How to read some images from file system with webdynpro for abap?
Thanks a lot!

Hello Tao,
The parameter
icm/HTTP/file_access_<xx>
may help you to access the pictures without any db-access.
The following two links may help you to understand the other possibilities as well.
The threads are covering BSP, but it should be useful for WebDynpro as well.

How to read a byte[] from a file

Hi can someone help me to read a byte[] from a file. I need to save a byte[] to a file and then retrieve it later can someone help in this..
Thanx

there are actually docs on the classes ByteArrayInputStream and ByteArrayOutputStream here:
http://java.sun.com/javase/6/docs/api/
go there (copy & paste in browser) and text search for the above classes.
Then read into it. That way, you will come to a better comprehension of the entire thing. You may as well want to read this:
http://java.sun.com/docs/books/tutorial/essential/io/index.html
And for the future: if you have general problems, search API docs and tutorials first and solve them yourself. The guys around here can get pretty annoyed about "Teach me the entire Java Thing" (also called "someone do my homework") requests.
If you have a special problem, ie an Exception you don?t understand or a method wich you don?t know how it works, everybody will like to help you.
Only few real serial killers frequent these forums.

How to read screendump image from clipboard to a file

I am trying to build a program that runs minimized while other programs are being used at the same moment. At certain moments I want to make a screenshot and save that information to a image file on the harddisk.
I have now the "user32.dll" to work and generate a "printscreen" push button. Now I want to write the information on the clipboard to an image file.
How can I read the information on the clipboard and use it in a VI?
Thanks in advance.
Ferry

If the screen you want to capture is a VI, you should use Invoke Node -> Get Panel Image, and Write BMP File.vi.
See attached VI.
If the screen isn't made in LabVIEW, and it's minimized, printscreen can't catch it.
To save the clipboard image to file, you can import the clipboard image into LabVIEW first
(use Image Toolbox: http://www.geocities.com/gzou999/imgtool.htm), and then Write BMP File.vi

How to read the data from excel file and store into the table?

Hi All,
I have table with BLOB datatype contains a excel file. I have to read that data from excel and store into one table with all the fields in excel.
All the excel fields and my table columns are same.
Can you share with me how can acheive this using LOB's?
Thanks

Hi OraSuirya,
you can try with external tables .
syntax as follows
create table ext_table_csv (
i Number,
n Varchar2(20),
m Varchar2(20)
organization external (
type oracle_loader
default directory ext_dir
access parameters (
records delimited by newline
fields terminated by ','
missing field values are null
location ('file.csv')
reject limit unlimited;
For this you need to create directory
Directory Creation syntax:
create or replace directory ext_dir as 'D:\oracle\user_dir\ext_dir';
grant read, write on directory ext_dir to <User>;
please paste the excel file in the particular directory .
I hope this will help you.
Please correct me if I am wrong anywhere .
Thanks,
Tippu.

How to read jpg image from a specified path

Hi
I am having an image in jpg ext, so i am using File nf = new File(path);to read the image, now i have to place that jpg image in an byte/String array so from that i will save that in to the Oracle DB with BLOB data type, plz answer to this asap with code......
the following code is not useful i think so...
     String st = "C:\Documents and Settings\Sasi\Desktop\sasi.jpg"
      File infile = new File(st);
     BufferedImage im = ImageIO.read(infile);
     String[] reader_names = ImageIO.getReaderFormatNames();plz reply to this asap,

byte[] buffer = new byte[infile.length()];Now use a RandomAccessFile to read the file into your byte array. [readFully(buffer);|http://java.sun.com/j2se/1.4.2/docs/api/java/io/RandomAccessFile.html]

How to read DES key from a file?

I stored the DES key in the file as follows:
KeyGenerator keygen = KeyGenerator.getInstance("DES");
SecretKey Key = keygen.generateKey();
FileOutputStream ostream = new FileOutputStream("t.tmp");
     ObjectOutputStream p = new ObjectOutputStream(ostream);
     p.writeObject(Key) ;
     p.flush();
     ostream.close();
I don't know if there is problem with the above code, I am just new to java cryptography.
I have problem read in the key and store it in the DES key object to be used for decryption.
Can someone please tell me how to do it and a simple example will be appriciated.
thanks
Jeff

Thank you for your help. after getting the key from the file( the output of the key is com.sun.crypto.provider.DESKey@fffe786d, not sure if it is right), I use this key to decrypt the message sent from the client program.
here is the code:
ObjectInputStream ois=new ObjectInputStream(data.getInputStream());
String c = ois.readLine() ;//should I convert the byte[] data to String?
ois.close() ;
jTextField1.setText(c) ;//display the cipher text to the first textfield
byte[] ciphertext = c.getBytes() ;
// System.out.write(ciphertext) ;
// get key from file
FileInputStream in = new FileInputStream("t.tmp");
ObjectInputStream oin = new ObjectInputStream(in);
SecretKey Key = (SecretKey)oin.readObject();
oin.close();
in.close();
System.out.println(Key) ;
//decrypt
Cipher C = Cipher.getInstance("DES");
C.init(Cipher.DECRYPT_MODE, Key);
// Decrypt the ciphertext
byte[] cleartext1 =C.doFinal(ciphertext);
System.out.write(cleartext1) ;//doesn't show anything!!
System.out.println("this is cleartexxt");//doesn't even show this!!
String display = new String(cleartext1);
jTextField2.setText(display);
why there is no output from System.out.write(cleartext1)? where did I go wrong?
thank you.
