification...Even though you can block keystrokes, you cannot block the menu nor context menu from providing you with new window options.

If you want to have only one instance of your application per user, then you can set a flag in your database when a user logs in, and remove that flag when he logs out. When he tries to log in , you check if the flag is set or not. If the flag is set, you branch the user to a default screen saying "you are already connected".
