GrabPixel() not working - ImageObserver.ALLBITS- HELZ PLZ

I capturing an image form a camera (that works). Now I want to process the image so I call grabPixels but i get a problem. The bug occurs in the following piece of code.
PixelGrabber pgObj = new PixelGrabber(
          rawImg,0,0,imgCols,imgRows,
          oneDPix,0,imgCols);
try{
if(pgObj.grabPixels() && ((pgObj.getStatus() & ImageObserver.ALLBITS != 0)) {   .. .etc etc
So the problem is that ((pgObj.getStatus() & ImageObserver.ALLBITS != 0)) returns false. Same happens when I use ImageObserver.ERROR, ABORT and PROPERTIES.
However it returns true when i use ImageObserver.FRAMEBITS, HEIGHT, SOMEBITS and WIDTH but the image i get is extremelly messed up (like disturbed by vertical black lines and u can hardly recognize a thing).
Does anyone have an idea about what the cause might be?
I would really appreciate some help!

um..pretty simple solution. when you bought this iphone its obviously still linked to the old sim which is probably a UK carrier. you need to contact whoever you bought it from and get them to pay the fee to use this phone on a saudi arabian sim.

Hey miah-hamid,
Welcome to the BlackBerry Support Community Forums.
Thanks for the question.
Do you have a BlackBerry data plan with your network service provider? I would suggest connecting to a Wi-Fi network and then wait for the BBM Setup screen to finish.
Let me know if the issue still persists after 15 minutes.
Cheers.

App Store Is Not Working ??? plz help

Hey guys I updated my iPod (4th generation) to iOS6.1.2 about 2 weeks ago but suddenly yesterday my App Store stopped working. When I open it it's all blank in features,search,etc?? Plz help how can I make my App Store work ??

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Go to Settings>iTunes and App Stores and sign out and sign back in
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

hewlet packard Windows XP

hi April!
just doublechecking something. is the download hanging at the initial phase of proceedings? or is this happening after the installation has actually pretty much completed?
if it's at the later stage of proceedings, are you getting a sort of "brief flash of a license screen? or is something else a little different happening?

Reverse SSH not working for Cisco 3750.Plz help.

Hi,
I have configured the reverse ssh mentioned on the cisco document:http://www.cisco.com/en/US/docs/ios/12_3t/12_3t11/feature/guide/gt_rssh.html#wp1051457.
But now I am running into the issue that When I issue command ssh -l alex:rotary1 192.38.6.8 from the cli of the router I’m presented with a password prompt.
I enter my password and get connected. However at this point when I type, for example, the atdt command I don’t see any output displayed.
So I tried typing command atdt <tel no.> and at the same time ran a debug modem on a separate session. It was from the separate session I could see the call been made to the remote device and connected successfully. However almost immediately the modem debug displays message 0236596: Dec 7 2010 12:18:18.236 GMT: TTY69: cleanup pending. Delaying DTR. At no point do I see output displayed on the session where I connected to the modem.
When using telnet to connect, i.e using the same modem and the same remote device, we have had no problems it is just with SSH.
Any suggestion on this will be highly appriciated.
Thanks
Alex.

Philip,
I first thank you for coming forward to help me on this.
I use the 30DM(Digital Modem) Card on the router. I have configured on of this modem on the PRI card(1/18) to make outbound calls. We use this dailup to cyclades the devices located on our remote office. Hence we loose the main internet connectivity we use this option as a backup.

Please let me know is this a bug or anything else. AS the same setup works fine when I use TElnet rather than ssh.
Thanks in advance.

Increment of + 1 not working properly for KUNNR

Hi Guys,
I might be asking a very basic question,but tried several ways not found a solution.
Lets say I have a Customer No KUNNR with value '0000000111'.
I am doing a increment for this KUNNR like + 1.
When I am adding +1 to KUNNR with value '0000000111' , the result is becoming '112'.
But I want the result as '0000000112'.
How to achieve this.
I used counter type as kunnr.
Assigned this Counter to '0000000001'.
But still not working.Could any one plz suggest.
Waiting for your reply.

Haven't heard or came across any requirement where you add something to KUNNR.
If you are populating a new KUNNR, use number ranges.
But just for your info, if you want to increment, you need to apply conversion exit 'CONVEXITALPHAINPUT/OUTPUT routines and store in KUNNR variable.
BTW appreciate if you can highlight your requirement of adding 1 to KUNNR.
Regards,
Santosh

Try hard resetting the phone.
Hold down the sleep/wake button and the home button at the same time until the apple appears and let the phone reset itself.
Let me know if you've already tried this or if it works.

My macbook cam is not working after i reinstalled it plz help?

i just reinstalled my macbook os x 10.8.2 but i found out that my camera is disable not working with FaceTime and messenger plz kindly assist me on how to make my cam start working again please someone should help me ...........

Are you sure you are running 10.8.2 or is it 10.8.5. There was an issue with 10.8.5 and the recent supplemental update should fix that camera problem.
If it is 10.8.2, I'm not sure what is wrong. Might try an SMC or NVRAM reset.
