Hi Joseph
We are using Forte 3.0 M2 on Solaris 5.8 The problem is with the push
buttons, After we grid the controls and they look intact in the NT
environment, but when we open the same window in SOlaris the controls are
far apart.Do you have any idea about this?
Regards
Vasundhara

Hello vashundara,
please say which Version of Forte and which kind/version your UNIX OS is.
There are some problems on AIX V4.3.x (Motif 2.x) and older releasese of
Forte (up to Forte 3.M.x) and so on and it is necessary to look what it is.
Maybe it is possible for you to say which widgets are the problem.
Thanks forward

Hi
We are facing a strange problem when we try to port our application from NT
to UNIX. The problem is that the GUI doesnt come properly. As per my
knowledge gridding all the controls on the GUI shouldnot create this
problem, but inspite of this we are facing it. Did anyone comeacross this
situation?
Thanks in advance

Problem with unix "foreach" command
Hi,
I am facing a problem with unix command "foreach". I trying to process files using unix foreach command. When running the script with 500 or 1000 files. It is running fine. But when I am trying to the script with 2000+ files. Its throwing an error "Arguments too long".
below is the syntax I am using in the script:
foreach name (*)
end
Could anybody help me on this issue.
Thanks in Advance.
Manasa.UNIX/Linux systems expand wildcards onto the command line before invoking the
individual commands. In effect, the shell rewrites the command line you give
substituting the wildcard expansion. There is a limit to how long this command
line can get.
For example, suppose you have two files ("foo" and "bar") in your directory.
The line:
foreach name (*)
echo $name
endgets rewritten to:
foreach name (foo bar)
echo $name
endand then the shell starts interpreting your script. So if you have many, many
files, the rewritten line becomes:
foreach name (f1 f2 f3 ... f10927)
echo $name
endso chances are the "foreach" line simply gets too long. To avoid problems do
it this way; it avoids any problems based on how many files you have:
ls | while read name
do
echo $name
doneThis way the shell never exceeds its line length limitations because the
wildcard is never expanded.

Hi everyone,
I have been trying to get this GUI built from the ground up and I have encountered a problem with the GridBag(exception error that the fields being added can not be done. Also, my method main seems to be off track, I have a working program which the display fields have been modified to display object and everything else is the same except that I can not get the GUI to run.
The following is the code and any suggestions as to what I can do to get this going will be appreciated. Thank you.

/*Beginning of the class type Inventory*/Hi Bryan,
I took your advice and decided to take a different approach to the problem I am having, I decided to stay somewhat with the basics with little knowledge I have about coding. I am new to this and I am trying to learn through the fire but it's getting hot so if you don't mind, can you tell me what I need to do to fix the error messages I am getting.
1. "else" without "if',
2. can't load my icon-a JPG
3. exception in thread amin
process complete.
4.Text area for displaying an iteration of the input
the code is not as long as the other one! any help will be appreciated. Also I am attaching the code to the GUI that does work but I can not seem to get the actionListener aspect to work. Thanks again.
//this one works and it serves as a model for what I am //trying to do in the fields. as well as designate a text area //where a each entry per iteration of input is displayed

Problem with Unix version of Reports
When I run the report(filenam.rep) off of
my P.C., it works fine. Then when I transfer
it over to Unix and run the report, I get
some of the values in my report copied into
places they don't belong. For instance,
I have a value for the last row and last column in my report that gets copied to the
first value in the last column of every page
except for the first page. The proper value
doesn't appear and it gets replaced by this
value instead. I am running Reports 2.5 on
both my P.C. as well as Unix. My P.C. is
an NT 4.0 workstation. My command line on Unix looks like this:
r25runm report=${report} userid=reitprod/namrem batch=YES paramform=NO \
buffers=1000 destype=file desname=${TEMP}.lis \
${PARAMETER_STRING}
I also have Designer 6.0 installed on my P.C.
I recently installed a patch to fix a problem
with formatting in Reports 6.0. I am wondering whether the patch might have something to do with incompatibility between
Reports 2.5 on my P.C. and Reports 2.5 on
the Unix system.
nullHello,
We need more information in order to help. How are you requesting the report (command line, URL, ?). What file is it asking for?
Regards,
The Oracle Reports Team --skw

Need help!!!! GUI problems with netbeans
i have a problem with the interface i created using netbeans.
i created a JFrame, inside it a JDesktopPane, and inside that 3 JInternalFrames. the problem is in one of the JinternalFrames, i have 4 radio buttons which i forgot to add to a buttongroup and whenever i try to do that, the GUI doesn't work anymore. The bigger problem is that if i undo the changes, the thing still doesn't work and i have to copy my backup project folder over the one i work on to get an output.
i tried to edit the source code to add the 4 buttons to a button group but netbeans won't let me since i created the buttons thru it not by writing it myself
please i really need help with this and i hope its a stupid thing i'm just overlooking.
If u need the code, i will gladly post it.
thanks in advanceif you're not using a netbeans-specific layout manager, copy the working code
into notepad, make the changes, then compile and run from the command prompt.
if all works OK, dump netbeans -
Suddenly I am experiencing problems with iCal crashing after I try to drag items into the TO DO column. The calender grid suddenly shows through the TO DO area and everything comes to a halt. Any suggestions.
Dual 450 G4 Mac OS X (10.4.8)When I try to do anything involving the "to do"'s things just stop working. Here is where it gets strange. If I transfer via iSync a "to do" from my palm pilot to iCal the "to do" will not show up in iCal. BUT then when I sync Omni Outliner with iCal it will pull the "to do" from somewhere in iCal and put it in the "in box" in Omni Outliner. What in the heck is going on here?

URGENT!! problems with Unix command, please help
I am trying to use the following Unix command and I keep getting error messaages from stdError. However if I run the same command from the command line it works perfectly. For some reason when I run the command from inside the program it thinks the append symbol ">>" is another file.
String command = " cat /users/02/wjoc1/Test/list.mod >> /users/02/wjoc1/Test/Blacklist ";
Process p = Runtime.getRuntime().exec(command);
The error get is :
/bin/cat: >>: No such file or directory
Any help would be greatly appreciatedThe better solution for this problem is write a shell script for the action you wnat to perform and execute it using the runtime.exec().In your case just cut and paste cat /users/02/wjoc1/Test/list.mod >> /users/02/wjoc1/Test/Blacklist in to a file and save it. use that file as a argument for the exec method it will work.
cheers

GUI problem with textfields, reading in text from a textpad
Alright well, here is my problem. I am having trouble with aliging the textfields to how I want it but I can't get it to come out how I want it. First, I am trying to figure out how to have the some text appear right above a textfield. Example:
File Name
I can't get it appear that way, the text appears side to side with the textfield. And the other problem is how can I made the size of textfield to how I want it. I was reading that you have to assign a specfic number in the text field.
This is the code I have so far:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class IP_Header extends JApplet
private JTextField lookUp, showInfo;
private JButton analyze;
private JLabel msg;
public void init()
JPanel p1 = new JPanel();
p1.setLayout(new GridLayout(3,2));
p1.add(new JLabel("File Name"));
p1.add(lookUp = new JTextField());
p1.add(analyze = new JButton("Analyze"));
p1.add(showInfo = new JTextField());
msg = new JLabel(" ");
Container cp = getContentPane();
cp.setLayout(new BorderLayout());
cp.add(p1, BorderLayout.NORTH);
With this what I am tryin to do is as follows:
File Name
* "TextField" * *
**************** * This is a textfield where I am just going to
* have some text appear in it
* "Button" * *
Thank you for your help. I hope you can help me. I haven't done java for a quite a while. Thanks againThanks for help ... really helpful and understanding. I am trying to read a file from the computer which has some numbers in it and I want those numbers to be shown on the textfields individually. The numbers are in a notepad file and they are .... 4, 5, 200, 780, 1, 0, 0, 12, 6, 0, 129, 24, 21, 44, 133, 62, 159, 7. I got the program to compile and everything by adding the code that I believe should work . But whenever I put the file name in and press the button analyze ... it gives me a error saying "Exception: access denied (java.io.FilePermission c:\TCP read) .. can't quite get it ...here the code:

[SOLVED] Problem with UNIX permissions
Hello everyone.
It seems I don't have the permission to write in a folder but I don't understand why :
olivier:~$ ls -l /srv/
total 8
dr-xr-xr-x 2 root ftp 4096 Feb 14 10:16 ftp
drwxrwxr-x 2 http http 4096 Feb 22 16:53 http
olivier:~$ cat /etc/group | grep http
http::33:olivier
olivier:~$ cd /srv/http
olivier:/srv/http$ touch myfile
touch: cannot touch `myfile': Permission denied
So /srv/http is owned by user http of group http, with write permission for group members.
I am part of the http group but I can't create (or delete) a file in /srv/http.
Is this behaviour normal?
Thanks!

I guess that was the problem since now after rebooting it works!

Problem With UNIX command in ODI Environment.
A procedure is used in our package which involves moving a file from a folder to another in a UNIX server.
The procedure uses an OS command - 'os.system' to execute unix command.
The unix command is a grep command which seems to work fine when executed alone.
But when this procedure is executed ,it fails.
The following code raises an error and the procedure fails.:

The unix command is a grep command which seems to work fine when executed alone. :-
I guess you executed this from your Unix server , so it work fines.
And when you are trying to execute outside from this (using ODI) , its failing , right ?
Can you please check the permission settings for that script file (sh).
Please try by giveing the full permission (specifically execution permission) for all users connecting from other machines.
This can be one of the reason for the failure .
please let me know if this is not working

Problem with Adobe Reader Plug-In (7, 8, and 9) on Windows XP
We are experiencing a problem with the Adobe Reader plug-in and viewing documents hosted at our site. The problem seems to happen with larger (over 5 MB) PDF files enabled for fast web viewing. The problem never happens when viewing PDF image only files which are not enabled for fast web viewing. The problem happens inside and outside our firewall, so it is not a firewall problem. My organization has been hosting PDF files to the web at least all this decade, and this is the first time we have experienced and documented this problem on this scale. We have ruled out the program creating the PDF file is causing the problem as I have eight sample PDF files created and modified by a variety of programs exhibiting the same issue.

I can reproduce the problem with Internet Explorer 8.0.6 and Firefox 3.5.4 using Adobe Acrobat Plug-In 7.0.9.50 running on Windows XP Professional SP3. Others have reproduced the problem with 8 and 9 versions of the plug-in on Windows XP Professional and Home. Oddly, no one has been able to reproduce the problem with Unix/Linux versions of the plug-in or third party plug-ins. This points to it being something wrong with Adobe Reader.
The problem is when I attempt to view one of the eight PDFs in my browser, I can severely stall or lock it up if I attempt to view more than the first page before the whole document downloads. Sometimes if you wait it out, the browser will unlock, but not display text on the pages. Sometimes if you wait for the whole document to load before switching pages, it works. Sometimes you can start switching pages and the document will not lock up at all. All eight documents can be viewed without issue if downloaded to the PC's hard drive and then viewed with Adobe Acrobat 7.0.
Can anyone point me to a technical document or reason why we would be experiencing this issue? Even better, does anyone know the solution to these issues?
Any help will be much appreciated.I looked at a few documents. They appear to be scans and scans that have been OCRd. It is also likely they have not been optimized for page view. This means that the document has to be fully downloaded before viewed. That means the browser may appear to freeze until the entire document is downloaded. Downloading the entire document appears to be a reasonable way to handle these files.

Design Problem with GUI sub vi
Hello community,
in general, I would like to separate the GUI from the data, but I get
a problem with this design approach in LabView:
I often have sub VIs that are supposed to control something.
Therefore, these VIs consist of a control loop. A GUI window should
show the regulation process (showing how the tracking error is
hopefully approaching zero etc.). As I said, this GUI should be a
separate VI (separate from the control loop VI). Since the GUI has to
be updated on each sample, it is clear that the GUI VI should be
inside the control loop, and therefore, it should be a sub VI of the
control loop VI.
Now, the problem is that the control loop VI itsself is a sub VI
because the whole regulation is just a subsystem of the whole program
(The main VI doesn't have a GUI, but first starts a (GUI) input mask
for the same reason: separate the GUI from the rest).
But back to the GUI VI inside the control loop. I must check the 'Show
Front Panel When Called' option. But I can't check the 'Close
Afterwards if Originally Closed' option since the GUI VI would appear
and disappear in the control loop - according to the loop's sample
rate. However, if I don't check the 'Close Afterwards if Originally
Closed' option then the GUI VI will continue to show, even after the
control process is finished.
So in other words: I need the possiblity to close the GUI VI
programatically, after the control process is finished.
Any ideas?

thanks for your answer

I try to avoid globals. Now, suppose I had multiple unrelated control
loops. I had to suppose a global variable for each of these
subsystems. I already use globals for the GPIB device IDs. I wouldn't
like more.

But if I split the GUI: How can I view them simultaneously? The user
must see input and output simultaneously, in one window.

Your approach sounds interesting. Is there a sample for this
architecture in the examples?
Anyway, I have to point out that I have several unrelated GUI windows
in my application. There is no notion of a main GUI in my application.
The control loop is just one feature of my application, so it doesn't
make sense to use the control GUI as the top-level VI. At application
startup a user input form is displayed (it also has some sort of menu
selection). But even this window can't be toplevel since it provides
an Option radio button (that shows and hides controls, accordingly) a
CONTINUE button, and a STOP button which implies that the input
form.vi must be
in a loop.
The problem is that I can't send messages to windows in LabView as I
am used to in Win32/VC++.

}Thanks for the answer. I take a look at Swing Worker but i have a few problems :
1)The GUI doesn't freeze but nothing happens either.
2) When i remove the sendMessage method and i put only a System.out.println(somethingToPrint); it works but only once. After i hit second time my send button nothing happens. Somewhere i read that works only once is that true or i misunderstood? And if yes how i can do it every time i press the send button?
Could you take a look at my code?
