A better approach would be to take a char rather than a String in that method, since it's a better model for what you're converting. A char would also let you use switch statement.I was going to say this as well but you beat me to it.
@OP, you really should use char for this. You're unnecessarily taking each char, converting it to a string, and working with the single-character string. That's not very efficient.

Problem with Character Codes...
For some reason this just isn't working right. It works for
some characters, like "d" is character code 100, it works for 100
but if i put in 104, which is "h" it doesnt work! doesnt work 32
which is space or 33 which is !
here is my function...
public function illegalCharCheck(charCheck:String):void{
var i:int;
var len:int = charCheck.length;
for (i = 0; i < len; i++){
if (charCheck.charCodeAt(i) == 100){
Alert.show('Illegal Character!', 'Sign Up',
mx.controls.Alert.OK);
Ive tried putting the character being checked for in
different spots in the string(which shouldnt matter).
So far it has not worked with anything other than 100, but
i've only tried like 10 or so. It should work for all of them!
Does anyone have any idea what is going on here?
Also.. Can i separate the character codes with commas so that
i can check them all in one if statement (there are a lot), or do i
need different if statements for each.. or use a switch statement.
That part isn't really clear to me for some reason...
Thanks.got it... i had the string being imported from
newUserNameInput.toString(); instead of newUserNameInput.text
private var illegalChars:Array = new Array(32, 33, 34, 35,
36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 58, 59, 60, 61, 62,
63, 64, 91, 92, 93, 94, 95, 96, 123, 124, 125, 126)
public function illegalCharCheck(charCheck:String):void{
var i:int;
var i2:int;
var len:int = charCheck.length;
var illegalTally:int = 0;
var illegalLen:int = illegalChars.length;
debug1.text='';
for (i = 0; i < len; i++){
for (i2 = 0; i2 < illegalLen; i2++){
if (charCheck.charCodeAt(i) == illegalChars[i2]){
debug1.text=debug1.text+charCheck.charCodeAt(i)+' ';
illegalTally++;
if (illegalTally>0){
debug1.text=debug1.text+' tally='+illegalTally;
Alert.show('Illegal Character! ', 'Sign Up',
mx.controls.Alert.OK);
works like a charm. -
Please Help: A Problem With Oracle-Provided 'Working' Example
A Problem With Oracle-Provided 'Working' Example Using htp.formcheckbox
I followed the simple steps in the Oracle-provided example:
Doc ID: Note:116534.1
Subject: How to use checkbox in webdb for bulk update using webdb report
However, when I select a checkbox and click on the Update button, I get a "ORA-01036: illegal variable name/number" error. Please advise. This was a very promising feature.
Fred
Below are step-by-step instructions provided by Oracle to create this "working" example:
How to use a checkbox in WEBDB 2.2 report for bulk update.
PURPOSE
This article shows how checkbox can used placed on WEBDB report
and how to use it.
SCOPE & APPLICATION
The following example to guide through the steps to create a working
example of this.
In this example, the checkbox is used to select the records. On clicking
the update button, the pl/sql procedure is called which will update col1 to
the string 'OK'.
After the update is done, the PL/SQL procedure calls the report again.
Since the report only select records where col1 is null, the updated
records will not be displayed when the report is called again.
Step 1 - Create Table
From Sqlplus, log in as scott/tiger and execute the following:
drop table chkbox_example;
create table chkbox_example
(id varchar2(10) not null,
comments varchar2(20),
col1 varchar2(10));
Step 2 - Insert Test Data
From Sqlplus, still logged in as scott/tiger , execute the following:
declare
l_i number;
begin
for l_i in 1..50 loop
insert into chkbox_example values (l_i, 'Comments ' || l_i , NULL);
end loop;
commit;
end;
Step 3 -Create SQL Query based WEBDB report
Logon to a WEBDB site which has access to the database the above tables are created.
Create a SQL based Report.
Name the report :RPT_CHKBOX
The select statement for the report is :
select c.id, c.comments, c.col1,
htf.formcheckbox('p_qty',c.id) Tick
from SCOTT.chkbox_example c
where c.col1 is null
In Advanced PL/SQL, (REPORT, Before displaying the form), put the following code
htp.formOpen('scott.chkbox_process');
htp.formsubmit('p_request','Update');
htp.br;
htp.br;
Step 4 - Create a stored procedure in the database
Log on to the database as scott/tiger and execute the following to create the
procedure.
Note: Replace WEBDB to the appropriate webdb user for your installation.
In my database, I had installed webdb using WEBDB username, hence user webdb owns
the packages.
create or replace procedure chkbox_process
( p_request in varchar2 default null,
p_qty in wwv_utl_api_types.vc_arr ,
p_arg_names in wwv_utl_api_types.vc_arr ,
p_arg_values in wwv_utl_api_types.vc_arr
is
i number;
begin
for i in 1..p_qty.count loop
if p_qty(i) is not null then
begin
update chkbox_example
set col1 = 'OK'
where chkbox_example.id = p_qty(i);
end;
end if;
end loop;
commit;
/* To Call Report again after updating */
SCOTT.RPT_CHKBOX.show
(p_request=>'Run Report',
p_arg_names=>webdb.wwv_standard_util.string_to_table2(' '),
p_arg_values=>webdb.wwv_standard_util.string_to_table2(' '));
end;
Summary
There are essentially 2 main modules, The WEBDB report and the pl/sql procedure (chkbox_process)
A button is created via the advanced pl/sql coding which shows on top of the report. (The
button cannot be placed at the bottom of the report due to the way WEBDB creates the procedure
internally)
When any button is clicked on the report, it calls the pl/sql procedure chkbox_process.
The procedure is called , WEBDB always passes the parameters p_request,p_arg_names and o_arg_values.
p_qty is another parameter that we are passing additionally, This comes from the checkbox created
using the htf.formcheckbox in the report select statement.
The pl/sql procedure calls the report again after processing. This is done to
show how to call the report.
Restrictions:
-The Next and Prev buttons on the report will not work.
So it is important that the report can fit in 1 page only.
(This may mean that you will not select(not ticked) 'Paginate' under
'Display Option' in the WEBDB report. If you do this,
then in Step 4, remove p_arg_names and p_arg_values as input parameters
to the chkbox_process)If your not so sure you can use the instanceof
insurance,
Object o = evt.getSource();
if (o instanceof Button) {
Button source = (Button) o;
I haven't thoroughly read the thread, but I use something like this:if (evt.getSource() == someObjRef) {
// do that voodoo
]I haven't looked into why you'd be creating a new reference... -

Problem with php code. Please help!
Hello!
I'm using the following syntax to bring content into my
websites' layout template:
Code:
<?php //check in the root folder first
if(file_exists('./' . $pagename . '.php'))
include './' . $pagename . '.php';
//if it wasn't found in the root folder then check in the
news folder
elseif(file_exisits('./news/' . $filename . '.php'))
include './news/' . $pagename . '.php';
// if it couldn't be found display message
else
echo $pagename . '.php could not be found in either the root
folder or the news folder!';
} ?>
What it's essentially saying is, if you can't find the .php
file in the _root folder, look for it in the /news/ folder.
It works perfectly if loading something from the _root folder
but I get an error if I need to bring something from the /news/
folder.
Can anyone see any potential problems with my code?
Thank you very much and I hope to hear from you.
Take care,
MarkI've never seen the code written like that before, but I'm
assuming it's
legal?
Perhaps try:
<?php
$newsroot = $_SERVER['DOCUMENT_ROOT']."/news";
if (!file_exists("$pagename.php")) {
elseif (!file_exists("$newsroot/$pagename.php")) {
else
Or the other thing you can try is replacing the elseif
statement with:
elseif (!file_exists("news/$pagename.php"))
If not - I'm sure Gary will be on here soon...

Vector, what is the problem with this code?
Vector, what is the problem with this code?
63 private java.util.Vector data=new Vector();
64 Vector aaaaa=new Vector();
65 data.addElement(aaaaa);
74 aaaaa.addElement(new String("Mary"));on compiling this code, the error is
TableDemo.java:65: <identifier> expected
data.addElement(aaaaa);
^
TableDemo.java:74: <identifier> expected
aaaaa.addElement(new String("Mary"));
^
TableDemo.java:65: package data does not exist
data.addElement(aaaaa);
^
TableDemo.java:74: package aaaaa does not exist
aaaaa.addElement(new String("Mary"));Friends i really got fed up with this code for more than half an hour.could anybody spot the problem?I can see many:
1. i assume your code snip is inside a method. a local variable can not be declare private.
2. if you didn't import java.util.* on top then you need to prefix package on All occurance of Vector.
3. String in java are constant and has literal syntax. "Mary" is sufficient in most of the time, unless you purposly want to call new String("Mary") on purpose. Read java.lang.String javadoc.
Here is a sample that would compile...:
public class QuickMain {
public static void main(String[] args) {
java.util.Vector data=new java.util.Vector();
java.util.Vector aaaaa=new java.util.Vector();
data.addElement(aaaaa);
aaaaa.addElement(new String("Mary"));

Facing problem with the code for sending an .xls attachment via email, a field value contains leading zeros but excel automatically removes these from display i.e. (00444 with be displayed as 444).kindly guide .
Hi Chhayank,
the problem is not the exported xls. If you have a look inside with Notepad or something like that, you will see that your leading zeros are exported correct.Excel-settings occurs this problem, it is all about how to open the document. If you use the import-assistant you will have no problems because there are options available how to handle the different columns.
Another solution might be to get familiar with ABAP2XLS-Project. I got in my mind, that there is a method implemented, that will help you solving this problem. But that is not a five minute job
~Florian -
Can anyone say the problem with the attached code. When I run the program, only, maximize, minimize and close options are viewable and nothing else.

Problem with the Code in exercise 1.2
In this exercise:
http://www.adobe.com/devnet/flex/pdfs/exercise1.2.pdf
the first part is easy. Then you are instructed to go to the
Debug
Perspective and set a breakpoint that is below the function
you defined, but
ahead of the variable array.
You are shown that the variables window is populated in debug
view ..but
this is just not true. I did this myself .. and then I did it
again by
copying and pasting the code directly from the PDF into the
application and
I got the same result. The application is halted with an
empty variables
window. The example says it should be populated.
I suspect the problem is that the breakpoint was set too
early .. but it is
where it is supposed to be. Is my problem the example (my
code is identical
.. has to be since the second try is copied) or is my problem
the debug
player? I have always had problems with debugging in Flex.
Thanks!
NancyHi,
Flex Builder 3 and Firefox 3 indeed do work together.
But there are some issues when certain extensions are used:
See
http://bugs.adobe.com/jira/browse/FB-13064
which led to a bug being filed against Firefox:

Problem with ALT codes on Apple Wired Keyboard
May I just note, I have posted this in the "Boot Camp" forum, but run the normal Windows 7 on my computer. I was unable to find a forum purely for Apple hardware.
I am using a Apple Wired Keyboard (MB110B/B) -- British-bought -- on a Windows 7 PC, and I are having some issues with ALT codes. The array of symbols I have to type (pi, sigma, etc) becomes tiresome to insert via the Character Map (on Win7). Basically, entering "alt" (left handside) then 227 does not insert "π" but rather "Ò". alt + 228 (Σ) inserts õ
I don't know if this problem is common for Apple keyboard users on Windows, but is there a way to alter this.
Thanks, Jordan.For a third opinion, be cautious of using a dishwasher as the temperature can get pretty high. If the spill is on the 456 on the number pad, you can try holding the keyboard vertically, soak just that part in distilled water for several minutes to disolve the spill material. Run some denatured (rubbing) alcohol over the numpad, then dry with a hair dryer.
You could also try to remove the key caps...slip dental floss under the key caps in two loops, one from the top one from the bottom. Pull the key caps off one at a time, the wipe the area clean...see if there is any material sticking that needs to be cleaned off.
I do not know what keyboard you have or how it does the switching, but most keyboards today do not use mechanical switches. The switches are sealed capacitance switches so if you clean all the material from the keyboard it may work again.
Or, if you don't feel like going to this much trouble, a visit to your friendly Apple Retailer to purchase a new one may be a good idea. -
Problem with character set (ubuntu linux)
hello everyone.
I 'have already installed oracle-xe-universal_10.2.0.1-1.1_i386 in ubuntu.
The problem is that greek characters from the db appear like ??????.
How can i set the right nls_lang character set to solve the problem in ubuntu linux?
Thank you in advance!Character code point translation is in the realm of the client, try setting NLS_LANG environment variable.
If your client programs handle UTF8, as do many linux utilities, that is the best choice, set your <language>_<locale>.<characterset>, i.e.
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
Or french_france, or german_germany ... depends on the locale you want to use. Try a `putty` session to the host, the terminal can be set for many different character sets, i.e. ISO8859-<n> a.k.a. the WE8<n> or Western European, UTF, etc. under Window/Translation.
Try a few select ... from dual; statements in sqlplus with a literal, and different unicode values- the unistr() and dump() functions can come in quite handy.
select unistr('\ac20 euro' ) from dual;
... € euro ...
select dump( unistr('\ac20 euro' ) ) from dual;
... <ascii codes for the character values> ...
select dump( unistr('\ac20 euro' ),16 ) from dual; -- this one for hex dump -
Problem with character set UTF-16 LE
Hello.
There were difficulties with character set change, using function convert ()
The matter is that in the list v$nls_valid_values the character set AL16UTF16LE does not appear, during too time the inquiry is successfully carried out
convert ([some-national-characters], ' CL8MSWIN1251 ', ' AL16UTF16LE ').
But at giving on an input of the data stored in CLOB, there is an error "a character set is not supported"
What are possible ways of the decision of a problem?You can try to use DBMS_LOB. SUBSTR to access LOB data like in the following example:
SQL> select * from v$version;

Problem with JavaScript code in Page Attributes, modal popup...
Hello all!
I'm encountering a problem with a modal popup I wrote in JavaScript.
h3.
The situation*
A user sees an interactive report with rows that are clickable, so these rows are links. Upon clicking the name of something in a row, some items get a certain value and a modal popup shows on the screen. In this modal popup, there are details regarding that particular row the user has clicked, but the problem_ here is...
The modal popup closes itself only seconds after it has been opened.
This must be because I've probably made a mistake somewhere in my code, but I just can't figure out where... It also appears that when I click on a row link, the popup shows, but the progress bar of my toolbar seems to show a loading bar (as if I refreshed the page).
h3.
My code*
This code is located in the _"Function and Global Variable Declaration"_ part, under the _"JavaScript"_ tab. Code is in the _"Page Attributes"_ of my page 24.
function showhide(x){
$x('REGION1').style.display = ( x == 'REGION1') ? 'block' : 'none';
$x('REGION2').style.display = ( x == 'REGION2') ? 'block' : 'none';
$x('REGION3').style.display = ( x == 'REGION3') ? 'block' : 'none';
$( function(){
$('#ModalForm').dialog(
modal: true,
autoOpen: false,
width: 500,
height: 350,
buttons:{ Close: function(){closeForm();}
function openForm()
$('#ModalForm').dialog('open');
function closeForm()
$('#ModalForm').dialog('close');
$(document).ready(function() {
$('a.temppop').click(function() {
openForm();
});This code is located in the _"Header Text"_ part, under the _"Header"_ tab. Code is in the _"Page Attributes"_ of my page 24.
<link rel="stylesheet" href = "http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/base/jquery-ui.css" type="text/css" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js"> </script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.js"> </script>This code is located in the _"Column Link"_ part, you get there by going to the _"Report Attributes"_ of the region called _"Template overview"_ on page 24. This region is an interactive report.
Link Text: #FOODTEMPLATENAME#
Link Attributes: class="temppop"
Target: Page in this Application
Page: 24
Item 1, name: P24_MEALID; item 1, value: #MEALTYPEID#
Item 2, name: P24_TEMPLATEID; item 2, value: #FOODTEMPLATEID#So basically I call the function to open the modal popup by the class name. When a link with that class name in it is clicked, it opens the popup.
To remind you of the problem, the modal popup closes seconds after it has been opened. How do I fix this?
Thanks in advance.
