A UNIQUE question...:o)

pardon the pun,
I have a select statement:
SELECT UNIQUE A, B, C FROM TABLE_A, TABLE_B
WHERE TABLE_A.A = TABLE_B.B AND etc...
The problem is that I need a distict row (ie 1) on A and because C varies the query returns multiple rows.
Any suggestions would be appreciated. I thought of using LIMIT but again this only applies when there are duplicate rows on all result rows.
regards
James

hmmm..sorry I should have expanded.
the query returns a result for C like:
1
1
1
34
34
34
34
65
65
65
65
65
and I only want the one occurance of C ie 1, 34, 65.
regards

Skier unique question regarding password for Flash Player

I keep getting told to update Flash Player but my password for Adobe is not accepted for the Flash Player sign in. How do I get a password for Flash Player?

This password prompt is presented by your operating system, and is intended to keep you from accidentally installing software.
If this is your personal machine and you don't need a password to log into the computer when it first starts up, you can probably leave the password blank and click OK to get past this prompt. If this is your personal machine and your normal password isn't working, check to make sure that CAPS LOCK is off, and type the password carefully.
If this is your work machine and it's asking for an Administrator password, well, you'll need to have a conversation with your friendly IT person.
If you're still stumped, you may need to reset the password on your Mac:

Transformation Question

Hi,
I have a unique question for everyone.
In one of my data load into a DSO, i need to update a target field either as override or Summation based on a input flag field.
Is this possible. I am open to writing code in any of the transformation routines.
Thanks
Niveda Sharma

Yes, you may have to write an End Routine & also read the same DSO which could cause long load times. Just evaluate and see if its worth it.
The logic would be in END Routine:
For the keys of the DSO (Result_Package) read the DSO with the same keys.
Based on the input_flag, add result_package-kf to DSO-kf, if you have to sum
else overwrite result_package-kf, if you have to overwrite.
Hope this helps

Allow users to create Challenge Questions in OAAM

Hi,
I have OAAM 11.1.1.5 BP01 implemented and integrated with OIM and OAM 11.1.1.5.2.
I want to know if a user can be provided with the functionality to create his own challenge questions instead of selecting the OOTB ones.
If yes, what would be the implementation steps to achieve this?
Please respond.
Thanks,
-Kulesh...

AFAIK, no. You can definitely customize the existing challenge question set to add/edit/remove any number of questions from the OOTB defaults per your client/organization's requirements... but on an individual user level, there is no functionality to custom define their own unique question/answer set.

LCD Touchscreen Question

Hello,
I have a 42" LCD Touchscreen (from Panelworx) with a integrated CPU that connects to the screen via HDMI. I am running a Flash Projector file in 100%, Fullscreen mode, developed using AS2, CS3. The problem/question is when we shut the monitor off and turn it back on the Flash Projector file is completely white, but if we dont have it in fullscreen and turn the monitor on/off everything comes back just fine. Turning the monitor on/off is necessary for the customer so I have to figure something out. I know it is a unique question//problem but I was hoping someone would have some insight, suggestions, similar story...
Thanks in advance for any advice!

SD feeds into an HDTV will look like SD.
Not necessarily. There are a number of LCD HDTV's that sport features intended to "pull" the primary objects in a picture "towards the audience," which can add a great deal of depth to even SD programming. Although such options don’t result in a higher resolution being displayed, they do typically mean that you might have an easier time distinguishing people and moving objects from static backgrounds when compared to watching the same image on an old CRT model. I believe that Philips calls this function Pixel Plus 3 HD on their TVs, but different manufacturers will obviously call it by different names.

Unique random alpha num string

Hi Guys,
I have a unique question.
I need to generate a unique random Alpha Num string.
I cannot use 0,5,8 and 0,S,B in the generated output string.
The string generated should be no more than length 7 max
Pls help.

Following solution generates random unique strings combinations
from any given base set. Here is a sample output.
$ java UniqueStringGenerator 7 100 10
FCT2RYT
2M31BU8
VV8FU4Z
BON2MKE
OKUJZT0
68E8X8S
YTNLZAY
CPEKPFP
C176M24
GQB9QE9The idea is quite simple.
Pre-work:
1. The base set is first mixed to increase entropy.
2. All possible combinations are divide up into random buckets.
Work for every unique string:
1. Pick a bucket at random.
2. Get next number in bucket.
3. Convert the number to a unique string token.
It is possible to adjust how much entropy you want in your
sequence of generated combinations by choosing how many buckets
the generator contains. However, every bucket will take up some
memory.

Get dynamic values in Jsp fom Applet

Hi,
Mine is not a unique question, its been asked many times on the same forum but still I havent got any satisfactory answer so I am putting this again.
I have one applet, it is been loaded from jsp. Applet uses double buffering and its values are changing constantly.
Now my question arises here, In my jsp i have one button on the click of that button I am calling some other jsp passing some of jsp values in URL. I also want to pass one of the value of applet to jsp so it can pass to next jsp or to do something that next jsp automatically gets the new value.
I thought for Applet-servlet communication but my concerns are,as my applet is being refreshed continuously(around every 1 sec) and the value which i have to pass is changing every second and I dont know when user will click on the button of jsp so to pass that value of applet i have to do applet-servlet communication every second and that does not suit me as it consumes lot of time.
Can you suggest me any other solution so I can send value through jsp whenever button is clicked.
Thanks
Taral Shah

HI Senthil Babu
Thanks for your reply.
But applet is very important for my application as i am showing some graphical representation on it. So I have to use applet. Now you told that i have to make temporary files on client's macvhine. You mean to say each time I have to store that value on client's pc through File I/O.
Is that? but that is also problematic 'cause it consimes much time and my application deals in milli seconds.
Pl. guide me considering that time is much important for my application so solution should not consume much time.
Thanks again,
Taral Shah

IPad 1 - VGA cable not outputting to projector, monitor or TV?

I recently purchased the apple VGA cable so that i could project powerpoint presentations using my iPad 1. I have no success at all using any applications to make this work. Slideshark, Keynote etc.
I had read that only video streaming is supported, however, i cannot get Youtube or any other content to show up. The cable works fine with my iPhone 4S.
Is there a setting I need to adjust on my iPad? When I plug it into a computer monitor, projector, or TV it seems to detect a signal but the screen stays black.
Any help would be very much appreciated.
Aleks

Thanks all... of course after I posted the query, I decided to do a forum search and found that this was not a unique question...in fact the VGA connector for the iPad1 is about useless. I did do a Slideshow and the images DID display on the external monitor. So the system does work, albeit with some decided limitations.
Well, not a reason to get an iPad2 yet, this was an experiment and not a regular requirement for me.
Still.... an odd decision by Apple to be so selective about what it allows to clone. And while they are at it, next time around, an extended desktop option would be really, really neat.

Using Spry in Sharepoint

I'm currently setting up a Sharepoint site for our
organization. We are currently replacing our old Intranet with this
new Sharepoint site. On our old Intranet, I used some Spry for a
couple of things. I'm looking to bring the Spry over into
Sharepoint. I was wondering if it can be done and how I would go
about doing that.

Thats a very unique question. I am sure it can be done
however, its just a mater of how you develop or build out the
webpart you wish to have drive this. I think you might have to
build a HTML based webpart to perform the work, and then figure out
how you may want to use the content pages to feed the spry/HTML
based webpart the data.
What specifically are you looking at doing? Also is there a
webpart to do it already. WSS 3.0 has some great gains over the
past but I like the way you looking to customize it. I might just
have to try that myself later today.

Automate oracle password reset via procedure

I want to create a web application that I can call a stored procedure, pass in the username, and application that the user is trying to have their password reset on. Reset their password to a temporary password, and email the temp password to their email account. Once they get the temp password, they can login into the system, and change their password.
The java part probably not a problem. Does anyone know how to create a procedure to act as sysadmin, and reset passwords temporarily?
I know it can be done. The only problem is that I am on 8i, and 9 for the databases. I have about 5 - 6 different applications that they can change their password on.
thanks ahead of time.
orozcom

What do you mean by "application"?We do have a number of home grown applications that require username, and password.
Some of these application use the standard ldap username/password. So resetting the password here may also reset other application passwords as well. Yet some of our application have their own unique way of resetting the password for the application. I am hoping to copy the way that a sys admin usually does this and replicate it using java. Some are command line, other are through the use of a tool used by the application. So far I have been able to replicate most of them using java. I am still working on 1 other. 5 out of 6 not bad. Anyway, we would like to go to one place to reset the password for a user, and then email that temp password to them. Of course we will have some sort of authentication to change the password, such as unique questions they must answer, etc...

Can't find iweb

I am looking for iWeb on my MacBook. Is it currently available? Please advise.

Your unique question is asked on a daily basis on this forum. Suggest that next time, you do a forum search before posting.
Otherwise the answer is the same as Roddy's - go to the Apple store online and purchase the iLife 11 boxed set that contains both iWeb 09 and iDVD or go and look on Amazon and you might get a copy more cheaply and then just install both iWeb and iDVD onto your machine in the normal way.

IWeb won't display different Domains after upgrading to Lion?

After upgrading my MacBook Pro to Lion 10.7.2 my iWeb 3.0.4 program won't open different Domain files. Even though I have several different Domain files on the hard drive, no matter which one I try to open it always shows up as the last Domain opened by iWeb. If I remove the last opened Domain file from the hard drive and try to open one of the remaining files everything is OK, except if I again try to open a different Domain it also shows up as the last opened file.

Your unique question is often discussed.
Search this forum for Lion. You'll find this answer :
where do I find "domain" in Lion?
Or look to the right where it says : More Like This.
Or have a look at this movie :
http://www.wyodor.net/_Demo/Aptana/iWebSites.html
Or wait for our resident technology experts to provide the answers from the search.
