How to concatenate two colums into one single column

I need some ideas to concatenate two different columns into one single column using a set of distinct values.
For Example,
Customer Product Number
xyz A 1
xyz B 2
xyz B 1
AAA C 7
AAA A 1
The result should look like this,
Customer Value
xyz A1 B2 B1
AAA C7 A1
How would I group this into once value ?
Thanks in advance ...

Problems with Syncing two different libraries on one mac

Ever since I downloaded itunes 11 onto my mac I am having problems with syncing. We have two libaries on our mac and can still easily move between the two, each keeping our own playlists, and music/podcast libaries. The problem is with the syncing to our ipods. The playlists stay separated, but unfortunately the sync update pulls both music libraries and puts it on each of our ipods. Having very different music tastes, this is a drag.
A second issue - there is still that problem of having issues with purchased music not staying in playlists (on ipod) after syncing.
I've tried looking around the itunes tutorials and articles but wasn't having luck. any feedback would be greatly appreciated.
Oh, in case it matters, one of us is using an Iphone and the other an ipod touch.

you might have to find a third party program to get those songs off her ipad onto the computer, apple doesnt support that unless they are purcahsed from itunes store because of DRM (Digital Rights Media) another word for copy write. so theres not a whole lot of hope for that, but you can always create a new user on your computer
>user>+ icon>Create new user make it admin
-if they are how ever purchased from itunes you would still make that new user, plug the device into itunes and authorize the computer by clicking store on the top of your screen where file edit and view are, Store>authorize this computer
once thats done you'll then plug that device in to the computer and on the left side of itunes you'll see devices and "Device name" the device its self, right click or control click the name and choose transfer purchases, anything that has ever been purchased of gotten for free will sync onto the computer,
you cant just simplay pull the songs off the device to the computer, doesnt work like that

Problems With Printing Two Up

Hi-
I have a document that consists of pages that are 5.5x8.5, in other words half of a standard 8.5x11 sheet of paper. I want to be able to print these two up on 8.5x11 sheet of paper. So in the layout section of the print dialog I set pages per sheet to two. The problem is that when it prints each page is smaller than it should be, it seems like it's padding the pages with white space and making them smaller. Is there a way to get around this?
Any help would be appreciated!
Thanks,
Jonathan

You are not the only one with this problem. I have been fighting this issue all day.
I have read the User Manual up and down, I have scoured the support pages, and I have spent untold fruitless hours with technical support... am currently still unable to solve this problem.
When using a Pages template, I am unable to change page size while holding the formatting together. No way to select all and group it - no way to start a blank document with the proper page size and then insert a (template) page, no way to change paper once the template is open....
I have a template from Pages (doesn't matter... pick any one at all that has formatting and objects, not straight text) which opens with a default page setup of paper size A4. Fine. In printer settings, "Choose Layout from the pop-up menu and choose the number of pages you want to appear on each sheet" (page 173, Chapter 10) which makes perfect sense to me.
I am trying to achieve two pages per sheet for a "tabloid" type publication. I wish to print on A3 - which should work perfectly - the page size in the end result (2 per sheet) is in fact A4, because A3 is two A4s laid side by side. So, this is as the formatting intended it should be, because smaller is too small and larger wouldn't work.
When I print I get:
a) the proper layout, but with the size being HALF an A4 instead of a full A4 (half an A3)
b) the right size (when changed in page setup) with formatting all over the map and all the work destroyed.
It is easy enough to say "Before you print, you should make sure the paper size and orientation are set the way you want by opening the Page Setup dialog" (page 169 Chapter 10) but these Pages templates are not able to be printed on ANY size of paper except A4 - the way they have been laid out originally. It doesn't matter which size you're trying to print - an invitation on smaller paper perhaps, a tabloid type newsletter on larger, anything at all on banner paper...
There has to be a fix for this somewhere.
Can anybody help?

Problem with opening two frame by single hyperlink

HI to everyone,
I making a project , in that i want if i click on a
particular hyperlink. then it open two Different frame which is
showing different content . one is in the same page in which is h
yperlink is appearing pelink (means in the same frame ) and the
other frame showing some other content , Robohelp allowing to do
this event seprately but not simultanously............i want to
perform this both frame should be open at same time by single
click...........
plz if any one know solution of this problem plz let me
know.....................
Thank's
Roziao

Hi RoboWizard,
I understand (I think!!!) about how to create a frameset
using the method you detailed. Say I create a frameset with 2
frames: 'TOC' frame on the left and 'Details' frame on the right.
When I create the frameset I specify the default 'TOC' topic as
tralala.htm, which is a basic list of contents. I don't know the
full list of contents to display until the user clicks on a link to
display a topic in the 'Details' frame. I specify the default
'Details' topic as Welcome.htm, which is an introductory topic.
Say my initial Blurb.htm topic (as described in my previous
post) contains two links:
How to make a cup of tea
How to perform a headstand
If I click on 'How to make a cup of tea' I would like to
display my Outline.htm topic in the 'Details' frame giving an intro
about tea and the art or making it, and a task list Contents.htm in
the 'TOC' frame detailing each step in making a cup of tea. When I
click on a link in Contents.htm, it updates to the relevant topic
in the 'Details' frame.
If I click on 'How to perform a headstand' I would like to
display Outline2,htm topic in the 'Details' frame giving an intro
about balancing and seeing life upside down, and a task list
Contents2.htm in the 'TOC' frame detailing each step in performing
a headstand. When I click on a link in Contents2.htm, it updates to
the relevant topic in the 'Details' frame.
However, what actually happens is:
I click on 'How to make a cup of tea'. Outline.htm topic
displays in the 'Details' frame, and the tralala.htm is still
displayed in the 'TOC' frame. To display Contents.htm in the 'TOC'
frame, I would have click on a separate link.
Same problem when I click on 'How to perform a headstand'.
I hope this example explains my problem a little better. Do
you understand?
I'm sure there is something blatently obvious that will
overcome the problem. I've only recently discovered frames, so my
knowledge is not the greatest on this subject and hope there is an
easy answer to solve my issue. I'm hoping for a 'Doh!' moment!
Many thanks for your help.

Problem with using two Nanos with one XP computer

I've got two profiles set up on an XP Home Edition OS. I have iTunes loaded within each profile. When I move from one profile to the other and I exit the iTunes on the first profile and enter the second profile...when I try to launch iTunes on second profile it tells me someone is using iTunes and to continue it must be shut down. I already shut it down...but the first profile is still running. Only when I log off of the first profile will I be able to use iTunes on the second profile. Please don't tell me I have to live with this...thank for any help that you can provide.

Firstly my experience of MS Windows would suggest that although you've shut the application down there's still a whole lot going on in the background tying up the loose ends. If you swap users before this completes then it may be put on hold, hanging onto the program or its config files. This may be completed by logging the profiles off fully.
As previously mentioned you'll have to live with it.

Problem with editing two forms

Hello!
I have two reports and two forms on these reports. The reports actually contain the columns of one table separated in two groups(Report1=group1(column 1-5 for example) and Report2=group2(column 6-10 for example)). So when i select Edit on a row of Report1 i go to Form1 and see the data to be edited of Form1 of row1 for example. I would like to go to Form2(i have a tab for this) and see the same row(row1) to be edited with the columns of Report2.I hope that i am clear enough.
Thanx in advance for any answers.

If you're using the Automatic Row Processing (DML) process, there is a box named "Return Key Into Item" which can return the current key (ID) to a designated (hidden) item. You can then this item's value passing to the next page.

Problems with Disk Two Of Installation

Hi,
I've managed to install disk one of the installation cds and now i'm on my 6/7 time of trying to instal disk two. Everytime I do, it works for a while and then a sign comes up saying 'An error occured while installing Mac OX, then once I click continue it comes up with a box saying 'The installer could not install some files in "/" (or another area) it stops at different places each time and each time I clean the disk and it stops at a different spot. The disk to me looks very clean and has no marks at all.
This mac is second hand. I bought it off ebay with installation disks for leopard however the seller had put on snow leopard. I wanted to downgrade for a few reasons mainly ease of use and compatablity reasons. Neadless to say, now I have installed disk one, there is no way of going back to SL, so if anyone can help I will be very thankful!
Thanks,
Thom

you can call applecare.
(800) APL-CARE (800-275-2273)
give them the serial number of your mac and if it's not two old they'll send you replacement disks. snow leopard can be bought at any computer store for $30.

Problems with syncing two iPhones

My girlfriend and I both bought iPhones the other day and we have an iMac at home (Intel iMac). Both iPhones have been connected to iTunes and, when both phones were connected to iTunes, I don't think we changed users on iTunes (I have an Apple account and she has and Apple account as well).
At some point, I tried to import my contacts from Yahoo and, at some point, she plugged her iPhone into the computer as well. We both ended up getting all of my contacts and all of her contacts (she tried to sync as well) on both phones. In addition, any time I try to download an application, it asks me for her password. Also, when I connected my iPhone to the iMac last night, it automatically synced and provided me with all of her applications.
Is there any way to solve this problem apart from "restoring" both of the phones?
Thanks for any help that you might be able to provide.

Set up a second user account. From that point on everybody can have his/her own music, calender etc.

Problem with layering two still images

Hi,
I am trying to create a simple transition between two still images (the first one is in V2 and the second is in V1, with overlapping). I noticed that when I add a video transition (like cross dissolve) the second image becomes blurred and out of focus. This creates a noticeable jump: the emerging second image is first seen blurred and then suddenly becomes focused again. When I took out the transition, I noticed that the first images is blurred during the time of the overlap, and then the second image is clear and does not loose quality.
I tried to apply a De-interlace filter but it just made the images look bad.
The two images are jpg format, 1087x751 and 770x1124
It seems like a simple procedure but I don't know what to do... Why do the images loose their quality? Even without using the transition, why does the image in V2 is blurred when overlapped with an image in V1. The second layer should not be affected from a lower one, no?
MANY THANKS

Welcome to the forum!
Did you render the two images (plus transition) fully before viewing? Check in the Sequence->Render menus to ensure all render types have a check mark beside them.

Problem with using two different apple IDs on the same iPhone 4s

my friend installed an app on my iPhone 4s using his apple ID. Then I created an apple ID for my own use. I then installed an app on my iphone. But, there's a pop-up box containing my friend's ID and asked me to put his password. How can i use my own apple ID?

All apps - all paid and free apps include DRM protection which is tied to the iTunes account that was used to download the app. In order to install an app update available for an app downloaded and installed with your friend's iTunes account will require using your friend's iTunes account and knowing your friend's iTunes account password.
If a paid app, this amounts to stealing. Delete the app that was downloaded with your friend's iTunes account and download the app with your iTunes account if an app you want.

Problem with loading two Javascript scripts

I loaded a dreamweaver widget called "twitter client" to pull user info from twitter. Problem is that it will not show up in the browser. I can get it to load and show, but only after I comment out the footer information. The footer is pulled externaly and calls on a Javascript hosted on another server. Here is the code showing the problem. I also loaded it to http://www.tempthirteen.com/template/. I am really at a loss as to what is causing it.
Thanks so much!!

Problem with connecting two computers with windows7 to the internet at the same time with wrt110

Me and my friend have both installed windows7 on our computers.
If one of us connects to the internet via wireless router WRT110 it goes without any problems.
But if we both try to connect to the internet at the same time, it doesnt want to connect.
Can anyone help?
Solved!
Go to Solution.

You can try upgrading/reflashing the router's firmware....Download the firmware from www.linksys.com/downloads and save it on the desktop....Login into the Linksys GUI and click on Administration tab...click on subtab "firmware upgrade" and choose the correct .bin file...click on upgrade....Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Now,press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

I have written a VI to send a series of commands called Cycle through Serial Port to a custom hardware. One of these commands is setting motor pressure by sending it's command and changing it's voltage. After setting desired pressure I have to read and control motor pressure, again through serial port in a parallel loop. There is a Pressure Sensor in system and I can obtain current's motor pressure by sending a command and receiving pressure value. In the first While loop I send some commands to hardware including Pressure Setting Command trough a state machine. In the second While Loop I read pressure value and then decide to increase motor voltage or decrease it. Now the problem is in communicating these two loops. In cycle after "Init" state when state reaches "Pressure 2 Bar" motor voltage will increase. Meanwhile I have to control this voltage in parallel While Loop. As you can see I used Local Variable to communicate between these two loops. The problem is that loops are not synchronized. Specially when I switch to "Pressure 3.8 Bar" state during cycle running control loop (second while) is still working based on "Pressure 2 Bar" state not 3.8 bar. Because of this motor pressure goes to 3.8 bar for a sec (becuase of "Pressure 3.8 Bar" state) and comes back to 2 bar (because the second while still has not gotten that new state,most probably cause of all the delays in the loop) and after couple seconds it goes back to 3.8 bar.
I really don’t know what to do. Is there a way to fix this? Or I should consider a better way to do this?
I went through Occurrence Palette but couldnt figure out how to embed that in the VI.
Sorry for my poor English. I attached VI and it's subVIs as a LLB file. I can explain more details if somebody wants.

I make it a point to NEVER have a WAIT function inside a state machine.
It sort of defeats the purpose, which I define as "Examine current state; decide whether you've met the conditions to advance to another state, then get out".
For example, I have a single state machine VI controlling four identical instruments, via TCP connections.
For some functions, that means issuing a command, waiting 60 seconds, then reading results.
If I waited INSIDE the state machine, then it's tied up waiting on one device and cannot handle any others.
Not a good plan.
To handle this, I have a loop which calls the state machine. After issuing the command, the state goes to "Waiting on Response", and there is a target time of 60 seconds from now.
It's called over and over in that state, and each time merely compares NOW to the target time. If NOW is past the target, then we read the results.
the state machine can tell the caller when to call back; that's how I distinguish between an urgent need and nothing-to-do.
By having the CALLER do the waiting, instead of the state machine itself, the state machine is free to handle another device, or do something else on the same device.
You should be calling the state machine over and over and over anyway. So, have the state machine "control the pressure" on every call, and THEN examine whatever state it's in.
