How to create a text file with data.

Hi,
I am writing java code for testing an application, some times test can failed in some cases, I want to display an error message in text file. To that I written the code as like,
BufferedWriter bout;
bout =new BufferedWriter(new FileWriter("test.txt"));
String str=Your input data is not match with pattern
bout.write(str);but here it is creating a text file test without any data in it.
Can any body help that to execute the program properly
Regards

You didn't close your BufferedWriter. Since it's buffered it probably didn't write anything to the underlying file.
Generally you must close every Writer/OutputStream that you no longer use or it won't be written reliably.It's not quite as simple as that. If you have a chain of Writers / OutputStreams then you only have to close() the outer most one since each is responsible for closing any Writer/OutputStream that it wraps. If you do decide to close them individually (a bad idea but people do do it) then you MUST close them starting from the outer most one and working to the most inner one or you will not guarantee to flush any buffered content.Of course. I might have used a misleading phrasing here. What I meant is "Every time you are done with a Writer, you must close it" and not "You must close *every* Writer that you used". Thanks for the clarification.

How to create a text file or XML file and add content through code into it...

Hi Everyone,
How to create a text file and add content through the code to the text file eform javascript ......orelse can we create a text file in life cycle designer...

You can create a text file as a file attachment (data object) using the doc.createDataObject and doc.setDataObjectContents:

http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.528.html
You can then export the file with the doc.exportDataObject method:

This won't work with Reader if it hasn't been given the file attachment usage right with LiveCycle Reader Extensions.

How to create a csv file with NCS attributes?

Hi
i installed Cisco Prime NCS and trying to perform bulk update of device credentials with csv file.
How to create a csv file with all required attributes?
This is part of NCS online help talking about this topic:
Bulk Update Devices—To update the device credentials in a bulk, select Bulk Update Devices from the Select a command drop-down list. The Bulk Update Devices page appears.You can choose a CSV file.
Note The CSV file contains a list of devices to be updated, one device per line. Each line is a comma separated list of device attributes. The first line describes the attributes included. The IP address attribute is mandatory.
Bellow is test csv file i created but does not work:
10.64.160.31,v2c,2,10,snmpcomm,ssh,zeus,password,password,enablepwd,enablepwd,60
10.64.160.31,v2c,2,10,snmpcomm,ssh,zeus,password,password,enablepwd,enablepwd,60
The error i am getting while importing this file:
Missing mandatory field [ip_address] on header line:10.64.160.31,v2c,2,10,snmpcomm,ssh,zeus,password,password,enablepwd,enablepwd,60
Assistance appreciated.

It looks like the IP address field is incorrectly set.,
It should be as follows
{Device IP},{Device Subnet Mask}, etc etc
so a practical example of the aboove could be (i dont know if this is completely correct after the IP address / Subnet Mask)
10.64.160.31,255.255.255.0,v2c,2,10,snmpcomm,ssh,zeus,password,password,enablepwd,enablepwd,60

My problem:
1)
I am not able to write to the file. I want to know, where i am going wrong.
It is giving error message like
"Canot resolve Symbol: temp,"
But, FileWriter Constructor should accept a File type parameter.
here temp is a file parameter.
If i am not using file=new file();
i can't delete the file after the use. i.e if i use
PrintWriter p = new PrintWriter(new BufferedWriter(new FileWriter("cute.txt",true)));
how can i delete cute.txt after the use?
2)
I am not able to write to the text file. file is created but, a blank file.
"Hello" is not written into the text file.
can anyone help me in this regard
Thanks in advance
Ashvini

Thank you Ram,
But, i want to create a text file in Append mode.
for that i used
FileWriter fos = new FileWriter(temp,true); But, it is not accepting FileWriter constructor in
this format. if i use
FileWriter fos = new
FileWriter("c:/ash/cute.txt",true); it works fine. !!!!!Here's the javadoc
public FileWriter(File file,
boolean append)
throws IOExceptionConstructs a FileWriter object given a File object. If the second argument is true, then bytes will be written to the end of the file rather than the beginning.
Parameters:
file - a File object to write to
append - if true, then bytes will be written to the end of the file rather than the beginning
Throws:
IOException - if the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason
Since:
1.4
Are you using jdk.13 or lower ?
>
ONe more doubt, Does flush method deletes a file?
if not, then i need to use
File temp=new File("c:/ash/cute.txt");
FileWriter fos = new FileWriter(temp,true); //which
is again a problem
if(temp.delete())
out.println("File is deleted");
}I don't know whether i am taking it wrong ! or
anything wrong with my coding ! but, after creating
and writing data into a text file. I must delete it
as it contains confidential informations.
Regards,
Thanks.'flush' writes to a file immediately. Else you should explicitly call 'flush' to write contents from buffer to underlying source.
javadoc again
PrintWriter
public PrintWriter(Writer out,
boolean autoFlush)Create a new PrintWriter.
Parameters:
out - A character-output stream
autoFlush - A boolean; if true, the println, printf, or format methods will flush the output buffer
cheers,
ram.
Question; What do you gain by opening a file, writing to it and deleting it in the same program ?

How to Create a text file through Portal

Hi,
Is there any way to create a text file(e.g Excel file) through Portal? Thanks.
Sumita

I have a way to do this in VBScript, I don't know if it will work with the portal but the steps are simple. If you can create a text file within portal, try to create it as an html table:
<table>
<tr>
<td>Column Header 1</td>
<td>Column Header 2</td>
</tr>
<tr>
<td>Value 1</td>
<td>Value 2</td>
</tr>
<tr>
</tr>
</table>
When you create this file save it with XLS extension instead of TXT, create a link to it and voila! it will load Excel and you will have your data well formatted. I found this method rather better than save the file as a CSV. You can also include any html attribute inside the <TD> or <TR> like background color and font type, Excel will keep those attributes.
I hope this will help

How to creat a text file

hello everybody
I need your help guys in some java issue
"surprise"
how can I create a text file in java
I mean I wanna check if the file is there and if its not I create it
thanks

> mkdirs() only creates the parent directory structure
(may be needed as well).
Which is what I assumed at first, based on his report of an error message. However, now I'm not so sure, based on the OP's lack of detail. I can't tell if s/he's just not handling the exception (throws or try/catch), or if s/he is actually getting a "The system cannot find the path specified" message when attempting to create a file for which the appropriate directory does not exist (as is possible with createNewFile()).
It remains a mystery. :o)

How to create a text Component With Certain Properties

I need to create a text component with the following properties:
Has Capability to be italic, right/left aligned, have different background / foreground colors, and most importantly, the ability to have a fixed width and a height that is set by the amount of text in it (ie line wrapping expands the field vertically).
It should be a simple exercise, but I cannot seem to figure out how to do it.

Here is the correct syntax :
private static JEditorPane constructPane(String text, int normWidth, int normHeight, boolean rightAlign, boolean italic,boolean isWhite) {
          JEditorPane pane = new JEditorPane();
          pane.setEditable(false);
          pane.setContentType("text/html");
          pane.setText(
               "<html><head></head><body>"
               + (italic?"<i>":"")
               + "<table><COLGROUP><COL width=\""+normWidth+"\"><THREAD><tr><td valign=\"top\" align="+(rightAlign?"\"right\"":"\"left\"")+">"
               + text+"</td></tr></table>"
               + (italic?"</i>":"")
               + "</body></html>");
          pane.setSize(normWidth,normHeight);
          if(isWhite)
               pane.setBorder(BorderFactory.createCompoundBorder(BorderFactory.createMatteBorder(1,0,1,0,Color.WHITE),BorderFactory.createEmptyBorder(0,1,0,1)));
               pane.setForeground(Color.WHITE);
          else {
               pane.setBorder(BorderFactory.createCompoundBorder(BorderFactory.createMatteBorder(1,0,1,0,Color.BLACK),BorderFactory.createEmptyBorder(0,1,0,1)));
               pane.setForeground(Color.BLACK);
          return pane;
     }

Wondering how to create a text box with variables...

Hi everyone,
I was wondering how to create a text box, that at the beginning of the presentation, the audience fills in regarding what they think constitutes the role they have been chosen for.
I would like that same box to then appear at the end of the presentation, with the text they typed in at the beginning, so they can reflect on what they think now, and what they thought then. I understand this is done using variables, but i'm not 100% sure.
I hope I've worded this okay!

This screenshot shows the properties panel, Style tab for the TEB. I relabeled it to My_TEB, used the X button to create a user variable v_choice that will replace the generic Text_Entry_Box_1/
This is the properties panel of a Shape, I went in Edit mode (double clicking)to make the Character section appear, where you find the X button. It opens the dialog box 'Insert Variable' and you can choose the var associated with the TEB. The Maximum Length will define how many characters will be displayed, the value of a variable has maximum 256 characters.

How to create a .exe file with eclipse 3.1

Hello every body. I want to know how create a .exe file with eclipse 3.1. A friend tell me it's possible but he forgot how ! So I ask my question ay you, how can I do that? I think it's like in Dev-C++, when he compiling the programme he create

P.S : I'm a young french so maybe there are some mistake on my post. I hope you understand it.

There might be a plugin in eclipse to do this, but I don't know what it is.
The normal way to deploy a program is to create an executable jar file. This will be a .jar not a .exe.
Or you can try ggogle.

How to create a new file with existing file's resource fork?

Hello,
I would like to create a new file that has the resource fork of an existing file. I had though of making a copy of the existing file, seek to the beginning of the copy and write the new data, but for large files, that creates the whole file even when not needed. I currently create the new file with [NSFileManager createFileAtPath: contents: attributes:], but attributes do not include resource fork items, like custom icons, color label, etc.
[NSURL resourceValuesForKeys] gives a common subset of resource data, like icons and color label, but that's about it. Is there some way to get the resource fork or a copy of the file without getting the whole file?
Thanks

What are you trying to do here? While resource forks might still be quasi-supported, you really shouldn't be thinking about them as such. Instead, think in terms of extended attributes. You can use the low-level xattr() functions to get some of that or you can use the new NSURL methods.
