C# DLL To Read In Java (Biometric Finger Print)
Jul 19, 2014My Personal Researches on this topic was ::
1) Use socket programming (i was able to connect to that ip and port but of no use? how to get data ??)
2) A lot of forums suggest the JNI or JNA way.. which i tried out and accomplished a connection to the port.
But the problem was the appoarch i used in JNA which only supports the loading of C/C++ dll files... not C# dll.... the BioMetric Finger Print device is coded in C#...

View Replies View RelatedJava For Data Carving - How To Read Any Of Known Digital Forensics Image
Sep 26, 2014I am looking to do it on data carving which is a technique used in digital forensics to extract known file information from unstructered raw data.
So, Lets say I make a bit for bit image of a usb drive that has some deleted images on it, jpeg maybe.
I can still recover this file by locating its header and footer information as its raw data is still on the drive after it has been deleted.
I would like to build a java application to automate this task. My problem is I dont know how to read any of the known digital forensics image (bit for bit copy of the driv) formats such as aff, e01 or raw dd.
Is it possible for me to read bytes from a raw data file in java, maybe search that file for the bytes I need and pull them out of there, perhaps to an array or something ??
I was thinking, if I could get all the raw data into a binary file in java it might be easier to work from there. What I really need is to get access to those bytes. If I could even write them all out to a text file, Id have something to work with.
Digital Signage System
Jul 1, 2014I am going to try and write a server-client based system.The server will be the design of what I want (e.g: daily advertisements that will be displayed on big monitors connected to the client, with like a slideshow looping). The client will just be receiving information from the server and not doing anything with it except displaying it and perhaps a networking element of the client reporting back to the server if the connection is dropped etc. The administrator can use the server to change the look of the advertisement.
I need the server to PUSH OUT to the client computers.I am on a networking degree so there has to be some elements to networking connections going on and programming is not my strong point. Would I write the server and clients in Java or another program? Will there need to be a "middle" program such as a web server?
JSF :: How To Implement Finger Printing System In Web Application
May 9, 2014I'm currently meddling with javaScript in order to implement a fingerPrinting system in my web application. I've developed the following example in which I can get all the necessarily data:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets">
[Code] ....
Which works correctly.
So when I tried to run it in the following page:
<?xml version='1.0' encoding='UTF-8' ?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<h:head>
<title>SET - Simulador Econômico Tendências</title>
[Code] .....
It simply won't work!
The function faz() is called and only the first "alert" popup is called, the second one which should show what is returned by dadosDaTela() isn't generated, why is that?
JavaFX 2.0 :: Two Finger Gesture Results In Touch Point Sequence
Sep 2, 2014I'm trying to implement a two finger gesture to move a control for a touch screen. However simply touching the screen with two fingers will generate several events that jump all over the place. This here is the code:
import javafx.application.Application;
import javafx.geometry.Point2D;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
[Code] ....
The log output looks something like this:
Two finger move pressed
First layout: 100.0, 100.0
Move by 94.0, 209.0 event set=4
Move by 1.0, 0.0 event set=5
Move by 95.0, 208.0 event set=6
Move by 1.0, 1.0 event set=8
Move by 96.0, 208.0 event set=11
Move by 219.0, 147.0 event set=11
Move by -121.0, 61.0 event set=13
I know that there is the possibility that I get multiple events with the same event set id. However this is not always the case. I would have expected to get one for each of the finger in the gesture. Why is that? As I understand the difference between changing the layout coordinates and the transformation is, that with the transformation coordinates, the bounds in parent changes, but not the bounds itself.
I'm not entirely clear on what effect this has, especially as I will also have the zoom and rotate gesture on the component. Which one is the better choice to change?To my understanding the coordinates of the touchpoint are relative to the parent component. In this case the layout coordinates of the rectangle. This would mean that I have to calculate the delta of the touch point in the onTouchMoved to the touch point of onTouchPressed.
This would get me the vector the rectangle moved.In the above example I use the main touch point of the two touchpoints of the event. As I understand it this should always be the same one. The correct way would be to calculate the geometric mean of the two points and use that, but that has the same effect. Simplifying the above example to one touch point only shows the same jumping behavior.

Java Online Applet For Survey
Nov 2, 2014For a project I have to create an online survey, I cannot use a per-made online survey system because I have really specific needs that no pre-made system can satisfy, so my idea would be to create it in java and store the data in some simple text file, which are fairly easy to work with in java. My question is, is it possible, and if yes how difficult is it, to put the entire thing online? What worries me isn't putting the applet itself online, but the text files that should collect the data, I already have the website to host it.

Root Function In Java Applet
May 12, 2014I like to know how to write root function in java applet. I know it in java function. Ex:
import java.lang.*;
public class Maths {
public static void main(String[] args) {
// get two double numbers numbers
double x = 9;
double y = 25;
// print the square root of these doubles
System.out.println("Math.sqrt(" + x + ")=" + Math.sqrt(x));
System.out.println("Math.sqrt(" + y + ")=" + Math.sqrt(y));
}
}
working fine. but If I tried in applet it's not working. Ex:
evap_trans = 0.0135 * SRAD * ( TMEAN + 17.78) * Math.sqrt(TMAX - TMIN);
If I execute above said formulae with out "Math.sqrt" results are ok. If I used then results shows ZERO.

Java Applet - Background Color Is Not Being Set
Nov 23, 2014I am trying to go about making this applet a bit different then normal. The issue I am having is it is drawing an applet but, not the right dimensions, it's able to be resized, lastly the background color is not being set. I mean, I suppose I could call paint() and just draw it out but, I read that I could make the applet pop out to the dimensions I would like. None of this is working sadly.

my exact question is can I rewrite the applet to make a pop out window and should I just call paint()?

Activating Inverse Button On Sample Java Applet
Dec 10, 2014Nearly all of hte sample Java Applet is pre-made by the teacher. I'm running into the issue where, if I use the string arithmetic inverse method provided by the textbook, it refuses to recognize variables such as s1, s2, and i. So I'm now trying to use stringbuilder, and running into a similar issue. It doesn't recognize hte symbol "buffer". Under the "else if ( e.getSource() == inverseStr ) {" is where my code starts. The "Your Code Here" was put there by the teacher, and I'm just using it as an easy way to create blank lines if I delete a method that isn't working for me in the above section.

Generic RPG Game - Java Applet When Adding Subroutine

The issue I am having right now is in my Class I have a subroutine (think that is the correct term) that is basically set up to hold a series of Print Statements.

Yet, when I run the applet it just pops up the Applet blank and gives me a long list of errors and I really don't understand when they mean.
