Working with forms, buttons and text files

please am new to java am working on the project. please see sample below, can anyone tell me how i can get the button in form1 to open form2 and also how the information entered in the textfield can be written to a text file. THANKS
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Form1 extends JFrame
     static JFrame frame;
     static JPanel panel;
JLabel label;
     JTextField text;
     JButton btn;
     GridBagLayout g;
GridBagConstraints gbc;
     public Form1()
          label = new JLabel ("Label");
          gbc.gridx = 0;
gbc.gridy = 1;
g.setConstraints(label, gbc);
panel.add(label);
          text = new JTextField();
gbc.gridx= 1;
gbc.gridy = 1;
g.setConstraints(text, gbc);
panel.add(text);
          btn = new JButton ("CONTINUE");
          gbc.gridx = 0;

g.setConstraints(text2, gbc);
panel.add(text2);
}

please am new to java am working on the project.
please see sample below, can anyone tell me how i can
get the button in form1 to open form2 For opening form2 from form1 you can add a actionListener to the button.When the button is pressed instantiate the other class and render it visible which i leave it to you to implement.
and also how
the information entered in the textfield can be
written to a text file. THANKSUse getText ( ) method of JTextField to retrieve the text from it and then it's ordinary file io operations for which i guide you to the tutorials here

Working with multiplie Panels And C Files

Hi !
I have a general question...
I'm workign with CVI 9.1 , and i have serveral C files .
At the main.c file I'm loading all my panels for ex Panel Name - PREF, Panel Handle - panelPrefHandle
At the service.c file I'm trying to use GetCtrlVal(panelPrefHandle,....,...);
OR GetCtrlVal(PREF,....,...);
At service.c i'm including #include "main.h"
Still I'm getting the error :
NON-FATAL RUN-TIME ERROR: "Service.c", line 677, col 29, thread id 0x00000D30: Library function error (return value == -42 [0xffffffd6]). The handle is not a panel handle
so my question is how can i pass panel handel over serveral c files ?

Hi,
you need to include the include file of the panel: if you build and save a panel in the UIR editor, a corresponding *.h file is generated; you need to include this file in the *.c file which will access this panel, because the panel name etc. are defined in the panels' include file.

Basically you would need Acrobat. However, it is now also possible to create basic form fields using just the free Reader. In fact, I've been working on a tool that allows you to do it, so if you're interested in it please contact me privately.

Hi Paul ,
It could be a compatibility issue as well as Acrobat 8 is an older version.
Do you get any error message while registering for the product?
Try repairing it and once and also check for updates as well.
Is it happening with all the word files or any specific one'?

Buttons and text items on oracle forms 6i

can i create dynamic buttons and text fields on oracle forms 6i.
i mean when i insert record in database then automatically creat a button on form.
Regards
Munawer hussain

Hi,
One physical button is enough for a series of "functional buttons" per amount of simultanious visisble buttons. You can change the button prompt at run-time depending on a certain condition. That same condition can also be used when executing the when-button-pressed (wbp) trigger.
Example:
suppose you have 2 functions that you want to create buttons for: enter query and execute query. Only 1 button is visible at one time. In design time you create 1 button. In run-time, depending on :system.mode you set the button prompt to "enter query"or "execute query" and in the wbp trigger you write
begin
if :system.mode = 'QUERY'
then
execute_query;
else
enter_query;
end if;
end;
Kind regards

Can I share files from other programs or just Adobe apps files. I work with Final Cut and Premiere X

Can I share files from other programs or just Adobe apps files. I work with Final Cut and Premiere X.? Need to share files up to 6GB.
I need to know if the 20 gb limit is about all that I share, or if it's just about whatis in the clouds. If I take, recover my limit?
The speed of upload e download is good?

The Creative Cloud file storage could be used for video assets but speed and performance might vary based on location. I would suggest you testing it out yourself using your Adobe ID before subscribing. Performance would not change after you joined.

Since downloading Yosmite on my MAC I have not been able to download photos to LR 5. Error message: "the following files were not imported because they could not be read (335).I have been working with several forums and have dtried going into preference

LR 5 - using it on a MAC-
Error message: "the following files were not imported because they could not be read (335).
I have been working with several forums and have tried all recommendations and none have worked.
I have tried reloading new LR 5 - and it worked for a short time and then stopped.
Very frustrated that I cannot talk with someone at Adobe.
The folks that have made recommendations are great but once their suggestions dont work they drop the link,
Is there someone or someplace I can take my computer to fix this issue.
It seems to be a problem between LR and Yosemite.

The permissions have been changed on the destination folder where the photos are to be copied into.
You must make sure that the permissions are set to Read and Write.
Or perhaps the destination folder has been changed accidentally to something else, and you need to change it back to whatever it used to be.

ok. I hope someone can answer my question. I am new to photoshop. I need version cs4 in order to work with a designer and printer on some logo work. I've tried to download it but it just gives me individual files with no installer and nothing - including the adobe "instructions" seems to work. How can i get this software in a downloadable format? is it actually free - I'm assuming it is... Hope someone knows the answer to these questions...

The download itself is free and is valid for 30 days only. After that, the software ceases to work.
CS4 is pretty old, no longer sold and no longer supported by Adobe. It's also not compatible with many modern OSes.
Why do you have to work with such an obsolete version of Photoshop?
What kind of "designer" uses it?

I was online earlier this week and liked the forms with submit buttons and the Adobe site directed me to upgrade to Adobe PRO XI in order to use forms so I bought five licenses. Just had it installed today and it is now asking me to sign up for forms Central in order to use this feature. What gives? The Adobe site gave me the impression that I would have this feature after purchasing the new upgrade. I would not have purchased the upgrade, let alone five of them had I know this. Am I missing something?

Acrobat XI comes with the Fromscentral AIR application and the ability to create PDF forms authored in Formscentral. To have more than the free (1 form with 50 responses) level account you need to sign up for a Formscentral subscription.

Populating a form from a text file

I have an Oracle form which schedules students into courses. The form collects the student id, name, school, and course code. A "RUN" button then does the scheduling. The form is not a table, meaning the data is not all stored together in an Oracle table. The user currently has to manually enter each piece of information before a student can be scheduled. I would like to be able to auto populate this form/screen with data from a text file. I cannot use SQL Loader since the data is not going into a table. Is there a way to take my text file and make it appear on the form/screen when the form opens? Then my user just has to click the RUN button in order to schedule the students instead of hand entering all the data.
Any help on this would be greatly appreciated!

hi
USING THE TEXT_IO PACKAGE
Abstract: This document describes the functionality of the TEXT_IO
package and explains how to use it to access the file
system effectively.
Keywords: TEXT_IO;FILE;IO;PACKAGE
Using the TEXT_IO Package
=========================
Oracle Procedure Builder, "an integrated, interactive environment for
PL/SQL", is shipped with several built-in packages which, if used
properly, can greatly boost development productivity. These built-in
packages are not installed as extensions to the STANDARD package;
hence, when you reference a construct from any of these packages, you
must prefix the package name to the construct.
TEXT_IO provides constructs that allow programmers to read information
from and write information to a file system. The procedures and
functions in TEXT_IO fall into the following three categories:
Category 1: File Operations
FILE_TYPE - Declares a file type variable as a handle to the file being
processed.
Syntax: TEXT_IO.FILE_TYPE;
FOPEN - Opens a file and returns a handle to the specified file of
type FILE_TYPE.
Syntax: TEXT_IO.FOPEN(file_specs VARCHAR2, file_mode VARCHAR2);
The file mode can be R(read), W(write) or A(append).
FCLOSE - Closes an open file.
Syntax: TEXT_IO.FCLOSE(file_specs VARCHAR2);
IS_OPEN - Checks if the specified file is currently open and returns a
boolean.
Syntax: TEXT_IO.IS_OPEN(file_type FILE_TYPE);
Category 2: Output Operations
PUT - Concatenates the supplied data to the current line of an open file.
Syntax: TEXT_IO.PUT(file FILE_TYPE, data DATA_TYPE)
Valid data types are VARCHAR2, DATE, NUMBER, PLS_INTEGER.
All data except VARCHAR2 is converted to a character string.
PUTF - Formats and writes a character string to an open file,
doing a C-like substitution.
Syntax: TEXT_IO.PUTF(file FILE_TYPE, format VARCHAR2,
arg1[,...,arg5] VARCHAR2);
Format is an optional parameter. If it is omitted, only
one argument value can be passed.
You can embed up to 5 "%s" patterns within the format string,
which can be replaced by the corresponding strings
(arg1 ... arg5) at execution.
PUT_LINE - Concatenates the given argument string to the file
followed by a newline character.
Syntax: TEXT_IO.PUT_LINE(file FILE_TYPE, data VARCHAR2);
NEW_LINE - Concatenates n number of newline characters to the current line,
where n is the second argument with a default value of 1.
Syntax: TEXT_IO.NEW_LINE(file FILE_TYPE, n PLS_INTEGER := 1);
Note: If the file name is not specified each of the above cases, the
output is directed to the Interpreter.
Category 3: Input Given Operations
GET_LINE - Reads a line from an open file into the parameter.
Syntax: TEXT_IO.GET_LINE(file FILE_TYPE, data_item OUT VARCHAR2);
Note: After a GET_LINE call, the file pointer moves to the next
line and subsequent lines are read in after each call. If the
line to be read exceeds the size of data_item, the VALUE_ERROR
exception is raised. If no more characters can be read from the
file, the NO_DATA_FOUND exception is raised. You cannot move this
pointer back to the previous line though this can be simulated
using your own buffer scheme.
If a file name is provided for any of the above routines, this file
must be accessible to Oracle Forms. In addition, you must provide the
complete path. If no path is given, Forms assumes the file is in the
current working directory and does not search for the file in the file
system. The accessibility is determined as follows:
On Windows, a TEXT_IO package function call only accesses local
drives. It does not recognize any Universal Naming Conventions like
\\machine_name\drive_letter. To access files on remote machines using
the TEXT_IO package, map a letter to the remote drive through the File
Manager.
On UNIX, the absolute path must be given for the location of the file.
Forms does not recognize relative paths provided for the file. This is also
the case for VMS and other platforms. When you do not specify a path, Forms
assumes the file is in the current working directory.
For more information, refer to the TEXT_IO Package section in the
"Oracle Procedure Builder Packages" chapter of the Oracle
Developer/2000 Procedure Builder Developer's Guide Manual.
Sample Form
The following sample form explains some of the concepts and the
syntax. The form reads in lines from a specified text file one at a
time and displays them in a text item. It enables the user to parse
the file by getting the next or the previous line. In addition, the
user can write any line currently displayed to a specified output
file.
Create a single non-base table block. Put the following items and
buttons on it. Create the appropriate boilerplate text for each item.
All items go on the same canvas. No database connection is required
for this application.
Create the following text items:
1. Name INPUT_FILE_SPECS
Item Type Text Item
Data Type Char
Maximum Length 30
2. Name LINE_READ
Item Type Text Item
Data Type Char
Maximum Length 300
3. Name OUTPUT_FILE_SPECS
Item Type Text Item
Data Type Char
Maximum Length 30
4. Name LINE_NO
Item Type Text Item
Data Type Number
Maximum Length 30
Create the following buttons and associated triggers:
1. Name OPEN_AND_READ_FROM_FILE
Label Echo file using TEXT_IO package
Associated Button Trigger:
Name WHEN-BUTTON-PRESSED
Trigger Text:
IF :input_file_specs IS NOT NULL THEN
:line_no := 1;
ECHO_TEXT_IO;
ELSE
MESSAGE('You must enter a valid input file name
with a complete path');
END IF;
2. Name NEXT
Label NEXT LINE
Associated Button Trigger:
Name WHEN-BUTTON-PRESSED
Trigger Text:
:line_no := :line_no + 1;
ECHO_TEXT_IO;
3. Name PREVIOUS
Label PREVIOUS LINE
Associated Button Trigger:
Name WHEN-BUTTON-PRESSED
Trigger Text:
IF :line_no = 1 THEN
MESSAGE('You are on the first line of the file.');
ELSE
:line_no := :line_no - 1;
TEXT_IO.FCLOSE(variable_declarations.infile);
/* Close the file then reopen it with the
ECHO_TEXT_IO package. This resets the
file pointer. */
ECHO_TEXT_IO;
END IF;
4. Name WRITE_LINE_TO_FILE
Label WRITE CURRENT LINE TO Output FILE
Associated button trigger:
Name WHEN-BUTTON-PRESSED
Trigger Text:
IF :output_file_specs IS NOT NULL THEN
write_to_file;
ELSE
MESSAGE('Must enter a valid output file name with
complete path');
END IF;
Create the following program units and package specifications:
1. ECHO_TEXT_IO* (Procedure Body)
PROCEDURE echo_text_io IS
-- infile TEXT_IO.FILE_TYPE; /* Not used in this program */
linebuf VARCHAR2(300);
line_counter INTEGER;
BEGIN
line_counter := 0;
Note that the IF condition would be redundant if you use
a local variable (commented out above) to save the file pointer.
Infile is a local variable, so the binding would be lost each
time you exited the program. The use of package variables
to act as global file type handles resolves this problem.
IF TEXT_IO.IS_OPEN(variable_declarations.infile) THEN
If the file is open, read in the next line.
TEXT_IO.GET_LINE(variable_declarations.infile, linebuf);
line_counter := line_counter + 1;
ELSE
The file is closed for the application when you display the
previous line; see the WHEN_BUTTON_PRESSED trigger on the
PREVIOUS item. Since the file pointer cannot move
backwards, you must reset the file pointer and loop to the
specified line.
variable_declarations.infile := TEXT_IO.FOPEN(:INPUT_FILE_SPECS, 'r')
-- variable_declarations.infile := TEXT_IO.FOPEN('c:\autoexec.bat', 'r')
/* You can also hard-code the value */
WHILE line_counter < :line_no LOOP
TEXT_IO.GET_LINE(variable_declarations.infile, linebuf);
line_counter := line_counter + 1;
END LOOP;
END IF;
:line_read := linebuf;
EXCEPTION
WHEN NO_DATA_FOUND THEN
MESSAGE('End Of File reached.');
:line_no := :line_no - 1;
WHEN OTHERS THEN
MESSAGE('UNHANDLED EXCEPTION RAISED in ECHO_TEXT_IO
procedure - Check the file name');
MESSAGE('U. E. R.');
END;
2. VARIABLE_DECLARATIONS (Package Spec)
PACKAGE variable_declarations IS
The following declarations are public and, hence, visible
to the Forms application.
infile TEXT_IO.FILE_TYPE;
outfile TEXT_IO.FILE_TYPE;
line_number NUMBER;
END;
3. WRITE_TO_FILE* (Procedure Body)
PROCEDURE write_to_file IS
BEGIN
IF NOT TEXT_IO.IS_OPEN(variable_declarations.outfile) THEN
variable_declarations.outfile := TEXT_IO.FOPEN(:OUTPUT_FILE_SPECS, 'a');
END IF;
TEXT_IO.PUT_LINE(variable_declarations.outfile, :line_read);
END;Sarah

Saving report as PDF and text file

Currently, I saved my report as PDF. It opens in Acrobat reader automatically when the report is executed. Is there a way for me to save it as PDF and as a text file at the same time? (without having to open the file in Acrobat reader and saving it)

You can add your PDF and TEXT file formats to a distribution list (Instead of GENERATE REPORT TO A FILE). To do this:
1. Go to your Object Navigator and highlight your report.
2. Right click on your report. Select Property Palette.
3. Select Distribution
4. You can add of of the formats that you want to print or save to the report to.
5. You will have to add Distribution Id (any number starting with 1) where you want the file to be saved (c:\my_reports\inventory.pdf), the type of file: PDF and how many copies you want: 2
6. Click OK after finishing...
To make it work ... You would highlight your report from your Object Navigator and then choose FILE-DISTRIBUTE and this will save it to all the files your specified and/or printer.
