Missing string problem

So I have this piece of code to save rows of data into a text file. The problem I'm having is that some times I am missing one of the data sets from the text file. It's always the same (first column) I say about .1% of the time.
Maybe it's just me but I really can't see why the first string would be missing. As far as I know the double going into Number to String can never be empty, right ? so the string shouldn't be empty either. I really don't see why or where the string goes missing. Maybe I'm not seeing something...
To clirify all the other data out of the concatenate string is there except the first string, where this string goes missing I really don't know. Any input is appreciated.
This is in LabVIEW 2010 by the way.
Here's how the data comes out on the file:

So here's the queue, I had to make some changes to it so I could post it but nothing related to the file management.
Basically these are the commands I send to it during a test:
1) DCE.Initialize (only at application initialization)
2) DCE.Initialize.RawFile (this comes from a GUI queue)
3) DCE.Start.SaveData (from GUI queue)
4) DCE.Process.DataToFile (from a DAQ loop that is always running and passes the Raw Data cluster)
5) DCE.Stop.SaveData (from GUI queue)
6) DCE.Close.File (from GUI queue)
Notes:
- No other queues send messages to this queue other than the GUI and DAQ loop.
- I did monitor the queue and there is never a backup of unprocessed elements.
- Not sure if it matters but so far this has only happened when running as an executable.
- Like I mentioned before this only happens in about .1% of the data sets.
Thanks

Help needed with missing data problem in CRVS2010

We recently upgraded the reporting engine in our product to use Crystal Reports for Visual Studio 2010 (previously engine was CR9). Our quote report, which has numerous subreports and lots of conditional formatting, started losing data when a quote took more than a single page to be printed. We knew the SQL results included the data, but the report was not printing those lines at all or sometimes printing a partial line. In addition, the running total on the report would exclude the lines that were being missed on the next page. In one example submitted by a customer, 3 lines were skipped between pages.
I think I have identified two potential issues that document the possibility of data not being included in the report.
The first potential issue is an issue with the "suppress blank section" option being checked. This issue is supposedly fixed with ADAPT01483793, being released someday with service pack 2 for CRVS2010.
The second potential issue is using shared variables. This issue is supposedly fixed with ADAPT01484308, also targeted for SP2.
Our quote report does not explicitly use shared variables with any of the subreports, but it does have several subreports, each in its own section that has the "supress blank section" option checked. We have other reports that use this feature, as well, and they are not exhibiting the problem.
One different thing about the quote report is that it has a section with multiple suppression options selected. The section has a conditional suppression formula, which controls whether the section is included at all within the report. The section also has the suppress blank section option selected. There are multiple fields within the report that are each conditionally suppressed. In theory, the section's suppress formula could evaluate to true, yet all of the fields within the section are suppressed (due to null values), and then the "suppress blank section" option would kick in.
The missing data only seems to happen when the section is not being suppressed, and at least one of the fields is being included in the report. If I clear the "suppress blank section" check box, and change the section formula to also include the rules applied to the fields in the section, the missing data problem seems to be resolved.
Is this related to ADAPT01483793? Will it be fixed in service pack 2?
If more details are needed, I would be happy to provide a sample report with stored data.

Hi Don,
Have a look at the Record Selection formula in CR Designer ( stand alone ) and when exported to RPT format opening that report in the Designer also.
There's been a few issues with => logic in the record selection formula. It could be you are running into this problem. Look for NOT inserted into your selection formula.
Oh and SP2 is coming out shortly so it may resolve the issue. But if you want you could purchase a support, or if you have a support contract then create a case in SMP and get a rep to work with you to debug the issue.
If you have not try the Trial Version of CR 2011, put it on a VM-ware image or Test PC so you don't corrupt anything for production and have a look at and test it in that designer also. If you purchase a case and it is a bug then you'll get a credit back for the case.

The missing library problem.

I understand that there's already a lot of threads about the sudden disappearance of iTunes libraries, however I'm typing this up because I'd like to point out in a bit more detail what I'm seeing happening to my computer, and maybe have a collective of what's going on. This issue has happened to me five times in the last two months since I've updated to iTunes 11. After searching on google I know the missing library problem has existed since the early 2000s; why this glitch has yet to be fixed 13 years later is beyond me. I have personally never had this problem until updating to 11, and seeing the many other threads on here this appears to me to be an issue with this version of the software more than it has been in previous versions.
Before I continue, I have tried the following to fix it:
Simply readded my whole library. It was only wiped again a few weeks later.
Completely uninstalled and reinstalled iTunes. That didn't work either, so it's not just an updating problem.
What I haven't tried
Changing where on my computer iTunes is installed. I have no idea where on the computer might be better or if it will change anything. I have iTunes installed on its default location on my local C: disk.
Importing the music directly from my iPod into iTunes. Can this be done? If so, how? Not everything on my iTunes is a store purchase, most of it is imported CDs and also amazon purchases too. So I don't know if the transfer purchases option works. While this wouldn't fix this current issue, I would like to know how to do this if possible since it would just be a quick fix whenever this happens.
What is happening:
So each time this has happened, what occurs is that like many other people, one day I open my iTunes and everything is in order. Then the next, for no reason, all of my libraries are gone but the music is still on my computer, organized in their files the way iTunes had them done so upon importing. I can't use the .itl files in the "previous libraries" folder because they have also been re-written. Upon opening them, even if their last save was on a day I know everything was in working order, opening them does nothing but give me the same blank default page.
What isn't mentioned in a lot of the posts regarding this issue, is the sudden crop of temporary files in the iTunes folder.
The ones that have cropped up for me personally are the following:
iT 1.tmp
iT 2.tmp
iT 3.tmp
iT 4.tmp
Temp file 1.tmp
Temp file 2. tmp
Those were not there the last time I used iTunes, and they're never there on the days I've used it before and it has worked correctly. However every time my library is wiped, these files suddenly appear without fail, every time. I can't open them, I can't do anything with them except delete them. I believe I remember reading somewhere that this might be an issue regarding with how the program is saving the progress of your library changing, and that the temp files are there until it can "officially" save what has happened to your library. While I didn't change anything in my library in the last couple of weeks, I'm assuming this also counts things like play count.
My own personal opinion
Seeing just how many threads with this issue are popping up, this leads me to believe that this isn't just a problem with my personal computer or my personal install of iTunes 11. These temp files also lead me to believe that as well. In other words, whatever glitch has existed with iTunes since the early 2000s is for some reason running rampant in version 11.
TL;DR:
Please developers, actually look at this library glitch within the program itself. It can't just be an individual user's problem because way too many people are experiencing it.

No worries. You've probably run into one the other threads I've posted to but I'll add my thoughts here anyway...
Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. Note that in iTunes 11 an "empty" library may show your past purchases with links to stream or download them.
In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
Alternatively, depending on exactly when and why the library went missing, there may be a more recent .tmp file in the main iTunes folder that can be copied and renamed as iTunes Library.itl to restore the library to an earlier state. Look for a recent .tmp file that is similar in size to the .itl files in the Previous iTunes Libraries folder. If it has happened repeatedly you may want the earliest such file generated since the last iTunes upgrade.
If applicable, see iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!
Should you be in the unfortunate position where you are no longer able to access your original library, or a backup of it, then see Recover your iTunes library from your iPod or iOS device.
I've noticed more of these missing library posts of late and a common factor to most since I started asking is AVG Anti-Virus. It seems in some cases it might be at least part of the reason why the library file disappears. Try excluding the iTunes folder from any AV scanning process.

Missing Pictures problem

Missing Pictures problem, I work with Adobe Illustrator CS2 at work & CS3 at home but i have the problem with both. I have a problem with missing pictures from time to time after saving the file & moving the image from original location. I know you have to link the images/files and leave then where the are or you can embeded them. So in my option box i un select the link the files box & i still get the missing files problem, when re-opening the AI file.
Does anybody know why? Or what I can do to avoid this?
Thanks

Could you expand on that a bit please... the "make aliases of your pictures", i mean...

Another, and probably much easier way, is just to use Ctrl + Y... and use subsets of the selections in the SUIM reports.
But I can well understand the temptation to use tables or at least double-check the SUIM output against them.
The bugger with tables is that you can easy make the same mistakes or more than the SUIM reports do, or use old obsolete tables, or incorrect logic when interpreting single fields of the user tables.
Personally, I would normally check the exits first. Developers don't always raise self-explanatory messages...

Missing string(reports_security_desc) language(us) domain (wwc) sub_domain (sec)

When I go in to administer Report Security I see "Missing string(reports_security_desc) language(us) domain (wwc) sub_domain (sec)" where I should see "Report Security" portal.
I noticed when running rwwwvins.sql the following errors:
grant all on wwv_rw_adm_tst to rw_administrator

I thought RW_ADMINISTRATOR was a group not a role? Why is this erroring out?
Please any help on this?

I did the uninstall and reinstall from where Oracle 9iAS server and patch 3a was applied and then I had to do the sqlldr script seperate. Now the "Oracle Reports Security" appears under the Administration page.

Verizon is releasing another update tommorow: ED05 did not fix the miss call problem

I got two voice mails today that did not show as missed calls . I call Verizon technical support and ask to speak to a manager. He told me that several people are still having miss call problems and to expect a new update august 1 which is tommorow. I told him this is the last straw , if this new update doesn't work for me, they are going to have to give me a different phone or release me from my contract. This is so frustrating.

I called Verizon 2nd level tech support and they assured me there is NO ED06 update's said they haven't even finished rolling out ED05 yet. I think they just told you that to get you off the phone. I also have a Fascinate and have had problems and can't get them to replace my phone with a different device. I want the Droid Charge since it is the only other one that has the AMOLED screen that I originally chose the Fascinate for . They had a program that ended on July 28th the day that ED05 rolled out. They offered the Droidx, the Incredible 2, and the Droid Charge to replace the Fascinates that were having trouble. I had called to report my issues during this replacement program but was not told that it was going on and now they won't give me the Droid Charge because it has expired. I think since there are STILL issues-they need to bring this program back and allow us to get a different phone. I have been a customer of Verizon for 10 years and have 7 lines so I am REALLY disappointed that they can't work with me (or other customers ) especially since it is not something we did to the phone. It is a problem with either Verizon or Samsung. I don't know where to go from here but maybe if they hear enough from others that didn't have any success with ED05 they will start to replace them. I will probably go to a higher level to voice my concern. Let me know if anyone has any success getting a new device especially the Droid Charge.

1603 install - missing string

So I'm struggling with a 1603 when I try to install 7.1.1 and posted earlier about that problem. Here's maybe another clue:
I found an old iTunes install CD that I got with an iPod mid-2006.
When I try to install from the disk I get a
String PRODUCT_NAME was not found in string table
pop up message, then the install finally fails with another popup:
Unhandled Exception
Error Number: 0x80040706,
Descrption: Object Reference not set
Setup will now terminate
Any ideas anyone?
thx .. jeff

good-o.
the InstallShield engine upgrade might help also with the 1603 on installing the 7.1.1.5.
although the iTunes 7.0.x and 7.1.x installers are not InstallShield-based, previous versions (like the one you're getting the string errors on) were. so a missing or damaged InstallShield version 11 engine can compromise a 7.0.x or 7.1.x install by playing silly buggers with the new installer's attempt to uninstall the older (non-version-7) version of iTunes.
(thinking that's plausible as a cause for your 1603, because the 7.1.x and 7.0.x installers typically don't return that error message number ... they just say "fatal error" instead. so the prime candidate for what's returning it would be the previous non-version-7 installation of iTunes.)

Null String and Empty String problem

Hello everyone,
since i am totally new in JSP, i am getting problem in handling strings.
Suppose i have a variable users = ""; then
I want to ask when to use:
if (users.equals(""))
and
if(users == "")
in my code, variable users has value "regional" for regional users.
and i am checking this code as:
if (users.equals{"regional")) {
out.print ("I am inside code");
at that time, the code is throwing error (run time error)
and when i changed the code as:
if (users == "regional") {
out.print ("I am inside code");
this time, the code is not generating error but the part message "I am inside code " is not displaying. The code do not inserts inside the if condition
I hope u understand my problem. Can anybody help me out with this.

This has basically nothing to do with JSP, but with basic Java knowledge.
When using the '==' operator to compare Objects (yes, String is actually a subclass of Object), then it will look if they are of the same reference. Using the '==' operator to compare primitive datatypes (int, boolean, char, etc) will look if they have the same value.
That is why the Object class has the equals() method to give the ability compare with another objects. And you can only invoke it when the Object is actually instantiated. So if it is not null.
if (string != null && string.equals("somevalue")) {
// or
if ("somevalue".equals(string)) {
}should work.
Edit rym82: this will not throw a NPE, but an ordinary compilation error ;)

I am not sure about the cell style as it looks like you are doing it right. For the null or blank cells it looks like you are only checking for null not "".

Photos are Missing messages Problem constantly showing up

I screwed up. I had iPhoto link to my photos on my hard drive rather then importing/embedding them into the iPhoto library but then I believe I reorganized all my original folders (merging, file renaming etc.). So that is one reason I am getting missing photo messages. I thought iPhoto would automatically track the originals but that was probably a wrong assumption.
Not sure how to find/mark which photos are all missing and reconnect them to where they are located now and how to fix it so I don't get the messages. I have to go through around 300 "Can't Find Photo dialogs" if I accidently click on a orphaned photo (thumbnail without a photo).
I have made some changes to some photos in iPhoto and I would prefer not to lose those changes. I don't want to lose my Current Albums and Books and Slideshows etc. But I'm guessing I need to backup and re-import all my photos again in a new library but that cause me to lose my meta-data (Albums, Phtot Changes, Slideshows etc.)
I tried rebuilding the library but it still prompted me with the "Can't Find Photo Questions" and never really solved the problem.
The reason I didn't embed was I wanted other application to be able access my photos without having to go through the trouble of exporting them first, and also to save space. But I saw a 1TB drive for $370 so maybe space shouldn't be the issue anymore and I have iPhoto Library Manager so there should be no problem with having my library on a different drive then the pictures folder on the HD.
It would be sure nice if most Apple applications (Final Cut Studio for example)could select from the iPhoto or Arpeture (I was thinking of buying) library.
Anyway any suggestion on how to fix my orphaned photos without losing all my changes?

I just noticed it as well out of the blue. Could have sworn that it always worked and suddenly stopped without any updates or anything.
The "right click-paste" function of a jpeg is not working in apple mail. You can drag and drop a picture into the email, or "right click-copy image" and "command -v" it into the body of the email and see the picture but "right click-paste" only produces the "box with the blue question mark". This is only happening in mail as far as I know, in .pages "right click-paste" works just fine.

Host String Problem

Hi everyone, i searched the forum and found same problem with me but i did not work for me. The problem is i cannot connect my sql plus. i enter my username and password then it asks me gor host string but when i type it and enter "ok" it says "TNS Listener does not currentl know of service requested in connect descriptor. i looked at my tnsnames.ora file and is exactly like this.
# tnsnames.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
CSE348 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Canavar)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = cse348)
So what shoul i type to connect sql plus?

Given the tnsnames.ora content, the following needs to be entered for sqlplus in order to have it use that connection string in the file:
sqlplus scott/tiger@CSE348As you have not qualified the alias with a domain, it will default to "+.world+" as far as I recall. If the default domain in your local sqlnet.ora differs, than that default will be used to find alias CSE348 in the local tnanmes.ora file. So make sure that you do not mix default and explicit domain names. Rather specify a default domain in sqlnet.ora and use the same domain for defining full qualified domain name TNS aliases in tnsnames.ora.
As for the error - the Listener receives a connection request for a service called cse348 - and no such service has registered with it. You can check the known services of the listener using the "+lsnrctl services+" command on the server.
Often in this case, it is easier to request a specific database instance using its system identifier, or SID. In which case you can change your connection string for the alias to use a SID as follows:
CSE348 =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = Canavar)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SID = cse348)
)This assumes that the SID is cse348. The default SID is for example orcl. SIDs like dev and prod are also often used.

IE 10 blank new tab and missing favourites problem only when requiring a proxy for first page visit

We are having a very strange situation with one (only) of our 64bit 2008r2 remote desktop session host servers. The problem we are having is that when any new tab or window is opened it must first open a page that is in the
internet options -> connections ->LAN settings -> Advanced -> Exception. Do not use proxy server for addresses beginning with
Area. OR ELSE....
The entire contents of the favourites menu below "Organize favourites" is missing, though the favourites explorer bar, and tool bar display the links, but they cannot be opened in the current tab and will not create a new tab when you click open
in new tab. HOWEVER, this problem is instantly resolved if you manually type into the address bar and visit a site that is in the proxy exception list. Then that tab starts to function normally, the favourites menu is populated and works, and so
does the favourites explorer bar, and toolbar, and other websites can be visited.
This is extremely problematic. Looking at the proxy server logs, when the problem is happening no attempt is made at contacting the proxy server.
Ways we've encountered this problem
If the user has the option set that a new tab opens the 'new tab page' then any new tab experiences the problem.
If the browser is set to open the user's home page(s) then any of the home pages that are not in the exception list may or may not open successfully. But again any of them that opened a page that was not in the proxy exception list will experience
the problem
when a user tries to click on a website link from an email or document that is not in the proxy exception list, as this opens a new window or tab and it is just blank.
when a website not in the exception list tries to open a new window/tab
This problem is happening for all users on that RD session host server, including domain admins, except for THE domain/enterprise administrator. Our other 2008r2 64bit RD session host servers and windows 7 machines with the same version of IE
installed on it does not have this problem.
We have tried deleting all IE data, resetting IE, re-registering the ieproxy.dll with the regserv32 command and the problem continues.
Our proxy settings for each user is coming from the group policy setting of 'computer config -> policies -> Administrative Templates -> Windows Components -> Internet Explorer -> Make proxy settings per-machine = enabled'
and THE domain administrator choosing to enable the proxy server and disable automatic proxy detection.

Hi,
Since you have tried many methods like deleting all IE data, resetting IE, and it works well on other Windows 7 machines, the problem might be some clients didn’t respond to the group policy.
Try to update the group policy with this command at the clients ”gpupdate /force”.
And check whether the client is infected with virus, some virus might cause this issue too.
