How do I use multiple datasets?

Here is what I need to do. I need the user to choose a product via pop-up menu. When a product is chosen, data would load into another pop-up menu as to where (regions list - state/province) you can purchase the product. Once a location is chosen from that list this would then load data into a placeholder with a list of specific locations. Kind of similar to this http://labs.adobe.com/technologies/spry/samples/data_region/DataSetMasterDetailSample.html But how does this work? How does it call and load the other datasets? Thanks.

you can’t programmatically add messages/channels to an already existing task
So I can't create a task with more than one message, and I can't add a message to an existing task.
That sounds like I have to have a separate task for each message I want. That means separate READ operations at DAQ time. I hope the overhead doesn't cost too much (I'm doing a thousand other things at DAQ time).
I have an RT card in the system I'm designing. It's only using about 5% of the CPU time (PID controlling an engine). Will NI-CAN stuff work on the RT? How do I physically connect it? Is CAN just RS-232 at fast baud rates, or are there more electrical differences?

How can I use multiple row insert or update into DB in JSP?

Hi all,
pls help for my question.
"How can I use multiple rows insert or update into DB in JSP?"
I mean I will insert or update the multiple records like grid component. All the data I enter will go into the DB.
With thanks,

That isn't true. Different SQL databases have
different capabilities and use different syntax, That's true - every database has its own quirks and extensions. No disagreement there. But they all follow ANSI SQL for CRUD operations. Since the OP said they wanted to do INSERTs and UPDATEs in batches, I assumed that ANSI SQL was sufficient.
I'd argue that it's best to use ANSI SQL as much as possible, especially if you want your JDBC code to be portable between databases.
and there are also a lot of different ways of talking to
SQL databases that are possible in JSP, from using
plain old java.sql.* in scriptlets to using the
jstlsql taglib. I've done maintenance on both, and
they are as different as night and day.Right, because you don't maintain JSP and Java classes the same way. No news there. Both java.sql and JSTL sql taglib are both based on SQL and JDBC. Same difference, except that one uses tags and the other doesn't. Both are Java JDBC code in the end.
Well, sure. As long as you only want to update rows
with the same value in column 2. I had the impression
he wanted to update a whole table. If he only meant
update all rows with the same value in a given column
with the same value, that's trivial. All updates do
that. But as far as I know there's know way to update
more than one row where the values are different.I used this as an example to demonstrate that it's possible to UPDATE more than one row at a time. If I have 1,000 rows, and each one is a separate UPDATE statement that's unique from all the others, I guess I'd have to write 1,000 UPDATE statements. It's possible to have them all either succeed or fail as a single unit of work. I'm pointing out transaction, because they weren't coming up in the discussion.
Unless you're using MySQL, for instance. I only have
experience with MySQL and M$ SQL Server, so I don't
know what PostgreSQL, Oracle, Sybase, DB2 and all the
rest are capable of, but I know for sure that MySQL
can insert multiple rows while SQL Server can't (or at
least I've never seen the syntax for doing it if it
does).Right, but this syntax seems to be specific to MySQL The moment you use it, you're locked into MySQL. There are other ways to accomplish the same thing with ANSI SQL.
Don't assume that all SQL databases are the same.
They're not, and it can really screw you up badly if
you assume you can deploy a project you've developed
with one database in an environment where you have to
use a different one. Even different versions of the
same database can have huge differences. I recommend
you get a copy of the O'Reilly book, SQL in a
Nutshell. It covers the most common DBMSes and does a
good job of pointing out the differences.Yes, I understand that.
It's funny that you're telling me not to assume that all SQL databases are the same. You're the one who's proposing that the OP use a MySQL-specific extension.
I haven't looked at the MySQL docs to find out how the syntax you're suggesting works. What if one value set INSERT succeeds and the next one fails? Does MySQL roll back the successful INSERT? Is the unit of work under the JDBC driver's control with autoCommit?
The OP is free to follow your suggestion. I'm pointing out that there are transactions for units of work and ANSI SQL ways to accomplish the same thing.

How Can I Use Multiple Weblogic Instances in a Single OS

Hello Everyone,
Actually I have to install Some different applications. Few of them need weblogic 10.3.6 and others need 10.3.4. The OS am using is Oracle Enterprise Linux 5.
Now I am able to install 2 separate(One of 10.3.4 and 10.3.6) instances with two different users,In two different directories.
I have installed the weblogic 10.3.6 version with a user webadmin and installed node manager with port 5556. This is working fine.
The main problem here is :
In the second instance (10.3.4 ) installed with a a different user and gave the port number to NodeManager as 1600 and its not getting started. Its throwing error and also after some errors in the terminal am able to see that its reverting to port number 5556 only.
What might be the issue?
I have to install 2 different versions of weblogic in a single Server. But am failing with NodeManager. What Can I do to have multiple weblogic instances with multiple versions in a single server ?
Can anyone suggest a resolution for this please ?
Thanks in advance.

How can we use multiple transactions by using bdc_insert.

HI
How can we use multiple transactions by using bdc_insert.

Hi,
In between the Open and Close we have to use the BDC_INSERT for the Tcodes you have to do.
BDC_OPEN_GROUP
BSD_INSERT
TCODE = tcode1
BDC_INSERT
TCODE = tcode 2
BDC_CLOSE_GROUP
check the SDN for more on this.

How do I use multiple addresses at one time?

Shouldn't the Adobe server page that allows for the entry of a recipients address tell users how to add another address? Do we separate them with semicolons? Commas? Or is it even possible to use multiple addresses?

Yes, Adobe Send.
Unfortunately, it is NOT spelled out on the page where you enter email addresses of recipients, nor is it revealed if you click on the question mark box by email address.

How do I use multiple accounts on the same Mac with Apple TV2?

I have home sharing turned on in two separate accounts on a single MacPro. When I am logged into both accounts, I can see both accounts' iTunes Libraries available in the AppleTV2. However, when I try to open each account iTunes Library in the AppleTV2, only one account will open (whichever one I logged into first). (In other words, I log into Account1 then open iTunes with Home Sharing On, then log into Account2 (while Account1 is still logged on), open iTunes with Home Sharing On. AppleTV2 shows Account1 Library and Account2 Library under Computers, but will only load Account1 Library. Account2 Library will just cause AppleTV2 to search for the Library then give an error.) How come AppleTV2 can see both Libraries but will only open one Library? How can I fix this?
Thanks,
zpockets

Thank you for replying. Both of the accounts are Admin accounts. The Libraries are kept in the user/music/itunes/itunes media folder on each account. However, I do use multiple iTunes Libraries on my Account1. One of the Libraries I use in Account1 is on a separate internal HD. However, the other Libraries I use in Account1 are stored in user/music/itunes/itunes media folder on the main HD (which hosts both Account1 and Account2). It doesn't seem to matter whether I am using an iTunes Library on an external drive or the main drive in Account1, I still get the same problem: only account1 library will load. AppleTV sees that the Account2 Library is there, but it won't load it.

How can I use multiple icloud Accounts with Fotos?

Hello.
Yesterday, my wife and I started using the new App "Fotos" on OSX and iOS.
What I can't figure out, and where I would like to get some insight and help, is how we should use our icloud Accounts.
How it is right now:
- Wife (MacBook and iPhone)
Has her own icloud-Account ([email protected]) for Backup (iOS) and Fotosync, Keychainsync, Bookmarks. 20GB iCloud-Account (18GB free).
- Husband (MacBook, Mac Mini and iPhone and iPad)
Has his own icloud-Account ([email protected]) for Backup (iOS) and Fotosync, Keychainsync, Bookmarks. 20GB iCloud Account (10 GB free).
- Husband has about 400 GB of Photos from over 10 Years on Mac Mini
How I want it to be:
- Husband
upgrades to at least the 500GB Account, to use for all 400GB of Photos and Backup, Keychainsync, Bookmarks.
- Wife
Has her own Account ([email protected]) for Keychain and Bookmark, but uses [email protected] on MacBook and iPhone for Backup an Fotosync, so that all Photos are stored in a single one family "container". All Photos in one Place without being able to forget to put them there.
I don't see, how I can accomplish that, since only one "real" icloud account seems to be possible in iOS, so that if i put my account in her iPhone I would get the Photo and Backup I want, but she would not be able to sync her own bookmarks an keychain any more.
Any thought on how to resolve this?
Am I missing something?
Thanks for your ideas,
thomas

Yes, you could have multiple iCloud accounts for Mail, Contacts, Calendars, Reminders, Safari, Notes, and Find My iPhone, but only one primary iCloud account for Photo Stream, Documents & Data, and Storage & Backup.

How do you use multiple displays with a MacBook Pro and iMac

I have an iMac and a MacbookPro laptop both upgraded to OS X 10.9 (Mavericks). I'd like to use multiple displays with them. Can I do this without an Apple TV? They are both on the same network. If I can, can someone please give some instructions on how this can be done?
Thanks!

Both computers have ports for external monitors. Check your user manuals. Only one display can be added to the MBP, but newer iMacs have dual Thunderbolt ports.
Do your own Google research to learn what to do, but reading your manuals should be all you really need. It' not rocket science yet.

Pls tell me how to use with example
Thanks & regards

This what i am trying to do man but i have little bit problems Pls give some solution with good example
And my coding is
declare
     emp_code varchar2(25);
in_time varchar2(25);
out_time varchar2(25);
Cursor P1 is
Select REASON,ECODE,READMODE,EMPD,ENPNO,FILL,PDATE,PTIME,INOUT,CARDN,READERN

group by REASON,ECODE,READMODE,EMPD,ENPNO,FILL,PDATE,PTIME,INOUT,CARDN,READERN
ORDER BY enpno,pdate,ptime;
begin
     for r2 in p1 loop
declare
bar_code varchar2(25);
begin
select barcode into bar_code from dail_att where empcode=r2.enpno and attend_date=r2.pdate;
For r3 in (select empcode,empname,barcode,intime,intrin,introut,addin,addout,outtime,attend_date from dail_att)loop
if r2.inout ='O' then
update dail_att set outtime =(select max(r2.ptime) from temp_att where empcode=r2.enpno and barcode=r2.cardn and attend_date=r2.pdate group by r2.cardn,r2.enpno,r2.pdate );
end if;
end loop;
exception
     when no_data_found then
     if r2.inout ='I' then
               insert into dail_att(barcode,empcode,intime,attend_date)(select r2.cardn,r2.enpno,min(r2.ptime),r2.pdate from temp_att group by r2.cardn,r2.enpno,r2.pdate );
     end if;
end;
end loop;
commit;

With Pages 5.2 how can i use multiple language types in a single document

My Macbook Air Has the version 10.9.3
I'm used to work with the old version of Page.
But now I am using the new version of Pages 5.2 (1860).
I want to know with the new version how do I use an multiple language types in a single document option.
In the old version of Pages I was using Inspector -> Text -> "More" tab -> Language: British Inglese.
In the new Pages 5.2 I do not know how to do it
Could you help me?
melo

It's not possible to tag text with multiple languages in Pages 5. Go back to Pages 4, which should still be in you iWork folder.
For the whole doc in Pages 5, use Edit > Spellling and Grammar > Show Spelling and Grammar.

Using Multiple Datasets and Spry in DW CS3

Hi there, I am currently trying to get an XML file pushed
into a HTML page by using Spry in Dreamweaver CS3.
However it uses three datasets. The schema is like this:
funds-and-headings
----> properties+
------------> region
------------> reference
------------> known-as
------------> funds+
---------------------> type
---------------------> heads+
-----------------------------> description
(where there is a + this means a heading)
but I am struggling to pull in the data.
If I highlight 'properties' I can pull in the first 3 records
but funds gives an 'unspecified' error message.
I just want to know how I can then pull in the other fields
all into one line and return all the results from the XML.
Any hlep most welcome and sorry if I missed anything out that
would help.

Thought I'd drop a url so that my issue is more clear. :)
This is in Alpha, but a url would be:
http://center4spine.com.s11267.gridserver.com/how_we_help/spinal_decompression/
. You'll see the categories on the left; clicking a title changes
the content on the right. The first category's content is displayed
initially. I need to be able to link directly to the FAQ. How do I
get that page to show up with the FAQ loading first via a
hyperlink? I hope that's more clear!

How do I use multiple librarys to organize my projects

Is there a way to use multiple libraries to organize my projects. I don't like having all my projects in one library. I'd like separate libraries for Family_Movies, BirthdaysandHolidays, Vacations, etc...
Thanks.

You can create multiple folders in your Project Library. I have a folder for each year. Then within the year, if I make several videos on one subject (say a trip to Europe) I will create sub folders within the year.
There is no limitation on what you name your Folders, so you could name them Family Movies, Vacations, Birthdays, etc.
When you are in the Project Library View, you can click FILE/NEW FOLDER. For a subfolder, click on the parent folder and then click New Folder.

How do I use multiple VPP accounts in a school system with 1 Profile manager server?

I have 40 schools with their own money they want to spend on apps. I need these accounts to be seperate. We are registered in the Device enrollment program and are using Apple's profile manager to distribute VPP apps. In the DEP website you can add existing vpp admins. I had hoped when these accounts purchased apps, the apps would show up in Profile Manager which uses the master Apple ID, but this didn't happen. Anyone know what the correct process is for doing this?

If you haven't found the answer: You have to install the correct token for each account. Apple Servers, as far as I know, do not support using multiple tokens at once. As a result, you will have to swap out each of the 40 tokens anytime anyone wants to buy something then assign it to a user then push the app.
Or just buy it with a redemption code and give that code to your users.

How can I use multiple constructor

Hi,
I have some problem to using multiple constructor in java. It shows some error while compiling the following program. can any one give better solution for me.......
public class Test6{
public Test6(){
this(4); /*
C:\Test6.java:5: cannot find symbol
symbol : constructor Test6(int)
location: class Test6
this(4);
Test6(byte var){
System.out.println(var);
public static void main(String[] args){
Test6 t6 = new Test6();
}

A number like 4 is an integer literal. So, you are passing an int to a function that is defined to accept a byte, hence you have a type mismatch. You need to cast the integer literal to a byte before passing it to the function:
this( (byte) 4);
