Question by dsfan182: Help with ap computer science extra credit project.?
Here is the description:

For this project, you will write a program that processes an HTML string. Your program
will contain a declaration for a character array called html that will be initialized within the main
function. For example:
char html[500]=”

Welcome to my page

Here are my links…
“;
• Your main function will traverse the string, checking for html tags.
• When a tag is found, it is stored in a variable and sent to tag_cntrl as a parameter. A tag
is defined as any substring that is enclosed in angle brackets for example, in the string
“” , “body” is a tag. Your program will ignore all tags except “body”,”p”, “hr”,
“br”, and “/html”.
• The program should stop traversing the string either when a null character is encountered
or when the tag “/html” is found, whichever comes first.
• Everything that is in the string after the first “” and before the first “”
except for characters enclosed in angle brackets should be printed to the screen.
• An error message should be printed if there is a ‘<' found in the string and there is no '>‘
found between the opening bracket and the end of the string. For example:
“

Error, no closing bracket for opening bracket at position 14.
• An error message should be printed if your program reached the end of the string (the
null character) and a "\html" tag has not been found.
• Your program should be able to handle upper case tags as well as lower case. For
example, . You will need to change your tag_cntrl function to do this. You do
not need to worry about tags that have mixed upper and lower case, like .
• You will be required to create a header file for your function prototypes. (You don’t need
to worry about this while you are writing the algorithm)
• The only function you are allowed to use from the string library is strcmp.
• You could earn bonus points by adding more functionality. However, please talk to the
instructor beforehand.
IMPORTANT: Make sure there are no extra spaces or newlines in your definition of html

The usual way we start projects in class is:

#include
using namespace std;

or something very similar.

Thank you soooo much!

Question by : Javascript OnFocus Help?
I am trying to make a function called ‘setage’ that when you click on the ‘Age’ TextField, it automatically computes the age from the date of birth and displays it in the textbox. I also the age to go down one if the birthdate is past June 1. For some reason, it cannot display it.

function setage (form)
{
var dob = form.birthdate.value;

var mo = dob.substr(0,2);
var day = dob.substr(3,2);
var yr = dob.substr(6,4);

var this_age = 2011 – yr;
if (mm >= 6)
{
this_age–;
}
form.age.value = this_age;
form.submit();
return;
}

Best answer:

Answer by Ratchetr
If you run in FireFox, click in the age box, then look in the error console (tools menu), you’ll see:
Error: mm is not defined

You declared variable mo, but you are using mm in the if statement.

Q&A: Any help with DIV tag web page layouts?

admin — Mon, 23 Apr 2012 03:00:05 +0000

Question by riggers: Any help with DIV tag web page layouts?
Hello everyone.

I wondered if you’ll could help me out?
I’ve created a web page using DIV tags, and styled most of it using CSS. All has gone well and I’m now ready to begin work on the second page.

On my first page, I’ve structured the DIVS with selectors like so,

#header

id=”header”

#subheader

id=”subheader”

#horizontallinkbar

id=”horizontallinbar”

#mainbody

id=”mainbody”

#sidebar

id=”sidebar”

#footer

id=”footer”

These are all structured independently of each other.

On the second page, I’ll keep all the elements the same, except the #main body, which i need the height to be bigger. (I assume I have apply a different ID for this?)

So i opened up my new page, layed out a new set of DIVS, attached a set of ID’s (the same id’s as mentioned, except the main body) and finally, attached my style sheet……

……Bingo! all of the DIVS suddenly took on the form of the first page, colours, and sizes. Excellent I thought. The only problem is, when I create a new DIV for the second page #main body, with a different ID and preview it in FF, it floats to the left hand side, even though I set the margin to “auto” I can’t figure this out!

I’m assuming that in each new page, where I want multiple elements to be exactly the same as the previous pages, I just apply an identical ID to each of them, and then by attaching style sheet to that page, the elements will be the same? And like wise, if I want one particular element to be different, or unique, I just give it a unique ID?

But why would this effect the positiong?

Would you’ll have a look – http://www.riggerz.org/gvs_mock_up.html
This address is the main page, and if you click on the link at the top of the page, which in white, reads: “history” from there, you’ll see my problem. (viewed in FF) But, renders ok in IE8 (compatability view)

I don’t get it? The index page looks fine in ALL browsers though!

I really appreciate any help, and patience for reading all this!

Answer by Motley
You wouldn’t put your ID in the middle of your div tags, you put them in as a propertry of the tag itself.

Yours:

id=”header”

Need help altering image dimensions that I’m inserting into my website?

admin — Mon, 20 Feb 2012 10:44:35 +0000

Question by : Need help altering image dimensions that I’m inserting into my website?
Ok, let’s see if I can ask this correctly…
I have a website thru JustHost and am using “their” templates. I’m scanning flyers (w/color, design and text) that need to be “readable”. But no matter how much I alter the size, pixels, etc, the images are shown in the same exact size once they’re on the website.
Now… when working in my website’s “admin” mode, while on the php page (where I’m uploading these images as hyperlinks), I have an option to view the html code, and where the text of the hyperlinked image is, it says the following:

Image
As you can see, I see nothing relevant to the image “size”… Can I “add” something to change the image size? Such as a percentage or dimensions, for instance? Without messing up the template’s “design”?
And I’m saying “design” because I don’t know the proper term for what I’m trying to say, since when I’ve made other alterations in the past to the template’s commands (not sure if that’s the right word either), I notice the template’s design gets distorted… and if I “undo” such alteration, it doesn’t necessarily go back to the way it was once I’ve saved changes :/

I don’t see a class or ID that refers to an image, nor the -tag, only an anchor (which is a link), a division box, etc. In your case, try to post your image in the HTML as:

Can I get help from someone who knows HTML?

admin — Sat, 04 Feb 2012 04:43:33 +0000

Question by Living life – one day at a time!: Can I get help from someone who knows HTML?
I’m building my blog through blogger, and I found a template I really like. Except I don’t want it to say the date of the post, and I don’t know how to fix it. Since its all html, and there’s not DIY tutorials out there for me to use.

Can someone help me out? What do I need to delete to make it now show the date a post was posted?

These are the only parts I found that even say date:

type="color" default="#000000" value="#000000">

type="font"
default="normal bold 117% Arial, sans-serif" value="normal normal 97% Trebuchet, Trebuchet MS, Arial, sans-serif"

h2.date-header {
margin: 10px 0px 3px 0px;
padding: 0px 0px 0px 0px;
text-align: left;
color: $ dateHeaderColor;
font: $ dateHeaderFont;
text-decoration: none;
text-transform: uppercase;
}

.date-header span {
margin: 0px 0px 0px 0px;
padding: 0px 0px 0px 0px;
}

Thanks to anyone who can tell me what I should be looking for!
I don't really know how to read html, anything I've done has been following EXACT steps from tutorials. So I'm pretty stuck at this point.
Thank you! Thats exactly what I wanted!!

Best answer:

Answer by David D
try placing

***display:none;*** (without the stars)

in between the h2.date-header{} and .date-header span{} tags

ex:

h2.date-header {
margin: 10px 0px 3px 0px;
padding: 0px 0px 0px 0px;
text-align: left;
color: $ dateHeaderColor;
font: $ dateHeaderFont;
text-decoration: none;
text-transform: uppercase;
display:none;
}

.date-header span {
margin: 0px 0px 0px 0px;
padding: 0px 0px 0px 0px;
display:none;
}

What does it mean by “space” when crocheting? Help with this line!!?

Question by txrose: What does it mean by “space” when crocheting? Help with this line!!?
I am a beginner at crochet and working on these cute fingerless gloves (trying to do something new…tired of blankets lol) I have never done anything that involves “spaces”. I have no clue what it means or how to do this, and the vids or instructions I have found are not helping. The show large stitches and this is very small, so it is not as obvious. Here is the part I am struggling with:

Ch 1, *sc in next ch-1 sp, ch 1; repeat from * around; join with slip st in first sc.

Q&A: PHP Code (Help is greatly appreciated)?

admin — Sat, 10 Dec 2011 16:00:03 +0000

Question by David O: PHP Code (Help is greatly appreciated)?
this is an example: http://gaia.ecs.csus.edu/~mei/122/examples/time_table.php

I am generating a multiplication table that runs numbers 2-15 depending on which number the user chooses to input.

The problem is when i input a number it infinetly multiplies the number by 1.

Here is the code:

// time_table.php - a demo of using functions and include file script
// Get the functions we need for this time table
// Using extension "php" instead of "inc" will prevent others see the code

include_once("tt_functions.php");

# MAIN-PROGRAM
$ title = "The Times-Tables";
html_begin ($ title, $ title);

#Validation of input and then produce the Times-Tables
#
if ($ submit)
{
if ($ n == ''){
?>
Oops, your forgot to supply info required.
Please correct the problem and try again.

}
else if ((!ereg("[0-9]", $ n))){
?>

Please restrict your input to only numbers.

}
else if (($ n >= 15 ) || ($ n < 2)) {
echo "Number Range Error.";
}
else{

//ready to produce the time tables
//function timetable( ) was defined in the included file function_timetable.php

timetable($ n);
}
}

// Forms to collect user input
?>

Here is the tt_functions:

# A collection of functions to make our time table engineering
# easy to understand. It will be included in time_table.php

function html_begin ($ title, $ header)
{
print ("\n”);
print (“\n”);
if ($ title)
print (“$ title\n”);
print (“\n”);
print (“\n”);
if ($ header)
print (“

$ header

\n”);
}

# put out final HTML tags for page.

function html_end ()
{
print (“\n”);
}

function timetable ($ n) {
// Go through each table
for ($ table=1; $ table<=$ n; $ table++)
{
print "

The “.$ table .”Times Table\n”;
//Produce $ n lines for each table
for($ counter=1; $ counter=$ n; $ counter++)
{
$ answer = $ table * $ counter;

//Is this an even-number counter?
if ($ counter % 2 == 0)
//Yes, so print this line in bold
print “
$ counter x $ table = “.
“$ answer“;

else
//No, so print this in normal face
print “
$ counter x $ table = $ answer”;
}
}
}?>

Again help is much appreciated. Thank you for taking the time to read this.
