How can I put old albums into Photo Stream?
It used to be so easy to synch photos to my various devices: iPod touch, iPhone, iPad from my computer using iTunes. I could select the albums I wanted on each device, and there they were! But, iTunes now tells me that it no longer synchs photos. When I go to iPhoto and try to put old photos in the Photo Stream, it takes forever, and the photos in an album are all scrambled. It's like starting over. There has got to be an easier way -- what is it?
Web Galleries published in iPhoto are in the order that the web gallery albums are in iPhoto - if you drag a web gallery into a different position and sync the web gallery matches the order
I do not know how iWeb handles the order -- try web galleries and see how they work for you

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined

How to convert a string into a stream
Hi,
Actually, I have developed a small piece of code which is working well with the input from the User Console (Via System.in). The console input may be like 10 + 2. Now, I need to pass the input value through my code (Statically) while instantiate. What should i do?
The code is -
public static void main( String[] args )
throws ParseException, TokenMgrError, NumberFormatException {
EvalStr2 parser = new EvalStr2(System.in) ; // I need to pass my value as "10+2" instead of System.in
System.out.println("Result-->>"+parser.Start());
Waiting for your help.
Thanks
VenkateshWhy not simply provide EvalStr2 with an overloaded constructor that takes a String as a parameter?
Also, to learn how to ask a better question, read

Putting a ( String into a byte[] to send through a datagram)
I am making a program in java to send email in the form of an applet. I am not sure it is going to work but this is what I have so far:
import java.awt.*;

import java.net.*;
import javax.swing.event.*;
public class EmailSender extends JFrame
public void init()
//user types in email address
String recieveaddr = "";
JTextField emailaddr = new JTextField(15, recieveaddr);
//user types in his body of the email
String message = "";
JTextArea body = new JTextArea(50,50, body);
//user presses submit button to send email
JButton submit = new JButton("submit", emailaddr, body);
public void run()
try{
/*I chose to use Datagram for my method to send the email. I thought about Tcp. I might change my mind. I am not going to write down the source of what is supposed to go here. What I just want to do here is take the message and the email address and send it. I must know if there is a way to make a byte[] and write a String to it. If I know this I would be able to send the message with Datagram.*/

}I chose to use Datagram for my method to send the email. I thought about Tcp. I might change my mind. I am not going to write down the source of what is supposed to go here.

I will figure it out with the api after I download the seperate javamail package and the JAF. I was looking through the api for Java 2 Platform, Standard Edition (J2SE). Thanks for telling me about the javax.mail api. If you didnt tell me i'd keep looking through the wrong api and not being aware that I have to download a seperate package.

Process variable string into filename at Save service
Hello,
Does anyone know how to put a string into the Pathname Pattern (Template) property of a Save service (FileUtilsService - Write Document) ?
What I'm trying to do is strip the /'s out of a date string and put that date into a filename. For example, 042208_Greg.pdf
Instead I get d:\WMS\C0419\04\22\08\_Greg.pdf
I want: d:\WMS\C0419\042208_Greg.pdf
I have a Set Value service putting a form submit date (MM/DD/YY format) into a process variable called @stringDate. I am stripping /'s out of the date and setting @stringDate like so: /process_data/@stringDate <--- concat(substring(/process_data/xfaform/object/data/xdp/datasets/data/C0419/Approvers/Init iator/Date,1,2),substring(/process_data/xfaform/object/data/xdp/datasets/data/C0419/Approv ers/Initiator/Date,4,5),substring(/process_data/xfaform/object/data/xdp/datasets/data/C041 9/Approvers/Initiator/Date,7,8))
At the Save file service, I am using @stringDate in my Pathname Pattern (Template) to create the filename: d:\WMS\C0419\{/process_data/@stringDate}_{$/process_data/xfaform/object/data/xdp/datasets /data/C0419/Approvers/Initiator/CompletedBy/Name$}.pdf
Thanks,
Greg
Needham, MAHi Greg
You've done a great job getting this done with xpath.
It looks to me like you've done everything right - what's not working - are you getting an exception, or is the file being saved with the wrong name?
There is a nice little DateFormatter component here, that might make things a little easier/flexible.

Here it's easy to see. lol has not been initialized. You need lol = <something>;Usually <something> wil be new String[<some number>]but it could be a reference to an array you created elsewhere. -

Regards,
legendsinoYou need to convert the std::vector<std::string> into a sequence of bytes. For example, if all strings are shorter than 256 characters, you could create a fresh output string, iterator through the vector, and for each element, append the string length to the output string, followed by the string contents.
Note that ordering in the database will be different from lexicographic order, and you have to keep that in mind when performing range queries. -
How to put a String(date) into Date (java.util.date)??
hi there
I got a GUI here and I need to read some JMaskedTextFields from it. I put them all into Strings. Now I need to pass them to the search-function, but one of the search arguments is not string. Its Date. I tried to initialize Date with Date(String s) but he doesnt take it. Now Im asking how can I do this the easiest way?
The String has only digits and a . betwenn them, like this: 12.02.1978 and I want to pass this into the Date.
thx for helping :-)thx
Now I got it so far, it looks like this:
String datumVon = suchen_kriterien_datVon_JMaTextFeld.getText();
String datumBis = suchen_kriterien_datBis_JMaTextFeld.getText();
SimpleDateFormat formatter = new SimpleDateFormat ("dd.MM.yyyy");
ParsePosition pos = new ParsePosition(0);
Date datVon = formatter.parse(datumVon, pos);
Date datBis = formatter.parse(datumBis, pos);
System.out.println(datVon);
System.out.println(datBis);
The Problem is that he only makes the first print when both dates are given. If I only give him the first, so he prints the first. If I give him only the scond, so he prints the second. But when I give him both, he only prints the first!!! why? -

Copy from iPod to PC
It is important not to allow your iPod to sync with an empty library. If it is set to synchronise automatically you will get a message saying your iPod is linked to a different library and asking if you want to sync – it is important to press cancel as syncing with an empty library erases all music from your iPod.
You can also prevent auto sync by holding down shift & ctrl as you plug in your iPod and keeping the keys held down until the iPod appears in iTunes.
Once you are connected, you need to set your iPod to manage music manually.
http://support.apple.com/kb/HT1535
If you have an iPod with iTunes Store purchases on it, you can use it to copy your purchases to other authorized computers.
http://support.apple.com/kb/HT1848
However this is not allowed for other music.
This MacMuse tip tells you how to copy music from your iPod using Windows Explorer, but it is a bit fiddly:
http://discussions.apple.com/messageview.jspa?messageID=797432
Otherwise you can use third party software to manage the transfer, there are a variety of programs out there, some free and some that will copy ratings and counts as well as the music files. Here is a selection, check them out and see what suits you.

http://www.floola.com/modules/wiwimod/index.php?page=WiwiHome
http://www.ipodsoft.com/site/pmwiki.php?n=igadget.Homepage
http://www.copytrans.net/
For a more complete list see:

Does anyone know how to put strings into a vector here is my code to put some names of files into one.
Vector machines = new Vector();
String dir = "F:\\APPS\\SPCII\\DATA\\";
File directory = new File(dir);
machines.addElement (directory.list());
But when I print the vector, it only prints the address.
Thankslist() returns a String[] array. if you store it in an array, say
String[] dirlist=directory.list(); you can use dirlist.length and a for loop to enter the elements of the array one by one into the vector -
