Okay, here are a few tips.
1) How can we take output returned by Stored Pocedure?No way am I going to take any stinkin' output from some db-jockeys
half-arsed stored procedure. Ask yourself, who's the boss?
2) Diffarence b/w MVC1 and MVC2 ?
1.
3) Why SinglethreadModel is deprecated?
Because the 't' wasn't capitalized.
4) while useing polymorphisam what's wrong with instanceof() method?
Because the compiler keeps having problems with those parens.
5) Servelt chaning follows which designpattern?
The Carol Channing Pattern. See the Hello Dolly anti-pattern.
7) What are genarics in java ?
Classes that are old and in the way,

A ALV with some editable fields which have dictionary search help

Hi all:
There is a requirement to implement an ALV with some editable fields which have dictionary search help, do you have any idea?
thank you very much

Hi - yes it can be done.
1st in your object select the component SALV_WD_TABLE (ALV component) * do all the bindings of your component to your VIEW, Component usage interface, etc.
When you are declaring your context node attributes if you add a TYPE Data element that has a search help bind to the data element it will be accessible in your ALV or in the Attribute there's a INPUT HELP that option that you can add the search help there but you need to have your ALV input enable
for example:
data: lr_input_field Type Ref To cl_salv_wd_uie_input_field,
lt_column Type salv_wd_t_column_ref,
ls_colum Type salv_wd_s_column_ref,
lv_value Type Ref To cl_salv_wd_config_table,
l_col_name type string,
lr_cmp_usage Type Ref To if_wd_component_usage,
lo_interfacecontroller Type Ref To iwci_salv_wd_table.
lr_cmp_usage = wd_this->wd_cpuse_alv( ). *ALV is the name you enter for your component usage when declaring component SALV_WD_TABLE at the beginning.
if lr_cmp_usage->has_active_component( ) IS INITIAL.
lr_cmp_usage->create_component( ).
endif.
lo_interfacecontroller = wd_this->wd_cpifc_alv( ). *once again your ALV name
lv_value = lo_interfacecontroller->get_model( ).
lt_columns = lv_value->if_salv_wd_column_settings~get_columns( ).
Loop at lt_columns into ls_column.
l_col_name = ls_column-r_column->get_id( ).
create object lr_input_field
exporting
value_fieldname = l_col_name.
ls_column-r_column->set_cell_editor( value = lr_input_field ). *this will made all your columns input fields
endloop.
hope this help!

HT1218 My airport utility no longer works, but I have just changed my router. Is there something I need to do ? The orange light shows up on my airport, rather than the green one it should have. Please help !!!

My airport utility no longer works, but I have just changed my router. Is there something I need to do ? The orange light shows up on my airport, rather than the green one it should have. Please help !!!

**** little info about your equipment.
If you just replaced the router with an Airport Extreme or Express:
disconnect the modem from power, disconnect the new router from power, connect the modem to power and wait till it os fully started up, then connect the new router to power. After a while the amber light will turn to flashing, then after a while it will turn to green. Then with AirportUtility (in Aplications/Utilities) it should be configured with the password.

Hi Kellyssi,
Thanks for visiting Apple Support Communities.
If you're being asked repeatedly to check terms and conditions, try restarting and then resetting your iPhone:

Iphone 3Gs updated from 4.1 to IOS 6 but have issue, please help!

I bought this phone from UK and got jailbreak Pakistan.
It was running okay until I decided to upgrade from ios4.1 to ios6 because whenever I was trying to open facebook, safari was crushing.
Now its updated to IOs6 and I was taken to the activation screens, and begun with the welcome one, choose language, choose location services (later on it also disappears) and selecting Wi-Fi and/or iTunes for activation.
I chose a Wi-Fi network the process started, and gave me a message that it will take about few minutes to activate iPhone, few minutes later a screen with this message appears: "Your iPhone could not be activated because the activation server is temporarily unavailable."
Then, I decided to try the activation using iTunes. But alas no luck using iTunes, after few minutes, it shows the following message:
We're sorry, we are unable to continue with your activation at this time.
Please try again later, or contact customer care.
I tried several times in both ways so I started to find out some info about this trouble over the Internet but I did not find any answer or solution either!
Now I dont know what is wrong and what to do, please help. Thanks

That's your problem, iTunes has detected a jailbroken device & errored out. Apple does not support jailbreaking & when detected, by iTunes, you get the result you're experiencing.
We can't help you here, you'll have to use Google & search for a site that can help you.
Good luck.

Image capture deleted all my photos from iPhone without transferring them to the harddisk. So now I've lost 427 photos due to some data error it says. Please help me get my pictures back!?!

I just wanted to back up my photos since I haven't done so since October 5th. I plugged in my iPhone and let Image Capture transfer the selected photos to the designated folder. Accidently I hit 'Import All but that's not the biggest problem. Apparently I had "Delete all after transfer" on AND 427 photos apparently "failed to transfer" as it said. I didn't think it was such a big problem, but then I noticed : what the ****.The delete all option was ON and now ALL my photos are gone, from the iPhone and NOT on the computer. Except a list of some old pictures I already have three backups and from the new ones between Oct 5 and this day I have a random selection >><!!!
So please help me! How do I get my pictures back? iPhone Data recovery? Please please help. There are so many nice memories of this month and I'm so ****** that this just happened!

If you have iCloud backup turned on or if you have recently backed up via iTunes you could restore the phone from either of those sources. Camera Roll photos are included in those backups. Be aware that doing a restore will replace the contents of the phone with the contents of the backup so you would lose anything new on the phone since the last backup. Back up and restore your iPhone, iPad, or iPod touch using iCloud or iTunes - Apple Support

. I am new to IPods. I have a Classic 160GB and I can't figure out how to load my music videos to it. I have had no problem loading my music CD's but no go with the music videos I have. Please HELP. Thanks maxsdad

Hello:
I am new to IPods. I have a Classic 160GB and I can't figure out how to load Music Videos to iTunes or the IPod. I have had no problem loading my CD's to iTunes and to the IPod, but no go on the Music Videos.
Please Help
maxsdad

B-Rock:
Ok. Here's the results. I tried all the music videos I wanted to put onto the IPod and the results were:
I was able to get good results with 2 full length music videos and 2 video singles(only 2 videos on each disk). For a total of 4 videos.
I was able to encode 5 full length music videos, but the results were distorted (video and audio).
I was unable to copy 2 full length videos due to error failures. 1 was a "No Title Found" error, the other was a "NAVDAT" error.
I guess my next question is: Do you know of any other program(s) that I might try, to see if I can get good results with the videos that didn't work with Handbrake?
Thanks again for all your help.

SOME ONE VERY GOOD WITH ITUNES PLEASE HELP!!!!

wen i go to add file and select the file itunes opens but nothing happens i have so much space on my ipod i dont understand it PLEASE HELP ME!!!!

Alexl08
I suspect these are files downloaded from Napster, Rhapsody, Sony, Walmart, or some other online store that has WMA copy protection.
Those files will not work in iTunes.
That's why Dave was asking WHERE you got them.
To get them into iTunes, you need to burn an audio CD using Windows Media Player (or some other program that can play the files) and then, import them into iTunes.
The DRM copy protection between Apple & Windows is incompatible. That's why iTunes won't let you drag them in - it can't play them. And Windows Media Player can't play sonfs from the iTunes store.
Ah, the joys of DRM: digital rights mismanagement.
edit: if you hover your mouse over one of those files in windows explorer, the little baloon info will pop up and say
Protected:Yes
You can only drag Protected:No songs into iTunes.

ALL SHAPES LAYERS SUDDENLY CHANGED COLOR WITH SOME ACCIDENTALLY USED KEYBOARD SHORT CUT PLEASE HELP

I was working away in photoshop on an INCREDIBLY important file and suddenly all of my shape layers inverted... there is NOTHING in the history and I have literally tried everything I can think of. this is seriously a crucial issue and i really need this to be fixed. if ANYONE knows anything please help. I'm posting a screenshot of what it looked like and what it looks like now. naturally adobe wont let me call them or do ANYTHING to get immediate help with this absolutely infuriating problem so if someone out there could help that would be great. SERIOUSLY regretting using photoshop, it is so infuriating even after 7 years of using it.
^^ this is what the colors looked like
and VV this is what they look like now. as far as i can tell, its only the shape layers that have changed color. I have tried everything and nothing works.
roughly, all the yellow turned green and all the red and white turned black? I have no idea. please PLEASE someone help me.

The colors are present even when I exported Jpegs from the photoshop file. Gamut warning is off. the difficult thing with screenshots is that the image appears in different colors at different sizes... which is bizzare.. at the full shape, some of the shape layers appear fine as pictured below
and then when i zoom in this happens

I recently reinstalled Snow leapod on my mac because I was having problems. I backed up everything onto disks, but after formatting, i quickly realized that some files did not transfer. I am missing some very important video footage. Please help me!

I recently re-installed Snow leapod onto my macbook. Previously the system was running snow, I believe I may have visited a corrupt website or something. Anyhow, I backed up all of my information onto disks before reformatting, and the format went well. However, I realized after the fact that some important video footage did not transfer to my DVD-R's that I saved my data too. Is there any possible way I could recover this information? I'm trying to recovery software I found recomended online, but im not sure what the outcome of it will be. I know things are not looking good, but was hoping someone could please help me.

Also, as for what I did. I put the OS disk into my computer, restarted it and ran through the screens to completely reinstall the OS. Then, I had to install my Snow Leapord CD because my origional OS was not the newer SL. Its my own fault, I just didnt think of every file off the top of my head before startign the process. I assumed everything was on the backup disks I had just burned.

I have just updated the i06 software for my ipad and it will not connect to my home wifi network - all my other devices are able to connect - i have tried all troubleshooting options and none have worked - please help

I have just updated the i06 software for my iPad and it will not connect to my home wifi network - all my other devices are able to connect to my wifi network.
I have attempted all troubleshooting actions suggested and nothing has worked. I have restored my iPad network and factory settings - Please help - this is frustrating me

you have to set up your router to solve th problem. first find and write down the ipad mac address.
then log on to your router using your laptop or any device that can connect to router at 192.168.0.1 in your web browser. please check out my posting about how to resolve the wifi connection problem.
i think the ios6 update has reset the networking but if you set up the router then you should not have the same problem any more.
