The programming/developement help wanted/needed thread

[samh16]

Lots of IT college students on here, aswell as people workng in the industry, so this thread is the place to post if you need help, whether it be programming, web dev, assignments or personal projects.

Be specific in your question, give as much detail as possible, and give snippets of code when needed!

And maybe everyone could say what they're experienced in, so we could get a list of people to go to with specific problems?

EDIT: I'll update the OP with various links and tutorials for all sorts of dev'ing.

http://www.dreamincode.net/ --- Lots of languages, really good place to have a look around.

http://codingbat.com/ --- Programming questions you can answer in Python or Java.

http://projecteuler.net/ --- Lots of math problems, you can use any language you want to solve them.

http://developer.android.com/index.html --- Anybody wanting to make android apps, start here. (You should have a good grasp of Java before you start)

http://developer.apple.com/iphone/index.action --- Same as above, except for iOS. (Pretty sure they use Objective C, but I could be wrong)

http://sourceforge.net/ --- Lots of free, open source software, aswell as dozens of projects you can get involved in. Any Language.

I still have all my old programming 101 projects if anyone needs something...although it would be best just to help that way people learn...lol. Mostly Java stuff, but some VB also.

[Alephz]

Definitely going to keep my eye on this thread. I'm not fantastic but I know a bit with java and prolog.

[Boatski]

i know cobol, it's ok

[deadforaminute]

cool

[Veldy]

Dabbled in Matlab last year for a class..

So if anyone is taking an intro level Matlab course and needs some help..


I also know some people who know a lot more about it than I do, so I can ask them if need be

[circusmidget]

I'm studying IT at the moment. I'm not an expert by any stretch of the imagination, but I have tinkered in the following languages (some more than others):

C, C++, Java, C#, Perl (dear gods, how I loathe), Python, M68k asm, x86 asm. I think that's it.

I've also tinkered with XHTML, CSS, XML (+DTD/W3C Schemas), PHP and SQL (my).

[neilsabo]

i suggest we compile a list of links for tutorials in various tools/languages in the OP

if i knew any, i'd start, lol...

[brahdawg]

Remember kids, its not so much the language you know but the programming concepts that are important.

For learning basic web stuff the w3schools has a bunch of useful little tutorials.

[EasTexan]

This thread should blow up once the fall semester starts. I know I'll post here for sure. I'm taking an "Internet Technologies" class over the summer for my IT minor, basically how to make webpages, should be an easy A.

Majoring in computer science and minoring in IT.

Wassup guys. I'm a noob here so forgive me.

I'm trying to do a simple html web form for practice (contact information).

Some of the fields, however, require validation using javascript.

So is it possible to do all my forms under one form tag and use one script to validate the fields that need validation, or should I just paste in all the forms together and post separate validations for each one?

[Considine]

HTML, CSS, PHP and still tinkering with Flash (inb4 "HTML 5 FGT").


jQuery is so awesome. Gives me boners guise.

I don't do any coding at the moment but you should like C#, very similar syntax to Java

I'm currently going through some ASP.NET 3.5 textbooks. Have done a bit of VB.net and am now learning C#.

Is it multiple forms , or one form with multiple fields?

I'm guessing it's the latter, in which case you could use a for loop to run through the form while checking each piece of info.

Have a look here : http://www.elated.com/articles/form-...th-javascript/

And here is some code from that page that handles multiple fields at once :http://www.elated.com/res/File/artic...rm_source.html

Any time, that's what the thread's for.

And btw, is it cool if I PM you with sites to add to the OP every now and then? I can't edit after 24 hours...

Cool.

Back on topic: Anybody in the middle of any projects/assignments atm?

[Coal Man]

Yep me, pretty soon I'll have to do up some web pages for an assignment.

Ok javascript is almost done. I've been tinkering around with it and the last part is pissing me off. I put in validations for the fields but the javascript to validate the zip code is very tricky.

I got the code from this site http://javascript.internet.com/forms/val-zip-code.html
but when I put it in, it doesn't work and disables the rest of the script from working


This is what I have so far, just need the zip code help:

<head>

<script type="text/javascript">

<!--

function validate_form ( )
{
valid = true;

if ( document.contact_form.title.selectedIndex == 0 )
{
alert ( "Please select your Title." );
valid = false;
}

if ( document.contact_form.firstname.value == "" )
{
alert ( "Please fill in the 'Your Name' box." );
valid = false;
}

if ( document.contact_form.lastname.value == "" )
{
alert ( "Please fill in the 'Last Name' box." );
valid = false;
}

if ( document.contact_form.usrname.value == "" )
{
alert ( "Please fill in the 'Username' box." );
valid = false;
}

if ( document.contact_form.pwd.value == "" )
{
alert ( "Please fill in the 'Password' box." );
valid = false;
}

if ( ( document.contact_form.membertype[0].checked == false ) && ( document.contact_form.membertype[1].checked == false ) )
{
alert ( "Please choose your Member Type: Normal or Premium" );
valid = false;
}

if ( document.contact_form.address.value == "" )
{
alert ( "Please fill in the 'Address' box." );
valid = false;
}

if ( document.contact_form.city.value == "" )
{
alert ( "Please fill in the 'City' box." );
valid = false;
}

if ( document.contact_form.terms.checked == false )
{
alert ( "Please check the Terms & Conditions box." );
valid = false;
}



return valid;
}

//-->

</script>

</head>

<body>
<form name="contact_form" action="html_form_submit.asp" method="get" onSubmit="return validate_form ( );">
<form action=""><h3>Title:</h3>
<select name="title">
<option>Mr.</option>
<option>Mrs.</option>
<option>Miss</option>
<option>Other</option>
</select>
<br />
<br />

<h3>First Name(Required):</h3>
<input type="text" name="firstname" size="20" />
<br />
<h3>Last Name(Required):</h3>
<input type="text" name="lastname" size="40" />
<br />
<br />




<h3>Username(Required):</h3> <input type="text" name="usrname" />
<br />
<br />




<h3>Password(Required):</h3> <input type="text" name="pwd" />
<br />
<br />



<h3>Member Type(Required):</h3>
<input type="radio" name="membertype" value="Normal" /> Normal Membership<br />
<input type="radio" name="membertype" value="Premium" /> Premium Membership<br />
<br />
<br />



<h3>Contact Type:</h3>
<input type="radio" name="contacttype" value="Home" /> Home<br />
<input type="radio" name="contacttype" value="Work" /> Work<br />
<br />
<br />



<h3>Best time to contact me:</h3> <input type="text" name="contacttime" />
<br />
<br />




<h3>Address(Required):</h3>
<input type="text" name="address" size=100 />
<br />
<br />


<h3>City(Required):</h3>
<input type="text" name="city" size=50 />
<br />
<br />


<h3>Country:</h3>
<input type= "text" name="country" size=50 />
<br />
<br />


<h3>Phone Number:</h3>
<input type= "text" name="phone" size=20 />
<br />
<br />

<h3>Email:</h3>
<input type="text" name="email" size=50 />
<br />

<input type="submit" value="Submit this form"
onclick="formvalidation(contact_form);return false;" />
</form>
</body>

Otherwise this is my first form and it's pretty fun

[samh16]

@CoalMan, the last part should be

<input type="submit" value="Submit this form"
onclick="validate_form(contact_form);return false;" />

because 'validate_form' is the name of the validation script you have, when the button is pressed it calls the script and excecutes it.

Any javascript ninja's have any idea about the zip code part?

[Boatski]

Coal, can you post what you're using with the Zip stuff on it? I don't see anything from what you posted above.

Try this maybe.

Thanks will edit the submit button now.

I left the zip code text field and the javascript out.

The funny thing is when I copy the code they say to copy here:

http://javascript.internet.com/forms/val-zip-code.html

and paste it in a text file by itself, it works.

I just don't know how to incorporate it into my text file with everything else.

[Coal Man]

@CoalMan, the last part should be

<input type="submit" value="Submit this form"
onclick="validate_form(contact_form);return false;" />

Ok here's the difference when I try this.

The way I had it before, the alert for each empty field popped up once which is what it's supposed to do.

When I changed formvalidate to validate_form, the the same thing happened, but it looped again and all alerts came up twice.

That's why. Is that return statement needed? Either remove that one or the one at the bottom.

Ok I get you.

So how about if I put "onSubmit="return validateZIP(this.zip.value)" in the initial statement and leave validate_form in the submit button. Will that fix the zip code problem?

http://developer.apple.com/iphone/index.action --- Same as above, except for iOS. (Pretty sure they use Objective C, but I could be wrong)

Objective-C is correct.

Some good books for Mac/iPhone development would be:

Programming in Object-C 2.0 by Stephen Kochan
Cocoa Programming for Mac OS X by Aaron Hillegass
Core Animation for Mac OS X and the iPhone by Bill Dudney

Aaron Hillegass has a new one out, but cannot think of the title.

in and subbed. I plan on learning at least one new language this summer, probably C++ or something. My schools program isn't the best, so I'm learning as much as possible.

my submission to this 'pool of knowledge'
(Coal Mayne if this goes against the rules plz just delete post thx)

C++ is definitely a good one to learn and be proficient in.

another book for Mac/iPhone is:
Beginning iPhone 3 Development Exploring the iPhone SDK by Dave Mark and Jeff LaMarche


edit:
once you understand object-oriented programming, picking up other OO languages should be fairly easy.

IE C++ to Objective-C. They're very similar.
