smiley face in VB.NET

jcremeans11 — Sat, 07 Nov 2009 19:32:35 -0600

If you draw the smiley face in a picturebox instead of on the form itself, then you can hide the picturebox and make it come up when the user clicks the button.

Little Problem with INSERT INTO in Databases

cmwise — Sat, 07 Nov 2009 19:32:27 -0600

Hey,

Have you tried not inputting the primary key id? As in, using AUTO_INCREMENT or something?

I really can't see anything wrong with your SQL or anything else, but I'd try changing it to auto_increment just for troubleshooting... it's all I can think of doing.

Sorry if this isn't very helpful :-\

Implementing Comparable and using compareTo in Java

japanir — Sat, 07 Nov 2009 19:18:31 -0600

hi
posting your code would be helpful.
anyways, when implementing Comparable on your objects, just compare the name field by using the String's compareTo(String otherString) method.
as

CODE

//suppose object1 and object2 are instances of your new class.
if(object1.getName().compareTo(object2.getName()) == /*1 or 0 or -1*/){}

Whats the best language to build a website with & why? in Web Development

iphoneorange — Sat, 07 Nov 2009 19:15:42 -0600

There is no 'perfect' language. Each has its own specialties, so it's good to know several dialects /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" />

To make a website, you'll probably need:
HTML - The hypertext markup language is the standard way of presenting data in a web browser. All website use HTML
CSS - Cascading Style-Sheets, isn't much of a language, but more as a subset of HTML that can be used to style your websites.
Javascript - simple client-side scripting language. It's used to add effects to your page, but it has some limitations
PHP - a server-side programming language, it is can be used to work with databases, and work with files on the server (things Javascript can't do). PHP is very similar to the C programming language.

The languages you'll use depend mainly on the type of content. If you're making a simple game, you might use Javascript or Flash, but a MMORPG would need Java or ASP.NET

Linked list in C and C++

brac589 — Sat, 07 Nov 2009 19:14:24 -0600

Hi!!!
I think I am having trouble with my copy function......
--->The OLList::copy is a helper function for both copy constructor and the assignment operator. Its job is to generate a new chain of nodes with items identical to the items in the existing OLList object.
use new and manipulate pointer variables to create links.

--->Write a main program file to demonstrate successful copying of lists. Demonstrate:
copying of an empty list
copying of a list with only one item
copying of a list with many items.

we have to show that the copies are independent of each other (ie if 'a' and 'b' are OLList objects, and 'a' is a copy of 'b'. insertions to and removals from 'a' after the coying is done should not affect 'b'

--->The destroy function should remove dynamically allocated nodes of a linked list.

I think my destroy function is ok.

-->However, I cannot figure out how to stop the_list to not change after it its been copied to b.

Can someone help me out??

Also for the main.cpp( It is just a rough/test main....I wanted to check where I was going wrong)
I have done an empty list (ie OLList the_list)and a list with one item(ie OLList b and b=the_list)
--> first, does this sound right?

b's list equals the_list: [ 110, 220, 440 ]
b,s modified list:[ 110, 440, 550 ]
the_list is the same as before?[ 110, 440, 550 ]

the_list should still be[110,220,440] i believe

Convert HashMap to XML in Java

Yes it is possible. And since XML elements and attributes are user defined, I would use the following basic format:

CODE

<key>value</key>

There are some methods in the HashMap class you may find helpful. Check out the API:

Possitioning difficulties between a Div and an Img in HTML & CSS

Torroes_prime — Sat, 07 Nov 2009 19:08:39 -0600

okay, so I'm making this page that has a shadow around the right, left and bottom sides of the main contents of the page. I made a class for the body tag with the following setting:

CODE

    margin: 0px;
    padding: 0px;
    text-align: center;
    width: 100% auto;

Now, in order to get the shadow effect what I did was make a div with a background image on repeat-y, and inserted an image beneath the div. The Div has the following settings:

CODE

    height: 150px;
    width: 800px;
    background-image: url(../images/expirimentation_01_bg.png);

I'm thinking since the bottom image, and the div with the background image are the same width (both are 800px wide) and placing both the div and the image inside the body with the class I outlined before, they should line up nice and clean right?

Well you probably guessed that since I'm posting all this info here they're not lining up like I want them to. The Image in nice and center, but the div is right up against the left edge of the window.

Um... what did I do wrong with this set up?

Zend Certification Pointers in Corner Cubicle

See if you can find a PHP 5 Zend test dump around the internet.

I honestly don't think highly about certifications, though. If you are confident about your stuff, I wouldn't waste my money on a certification, but instead try to contribute with open source projects to get some experience.

Write code that will demonstrate your capabilities.

When you do find a test dump, just keep trying to answer them until you get a 100 percent.

My teacher mentions that all the time because he works for Zend...supposedly it is the PHP industry standard. Have you checked Zend's website to see what materials they have available? You might want to post this on the PHP board.

If they cut your hours from full time to part time, you could tell them you'd rather be laid off, because that is a huge change in hours. You should verify with your unemployment office before telling them that, but if yours is like mine (Chicago), being cut from 40 to 20 hours is an acceptable reason to leave a company. Then you'd get unemployment and could look for a job at a company you want to work for that could offer you f/t hours.

Java Prices in Java

japanir — Sat, 07 Nov 2009 18:58:14 -0600

first the array data type should be double instead of Double.
Double is a class, while double is a primitive data type.
check for the differences if it is new to you.
second, why do you use while loops? this is a classic task for a for loop. you know the number of iterations you should do.
seperate each task into different methods.
then call each method in the way you choose.
ill give an example for the first 2 tasks.

CODE

public class Class1
{
    public static void main(String[] args)
    {
        double[] prices = { 2.34,  7.89, 1.34, 10.29, 21.23, 13.50, 80.69, 56.79, 23.19, 10.99,

                       70.89, 41.26, 8.92,  3.56,  7.66,  9.55,  3.77, 24.90, 82.71,  2.81};
        System.out.println("The sum is: "+ getSum(prices));
        displayLessThanFive(prices);

    }
public static double getSum(double[] array){
        double sum = 0;
        for(int i=0;i<array.length;i++){
            sum+=array[i];
        }
        return sum;
    }
    public static void displayLessThanFive(double[] array){
        System.out.println("Values lower than 5.00:");
        for(int i = 0;i<array.length;i++){
            if(array[i] < 5){

Hi to all,

I'm currently facing a dilemma in my career. Hopfully you guys could give me some wise suggestion or insight

I'm currently working as a programmer and IT support in muti-national Company ,IT department.

I working on a project and occasionally need to assist my senior to do IT support. After working there for 2 years, I can't find or can't feel myself any dramaiclly increase in my experince on programming. It's like if i was to work alone, I still would not able to fend for myself at all. Still feeling newbie on programming. And in IT support which is not my core job, it's like doing basic helpdesk support, mostly doing the repeated case. Currently, I don't find my manager is trying to groom me any where. For your information, he just promote one year plus as a manager, so i think there is any available position for another manager.

I got a feeling, that beside the project I'm working on, the next reason that I'm needed is in that department is because I am the most jr and the only guy in the department, the rest is ladies. Whenever there are any heavy equipment that need to ship or carry off to another department, I will have to do it. These happen so often that it naturally become my job too.

Is there any prospect in my career with this company?

If not, Should I hop to another company, hopfully an IT company?
But the next problem is I'm current persuing a programming degree, will it give me problem?

Please guide me with your suggestion?

I'm in almost the exact same boat. I have a decent job, but not a lot of room for growth and I'm only picking up random skills and not becoming an expert at anything. Also, I'm in school for programming. I would say that if there is no chance of you getting laid off, start sending out your resume for a few jobs you'd really want. Otherwise, stick with it a little longer until you feel more secure in the programming, and then send them out. I'm the same way though, looking forward to programming, but all of my skills now are network admin skills. If I get into IIT for graduate school/software engineering, I'll be quitting this job in Aug to do that full time.
