Can someone tell me what's wrong with this method

public boolean drop(int col, int piece) {

 }it always asks that I need to return something, what should I do??

Can someone tell me what's wrong with this LOV query please?

This query works fine..
select FILTER_NAME display_value, FILTER_ID return_value
from OTMGUI_FILTER where username = 'ADAM'
But this one..
select FILTER_NAME display_value, FILTER_ID return_value
from OTMGUI_FILTER where username = apex_application.g_user
Gives the following error.
1 error has occurred
* LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
Thanks very much,
-Adam vonNieda

Ya know, I still don't know what's wrong with this.
declare
l_val varchar2(100) := nvl(apex_application.g_user,'ADAM');
begin
return 'select filter_name display_value, filter_id return_value
from otmgui_filter where username = '''|| l_val || '''';
end;
Gets the same error as above. All I'm trying to do is create a dropdown LOV which selects based on the apex_application.g_user.
What am I missing here?
Thanks,

Can someone tell me what's wrong with my router?

i was just using my router half-hour ago and it was working fine......i come back on a little bit and it is not working anymore........my wlan and dmz light in front of my WRT54G router won't light up and it keeps telling me that my connection is limited...i already reset both router and cable modems like 100 times already..is there any way i could fix this?

okay... if you are using cable internet connection, try restting the router back to factory default settings by pressing reset butoon on the back panel of router, power cycle the n/w by unplugging power cable of router and modem, wait for couple of minutes and power up the modem first once modem is rebooted power up the router, check internet works or not, if still doesn't work let me know which internet service are you using also tell me version no of WRT54G router so that i can tell you step by step configuration of router...

Can someone tell me what's wrong with my threading code

I got some code from a Java book on how to create a simple threading application. This is the exact code from the book but for some reason it gives me an error that non-static variables can not be referenced from static content. How can I reword this to work?
<CODE>
package multithread;
import java.io.*;
import java.util.*;
public class MultiThread {
class CountDownEven extends Thread {
public void run() {
for (int i = 6; i > 0; i -= 2) {
System.out.println(this.getName() + " Count" + i);
Thread.yield();
class CountDownOdd extends Thread {
public void run() {
for (int i = 5; i > 0; i -= 2) {
Thread.yield();
public static void main(String[] args) {
try {
CountDownEven count1 = new CountDownEven();
CountDownOdd count2 = new CountDownOdd();
count1.start();
count2.start();
catch (Exception e)
</CODE>

One possible solution:public static void main(String[] args) {
 try {
 MultiThread m = new MultiThread();
 CountDownEven count1 = m.new CountDownEven();
 CountDownOdd count2 = m.new CountDownOdd();
 count1.start();
 count2.start();

Says the error is "filelist is not recognized". on line 14. I thought I had fully defined 'filelist' on line8
I thought filelist was a one-D array variable.
Peterkal

Also, in lines 8 and 9 you use a variable called "filelist" but in lines 13 and 14 you call it "fileList" (notice the capital-L).
JavaScript is case-sensitive, so you must be consistent with your variable names throughout.

4.3.5 is the current version, so that is the version that iTunes will download, not 4.3.3

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.

What is wrong with this method?

When i try to compile
     public double generateXPos()
          double d = Math.random()*100;
          if (d > 37.0)
               generateXPos();
          else
               return d;
it says: "this method must return a result of type double", bit doesn't it do so?!?
By the way I am using eclipse v. 3.0.1
Thanks in advance,
Floesch

Because i could not think of this way of doing that,
for i am a bloody beginner.A "bloody" beginner? You should wipe yourself off with a damp cloth.
Could you tell me how to do it then?I can point you in the right direction. The first line of your method generates a number between 1 and 100. Either you intentionally wrote it to work that way, in which case you should very easily be able to re-write it to generate a number between 1 and 37 instead; Or, perhaps you copied it from somewhere else not understanding what it does, in which case you should take the time to understand it before continuing.
Either way, as you now know that the first line generates a number between 1 and 100, you should be able to make a good guess at how to change it so that the generated number is between 1 and 37. If nothing at all springs to mind here, then I really genuinely do believe you aren't the kind of person that's gonna do well as a programmer.

Can anyone tell me what's wrong with my queue or producer consumer loop?

A Labview engineer helped me with the overall structure of my program, necessitated by the fast data sample rate and post processing requirements. He recommended the producer/consumer loop and using one of the example files (Cont Acq graph voltage - int clk) to do the actual data acquistion. So I put together the loop and go my two channels of data acq going in the producer loop. However, nothing's getting picked up in the consumer loop and none of my data gets displayed over there.
Anyone care to take a look at it and let me know what I'm doing wrong?
Solved!

Your Enque Element should be inside the while loop where you aquire the data. As it is now, the data has to stop being aquired before you send the last set of aquired data.

Could someone tell me what is wrong with AS 3.0

I'm moving a movie clip that is off the stage and acts as a
popup window to the visible area. then i'm animating it to cover
the entire stage size. then moving a box in.
This thing is very very buggy. It works about 70% of the time
correct. I have the variables of the size traced and they are
ALWAYS correct. However the animation doesn't reflect this.
Sometime the box won't animate the width, sometimes the height, and
sometimes it doesn't show up at all. What is going on?
Thanks!

your code is correct (with the assumptions given above). you
can test it outside your current project and verify that it works.
i just finished a project where i ported an as2 application
to as3. that application used many tweens and i kept them in the
as3 version. i did run into some problems with the tweens that i
solved by giving the tweens different names.
for example, if you call layersWindowIn() twice, with the
second call occurring before the first has completed, you'll
probably run into problems. is that when the problems occur?

Can anyone tell me what is wrong with the simple sql?

Hi,
I have a simple SQL (see attached). It returns records when it does not include the Order By sorting clause. However, if it includes the Order By clause, Oracle says no data found. Anyone can give me some ideas what could cause the problem?
Thanks in advance.

FROM work_package wp, episodes e, item_header ih, patients p, codes c, station_element se, station_data sd

and e.episode_type = c.code_value
and wp.asgn_station_key = se.item_key

While working in multi camera editing in FCP X, having only 2 angles, after cutting for 30 minutes, the editing starts slowing down gradually until it becomes unbearably slow. Can someone tell me what is wrong?

This is the second time I am using the multicamera editing mode. The first time I used it with 2 angles of HD 720p and it worked perfectly. This time I am working with standard definition vodeo and is giving me this problem.

This is my pet checklist for questions regarding FCP X performance.
Make sure you're using the latest version - FCP X 10.0.3 runs very well on my 2009 MacPro 2 x 2.26 GHz Quad-Core Intel Xeon with 16 GB RAM and ATI Radeon HD 5870 1024 MB. I run it with Lion 10.7.3.
First, check that you have at least 20% free space on the Hard Drive that your System and your Media, Projects and Events are on.
Check the spec of your Mac against the system requirements:
http://www.apple.com/finalcutpro/specs/
Check the spec of your graphics card. If it's listed here, it's not suitable:
http://support.apple.com/kb/HT4664
If you are getting crashes, there is some conflict on the OS. Create a new (admin) user account on your system and use FCP X from there - if it runs a lot better, there's a conflict and a clean install would be recommended.
Keep projects to 20 mins or less. If you have a long project, work on 20 min sections then paste these into a final project for export.
Create Optimised media - most camera native files are highly compressed and need a great deal of processor power to play back - particularly if you add titles, filters or effects. ProRes 422 takes up much more hard drive space but is very lightly compressed. It edits and plays back superbly.
If you are short of drive space, use ProRes 422 Proxy (FCP X Preferences > Playback) - but remember to select 'Original or Optimised Media' just before you export your movie, otherwise it will be exported at low resolution.
Hide Audio Waveforms at all times when you don't need them (both in Browser and Storyline / Timeline). They take up a lot of processor power. (Use the switch icon at the bottom-right of your timeline to select a format without waveforms if you don't need them at the moment, then switch back when you do).
Create folders in the Project and Events libraries and put any projects you are not working on currently, in those folders. This will help a lot.
Move your Projects and Events to a fast (Firewire 800 or faster) external HD (make sure it's formatted OS Extended - with journaled on or off) and run from there.
Unless you cannot edit and playback without it, turn off Background Rendering in Preferences (under Playback) - this will help general performance and you can always render when you need to by selecting the clip (or clips) and pressing Ctrl+R.
The biggest single improvement I saw in performance was when I upgraded the RAM from 8 GB to 16.
