Code Help Please.

I am havong trouble getting equations to work on my calculator.
I have the basic going, but as soon as I try to add any more to it at this point it will not compute.
I need to add commission to the 20% and 5% based on the T1 and T2 x $25.00.
Can a figure only be used once in any equations?
I need to use the input for T1 to generate different #'s in 2 other fields.
Here is a link to it,

Could someone please help?

PHP/mySQL code help please

Hi all,
Thanks to David Powers fab tutorial I am now well on my way to competeing my first dynamique website using PHP/mySQL, (thanks David ), however I am stuck on one particular area....can anyone please help?
I know that the mySQL database uses the format YYYY/MM/DD for dates, and that is fine. I've sorted out how to display in a more regular format (eg. 1st September 2011) for my application, but I am stuck on how to convert a more regular formatted date entered by the site user into the mySQL format.
Ideally I would like for the users entry or say either 1/9/11 or 1-9-11 (or something along those lines, to be recognised and displayed on the entry form, but to have a backend function that converts the data to mySQL format. I seem to be reading plenty of forum posts which say this can be done, but unfortunately I can't quite seem to fathom how, or where the code should sit. Would someone mind taking a look at my code page to actually identify what I need to insert, and equally as importantly...where!!!
Along these lines...is it possible to have a mini-calendar date picker that could be embedded next to the date entry field to ensure that a valid date is entered and in the correct format? Where could this be sourced?
Thanks in advance of some much needed help
Mark

This is becoming really frustrating for me (so god knows how I am to you!!!!), but I usually pick things up so fast and yet this whole PHP/SQL thing is eluding me!!
I can see (I think) how the code would work, but am struggling to see where it fits into place with my own Dreamweaver 'Update Record' code, as follows. I have spent a couple of days trawling through PHP.net and various other sites and forums before bringing my stupidity to the public domain, but I just can't seem to crack it.
This one last time then i'll leave you in peace??????

Iframe shows only code - Help, please!

I'm on OS X 10.4.5 and have designed a website that uses iframes (this is a must as there is a lot of content and I do not want the page bigger than the set size, so I need a way to scroll the content within the page size (955x600). I use Firefox for myself (and it looks great) but the person I'm doing the site for uses Safari. When he sees it, needless to say, it isn't going to look right. All it's displaying is the code for the iframe page as if I'm viewing the source for the page (within the iframe on the main page). Have they fixed the problem with iframes in Safari? And if so, what do I need to make it work in both browsers? Or is there another design tactic I can use instead of iframes?
Any help or suggestions are very appreciated.
Thanks!
Mac mini Mac OS X (10.4.5)

I actually found my error. It wasn't code within the file but I had saved it as a .php file (based on a file I found at another website that used it for their iframe) and when I changed it to .html it worked! But thanks, again, for your advice because it caused me to research iframes and I found they were all using .html/.htm files to call on.

Bar Codes(Help Please)

Hi,
I want my application to read bar codes of items and to store them to my database.Please, can you tell me if it is possible with Forms6 or Forms6; if so, please explain me the procedure even I want to insert records or I want to make updates(for example the quantity of an item with its bar code).
Thank you to answer me.Regards.

You mean store the image of the bar code ? Why do you want to do that ? A bar code is just the graphical representation of a number. Use a bar code scanner to translate the bar code to a number and store that. It will be much better. At least then you will be able to search for your product by that number and update the record with the qty as and when you wish.

Trouble with some code help please

i need help with this program i have to do a webclient in java i will put here the instructions that were given to me and then the work i have been doing so you can have an idea of what i'm doing any help you give me i will be very thankful thanks.
Here are the instructions
The class WebClient will represent a simple web client. This class must provide the following functions:
1. connect to a web page using a URL
2. obtain or get the response from a server
This funcionality will be provided by the public interface of the class:
- WebClient( )
Creates a new object of the class
- void setURL(String url)
Used to indicate the URL of the web page
- String getResponse()
Gets the response of the server to the page who's URL was indicated(Example of a response: HTTP/1.0 200 OK)
You have to implement the following:
1. The class WebClient with an public interface that Includes the methods specified upwards, in a file called WebClient.java
2.A class WebClientTester, in a file called WebClientTester.java, with a main program that minimun have to:
a) Create a instance of WebClient
b) Using 3 valid URL's
- Invoque setURL to indicate the URL of the server
- Invoque getResponse to get the response of the server
- display in the console the response of the server
c) Using 3 invalid URL's (this is the correct server but the page does not are on the server)
- Invoque setURL to indicate the URL of the server
- Invoque getResponse to get the response of the server
- display in the console the response of the server
As a tip they give me that i can use the clases HttpURLConnection and URL to implement WebClient. It is recommended to save the URL in an instance field of WebClient.
Those are the instructions now i will write here what i have do until now
This is the WebClient Class:
public class WebClient
     public String Wecli;
     public WebClient()
          Wecli = new String();
     public void setURL(String url)
     /** need code here */
     public String getResponse()
     /** need code here */
     public void display()
          System.out.println(Wecli);
what i need there is the methods constructors or whatever are so that setURL and getResponse work and do what are suposed to do.
Here is The WebClientTester class
public class WebClientTester
     public static void main(String[] args)
          WebClient wbcl = new WebClient();
          wbcl.setURL(http://www.nba.com);
          wbcl.getResponse();
          wbcl.display();
          wbcl.setURL(http://www.mlb.com);
          wbcl.getResponse();
          wbcl.display();
          wbcl.setURL(http://www.msn.com);
          wbcl.getResponse();
          wbcl.display();
     wbcl.setURL(http://www.nba.com/baseball.html);
          wbcl.getResponse();
          wbcl.display();
     wbcl.setURL(http://www.mlb.com/basketball.html);
          wbcl.getResponse();
          wbcl.display();
     wbcl.setURL(http://www.msn.com/practice.html);
          wbcl.getResponse();
          wbcl.display();
that is basically what i think i need so that the program works any other help you can give me will be very useful thanks for reding it and give your opinions.

Those are the instructions now i will write here what i have do until nowLooks like you've posted your homework instructions, done less than the bare minimum to make it look like you thought about this problem, and now you want strangers to help you cheat by giving you the code that does the work so you can hand it in as your own.

I am making a program where there are 3 ellipses. For two of the ellipses I want they to be able to be dragged across the screen when the mouse is pressed on them, they will also change color. For the third ellipse I want all three ellipses to move and change color when I click on it. I have the two ellipses doing what I want but I cant get a third move them all. Thanks.

Cryptography: strange msdn sample code, help please....

Apparently that line of code does nothing, to continue the discussion
I would like to know your guys opinion of MS and the level of security they provide, I assumed everything was top-notch, but looking through their usage of their own libraries it appears they are incompetent.
Can I get some opinions on this, I have updated the question to a discussion
ORIGINAL QUESTION - EVERYTHING BELOW (irrelevant):
I have been able to create a complete class for network server and client TCP/IP unlimited secure data transmission using RSA/AES (.NET framework cryptography only), and am implementing an EC/DH version (.NET framework cryptography only). Everything
is working ok, I was just curious: on the VB example on this page:
https://msdn.microsoft.com/en-us/library/system.security.cryptography.ecdiffiehellmancng.aspx
What is the purpose of this line:
Dim k As CngKey = CngKey.Import(bob.bobPublicKey, CngKeyBlobFormat.EccPublicBlob)
On this page in the VB example??
EDIT reason: forum bug correction
EDIT2: I have noticed that the people writing the msdn samples do not understand the underlying cryptography, mostly based on their naming of variables. For the most part their usage follows the federal standards. Should I be worried that MS might not be
properly implementing the .NET cryptography algorithms?

You have completed the class and everything seems fine, you sent several GB of data through the class and it appears to be as secure as the RSA version. However, you found a line in a sample that isn't needed so you are concerned that they may be incompetent
and the .NET crypto libraries may not be secure. Is that an accurate description ?
I listed a single example, I have found dozens of them - including many examples which break the security rules and no information is given that it is doing such.
Did you have any opinion or you just want to stir up arguments???
I think the code is fine. I programmed a windows phone application myself and the samples are okay but most of the Microsoft samples are starter points and in some they clearly state that and not to use the code in production machines (if you have not noticed
that in the MSDN programmer documentation you probably are new to Microsoft programming or have only been programming a few years on their platforms). This excludes the GUI controls included with some of the samples for windows application which
are expected to work. They are one of the few and only rare exceptions to this rule. vb.NET 0.0 is right Microsoft is slow sometimes to stay modern but the libraries are effective.

}I think only those classes affect the problem. Thanks.

They all complie separately, but when I complie PlanetApp which creates the frame it has the problem. It says it can't find the symbol for ball for all the methods that I call with it, such as ball.setEccentricity(...) or _ball.fill(...). Here is the PlanetApp class. Thanks.
public class PlanetApp extends javax.swing.JFrame
    ControlPanel _controlPanel;
    MovingBallPanel _movingBallPanel;
    public PlanetApp (String title)
     super(title);
     this.setSize(600,500);
     this.setBackground(java.awt.Color.BLACK);
     this.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
     _movingBallPanel = new MovingBallPanel();
     _controlPanel = new ControlPanel(_movingBallPanel);
     this.add(_movingBallPanel, java.awt.BorderLayout.CENTER);
     this.add(_controlPanel, java.awt.BorderLayout.SOUTH);
     this.setVisible(true);
    public static void main (String [] args)
     PlanetApp app = new PlanetApp("Lab 7");

Need a little beginner code help, please

How do I modify the following code so that a different button
(like btnAbout) can use the same function?
btnHome.addEventListener(MouseEvent.ROLL_OVER, over);
btnHome.addEventListener(MouseEvent.ROLL_OUT, out);
function over(event:MouseEvent)):void {
btnHome.gotoAndPlay(2);
function out(event:MouseEvent):void {
btnHome.gotoAndPlay(7);
}

use the attach code option to display code in this forum:

My bluetooth keyboard (Macnus 3.0) is recognised by my iMac but will not pair? I have paired it with my iPad using code 8310 but it still will not pair with my iMac. Can someone help please?

My bluetooth keyboard (Macnus brand - bought recently in Thailand)(similar to Mac small keyboard) will pair with my iPad using code 8310,and is recognized by my iMac but will not pair?
There are very scant instructions with the keyboard and no mention of any code (the code was prompted by my iPad).
I have followed the instructions but it still will not pair with my iMac!
Can anyone help please?
My iMac is 20 inch Mid 2007 OSX10.9.1 4GB RAM

Hi All, thank you for you suggestions. I have been unable to find any website for the maker, but have looked at several Thai/cambodian sites incl <http://www.buycoms.com/Article/8435/index.asp> which mentions the keyboard being suitable for tablet or windows. No mention of iMac! although the box is branded to indicate Mac compatable.
I'm thinking that maybe it just will not pair with an iMac.
Ill keep looking for the maker website, which might come on later in the future? maybe?
thanks again.

Edit: thanks for cross-posting this question on another forum. I now see that I wasted my time trying to study your code in the java-forums to help you with an answer that had already been answered elsewhere (here). Do you realize that we are volunteers, that our time is as valuable as yours? Apparently not. Cross-post again and many here will not help you again. I know that I won't.

Code Help Please.
