Let's explain for me...Thanks

Dou you have a question ?
The character and string escape sequences allow for the representation of some nongraphic characters as well as the single quote, double quote, and backslash characters in character literals and string literals:'\b'     /* \u0008: backspace       */
'\t'     /* \u0009: horizontal tab */
'\n'     /* \u000a: linefeed        */
'\f'     /* \u000c: form feed       */
'\r'     /* \u000d: carriage return */
'\"'     /* \u0022: double quote    */
'\''     /* \u0027: single quote    */
'\\'     /* \u005c: backslash       */In case you are using Java 1.5, you might be interested in System.out.printf(), which usesformat string.

I am not doing it in ITunes, but i did down load the song from ITunes. I loaded the song on to my Nano, but in my menu selections it doesn't show the song or the artist in any search format. However, when i plug in my nano to my PC I see the Nano library on my PC drive listings and that song and artist are there. I can click on the song and it will play in Windows media on my work PC. I did notice that the format for most all the songs in my library on my Nano are MPEG - 4 audio Files.

Pierre,
You may try the list and see how far down you need to go; you have probably been through 1) and 2), and 4) is both reversible and more thorough than 3); 5) is hardly relevant, so you may end up with 6).
The following is a general list of things you may try when the issue is not in a specific file (you may have tried/done some of them already); 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
If possible/applicable, you should save current artwork first, of course.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to at least 5 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible);
5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall, run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.

Anyone have the problem I'm having with the Safari collecting cookies even when I'm not on a website? I cleaned everything out and checked several times. Each time cookies were added that I've never seen with my older version of Safari. I have the block third parties and advertisers but I don't think it works.

I have a problem when update tables with a database link (APEX)

Hi, I search answers for my problem and I not found a solution. My problem start when I open page with database link statement in APEX. I drop tables and execute this for update the tables in APEX.
EXECUTE IMMEDIATE 'CREATE TABLE XXXXXXX
AS
SELECT A1,A2,A3
FROM AAA@BBB';
I use Mozilla Firefox and isn't always updated the tables because it shows dialog for downloading file "f". I rename the file to txt and I see the text "IBMPC/WIN_NT-8.1.0"...
In the explorer always show a window only the text "IBMPC/WIN_NT-8.1.0"...
What is the solution for my problem? I need update this tables.
Thanks. John.

It's easy. It doesn't work a database link, on apex, with a pl/sql code or store procedure.
I saw that many people had the same problem but I don't see a solution.
As I put up, I want to remove my tables on APEX and copy the table of my Oracle database with the update dates.
The posts are from the same problem as my English is very bad, it got to help explain the problem.
I have a page with a pl/sql code. This code in Oracle is correctly.
For example, with this code I update the table PRUEBAS with the data of TABLEX.
BEGIN
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE "PRUEBAS"';
EXCEPTION WHEN OTHERS THEN NULL;
END;
EXECUTE IMMEDIATE 'CREATE TABLE "PRUEBAS"
AS
SELECT AAA,
BBB,
CCC
FROM TABLEX';
END;
But, in this code, I have the problem.
BEGIN
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE "PRUEBAS"';
EXCEPTION WHEN OTHERS THEN NULL;
END;
EXECUTE IMMEDIATE 'CREATE TABLE "PRUEBAS"
AS
SELECT AAA,
BBB,
CCC
FROM TABLEX@DB_LINK';
END;
I sometimes get an error. Sometimes it works fine, but half of the tries Apex returns "IBMPC/WIN_NT-8.1.0" in the browser and I am not using an IBM PC or Win NT...
And i read that In the alert_xe.log file there are a error of core dump... ... :S or that the application return corrupt headers.... Is a problem of versions?
I used a synonym and I have the same problem.
Even if I run the code on SQL COMMANDS (SQL WORKSHOP) it shows dialog for downloading file "f". I rename the file to txt and I see the text "IBMPC/WIN_NT-8.1.0"...
The problem is in Mozilla Firefox and in IE.
I have the OracleXE 10g (Application Express 3.0.1.00.08).
And the question is.. ... ... ... ... What is the solution? :)
Thanks.
John.

I have some problem about wifi sync with iOS5

Hi~everbody~
I have some problem with wifi sync, and still don't know how to resolve it. Please Help Me~
First,I using Windows 7 64-bit, the latest iTunes 10.5, and iPod touch 4 with 5.0(9A334), and of course a WIFI AP in my room.
Here is my major problem:
When I setted up enable wifi sync in iTunes summary, the iTunes had identified my iPod and show at left side in iTunes,
even when I unplug my iPod touch 4 from my computer, the iTunes still shows there.
But after one day when I came home, I opened the iTunes want do a wireless sync, but the iTunes did not found my machine.
I have tried restart computer, restart WIFI AP, disable anti-virus software, close MSN, close teamviewer, and any software may caused some unstable network issue between iTunes and iPod touch 4, but when I done these whole things, the iTunes still not found my iPod.
So I want to know do Wifi Sync needs any specific net port ? like 80 port or some port else?
Wish there are somebody can help me fix this, very appreciate.
BTW: Even iTunes did not found my iPod touch 4, but I can still using "Remote App" to control iTunes music play, so I really confuse why it just can't do wifi sync ?

This error has got nothing to do with rmi.
The StackOverflowError means the Java VM stack is filled up. The
stack is used for keeping track of method calls. An easy way to
produce a StackOverFlowErrer is the following code:
class Test {
public static void main(String[] args) {
a();
static void a() {
a();
So if you call method a() within the same method, the stack
fills up quickly.

Formatted output with JAXB

Hi, Please help me with the formatting of output XML file using JAXB. This is my client program that marshals xml content into xml file. This program is creating XML file with no indentation at all. I commented out the line
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
still getting same xml file with no indentation. Am I doing anything wrong?
Thanks in advance.
try {
// create a Validator
Validator v = jc.createValidator();
// validate the content tree
boolean valid = v.validate( root );
//logger.info("XML File Validated Successfully" );
Marshaller m = jc.createMarshaller();
m.setProperty(Marshaller.JAXB_SCHEMA_LOCATION, "http://mydomain.com/Schemas/data DT.xsd");
DataWriter writer = new DataWriter(
new OutputStreamWriter(new FileOutputStream(fileName),"UTF-8"),
"UTF-8" );
m.setProperty("com.sun.xml.bind.namespacePrefixMapper",new NamespacePrefixMapperImpl());
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
m.marshal(root, writer);
}catch( ValidationException ue ) {
logger.error( "Caught ValidationException"+ue ); throw new SdarsDBException("Validation Exception "+ue);
} catch( JAXBException je ) {

Hi,
try writing to the FileOutputStream directly.
I get formatted output this way.
maybe the DataWriter is doinfg some translatiopn for you?

Format output with printf

I'm currently taking a Java programming class using Java version 1.5.0_06 for my class.
I'm running into problems with the printf statements. Can someone help me figure out what's wrong with this statement?
outFile.printf("%-26s $ %12.2f%n", "Assessed Value:", assessVal);
Basically, I want the output to print, for example:
Assessed Value:********* $ 1000000.00 (* denotes spaces)
This is the error message I get when running it:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
The method printf(String, Object[]) in the type PrintWriter is not applicable for the arguments (String, String, double)
Any help is appreciated.

Well, opened list of arguments which is used by printf method, as well as autoboxing, are 1.5 features. So when you need to compile with an old java (1.4), opened list of arguments is replaced by array of Objects. And in this case you need to write something like
printf("your format string", new Object[] {"some string", new Double(varDouble)});But in this case you need to check what java version do you use to compile it. Just execute
java -versionYou can use -source argument to specify which version of java do you use (1.4 or 1.5) in your java sources.

Formatting output with colors

Hi,
I want to display a particular word with some color. But I have to choose that word at runtime based on some condition.
for eg: there are 3 words: str1, str2 and str3.
I have to print all the words, but str2 with yellow color and others with normal color ( ie no color ).
How to do this?
Regards,
Kalai

Hi,
Use the FORMAT keyword
eg.
FORMAT color 3.
write str3.
FORMAT color off.
Note :
FORMAT.
Additions:
1. ... COLOR n     [ON] or   ... COLOR       OFF
2. ... INTENSIFIED [ON] or   ... INTENSIFIED OFF
3. ... INVERSE     [ON] or   ... INVERSE     OFF
4. ... HOTSPOT     [ON] or   ... HOTSPOT     OFF
5. ... INPUT       [ON] or   ... INPUT       OFF
6. ... RESET
Effect
Sets or modifies the valid output format.
Notes
The formats set by FORMAT are effective from the next output operation to the list, i.e. from the next WRITE command or from the next new line.
The addition ON for switching on the relevant output format is optional.
You can also set the static additions ON, OFF and n (for COLOR) dynamically with = var (for further information, see end of this documentation).
Addition 1
... COLOR n [ON] or   ...COLOR OFF
Effect
Color of line background. n can have the following values:

Problems setting Inhibit Outputs with UMI

I am using a 3rd party stepper drive with a PCI7334 and 7764 UMI. The Step, Dir and Enable inputs on the drive are opto isolated. I have tied the -ve terminal of each to Ground and the +ve terminal to +5V though a 390ohm resistor and to the corresponding connection on the UMI.
I setup the axes inhibit output in software to be Inverting, the switch on the UMI is set to Active Low inhibit outputs and the Drives are Active closed (need to have a potential difference across them to be enabled).
My third axis must be enabled the opposite way around. But when i set it up in software to be Non-inverting, it doesn't change on the UMI. why would this be so?
Can you have one axis with its inhibit output active low, and another axis with it
s inhibit output active high?
Also, Do i need to pull the inhibit outputs high?
Your help will be much appreciated.

To whom it may concern:
Yes, you can have one axis with its inhibit output active low and another axis set to active high. You need to go into MAX under the Device Settings and expand the tree entitled Axis Settings. With the corresponding axis selected in the tree, you can set the inhibit output to active high or low. If you don't expand the tree under Axis Settings then whatever you set the inhibit output polarity to will apply to all axes on the board. That might be part of your problem.
That inhibit output shouldn't need to be pulled high. That would be handled internally to the board.
Hopefully that is help to you. Best of luck with things.

I have a problem to add data with UDO.

this is my code:
Try
            Dim oCompService As SAPbobsCOM.CompanyService
           oCompService = ap.oCompany.GetCompanyService()
           ap.oCompany.StartTransaction()
            Dim oDocGeneralService As SAPbobsCOM.GeneralService
            Dim oDocGeneralData As SAPbobsCOM.GeneralData
            ''in this line is the Error. ***
            +*oDocGeneralService = oCompService.GetGeneralService("MyDocUDO")*+
Catch ex As Exception
            If (ap.oCompany.InTransaction) Then
                ap.oCompany.EndTransaction(SAPbobsCOM.BoWfTransOpt.wf_RollBack)
            End If
   End Try
in this line trought a exception that it said: "Interface not registered". I think the problem is the object oCompService but I don't know solved. Anyone Can Help me??
Thanks.

...you are sure you have created the UDO "MyDocUDO" ? that error appears in the case that there is any UDO with that name, to verify if this UDO exists go in Business One to Menu Tools --> Customisation tools --> Objects registration wizard, in the wizard click next -> update existing object -> next : you will see the list of existing UDO....
I have verified that the object exists, even I have verified it in the table OUDO. I think that the error owes to the DLL SAPBOSCOM, but i don,t know solved it.
Thanks.
