Example:
#photoclip {
position:absolute;
height: 100px;
width: 50px;
clip: rect(0px, 100px, 40px, 0px);
overflow: hidden;
background: url(yourimagelocation);
}

Here, the rect() function accepts 4 variables. first two are the coords of the starting point of the cropping rectangle. The last two are cropping width, and cropping height.

"Overflow:hidden" means it will hide everything else outside of the cropping rectangle.

then in the html, you need to call the css style in div:

and also you can define the "width" and "height" of the dive .

Disadvantage:
When right clicking the pic and save , it is still the original picture. It is not actually cropping it, but hiding part of the picture.

In my opinion, the 99.999 % is kinda impossible. I do not believe anyone can fix a server problem in five minutes. So basically it is saying , this server is super stable with no down time.

1. Cheri wanted to add a function that she can view invoices from previous years. Thats fairly simple and I can just add one view offering this option.

2. In the form, they need 2 fields "Account" & "Activity Code" to be editable, because a few accounts or activities are not attached with particular indexes. I am thinking of adding a local table to store these special accounts and activity code. When loading invoices, it will check this local table first to see if thers any special ones, otherwise load the default.

3. Darin and Cheri also wanted a JV number input box. As above, it also can be included in that local table.

4. The Index search didn't work , I guess it was due to the code changing i made last night. But anyway, i need to fix it. And next time don't change any code before presenting.

5. Two fake indexes are needed to hold the bills of city halls or something else. So I'll make DPSST and OTHER in the indexes table. ( maybe a job to update the table every July 1)

6. 2 print reports and a yearly Report are needed too. Print reports are kinda easy . The yearly reports shouldn't be hard, depends on what records are needed.

So anyway, seems I need to spend one more week on this project

because oracle server has been moved, so the script folder doesn't have it's new IP. After the new IP is added in, the problem is fixed.

2. Got bunch of directory error saying my code kept looking for some file ''XXX.jpg'' in folder and couldn't find them.
The program runs fun, but I guess that annoys Mike Ross a lot. :(
Im gonna check the code today..If it gives hundreds errors , i think the job or the directory failed. but if there are only several errors , then it might be bad coding that didnt catch all error possibilities.
From the feed back from Mike, "the number of errors received varies quite a bit - sometimes a lot of errors all at once, then times when no errors of this type are received at all. Overall, it's a fairly steady stream of errors, but not tons of errors all the time." I think it should be lack of enough error catch.

So here are two problems I have with this design:
1. It has to look through "portal.users" talbe (generated from "directory" table). In the portal talble, the particular user has only one portal ID. And his name cannot be found on our WOU online directory.

I wonder if "not classified" staff member should be included in these tables too.

2. The function transfer V number to ldap always pull one of the ID back no matter how many status a user has. But if he is a staff, the print shop credit are supposed to go to the department index.

[^\w] not word chars \W
[^\s] not a space/blank \S
/i case not sensitive

/x - allow to add any numbers of "blanck"(space, enter or w/e)
/-?\d+\.?\d*/ #这是什么含义？
/ -? \d+ \.? \d* /x #要好些

^ matches the "beginning"， $ matches the end of the string. So， /^fred/ matches a string begins with 'fred' , it wont match 'manfred'.
/rock$/ won't match 'knute rockne'
(note: ^ in [] means "NOT", Otherwise , means string begins).

/^\s*$/ #It matches a blank line #它将匹配一个空行（blank line）

\b 词界锚定，是针对单词使用的。如/\bfred\b/可以匹配上单词fred，但不能匹配frederick,alfred, man fred mann

=~ 将告诉Perl 将右边的模式在左边的字符串上进行匹配
my $some_other = "I dream of betty rubble.";
if($some_other =~ /\brub/){
print "Aye, there's the rub.\n";
}

* Float Literials: 1.25, -1.0, 1.25e3
* Integer Literials: 3, -4, 2000

Strings

* Single Quoted String: 'hello', '', 'hello\n'
* Double Quoted String: "hello", "", "hello\n"
* back slash escape: \n is Newline, \r is Return, \t is Tab, \b is Backspace, \f is Formfeed, \a is Bell, etc ...
* Scalar Opertors: Numerical (+, -, *, /, %, ++, --, **, <, <=, ==, >=, >, !=) and String (. for concatenation, eq, ne, lt, gt, le, ge and x for repeating -- "fred"x3 is "fredfredfred")
* Other operators: !, ~, \, +, - (logical not, bit not, reference operator, unary plus, unary minus)
&, |, ^, &&, ||, ?:(bit and, bit or, bit xor, logical and, logical or, if-else)
, (comma) => (comma-arrow)
not, and, or, xor (logical not, and, or, xor)
* + can automatically convert number to string -- 3 + "a" is "3a"

Scalar variables
Begin with a dollar sign followed by a letter and then possibly more letters, or digits or underscores. Case sensitive.
The chop and chomp functions
chop($x): removes the last character of $x.
chomp ($x): remove the newline (input record separator).
Interpolation of Scalars into Strings
$a = "fred";
$b = " some text of $a";
Now $b is "some text of fred"
When scalar is in double quoted string, it is interpolated.
But not in single quoted string:
$a = 'fred'; $b = 'some text of $a';
Now $b is some text of $a', not changed.
The variable name will be the longest possible variable name that make sense at the part of the string:
$fred = "pay";
$fredday = "wrong";
$a = "It's $freday"; # not payday, but It's wrong"
$a = "It's ${fred}day"; # OK, it's payday
$a = "It's "$fred"."day"; $a = "It's".$fred."day";
undef: if you use a variable before it is assigned a value, like a zero in numbers or empty string in strings.
<STDIN> as a Scalar Variable
chomp ($a = <STDIN>);
Arrays and List Data
List Literal Representation
(1, 2, 3)
() -- empty list
(1 .. 5) -- same as (1, 2, 3, 4, 5)
(1.2 .. 6.1) -- same as (1, 2, 3, 4, 5, 6) if the number is not a whole number, just take the inside bound
@a = qw(b1, b2, b3); is same as @a = ("b1", "b2" "b3");
Array Variable
Start with @
The value of an assigned array variable is (), -- an empty list

dbms_lob.createtemporary(temp_blob,true,dbms_lob.call);
tempraw:= utl_raw.cast_to_raw(v_summary);
dbms_lob.writeappend(temp_blob,length(v_summary),tempraw);

update tablename
set summary2=temp_blob
where report_id=i.report_id;
commit;

and it gave me an error:

ORA-06502: PL/SQL: numeric or value error
ORA-06512: at "SYS.DBMS_LOB", line 826
ORA-06512: at "SECURITY.TEST", line 14
ORA-06512: at line 22

_--------------------------------------------------------_

ORA-6502 mostly occurs during execution of code in an oracle database due to a bug in the SQL or PL/SQL code. The primary reason this oracle error occurs is when you try to assign a value to a numeric variable but the value is larger than the variable can handle. ORA-06502 oracle error also occurs if you are trying to assign a non-numeric value to a numeric variable

1. Column & Bar : Columns with rounded corners looks the best.

   Histrogram is supposed to be used in some certain situation. but the one on this site doesn’t not look good.

2. Line & Area In this category I picked two: Auto-reloading chart is cool. But maybe refresh the page too much. and the one on Line & Area main page.

3. Pie & Donut: The 2D pie chart is good . The “Advanced navigation menus” look cool though, even it is not a chart.

5.Scatter & Bubble: Timeline is better.

<script language="javascript" type="text/javascript">
<!--
Function Check()
{
Return false;
}
-->
</script>

<form>

<form action="..." name="form1">
...
...
<input type="submit" value="1" onClick="return Check()">
<input type="submit" value="2" onClick="return Check()">
</form>

If the button type is "Submit", then it will submit the form first and then run the javascript. So, even the Check() function returns false, it will submit the form anyway.

Solution:
Change the type to "Button" instead.

<form action="..." name="form2" onsubmit="return Check()">
...
...
<input type="check" value="1">

</form>

create table tree (
id number(10) not null primary key,
name varchar2(100) not null,
super number(10) not null // 0 is root
);
-- from leaf to root
#select * from tree start with id = ? connect by id = prior super
# -- from root to leaf
# select * from tree start with id = ? connect by prior id = suepr
# -- the whole tree
# select * from tree start with super = 0 connect by prior id = suepr
--------------------------------------------------------------------------------------------------

Example:

create table test_connect_by (
parent number,
child number,
constraint uq_tcb unique (child)
);

insert into test_connect_by values ( 5, 2);
insert into test_connect_by values ( 5, 3);
insert into test_connect_by values (18,11);
insert into test_connect_by values (18, 7);
insert into test_connect_by values (17, 9);
insert into test_connect_by values (17, 8);
insert into test_connect_by values (26,13);
insert into test_connect_by values (26, 1);
insert into test_connect_by values (26,12);
insert into test_connect_by values (15,10);
insert into test_connect_by values (15, 5);
insert into test_connect_by values (38,15);
insert into test_connect_by values (38,17);
insert into test_connect_by values (null, 38);
insert into test_connect_by values (null, 26);
insert into test_connect_by values (null, 18);

-------------------------------------------------------------------------

select lpad(' ',2*(level-1)) || to_char(child) s
from test_connect_by
start with parent is null
connect by prior child = parent;
--------------------------------------------------------------------------------
Then it shows :
