Returning positive value

hi again
in my main program - it displays all output to the MS DOS window box and all works fine
however in the GUI i wish to implement an error trapping where if for example the deltion/removal of an employee wasnt successful - it would display the appropriate message in the GUI - not the console however if it does remove it successfully it displays the default message
in the actual program the code works fine but may question is - how can i get feedback or something from my SoftwareHouse java file which has methods to remove employee?
so i can take the value in the SoftwareHouseFrame and deal with the returned value?
this is my code in the SoftwareHouseFrame for the inner class to remove the employee
System.out.println("Remove Employee");
String pnString = JOptionPane.showInputDialog(SoftwareHouseFrame.this, "Enter Programmer payroll number you wish to remove from the Software House", "Employee/Programmer payroll number", JOptionPane.QUESTION_MESSAGE);
int pn = Integer.parseInt(pnString);
SoftwareHouseFrame.this.theSoftwareHouse.removeEmployee(pn);
//need to get feedback from SoftwareHouse of successful deletion
JOptionPane.showMessageDialog(SoftwareHouseFrame.this,"Employee Removed", "information", JOptionPane.INFORMATION_MESSAGE);any ideas? do you understand what im trying to ask? :)

sure
//softwarehouse
    public final int    removeEmployee(int pn) {
        int removed = 0;
        //ConsoleIO.out.print("\nPlease enter the payroll number of the Employee you wish to remove >> ");
        //int pn = ConsoleIO.in.readInt();
        Iterator iter = theStaff.iterator();
        while(iter.hasNext() == true)
             Employee employee = (Employee)iter.next();
             //ConsoleIO.out.println("\n" + employee +"\n");
             if(employee.getPayrollNumber() == pn)
                  iter.remove();
                  removed = 1;
        if(removed == 1)
             ConsoleIO.out.println("Employee " + pn + " removed\n");
        if(removed == 0)
             ConsoleIO.out.println("\nSorry - there was a problem removing the employee. The Payroll number entered may have been incorrect");
    }

Cubeset to only return positive values?

Yet another cube formula question... In Excel 2010, no powerpivot or olap pivottable extensions, this is a pure Excel project.
I am building various cubeset, cubemember, and cubevalue formulas to validate an ETL process.
Question:
I need to create a cubeset that only returns the members of a cube that have positive values for a specific measure. This cubeset will then be one of several cubesets that gets fed into a cubevalue formula that would otherwise exceed the 255 char limit.
I can create a cubeset for the overall measure:
=CUBESET("MyCube","[Measures].[RetailPrice]")
but haven't found the right syntax for limiting results to only those that have positive values, I think it would be something like:
=CUBESET("MyCube","FILTER[Measures].[RetailPrice],[Measures].[RetailPrice]>0")
This syntax actually doesn't return an error, so maybe it is valid syntax... but when I wrap it in a simple cubevalue statement,
=CUBEVALUE("MyCube", A2) where A2 is the Cubeset above, or if I also add date range and other filters,
I get a #Value error, indicating that "the tuple is invalid" per
http://office.microsoft.com/en-in/excel-help/cubevalue-function-HA010342391.aspx?CTT=5&origin=HA010342384
I'm still a newbie with the cubeformula syntax and MDX, so I appreciate any suggestions!

Hi Rohit-
The cube has a net value of 1220 for the measure I'm trying to calculate (when I don't filter on > or < zero).
I tried my formula both ways (looking for just positive, and just negative values) and while both work in the standalone cubeset formula, neither return a value when I use it in a cubevalue formula.
My suspicion, other than a syntax error, is that this may have something to do with me trying to filter on the measure value(s), instead of a dimension- which I think must be possible, but again maybe not with this syntax.
Let's assume that we had a total of 1280 in retail price, but due to a few returns, we have a few records that show value of -60. If we were looking at profitability, the 1220 is what matters. If we are looking at "dollars exchanged" as a variable expense
driver of some other measure, then we'd actually want the absolute value of retail price (1280+60 = 1340). I hadn't been able to get the MDX ABS to work, so this was my attempt to grab the positive and negative numbers separately, and then add them to get
the equivalent of ABS.
In this case, slicers aren't a desirable option due to how the report is being constructed (I've used slicers in other reports with cubeformulas, but with Excel 2010 I have to have an extra pivot table to get the slicer value, which then has to get fed into my
cubeform and I'm back at step 1, getting it to work in the cubeformula syntax)
Thanks!

Generating subtraction equations that only return positive values

Hello!
Can you please help me to create a random subtraction equation where the result will always be positive? For example, my current scripting will return something lilke 3-6=-3. I don't want equations like this- only postive answers.
Thanks for your help!
//random numbers
//1.
function randomNumbers(min:Number,max:Number) {
   var Results:Number=Math.floor(Math.random()*max)+min;
   return Results;
//2.
new_mc.addEventListener(MouseEvent.CLICK, showRandomnumber);
//3.
function showRandomnumber(event:MouseEvent):void{
   r1_txt.text = String(randomNumbers(1,10));
   r2_txt.text = String(randomNumbers(1,10));
   a1_txt.text = String(Number(r1_txt.text) - Number(r2_txt.text));

I see.
How about you try to pass the first generated value the second time you call the function? Like so:
// Your function definition.
function randomNumbers(min:Number,max:Number) {
   var Results:Number=Math.floor(Math.random()*max)+min;
   return Results;
// Connecting the event handler.
new_mc.addEventListener(MouseEvent.CLICK, showRandomnumber);
// Check the r2 line.
function showRandomnumber(event:MouseEvent):void{
   r1_txt.text = String(randomNumbers(1,10));
   r2_txt.text = String(randomNumbers(1,r1_txt.text as Number));
   a1_txt.text = String(Number(r1_txt.text) - Number(r2_txt.text));
Ofcourse, this leaves you with the possibility that r2 is the same as r1, leaving 0 after subtraction. But it shouldn't give you any negative numbers.

FPGA returning negative values

Hello,
I have a question regarding an FPGA program,
the following attachments show the files and configuration I have been working on. When the laser light falls on the detector , the ADC converts to its values and gives me the output. And it returns positive values.
Everything was working fine and now it seems the opposite. When light falls on the detector it returns negative values and when there is less/no light, I get positive values.
I have no idea. why this is happening. Please advise.
PS : I can provide the program if necessary.

What changed when this started happening? Did you modify your experiment at all?
In my opinion the most likely situation is that the positive and negative analog inputs got swapped - is that possible? Are the wires somewhere that someone could have bumped them, and then plugged them back in to make it look like nothing happened but reversed them?

Photo:getRawMetadata( "gpsAltitude") always returns a positive value

I noticed, both on Windows 7 and Apple OS X 10.9 that calling the photo:getRawMetadata( "gpsAltitude") always returns a positive value.
Also when Lightroom in the user interface displays a negative value.
The strange thing is that the photo:getFormattedMetadata( "gpsAltitude") returns the right value, however formatted.
I reported the bug, see Lightroom 5 SDK photo:getRawMetadata( "gpsAltitude") gives always positive value also when it should be negative
I thought to document it also here for those who walk into this also.

Yes, this will be a good idea! Please include!
In general, if it will be possible to access (read/write) all EXIF tags with its name will be good. Also true for IPTC/IIM tags.
Maybe, what someone can do with Geo-Tagging, this external program can give some very good ideas: http://www.geosetter.de
A simple LUA scripts, which also uses the Exiftool can be found here:
http://code.google.com/p/geotag-lightroom-plugin/
But if sometimes LR will have functionalities like GeoSetter, this will be the best solution. Maybe, in a few years, every camera will have built-in GPS hardware, but if you look at GeoSetter, there is much more in Geo-Tagging than a GPS coordinate. I prefer, to have only one tool in my Workflow... And I like to see LR here. ;-)

by following function i will get 6 records by passing 6 programkeys and one biling key
now i need to get over all balance of all periods per program. condition is i need to take only +ve amounts from the below function and sum it up
expected out. i am just giving an example of output.

Issue with Report to get Position value for each Class ID.

Hello Experts,
m working on a report where I want Position values as on date.
for an entered date report should give position value(Amount for transaction) for each class Id.
I m trying using the exit variable but could not reach the output.
For date I created an exit variable which shoud return the latest position for each class Id.
Now this exit variable is "ready for Input" . when I debug my code it takes i_step =3 and i_vanm= " " after i_step = 1 and i_vnam = "<variablename>"
how do I go about to get the solution.
Guide me to come up with desired output.
Thanks in Adv.

How to get a function to return a value occuring after a character

I need to write a function to return the next value occurring after the ":" character in a column. If multiple values of ":" occurs then the function should return the sum of the next value occurring after each ":" in the column.
For example a rating value of 4:1 would return the value of 1. However, the rating of "5:1:1" should return a value of 1+1 = 2, and 6:2:1 will return of 2+1 = 3.
I have the below function skeletion and trying to figure out how the select statement will compute based on the position of : in the column and add the values and return the value back to function.

Hi,
You don't need a cursor: there's no table involved in this function, and no point in using any table.
Here's one way:
CREATE OR REPLACE FUNCTION fn_check_internalrating
(   p_internalrating   IN   VARCHAR2
,   p_delimiter            IN   VARCHAR2     DEFAULT     ':'
RETURN NUMBER
DETERMINISTIC          -- Same input always produces same output
IS
    cnumber     NUMBER     := 0;               -- value to be returned
    pos          PLS_INTEGER := INSTR ( p_internalrating
                                    , p_delimiter
                         );          -- position where delimiter was found
BEGIN
    WHILE pos != 0
    LOOP
        cnumber := cnumber + TO_NUMBER ( SUBSTR ( p_internalrating
                                              , pos + 1
                                     , 1
     pos := INSTR ( p_internalrating
                      , p_delimiter
               , pos + 1
    END LOOP;
    RETURN cnumber;
END fn_check_internalrating;
SHOW ERRORSThis assumes the function is a stand-alone function. If it's part of a package, you don't say CREATE OR REPLACE at the beginning.
Try to make functions generic, so that if a similar (but not identical) situation comes up in 6 months from now, you can use the same function. I'm guessing that somethimes you may want to do the same thing with some character other than ':' before each number, so I added the 2nd (optional) argument p_delimiter. You can call the fucntion with either 1 or 2 arguments.
If an error occurs in a PL/SQL fucntion, an error message (showing the exact location of the error) is displayed, and execution halts. If you use an EXCEPTION sectinn, you lose all that functionality, or have to code it yourself. Only use an EXCEPTION handler when you really have to.
For this function, you may or may not want to. For example, if the character right after a delimiter is not a digit, the call to TO_NUMBER in function will raise "ORA-01722: invalid number". You may want to catch that error in an exception handler, and return 0 or NULL. On the other hand, you may want to test that the character after the delimiter is a digit before calling TO_NUMBER, and not have an EXCEPTION section.
What else could go wrong? Try to think of potential problems and fix them when you first write the function. If you discover an error next year, you'll have to spend a fair amount of time finding the function, and getting acquainted with it again.
What should the function return if p_internalrating is NULL, or doesn't contain any delimiters?
What if there's a number longer than 1 digit after a delimiter, e.g. '6:78:9'?

Returning 2 values

so here's the problem: 'write a program to determine all pairs of positive integers(a,b) such that a<b<1000 and (a^2+b^2+1)/(ab) is an integer."
here's my pseudo code:
need to declare 2 integers a,b.
for all integers where a<b && b<1000
double c = (a^2+b^2+1)/(ab)
int d = (a^2+b^2+1)/(ab)
if c/d =1 then return a,b
actual code:
public class Basics {
     * chris
     public static void main(String[] args) {
          System.out.println(integ());
     public static int integ(){
          int a;
          int b;
          for(a=1, b=2; a<b && b<1000; a++){
               double c = (a^2+b^2+1)/(a*b);
               int d = (a^2+b^2+1)/(a*b);
               if(c/d==1){
               return a, b;
this is not for any class. it's winter break for us. so don't think you're giving away answer to some project by helping me. i really want to learn java. can anyone tell me how to return 2 values and if my code is good before the return statement?

thanks for the tip
public class Basics {
     public static void main(String[] args) {
          integ();
     public static void integ(){
          int a=1;
          int b=2;
          int[]myvalues = {a,b};
          for(b=2; b<1000; b++){
               for(a=1; a<b; a++){
               double c = (a^2+b^2+1)/(a*b);
               int d = (a^2+b^2+1)/(a*b);
               if(c/d==1){
               System.out.println(a+", "+b);
}now i want to know if my code is right. i would also appreciate if any decent java programmer come up with his program for this problem and explain the thought process so I can see what I'm doing wrong.
My thought process went something like this:
both have to be integers. so declare them as such. b has to be greater than a and we have to verify all integers below 1000. so start with a=1 and b=2. now create 2 loops that will go through all possible values for a and b and then verify(using if statement) if they satisfy the given condition.

Reg Exp always returning false value

Hi,
Below is my code. I want to restrict the values to only alphabets and numbers and not special char.
But the below condition fails on a positive value also. Ex: ABCD, abcd, 1234. These should be acceptable.
Is the reg exp wrong?

Can possible positive value of SQLCODE

Hi All,
Please let me know that, can possible positive value of SQLCODE and can I use SQLCODE, SQLERRM in user defined exception. Your suggestion would be greatly appreciated.
Edited by: user13842301 on Mar 18, 2011 8:53 AM

As per my knowledge, User cannot define positive error codes.
here is the snippet from oracle documentation -
The procedure RAISE_APPLICATION_ERROR lets you issue user-defined ORA- error messages from stored subprograms. That way, you can report errors to your application and avoid returning unhandled exceptions.
To call RAISE_APPLICATION_ERROR, use the syntax
raise_application_error(error_number, message[, {TRUE | FALSE}]);
where error_number is a negative integer in the range -20000 .. -20999 and message is a character string up to 2048 bytes long. If the optional third parameter is TRUE, the error is placed on the stack of previous errors. If the parameter is FALSE (the default), the error replaces all previous errors. RAISE_APPLICATION_ERROR is part of package DBMS_STANDARD, and as with package STANDARD, you do not need to qualify references to it.
where error_number is a negative integer in the range -20000 .. -20999

NSDecimalNumber returns positive number for "-10.045".

Hello,
I am developing iPhone application with UINavigationController. Today I noted that negative values stopped converted to negative numbers. Instead I started getting positive values.
I narrowed the issue down and I finally I get the code that shows the error:
NSLog(@"check negative %@ %@ ", @"-10.045", [NSDecimalNumber decimalNumberWithString:@"-10.045"]);
I dump that twice: when the app starts and when I click any button.
The output is following:
check negative -10.045 -10.045
check negative -10.045 10.045
So the first call returns correct value, the second one was not. That looks very very strange.
My environment: MacOS 10.6.7, Xcode 4.2 build 4C199, target iPhone 5.0 simulator.
I did not tested on read device, but when I changed target to iPhone 4.0 simulator, the issue was done.
Any ideas?
Regards,
Valery.

F4IF_INT_TABLE_VALUE_REQUEST - how can I return all values from the line?

Hi,
Use the structure DYNPFLD_MAPPING
With this internal table you can easily define that you want to return
other columns of the hit list in addition to field RETFIELD to the
screen.
In this IT you can MAP the screen fields to the serch help screen fields this has three fields
FLDNAME this is the field anme from the search help
FLDINH This has to be blank which would be field with the field value that you want to map
DYFLDNAME THis is the screen field name.
So here you can get the values for the other fields that you want which are on the search help just populate the name of the fields in FLDNAME.

What is reason for cl_fpm_factory= get_instance( ) return initial value?

In DEV system, this piece of code is working fine. However when it moves to Testing system it dump due to cl_fpm_factory=>get_instance( ) return initial value. What could be the reason for this? Thanks!
data lo_fpm type ref to if_fpm.
lo_fpm = cl_fpm_factory=>get_instance( ).
wd_this->go_message_manager = lo_fpm->mo_message_manager.

Hi Anthony,
how sure are you that the DEV and Test system running the same Netweaver SP versions ?. My doubt is that the test system is not NW7.01 (Ehp-1) . Or some thigs are not enabled in the configuration.
