Questions on HR-OM programming

Hello, I have to get several data from HRP* tables. I'm quite new to HR so I have this questions.
1) Which is the proper way to use BEGDA and ENDDA? I mean, if i'm provided a date or a date range to get the objects, how to use them as condition?
2) I've been searching for a while and found that using function RH_READ_INFTY is always preferable over accessing HRP* tables directly.
However, there are a couple of issues with this function module given it's scarce documentation:
How do I get several records which fit some condition? I mean, for example I want to get Job families (JF) 10000000 through 10001000. Do I have to make 1000 individual function calls?
How to use the CONDITION and EXTEND parameters?
Any useful information you can provide on this function module or its related ones will be helpful.
3) Is there another way to access all this information? I've seen the PCH LDB is available but I don't fully understand how it works and if it will provide all information needed...
Many thanks

EDIT: Solved myself using f.m. RH_CONDITION_BUILD.

Question RE: Security/Virus Program for Macbook Pro

Greetings,
I was wondering if you would recommend Avast 2014 Antivirus Software protection for the macbook pro. If not, is there any other programs and/or other applications I should know about or use to help with viruses and security? I was also considering Norton.
Thank you in advance for any help and/or any advice.
Christian

Hi Christian,
I was wondering if you would recommend Avast 2014 Antivirus Software protection for the macbook pro.
Absolutely not. Older versions of Avast were garbage that would do nothing beneficial. Their most recent version is arguably malicious. Norton / Symantec is worse. Install none of that junk.
You may be considering them due to a familiarity with their equivalent PC products, in which the case for advocating their use may be entirely different - I'm assuming that is the case since no knowledgeable Mac user would ever consider either product. For all I know their Windows PC products may be reputable.
is there any other programs and/or other applications I should know about or use to help with viruses and security?
"Anti-virus" software serves no purpose on a Mac and is a common cause of problems reported on this site. OS X already includes everything it needs to protect itself from viruses and malware. Automated means of protecting your Mac from malware are an ineffective defense against that threat. At best, they will provide a false sense of security, a threat all to itself.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac, or to make it "shiny". Those claims are absurd.Such products are very aggressively marketed. They are all scams.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.
Illegally obtained software is almost certain to contain malware.
"Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Java can be disabled in System Preferences.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

Newbie Question: How to organize program with lots of components

Hi,
After struggling through the basics of Swing programming, I've finally got my application to look like what I want. Now I have to deal with all the inputs and variables (which is the hard part ^_^).
I wonder how people usually organize numerous components and action listeners? I have a lot of fields that have to be synchronized frequently with a hardware device, and they are also adjustable by a number of menus.
Currently I've just stuffed all the listeners and actions as inner classes in my main display frame. I am hoping to create a separate class that can manage all these actions, or a more elegant way to organize my program.
For now I'm reading up on MVC (Model View Controller). Is that a good place to start? Or how about XML?
I know this isn't a very specific question, but I'd appreciate a push in the right direction ^_^
Thanks!
Cindy

I would look at MVC and its part - Observer pattern.

Question mark for a program

I downloaded a program from Safari a few days ago, but a question mark appears whenever I turn on my Macbook. However when I click on the program, the actual icon (not the question mark) appears...
I redownloaded the application to check but the question mark happens to reappear...

Does the program still work?
If it has a question mark then it could be that the file was in a format not supported by Mac OS.
Out of curiosity (hope I spelled that right) What program was downloaded?

I have many questions about this program, but let me ask this one first:
In the TrueFalseQeustion class, why are there so many constructors? What is the purpose of setting some of the variables to default values?
Thank you very much!!!

} I don't understand why the assignment wants me to build a method in the MultpleChoiceQuestion class to store the potential answer choices, I can make the program display the potential answer choices by including them in the questionText as following in the QuizDriver class
Question x;
x = new MultipleChoiceQuestion("What is the color of the car\na.Red\nb.Green", "a. Red", 3);
t.addQuestion(x); I don't know how to allow the client to construct the list of answer choices one at a time(add one potential answer choice by calling the addAsnwerChoices() method once)
Here are a few original sentences of my assignment which describe what I should do with the MultipleChoiceQuestion class
Using TrueFalseQuestion as a model, develop a new MultipleChoiceQuestion class that can be used to represent a problem where the user must select one of several answer choices (e.g., "Select answer (a), (b), (c), or (d)."). This new question type should have all of the same externally-visible functionality as TrueFalseQuestion, except that it must:
maintain a list of potential answer choices
provide a method that allows the client to construct the list of answer choices one at a time (i.e., the client should be able to call an addAnswerChoice() method to pass a new answer option to the MultipleChoiceQuestion.)
display (as part of the question text) the list of answer choices with appropriate letters ("abcd" instead of "0123") I don't understand what these sentences mean.
1. "Maintain a list of potential answer choices"-- this reminds me of the getPossibleAnswerChoice() method in the TrueFalseQuestion class
public String[] getPossibleAnswerChoice ()
 String[] possibleAnswerChoice = {"true", "false"};
 return possibleAnswerChoice;
 }I wonder that if the potential answer choices I have to store in the MultipleChoiceQuestion class are only letters "a", "b", "c", "d", etc, or include the answer text coming after the letters(eg. a.Red, b.Green)
2. "provide a method that allows the client to construct the list of answer choices one at a time". How do I achieve the functionality "one at a time"? Do I need to pass the input of the client (a potential answer choice) to the variable of the method which stores the list of potential answers?
3. "display (as part of the question text) the list of answer choices with appropriate letters". My question here is that: When the client type in one possible answer, should I append it to the variable questionText? (So I use the questionText variable in the methods of the first and second steps)
Thank you very much for your nice help!

[SOLVED]Questions about a shell program and about shell: files, regexp

Hello, I'm writing this little program in shell:
#!/bin/bash
# Synopsis:
# Read from an inputfile each line, which has the following format:
# lllnn nnnnnnnnnnnnllll STRING lnnnlll n nnnn nnnnnnnnn nnnnnnnnnnnnnnnnnnnn ll ll
# where:
# n is a <positive int>
# l is a <char> (no special chars)
# the last set of ll ll could be:
# - NV
# - PV
# Ex:
# AVO01 000060229651AVON FOOD OF ARKHAM C A S060GER 0 1110 000000022 00031433680006534689 NV PV
# The program should check, for each line of the file, the following:
# I) If the nn of character lllnn (beggining the line) is numeric,
# this is, <int>
# II) If the character ll ll is NV (just one set of ll) then
# copy that line in an outputfile, and add one to a counter.
# III) If the character ll ll is NP (just one set of ll) then
# copy that line in an outputfile, and add one to a counter.
# NOTICE: could be just one ll. Ex: [...] NV [...]
# [...] PV [...]
# or both Ex: [...] NV PV [...]
# Execution (after generating the executable):
# ./ inputfile outputfileNOM outputfilePGP
# Check the number of arguments that could be passed.
if [[ ${#@} != 3 ]]; then
echo "Error...must be: myShellprogram <inputfile> <outputfileNOM> <outputfilePGP>\n"
exit
fi
#Inputfile: is in position 1 on the ARGS
inputfile=$1
#OutputfileNOM: is in position 2 on the ARGS
outputfileNOM=$2
#OutputfilePGP: is in position 3 on the ARGS
outputfilePGP=$3
#Main variables. Change if needed.
# Flags the could appear in the <inputfile>
# ATTENTION!!!: notice that there is a white space
# before the characters, this is important when using
# the regular expression in the conditional:
# if [[ $line =~ $NOM ]]; then [...]
# If the white space is NOT there it would match things like:
# ABCNV ... which is wrong!!
NOM=" NV"
PGP=" PV"
#Counters of ocurrences
countNOM=0;
countPGP=0;
#Check if the files exists and have the write/read permissions
if [[ -r $inputfile && -w $outputfileNOM && -w $outputfilePGP ]]; then
#Read all the lines of the file.
while read -r line
do
code=${line:3:2} #Store the code (the nnn) of the "llnnn" char set of the inputfile
#Check if the code is numeric
if [[ $code =~ ^[0-9]+$ ]] ; then
#Check if the actual line has the NOM flag
if [[ $line =~ $NOM ]]; then
echo "$line" >> "$outputfileNOM"
(( ++countNOM ))
fi
#Check if the actual line has the PGP flag
if [[ $line =~ $PGP ]]; then
echo "$line" >> "$outputfilePGP"
(( ++countPGP ))
fi
else
echo "$code is not numeric"
exit
fi
done < "$inputfile"
echo "COUN NON $countNOM"
echo "COUN PGP $countPGP"
else
echo "FILE: $inputfile does not exist or does not have read permissions"
echo "FILE: $outputfileNOM does not exist or does not have write permissions"
echo "FILE: $outputfilePGP does not exist or does not have write permissions"
fi
I have some questions:
I) When I do:
if [[ -r $inputfile && -w $outputfileNOM && -w $outputfilePGP ]]; then
else
echo "FILE: $inputfile does not exist or does not have read permissions"
echo "FILE: $outputfileNOM does not exist or does not have write permissions"
echo "FILE: $outputfilePGP does not exist or does not have write permissions"
fi
I would like to print the things on the else, accordingly, this is, print the right message. Ex: if "$outputfileNOM" did not have the write permission, just print that error. BUT, I don't want to put a lot of if/else, Ex:
if [[ -r $inputfile ]]; then
if [[-w $outputfileNOM ]] then
else
For the READ permission, and the other for the WRITE
Is there a way to do it, without using a nesting approach, and that maintains the readability.
II) About the:
if [[ -r $inputfile && -w $outputfileNOM && -w $outputfilePGP ]]
is OK if I use the flag "-x" instead of -r or -w. I don;t have a clear definition of what is the meaning of:
-x FILE
FILE exists and execute (or search) permission is granted
III) Notice the ATTENTION label in my code. I notice that there are some possibilities, for ex: having white spaces before, after or before or after. I'm believing in the consistency of the input files, but if they change, it will explode. What could I do in this case? Is there an elegant way to manage it? (exceptions?)
Thank you very much!
EDIT: corrected what rockin turtle wrote bellow about the format. Thank you.

I) Regarding your if statement, you could do something like this:
estr='FILE: %s does not exist or does not have %s permissions.\n'
[ -r $inputfile ] || ( printf "$estr" "$inputfile" "read" && exit 1 )
[ -w $outputfileNOM ] || ( printf "$estr" "$outputfileNOM" "write" && exit 1 )
[ -w $outputfilePGP ] || ( printf "$estr" "$outputfilePGP" "write" && exit 1 )
II)The -r/-w/-x mean that the file has the read/write/execute bit set. Do a
$ man chmod
for details.
III) You should be able to do
if [[ "$line" =~ .*\<NV\> ]]; then
echo "..."
(( countNOM++ ))
fi
but that didn't work for me when I tried it. I don't know if this is a bug in bash, or (more likely) something that I am doing wrong.
Regardless, I would write your script like this:
#!/bin/bash
file=$(egrep '^[A-Z]..[0-9]{2}' "$1")
grep '\<NV\>' <<< "$file" > "$2"
grep '\<PV\>' <<< "$file" > "$3"
echo 'Count NON:' $(wc -l < "$2")
echo 'Count PGP:' $(wc -l < "$3")
Note: In reading your script, your comments imply that each line of the input file starts with 'llnnn' but the example line you gave starts with 'lllnn'. That is, there are 3 letters (AVO) followed by 2 numbers (01). The above script assumes that lines start with 'lllnn'

Touchsmart screen flickering and questions on upgrading what program computer runs...

Hello,
I have a HP Touchsmart IQ506 that is running Windows Vista. I posted on the 18th of November that the screen started flickering after the computer ran and installed an update. I went through that were given to me and even did a full system recovery on it. It quit flickering for a couple hours and now its back! My only guess would be that since I purchased this computer back in 2007 and it went back to the factory settings, it had a lot of updates (138 of them) after I did the system recovery. Is there any way to check what update is causing this flickering?
The other question would be can I go buy Windows 7 or Windows 8 and install it on this computer? I wasn't srue since I am running Vista and this computer probably has some extra programs that make the "touch" part of it work. Didnt know if there was a special Windows 7 for touchscreens or Windows 8 for touchscreens.
Your help is very much appreciated!
Thanks,
Ashley

Hello Ashley
Many all in one computers I have worked with before have limited internal space due to it being conformed to fit a smaller case; as such, many all in ones utilize laptop (or similar to laptop) hardware.
After looking into your problem further, I located a firmware update for your video card that is intended to fix a flickering issue. (Firmware is like a BIOS for a device; the instructions are saved directly to the video card)
NVIDIA GeForce 9300M GS Graphics Firmware Update
As for the driver install message you are receiving, did you try using the Auto Detect video card feature? I also found a video on YouTube that appears to be a great tutorial for getting the installer to find your video card. How to Fix NVIDIA Driver Update Installer Error
Reading some of the comments might help as well, some users have posted their experiences and tips.

Question about automatic payment program

Hi Experts,
Need your help to solve below issue.
Compmnay code "1111" is central compasny code,which is making payments to vendor "dddd" through automatic payment program on behalf of other company codes(2222 and 3333).
Issue1:Company code "1111" has open item 1000 with respect to vendor "dddd" and company code "2222" has open item 3000 with respect to same vendor.
when i execute APP it is issuing two different checks though vendor is same.Single check should be issued as per my requirement.
Let me know about the configuration.
issue2: Compnay code has "1111"credit memo amount 10000(debit balance) in vendor "yyyy" in the year 2010 and since 2010 no invoices in comopany code "1111" but company code "2222" has invoice amount 15000 for the same vendor.
My requireemnt is check shoud be issued for the amount ( after diducting credit memo amount from invoice amount) in APP.
Please let me know about configuration.
Regards,
Uma

Hi Expert,
To pay with one check, you need to the below configuration. Go to T-Code:OBVU and do the below steps, according to your requirement.
and Select payment method supplement (check box)
Specify the sending company code if you want to pay using a cross-company code transaction but do not want to pay the items of all participating company codes together.
Examples
Example 1:
Company code 0001 pays its own items and the items of company codes 0002 and 0003. All items are grouped into one payment.
Company code Paying company code Sending company code
0001 0001 0001
0002 0001 0001
0003 0001 0001
Example 2:
Company code 0001 pays its own items and the items of company codes 0002 and 0003. However, a separate payment is created for each company code.
Company code Paying company code Sending company code
0001 0001 0001
0002 0001 0002
0003 0001 0003

Advanced question for running DOS programs on a Mac.

So what is a simple process on a Windows machine seems to be a challege on my new Mac.
In summary I have several hard drives laying around that need to be checked for problems before they are used. There are lots of free DOS programs available for PCs that do just that. Many are provided directly by the hard drive manufacturers themselves (ie Segate SeaTools) and they are fantastic. Macs unfortunately can't run DOS programs (without hacks like rEFInd) and none of the manufacturers provide Mac compatible software. Looking on the internet everyone points me to Disk Utility to check drives, but compaired to something like SeaTools, Disk Utility is useless. I found Micromats TechTool Pro 6 which comes close to what I need except its expensive and has lots of features I don't need.
I want to avoid installing windows in bootcamp or a VM just to do this one simple task. Very frustrating that it seems like im the only one wanting to do this with a Mac.

Did some more research and figured out these are my options:
-Find a mac alternative (few out there, most very bacic, or very expensive)
-use rEFInd (which is in beta, and modifies OSX)
-bootcamp (which doesnt allow BIOS access to select a dvd DOS program, so doesnt help. Also, mac doesnt use legacy usb and keyboard drivers so you cant use keyboard/mouse in most DOS programs)
-Vmware
So to me my best option was to use Vmware. Installed on a USB hard drive to save space and configured VMware bios to boot from selected .iso of a disk and it worked. Successfully ran SeaTools and because VMware emulates legacy mouse/keyboard it worked.
One problem though. SeaTools for DOS doesnt work from USB sata adapter, and considering its a macbook air im out of luck.

Question About Installing Individual Programs in Final Cut Studio 2

I recently installed Final Cut Studio 2, but I chose not to install Livetype on the initial setup. Now I would like to install it, but was curious why it seems to be installing all the information from the other programs I installed last week. Only Livetype was available on the "Custom Install" screen, it was blue and checked. Everything else was greyed out, but still checked. However, it seems to be repeating the same install process I did previously; and I am curious if this is going to create any redundancies on my computer. Any help?

Thank you for your quick response David!
1. Great! Glad that worked out.
2. When I say FCS 2 I mean the suite that came with Final Cut Pro 6, DVD Studio Pro 4, Motion 3, LiveType 2, Soundtrack Pro 2, Color, Compressor 3. I'm pretty sure it will play nicely with a new intel machine.
When I say FCS HD I mean the suite that came with Final Cut Pro (5.1.4), DVD Studio Pro, Motion 2, and Soundtrack Pro, and Compressor 2. This version (5.1) was made to work with intel machines.
3. Thank you also for providing the link! I definitely want to make sure this is legal.
Much appreciated

Question about java threads programming

Hi
I have to develop a program where I need to access data from database, but I need to it using multithreading, currently I go sequentially to each database to access data which is slow
I have a Vector called systemnames, this one has list of all the systems I need to access.
Here is my current code, some thing like this
Vector masterVector = new Vector();
GetData data = new GetData();
For(int i =0; i < systemnames.size(); i++)
masterVector.add(data.getData((String)systemnames.get(i));
public class GetData
private Vector getData(String ipaddress)
//process SQL here
return data;
how do i convert this to multithread application, so there will be one thread running for each system in vector, this is speed up the process of extracting data and displaying it
has any one done this kind of program, what are the precautions i need to take care of

Process Chain Review Question: function module/ABAP program/Event

Hi,
1. Can you tell me a bit more about function modules such as RSPC_CHAIN_ACTIVATE_REMOTE
2. What are function modules in general terms. i.e. What is their role?
3. How do I see all function module available?
4. When is function module used instead of ABAP program?
5. How do they help in the support and monitoring of Process Chains?
6. I am getting confused over the following under process chains job, event, function module and ABAP Program
Thanks

2. What are function modules in general terms. i.e. What is their role?
Function module return a value ( most of the time), they return some value either a single value of rane of value or even a table. Example: FM to return fiscal period gieven the fiscal vaeiant and system date.
3. How do I see all function module available?
Go to Se37 and this is function builder. You will find FM starting with RS* more useful. You cna also create your own in Se37.
4. When is function module used instead of ABAP program?
In addtion to answer I gave in 3 above, program is used to check some logic and update some tables or give screen output.
You may note FM is also a program.
5. How do they help in the support and monitoring of Process Chains?
As I said, for monitoring chains, use Sm37 and logs in RSPC.
6. I am getting confused over the following under process chains job, event, function module and ABAP Program
I am not clear what are you looking for.
You cna schedule a FM or a program to run in a chain. Is that what you mean?

Round trip workflow with proxies between Premiere and AE / a more general question about how these programs work?

Hi all,
I'm new to editing with proxies in Premiere and have some questions about how to handle the relationship with After Effects. Say I have a rough cut (with proxies) and I want to send it to AE to do some effects. The simplest thing to do seems to be to replace the proxies with the originals in Premiere, send the project to AE and do my thing. But if I then want to send the project back to Premiere, it will involve the original files, which are too machine-intensive for me to edit. In theory, it seems like there should be a way to send the project with original footage to AE, do effects, send it back to Premiere, and then replace it with proxies to do further editing while retaining the effects.
This leads to a confusion about how AE works. When I do an effect, am I correct in assuming that it does nothing to the original file? If that's the case, it seems like it shouldn't matter (in the editing stage) what file AE "applies" an effect to (proxy or original). But I feel like there's a hitch in this workflow. The same question could also be asked about going back and forth in Speed Grade.
Perhaps there is no real answer to this and the best option is to save effects and grading for after I have picture lock, but sometimes that's not entirely possible or convenient, etc.
Hopefully this makes some sense—It's a little hard to explain.
Thanks.

Dumb question- how to install program?

i've had this computer for awhile and never really had to do it. I think I've done it wrong a few time actually. It's a .dmg file, and when I click on it it opens a folder with a link to the program, some read me files, plug ins, accessories folder. I seem to recall when I first got the computer them telling me that I had to drag something into the applications folder and then delete the rest?

There are two standard procedures for installing software on the Mac:
1. drag the application icon from wherever it is (say, in the virtual disk that appears when you clikc ona .dmg file) to /Applications
or
2. If the file is a package/installer (looks like a box with stuff in it), double-click on the file and follow the prompts.
