How to create and handle a text file in CVI
Is there any way to create and handle (like...open,write,read,truncate,close) the .txt file in CVI?
Sure. CVI is a regular C compiler and hence you can use all ANSI C functions. In addition you can use the File I/O functions from the utility library.

How to create a tab-delimited text file?
Hi,
I need to create a tab-delimited text file at presentation server getting content from an internal table. My file should also have a header - also tab-delimited. Data for a header is stored in some work area.
Any ideas how to add tab-delimiter into a text file? Or should I go for a HEX file and use
CONSTANTS: c_tab TYPE x VALUE '09'.
and separate my data with this constant instead?
Any thoughts whould be appreciated.
TIA

How to create and edit a .ini file using java
Hi All...
Pls help me in creating and editing an .ini file using java...
thanks in advance
Regards,
sathyaLet's assume the ini file is a mapping type storage (key=value) so lets use Properties object. (works with java 1.4 & up)
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Properties;
public class Test {
private static Properties props;
public static void main(String[] args) throws IOException {
File file = new File("test.ini");//This is out ini file
props = new Properties();//Create the properties object
read(file);//Read the ini file
//Once we've populated the Properties object. set/add a property using the setProperty() method.
props.setProperty("testing", "value");
write(file);//Write to ini file
public static void read(File file) throws IOException {
FileInputStream fis = new FileInputStream(file);//Create a FileInputStream
props.load(fis);//load the ini to the Properties file
fis.close();//close
public static void write(File file) throws IOException {
FileOutputStream fos = new FileOutputStream(file);//Create a FileOutputStream
props.store(fos, "");//write the Properties object values to our ini file

How do I create and display a text file?
Hello friends,
I am trying to create a simple unix like operating system with very basic functionality. I have a hard time trying to create a "mktext" file and actually display the contents of the text file with the "cat" command. For example:
// If I type
$$ mktext test.txt "We are one"
$$ Text file is created
// And if I type
$$ cat test.txt
// This line will appear
$$ "We are one" // Only the contents of the test.txt will display.
That is what I want to do, but currently stuck. I would appreciate any help and suggestions. Thanks...This will do it:
import java.io.*;
import java.util.*;
public class Osys
BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in));
public Osys()
try
while(true)
System.out.print("$$ ");
String s = keyboard.readLine();
analize(s);
catch(Exception e){}
private void analize(String s)
if (s.trim().equals("")) return;
StringTokenizer st = new StringTokenizer(s," ");
if (!st.hasMoreTokens()) return;
String s1 = st.nextToken();
if (s1.equals("cat"))
if (st.hasMoreTokens()) readIt(st.nextToken().trim());
System.out.println("");
return;
if (s1.equals("mktext"))
if (st.hasMoreTokens()) writeIt(st.nextToken().trim(),s);
System.out.println("");
return;
// write
private void writeIt(String file, String line)
BufferedWriter writer;
StringTokenizer st = new StringTokenizer(line,"\"");
if (st.countTokens() != 2) return;
st.nextToken();
try
writer = new BufferedWriter(new FileWriter(file));
writer.write(st.nextToken());
writer.close();
System.out.println("$$ Text file is created");

How to create spaces in a text file
Hi forum
i am creating a text file with the GUI_DOWNLOAD function, my problem is that i need to create some lines with spaces at the end of the line. But i can´t, i had concatenate spaces and i have created structures but in the file doesn´t appear that spaces to the end of the line. example
- line
abcdefghij
- i need
abcdefghij******************
= space
tghnks
JosueThnks Pawan, the correct code to append spaces to the end of line for save in a file is, this is an example:
<b>DATA: space_character type c.</b>
DATA: s_var1 type c(10).
* Init the space character
<b>space_character = cl_abap_char_utilities=>minchar .</b>
s_var1 = '123'.
* we need seven spaces more to complete the length of s_var1, then :
* We need to concatenate into field
DO 7 TIMES.
<b>CONCATENATE s_var1 space_character INTO s_var1.</b>
ENDDO.
* Move to the internal table for save the text in a file
MOVE s_var1 TO t_out-line.
APPEND t_out.
* Finally we call the GUI_DOWNLOAD function
CALL FUNCTION 'GUI_DOWNLOAD'
EXPORTING
filename = fullpath
filetype = 'ASC'
TABLES
data_tab = t_out
EXCEPTIONS
file_write_error = 1
no_batch = 2
gui_refuse_filetransfer = 3
invalid_type = 4
no_authority = 5
unknown_error = 6
IF sy-subrc <> 0.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
And it´s all... looks easy but many partner doesn`t know

How to create and use library JAR files with command-line tools?
Development Tools -> General Questions:
I am trying to figure out how to put utility classes into JAR files and then compile and run applications against those JAR files using the command-line javac, jar, and java tools. I am using jdk1.7.0_17 on Debian GNU/Linux 6.0.7.
I have posted a simple example with one utility class, one console application class, and a Makefile:
http://holgerdanske.com/users/dpchrist/java/examples/jar-20130520-2134.tar.gz
Here is a console session:
2013-05-20 21:39:01 dpchrist@desktop ~/sandbox/java/jar
$ cat src/com/example/util/Hello.java
package com.example.util;
public class Hello {
public static void hello(String arg) {
System.out.println("hello, " + arg);
2013-05-20 21:39:12 dpchrist@desktop ~/sandbox/java/jar
$ cat src/com/example/hello/HelloConsole.java
package com.example.hello;
import static com.example.util.Hello.hello;
public class HelloConsole {
public static void main(String [] args) {
hello("world!");
2013-05-20 21:39:21 dpchrist@desktop ~/sandbox/java/jar
$ make
rm -f hello
find . -name '*.class' -delete
javac src/com/example/util/Hello.java
javac -cp src src/com/example/hello/HelloConsole.java
echo "java -cp src com.example.hello.HelloConsole" > hello
chmod +x hello
2013-05-20 21:39:28 dpchrist@desktop ~/sandbox/java/jar
$ ./hello
hello, world!I believe I am looking for:
1. Command-line invocation of "jar" to put the utility class bytecode file (Hello.class) into a JAR?
2. Command-line invocation of "javac" to compile the application (HelloConsole.java) against the JAR file?
3. Command-line invocation of "java" to run the application (HelloConsole.class) against the JAR file?
I already know how t compile the utility class file.
Any suggestions?
TIA,
DavidI finally figured it out:
1. All name spaces must match -- identifiers, packages, file system, JAR contents, etc..
2. Tools must be invoked from specific working directories with specific option arguments, all according to the project name space.
My key discovery was that if the code says
import com.example.util.Hello;then the JAR must contain
com/example/util/Hello.classand I must invoke the compiler and interpreter with an -classpath argument that is the full path to the JAR file
-classpath ext/com/example/util.jarThe code is here:
http://holgerdanske.com/users/dpchrist/java/examples/jar-20130525-1301.tar.gz
Here is a console session that demonstrates building and running the code two ways:
1. Compiling the utility class into bytecode, compiling the application class against the utility bytecode, and running the application bytecode against the utility bytecode.
2. Putting the (previously compiled) utility bytecode into a JAR and running the application bytecode against the JAR. (Note that recompiling the application against the JAR was unnecessary.)
(If you don't know Make, understand that the working directory is reset to the initial working directory prior to each and every command issued by Make):
2013-05-25 14:02:47 dpchrist@desktop ~/sandbox/java/jar
$ cat apps/com/example/hello/Console.java
package com.example.hello;
import com.example.util.Hello;
public class Console {
public static void main(String [] args) {
Hello.hello("world!");
2013-05-25 14:02:55 dpchrist@desktop ~/sandbox/java/jar
$ cat libs/com/example/util/Hello.java
package com.example.util;
public class Hello {
public static void hello(String arg) {
System.out.println("hello, " + arg);
2013-05-25 14:03:03 dpchrist@desktop ~/sandbox/java/jar
$ make
rm -rf bin ext obj
mkdir obj
cd libs; javac -d ../obj com/example/util/Hello.java
mkdir bin
cd apps; javac -d ../bin -cp ../obj com/example/hello/Console.java
cd bin; java -cp .:../obj com.example.hello.Console

How to create and handle sharepoint custom list with more than 300 columns?
Hi,
I have requirement for our project where in the input form is having around 320 columns in it.below are the columns and data types.
Single line of text-180
Yes or No Radio button -95
Date time control-35
Checkbox-10
I have checked the sharepoint boundry and limits for columns and data types.
https://technet.microsoft.com/en-us/library/cc262787.aspx
But how can we handle a sharepoint list with these many large number columns.
Is it safe to create all columns in a single list?
How it will impact the performance?
What is the other approach acheive this requirement?
Any help would be appreciated.
Regards,
PooviHi,
According to your description, my understanding is that you want to know if it has some performance issue and limitation when create large number column in a list.
When creating columns in the list , you can still create all 320 columns in the list. But when retrieve the items in a view, then there is a list view threshold limit which causes the performance issue, see the link below:
Sharepoint list column limit
To handling the large number columns, I suggest you can distinguish the column with business logic to create in different list, it will be clear to display the logic relationship.
Thanks
Best Regards,
Jerry Guo

How to create and modify an XML file from an Oracle Form
I would like to build an Oracle Form to maintain a small XML file in the file system (i.e. Not in Oracle database but in the operating system).
I would like the Form to display existing values from the XML file and the user can update and save content back to the XML file.
Can any one tell me how this can be done? Thanks.Does Forms 9i provide any XML Parser Functions?
Can I insert the XML file into a table column by inserting XML using the XSU Front End rather than using TEXT_IO to maintain the XML file directly?
Can I use XSU PL/SQL API in Forms to retrieve and modify XML values?
Any help is appreciated. -
