Need Help with strange X-Fi Fatal1ty BUG !
Hi all,
My specs are as follows:
AMD FX-55
2GB Corsair DDR550
Gigabyte GA-K8NXP-SLI mobo
2x XFX 7800GTX Extreme
X-Fi Fatalty (5. config, DR2.7.4)
My X-Fi Fatalty has a very strange bug.
Every time I quit F.E.A.R (v.3), my PC freezes and a hard reset is required.
Game starts fine. And the in-game sound is unbelievable. Everything works fine until I exit F.E.A.R.
Even stranger, after the hard reset my X-Fi reverts to a 2. config and a Creative file (DLLML.exe) uses 99% CPU resources and brings my PC to a crawl. I use CTL-ALT-DEL to end it, then after the next restart the same happens again.
Only a FULL X-Fi driver re-install fixes the problem. But when I exit FEAR again, the same happens again.
I tried switching OFF CMSS, HW mixing, EAX2.0 and EAX advance HD but still the PC crashes when I exit FEAR.
If I run FEAR to the title menu, then exit, its fine. But if a level loads then I exit the game, It crashes.
Any feed back would be appreciated.
Thanx

Ok, I found a way to prevent my PC from crashing.
Play FEAR, save game then use ALT-TAB to exit to desktop. Then use CTL-ALT-DEL to close FEAR.
All works fine.

Hi All,
While developing my JNI native methods, I have run across the following error:
Unexpected Signal : 11 occurred at PC=0x40301743
Function=(null)+0x40301743
Library=/usr/java/j2sdk1.4.2_02/jre/lib/i386/client/libjvm.so
NOTE: We are unable to locate the function name symbol for the error
just occurred. Please refer to release documentation for possible
reason and solutions.
Current Java thread:

Has anyone seen this before? What does it mean? It not in any of my native methods, but somehow I know they must be causing it.Yes, but ..
The strange part is that usually when that happens I get a signal 11 or some such thing in the method where the problem is..
In this case, it seems to die a lot later, inside of some other classes.
The only explanation I have is "memory trampling".. :( -
Need help with a currently "in-use" form we want to switch to Adobes hosting service
Hi, I am in desperate need of help with some issues concerning several forms which we currently use a paid third party (not Adobe) to host and "re-distribute through email"...Somehow I got charged $14.95 for YOUR service, (signed up for a trial, but never used it)..and now I am paying for a year of use of the similar service which Adobe is in control of. I might want to port my form distribution through Adobe in the hopes of reducing the errors, problems and hassles my customers are experiencing when some of them push our "submit button". (and I guess I am familiar with these somewhat from reading what IS available in here, and I also know that, Adobe is working to alleviate some of these " submit" issues, so let's don't start by going backwards, here) I need solutions now for my issues or I can leave it as is, If Adobe's solution will be no better for my end users...
We used FormsCentral to code these forms and it works for the most part (if the end-user can co-operate, and thats iffy, sometimes), but I need help with how to make it go through your servers (and not the third party folks we use now), Not being cruel or racist here, but your over the phone "support techs" are about horrible & I cannot understand them or work with any of them, so I would definitely need someone who speaks English and can understand the nuances of programming these forms, to please contact me back. (Sorry, but both those attributes will be required to be able to help me, so, no "newbie-interns" or first week trainees are gonna cut it).... If you have anyone who fits the bill on those items and would be willing to help us, please contact me back at your earliest convenience. If we have to communicate here, I will do that & I can submit whatever we need to & to whoever we need to.
I need to get this right and working for the majority of my users and on any platform and OS.
You may certainly call me to talk about this, and I have given my number numerous times to your (expletive deleted) time wasting - recording message thingy. So, If it's not available look it up under [email protected]
(and you will probably get right to me, unlike my and I'm sure most other folks', "Adobe phone-in experiences")
Thank You,

Phenix City, Alabama 36869Well, thanks for writing back...just so you know...I started using Adobe products in 1987, ...yeah...back then...like Illustrator 1 & 9" B&W Macs ...John Warnock's Helvetica's....stuff like that...8.5 x 11 LaserWriters...all that good stuff...I still have some of it working on a mac...much of it was stuff I bought. some stuff I did not...I'm not a big fan of this "cloud" thing Adobe has foisted upon the creatives of the world...which I'm sure you can tell...but the functionality and usefulness of your software can not be disputed, so feel free to do whatever we will continue to pay for, ...I am very impressed with CC PS on the 64 bit PC and perhaps I will end up paying you the stipend that you demand for the other services.
So I guess that brings us to our problem.. a few years back and at the height of the recession and near bankruptcy myself, I was damn lucky and hit on something and began a small arts and crafts supply service to sell my products online to a very "niche market" ...I had a unique product and still sell that product (plus others) online...My website is www.vinylcouture.com...Strange? Yes...but there is a market it seems, for everything now, and this is the market I service...Catagorically, these are 99%+ women that use these "adhesive, sticky backed vinyl products" to make different "craft items" that are just way too various and numerous to go into... generally older women, women who are computer illiterate for the most part...and all this is irrelevant to my problem, but I want you to have every bit of background on this and especially the demographic we are dealing with, so we can get right to the meat of the problem.
OK...So about two years ago, I decided to offer a "plain sheet" product of a plain colored "stick back" vinyl... it is available in multiple quantities of packs ( like 5 pieces, 10 pieces, 15 pieces, in a packi & so on)...and if you are still on my site.. go to any "GO RIGHT TO OUR ORDER PAGE" button, scroll down a little...and then to the "PLAIN VINYL" section...you will see the Weebly website order process.) You can back out from here, I think,..but, anyway this product is available in 63 colors + or - a few. So then the problem is, how do they select their individual colors within that (whatever) pack?... .
So my initial idea was to enable a "selection form" for these "colors" that would be transmitted to me via email as 'part" of the "order process".. We tried getting our customers to submit a " a list" ( something my competitiors still do, lol, poor bastards)......but that..is just unbelievable..I can't even begin to tell you what a freakin' nightmare that was...these people cannot even count to 10, much less any higher... figuring out what colors to list and send me... well, lets just say, it wasn't working......I had to figure out a better way...Something had to be done.
So after thinking this all out, and yeah...due to my total ignorance, i figured that we could make a form with Live Cycle Designer (Now Forms Central)...(back then something that was bundled with Adobe Acrobat Pro), I believe, and thats what this thing was authored in... and it would be all good...LOL!
Well not so simple...as you well know, Adobe Acrobat would NOT LET YOU EMAIL anything from itself.....it just wouldn't work (and I know why, and all that hooey), but not being one to take NO for answer,.I started looking for a way to make my little gizmo work.. So I found this company that said they can "hijack" (re-direct actually) the request to email, bypass the wah-wah, and re-transmit it to the proper parties.....for less than $100 a year, I think...its called http://pdf-fillableforms.com/.
A nice gentleman named Joseph Silva helped us program the thing to go to his servers and back out. Please dont hassle them...I need them...for now..it basically does work...try it...you should get back a copy of the form that you filled out...good luck however, if you're on MAC OSX or similar...
I have included a copy of both of our forms (and feel free to fill it out and play with it)...just put test somewhere on it...(and you must include YOUR email or it will balk)..they are supposed to be mostly identical, except one seems to be twice as large....generating a 1.7 meg file upon submission, while the other one only generates a 600K file or so...thats another issue for another day or maybe you can advise on that also...
OK so far so good......In our shop, once Grandma buys a 10 pack (or whatever), Only then she gets to the link on her receipt page ro the relevant "selection form" ,(this prevents "Filling and Sending" with "no order" and "no payment", another early problem we had)... which they can click on and it will usually download and open up on their device if all goes well...Then our little form is supposed to be fillable and is supposed to ADD UP all the quantities, so grandma knows how many she is buying and so forth right on the fly, and even while she changes her mind..., and IT'S LARGE so grandma can see it, and then it TOTALS it all up for them, ( cause remember, they can NOT add).., except there is a programming bug (mouse-click should be a mouse-up probably or something..) which makes you click in the blank spaces to get to a correct TOTAL...about 70-80% of our customers can enable all these features and usually the process completes without problems for them especially on PC's running Windows OS and Acrobat Reader X or XI...at least for most... Unfortunately it is still not the "seamless process" I would like or had envisioned for the other folks out there that do have trouble using our form.... Many folks report to us the following issues that we know of. First of all it takes too much time to load up...We know its HUGE...is there anyway that you can see, to streamline this thing? I would love for it to be more compact...this really helps on the phones and pads as I'm sure you well know.
Some just tell us,"it WON'T work"....I believe this is because they are totally out of it and dont even have Adobe Reader on their machine, & don't know how to get it ( yes, we provide the links).....or it's some ancient version....no one can stop this one...
It almost always generates some kind ( at least one time) of "error message" which we do warn them about..., telling one, basically that "Acrobat doesnt even like this happening at all, and it could be detrimental to ones computer files", blah-blah...(this freaks grandma out really bad)...& usually they end up not even trying to send it... and then I get calls that even you wouldn't believe...& If they DO nut up and push the Red "Submit Form" button, it will usually send the thing to us (and also back to them at the "required email address" they furnished on the form, thats what the folks at the "fillable forms place" do) so, if it's performing it's functions, why it is having to complain?. What are we doing wrong?....and how can I fix it?...Will re-compiling it or saving it as a newer version of "FormsCentral" correct any of these problems ?
Ok, so that should keep you busy for a minute and we can start out with those problems...but the next thing is, how can I take advantage of YOUR re-direct & hosting services?, And will it get rid of the error messages, and the slowness, and the iOS incompatibilities ? (amazingly, the last iOS Reader version worked almost OK.. but the newest version doesnt seem to work with my form on my iphone4) If it will enable any version of the iOS to send my form correctly and more transparently, then it might be worth the money...$14.95 a MONTH you say. hmmmmm...Better be good.
Another problem is, that I really don't need 5000 forms a month submitted. I think its like 70-100 or less....Got any plans for that? Maybe I'm just not BIG ENOUGH to use Adobe's services, however in this case, I really don't care whose I do use as long as the product works most correctly for my customers as well as us. Like I said, If I'm doing the best I can, I won't change anything, and still use the other third party, If Adobe has a better solution, then i'm all for that as well. In the meantime, Thanks for any help you can provide on this...

Need Help With File Matching Records
I need help with my file matching program.
Here is how it suppose to work: FileMatch class should contain methods to read oldmast.txt and trans.txt. When a match occurs (i.e., records with the same account number appear in both the master file and the transaction file), add the dollar amount in the transaction record to the current balance in the master record, and write the "newmast.txt" record. (Assume that purchases are indicated by positive amounts in the transaction file and payments by negative amounts.)
When there is a master record for a particular account, but no corresponding transaction record, merely write the master record to "newmast.txt". When there is a transaction record, but no corresponding master record, print to a log file the message "Unmatched transaction record for account number ..." (fill in the account number from the transaction record). The log file should be a text file named "log.txt".
Here is my following program code:

I am not sure what is wrong with my code above to make my results different from the correct results.
Much help is appreciated. Please help.From the output, it looks like one problem is just formatting -- apparently you're including a newline in log entries and not using tabs for the newmast output file.
As to why the numbers are off -- just from glancing over it, it appears that the problem is when you add multiple transaction values. Since account.combine() is so simple, I suspect that you're either adding creating transaction objects incorrectly or not creating them when you should be.
Create test input data that isolates a single case of this (e.g., just the Mary Smith case), and then running your program in a debugger or adding debugging code to the add/combine method, so you can see what's happening in detail.
Also I'd recommend reconsidering your design. It's a red flag if a class has a name with "Create" in it. Classes represent bundles of independant state and transformations on that state, not things to do. -

the arithmetic operations as well as at least five scientific operations of the
Math class.
-Your program must also have the ability to round a number and
truncate it.
-When you multiply by 2, you should not use the '*' operator to perform the
operation.
-Your program must also be able to reverse the sign of a number.

* Make use of helper classes where possible.
* Use the SDK to run your program."""
When the program starts, it asks the user for his/her name and surname. I got the program to ask the user again and again for his/her name and surname
when he/she doesn't insert anything or just press 'enter', but if the user enters a number for the name and surname part, the program continues.
Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??

What you could do is checking the input string for numbers. If it contains numbers, just reprompt for the Name.
AND you might want to ask yourself why the heck a calculator needs to know the users Name. -
Need help with almost completed plugin engine project
Hi all,
For a while now I have been working on a plugin engine. After a few iterations, the engine is similar to the Eclipse engine, in that plugins use extension points and extensions to allow contributions. Unlike the eclipse engine I have added the ability for plugins to fire events through the engine and other plugins can add listeners, all through the plugin.xml manifest. Dependencies are mostly handled automatically at plugin load time (when extensions get resolved to extension points, and listeners get resolved to events). For the case where a plugin needs to use classes from another plugin, dependencies are also allowed to be declared. Like the eclipse engine, activation of plugins occurs the first time a class is used within the plugin's classpath, OR a plugin can be activated after it is loaded.
What I need help with is testing, working on examples to provide with the engine project, and feedback/suggestions before we release the M1 build. I am asking for those that are interested in this type of work to volunteer to help where applicable and possible. I want to provide a solid plugin engine to the java community, one that is easy to use, works well, and is pretty effecient in terms of resource usage and performance.
Of particular interest to me right at the moment is dealing with multiple versions. As I see it, the engine will be used within an application and as such plugins would be distributed with a specific application version. The plugin version itself is more of a notification as to what version a plugin is, although I imagine it will help when updating at runtime as well.
Just a few other details of the engine. It handles (or will soon) dynamic load, unload and reload of plugins at runtime. Plugins can be distributed in an archive file format, we call .par (Plugin ARchive), with additional plugin filename extensions configurable at runtime. The plugins can be developed and deployed in an expanded directory format as they are in Eclipse as well, or in the archive format. In the archive format they do not need to be unzipped when deployed, and they can contain embeded jar/zip libraries. The engine handles finding and creating classes directly out of the .par file at runtime.
Multiple locations to find plugins are configurable before the engine starts, and even after it starts more could be added to allow additional locations to find plugins. URLs are supported, and soon the HTTP protocol will be supported so that plugins can be downloaded and installed at runtime.
The project can be found at www.sourceforge.net/projects/genpluginengine. If you would like to get involved and help out, please sign up on the dev mail list and send an email to introduce yourself to the rest of the members on the list.
I'll also add that I am working on a Swing UI Framework built entirely from plugins. It provides a ready-to-launce UI application that developers can simply add their plugins to, extending various extension points of the framework to have menu items, toolbar buttons, status bar access, help and preferences dialog additions, file i/o choosers, tons of open-source components ready to use (or extend to add on to), and like Eclipse, hopefully... draggable window frames that can be dropped on any other frame to form a tabbed frame of windows. Some of this is a ways off, some is getting there now. Presently you can add menu items that do allow plugin activation when first clicked, so plugins can be loaded but not activated until needed. The Preference dialog works but is not completed, and a plugin that adds a plugin control panel to view all loaded plugins, activate them, load/unload/reload, view extension points, extensions, dependencies, etc is partially completed. The point is, to allow a ready to run UI framework in Swing with an easy path for developers to quickly build applications with. If you are interested in this, when you join the mail list and introduce yourself, indicate that you are interested in this as well, as we need help with plugin development for it and would appreciate more help here too.
Look forward to some replies.Might I suggest setting up a project at a known project-site? I've seen your progress and questions posted here from time to time, but one of the drawbacks is that you have to fill each post with the entirity of your vision to explain what you're doing. That's a lot of text to read - and most folks will skip right over it.
On the other hand, a well-crafted, good-looking project web-site, with appropriate links and docs and vision statements, diagrams, etc. will have more likelyhood of attracting volunteers. java.net and sourceforge.net are likely spots to set up shop. In addition, you get CVS and bug-tracking systems, which can be quite valuable in such a large-scale project where there are lots of pieces. -
Need help with my usecase based on transient ViewObject
I am using 11.1.1.4.0 Jdev version. I need help with my usecase.Been trying it for 2 days but couldn't figure out the issue.
I have a transientVO . In this VO Rows will be populated programmatically. CountryId is an attribute of this VO. I have created a viewAccessor "CountriesVA" from Country VO of HR schema.
I have a LOV for the countryId which is based on this VA ,getting countries from CountryTable.
This is the model part which works fine.
Before the page load i have called a method to create a row for this transientVO.Once the row is created i can see the SOC in my page which i have created as below.
Now i want to insert a row in the transientVO if user selects a country and restrict duplicate entry . (As One row is already created 1st time there will be no rows created.after that rows will be inserted)
The issue is :: Suppose there are 2 countries. A & B .When user does the following actions :
Insert A . Done //as 1st entry
Insert B . Done //as 1st time entry
Insert A . duplicate not inserted
Insert B . getting inserted // the bug.

9.7.6 What You May Need to Know About Programmatic Row Set Iteration
The problem is solved ,the above links helped me solve the problem.
what i did is i have created a method in appmodule to iterate rows and all the method y operation bindings and my logic works fine ....
MY Advice to all Adf developers ,though i am not an expert but i can assure you to follow the above process for rowIteration.If you use the iterator binding in the manage bean to navigate the rows u'll face issues which are unexpected.
In AppModule :::::
public boolean createRow(String oldValue,String newValue){
System.err.println(oldValue+""+newValue);
ViewObjectImpl vo=getViewObj1();
boolean duplicate=false;
if(oldValue!=null){
RowSetIterator iter = vo.createRowSetIterator(null);
System.err.println("iterating rows ");
while (iter.hasNext()) {
Row r = iter.next();
System.err.println(iter.getRangeIndexOf(r)+" row is "+r.getAttribute("CountryId"));
if(r.getAttribute("CountryId").toString().equals(newValue)){
duplicate=true;
break;
// Do something with the current row.
// close secondary row set iterator
iter.closeRowSetIterator();
return duplicate;
In ManageBean :::::
public void countryIdVC(ValueChangeEvent valueChangeEvent) {
// Add event code here...
String oldValue=null;
System.err.println("Old Value"+valueChangeEvent.getOldValue());
setEL("#{bindings.CountryId.inputValue}", valueChangeEvent.getOldValue());
if(evaluateEL("#{bindings.CountryId.attributeValue}")!=null)
oldValue =evaluateEL("#{bindings.CountryId.attributeValue}").toString();
setEL("#{bindings.CountryId.inputValue}", valueChangeEvent.getNewValue());
String newValue=evaluateEL("#{bindings.CountryId.attributeValue}").toString();
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
//access the name of the iterator the table is bound to. Its "allDepartmentsIterator"
//in this sample
DCIteratorBinding dciter = (DCIteratorBinding) bindings.get("ViewObj1Iterator");
//access the underlying RowSetIterator
RowSetIterator rsi = dciter.getRowSetIterator();
if(oldValue!=null){
rsi.getCurrentRow().setAttribute("CountryId", oldValue);
OperationBinding operation = bindings.getOperationBinding("createRow");
operation.getParamsMap().put("oldValue", oldValue);
operation.getParamsMap().put("newValue", newValue);
if(!(Boolean)operation.execute()){
//get handle to the last row
Row lastRow = rsi.last();
//obtain the index of the last row
int lastRowIndex = rsi.getRangeIndexOf(lastRow);
//create a new row
Row newRow = rsi.createRow();
newRow.setAttribute("CountryId", newValue);
//initialize the row
newRow.setNewRowState(Row.STATUS_INITIALIZED);
//add row to last index + 1 so it becomes last in the range set
System.err.println("Inserting row at index "+lastRowIndex+1);
rsi.insertRowAtRangeIndex(lastRowIndex +1, newRow);
//make row the current row so it is displayed correctly
rsi.setCurrentRow(newRow);
else{
System.err.println("Data found So not inserting,only setting current Row");
Key key =new Key(new Object[] { newValue});
rsi.setCurrentRow(rsi.getRow(key)); -
Need help with boot up password
Hi I need help with my IBM G41 think pad I when to sleep one night and I put some papers on the keys then close the lid with the papers in between on top of the keys now I get need a password when I started my PC can some some help me with this . Or is there any one whom had this some problem . I see a lock on the screen .
Sorry if this seems like a stupid question, but why don't you have the password already? did the computer just randomly lock you out of it? If that is the case, that would be really strange. If there is no bios password on the computer, you should be able to reset the password in the bios.

Need help with a terminal command
Ever since Lion, or maybe even earlier, I am fighting a losing battle against memory leaks on my MacBook Pro. Safari for example takes over time 2GB+ for just 2 or 3 tabs open with almost no extensions active. Really strange.
Someone told me about the "purge" command in Terminal to free some of the sequestered memory, so I am doing this a few times a day to be able to use Photoshop, Keynote, Premiere and other stuff concurrently without opening and closing apps like I did 10 or 15 years ago, remember those days?
So here are my 2 questions:
Will this frequent "purge" command harm anything in the long run?
If no, is it possible to automate this "purge" Terminal action somehow? Maybe a desktop icon to click, or fully automated? I am a designer, not a coder, so I would need help with that.
Thank you for your input!

It would block usage of all the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option, and Shift, as well as booting from anything but the Hard Drive.
Force Removing Password Protection
1) Add or remove DIMMs to change the total amount of RAM in the computer.
2) Then, the PRAM must be reset 3 times. (Command + Option + P + R).

Need help with BARS 4.0.12 - 4.0.13 upgrade
Hello,
I'm a VoIP noob and need help with a BARS upgrade. To resolve a known problem (Bug #CSCsi32637) we need to upgrade BARS from 4.0.12 to 4.0.13. This is per TAC. However, no one in our company has done this before. I've reviewed the 4.0.12 Admin Guide since I was unable to find any admin docs for 4.0.13. However, I have several questions about this upgrade that hopefully someone here can help with:
1) The install for 4.0.12 requires a reboot of the server. Is this the same for 4.0.13?
2) CCM version is 4.1(3)sr6; any problems known with BARS 4.0.13 and this version of CCM? I didn't see
anything in the Rel Notes or via the Bug Toolkit (figure it never hurts to ask).
3) Will the previously input configuration settings (i.e., Data Source Servers, Storage Location, Schedule) be preserved or will I have to reinput these settings?
4) Any known issues with performing this upgrade while controlling the server via VNC?
5) The 4.0.12 docs state that "To successfully back up the Cisco Unified CallManager database, the backup server and backup targets must exist in the same cluster and have the same version of BARS installed". So BARS must be installed on my publisher (the Backup Server) AND my three subscribers? I'm not finding BARS on these subscribers now.
Many Thanks for any input,
Brian Read1) Yes, any version requires reboot after install
2) not that i'm aware of
4) you'll need to reconfigure it
5) no
6) although it's recommended there is no real need to backup any other server than the PUB which contains the master DB, any SUB only needs to pull the info from PUB in case of crash and reinstall

[SOLVED] Need help with setting up X
Hello guys am new to the forum and this is my first post here. I am in need of a little help.
Need help with X configuration. It starts like this, I installed xorg-server , xorg-utils, xorg-server-utils. When I tried installed xorg-init it says no package, anyway I ignored and moved on.
Now I installed regular mesa stuff and installed xf86-video-ati driver for my HD4250 graphics adapter. with libgl and ati-dri (I have old arch wiki print so it mentioned to install those while newer doesn't list some stuff)
Now the problem is that Xorg -configure doesn't work with newer X and nor the packages has generated /etc/X11/xorg.conf file.
Anyway I created the file manually and added each and every section as mentioned in the "old" guide that I have.
I even added a /etc/X11/xorg.conf.d/20-radeon.conf file for my graphics card with the content as
Section "Device"
Identifire "r"
Driver "radeon"
EndSection
After manually creating all such files I installed x-term, xclock and twm. But when I tried to start X by startx or Xinit it says command not found. Add to that a simple X shows couple of errors.
Please see the errors here Paste #399362 | LodgeIt!
Some more questions : My old guide mentioned to install HAL while newer guide on the net mention DBUS. Though I have added DBUS to be on the safe side but why not HAL ? Is it because of Udev ?
So please help me getting X up and running.
Regards
Last edited by Shashwat (2011-06-04 09:47:47)Ok I sorted out the misprints in the file and installed xinit but still can't get it to work.
1. There are few errors in xorg.conf that I cannot make it out.
2. The X output says no screen found. ?
http://paste.pocoo.org/show/399383/
Now when I add EndSection at the last its says invalid parameter and when I remove it, I get an error "No EndSection, EOF missing"
Kind of bugging
Please do help. -
Need help with iMac intel desktop - Mac mail consistently going OFFLINE
I need help with Mac mail - it is frequently going "offline" and requesting me to "take all accounts online". My internet is working. It's been checked, checked and checked. Sometimes it just takes a reboot of the system and the modem to kick it in and make the little triangle symbol go away, but should I have to reboot daily? I have the Mac OS X Lion 10.7.5 installed. Is there a bug here or am I supposed to upgrade to Mavericks? Any help is most appreciated.
For me this is an issue caused by my email service provider. When they are slow to respond or to accept the password Mail takes that as a password rejection, and prompts me to reenter password, and eventually goes offline.

Need help with trim and null function
Hi all,
I need help with a query. I use the trim function to get the first three characters of a string. How do I write my query so if a null value occurs in combination with my trim to say 'Null' in my results?
ThanksHi,
Thanks for the reply. What am I doing wrong?
SELECT trim(SUBSTR(AL1.user_data_text,1,3)),NVL
(AL1.user_data_text,'XX')
FROM Table
I want the XX to appear in the same column as the
trim.The main thing you're doing wrong is not formatting your code. The solution may become obvious if you do.
What you're saying is:
SELECT trim ( SUBSTR (AL1.user_data_text, 1, 3))
, NVL ( AL1.user_data_text, 'XX' )
FROM Tablewhich makes it clear that you're SELECTing two columns, when you only want to have one.
If you want that column to be exactly like the first column you're currently SELECTing, except that when that column is NULL you want it to be 'XX', then you have to apply NVL to that column, like this:
SELECT NVL ( trim ( SUBSTR (AL1.user_data_text, 1, 3))
, 'XX'
FROM Table
