IDL tutorial help needed

I'm trying to recreate the example within the hello world idl example:
http://babbage.clarku.edu/java/docs/guide/idl/jidlExample2.html
Everything seems to work fine up until the actual call to hello.sayHello() in the client, where I get a null pointer exception. I was able to load orbd but only if I set the -port flag to a port other than it's default. Do I need to indicate this in the call from the client? I started orbd like this:
orbd -ORBInitialPort 11111 -port 1039
Yes, I realize that I have also changed the ORBInitialPort from 1050 to 11111 and I have reflected that in the client. I just wasn't sure how to (or even if it was necessary to) indicate the activation port (indicated by -port).

Ok, I figured it out. I had played around with some of the files that were generated with idlj. I was initially trying to use idlj with an idltojava example, not realizing that I was trying to use the persistent output of idlj with a transient example. It works much better if you know what your doing :o)

Href and target tags tutorial/help needed for use with an existing website

I have a website, (built through iweb), and an intro movie. I have spent a lot of time trying to understand the proper tags and how to use them without much luck. My goal is to have the homepage associated with my domain name load in a browser while at the same time have my intro movie open in a Quicktime Player window, play, and automatically close leaving the webpage visible. If anyone can point me to a tutorial or walk my through the process I would appreciate it.

Poster movie style. Requires QuickTime Pro:
Create an image (or a frame from your movie). This becomes the "poster". You could add text to it (Click to Play) in a graphic editor app to help your viewers or add text to the page under the image with these instructions.
Save this new file as poster.mov
It becomes the src="poster.mov" (source tag in the html code). Set its dimensions to fit your page layout.
Your "intro movie" will be your href="intro.mov" (href tag in the html code).
Open it with QuickTime Pro and then open the Movie Properties window. Click on the Presentation tab to see the choices. Automatically close option will close the QuickTime window. Automatically quit option will quit the running QuickTime Player app. This would be a better option as the browser should come back as the "front" application. You also want to check "auto play".
Use Save As (preserves fast start feature) and name this file intro.mov
In your html code for the QuickTime files you need to set target="quicktimeplayer" (this launches the QuickTime Player app instead of using the browser plug-in). It may also help if you use the full URL to both files in each tag (http://myserver.com/foldername/intro.mov).
One of mine as an example. It uses automatically close window:
http://homepage.mac.com/kkirkster/mycareerfuture/
View the source code to see the tag structure. My page uses javascript instead of the older object/embed tag code.

Flash Matrix Code Tutorial Help Needed

Please could someone help me out with this Flash problem, I would really appreciate it.
I have followed the guide at this link to create a matrix code effect. The matrix code font file is available to download from this site also (mCode15).
Once I get this file up and running and understand how it works, I'm going to tweak it somewhat to suit my needs.
I am, however, experiencing some problems getting it to work as described in the tutorial. I have followed the tutorial to the letter, but when the flash movie file runs, only the glyph symbol that I used to create the_one and one_pod movie symbols is displayed in the code that scrolls down screen. I have embedded the font the way it describes and even added it to the library and set it to export for actionscript using the linkage option. But the matrix code that rains down is still only one symbol which never changes.
Please please help me out with this as I'm slowly losing my sanity trying to figure it out. I am using Flash CS3 on a PC to do this and the file is set up up as action script 2.0.

hi
try asking in the AS2 forum; they will be better placed to help you - and post some of your code too rather than a link (you cant expect us to do all the work for you )

Many thanks for any help you can provide.
The Action Script code from the site is included below, this is pasted into the 1st frame.

this.delay--;
} else {
// Yes, then reset the character position.
this.ind = 0;// Reset the delay before next pulse.
this.delay = this.myCodes.length;}}}}

When you dynamically add content, it has no home on the timeline unless you anchor it in one. If you were to manually place an empty movieclip on the timeline in the lowest layer and then and then create the matrix stuff in there then you would have it living in the background.
Try creating such a movieclip, located in the upper left corner of the stage and assign it an instance name of "theMatrix"
Then remove the following lines from your existing code (which is otherwise creating that mc dynamically)...
// Create an empty Movieclip to hold the Matrix.theMatrix = createEmptyMovieClip('MatrixCode',1);
That should be all you need to do.

Navigation Tutorial Help Needed

I am following an online tutorial to build a horizontal menu bar in AS3.
In the tut, they are using MovieClips, but for what I want to achieve I am using buttons.
Here is their code.
function navOverF(event:MouseEvent):void{
event.target.filters = [navBtnGlow];
navBar_mc.setChildIndex(event.target as MovieClip, 1);
dropMenus_mc.gotoAndStop(navBar_mc.getChildAt(1).name);
trace("We are rolling over..." + navBar_mc.getChildAt(1).name);
I have worked out that the issue is in line three "(event.target as MovieClip, 1)", but how do I change this code to work with buttons?
Any help would be much appreciated.
Cheers
Dave

Thanks for the help guys.
I received a solution from another forum, and that was replacing MovieClip with DisplayObject.
Thanks again.

IdL big time help needed

I have a program and I would like 2 split it into a client-server system using IDL, I would appreciate any tips given (I�m very new to IDL). At the moment it takes input from the user, in the form of a user name and password, and check against a database. I would like to have the input on the client and the check of the database on the server, with eather an accept or refuse message sent back to the user.
import javax.swing.JOptionPane;
import java.sql.*;
public class log
public static void main(String[] args)
//client
String UserId;
String Password;
UserId = JOptionPane.showInputDialog("Eneter your UserID"); // were the user eneters his User
Password = JOptionPane.showInputDialog("Eneter your Password");//were the user eneters his Password
//server
try {
//have to be in a try catch block
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
//setting up the database
String dataSourceName = "cw2";
String dbURL = "jdbc:odbc:" + dataSourceName;
Connection con = DriverManager.getConnection(dbURL, "","");
//setting up the database
Statement stmt = con.createStatement();
String query = "SELECT Username , password FROM LOG"; // find the values and printen them out
ResultSet rs = stmt.executeQuery(query);
String s, n;
boolean flag = false;
while(rs.next())
s = rs.getString("UserName");
n = rs.getString("password");
if(s.equals(UserId) && n.equals(Password))
flag = true;
System.out.println( " access allowed " );
//grant access
break;
} //if
} //while
if(flag == false)
System.out.println( " access refused " );
//deny access
catch (Exception err) {
System.out.println("ERROR: " + err);
System.exit(0);

You might want to take a look at the examples in
http://java.sun.com/j2se/1.4.1/docs/guide/idl/index.html
and adapt one of the IDL interfaces to your needs.
Something like
module myapp
interface validator
boolean validate_user(in wstring username, in string password);
Note that this won't have any security for your password on the wire.
I just did a quick search to see if I could find a happy IDL tutorial, but I guess I usually use the main CORBA spec, actually.

Some J2ME midlets doubts!! help needed urgently!!!

Hi,
I am currently working in a company where it does wireless technology like WAP and I am assigned a task of creating a screensaver midlet. I have some doubts on the midlets.
1) How do i use a midlet suites? From what I heard from my colleagues & friends, a servlet is needed for midlets to interact with one another. is it true?
2) How do I get the startin midlet to take note the phone is idling so that the screen saver midlet can be called?
Help needed urgently... if there is any source codes for me to refer to would be better... Thanks...
Leonard

indicates that MIDlet suites are isolated (on purpose) from each other, so you can't write over another one's address space.
Also, I believe (at least on cell phones) that you have to specifically enter the Java Apps mode; unless you do the app won't execute. If you are in Java apps mode and a call comes in, the cell's OS puts the Java app currently executing on "Pause" mode and switches back to phone mode.
Not sure if you will be able to have a Java app do that automatically.
BTW why do you need a screensaver on an LCD display? Is it really intended to show an advertisement?
Download and real all the docs you can from Sun, once you get over the generic Java deficiencies MIDlet's aren't that hard.

IDL Tutorial Error

I am currently following the at http://java.sun.com/j2se/1.4.1/docs/guide/idl/tutorial/GScompile.html and when I run the command :
start /B java -classpath c:\hello;c:\hello\helloapp HelloServer -ORBInitialPort 1050 -ORBInitialHost localhost
it throws up an error :
Exception in thread "main" java.lang.NoClassDefFoundError: org/omg/PortableServer/Servant
I have checked the FAQ's and this seems a common problem. As per the FAQ I have included the classes into the classpath (as can be seen in the command line). I have followed the tutorial strictly, and up to this point every ran well ie all clean compiles etc.
My current java version is SE 1.3.1_01 using Java Hotspot client Vm (mixed mode) on Windows 2000
All help would be greatly appreaciated at this point.
Thanks

Business rule: a combination consists of a maximum of 4 subjects (must contain)
and the user is less relevant to a COMB_NAME(name of combinations) but user need
the subjects contained in combinations
i need the following output
COMB_ID COMB_NAME SUBJECT1 SUBJECT2      SUBJECT3      SUBJECT4
383     S1     Biology Chemistry      Computer Science Physics
384     S2     Chemistry Computer Science Mathematics Physics

COMB_ID     subjects
383           Biology,Chemistry,Computer Science,Physics
384           Chemistry,Computer Science,Mathematics,Physics
you can use any of the COMBINATION table(either (2) or (3))
and i want to know
1)which design is good in this case
(i think SUB_ID1,SUB_ID2,SUB_ID3,SUB_ID4 is not a
good method to link with same table but if 4 subjects only(and must) comes
detail table is not neccessary )
now i am achieving the result by program-coding in C# after getting the rows from oracle
i am using oracle 9i (also ODP.NET)
i want to know how can i get the result in the stored procedure itsef.
2)how it could be designed in any other way.
any help/suggestion is welcome
thanks for your time --Pradeesh

Well I forgot the table-alias, here now with:
SELECT C.COMB_ID
, C.COMB_NAME
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID1) AS SUBJECT_NAME1
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID2) AS SUBJECT_NAME2
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID3) AS SUBJECT_NAME3
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID4) AS SUBJECT_NAME4
FROM COMBINATION C;
As you need exactly 4 subjects, the columns-solution is just fine I would say.

Hi all help needed I have a canon 40D. I am thinking of buying a canon 6D.
But not sure that my lenses will work.
I have a 170mm/ 500mm APO Sigma.
A 10/20 ex Sigma HSM IF.
And a 180 APO Sigma Macro or do I have to scrap them and buy others.
ALL Help will be greatly received. Yours BRODIE

In short, I love it. I was going to buy the 5DMark III. After playing with it for a while at my local Fry's store where they put 5DMII, 5DMIII and 6D next to each other, using the same 24-105L lens, I decided to get the 6D and pocket the different for lens later.
I'm upgrading from the 30D. So I think you'll love it. It's a great camera. I have used 5DMII extensively before (borrowing from a close friend).
Funny thing is at first I don't really care about the GPS and Wifi much. I thought they're just marketing-gimmick. But once you have it, it is actually really fun and helpful. For example, I can place the 6D on a long "monopod", then use the app on the phone to control the camera to get some unique perspective on some scenes. It's fun and great. GPS is also nice for travel guy like me.

Help needed! Raid degraded again!

Hi!
Help needed! I hava made bootable RAID with two S-ATAII 250Gb HDD and its not working! Every now and then at bootup I get a message RAID -> DEGRADED... Must be seventh time! Rebuild takes its own time!
What am I doing wrong!
T: Ekku
K8N Neo4 Ultra
AMD 64 4200+
2 Gb RAM
2 x 250 Gb HDD (Maxtor)
nVidia RAID (in mb)
P.S. I wery SORRY with my poor language!

I'm going to blame the nVRAID because I've seen issues with it in the past. If your motherboard has another non-nVidia RAID solution, use that instead. Using the nVidia SATA ports as BASE or JBOD is fine and dandy but RAIDing always had issues. It's not even a driver issue I think it's just instability. Latest drivers and even boxed drivers never helped. Granted, some will report success with their rig. But on a professional level I've seen nForce issues on different motherboards and different hard drives that had RAID disaster stories.
Good luck and if you don't have another RAID solution, my suggestion would be to buy a dedicated RAID controller card.

Have you tryed Google ? really.. your question is inrelevant. No need to reply indeed.
Why do you come here asking this question anyway ? is it becouse you have a MSI gfx card ? and the adapter has nothing to do with this ?
You think you can come in here yelling.. thinking we have to put up with it and accept your style of posting. This is not a MSI tech center.. it's a user to user center.. Your question has nothing to do with MSI relavant things anyway's.
