No, that defeats the purpose of a public forum. And no one is going to e-mail you (other than someone trying to sell V1AGRA).

Can some body help me to develop labview code for generating pulse to drive ac servo motor

can some body help me to develop labview code for generating pulse to drive ac servo motor... i am using NI 9401 card ....tnx

Driving an AC servo motor would (I missed AC on the previous msg) requires some complex hardware. This is generally done by drivers specifically designed for this purpose. I doubt you will be able to accomplish this with the hardware you currently have and it might be cheaper to just buy a driver for it and control the speed through the driver.

Tips on how to write efficient java code for java mapping

hi
I do not have much knowledge in Java
Can anybody tell me some tips on how to write efficient and optimised java code to be used in java mapping
Thanks,
Loveena

hi D'za,
JAVA in xi
A very important place where you will use JAVA in XI is while doing your Mapping. There will be cases when JAVA MAPPING is the best solution to go for. There are 2 types of Parsers available for JAVA Mapping. DOM Parser and SAX parser. Just got through the following links to understand more on Java Mapping and the APIs available.http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/parsers/package-summary.html http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/Document.html http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/package-frame.html /people/prasad.ulagappan2/blog/2005/06/29/java-mapping-part-i

Please help regarding a PL/SQL Code for padding of digits

I have a table named as EWT_POL_AGT_REL. There is column named PDT_AGENT_NBR present in this table. The data type of this column is
VARCHAR2(8 byte). There are some records in with pdt_agent_nbr having 8 spaces and some starting with zero such as “08400”. So I want
to do following things 1.)left-append a '0' in front of the existing 5 digit PDT_AGENT_NBR and make it to 8 digits 2) if the existing PDT_AGENT_NBR is already 8 digits, do nothing 3.) if it contains leading spaces then replace them by zero.
Sceanrios
if PDT_AGENT_NBR is " 12345" then i should get "00012345"
if PDT_AGENT_NBR is "1234" then i should get "00001234"
This table has nearly 180 million records hence an update query will not work. Instead a PL/SQL procedure needs to be developed.
Please help me on this. Please

This table has nearly 180 million records hence an update query will not work. Because..................?

How to write the SQL query for generating triangular numbers

Hi,
I have a table ..which stores the sequence number like this
Seq :
1000
1200
1300
1500
1800
1900
Now i want to get a result like this
1000 1000
1200 2200
1300 3500
1500 5000
1800 6800
1900 8700
how can it be achieved. I tried using Lead and lag. but only I can add the n+1 or n-1 results. Please help.

I've never heard it called 'triangular numbers' before but I think you're looking for a 'running total':

Please help me whit this java code

Hi!
I have a litle problem whit this question:
I try to write a program about Salary. The user writes(puts in from keyboard)
the workers name, hourePayment and hour(how many hours He has worked).
The program must compute first week ,second week....fourth week
The user writes just one time name and hourPayment,
but he must write hours(total hours he has worked)
for every week(may be ha has worked 30 hours first week and 40 hours second week.....).
when the user puts in zero the program stops(while(hour!=0)).
I wrote the program but I have problem whit
Test class when the program computes first ,second and...weeks, and if the user don not put in zero the program must compute another persons salary
we should give new name new houre payement....
how do I use the same information for second person and computes his salary.
class Salary{
private String name;
private double hourPayment;
public Salary (String name, double hourPayment, ..){
this.name= name;
this.hourPayment=hourPayment;
public String getNamn(){
return name;}
public double getHourPayment(){
return hourPayment;
public double compute(int time){
if(time<=40){
normalSalary =(hourPayment*time);}
else if(time>40){
....=(((40*hourPayment)+(time-40)*(3/2)*hourPayment));
else if(timmar>70){
System.out.println("WARRNING:"+" "+"You have worked more than 30

The code you wrote only computes one week's salary. You need to wrap that inside loops that collect names, rates and hours. Here's some pseudocode to get you started:
get name
while name NOT ""
    get rate
    for i = 1 to 4
        get hours worked
        compute pay // this is the part you've coded
    next i
    get name
end while

Being picky, that's not C++, that's C. Standard headers in C++ dont' have .h after them, loop variables are scoped with the for, you use constants rather than #defines, etc..
C and C++ both don't initialise arrays by default; you'd have to write an initialiser to get it to zero out the array:
int s[sz][sz] = {};gcc will insert a call to memset to zero the array.
If the author was assuming that the array was zeroed out, there would be no point zeroing the first row and column.
The code reads values which haven't been initialised. If you mark such values explicitly undefined, and change the program to report an error when undefined, then you get several cases where the program makes such report.
So either it' s a primitive random number generator (some random number generators use uninitialised memory as a source of randomness), or it's buggy, or it's processing undefined data and throwing away the result. Either way, it cannot be directly be ported to Java if the undefined values (which are limited to a small area of the ouput) are significant.

I Need Java code for following Algorithm

* I Need Java code for following algorithm. Kindly any one help.
1. Read the contents (ideas and its corresponding scores) from two files named as 'a' and 'b'.
2. Stored the file 'a' contents in array a[].
3. Stored the file 'b' contents in array b[].
4. compare both files like
if(a.equals(b[j])
Writing the common idea and add the score from file 'a' and 'b'.
else
write the uncommon idea and its score..
For example :
Form Agents.txt
action,65
architecture,85
eco-,15
essay,30
form,85
form,85
link,40
tangent,25
Form Agents1.txt
Black holes,69
essay,78
Herewith i have above mentioned two files named as Form Agents and Form Agents1.
Form Agents has eight fields
Form Agents1 has two fields
--> 'essay' is common in two files, so store the idea 'essay' and add the score from Form Agents score is '30' and Form Agents1 has 78 (essay 108).
Finally it stores idea in another file with uncommon fields also.
Please help us.

We have tried with following code.
But we cant add the scores.
For Example:
Form Agents.txt --> has "essay,30"
Form Agents1.txt --> has "essay,78"
Result is: essay,108
Finally it stores idea in another file with uncommon fields also.
So Any one pls correct the following code.

Okay, first suggestion is to never create database connections in JSP/Servlet. SInce you mentioned MVC, JSP is the View, and a servlet can be the controller to process requests and redirect accordingly.
This piece of code should be in a class invoked from the model layer (business logic components) preferably with some abstraction. Maybe you should search around for DAO pattern. That might give you an idea.

Your question still does not make any sense, and you still haven't clarified what you're not understanding.
However, if you think that just by reading the API docs, with no other training or study, that you will be able to write that code, then you are seriously misunderstanding the purpose of the docs.
Obviously English is not your native language. You grew up speaking some other language at home and with your friends, and at some point in school or as private study, you started to learn English. You learned about the grammar and the alphabet and pronunciation, sentence structure, word order, etc. Now you have the basics of how the language works, and you know some words. When you want to learn new words to fit into the structure you have learned, you use a dictionary.
If you didn't study the grammar, sentence structure, etc., and just said, "I want to learn English. I will look at a dicationary," clearly that would not work.
Right?
So, since you now understand and agree with the English example, let me state something that I hope is obvious to you by now: The API docs are your dictionary. They are not a substitute for learning the language basics.
Furthermore, once you know the language basics in English and have your dictionary, you still won't know how to write a resume (which you may know as a CV). You will look at examples and perhaps take a course on resume (CV) writing. Just reading a dictionary won't help you write a resume(CV). Similarly, if you know some Java basics, you can't learn how to write a Swing app just by reading the Javadocs. You'll look at tutorials and examples. Then, once you know the basic structure of a Swing app, you'll look to the javadocs for more details about more kinds of GUI classes--different buttons and windows and panes and panels and layout managers, etc.
