Question about hidden directories

Whenever I am using a CPP program and it crashes it brings up information about the crash and points to a director that isn't existant. It says like C:\Somedirectory\file.cpp, how come it points to a non existant directory? Or is it there but I can't access it?

A couple of things you need to know.
- a CPP program is a program which was compiled from C++
- This is a Java Programming forum and is for Java Programming related questions.
- The error message refers to where the cpp source was when it was compiled on the machine it was compiled on. IF you knew which machine that was and the source has not been moved you would be able to find it.

Question about classes/Directories

I've been using Java to learn programming for a while now, so this question may not belong here. It seems to be more of a general question, however, not code related.
How does java work with directories? Say I had a project, and for some reason I wanted different java class files to be in different directories. How does java handle this? Say for example:
1.) Main class is in C:/blahblah/Project/ and the other classes were in C:/blahblah/Project/src/?
2.) Main class is in C:/blahblah/Project/src/ and the other classes were in C:/blahblah/Project/?
3.) Main class is in C:/blahblah/Project/src/ and other classes were in C:/blahblah/Project/bin/?
I know these may be kind of stupid examples, but I just wanted to know how such things worked for future reference. Thanks a ton!

Question about hidden files..!!

I have an external hard disk and kept one folder in hidden state(in windows). Now I connected that drive to Mac Book and unable to see the hidden folder. How to get that?

If you looked closely while in Windows, all the files you can't see had a name that began with a dot. In Unix, OS X's underpinnings, those files are considered invisible and do not show up in the graphical interface.
Either get an alternate Finder-equivalent utility or use Terminal and Unix shell commands, such as ls -a

EmieSiteList and EmieUserList
Microsoft Security - Privacy Concerns
I found two unknown directories on my PC in my user profile. I have, so far, been unable to identify what put them there, which process owns them, and when I delete them (using Admin escalated privileges) they come back after a few minutes or immediately
after reboot.
     c:\users\USERNAME\appdata\local\EmieSitelist\container.dat
     c:\users\USERNAME\appdata\local\EmieUserlist\container.dat
     C:\Users\USERNAME\AppData\LocalLow\EmieSiteList\container.dat
     C:\Users\USERNAME\AppData\LocalLow\EmieUserlist\container.dat
It was time, anyway, so I wiped the drive using factory low-level overwriting and performed a clean install of Windows 8.1 Pro using a freshly downloaded ISO from Microsoft; one with an ESD distribution, written to a new just out-of-the-bedamned-hardshell-plastic
flashdrive..
I just completed the clean install, in this sequence:
Boot to flashdrive and let Windows create partitions then install. Reboot. Check AppData; no folders found.
Activate. Check AppData; no folders found.
Run first Update; install everything except Bing Bar and Desktop.    Check AppData; no folders found. Reboot. Check AppData; no folders found.
Add Feature Windows Media Center. Check AppData; no folders found. Reboot. Check AppData; no folders found.
Run Updates a second time. Check AppData; no folders found. Reboot. Check AppData; no folders found.
Remove MS C++ v12 x86 and x64 installed during Update.    Check AppData; no folders found. Reboot. Check AppData; no folders found.
Download from MSDN (http://msdn.microsoft.com/en-us/vstudio/default) Redistributables MS C++ x86 and x64, 2005, 2008, 2010, and 2012.4 versions, and install in sequence. Check AppData
after each install; no folders found. Reboot after each install and check AppData; no folders found.
Run Updates a third time. Response was No Updates Available. Check AppData; no folders found.
Reboot. Check AppData; all four sub-directories are now present.
These sub-directories and dat-files are not, so far, present in the AppData\Roaming directory.
There is nothing except Microsoft Windows 8.1 Pro WMC and the 10 MS C++ packages installed; and MS Silverlight and AMD (videocard) Catalyst Control Center on the machine. Windows Defender is present but is installed as part of Windows 8 and 8.1;
and its' updates are provided via the MS Update process. All - repeat ALL of these items are provided by Microsoft.
My questions are: What are the Emie directories for; what program created them, and what does the various container.dat files "contain"? And . . . if not absolutely necessary, How do I get rid of them and keep them from coming back?
First attempt at Solution:
Permissions are Full for System, USERNAME, and group Administrators. The USERNAME is the Owner, and Effective Permissions for each of the 3 is Full.
Open Command Prompt (Admin)
C:\Windows\system32>cd\
C:\>attrib -r -h +s C:\Users\USERNAME\AppData\Local\EmieSiteList\container.dat
C:\>attrib -r -h +s C:\Users\USERNAME\AppData\Local\EmieSiteList
C:\>attrib -r -h +s C:\Users\USERNAME\AppData\Local\EmieUserList

C:\>attrib -r -h +s C:\Users\USERNAME\AppData\LocalLow\EmieUserList
C:\>attrib -r -h +s C:\Users\USERNAME\AppData\LocalLow\EmieSiteList
C:\>attrib -r -h +s C:\Users\USERNAME\AppData\LocalLow\EmieSiteList\container.dat
C:\>
BOTH Files and Directories are no longer Hidden. The Directories still show that the files within are READ-Only, but checking the actual file shows that it is no longer R-O.
I then deleted each of the 4 directories and closed Windows (File) Explorer.
After less than 3 minutes reading pages on the internet (at Microsoft's Ask Windows Community), I opened Windows Explorer to check and found that the sub-directories had re-created themselves in both the Local and LocalLow directories.
The container.dat files were back in the Local sub-dir and after another few minutes, also back in the LocalLow sub-dir.
Both the sub-directories and the container.dat files are once again Super-Hidden.
Analysis using Windows utilities and SysInternals and NirSoft tools have not identified which object or process or service owns these objects.
ADDED: My system is a home system, not connected to any work domain via VPN or otherwise. WHY is the Windows Update Team not spending time to implement condition-and-error-checking to ensure that unneeded updates, services, and changes are not made
without the system owner/operator permission? Further, WHY is this particular issue so hard to find info about; what is being kept from customers and why?

Internet Explorer 11 (on Windows 7 and Windows 8.1) provides increased performance, improved security, and support for the modern technologies like HTML5 and CSS3 that power today’s Web sites and services. By adding better backward compatibility with
Enterprise Mode, Internet Explorer 11 now helps customers stay up to date with the latest browser—and facilitates using the latest software, services, and devices.
IE11 Enterprise Mode can be set in the Group Policy Console, or by adding a

Basic Questions About Compiling Source

Hi!
I have some very basic questions about compiling source on 10.6. BTW, if the unix discussions still exist, they've hidden them pretty well, so I hope I'm in the right place for this!
First off, you simply cd to the source dir, wherever it may be - in my case ~/Downloads/source/ - and during the install process, everything will be installed in its proper dir, right?
How do you know which compiler to use? There seem to be several: make, gmake, gcc, g++, etc...
Once you do figure out which compiler to run, the process is supposed to go like this, right?
./configure
make (or whatever)
make install
But this doesn't always work for me. For instance, I'm trying to compile 'arm', but it doesn't seem to have a 'configure' script.
$ ls ~/Downloads/arm
ChangeLog
README
armrc.sample
setup.py
LICENSE
arm
install
/src
Maybe it's that 'setup.py' file? What are you supposed to do?
Of course, it's not only this one that's given me trouble. Sometimes the readme will say I have to edit a certain file for my system. Are there just a few standard changes you always make? Or is it...how can I put it...complicated? How do you find out what's needed in those cases?

This is the place for UNIX discussions. If you have developer-related questions, there is a forum dedicated to that as well: Developer Forums
First off, you simply cd to the source dir, wherever it may be - in my case ~/Downloads/source/ - and during the install process, everything will be installed in its proper dir, right?
Yes. Hopefully the project you want to install follows standard conventions. If so, you can do "./configure", then "make", and finally "sudo make install" to install the software into "/usr/local".
How do you know which compiler to use? There seem to be several: make, gmake, gcc, g++, etc...
The make file will figure that stuff out.
Once you do figure out which compiler to run, the process is supposed to go like this, right?
./configure
make (or whatever)
make install
Yes, with the addition of "sudo" before "make install" because "/usr/local" is owned by root.
But this doesn't always work for me. For instance, I'm trying to compile 'arm', but it doesn't seem to have a 'configure' script.
$ ls ~/Downloads/arm

arm? You mean "arm (anonymizing relay monitor) - Terminal status monitor for Tor relays." You really don't want to be messing with that stuff. The only people involved with Tor that are trustworthy are US Navy intelligence who have their own uses for it. If you don't understand it as well as they do, best stay away.

Question about PL/SQL Function in report

Hi all. I have a (basic) question about using a PL/SQL function in a report. In my report page I have an item (PL/SQL function) that has the following syntax:
return username from t1
where username like 'Le%'
I reference this item in an email process. Ideally this function would return all usernames that begin with 'Le' in the drafted email; however, its not looping so I'm only getting a return on the first name.
I have a few books on PL/SQL but I'm not exactly sure where to start - I imagine there is a loop process I need to integrate into the function but, like I said, I'm not sure.
I would have posted this to the PL/SQL forum but also wanted some feedback on whether or not using this method is the best way forward. Essentially I have a table with usernames and just want to send email messages based on some simple logic.
Thanks!
Len

Hi Sergio,
First, it's an honor to have you reply to my post. Thanks!
To be more specific,
T1 is a table containing the results from a user security scan. Username is a column in this table containing user names. What I have done is create a page in HTML DB with the following elements:
1. An 'Item' containing the PL/SQL function that is hidden. The purpose of this Item is to generate information from T1 that meets the simple logic parameters - in this case, the user names that begin with "Le". I have called this Item P145_TT
2. A 'Process' containing references to HTMLDB_MAIL. The 'Process' looks similar to this:
HTMLDB_MAIL.SEND(
P_TO => '[email protected]',
P_FROM => 'Anon Email Account',
P_BODY => 'Note: This message was automatically generated. Do not attempt to reply to this email.
These are the users that begin with Le: '||:P145_TT||' ',
P_SUBJ => 'Summary');
3. A 'Button' to submit the process and (hopefully) send the message containing all users that adhere to the logic in the function.
4. If I use 'return username from t1...' I will get a username generated, but like I said previously, it only gives me the first and does not loop.

Questions about Macbook

I am about to go into my first year of college this July, and I've been looking for a laptop. I've used iMacs before a little bit, but I have a few questions about the Macbook Pro and Mac OS X 10.5. So if someone can help me that would be great.
First of all: How is the Macbook Pro overall as a laptop? Is it a pretty good one?
Secondly: How good is the back-up utility? (Time Machine) Is it pretty good? How big of an external hard drive would I need to back up everything?
Third question: How is the program Boot Camp? I'm planning on putting Windows XP Pro on the Mac using Boot Camp. How is compatibility? Also I've heard that if you make the partition for Windows less than 32 GB, the partitions would be able to "see" each other... does that mean Mac OS X can read FAT 32 drives? Would I be able to transfer files between the two OSs with that setup?
and lastly: Would Mac OS X be able to read my flash drive?
Thanks in advance everyone

I find it phenomenal, the best laptop I've used. OS X is a versatile and stable OS, and the hardware hasn't given me any trouble.
Secondly: How good is the back-up utility? (Time Machine) Is it pretty good? How big of an external hard drive would I need to back up everything?
It works great for me. You can't be nit-picky, so if you want a backup program with lots of settings there are plenty of options, but for those of us who just want something to fall back on when the HD goes kaput or we delete a file on accident, its perfect.
Third question: How is the program Boot Camp? I'm planning on putting Windows XP Pro on the Mac using Boot Camp. How is compatibility?

Would I be able to transfer files between the two OSs with that setup?
I haven't used it enough to answer the file sharing questions, but in my limited use it's been excellent, and many friends rave.
It's worth noting that when PC World was testing the fastest Windows Vista laptops, #1 was the MBP running Vista on BootCamp.
and lastly: Would Mac OS X be able to read my flash drive?
Yes. USB drives work great. The only thing, when you delete a file off a flash drive with default formatting, you'll only send it to a hidden "trashes" file. To permanently delete it off the stick, you'll need to push commandshiftdelete.
Hope that helps!

Here's a very basic question about 2 TB external drives and Time Machine.

Here's a very basic question about 2 TB external drives and Time Machine.
Ihave a Mac Pro with a .75 TB and 1 TB drive. It also has a 1 TB 2ndinternal drive. My current external drive is too small so I'll begetting a 1.5 TB or 2 TB drive.
Obviouslythe new larger 2 TB drive will backup everything on the Mac Prointernal drive with Time Machine. But there will be 1 TB of space leftover going to waste.
ShouldI partition the external drive so that the TM portion will be 1 TB andthe use the remaining extra partition for additional file backups withCarbon Copy?
Thanks for any insights.
I tried searching around on the new Apple discussion forum, but I find it much harder to use than the old forum I used to use.

The problem with terabyte drives is that that a 3 TB is about as big as you can get without going into RAID territory. Ideally, a Time Machine drive should be 3 times as large as all the drives you are backing up. So, if you have 2.75 TB of internal storage, you should have 8 TB of Time Machine space.
Of course, that is "should". If your TB drives are mostly empty, then you can get away with something 3 times the size of your used disk space. Just remember that you are pushing it. Linc is right about Time Machine needing space to work.
It is unlikely that you have regular churn on 2.75 TB of disk. I suggest identifying which drives and folders have the most activity and excluding those drives and directories that don't change much. It would be better to archive the data that doesn't change often and keep it out of Time Machine. Then you may be able to get away with a 2 TB Time Machine drive.

Some question about 9iAs R1.2.2 & R2, need your help:

Some question about 9iAs R1.2.2 & R2, need your help:
Since 2000, we has used 9iAS Core (R1.2.2) to publish our website. The platform is Suns Solaris (SPARC). The database is Oracle 8i. But there are so many questions:
1. The Web Cache cant be installed well
2. The web pages use JSP to query database with SQL show errors when we refresh the page a few times. The error will disappear after restarting the 9iAS or refreshing the page again. On the other hand, the same pages dont show error on resin. The error is java.sql.SQLException : Closed Connection: next. I supposed that the connection of database has some hidden troubles, but I can find it, could you give me some advice.
Now I have installed 9iAS R2, But when I visited the manage page, I found that a password is needed to visit the web cache manage page. I dont think I have set the password, and then I cant control the web cache. I want to know is a default password occurred? If not, what is the password.

The default password for Web Cache is: administrator

Question about Page Builder behavior - how to get a "please wait message" ?

Hi all together,
I got a question about Portal Framework / Page Buider handling iView Integration.
We are working with a lot of App Integrator iViews and often the pages includes with app integrator are loading longer than the rest of the portal. So there is the idea to put in a "please wait while loading message" for the enduser.
I analysed the html code, the page builder is generating and foud out 3 diffrent approaches how the page buider is rendering the IFRAME with the integrated application configured with an app integrator iView.
My question is how can I influence this behavior to put a "please wait while loading message"?
Different types of iView integration in the client I have seen:
a) direct loading of the content in the IFRAME (<iframe id="" ... scr="/mysource">)
b) Filling the iframe with 'about:blank' and loading the content later by filling a form with JS
( <iframe id="" .... scr="about:blank">and after the iframe <form id="" action="mysource" ...>
c) Filling the iframe with a html file from the portal layout and loading the content later by filling a form with JS (similar to b)
( <iframe id=""" ....scr="/irj/portalapps/com.sap.test.mylayout/html/blank.html>
I checked that variant b) is getting generated when loading a page with different components on the side (not only the app integrator iview) and variant c) is generated when just one app integrator iView is positioned (no portal page).
Goal: To get the "please wait picture" I want to know how to get variant c) in cases of different elements on one page
So I would be able to put this picture on the HTML-Page in the Portal layout (blank.html)
Hope, someone with a deep portal / page builder know-how can help me out!
Another way: Does anybody knows another way how to put a "please wait message" while app integrator application is not loaded yet?
Thanks in Advance and kind regards,
Jens

Hi Jens,
there are several reasons why you don't get the loading animation:
Web Dynpro ABAP: https://service.sap.com/sap/support/notes/1432358 -> missing configuration
Wrong height size for iView: https://service.sap.com/sap/support/notes/1358494 -> alter configuration of the iFrame height (loading animation gets displayed, but is hidden)
FPN, BSP, BEx: https://service.sap.com/sap/support/notes/1290995 -> AI isn't showing the animation because of performance considerations. I guess that is your case. Depending on your portal version this is a simple service configuration or involves some customization.

Question about printing by page count

Hi
I'm new to this and I have a question about printing our invoices by page count.
We generate our invoice using Crystal 2008 we have invoices that can range from a single page to as many as 6 pages. I would like Crystal to preview/print the reports in order of how many pages are in the report. Example: print all single page invoices first then all invoices that are 2 pages and so on. Is this possible?
Thank you in advance

Hi Ido,
Thanks for your input. This is more or less what Carl was suggesting yesterday and I gave it a lot of thinking. The problem here is that I cannot go with "good enough resolution" - I need perfect resolution.
The reason for this apparently silly requirement (why would one sort a bunch of invoices by number of pages instead of Customer Number, as long as they end up in an envelope anyway?) is the proposed purchase of a folding/stuffing machine which could do very fast what now takes one person 4 days to achieve.
One type of machine comes with three settings - fold/stuff 1, 2 or 3-page statements. You need to have three stacks with all the statements that have 1, 2 and 3 pages. The ones with more pages will have to be folded manually, but there are only about two dozen clients that give us that much business. You feed the machine one stack at a time and set it to process the respective number of pages. Any statement that falls accidentally in the other stack will either cause the whole rest of the stack to be mixed up, which is very bad, or cause one customer to receive his invoice and someone else's, which is just embarrassing. I cannot afford any of these scenarios.
Given that the statement contains variable-length (and depth) messages that vary by month and by profit center, and it could also contain one or more groups of details, each with its own header, it is very risky to try to come up with magic numbers attempting to estimate the number of pages based on the number of detail lines. Someone will still have to eyeball very carefully the initial stack of statements in the areas where the number of pages increases by one and make sure that ordering by number of detail lines did not mix, for example, one report with two pages among two reports with one page. Of course, this increased scrutiny will be necessary only around the areas where the page number transitions from 1->2, 2->3 and 3->4, which is much better than trying to order by number of pages all 1500 statements, but still depends on one's manual intervention and focus and, as a result, makes me pretty uncomfortable.
I have taken a look at the "Group Sort Expert". If you select the "All" option (all groups) and you had some kind of summary value then you could sort the report by that value. The idea was to create a hidden Average field over the TotalPageCount runtime variable (which will always equal the TotalPageCount for that customer, since it's the same for all the pages in that group) and use that summary field in the "Group Sort Expert", which would have solved the problem elegantly. Unfortunately, there is no way to create a summary field over a runtime variable. I even created a formula that just returns the TotalPageCount, but that formula did not show up in the list of fields available for summarization (while other formulas did).
It looks like the reporting engine does not allow this type of "late-sorting". I wonder if it is possible at all, because in effect this would require the engine to execute an additional pass: first it should somehow generate the whole report grouped by Customer Number so it knows how many pages are in each group, then it should sort by the number of pages and only after that it could render the report. I'm not sure the engine can do this additional pass.
I would be very curious to hear about the other (more complex) ideas you mentioned. For example, I have seen (in Crystal 2008) a checkbox allowing "sorting by a formula". I don't know how to write a formula used in sorting, but the basic question in the paragraph above still stands: does the engine even support such a feature?
Thanks again.

A question about Enumeration()

i am a beginner in java,resently i met a question about Enumeration(),and i hope someone can help me.
my question is that in the package of java.util there is an interface called Enumeration and there are two method hasMoreElements()��nextElemen() in it.
but in general we do not realize them before we use them.for example:
first we defined a new class Vector
Vector myVector = new Vector();
then when after we add some objects to it,we can do like this:
Enumeration e = myVectior.elements();
e.nextElemen();
i want to know where the method nextElemen is realized? incording to java's grammar,it is impossible to be realized in Enumeration for it is an interface,but
both class Vector and the my own class do not realize it too.so i am confused.

The class that implements the Enumeration returned by elements is hidden in the Vector class implementation. In fact, the class is anonymous. Here's the code from java.util.Vector (JDK 1.4).
   public Enumeration elements() {
        return new Enumeration() {
            int count = 0;
            public boolean hasMoreElements() {
                return count < elementCount;
            public Object nextElement() {
                synchronized (Vector.this) {
                    if (count < elementCount) {
                        return elementData[count++];
                throw new NoSuchElementException("Vector Enumeration");
    }

Question about parsing parameters through url

Hello,
I have some questions about parsing parameters through a url.
What I want to build is a page with some text fields and maybe one drop down list. After user enter values into the text fields and select one option in the drop down list, then press the submit button, a report will be opened, which according to the parameters parsed.
These were what I have done:
1. create a blank page and a region
2. create one text field in the region, the name is FIRSTNAME
3. create one hidden items FN, of which the source value is item FIRSTNAME
4. create a process. the type is "Set Preference to value of Item" which set PN with the value of FIRSTNAME when the page submitted
5. create a button "Submit Page and Redirect to URL", in the URL I entered:
http://dianti.local.net:9704/xmlpserver/~shichao/GuestFolder/orderdetail/orderdetail.xdo?_xpf=&_xpt=0&_xdo=%2F~shichao%2FGuestFolder%2Forderdetail%2Forderdetail.xdo&FIRSTNAME=&FN.&_xt=orderdetail&_xf=pdf&_xmode=4
My problem is: it seems working for the first time after I entered a value in the FIRSTNAME text field and press submit button, but when I come back to the page (the report was opened in the same page, wondering how to open it in a new window?), the value is saved in the text field and after I enter another value and submit the page again. It still parse the old value to the report. The value of the parameter doesn't change.
What's the reason? and is this the correct way to build what I want?
Thank you in advance.
Best Regards,
Shichao

Hi Scott,
Thank you again for the help.
But this didn't answer my question exactly. I have tested what you created and the problem remains. When I first time enter a value in the text field and press the button, it goes to page 2, but the parameter didn't parsed. When I go back to page 1 and then click the button again. After that I can see the value I parsed on page 2. Same thing happens when I try to enter a new value. So which means the button has to been pressed twice to parse the parameter.
Due to the limitation of my knowledge of Apex. I don't know how to fix it. Could you please help me again and hope you understand what the problem is. Thank you very much.

A simple question about performance!

Hi! I have a simple question about performance. Suppouse that you have a servlet or a class with DB access, and you need to use a value several times in that page. What is best, to assign the value from say, a resultset or a request.getParameter() to a variable or to call the resultset or the request every time you need to retrieve that value? Which option uses less memory, which is faster, etc.?
Hoping the best fou u

If you need more values from a db, the best is to open some connections (connection pool) and use the for accessing the db.
To get the data only once, open the connection, get the data, store the data whereever you want: variable (class), hidden control (if you want to send from one page to another by request) and close the connection as quicky as possible.
The advantage of the first method is that the most time consuming activity (connections opening) is done only once.
