         found=false;
         for(int j=0;j<b.length;j++)
                 if(a.equals(b[j])
found=true;
if(found==true)
System.out.println(a[i]+a[i]);

Your query is not pretty clear.
write the select query using Name = 'ANIL' in where condition and display the ouput using Control-break statements.

can you please tell me how to acheive 1,2,3 instead of the chars.
Also if I use virtual characteristic can I able to access the query structure in the user exit like the restricted key figures etc or just the records how they appear in the cube.
Thank you guys for the quick response.

Hello
I know that Pages is using its own algorithm to resize pages when it put several of them on a single sheet.
This is why I use this tip.
I draw a rectangle whose size is supposed to be the final one.
I give it a white background and a black border whose thickness is set to one point.
For the tests I just insert three page breaks so that the document is a four pages one.
I print it as is.
Doing that, I may measure the printed rectangle.
Of course, at first attempt it doesn't match the required size.
It's easy to compute the required adjustments.
When the correct factor is reached, it is easy to build the complete document so that it prints the correct size.
Doing that I never got odd results but maybe it's because I am a lucky guy.
Of course, disagreeing with one advice doesn't mean that I don't respect it.
I respect your opinion, _on other matters too_

How to print an output stream on console.

Hi,
I am new to JAVA. I am trying to execute a command in runtime and I want to print the output on console and also redirect the output to a file.
Could anyone please help me?
This is what I wrote :
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec("cmd /c ipconfig");I am getting an output stream by : proc.getOutputStream(). I dont know how to print it on console and also how to redirect it to a file.
Could anyone please help me.
Thanks in advance.
Basav

You can do it this way :-
     public static void main(String args[]) throws Exception {
          ProcessBuilder builder = new ProcessBuilder("ipconfig", "/all");
          Process process = builder.start();
          BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
          FileWriter writer = new FileWriter(new File("C:/ipconfig.txt"));
          String str;
          while ((str = reader.readLine()) != null) {
               System.out.println(str);
               writer.write(str + System.getProperty("line.separator"));
          writer.close();
          reader.close();
     }Let me know if it works for you.

How to loop an output array and pass each index to the next VI in the sequence in TestSTAND?

Hi,
I have 2 VIs - XX and YY. The output of XX generates an array of strings.
The input of YY takes in a string. I have VIs XX followed by YY in the
sequence editor.
For each item in the output array of XX, I want to pass that item into
YY and execute YY.
How do I do this in TestStand without creating an intermediate VI.
Your help is greatly appreciated folks!
Thx

Hi,
What you could do is set the second step to loop.
Then use as one of the parameters to VI YY the string array using RunState.LoopIndex as the array index.
eg. Locals.MyStringArray[RunState.LoopIndex]
Hope this helps

How to take this output from javacreator?

... What? Can you word that into a somewhat sensible English sentence? Are you trying to create that output? I assume javacreator = JCreator? Anyways... I would suggest starting with a for loop nested within another for loop. That would be your best bet in terms of difficulty to implement.
Hint: first for loop would be your max number, going down, nested loop should be for printing each line.

Hi,
user12240205 wrote:
... Frank, ʃʃp's method, I understand. But your method, although correct, I find it difficult to understand.
Could you explain how you did this?? What does '.*(\d{5})\D*' and '\1' mean???
Your method is better because it uses only ONE reg expression function. ʃʃp's uses 2.In Oracle 10.2 (I believe) and higher, '\d' is equivalent to '[[:digit:]]', and '\D' is equivalent to '[^[:digit:]]'. I find '\d' and '\D' easier to type, but there's nothing wrong with using '[[:digit:]]' and '[^[:digit:]]'.
'.*' means "0 or more of any character".
'\D*' means "0 or more non-digits".
The whole expression, '.*(\d{5})\D*' means:
a. 0 or more characters (any characters)
b. 5 digits
c. 0 or more non-digits.
'\1' is a Backreference . It means the sub-string that matched the pattern after the 1st '(', up to (but not including) its matching ')'. In this case, that means the sub-string that matched '\d{5}', or b. using the explanation immediately above.
So the entire REGEXP_REPLACE call means "When you see a sub-string consisting of a., follwed immediately by b., followed immedately by c., replace that sub-string with b. alone."

How to print console output

Hi, I have a JSP page and I would like to print STDOUT to the page. Is this possible?
I've seen a few methods and none work for me:

String input = reader.readLine();
out.println(input);*** Error: Type BufferedReader was not found.
FileOutputStream out;

                out = new FileOutputStream("myfile.txt");
                        // Connect print stream to the output stream
                        ps = new PrintStream(out);
                        ps.println ("This data is written to a file:");
            System.err.println ("Write successfully");
                        ps.close();
                catch (Exception e){

So what's next?
How can I call the console without writing to a file first?
I would like AJAX to show console output in real-time.

Thanks for your help.
The reason I have the script to write to a file is because it's the closest I could find to what I want. Ideally, I would be able to run a script that prints to the console but I want to grab the system.out going to the console and display it on the page.
Basically, I want the page to act as a console but not redirect the output (I want it to still go to the console) and I don't want it in a text file that the page reads.
So for example, the page loads and while that is occurring, the server grabs the console output and prints to the page. Then I run a function on the page that prints to the console and on the refresh, print the updated output. Ideally, I would restrict the output that was relevant to the page's functions and ignore every output to the console but I'm not (trying to be) picky.
So how would that work?
Pseudo-code:
for (int i=0;i < System.out().length(); i++) {
        String grabbedtext += System.out().toString();
}out.println(grabbedtext);
