\t problem with int

I have a question about the \t escape sequence. I am still learning but I can get it to work just fine in literal strings then when I try to use it with an int I keep getting illegal character \92. Here is what I am trying to do
class Display
public static void main(String args[])
int x = 5;
System.out.println("Number\tIts Double\tIts Triple");
System.out.println(x\t(x*2)\t(x*3);
x = x + 1;
System.out.println(x\t(x*2)\t(x*3);
So I am trying to a x, x's and x's triple to print but keep getting illegal character \92 coming up when I go to compile. Please help me figure this problem out as I have tried everything I can think of. Thanks for your help in advance

System.out.println(x\t(x*2)\t(x*3);WFT? \t only has meaning within a String!
try something like this
System.out.println("x\t(x*2)\t(x*3) = "+x+"\t("+(x*2)+")\t("+(x*3));

Programming problems with INT / FLOAT

I got a problem with datatypes float and int.
I'm just developing a c-program on HP-UX with the gcc-compiler. 'cause i have not ever been done an ORACLE-access before, i has started with the "cdemo2.c" - example from the oracle-demo-dircetory in version 8.0.4.
in the DB there's a column with NUMBER-TYPE, but when i call the oci-function (or what ever it is) "odescr()", the variable "scale" (which is supposed to differentiate between FLOAT_TYPE and INT_TYPE) always is set to "0". this variable should be set to anything else but "0" if a FLOAT_TYPE is detected, but it isn't.
what I do wrong ???
How can I know the exact datatype, when a NUMBER_TYPE in the DB appears ???
if there is a better way to realize an oracle-access in C, please don't wait to tell it to me
many thanks

You basically got it. Another approach is to always work on the rightmost digit; that way you'll always be dividing, mod'ing, or multiplying by 10.
You don't need to know the length of anything to use a for loop. Remember that a for loop has 4 parts: the initialization, the conditional, the "update", and the body. (There are probably more correct names for these that I can't recall right now.) The conditional and the update tend to be length checks and increments only because for loops are commonly used over arrays or strings, but they don't have to be.
Another hint: how do you know when you're done pulling the digits out of the source number? What is the value of the source number when you're done?

Problem with String to Int conversion

Dear Friends,
Problem with String to Int conversion
I am having a column where most of the values are numeric. Only 4 values are non numeric.
I have replaces those non numeric values to numeric in order to maintain the data type.
CASE Grade.Grade WHEN 'E4' THEN '24' WHEN 'E3' THEN '23' WHEN 'E2' THEN '22' WHEN 'E1' THEN '21' ELSE Grade.Grade END
This comes the result as down
Grade
_0_
_1_
_10_
_11_
_12_
_13_
_14_
_15_
_16_
_17_

_21_
_22_
_23_
_24_
_3_
_4_
_5_
_6_
_7_
_8_
_9_
Refresh
Now I want to convert this value to numeric and do some calculation
So I changed the formula as below
cast (CASE Grade.Grade WHEN 'E4' THEN '24' WHEN 'E3' THEN '23' WHEN 'E2' THEN '22' WHEN 'E1' THEN '21' ELSE Grade.Grade END as INT)
Now I get the following error

Dear Kart,
This give me another hint, Yes you are right. There was one row which returns neither blank nor any value.
I have done the code like following and it works fine
Thanks again for your support
Regards
Code: cast (CASE (CASE WHEN Length(Grade.Grade)=0 THEN '--' ELSE Grade.Grade END) WHEN 'E4' THEN '24' WHEN 'E3' THEN '23' WHEN 'E2' THEN '22' WHEN 'E1' THEN '21' when '--' then '-1' ELSE Grade.Grade END as Int)

I have a problem when using Google Maps, at some point my computer blanks the window and says there's a problem with display drivers, and it has recovered,but it doesn't. Problem doesn't happen with Int Explorrer, so I do not believe it is the computer

When using google maps through Firefox, after asking for a place which is not the general North America section which routinely comes up, the firefox screen goes white, with a narrow banner at the top. A message appears in the lower right corner which says something about display drivers having had a problem, but now have recovered. However the display doesn't recover and the banner message is that Firefox is not responding. When I go to restart Firefox if I go to the restore point, the page is still frozen out.
I do not believe it is a problem with my computer because it doesn't happen if I use I.E. to go to google maps, then G-maps works normally.
This phenomenon did not happen before the latest upgrade to either Google or Firefox. I have used Fiefox for a number of years and also Google Maps on previous computers and on this one, and not had this before.
This is a relatively young computer (Asus EeSlate 121) less than a year old. I have used Firefox since I bought it and until recently had no problem with Google Maps.

I solved it myself, after the "note" which came back from FF/Mozilla just as I finished my message, commenting on what it was that my system had , I wnnt back to check my plug-ins etc. I downloaded the latest Java, BOTH 32bit AND 64 bit versions and latest Firefox.
Now all is working.
Thanks,
B.

I had a problem with my WRT54GS not connecting to my inte...

I had a problem with my WRT54GS not connecting to my internet until I cloned my old routers mac address. I was using a BEFW11S4 which was bullet proof and worked for several years until I changed to Wireless G. Upon purchasing the WRT54GS and setting up all parameters exactly like I had before I could not make any connections, wireless or otherwise until I cloned my mac address to the same address as my previous router. Apparently my ISP had that mac address registered and would not properly perform DHCP even though all other paremeters were correct. I read lots of messages here on line with issues with the WRT54GS connecting and this fixed my problem outright. If you upgrade from a previous generation router (Linksys or otherwise apparently) copy your old routers mac address and clone it to your new router and you should be able to connect. This fixed my problem after several hours and days of troubleshooting. Good Luck Karnage

As an alternative to using MAC address cloning, you can phone your ISP, tell them you have a new router, and tell them to reset their system to accept the MAC address of your new router. This way, you won't have to remember the old MAC address, in the event that you need to reset your router to factory defaults.

Problem with threads running javaw

Hi,
Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
troy.

troy,
Try and post a minimum code sample of your app which
does not work.
When using javaw, make sure you redirect the standard
error and standard output streams to file.

Problem with setContentPane() in JFrame class

I recently discovered a problem with the setContentPane method in the JFrame class. When I use setContentPane(Container ..), the previously existing contentPane remains in the stack. I have tried nullifying getContentPane(), and all manner of things, but, each time I use setContentPane, I have another instance of a JPanel in the stack.
I'm using code similar to setContentPane(new CustomJPanel()); and each time the user changes screens, and a similar call to that is made, the old CustomJPanel instance remains in the stack. Can anyone suggest a way around this? On their own the panels do not take up very much memory, but after several hours of usage, they will build up.

I tried what you suggested; it only resulted in a huge performance decrease. The problem with memory allocation is still there.
Here is the method I use to switch screens in my app:
public static void changeScreen (JPanel panel){
          try{
               appFrame.setTitle("Wordinary : \""+getTitle()+"\"");
               appFrame.setContentPane(panel);
               appFrame.setSize(appFrame.getContentPane().getPreferredSize());
               appFrame.getContentPane().setBackground(backColour);
               for (int i = 0; i < appFrame.getContentPane().getComponents().length; i++)
                    appFrame.getContentPane().getComponents().setForeground(textColour);
               //System.out.println("Background colour set to "+backColour+" text colour set to "+textColour);
               appFrame.validate();
          catch (Exception e){
               //System.out.println("change");
               e.printStackTrace();
And it is called like this:
changeScreen(new AddWordPanel());The instantiation of the new instance is what is causing the memory problems, but I can't think of a way around it.

Problem with JFrame and busy/wait Cursor

Hi -- I'm trying to set a JFrame's cursor to be the busy cursor,
for the duration of some operation (usually just a few seconds).
I can get it to work in some situations, but not others.
Timing does seem to be an issue.
There are thousands of posts on the BugParade, but
in general Sun indicates this is not a bug. I just need
a work-around.
I've written a test program below to demonstrate the problem.
I have the problem on Solaris, running with both J2SE 1.3 and 1.4.
I have not tested on Windows yet.
When you run the following code, three JFrames will be opened,
each with the same 5 buttons. The first "F1" listens to its own
buttons, and works fine. The other two (F2 and F3) listen
to each other's buttons.
The "BUSY" button simply sets the cursor on its listener
to the busy cursor. The "DONE" button sets it to the
default cursor. These work fine.
The "SLEEP" button sets the cursor, sleeps for 3 seconds,
and sets it back. This does not work.
The "INVOKE LATER" button does the same thing,
except is uses invokeLater to sleep and set the
cursor back. This also does not work.
The "DELAY" button sleeps for 3 seconds (giving you
time to move the mouse into the other (listerner's)
window, and then it behaves just like the "SLEEP"
button. This works.
Any ideas would be appreciated, thanks.

I've had the same problems with cursors and repaints in a swing application, and I was thinking of if I could use invokeLater, but I never got that far with it.
I still believe you would need a thread for the time consuming task, and that invokeLater is something you only need to use in a thread different from the event thread.

Studio 12.1 Performace Analyzer 7.7 problem, with 'er_print' utility.

I am having a minor but nagging problem with a regression in the er_print utility of the Sun Performance Analyzer suite bundled in Studio 12. is there maybe a patch available or in the works?
I have not had any success in finding a resolution by searching the open literature
The issue is that the callers-callees listing only dumps functions in alphabetical order, ignoring the sort order specified by sort. This is a regression from the Performance Analyzer (7.4) behavior from Sun Studio 10. We only recently jumped to studio 12.1.
This functionality is documented here: http://docs.sun.com/app/docs/doc/821-0304/afaid?a=view (as well as many other references). To quote:
callers-callees
Print the callers-callees panel for each of the functions, in the order specified by the function sort metric (sort)."
I use a script input to er_print that in the past analyzed the top N functions sorted on inclusive thread time. Now I have to be sure to dump ALL functions and need a third-party search tool to find that information in the resulting report.
Has anyone heard of this problem or are there Performance Analyzer patch(es) available. I saw some for 7.6 and another for unspecified but have not seen this problem in patch notices.
Thanks.
Regards,
Steve

Nik, thanks for taking a look. We can't go to 12.2 because we're a software developer and we'll lose our binary compatibility with the release we've been building for the last few months. I'm a systems guy and will paste in a developer's example below.
Note Marc's url shows a 12.1 Performance Analyzer patch 142369-01 we have not yet installed. The patch notice description doesn't show much. I'll pass on patch info to remote user/developer.
Developer example:
I use a script input to er_print that in the past analyzed the top N functions sorted on inclusive thread time. Now I have to be sure to dump ALL functions and need a third-party search tool to find that information in the resulting report.
Heres a shortened (only 4) example of the behavior Im seeing the focus of the functions in callers-callees are NOT those of the functions determined by the sort metric.

IDES installation problem with DDIC password

Hello everybody,
After hours of searching and trying..
I have here a problem during a local installation of IDES ECC 6.0 on Windows Server 2008 with MAXDB. The installation stops in phase 27 of 29 u201Ccheck DDIC passwordu201D - test logon to SAP system failed, with the error message FRF-00007 "Unable to open RFC connection" in sapinst.
The MMC shows in the process list that the following processes stands oon "green": igswd, mag_Server and disp+work are running. The message of servers connection is OK, acts dialogue queue time is 0.00 sec.
I have already searched the forum, but I am not able to logon as user SAP* with u201C060. u2026u201D or as user DDIC with the password u201C199. u2026u201D to change the DDIC password to my password set during the installation (transaction -S000 / SU01). The login fails over the MMC as well as over the SAP GUI 7.10. I have tried this on the client 000, 001 and 800. The error message is u201CSAP Logon Failed - connection closed without message (CM_NO_DATA_RECEIVEDu201D). The SAP GUI gets down with "Work process restartet, session terminated".
What can help to solve the problem? Can it be a problem with the ms loop adaptor? Which static address IP must assign to the loop adaptor? Did i have to update the kernel of the data bank or is this not necessary? Can the information from dev_w help?
Can this link help me: BI 7.0 Installed but errored out during DDIC password check !!!!!!!
Thanks in advance
Lenvy

Good Morning everybody,
I started a next try, the mmc is running on green, the login starts up and......failed.
So the network setting seems to be correct.

The kernel is not patched. I just (try) to install the kernel files from the sap market place
IDES download destination. The install kernel file was: 51033508_7 - NW7 SR3 Kernel 7.00 for Windows / LNX X86_X64. I got an update / upgrade file, which is called: 51033508_8 - NW7 SR3 Kernel .... Upg ABAP.
Can anybody give me an adwise by reading those logfiles? Is the file ok for updating the kernel?
How do I upgrade the kernel by having no .exe - file? May the installation go on after patching the kernel?
Thanks you really much

Java API, problem with secondary keys using multi key creator

Hi,
I'm developing an application that inserts a few 100k or so records into a Queue DB, then access them using one of four Hash SecondaryDatabases. Three of these secondary dbs use a SecondaryMultiKeyCreator to generate the keys, and one uses a SecondaryKeyCreator. As a test, I'm trying to iterate through each secondary key. When trying to iterate through the keys of any of the secondary databases that use a SecondaryMultiKeyCreator, I have problems. I'm attempting to iterate through the keys by:
1: creating a StoredMap of the SecondaryDatabase
2: getting a StoredKeySet from said map
3: getting a StoredIterator on said StoredKeySet
4: iterate
The first call to StoredIterator.next() fails at my key binding (TupleBinding) because it is only receiving 2 bytes of data for the key, when it should be getting more, so an Exception is thrown. I suspected a problem with my SecondaryMultiKeyCreator, so I added some debug code to check the size of the DatabaseEntries it creates immediately before adding them to the results key Set. It checks out right. I also checked my key binding like so:
1: use binding to convert the key object to a DatabaseEntry
2: use binding to convert the created DatabaseEntry back to a key object
3: check to see if the old object contains the same data as the new one
Everything checked out ok.
What it boils down to is this: my key creator is adding DatabaseEntries of the correct size to the results set, but when the keys are being read back later on, my key binding is only receiving 2 bytes of data. For the one SecondaryDatabase that doesn't use a SecondaryMultiKeyCreator, but just a SecondaryKeyCreator, there are no issues and I am able to iterate through its secondary keys as expected.
EDIT: New discovery: if I only add ONE DatabaseEntry to the results set in my SecondaryMultiKeyCreator, I am able to iterate through the keys as I would like to.
Any ideas or suggestions?
Thank you for your attention,
-Justin

Hi Justin,
Sorry about the delayed response here. I have created a patch that resolves the problem.
If you apply the patch to your 4.6.21 source tree, and then rebuild Berkeley DB, the improper behavior should be resolved.
Regards,
Alex

Problems with inserting elements into vectors

Hi,
I have a problem with the setElementAt() method for vectors.
I want to initialise a vector that is same size as a previous vector declared in my program and insert float 0.0 in all the positions.
The code below is a for loop to do just this where count is the size of the previous vector.
for(int i=0;i<count; i++)
vLargest.setElementAt(zero,i);
}i have declared zero as a float
float zero = 0.0f;
the error that i'm getting is that it that the vector cannot be applied to a float.
Can anybody tell me what i'm doing wrong?
Thanks

Yes you need to store Objects in your Vector not primitives.
float is not an Object it is a primitive. But Float is an object.

Problem with ArrayList

Hello,
I am having a problem with a program I am trying to write. The idea of the program is to:
A) read a list of movies list from a text file
B) create an object for each movie using the information from the text file
C) place the objects into an arrayList
My problem is that when I check my arrayList it seems to only contain multiple copies of the first movie read from the text file. Here is my code
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.FileOutputStream;
import java.io.FileNotFoundException;
import java.util.ArrayList;
public class MovieReader
     PrintWriter outputStream = null;
     public void readFile()
          try
                  BufferedReader in = new BufferedReader(new FileReader("movie.txt"));
                  String str;
                  while ((str = in.readLine()) != null)
                       process(str);
                  in.close();
          catch (IOException e)
              e.printStackTrace();
     ArrayList <ValidMovie> movieList = new ArrayList<ValidMovie>();
     private void process(String line)
          String[] array = line.split("\t");
          int i = 0;
          for ( i = 0; i < array.length; i++)
               String tempTitle = array[0];
               String tempYear = array [1];
               String tempRating = array [2];
               String tempFormat = array [3];
               ValidMovie uuj = new ValidMovie(tempTitle, tempYear, tempRating, tempFormat);
               movieList.add(uuj);
          System.out.println("item at index 1 is:   " + movieList.get(1));
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     private void writeFile(String [] arrayL)
          String [] arrayWrite = arrayL;
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
//$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
     public static void main(String[] args)
          MovieReader mv = new MovieReader();
          mv.readFile();
//$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
}This is the code that creates an object for each movie:
import java.io.Serializable;
public class ValidMovie implements Serializable
     private String title;
     private String year;
     private String rating;
     private String format;
     public ValidMovie()
     public ValidMovie(String tTitle, String tYear, String tRating, String tFormat)
          title = tTitle;
          year = tYear;
          rating = tRating;
          format = tFormat;
     //Getters for title, year, rating and format
     public String getTitle ()
          return title;
     public String getYear ()
          return year;
     public String getRating ()
          return rating;
     public String getFormat ()
          return format;
     public String toString ()
          return title + "\t" + year + "\t" + rating + "\t" + format;
}The following is what I have in the movie.txt file:
Bamboozled     2000     2     DVD
What Lies Beneath     2000     1.5     DVD
Beneath the Planet of the Apes     1970     1     DVD
You Can Count On Me     2000     3.5     Theater
And finally this is the result when I run the code:
item at index 1 is: Bamboozled     2000     2     DVD
item at index 1 is: Bamboozled     2000     2     DVD
item at index 1 is: Bamboozled     2000     2     DVD
item at index 1 is: Bamboozled     2000     2     DVD
I am sure that it is something simple that I am overlooking but I cannot figure it out. When I change the index in the code:
System.out.println("item at index 1 is:   " + movieList.get(1));to 0 or 2 or 3 then result is the same, it will just show the first movie in the text file. Any help would be greatly appreciated. Thanks

Thanks for the reply, it helped but I am now getting 4 of each of the movies after adding you suggestion. This is much better now I just need to figure out why the loop is causing the extra copies. Thanks again :)
