Displaying "Highest Price" indicator

Hi there,

I have a list of values that I am displaying in a table (Not using a loop)

I want to be able to put a graphic next to the item with the hightest price.

I have all of the prices in a table.

Any ideas?

Cheers

Well ... you now have to do a loop.
I want to be able to put a graphic next to the item with the hightest price.
Find the highest priced item *before* printing the items; when printing
only put the graphic if it is the right item.
I have all of the prices in a table.
A database table?
How do you get and print data from the database without loops? ?!?!?!
Any ideas?


Adapt this simple script that uses no database:

php$ cat max.php
<?php
$data = array(4, 7, 18, 3, 18, 6);

echo "Version a:\n";

$max = max($data);
foreach ($data as $value) {
echo ' a) ', $value;
if ($value == $max) echo ' GRAPHIC';
echo "\n";
}

echo "\nVersion b:\n";

$max_index = array_search($m ax, $data);
foreach ($data as $k=>$v) {
echo ' b) ', $v;
if ($k == $max_index) echo ' GRAPHIC';
echo "\n";
}

?>

php$ php max.php
Version a:
a) 4
a) 7
a) 18 GRAPHIC
a) 3
a) 18 GRAPHIC
a) 6

Version b:
b) 4
b) 7
b) 18 GRAPHIC
b) 3
b) 18
b) 6

sort a copy of the array from high to low, get the price in the first row,
check the next one to be sure there isnt more than one with the same price
(unless you are certain this cannot happen). That way you wont have to
search the whole array but will only last for one row, or however many
there are of the same high price. When you print out your list, use an if
statement to see if the current price equals the high price, if so then
print your graphic.

My problem is the last bit of coding below, the like statement does not work. what I have is a product options field and in it is stored characters i.e. "avcy" etc what the query does is that if I type in any single character all the products that match the criteria should be displayed. So if I typed in an "a" I should get 3 returns (see below) Fields could look like this: product.options: bhw djhsa

I think you would agree with me that a C compiler that directly produces Java Byte Code to be run on any JVM is something that is missing to software programmers so far. With such a tool one could stay with C and still be able to produce Java byte code for platform independent apps. Also, old programs (with some tweaking) could be re-compiled and ported to the JVM. We have been developing such a tool over the last 2 years and currently...

Howdy, In my GridView i have some bound columns displaying currency. I have DataFormatString="${0:C2}" in one of the columns but the value being displayed is $35 . If the price has cents, then it will display the cents, like $35.3 or $35.55, but where there's no cents, it just displays $35. Shouldn't this override any datatypes from the datasource.

Hi, I have a form with unbound fields on it. The user selects a record from a recordset and I populate the unbound fields. When I try to change the unbound quantity text box, Access 2003 tells me "The data has been changed. Another user edited this record and saved the changes before you attempted to save your changes. Re-edit the record." This does not always happen. And yes, I can re-edit the quantity text

Say price = 4179.00 or 4179 In VB6, when I do Format(price, "#.0"), it returns 4179.0, but in VB.NET when I do String.Format(price, "#.0"), it returns 4179.00. How can I do Format(price, "#.0") in VB.NET ? Thank you.
