How can i read header text?

how can i read header text?
ie, i want to read two values that are stored as header text in purchase order.
how can i retrieve that values?

Hi,
The long texts of a document are stored in a encrypted format in the STXH and STXL tables, where STXH stores the header information of the
long text like TDOBJECT, which indicates which text object the long text belongs to, TDID which indicates the Text ID and TDNAME which is
the actual name of the long text.
As these texts are stored in a encrypted format, the text cannot be read using a SELECT statement. You will have to use the function READ_TEXT. The easiest way of getting to know the parameter values is to go to a document, open the long text in a full screen mode. For example, when you wan to see the long text for a Purchase order, go to transaction ME23n. Assume, you want to see the parameters for the Header Text. In the first Tab Strip Control, click on the Texts tab and select the Header Text node on the left hand side, which will display the text on the right hand side. Now, double click on the text editor on the right hand side. This will open the text in the full screen mode. In the menu Go To --> Header, you should be able to see the values for all the three parameters we discussed above. We will have to do the same thing for whichever text parameters we want to see.
TREC-TDSPRAS = SY-LANGU.
TREC-TDID = 'ECCS'.
TREC-TDOBJECT = 'ZECCS'.
TREC-TDNAME = Z_ACCOUNT.
CALL FUNCTION 'READ_TEXT'
EXPORTING
ID = TREC-TDID
LANGUAGE = TREC-TDSPRAS
NAME = TREC-TDNAME
OBJECT = TREC-TDOBJECT
TABLES
LINES = LINES
EXCEPTIONS
ID = 1
LANGUAGE = 2
NAME = 3
NOT_FOUND = 4

When I print a webpage from FF how can I make the text and images bigger?

I am trying to print an eticket for a flight. The text on the schedule comes out too small and the UPC symbol's black lines look ganged together. I know I can view it zoomed up, but how do I make the text and images stay zoomed so they will print out that way?

I upgraded but the problem remains. At least with Firefox I do have the option to print a selection even if it mangles the top and bottom lines. With Safari or Chrome I have no option to print a selection. At the moment the only way to get a complete copy of the selection is to copy to openoffice etc and print from there.

What I wanna do is to read all the data above and buffer them in a queue for each user( there are only 10 users in total).
I already created a class called Class packet:
public class packet {
    private int timestamp;
    private int user_id;
    private int packet_id;
    private int packet_seqno;
    private int packet_size;
    /** Creates a new instance of packet */
    public packet(int timestamp,int user_id, int packet_id,int packet_seqno, int packet_size)
        this.timestamp = timestamp;
        this.user_id=user_id;
        this.packet_id=packet_id;
        this.packet_seqno=packet_seqno;
        this.packet_size=packet_size;
}then I wanna to create another Class called Class user which I can create a queue for each user (10 users in total) to store type packet information. the queue for each user will be in the order by timestamp.
any idea and sample code will be appreciated.

Doesn't sound too hard to me. Your class User (the convention says to capitalize class names) will have an ArrayList or Vector in it to represent the queue, and a method to store a Packet object into the List. An array or ArrayList or Vector will hold the 10 user objects. You will find the right user object from packet.user_id and call the method.
Please try to write some code yourself. You won't learn anything from having someone else write it for you. Look at sample code using ArrayList and Vector, there's plenty out there. Post in the forum again if your code turns out not to behave.

How can I read only text files in a directory.

I've written a program to read files in a directory but I'd like for it to only read the text files of that directory.
import java.io.*;
public class Data {
public static void main(String[] args) throws IOException {
String target_dir = "C:\\files";
File dir = new File(target_dir);
File[] files = dir.listFiles();
for (File textfiles : files) {
if (textfiles.isFile()) {
BufferedReader inputStream = null;
try {
inputStream = new BufferedReader(new FileReader(textfiles));
String line;
while ((line = inputStream.readLine()) != null) {
System.out.println(line);
} finally {
if (inputStream != null) {
inputStream.close();

You have mentioned you want to read only text files.
If you are referring to some specific set of extentions, you can filter based on that.
ex: you want to read only .txt files, you can add an if condition as below :
if(textfiles.getName().endsWith(".txt")) {
// Add your code here

How can i read data in pagemaker file (PMD) using Visual Studio C# NET ?

I have bunch of data in .PMD file (Page Maker Document). Which contains mathematical equations and chemistry formulas, I am a .NET developer, and I am writing code for one of the educational learning system. For that I need to read and store mathematical equations/ chemistry formulas from .PMD file into database then display on the browser page.
Is it possible to read data from .PMD file using C#.NET, do I need to use any external libraries. How can I import .PMD to MATHML (Mathematical Markup language)?
Any existing examples for C#.NET?
Please help me regarding this.

I can't claim to know much about visual C# Net, but I do know a bit about pagemaker. It really can't handle equations. there are a few work arounds involving things like baseline shifts and multiple text boxes, but generally equations were created in different programs and placed in pagemaker in picture or eps files. Either way the chances of extracting usable data out of pagemaker is very slim.

How can I read a text file inside the .xsjs?

I need to read line by line of a text file just like FileReader and BufferedReader in Java. It contains a script SQL to insert data in my DB. Can I use some API?

There is no API that allows you to access the file system of the server in XSJS. You would need to upload the file from the client side and it will appear as a array buffer in the request object. From there you can convert the array buffer to a string and process however you like.
For example:
var content = "";
    content = $.request.body.asArrayBuffer();
    var array = new Uint8Array(content);
    var encodedString = String.fromCharCode.apply(null,array),
         decodedString = decodeURIComponent(escape(encodedString));
        content = decodedString;
    var lines = content.split(/\r\n|\n/);

How can I read the text in this .tar?

On my MacBook Pro running10.6.8...
I have downloaded a file named "ascii2html-0.0.1.tar.xz" from a Unix site that is supposed to contain both source code and binary. I'm interested in reading the source code, which I assume is in text.
Doubleclicking on it launches Stuffit Expander V10.0 which says it does not recognize the file's format.
I downloaded Stuffit Expander V15.0.7 which also cannot recognize the format.
I found an "Archive Utility.app" in /System/Library/CoreServices, but I cannot figure out how to invoke it. Double-clicking on it launches terminal; after that, entering "man Archive Utility" doesn't seem to do anything.
I also verified that /usr/bin/tar exists (it's an alias to /usr/bin/bsdtar) ad so does /usr/bin/gnutar, if that helps.
Any ideas?

How can we read and write data into plist using javascript in a html5 widget to be implemented into iBooks?

I had been trying to read from a plist to get file names of data files and it works fine when i run it in safari but after making its widget and putting it into iBooks it doesnot works. Please tell me any new method to read p list or correct my function if there is any correction. my function is following.
function plistread(n)
          if (window.XMLHttpRequest)
               xhttp = new XMLHttpRequest();
           else
        xhttp = new ActiveXObject("Microsoft.XMLHTTP");
               xhttp.open("GET", "Spell_Check_3.plist", false);
    xhttp.send();
    xmlDoc = xhttp.responseXML;
    var x = xmlDoc.getElementsByTagName("dict");
    var imgnamex = x[n].getElementsByTagName("string")[0].childNodes[0].nodeValue;
    xlength=x.length;
          return imgnamex;

See i need to access a plist file in my html5 widget, i implemented it in java script but it's not working so is there any other way to take out values from a plist file.

How can I read a TDMS 2.0 file using nilibddc.dll

I have written some Matlab software to read TDMS files into Matlab using the MATLAB TDM example and the nilibddc.dll. However, when I create a TDMS version 2.0 file with Labview 2009 I cannot read it into Matlab as I get the error
ERROR: TDS Exception in Initialize: Tds Error: TdsErrFileVersionTooNew(-2510)
Is this due to the versioning of nilibddc.dll and if so when will this be fixed? I understand that I could convert the TDMS file to version 1.0 however this is impractical and time consuming given the large number of TDMS files that I am dealing with.

How can I create a Text-Input Field in BexAnalyzer for a Planning Function

Hello,
i want to create a pre calculation(contribution accounting) for Materials in BI-Integrated Planning. These Materials aren't in the master data. So I create a new Info Object for pre calculated materials with only a material-number as key and a text-description.
Now I want to write a Exit-Function, which creates new materials in these Info Object. The user should start this function in a planning application in BexAnalyzer. There the user should have the possibility to enter a text-description for the new material. How can I create such a Text-Field in BexAnalyzer and how can I read this text filed in a planning function (exit).
Thanks in advance

Hi Jürgen,
you can create a parameter for this in the exit function and a variable for the parameter. In BEx Analyzer then create a button for the planning function; in the button parameterization use VAR_NAME = , i.e. use an Excel formula here to get the value from an Excel input field.
The command range should be some 'hidden area' in your Excel sheet.
But may be you don't need this. Use a characteristic without master data. Then ensure that that the query uses the option 'key' as display. In new lines you can then enter the key, the system creates a SID on the fly (but the text table will not be updated). In this scenario you may take text also from the key. May be you can update the text table (online or in batch) by simply using function modules from function group RSNDI_MD (not released by SAP).
But observere that the system in BI Planning reads only the active version, i.e. if you change something on the fly the changes may not be visible.

Gregor

How can I read a comment from an lvm?

Hello,
I created an lvm using the Write to Measurement File express vi and I added a comment.
To simplify it the line of the lvm created was:
5 test
where 5 is a random value and test the comment I input.
My question is how can I read this comment.
When I use the Read Measurement File express vi, the comment output
returns empty.
Thank you.
Solved!
Go to Solution.

Hi epik78,
I am not sure how you are adding your comment to the file, but when I made the simple VI below, I was able to see the comment that I input to the .lvm file in the comment indicator of the Read From Measurement File.

Stephen S.
