Sep 12, 2011To start off with, I will say that I have tried ENDLESS attempts to surpress/capture/stop the actual sleep keystroke.

The code cannot create registry keys because that requires admin privilege's.

View 1 RepliesScript To Disable Keyboard And Mouse
Dec 25, 2011I am kind of amazed that there is no answer to this anywhere and I mean anywhere. I am looking for a way to disable the keyboard (actually all input) on a computer. There are several threads about it but no one has ever posted any serious, working code. I know someone is going to inevitably ask "why would you want to do that"? Actually why I want to do it is immaterial but if you must know... I am playing with a "USB Keylock". When this USB Keylock is not present in the computer I want to disable the keyboard. When it is present I want to enable the keyboard.

View 4 RepliesMonitor Key Down And Disable "windows Key" On Keyboard
Aug 23, 2010How can I disable the windows button on the keyboard while my application is focused?
I'm having an endless problem with users accidentally pressing the windows key on the keyboard which causes the application to lose focus. They are capturing data, so when they finally realize that while they were typing nothing happened. They have to find the place where they lost focus and redo everything from there. This is very time consuming and as we are paying our data capturers by the hour this turns out to be an expensive flaw in the application.

View 2 RepliesGet A Key Pressed From The Keyboard?
Nov 7, 2010This may sound like a dumb question but I need to know. I know you can tell which keys are pressed on the keyboard but I like to know if I can do something.Ok, heres what I am trying to do. A user is in another program that is max on the screen. He has to press Print Screen to take a screenshot, but he got to min the screen he is in to paste the screenshot into paint. This causes slow loads on maxing that screen and sometimes crashs of the program. I already got the code done to check when the program is running and to capture the screenshot and save it. What I to do now is, find out while in the other program with my program running in the background, if the user has pushed the Print Screen button.

Anti-keylogging Keyboard?
Nov 19, 2009Are there any known sofware approaches to anti-keylogging,that defeat both hardware and hook based loggers? While I was thinking about my next article, and the current ones, something dawned on me, that I had started before but never got to finish.After doing some research I verified that an On-screen keyboards, avoids most if not all hardware loggers, but the consensus is that their messages can still be hooked and stolen.Well maybe not so fast....
However, in my sendkeys article,the program could identify which keys were sent by my module, versus some other source.I used the integer -11, in the getextrainfo param, so that in my hook, I could know to allow my simulated keys, and block others that may interfere. Works great. I just used -11 for the heck of it.So, the idea is that we don't have to use -11.A sequence of random numbers could be generated by the osk.This provides some anonimity, to start with.But, the clincher is that when our user keys are detected by our osk(ourself basically), we simply insert 0-5 random keys, flooding the enemy logger with useless information in the que. Bingo!Sure they logged your keys, but can they read em? Nah.
The zero through five would not be fixed, but fluxuating, so it's not equidistant.I just picked them so as not to over flood the que for no reason. That is enough to obsure the password being typed.

C# - Distinguish Between The Scanner And The Keyboard
Apr 12, 2011I have a barcode scanner connected to a PC that working with a c# program.now i want to distinguish between the scanner and the keyboard which one is sending data to my program.
somebody said this to me in another topic(but i can't do this yet): basically you can configure the scanner to send some characters that basically tell the computer "hi, it's me". When you see those characters in your input stream, you know the information is coming from the barcode scanner, not from something the user typed on the keyboard. Did you check the manual that came with your barcode scanner? It should have more information about this.
Capture All Keyboard Events?
Aug 9, 2010I've written an app with a simple textbox which attempts to identify a user from their typing habits (interval between key presses, duration key is held, time between key strokes ie a->s is quicker than a->v for some users, shorter for others depending on typing style). It's far from perfect but it does correctly identify moderate-large differences in style.I'm hoping to use this as a form of security monitor - If the typing style of the user doesn't fit a recognised pattern, report to a central server.
Of course, the next step in testing this is to begin to capture "regular" typing habits - ie when browsing, switching between apps, etc.What I can't figure out how to do is capture keyboard input for all applications (excluding the login/welcome screen, alternate desktops, etc. - I have no reason to parse that and there's probably not enough input to analyse anyway)Disclaimer: Yes, I know this comes dangerously close to writing a keylogger which is verboten but if I wanted to do that, I'd write a keyboard driver in C++ - I'm sure it would be far more streamlined and easier to obfuscate than a hulking .Net MSIL assembly. I have no doubt I'll be fending off "That's a keylogger" comments but I've hit a wall and need to ask somewhere.
