Problems for final year project regarding jpanel to jpanel communication
Hi, I have some problems regarding the creation of a traffic simulator using Net beans. I have three classes for a frame and two panels, namely SimUI() which is the Frame class and TunnelPanel() which extends the panel that the road and traffic will be displayed. I have got so far only to encounter some problems regarding the event listeners which are placed in SIM UI() : The frame class. I want my buttons in one panel to paint objects which re in another panel. someone PLEASE help me as I dont have much time left. Here is my code: -
import java.awt.Color;
import java.awt.Event;
import java.awt.Graphics;
import javax.swing.JSlider;

public void paintRoad(Graphics g)I have already attempted to call the method from the mouseclick event listener in SIM UI:
TunnelPanel.paintRoad(Graphics g)but a compiler error reads cannot issue a static command or something like that: -

Hi everyone, I'm new here. In fact this is my first ever post in the SDN coummunity. I'm studying BIS and majoring in knowledge management. I'm also very very interested in enterprise 2.0
I started learning about SAP 4 months ago and since then I've been hooked. I don't know much and I'm not an expert like you all but I'm absolutely willing to learn, learn and learn some more.
I'll be starting my FYP soon and I was thinking of doing it using SAP/ABAP since I'm preparing to get certified and to have a career in an SAP related field after I graduate anyway.
Any ideas please? This lost ambitious soul would appreciate your help. Is it possible to do something not too complicated related to knowledge management or enterprise 2.0 with ABAP?
SAP is available in my university computer labs.
Thank you all in advance and my apologies if I'm posting this in the wrong place.Hi Edward. For a while I was starting to think nobody was going to reply.
SAP is indeed a huge and wide world. That's what makes it both interesting and challenging. We do get taught a basic course in ABAP at my university but that's about it. I'll be enrolling in it next semester. By the end of this year, I'll be hopefully sitting for an SAP certification. Meanwhile I'm reading a lot on SAP and also doing my 8 months internship in Alcatel-Lucent. My tasks are more business oriented rather than technical (something I'm glad about).
Why did I develop an interest in SAP? Well, since I was a little kid, I've always loved LEGOS. It seems like there are tons of SAP components and pieces that can be utilized in creative ways to solve problems and make business organization more efficient and effective. It all depends on how well the business process is analyzed, then adjusted to SAP's best practices and finally how the SAP components/modules (aka LEGOS in Amir's vocabulary) are put together.
I also have a deep interest in the application of technologies that facilitate creation of communities, better knowledge exchange and collaboration. I'm not that much interested in the technical aspects of the technologies themselves, since I don't really consider myself to be a programmer but rather their application. As for Enterprise 2.0, it's the next generation of KM tools and that's why I mentioned them together. Maybe KM 2.0 is a better term. Eh, poteto potato, tometo, tomato.
I don't have something solid in mind and there are some limitations. The SAP system in my campus isn't dynamic like how a real company's sytem would be. Plus I'm not sure how ABAP could be used to make applications within SAP. From my humble experience so far, it's mainly for report generation, kind of like how VBA and Macro aid in producing reports with Excel files.
What are ABAP's capabilities? I'm interested in making something like Blogtronix:

Im a Uni student&need help:JAVA Final Year Project: Undo Manager Problem
Hey all,
Im writing a Final Year Project and have minimal experience writing in JAVA.
It is an information visualisation assignment which involves reproducing code/text in a reduced format. Sort of to do with Line oriented statistics.
http://www.cc.gatech.edu/aristotle/Tools/tarantula/continuous.gif
This image will give you an idea of what im talking about.
Anyway, i need to know if its possible to get information about individual undos/edits from an undomanager.
Basically i need to be able to say, for example,
there are 12 undos
undo 12 occurs at line X
undo 11 occurs at line Y
etc etc
I need to be able to get this information without actually invoking the Undo last edit call.
Im bringing the Java undomanager tutorial home but from what ive read it seems like impossible?
Any and all help appreciated.
Regards,
PWhen I was at uni I had to implement that for the text area of an IDE. All I did was rip off the code from the Notepad.java that comes with the SDK.

I was design my final year project using LabVIEW 8.6 and now i state my design for someone to refer my project.
Thank You

Oscilloscope A.llb 166 KBDon't know if this is what you're searching for, and I don't know if there is such a function in LV 8.6, but I'm using LV 2010 and under DAQmx Pallete, you go to "Advanced Task Options", there is a function "Configure Output Buffer", in which you can configure the buffer size you want.

Ideas for my final year project
Hi evryone,
I'm a final year software engineering student,I'm looking for
dynamic,innovative final year project based on J2EE technologies.
I'll be looking forward for ideas/suggestions from the community members.Install Eclipse, tomcat, axis, logger, ajax...explore all and implement in your project.Why would you recommend those technologies?! Don't install or explore any of these until you decide WHAT you want to do. You match the tech to the requirement, not the other way around.

Need help on developing system as my final year project
hello everyone.
I would like to find someone who can guide me in developing a system for my final year project ( title:Event Correlation Analysis System).As i am not really good in programming i find it very difficult to start in code the program.Whateva it is i need to develop the program in order to be graduated.I am having a very hard time here as this title is given to me by my lecturer who is expecting me to do everything..Please anyone help to guide me.
My project is about using java to create a system which can monitor log file and uses some rules to correlate and output to end-user the prove of a particular problem (i.e: accessing pornography.).for more information find articles about event correlation system.
thousands of thanks in advance.Praveen_Forum wrote:

just forget it no one here would write code for you it is you who have to struggle and write some code come back if you have any specific questions regarding the coding or architecture or something like that so [Get Started|http://java.sun.com/docs/books/tutorial/getStarted/index.html]
OP didn't ask anyone to code it for him/her
that said, OP needs to put forth some effort
you'd think a final year student could demonstate a bit more understanding of how to interact in a community such as this
i'm also curious to know why a final year student has been given a software project but doesn't know how to program? -
Final Year Project - University
Hi all,
Just looking some advice and general tips, have a few questions about a final year project I am thinking of doing.
Basically it is going to be a stock control system for a nightclub, particulary focussing on their celler. The system will allow the staff/management to review stock levels and alerts will also be enabled to alert them to order appropiate stock, perhaps a draft invoice could be created automatically once stock hits a certain level.
This is basically to replace the old paper based method, could also include costing for each night.
To implement something like this, what am i looking at as in regards to software and how hard could be. What programs would guys recommend. I have done a little work on Oracle, but its pretty basic.
Thanks in advance.I'd say my suggestion is as good as anyones. Have you thought about using Oracle XE with its pre-installed APEX development environment? That should be more than enough to manage a nightclub's inventory.
Here's the link, just in case ...

Final Year Project! Please give me some idea!
I'm doing an individual final year project using IBM Aglet, JRun and J2ME. The topic is "Mobile agent shopping system", better with some theories. I have no idea about what types of application should be done. Initially, I intended to build a system for the customers to search for the products in a shopping mall with data mining recommendation(e.g. association-Apriori), but my supervisor want me to give him a new idea because previous students has built similar application (but using classification in data mining).
My supervisor has another 3 students doing the same project, but one of them doing a restaurant reservation system, another one has many multimedia in his system. The last one - I don't know. It seems that my project has no "selling points". I don't want to think of a quite complicated one as my programming skill is not so good. But the big problem is the project is restricted to a shopping mall. There is not much can be done. The project will be handed in 2 months later. I'm afraid that I can't hand it in on time. Does anyone have any suggestion on the topic. I have thought of this many times, but my supervisor still does not satisfy with it.
Please help me!http://mindprod.com/projects/projects.html

Oracle Final Year Project Choice Help Needed
hi everyone,
I m Amir from Pakistan, I m a student of CS final year at a IT University powered by Govt.of pakistan.
Can any one help us regarding choice of Final Year project/proposal. we want to build oracle based solution for any industry or sector which will also helpfull for me and my team not only for College Final Year Project but also for after college industry solutions.
As in consideration different sectors are in front of us, i.e Oil & Gas, Manufacturing, Automobiles, Communications etc
But, we think this forum is much help full cause different professional peoples are much better able to guide us with respect to current and upcoming trends.
Thanks
AmirHi Amir,
I can think of a dozen different projects. You could check the functionalities in Oracle's eBusiness Suite (Oracle Applications). For instance you could implement a human resource module (employees details, salaries etc), or a employee time card application. Why not a resource booking system (conference rooms, beamers, computers etc).
All these examples could easily be split into parts. Say for instance time reporting. One group could implement the interface to the employees, one group the interface to the managers, to the human resource department, and there's also quite some administrative setup modules.
What project proposals have you come up with yet?
Well, because it's your first post I warmly welcomes you to the Oracle Forums here at Oracle Technology Network.
Regards,
Martin Malmstrom

Help me in Doing my Final Year Project
Dear All,
I am studying BSc in Computer Science in American International University Bangladesh (AIUB), Bangladesh. I want to work with Java Card. Actually I want to complete my final year project in Java Smart Card.
I want to develop a Smart Card for student as mention in the link
http://java.sun.com/products/javacard/examples.html
1. when student insert the card in card accepantance device in entrance of the university all information(Name, ID,Photo, Department.....) will be displayed in the monitor of the entrance. After see the pic get keeper have no confusion about the student.
2. Student can also use this card to use the facilities of Library and Cafe.
Now dear all pls help me by proving this information.
1. What kind of hardware i need to complete the project and successfully deploy it to my university. Pls tell me briefly and if possible then tell me the link where i can but it.(If the parts are available in UK then let me know. It will be easy for me to collect parts from there).
2. What kind of Smart Card I have to use exactly.
3. If anyone ever develope this kind of project then pls email me at [email protected]
4. If possible then pls let me know the price of this hardware.
Its very vey urgent. I know all Java lover will definetly help me.
I am waiting for reply

Well then you have a number of points that can be solved very differently. Does exist any legacy hardware or software that need to be included into your project?
1. when student insert the card in card accepantance
device in entrance of the university all
information(Name, ID,Photo, Department.....) will be
displayed in the monitor of the entrance. After see
the pic get keeper have no confusion about the
student.Where do you want do store the student information? On card or in a centralised database? Who should be able to change information?
2. Student can also use this card to use the
facilities of Library and Cafe.Looks like money comes into play. "Stealing money" is always a good impulsion for any attacker. You should consider this in your system design.
1. What kind of hardware i need to complete the
project and successfully deploy it to my university.Sorry, but except for the hardware parts "chipcard terminal" (with or without pin-pad) and several smartcards I can give you only the answer: "That depends on what you want to achieve and how you want to do it"
2. What kind of Smart Card I have to use exactly.If you want to store the student image on the card, on of your main requirements would be a smartcard that has enough EEPROM for storing the image. Common JavaCards have 10 to 30kb for data and the applet code.

hi there
i am doing an applet for my final year project. at the end of this project i have to end up with a simple uml drawing applet. i have done some coding but am way outa my league and now i am stuck. i have managed to draw lines and rectangles but have no idea how to make the lines attch to the rectangles or how to move a rectangle around the screenonce it has been drawn. my email address is [email protected] if you mail me i can give you my program and maybe you can help meYou are right V.V, this applet is not finished yet, try this one,
press the oval/rectangle/desic buttons and add shapes by clicking on an empty square, after adding some shapes press the line button, by clicking on 2 shapes you will add a line to connect them. you can drag the shapes and the lines will follow.
Use double click for text. Drag the shape out of the screen and it will be deleted.

Final year project using labview, what project i can apply?
i'm goin to be do a final year project, n i thinkin to use labview do it.! but i dun hav idea tht is suit...coz it can't use to the station..
anyone can give me some idea??thanksGreetings!
Are you exposed to LabVIEW programming before or are you
planning on learning LabVIEW and graphical programming for your design
project. If you are looking for resources the following link is a great
way to start.
http://www.ni.com/academic/lv_training/how_learn_lv.htm
The three hour course is really easy. Once you are done my
recommendation is to use one of our shipping examples like temperature
control with DAQ assistant and PID. Please let me know if you have
issues setting up the LabVIEW development environment / programming and
post any questions.
Thanks much
