What's wrong with this button code

Dear All,
I am trying to set up a button handler for many buttons
rather just one. The
intention of this code is to say if I press Load1 to Load40
that button and
only that button's alpha should change to 50%. This code
makes them all 50%
alpha when the frame loads rather than on the onPress event.
Can someone please help me out with this one?
i = 0;
while (i<40) {
this["Load"+i].onPress = btnEvaluate(this["Load"+i]);
++i;
function btnEvaluate(target_btn:Button) {
target_btn._alpha = 50;
Thanks again.

kglad,
Thanks again. What would this group do without your help.

Can't gotoAndStop ...what's wrong with this button code?

Hi,
I'm totally stumped as to why I can't navigate to another frame.
I have put 2 days into this simple problem now and I'm ready to give up and go back to AS2.
Please help!
I'm using CS4; publish settings AS3, 10.0
I have a button on frame 2 that should take me to frame 3 when clicked.
(So far I've tried a hundred different ways but I don't get to frame 3...)
Different things I tried...
> Creating the button dynamically from the library...
> Inserting it statically from the library on frame 2...
> referencing the mainTimeline through a variable...
> wrapping the gotoAndStop action in another function...(if placed directly on the timeLine the movie correctly goes straight to frame 3)
> naming frame 3...
> using 'nextFrame' instead of 'gotoAndStop'...
etc..
In most cases I don't get an error in the output panel and no compiler error either; it just doesn't work!!!
(Just stays on the same frame after I click the button)
Here's the code I think should work; but doesn't:
function moveTo3 (event:MouseEvent):void {
trace("button_clicked"); // always traces correctly; but movie does not go to frame 3 !!!
gotoAndStop(3);
f_btn.addEventListener(MouseEvent.CLICK, moveTo3);
WHAT AM I MISSING HERE?
Thanks in advance ...

Hi Ned,
I have to run out and don't have the time to deal with it right now but you're RIGHT.
I do have an 'onEnterFrame' listener on frame 1 !
It's doing some animation with a symbol and I don't think I removed the listener itself.
I just set the object to null when it reached [alpha:0].
THANKS!
I'll check it out as soon as I can but I really think you got me looking in the right direction now.
Thanks again,
Connor
(I'll post an update when I get back to it)

What's wrong with this simple code?

What's wrong with this simple code? Complier points out that
1. a '{' is expected at line6;
2. Statement expected at the line which PI is declared;
3. Type expected at "System.out.println("Demostrating PI");"
However, I can't figure out them. Please help. Thanks.
Here is the code:
import java.util.*;
public class DebugTwo3
// This class demonstrates some math methods
public static void main(String args[])
          public static final double PI = 3.14159;
          double radius = 2.00;
          double area;
          double roundArea;
          System.out.println("Demonstrating PI");
          area = PI * radius * radius;
          System.out.println("area is " + area);
          roundArea = Math.round(area);
          System.out.println("Rounded area is " + roundArea);

Change your code to this:
import java.util.*;
public class DebugTwo3
     public static final double PI = 3.14159;
     public static void main(String args[])
          double radius = 2.00;
          double area;
          double roundArea;
          System.out.println("Demonstrating PI");
          area = PI * radius * radius;
          System.out.println("area is " + area);
          roundArea = Math.round(area);
          System.out.println("Rounded area is " + roundArea);

What's wrong with this mini-code? (Trying to draw graphics).

Could someone please help me fix what's wrong the following test-program?:
package project;
import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class GraphicsTester extends JPanel
    JPanel thePanel = this;
    public void GraphicsTester()
        JFrame frame = new JFrame();
        frame.setSize(600,600);
        frame.add(thePanel);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    protected void paintComponent(Graphics g)
        super.paintComponent(g);
        g.drawRect(50, 50, 50, 50);
        System.out.println("Sup fool");
    public static void main(String[] args)
        GraphicsTester gt = new GraphicsTester();
        System.out.println("works2");
}Any help would be greatly appreciated!
Thanks in advance!

Also, all Swing code should be called from the Event Dispatch Thread. It probably isn't hurting much in your case. But, in the body of main, do this (instead of the comment, put what you currently have as the body of main):
EventQueue.invokeLater(
new Runnable()
      public void run()
          // Your current body of main.
});

What's wrong with this widget code?

Hi everyone,
(I hope this is a good place to put this) I'm trying to build a widget in Dashcode, and one of the things I want to do is run a system command (specifically "ps -ax"). I enabled command line access in the widget attributes, and I now have:
var processes = widget.system("/bin/ps -ax", NULL);
The problem is that "processes" is always undefined. I read on here that there's a bug that if the output is too long, then the variable is undefined. So I tried substituting the command with this:
var processes = widget.system("/bin/ls ~/", NULL);
When I run the command in Terminal, the output is minimal:
Desktop Documents Downloads Library Movies Music Pictures Public Sites
But when I try to run that in Dashcode, it still returns undefined. Am I missing something obvious here?

bump I'm still at a standstill with this. Any ideas?
Thanks!

What is wrong with this idoc code snip?

Hi all here's the code that's supposed to give me a default value for a metadata in check-in:
1. <$if dDocAccount like "test*"$>
2. <$dprDefaultValue="Test"$>
3. <$elseif userHasRole("TesterA") or userHasRole("TesterB")$>
4. <$dprDefaultValue="A or B"$>
5. <$elseif userHasRole("TesterC") or userHasRole("TesterD")$>
6. <$dprDefaultValue="C or D"$>
7. <$else$>
8. <$dprDefaultValue="Not A nor B nor C nor D"$>
9. <$endif$>
Now if I leave the code like that only the first 2 lines work meaning that if first condition fails then the whole code stops working even though line 3 is true... is there something wrong in just calling dDocAccount on its own? never seen that happen before.
If I change that first line for <$if *#active.* dDocAccount like "test*"$> then this first condition won't work but the rest (line 3+) does work!
please help!!

Hmmmm,
If your first two lines work if true then the issue is with the elseif lines right?
userHasRole("foo") returns true or false. Can you wrap userHasRole("foo") in an "isTrue()" function and test that way?
What about exploding the OR statement and writing a bunch of elseifs to see if it works that way.
The other thing you can do is to wrap your OR clause itself in parens
<$elseif ((userHasRole("foo")) or (userHasRole("bar")))$>
do stuff
<$endif$>
let us know what works for you

What is wrong with this trigger code?

Hi folks,
Just wondering whether I might be missing something here about Oracle 9i, that one of you might notice, either from the syntax perspective, or regarding a bug? The code below compiles in the database I have, but the trigger does not fire, and no data is being inserted into the tables. The trigger is owned by sys, and the insert statements are in dynamic sql because I don't want the trigger not to compile if ever the tables are deleted from the b1dev schema.
Incidentally, this same trigger works well on Oracle 10.2.1.0 and Oracle 11.1.0. Any feedback would be much appreciated.

I have taken out the 'commit' and have added the 'when others then null' exception clause, but I would imagine there is a better way to do it than this? I don't want to do an insert into another table either. With Oracle 11g, this gives me the compile time warning....

}i really need some assistance at the following areas of code :

and where this bean is then added to another bean abridgeresults (Type Results) as a List collection.
i get a null pointer exception when i try to retrieve the List from abridgeresults object of Type Results Bean.
i would really appreciate some assistance in this - i really need to go to sleep now - but cant until i solve this issue. - thanks all in advance.

below is exception outputed to tomcat log file.
it is thrown at the following line of code in the jsp that tries to get the List object :

Also, i dont understand why the servlet keeps on forwarding to the results.jsp when i even comment out the line of code to forward request oobject to results.jsp - i recompile copy it over original and restart tomcat - but still i get the null pointer exception in results_jsp - but i'm no longer forwarding anything to this jsp. --- i want to do some out.printline statemets in servelt to see some of the data from the query - but i cant as it just forwrads the request to results.jsp - how can i output the data to look at debug - i dont have a log4j logger setup and dont have IDE to be able to place break points - so wanted to just output stuff to browser to have a look at what was going on - but can't as just forwards request on ?

What's wrong with this small code?

hi, there,
I tried to compile the following code and get the error like:
Can't make static reference to non-static reference in line System.out.println(msg);
It is wired to me. Could somebody give a hint? Really appreciate!!!
Jianmin
import java.awt.*;
import java.awt.event.*;
public class fram extends Frame
String msg="hello";
public static void main(String arg[])
fram f=new fram();
Button b=new Button("Click");
b.addActionListener( new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println(msg);
f.add(b);
f.pack();
f.show();

Thanks a lot!!! it works.
msg is non-static, that is 'instance' variable,
and you can not acces it from static context. Simply
speaking you have to use b.msg, will not work
eather though

What is wrong with this code? on(release) gotoAndPlay("2")'{'

Please could someone tell me what is wrong with this code - on(release)
gotoAndPlay("2")'{'
this is the error that comes up and i have tried changing it but it is not working
**Error** Scene=Scene 1, layer=Layer 2, frame=1:Line 2: '{' expected
     gotoAndPlay("2")'{'
Total ActionScript Errors: 1 Reported Errors: 1
Thanks

If you have a frame labelled "2" then it should be:
on (release) {
    this._parent.gotoAndPlay("2");
or other wise just the following to go to frame 2:
on (release) {
     this._parent.gotoAndPlay(2);
You just had a missing curly bracket...

I can't figure out what's wrong with this code

First i want this program to allow me to enter a number with the EasyReader class and depending on the number entered it will show that specific line of this peom:
One two buckle your shoe
Three four shut the door
Five six pick up sticks
Seven eight lay them straight
Nine ten this is the end.
The error message i got was an illegal start of expression. I can't figure out why it is giving me this error because i have if (n = 1) || (n = 2) statements. My code is:
public class PoemSeventeen
public static void main(String[] args)
EasyReader console = new EasyReader();
System.out.println("Enter a number for the poem (0 to quit): ");
int n = console.readInt();
if (n = 1) || (n = 2)
System.out.println("One, two, buckle your shoe");
else if (n = 3) || (n = 4)
System.out.println("Three, four, shut the door");
else if (n = 5) || (n = 6)
System.out.println("Five, six, pick up sticks");
else if (n = 7) || (n = 8)
System.out.println("Seven, eight, lay them straight");
else if (n = 9) || (n = 10)
System.out.println("Nine, ten, this is the end");
else if (n = 0)
System.out.println("You may exit now");
else
System.out.println("Put in a number between 0 and 10");
I messed around with a few other thing because i had some weird errors before but now i have narrowed it down to just this 1 error.

hi,
but the upper limit is changing everytime you call the function recursively
so there should not be any problem(i suppose)
my intension is to get the unmatched elements of the two vectors
suggest me changes and thanks in advancce
ashok
The problems comes from the fact that you remove
elements for a Vector while iterating in a loop where
the upper limit as been set to the initial size of the
Vector.
You should use so while loops with flexible stop
conditions that would work when the size of the Vector
changes.
Finally: why don't you use Vector.equals() ?

What's wrong with this?HELP

What's wrong with this piece of code:
clickhereButton.addActionListener(this);
^
That's my button's name.
Everytime I try to complie the .java file with this code in it it says:
Identifier expected: clickhereButton.addActionListener(this);
^
Please help.

You must have that code in a method or an initilizer block... try moving it to eg. the constructor.

what's wrong with this SQL?

Hi, everyone:
when I insert into table, i use the fellowing SQL:
INSERT INTO xhealthcall_script_data
(XHC_CALL_ENDED, XHC_SWITCH_PORT, XHC_SCRIPT_ID, XHC_FAX_SPECIFIED)
VALUES (SELECT TO_DATE(HH_END_DATE||' '||HH_END_TIME,'MM/DD/YY HH24:MI:SS'), HH_SWITCHPORT, HH_SCRIPT,'N'
FROM tmp_healthhit_load WHERE HH_SCRIPT !='BROCHURE' UNION
SELECT TO_DATE(HH_END_DATE||' '||HH_END_TIME,'MM/DD/YY HH24:MI:SS'), HH_SWITCHPORT, HH_SCRIPT,'N' FROM tmp_healthhit_load WHERE HH_SCRIPT !='BROCHURE');
I always got an error like;
VALUES (SELECT TO_DATE(HH_END_DATE||' '||HH_END_TIME,'MM/DD/YY HH24:MI:SS'), HH_SWITCHPORT,
ERROR at line 3:
ORA-00936: missing expression
but I can't find anything wrong, who can tell me why?
thank you so much in advance

For starters, an insert select does not have a values clause.

...and why are you doing a UNION on the exact same two queries?
(SELECT TO_DATE(HH_END_DATE||' '||HH_END_TIME,'MM/DD/YY HH24:MI:SS') ,HH_SWITCHPORT ,HH_SCRIPT ,'N' FROM tmp_healthhit_load WHERE HH_SCRIPT !='BROCHURE' UNION SELECT TO_DATE(HH_END_DATE||' '||HH_END_TIME,'MM/DD/YY HH24:MI:SS') ,HH_SWITCHPORT ,HH_SCRIPT ,'N' FROM tmp_healthhit_load WHERE HH_SCRIPT !='BROCHURE');

Hi,
thank you for your answer, but the problem is, if I deleted "values" as you pointed out, and then execute it again, I got error like "ERROR at line 3:
ORA-03113: end-of-file on communication channel", and I was then disconnected with server, I have to relogin SQLplus, and do everything from beganing.
so what 's wrong caused disconnection, I can't find any triggers related. it is so wired?
I wonder if anyone can help me about this.
thank you very much

Hi,
acturlly what I do is debugging a previous developer's scipt for data loading, this script was called by Cron work, but it never can be successfully executed.
I think he use union for eliminating duplications of rows, I just guess.
thank you

Scratch the VALUES keyword then make sure that the select list matches the column list in number and type.
1 insert into marktest
2 (fld1, fld2, fld3, fld4, fld5)
3* select * from marktest
UT1 > /
16 rows created.

try this - just paste the code and give me the error- i mean past the entire error as it is if error occurs
INSERT INTO xhealthcall_script_data
(xhc_call_ended, xhc_switch_port, xhc_script_id,
xhc_fax_specified)
SELECT TO_DATE (hh_end_date || ' ' || hh_end_time, 'MM/DD/YY HH24:MI:SS'),
hh_switchport, hh_script, 'N'
FROM tmp_healthhit_load
WHERE hh_script != 'BROCHURE'
UNION
SELECT TO_DATE (hh_end_date || ' ' || hh_end_time, 'MM/DD/YY HH24:MI:SS'),
hh_switchport, hh_script, 'N'
FROM tmp_healthhit_load
WHERE hh_script != 'BROCHURE';

Hi, Jagan:
thank you very much for your answer.
but when I execute it, I still can get error like:
ERROR at line 1:
ORA-03113: end-of-file on communication channel
so wired, do you have any ideas?
thank you very much

And this one,
Aother question about SQL?
I thought I already told him to deal with
ORA-03113: end-of-file on communication channel
problem first.
There's nothing wrong (syntax wise) with the query. (of course when no "value" in the insert)

What is wrong in this java code?

Can someone please tell me what is wrong in this java code?

Please tell me if this can be written in a more simpler manner. Also please correct this code. I am tired after trying many times.

When I fix your error, compile and run it, I get this exception:
