Different results using Matcher.replaceAll on a literal type of update
I expect the results for all of the following scenarios would have been the same:
public class {PatternMatcher
Public Shared Sub main (String [] args) {}
Model p;
Matcher m;
duplicates
p = Pattern.compile ("(.*)");
m = p.matcher ("abc");
If (m.matches ()) System.out.println (p + ":" + m.replaceAll ("xyz"));
unique
p = Pattern.compile ("(.+)");
m = p.matcher ("abc");
If (m.matches ()) System.out.println (p + ":" + m.replaceAll ("xyz"));
WTF
p = Pattern.compile ("(.*?)");
m = p.matcher ("abc");
If (m.matches ()) System.out.println (p + ":" + m.replaceAll ("xyz"));
duplicates
p = Pattern.compile ("(.*+)");
m = p.matcher ("abc");
If (m.matches ()) System.out.println (p + ":" + m.replaceAll ("xyz"));
unique
p = Pattern.compile ("^(.*)");
m = p.matcher ("abc");
If (m.matches ()) System.out.println (p + ":" + m.replaceAll ("xyz"));
duplicates
p = Pattern.compile ("(.*) $");
m = p.matcher ("abc");
If (m.matches ()) System.out.println (p + ":" + m.replaceAll ("xyz"));
unique
p = Pattern.compile ("^(.*) $");
m = p.matcher ("abc");
If (m.matches ()) System.out.println (p + ":" + m.replaceAll ("xyz"));
unique
p = Pattern.compile ("(.)) (. *).)");
m = p.matcher ("abc");
If (m.matches ()) System.out.println (p + ":" + m.replaceAll ("xyz"));
}
}
But the results vary depending on the type of update:
(. *): xyzxyz
(. +): xyz
(.*?) : xyzaxyzbxyzcxyz
(. * +): xyzxyz
^(.*): xyz
(. *) $: xyzxyz
^(.*) $: xyz
(. (.*).) : xyz
Because all models have a capturing group that covers everything, but the replacement string has no references of group, I expect that in any case the replacement string would simply be returned unchanged (so just "xyz").
I discovered a bug in the main library? or am I misunderstood how it should work?
Now for a real answer.
(. *) will produce two matches "abc" and "" (the end of the string) because the * means we can have zero. Idk if this is a standard regex, but it is this that java is. So let's replace it with "xyz" and produce "xyzxyz".
(. +) only has a game and works as expected
(.*?) is lazy and weird and will be 4 groups to capture anything. To see, ' | ' which is a capture ' |. ' a | b | c | ». so we will produce "xyzaxyzbxyzcxyz".
(.*+) Idk what it should even do lol
so on, etc.
All of this has to do with the fact that regex. * seems to act funny.

Flatten channel gives different results on a RT system compared to a Windows system?
When I flatten a structure moderately complex to a string in LabVIEW Windows, I get a slightly different result than when I do the same thing (interactive) Looking RT. LabVIEW to hexadecimal display produced channels, towards the tail end of the strings that I see:
Windows: A 999, 0000. FB99 A 9999 9999 9999 9, 00
RT: 9999 A000... FB99 9999 9999 99A 0 0000Shouldn't get the same value of the two systems?
Your problem is the use of the extended data type. I don't have a cRIO to do more thorough testing, but the only items that do not match are the two elements of smoothing. The two values differ by about - 5.54976E - 18 (that is to say, not much - less, in fact, the value of epsilon machine). If you use the context-sensitive help and hover on an EXT thread, you'll see a note indicating the precision varies by platform, so it must be provided. Also documented A in aid, under the heading "digital, data types table. Is there a reason why a double precision is not sufficient?

Why Express PSD gives a different result of amplitude as FFT PSD?
Hello
When I use the express VI of spectral measures to trace the power spectral density, I get a different result than when using the FFT PSD VI. The data are the same but the amplitudes are different in the PSD plot. Everyone comes through this?
Thank you
Donners,
The PSD2 and graphic PSD2 are different because you are breastfeeding two extra points in the tables (t0, df). When graphic entry of data in the tables, they interpret not automatically information of t0 and df. Actually they do not yet receive this information. You must program the scales with nodes of property. If you simply draw the order of magnitude, the spectra are very similar.
^ ^ ^ This confuses only the chart!
The spectral forms differ slightly as the power spectrum of FFT and PSD.vi uses a default Hanning window.

Different results from the the DLL source code
Hi all
I'm new to this forum and also to labview so understandable...
Then, I got a source project with many under vi of that graphic plots of excel files. I also got the exe after generation.
The problem is, if I try to compile this project again, the exe gives me different results than what I already have. They should be the same, because I does no update in the source code.
Can someone explain this behavior? I don't know anything about how it has been made because the guy who create this left the office... I need to make a few updates, but first of all, I have to build corectly.
Thank you
Have you compared the date of the exe file with the date of the source code? Are you absolutely sure that no changes have been made to the source code after the build? The construction specifications are part of the project. Unless you changed something there, builds should be the same.
You have the source code control? Issues like this should not be a if you make and use wisely.

Why can I get two different results from the same coefficients?
I get two different results of the evaluation of the polynomial function.
For the first, I get the coefficients of a polynomial function to adapt. I feed the coefficients of the function made the function Eval Poly and get the correct 12.8582 result when I evaluate 49940.
For the second, I create constant array of values that have been returned by the polynomial Fit function (I typed in). However, I get an incorrect result of - 120.7913 when I feed the constant table the function Eval Poly when I evauate 49940.
How this can happen when I use the same values in table?
A picture of what I explained is attached.
Hi Altran,

Display different results with if statements
Hello
I'm doing a very simple logic but can't figure out how to do visually in LabView. Please take a look in the file. As you can see on the right, I have a group of 9 possibilities, each of them being true I want the COMPOUND NUMBER indicator to show a different result. I tried to use the structure of the case, but I could not the icon of the indicator in other sous-schemas. I also thought about putting the results in a table and choose the element whereby the possibilities.
But I'm sure there is an easier way. Help, please.
Thank you
LD
You put the indicator of terminal outside the structure of the case. Then each case son its respective result in the tunnel leading out of the structure of the case to the indicator.
(Alternative, but not recommended, use a local variable of the indicator in all other cases, if you use the terminal in one of the cases.)

original title: a different output for ping - an IP address
I am trying to determine the name of the computer to an IP address
When I open a command prompt in a computer (Windows XP connected to our domain) and type ping - a [IP address], I get a result
When I open a command prompt in another computer (Windows Server 2008 connected to the WORKING group) and type ping - a [IP address], I get a different result
And there are other times when ping - [IP address] will display the name of the computer on a computer (usually the Windows Server 2008), but not the other
I tried to google
1. why this happens
2. what result is correct
Please specify.
The order of DNS in Windows name resolution is as follows:
- Name of the local host (file Hosts Local generally in c:\windows\system32\drivers\etc\hosts)
- Cache Client DNS resolution
- DNS server
- Cache of NetBIOS names
- WINS server
- NetBIOS broadcasts
- File LMHosts (same location as the HOSTS file)
The reason you get different results could be because machines could be on different subnets (different results for broadcast), using a different DNS server machines or are configured for different WINS servers, or the names are already cached because of prior activity.

Different results of exactly the same query
Hello
I wrote a function to calculate the days between 2 dates. If I am running in SQL Developer or directly on the oracle server, I get the results I expected. However, if I run on a client by using ODBC, or PHP connection via the OCI8 extension, I get an incorrect result.
The function takes 2 parameters: 1st and 2nd date and should output the number of non-working days (weekends and holidays) between 2 dates. The coding is not very pretty, but it does not work very well as I said since the client SQL Developer.
Here is the code:
The problem is only with certain dates. For example, if I use the date '17-SEP-2012' for the two input parameters, I'm waiting for a result draw. In the SQL Developer client, I get the expected result. However, using ODBC or PHP OCI8 (which I believe is using a direct connection to TNS in the DB), the result returned is '1', which is incorrect ("17-SEP-2012" has been a MONDAY ""). If I use the current date (20-SEP-2012), I get the expected (zero) result in both the SQL Developer client and ODBC/PHP client.create or replace FUNCTION NON_WORKDAYS(fromdate IN DATE, todate IN DATE) --Function to calculate non working days between 2 given dates (Weekends & Bank Holidays) --Update: Added in a calendar for bank holidays. Bank holidays are listed to the end of 2013 RETURN NUMBER IS BANK_HOLS NUMBER; ret NUMBER; BEGIN SELECT count(mydate) INTO ret FROM (SELECT TO_DATE (fromdate, 'dd-mon-yyyy hh24:mi:ss') + LEVEL - 1 mydate FROM DUAL CONNECT BY LEVEL < = TO_DATE (todate, 'dd-mon-yyyy hh24:mi:ss') - TO_DATE (fromdate, 'dd-mon-yyyy hh24:mi:ss') + 1) WHERE TO_CHAR (mydate, 'DY') IN ('SAT', 'SUN'); select count(mydate) into BANK_HOLS from ( SELECT TO_DATE (fromdate, 'dd-mon-yyyy hh24:mi:ss') + LEVEL - 1 mydate FROM DUAL CONNECT BY LEVEL < = TO_DATE (todate, 'dd-mon-yyyy hh24:mi:ss') - TO_DATE (fromdate, 'dd-mon-yyyy hh24:mi:ss') + 1 ) WHERE TO_CHAR (mydate, 'DD-MM-YYYY') IN ('03-01-2011', '22-04-2011', '25-04-2011', '29-04-2011', '02-05-2011', '30-05-2011', '29-08-2011', '26-12-2011', '27-12-2011', '02-01-2012', '06-04-2012', '09-04-2012', '07-05-2012', '04-06-2012', '05-06-2012', '12-07-2012', '27-08-2012', '25-12-2012', '26-12-2012', '01-01-2013', '29-03-2013', '01-04-2013', '06-05-2013', '27-05-2013', '12-07-2013', '26-08-2013', '25-12-2013', '26-12-2013' ); ret:= ret + BANK_HOLS; RETURN ret; end;
I also tried to use variants of SYSDATE in place and place the date string, to see if I get different results (i.e. today is 20-SEP-2012, so I used SYSDATE-3 to 17-SEP-2012).
To be clear, I call the function in a select statement: select (sysdate-3, sysdate-3) non_workdays of the double; or select non_workdays (TO_DATE('17-SEP-2012'), TO_DATE('17-SEP-2012')) of double;
I have spent hours and hours of troubleshooting this, and it makes me crazy!
I also checked the view V$ SQLAREA the Oracle DB to see what is actually passed to the ODBC client database engine. I was expecting the statement became corrupted somehow, that's why I get strange results, but this was not the case. The statement in the column SQL_FULLTEXT of V$ SQLAREA, showed exactly the statement I performed on the ODBC Client. I tried with the oracle instantclient and full client (10g).
Can someone help save my sanity please? I am eternally grateful!
Sorry for the massive post!
Published by: user12199535 on 20-Sep-2012 12:20Your code is a mess. You convert DATE to DATE, e.g. TO_DATE (fromdate, 'dd-mon-yyyy hh24:mi:ss'). TO_DATE function first parameter is a string, while fromdate is the date. That's why Oracle implicitly converts fromdate to the string of default date format that is client dependent and therefore can produce different results on different customers boxes. In addition, your code is dependent on NLS. If the customer has other date language settings, for example German, Sun and SAT are false. And there is no need to separately calculate the weekends and holidays:
create or replace FUNCTION NON_WORKDAYS(fromdate IN DATE, todate IN DATE) --Function to calculate non working days between 2 given dates (Weekends & Bank Holidays) --Update: Added in a calendar for bank holidays. Bank holidays are listed to the end of 2013 RETURN NUMBER IS BANK_HOLS NUMBER; ret NUMBER; BEGIN SELECT count(mydate) INTO ret FROM ( SELECT trunc(fromdate) + LEVEL - 1 mydate FROM DUAL CONNECT BY LEVEL < = trunc(todate) - trunc(fromdate) + 1 ) WHERE TO_CHAR(mydate,'DY','NLS_DATE_LANGUAGE = ENGLISH') IN ('SAT','SUN') OR mydate IN ( DATE '2011-01-03', DATE '2011-04-22', DATE '2011-04-25', DATE '2011-04-29', DATE '2011-05-02', DATE '2011-05-30', DATE '2011-08-29', DATE '2011-12-26', DATE '2011-12-27', DATE '2012-01-02', DATE '2012-04-06', DATE '2012-04-09', DATE '2012-05-07', DATE '2012-06-04', DATE '2012-06-05', DATE '2012-07-12', DATE '2012-08-27', DATE '2012-12-25', DATE '2012-12-26', DATE '2013-01-01', DATE '2013-03-29', DATE '2013-04-01', DATE '2013-05-06', DATE '2013-05-27', DATE '2013-07-12', DATE '2013-08-26', DATE '2013-12-25', DATE '2013-12-26' ); RETURN ret; end; /

Hello guys,.
I use integer variables, function and block. But I do not understand that they behave differently. For example, although the input variable type is integer, but it behaves like the number, however, when I declare an integer in block (a1), it is rounded to the whole number, I mean, it works correctly.
My question is what is the difference between these two integers? When I declare it in Notepad it working properly, however when I declare as a variable of office, it malfunctions?
And also, another interesting thing is function around return type but it returns number, how it is possible?
set serveroutput on; DECLARE a1 integer; FUNCTION plch_func1 (p1 INTEGER) RETURN INTEGER IS BEGIN dbms_output.put_line(p1); RETURN p1; END; BEGIN a1 := 0.54; DBMS_OUTPUT.PUT_LINE(a1); DBMS_OUTPUT.PUT_LINE(plch_func1(0.1)); END;

That even means. In any case, it is incorrect. The reason is defined in the connection of the doc Boneist under OP in. It includes an example that is identical to the example of PAHO.
>The reason for the result is described in the documentation. But the question I tried to answer one last by PO 'Why', why it is implemented this way?
So I can't answer for doing so at all, just a little fishing in the waters of kamel, but what exactly is not correct?
This is a setting IN, so that a reference is used. In the case of phenomenon couldn't happen, because an assignment is necessary before.
Of course there is no implicit type conversion because the integer it is managed internally as number.create FUNCTION plch_func1 (p1 IN integer) RETURN INTEGER IS BEGIN RETURN p1; END; desc plch_func1 Object Name Argument In Out Datatype PLCH_FUNC1

any advice appreciated...
JayMaybe you get different results because the data are different.
Also, why the first query uses a remote table, attached to a local table? Why not 100% remote data?

Connect Reporting different results to look at a pdf file
Through a program of training and receipt, a team of users is necessary to read a pdf file, close it, and then recognize their agreement with the terms in the pdf file. In order to show completed in the curriculum, all courses must be completed. The pdf is set up as a course and need to show as completed. I see the results of different people who consult this pdf file. Some users show over some not taken when they say they have opened the pdf file and found that it. This is a 2 page document. Of the reasons why we would get such different results? To get a complete users should consult the two pages? Other suggestions?
When I see this problem, it usually has to do with the conversion of the PDF file to allow the display of reports. Either re - download the PDF file and update the price or convert the document to HTML and use this current version. PDF conversion is random and frequent, but will allow some users to obtain a full and some show status does not matter how much the view the PDF.
