View 1 RepliesGet Rid Of A Blink At The Start Of A Small Program?
Jan 25, 2011I have been trying, without success, to get rid of a �Blink� at the start of a small program.
My program opens with a title page (Form2, which is visible at 100% Opacity) that I want to fade after a few seconds, this works fine except that at the first reduction of opacity, Timer1's first 'Tick', the whole of Form2 blacks out for a moment. (Blinks)
I have a short demo program to show what I mean but don�t think I can attach it to this question. The code is shown here but I don�t know how to include Form1 and Form2. They are very simple however, they�re both Size 1000,600
Form1 has a single Button (Exit) and a Timer; Form2 has a full-size photo as background.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I developed the code on a XP machine, but I also get the same 'Blink' on my Win. 7 Pro machine.
Using A Timer To Blink Multiple Buttons?
Oct 15, 2009i am working on an alarm system software, i am required to blink buttons whenever an alert SMS is received by my gsm modem, after checking for its authentication with the database. The buttons represents the individual units of houses that are armed with a hardware whereby whenever an alarm is triggered, the hardware sends a alert SMS which is received by my gsm modem. The unit under alert represented by the button will start blinking to show that its under alert, when clicked, it will stop blinking to show that the alert is acknowledged. But now i am facing a situation whereby when the second alert comes in, the first alert will be overwritten by it, which is not what i wanted, i want it to be like both buttons will be blinking, not overwritten. The buttons are all created when the program is running, with its text referred to the database. I have placed a timer to do all the blinking. The timer will start after the checking for authentication.

View 2 RepliesHow To Create An On-screen Shape (circle) That Has A Fill Color, Which Will Blink Every X Seconds
Jun 8, 2011I need to create an on-screen shape (circle) that has a fill color, which will blink every X seconds (go from fill color, to white, back to fill color). This is trivial to do...BUT... i want to do it in my own class, so that I can instantiate it numerous times passing it unique coordinates for each instantiation.
How do I do it? Can a class have its own "timer control" in it independent from the form? How would I draw a shape from a class?

View 1 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.

So that, this will require a on screen keyboard in order to type the username and password. In this case, I do not want to use external OSK (on screen keyboard), what I want is to create some numerik numbers or letters on my form1 with buttons and then type it on the URL.
