How to Reread user inputs after detecting they're invalid
I was wondering if there was a way to redetect/reread user inputs once the original values were detected to be invalid? If I place everything in a continuous loop, i've tried manually pausing the vi. When I unpause the vi, it does reread the inputs. Any ideas would be appreciated. Thanks!
If the terminals were within a sequence within the loop, they still would have been read on every loop iteration, but maybe after you needed the updated value. Unless you had them in a case and the case wasn't selected on the loop iteration. There could have been several ways in which your program was structured so you wouldn't see the updated values when you needed them, but there was more to it than just having the terminals in the sequence. Just be careful that you have good control over when the updated values are read (e.g. using dataflow control) in relation to everything else happening in your loop.

How to get user input to keep in array in the form of int[]?
I really want to know how to get user input to keep in an array. Or if it's impossible, can i use the value in "int" and transfer it to an array?
What I understand is that you want to set an input from the user in an array of int.
Here is how it work:
1. Create a stream and a buffer to get and store the informations entered by the user:
BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));
2. Set this input in a String:
String input = stdin.readLine();
3. Set this string in an int:
int userInput = Integer.parseInt(input);
4. Then you can put this int in the array.
Warning this code throws IOExceptions and NumberFormatException ( when you try to set letters as int ). But you can catch them easily. -
How to capture user input for customer exit processing?
I need to calculate the number of working days elapsed in the current fiscal quarter BASED on the USER INPUT on the reporting front. i.e., say the fiscal quarter started on 1 July 2005 and if the user enters 10 July 2005, I should get the value 8 (Assume that Monday through Friday are all workdays). If the user enters 12 July 2005, I should get 10. I have written customer exits and know how to use factory calendar, but <b>THE CHALLENGE</b> is how do I <b>CAPTURE</b> the user input and use it in my exit? During the varible definition, if I select the check box "Ready for input" then the customer exit is not being processed and unless I check that box I can't get a user entry! If I look at the import values in the customer exit, I see i_t_var_range with type rrs0_t_var_range. My strong feeling is that this parameter gets the user input, but I am unable to use it as the customer exit is not being called if I make the user to input the data. Based on the empirical evidence, I felt that user input and customer exit can not co-exist!! Please somebody prove me wrong and let me know how can I use the user input to process my "customer-exit" variable. I would really appreciate any input from the BW community here.
Hi Sameer,
Most likely, I'm missing something, but I think that the answer is very simple.
CASE I_VNAM.
WHEN 'YOUR_CUSTOMER_EXIT_VAR'.
IF I_STEP = 2. After selecting of input variable
LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
WHERE VNAM = 'USER_INPUT_VAR'.
CLEAR L_S_RANGE.
L_S_RANGE-LOW = LOC_VAR_RANGE-LOW(4).
APPEND L_S_RANGE TO E_T_RANGE.
ENDLOOP.
ENDIF.
ENDCASE.
In this typical user exit coding you have a user entered value in LOC_VAR_RANGE (originally in I_T_VAR_RANGE) and you construct your user exit variable value in E_T_RANGE.
Best regards,
Eugene

How to accept user inputs from sql script
I want to create Tablespace useing sql script , but the location of the data file I need accept from user . (to get the location of the data file ) .
How can I accept user input from pl/sql .
Example :
CREATE TABLESPACE TSPACE_INDIA LOGGING
DATAFILE 'H:\ORACLE_DATA\FRSDB\TSPACE_INDI_D1_01.dbf'
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL;here I need to accept location of the datafile from user ie : 'H:\ORACLE_DATA\FRSDB\TSPACE_INDI_D1_01.dbf'Hi,
Whenenever you write dynamic SQL, put the SQL text into a variable. During development, display the variable instead of executing it. If it looks okay, then you can try executing it in addition to displaying it. When you're finished testing, then you can comment out or delete the display.
For example:
SET SERVEROUTPUT ON
DECLARE
flocation VARCHAR2 (300);
sql_txt VARCHAR2 (1000);
BEGIN
SELECT '&Enter_The_Path'
INTO flocation
FROM dual;
sql_txt := 'CREATE TABLESPACE SRC_TSPACE_INDIA LOGGING
DATAFILE' || flocation || ' "\SRC_TSPACE_INDI_D1_01.dbf" ' || '
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL ';
dbms_output.put_line (sql_txt || ' = sql_txt');
-- EXECUTE IMMEDIATE sql_txt;
END;
/When you run it, you'll see something like this:
Enter value for enter_the_path: c:\d\fubar
old 5: SELECT '&Enter_The_Path'
new 5: SELECT 'c:\d\fubar'
CREATE TABLESPACE SRC_TSPACE_INDIA LOGGING
DATAFILEc:\d\fubar
"\SRC_TSPACE_INDI_D1_01.dbf"
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE
UNLIMITED
EXTENT MANAGEMENT LOCAL = sql_txt
PL/SQL procedure successfully completed.This makes it easy to see that you're missing a space after the keyword DATAFILE. There are other errrors, too. For example, the path name has to be inside the quotes with the file name, without a line-feed between them, and the quotes should be single-quotes, not double-quotes.
Is there some reason why you're using PL/SQL? In SQL, you can just say:
CREATE TABLESPACE SRC_TSPACE_INDIA LOGGING
DATAFILE '&Enter_The_Path\SRC_TSPACE_INDI_D1_01.dbf'
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL;though I would use an ACCEPT command to given a better prompt.
Given that you want to use PL/SQL, you could assign the value above to sql_txt. If you need a separate PL/SQL variable for flocation, then you can assign it without using dual, for example:
DECLARE
flocation VARCHAR2 (300) := '&Enter_The_Path';The dual table isn't needed very much in PL/SQL.

How to control user input with a button?
How do I control a user input from a dialog box by activating it with a button. I am saying "press zero", then when the user does press zero, it should zero the scale.
The user has only one button they can press. You should enable the cancel so that the dialog can output an F.
What you have works, but the zero will not occur until the case is activated. If the insides of the case do not work, that is another story. Put a pop up in the active case to convince yourself that the case is being entered.
This, what you have, always returns T.

Well I'm new to Java, and I was trying to make a basic calculator to add 2 user inputs and give a total. Here is my code:
import java.util.Scanner;
public class calculator {
public static void main(String[] args) {
int total;
Scanner number1 = new Scanner(System.in);
Scanner number2 = new Scanner(System.in);
System.out.print("Enter your first number: ");
System.out.println(number1.nextLine());
System.out.print("Enter your second number: ");
System.out.println(number2.nextLine());
total = number1 + number2;
System.out.print("Your total is: " + total);
}And here is my error:
C:\Users\Jennifer\Desktop\Vincent's Things>javac calculator.java
calculator.java:13: operator + cannot be applied to java.util.Scanner,java.util.
Scanner
total = number1 + number2;
^
1 errorI tried giving it a cast, since it's saying Scanner's can't be operated, such as:
total = (int)number1 + (int)number2;But that didn't work. How can I make it so it adds the two inputs?A Scanner is a Scanner. Of course you can't just add two Scanners together. The Scanner could also be used to read text. A Scanner can't read your mind to know what type of data you are reading. You have to tell the Scanner what type of data you are reading. They way you do that is to read the Scanner API and use the proper methods.

Captivate 6 How to validate user input without using keyboard shortcuts
I've been using Adobe Captivate 6 for about 4 months now. Completely new to the program. The number one function of Captivate for me will to create many software simulations for verifiable training. This means that I will be utilizing the training and assessment modes A LOT. I have run into many hurdles throughout the process, but one of my biggies right now is this:
In the training and assessment modes, I have times where the user must input data such as an address or number. In the actual software they will be utilizing it is not always required to use TAB or ENTER in order to move to the next field. In some instances, it will be necessary to actually click into a field after entering data. My problem is that it seems as if Captivate will not allow this, as a keyboard shortcut is automatically entered even if a TAB or ENTER is not required after input. I assume this is so that the inputted information can be verified. If you decide you do not want to use a keyboard shortcut to validate the inputted information, you must have a submit button. Is there any way to change this?? All I want is for the user to enter information and then click into another field WITHOUT having to press ENTER, TAB, or hit a submit button. Is this even possible if you need user input to be validated?? Any ideas or suggestions would be much appreciated!!Hello,
A while ago I explained the work flow I’m using often in that case, only for the last field you need to have either a shortcut or a submit button AND the sequence has to be imposed. The idea is that you make the Submit button for the first field transparent, delete the ‘Submit’ text and put it over the second field. So if the user clicks on the second field, he also submits the value of the first field.
Here is the blog post I’m referring to:
http://lilybiri.posterous.com/one-submit-button-for-multiple-text-entry-box
Although it was written for previous versions, the idea will still be functional.

How to save User input into DB using webdynpro abap
Hi,
Im trying to create an application using webdynpro abap.
I want to know how to save the data input by user, into a database table.
In my UI, I have a table control which is editable and user inputs data into this. I need to know how i can transfer this data to a DB table.hello,
u can do it by reading ur context node.
we bind our UI elements to context attributes of appropriate type .
we read their values using the code wizard or by pressing control+F7, click on radio button read node/attribute
here for ur specific case , u must have binded ur table control with the context attribute , now u need to simply read this attribute
eg suppose u have created a context node " cn_table"
reading context node cn_table
DATA : lo_nd_cn_table TYPE REF TO if_wd_context_node ,
lo_el_cn_table TYPE REF TO if_wd_context_element ,
ls_cn_table TYPE wd_this->element_cn_table.
* navigate from <CONTEXT> to <CN_TABLE> via lead selection
lo_nd_cn_table = wd_context->get_child_node(
name = wd_this->wdctx_cn_table ).
** get element via lead selection
lo_el_cn_table = lo_nd_cn_table->get_lead_selection( ).
lo_el_cn_table->get_static_attributes( IMPORTING
static_attributes = wa_table ).
here wa_table is the work area of structure type . u need to create a structure first with the same variables as there are the context attributes in ur node cn_table
in ur
now ur wa_tablecontains value
u can nw use appropriate FM to update , delete and modify the DB table using the value
u cn directly use SQL statements as well in the method of ur view , but direct SQL statements are nt recommende

How to validate user input field?
I need to validate a user input field against a table. This field is not part of an EO but is used to update an attribute on an existing EO.
My question is, where would I place the sql that would validate the user input value against the table?
Is there an easy way to do this?
I'm at a roadblock and really need some help. Thank you.You can execute a sql query or a function from <your>AMImpl.java, using normal jdbc.
but I would recommend this, it is easier and cleaner approach
1. Create a VO (<your>VO) with the sql statement
Select client
from client_table
where resp_id = :1
and client= :2
2. Add this vo to the am
3. In AMImpl, get handle to the VO (this.get<your>VO1)
4. Bind params
this.get<your>VO1().setWhereClauseParams(0,current_resp );
this.get<your>VO1().setWhereClauseParams(1,user_input_value);
5. Execute the query
this.get<your>VO1().executeQuery();
6. Get the row after the query is executed
oracle.jbo.Row <your>Row = this.get<your>VO1().first();
7. Get the value of the attribute from the row
l_client = <your>Row.getAttribute("Client") ;
8. So now you have what you wanted to do with the sql.
Thanks

I know how to use the Keyboard class to prompt user input, but if I want to create custom user arrays, can anyone help me go about how to do it?
I want the user to be able to specify an array between 100 and 200 characters ins ize, and I'd create an array like that according to the user input...I don't have a clue how I'd even begin this though...Please help.If I understand correctly: take user input as an int and create an array of that size? if so:
int size = parseInt( args[0] );
ObjectName nameOfArray[] = new ObjectName[size];
args is (almost) always a string array so you need to extract the int value (parse it). that simple :) -

How to total all inputs after looping?
Hello, new user here. I've just started doing loops, but am have a little problem that I hope you can help me with.
I want to loop a program to input the commission figures for ten people, then calculate and output the total commission overall, as well as the average commission too.
I currently have the below code. But I do not know how to store one input somewhere, and then store the second input, etc, and then add these inputs together at the end. Any help is greatly appreciated! Thank you =)
import java.util.Scanner;

class Payslips
public static void main (String[]args)
Scanner input = new Scanner(System.in);
int x;
double commission, total, average;
for (x = 1; x <=10; x++) //will loop up to 10 times
System.out.println ("Input commission"); //outputs text
commission = input.nextDouble();

initialize toal to zero
inside the loop , add commision to total.
Once the loop is over , you have the total value in the variable 'total'.
Divide total by the number of times looped to get the avg.
