How to use thread only for progress bar.....

Hello,
I am working on an application which is taking time to load. Now I want to use a progress bar to tell the user of the application that It is taking time to load. How to do it... I read the Java swing tutorial and went through the example. Please tell me what to do. Because I am unfamiliar with Threads and I am not using thread anywhere in my application.

You are using threads. All Java execution occurs on threads. Write a Java GUI and you're in a multithreaded environment - there's no way out of that.
If your "application is a complex one" then you would be better advised to understand threads than to try and pretend that they don't exist. For a start, if you don't think you're using threads then you're destined to run in to all sorts of problems as regards an unresponsive GUI, as you're probably now finding out.

Hi,
Take one integer value attribute in the context of view
when you r performing action on POP1 set it's value to 1
when you r performing action on POP2 set it's value to 2
create one method which receives integer argument, say diaplay(int a)
In the action call display(wdContext.currentContextElement().get<intvariable>()) by passing the value in the context attribute
in display() method, Check the value of integer variable..
if it is 1 then perform action related to POP1
if it is 2 then perform action related to POP2

How to use Web Serivce for not jsr 172 phone

Hi:
Is anyone know, how to use web service for phones that only have standard J2ME package installed (without jsr 172 web service packagenstalled)?
thank you

Hi,
I think you need to write the code for this from scratch (built on top of existing HTTP functionality). There may be open-source J2ME code you could use. I've never tried this so I'm afraid I don't know any more. But maybe that is what you were asking... i.e. does anyone have code that does this already...

GSX, if you're referring to Apple's service by that name, is available only to employees of Apple-authorized service providers or self-servicing accounts. Unless you are employed by such an organization, you cannot access GSX. If you are employed by such an organization, they should set you up and give you the appropriate login information.
If you are interested in becoming a certified Apple hardware technician, you can find information here:
http://training.apple.com/certification/acmt
Please note, though, that certification does not in and of itself give you access to any of the Apple resouces for support organizations; diagnostic tools, parts ordering, etc. You again must be employed by an authorized Apple support provider before you can gain such access.
I have no idea what "knowlaged" might be.

How to use threads in JSP???

hello
i want to use threads with JSP.
i want to write a jsp page which will
start 2 different threads. the 1st thread should just display a message and the second page should redirect this page to another jsp page.
till the redirection is goin on, the message should be displayed in the browser from the 1st thread.
i dont know actually how to use threads in JSP by implementing the Runnable insterface, if not m then how do i do it ??
thanx
Kamal Jai

Why do you want to use threads to do this ??
If you write a message and do a redirection, the message will be displayed until the other page will be loaded into the browser...
I already launched a thread from a JSP but it was for a four hour process where the user can close his browser windows.

How we use Surrogate Keys for snowflake dimension

Hi All,
my question is - How we use Surrogate Keys for snowflake dimension
i heard from some body Surrogate Keys only work with star schema.
please correct me if i wrong.
Regards,
Manish

Hi manishcal16PPS,
According to your description, you can only create natural key in your dimension. But it's not working when using surrogate key. Right?
In Analysis Services, the snowflake schema of the dimensions are represented by more than one dimension table in other words its takes multiple dimension tables to define a dimension. Surrogate key are just some extra, redundant, unique key based on the
natural key. So there's no direct relationship or some limitations between surrogate keys and snowflake schema.
In this scenario, since there's relationship between the two dimensions, you should create natural key. For using natural key or surrogate key. Please refer to an article below:
Surrogate Key vs. Natural Key
For understanding star/snowflake schema, please see:
Understanding Star and Snowflake Schemas

I have a pc that is one year old and the hard drive is crashing we use it only for quick books to run our small business I would like to buy a macmini and install the OS from the pc to the apple product i will not use the pc after, can i use the OS off the pc or do I have to purchase another?

I think you can get Windows 7 for around $99. Install the 64bit version as the 32bit version will not be able to use all your new computer's ram if you have more than about 3.5gb.
Back up your quick books data now before the old hard drive dies. You can copy your data over to your new installation of Windows and quick books.
By the way, there is quick books for Mac http://quickbooks.intuit.com/mac/?sc=BNR-000-COR-quickbooks&priorityCode=4902000 000&cid=ppc_google_QB-Intuit-Core-Brand-Mac_quick-books-for-mac_exact&site=&ad_i d=9347918288&raw_keyword=quick%20books%20for%20mac
So you may not need to install Windows at all.
