Any tricks to regain signal after a loss?

Greetings! All is well with my 3G. Really impressed. Just one question for you experts. I was wondering if there was any clever way to make the phone look for a signal rather than just waiting for it to do so. For example, my office is too far into the building to get a signal, but if I walk to the atrium I can get a signal.
Thanks

The iPhone along with all GSM and CDMA phones are always searching for a signal so the iPhone isn't waiting to do anything in this regard. If there is no signal, it is only waiting for an available signal to connect with but is always actively searching for an available signal.
If there is no signal and you know there is no signal in a location where you will be for a while, there isn't anything you can do but turn on Airplane mode to increase battery life. The lower the signal and when there is no signal, the iPhone will use more battery trying to maintain a low signal or acquire a signal if there isn't one available.

My computer cant pickup any LAN or wireless signal after being infected by a virus?

I posted this yesterday and tried almost every anti virus program that I could download off the internet. I'm in Afghanistan, hence no help over here.
My wireless cant pick up the Router nor can it pick up the LAN when I put a cable in. The two computer icons don't even turn bleu, it's just got a red cross throe them.
This happened a few munites after I opened an email, the hole connection just went dead and I can't find any anti virus that'll detect any fault. Can this be a virus? What kind of virus? What can I use to get rid of the virus? If not a virus where and how can I do fault finding. I have VISTA 64-bit, HP Pavilion dv9000 laptop. Thanx

Once the Device is in Recovery Mode... it is too late to save anything...
To minimise loss... after the successful Recovery... Restore from the most recent Backup...

TS4429 NO SIGNAL AFTER UPDATING LATEST SOFTWARE ANY HELP PLZ

got no signal after downloading latest software anyone help please

Hi norrod
If you hadn't already been to the phone shop I would have said it is most probably a hardware fault in the antenna circuitry of the phone.
Can you remember the phone being dropped at any time?

Any tricks to use PL/SQL types in object attributes?

I guess this is a bit of a newbie-question, but I haven't been able to find any workarounds elsewhere, so please bear with me... I'm far from new to object orientation, but I'm rather new to Oracle's object features.
I was wondering if there's some trick you can use to keep references to attributes of PL/SQL types even though they are not allowed in object types (as these are "SQL", yes I do think I understand). I was thinking there might be some way you could cast them to some data type that is supported in SQL and then get them back by the reverse process when you need them in the PL/SQL inside the methods?
In the concrete case, I would like to keep a reference to a utl_smtp connection in my object. It doesn't matter that the reference would be meaningless in other sessions etc. (actually I may not even want to store the objects in any persistent table - it's the polymorphism I'm after):
CREATE OR REPLACE TYPE o_test AS OBJECT (
att1 NUMBER,
att2 sys.utl_smtp.connection
- which of course give me:
LINE/COL ERROR
0/0     PL/SQL: Compilation unit analysis terminated
3/12     PLS-00329: schema-level type has illegal reference to
     SYS.UTL_SMTP
The problem becomes rather dull since I can't pass the connection record as a parameter to methods either.
The only workaround I could think of was to keep the connection as a global variable in a PL/SQL package and then get it from there inside the methods. Of course this can be refined using an index by table and some object unique id to support multiple objects with their separate connections. But it still seems rather clumbsy - especially given that what I was looking for was the elegance of polymorphism.
Any tricks I don't know of?
I'm working in Oracle 10gR2.
best regards,
Jakob

The UTL_SMTP Connection record is not too complicated, and can be easily translated into SQL object types. Add a package to aid in conversion between SQL and PLSQL, and voila!

8.02 POA crashes w/ntdll.dll fault after power loss

Hi,
Running GW 8.0.2 on Windows 2003 server (POA, MTA and GWIA). After power loss on Friday, POA will not stay up for long - crashes with:
"Faulting application gwpoa.exe, version 8.0.2.10840, faulting module ntdll.dll version 5.2.3790.4455" error.
MTA and GWIA are not crashing.
I thought maybe it could be a corrupt message but the only messages in the queues are dated today and not Friday (\PO\wpcsout\ofs\4 - wpcsin queues are empty). I am currently running gwcheck.exe against the message databases but that is going to take a couple hours. Any thoughts? Thanks.

I am having the exact same problem. Below are the specs of my GroupWise servers:

The POA will randomly shut down with an ntdll.dll error fault. I have migrated this server to new hardware and a new OS (user to be on a 2003 R2 SP2 server and half the RAM). Same issue. Anyone have a fix for this?

WRT610N v2 - Dropped signal after macbook goes to sleep

Hi there,
My wireless G macbook drops the signal after it wakes from sleep mode. I also have a similar issue with my PC and the WUSB600N but I believe that one is the adapter issue. Can you think of any reasons why this would occur? Troubleshooting?

Is your Mac computer is wired or wireless...?
open the router setup page and Under the Wireless tab,Click on Advanced Wireless Settings..Change the Beacon Interval to 75,Change the Fragmentation Threshold to 2304,Change the RTS Threshold to 2304 and Click on Save Settings... Now,check.
As far as the WUSB600N is concerned,try updating the driver for that.

Any tricks for shooting green screen with C300?

Any tricks to shooting green screen with C300?

Sounds like the color space conversion is simply intensifying compression artifacts that are there in any case. It's a compressed format, after all. You might need to check some specific CoDec options to get a better conversion. Short of that I have no idea, since I don't have access to such files ATM, but if you can provide a short clip somewhere (rapidshare, yousendit etc., ca. 30-100 MB), I might have a look and be able to offer more specific guidance how to work around the issue.

Hello, I have updated to the newest Pages and yet when I open a document to use it says, "You need a newer version of Pages to open this document." When I got to install it again it says I have already done that. Anybody have any tricks? Thanks!

You have 2 versions of Pages on your Mac.
Pages 5 is in your Applications folder.
Pages '09/'08 is in your Applications/iWork folder.
You are alternately opening the wrong versions.
Pages '09/'08 can not open Pages 5 files and you will get the warning that you need a newer version.
Pages 5/5.01 can not open Pages 5.1 files and you will get the warning that you need a newer version.
Pages 5.1 sometimes can not open its own files and you will get the warning that you need a newer version.
Pages 5 can open Pages '09 files but may damage/alter them. It can not open Pages '08 files at all.
Once opened and saved in Pages 5 the Pages '09 files can not be opened in Pages '09.
Anything that is saved to iCloud is also converted to Pages 5 files.
All Pages files no matter what version and incompatibility have the same extension .pages.
Pages 5 files are now only compatible with themselves on a very restricted set of hardware, software and Operating Systems and will not transfer correctly on any other server software than iCloud.
Apple has not only managed to confuse all its users, but also itself.
Note: Apple has removed over 95 features from Pages 5 and added many bugs:

Archive/trash Pages 5, after exporting all Pages 5 files to Pages '09 or Word .docx, and rate/review it in the App Store, then get back to work.

Can't open any windows in Safari even after re-install

I can't open any windows in Safari, even after installing Snow Leopard, not even the "About Safari" info window. I'm using Firefox to get online. I can open the program itself, but can't do anything else. I'm suspicious that it may be a virus, because I'm getting some weird messages on restart, such as asking me if I want to use some wireless network I never heard of, and if I want to give somebody access to my Twitter account - very strange. My son was using a website when this happened.

Greetings,
I'm suspicious that it may be a virus
Not possible, since there are no viruses for Mac OS X. You should ask your son what site he was one and whether or not he downloaded and installed anything. And you should turn off wireless networking and delete any networks that you didn't specifically setup. Use Ethernet to connect to your modem/router for Internet access.
Are you sure that Twitter is asking to give somebody access to your account, or just authorize them to follow your tweets? I've never seen Twitter do the former for anyone, ever.
