How to bild a graphical wizard in the most proper way?

In some applications there are wizards for creating different things. How are the graphical wizards constructed?
Let´s say there is a two-step way for creating a Person object. In the first step, you have to add some personal information. Then you click on the Next button to get to step 2. If you move the window of step 1 to a another location on the screen and then press the Next button to get to the step 2, then the step 2 window appears at the location of the step 1 window.
Is the most common way to build such a wizard to create JDialogs where the last dialog gets the location coordinats of the previous JDialog?

How are the graphical wizards constructed? a frame/dialog containing a cardlayout JPanel (at BorderLayout.CENTER)
the cardLayout panel contains:
1) a JPanel for 'step1'
2) a JPanel for 'step2'
3) a JPanel for 'step3' (if required)
etc.
next/prev buttons are added to the frame/dialog's BorderLayout.SOUTH,
and are disabled if/when there is no next or previous screen

Hey. anyone knows how to synchronize the different sounds in a song the most easy way?

hey. anyone knows how to synchronize the different sounds in a song the most easy way?

Play better... just kidding. Set an appropriate quantize value for all the regions in the inspector window. If you are doing live playing and need to synch to that it is MUCH more complicated. If you're new at this it might actually be easier to re-play it.

What is the most reliable way to run one Windows accounting program in Osx 10.5.8?

I have a simple Windows application where I basically do my accounts. I do not want to tie up my Imacs resources with running a full Windows Os "emulation" like Paralells or VMware Fusion just to run a simple accounting program.
I have heard about apps that can run one windows application at the time through a kind of Osx Application which emulates windows some how. Is is true that this is a better way of running my accounting program? Is it reliable? What I do is to punch in invoices and print out reports basically. How much resources does this "consume" to run it in "one simple application mode" in comparison with for example Paralells?
And what is the term for running windows in "one simple application mode"?

I guess you could try the free trial of CrossOver. http://www.codeweavers.com/products/crossover/ You did not say what app you want to run so it is difficult for us to recommend crossover as being able to run the app.
But your question is that you are looking for the "most reliable" way to run a Windows program. In my opinion you need Parallels or Fusion. These run the real Windows OS so my thinking is it is the "most reliable" method of running a Windows app on an Apple computer, other than Boot Camp.
But you said you don't want Parallels. This is probably why you have not received any responses. You eliminated the most reliable and easiest method, in my opinion, when you initially posted. Parallels does not consume any resources until you start it up to use your app. You can close it after you are done with your app. Of course hard drive space is required for storing the OS, your app, and data. But you still need to store your app and data regardless of method you choose.
One more thing, Parallels and Fusion create a virtual machine for running Windows.
So my recommendation, use Parallels or Fusion.

The most effective way from varchar2 to CLOB?

this is my table's TAB structure on Oracle 10g r2:
TAB_ID (PK),
TAB2_ID (FK constraint to TAB2(TAB2_ID), index created),
TEXT varchar2(4000)
What is the most effective way to convert varchar2(4000) column to CLOB column?
1. create new table TAB_NEW with column TEXT as CLOB,
then insert /*+ APPEND */ into TAB_NEW SELECT * FROM TAB,
then rename table TAB to TAB_OLD,
then drop constraint and indexes
then rename TAB_new to TAB
then add constraints primary key and foreign key,
then add index on TAB2_ID
then drop table TAB_OLD
OR
2. rename column TEXT(varchar2) to TEXT_OLD
then add column TEXT(type CLOB)
then update(how the most effective?) TAB set TEXT=TEXT_OLD
drop column TEXT_OLD.

1 will work, as you can assign a VARCHAR2 to a CLOB and Oracle will convert it.
2 is redundant.

What is the most efficient way to convert a static site to a responsive site using Dreamweaver?

I need to convert an old site made in Dreamweaver to be responsive to any monitor size. What is the most efficient way to do this?

Depending on what you have to work with and how it was coded, it might be doable and then again not. Suffice it to say, there are no magic buttons that will do this for you. Also consider that mobile & tablet users interact differently with their web devices. So your navigation & forms must be finger friendly. Also images & content must make mobile users happy without killing their dataplans. There's a lot of planning that goes into making a good Responsive Web site.

What is the most efficient way to post several stories to multiple html pages

What is the most efficient way to post five stories to multiple html pages?
Currently they are all html files saved in DW with some divs sharing content and other divs are unique.
I've experimented with saving stories as library items and dropping into other html but wondered if there is a more efficient or dynamic process.

I have an ipod classic with 4gb, it is full. What is the most economical way to upgrade to at least 16gb?
(I don't want to delete anything)

To recover the photos from an iPod Classic you'll need to use third-party software and the photos gained will be quite low resolution.

The most efficient way to search a large String

Hi All,
2 Quick Questions
QUESTION 1:
I have about 50 String keywords -- I would like to use to search a big String object (between 300-3000 characters)
Is the most efficient way to search it for my keywords like this ?
if(myBigString.indexOf("string1")!=1 || myBigString.indexOf("string2")!=1 || myBigString.indexOf("string1")!=1 and so on for 50 strings.)
System.out.println("it was found");
QUESTION 2:
Can someone help me out with a regular expression search of phone number in the format NNN-NNN-NNNN
I would like it to return all instances of that pattern found on the page .
I have done regular expressions, in javascript in vbscript but I have never done regular expressions in java.
Thanks

Answer 2:
If you have the option of using Java 1.4, have a look at the new regular expressions library... whose package name I forget :-/ There have been articles published on it, both at JavaWorld and IBM's developerWorks.
If you can't use Java 1.4, have a look at the jakarta regular expression projects, of which I think there are two (ORO and Perl-like, off the top of my head)
http://jakarta.apache.org/
Answer 1:
If you have n search terms, and are searching through a string of length l (the haystack, as in looking for a needle in a haystack), then searching for each term in turn will take time O(n*l). In particular, it will take longer the more terms you add (in a linear fashion, assuming the haystack stays the same length)
If this is sufficient, then do it! The simplest solution is (almost) always the easiest to maintain.
An alternative is to create a finite state machine that defines the search terms (Or multiple parallel finite state machines would probably be easier). You can then loop over the haystack string a single time to find every search term at once. Such an algorithm will take O(n*k) time to construct the finite state information (given an average search term length of k), and then O(l) for the search. For a large number of search terms, or a very large search string, this method will be faster than the naive method.
One example of a state-search for strings is the Boyer-Moore algorithm.

What is the most effective way to write Statement to catch and reverse errors during query excution?

Hello my friends:
I am wondering what is the most effective way to deal with errors, specifically in a
Stored Procedure.
I wrote something like this:
BEGIN TRY
BEGIN TRANSACTION
/*My statements goes in here*/
IF ERROR_NUMBER() = 0 -- Do I need this line?
COMMIT TRANSACTION;
END TRY
BEGIN CATCH
IF ERROR_NUMBER() > 0 --Do I need this line?
ROLLBACK TRANSACTION;
END CATCH;
It would make sense using the if Statement when attempting to log errors.
Just too many variations.
Thanks

What is the most efficent way to create both a standard and HD DVD

Hi,
I'm just getting into HD video editing, and I have relatives who will be several years behind me. I will be making HD DVD's for myself to use, but I will also need to make standard DVD's to send to my relatives.I am assuming that the HD DVD's I create will not play in a standard DVD player. I may be wrong. However, If this is correct, is there a particular point in the process of working with Encore where I can make that choice, create the DVD, and then go back and alter it in order to create the other type without destroying and having to redo everything that was done up to that point?

Thank you Hunt. Being ahead of most of the rest of the world and getting the best technology out there can be a pain sometimes. Reading through Jon Geddes' article left me scratching my head several times, and some of it went way over my head, but I'll keep at it, until it sinks in. Some language, terms, and shorthand, I'm sure are simple to understand to a lot of people, but I'm not in that catagory. I'll just keep working at it.

Subject: what is the most efficent way to create both a standard and HD DVD
I would edit the Project in HD in PrPro. The BD authoring part will be straight workflow.
For the SD DVD-Video, you have a few choices. You can Export to DV-AVI Type II for Import into a new Encore Project for the DVD. Some feel that PrPro does not do a good job at down-rezing from HD to SD. For a workflow that will likely yield better quality, see this http://www.precomposed.com/blog/2009/07/hd-to-sd-dvd-best-methods/. If you have PrPro/Encore CS4, then Jeff Bellune's /thread/487134?tstart=0 might be useful to you. Just follow the links to the tutorial.
Good luck,

The most compatible way of offering short movies on a website?

Hi everyone,
I am working on a website which offers links to short movies
which the admin has uploaded. they are in mwv/mpg/avi format. I am
using this object method, I can see them on my systems, but the
client cannot make it to work on their systems. I am looking for
the most compatible way of linking and displaying short movies on
the site. work with PC and mac.
this is my current method that apparently is not fully
compatible:
<cfoutput><embed src="Media/#MediaParam#"
width="408" height="354" autostart="1"
showstatusbar=1></embed></cfoutput>
any help is appreciated in advance..

can the data go from the drive direct to the ATV2?
no.
iTunes must be running to fetch and serve the content to ATV.
I ask as its far easier to connect a ATV2 and a Network drive via cat5, however itd be nice to not have to plug a mac in as well.
if your wireless network is n-capable and doesn't suffer interference problems, that scenario might work.
Possible try to get a older ATV?
good luck with that they are hard to come by. try eBay or something.

What's the most efficient way to transfer to personal domain?

I've been using the cumbersome .Mac address and have spent a lot of time optimizing the site, having also purchased a domain name (which I'll switch to), which is currently masked and forwarded. So what's the most smooth way of using the personal domain without losing all the strides I've made to get bumped up in the rankings? Thanks in advance for your suggestions. www.RedCottageInc.com (that's my future personal domain!)

I'm saying that you give Google the .Mac URL to get to your sitemap but use the registered domain name for normal access.
You are promoting your site with www.RedCottageInc.com but, because it is masked, Google needs your web.mac address to access the verification file and the sitemap so that it can spider your site.
You normally upload your sitemap as "sitemap.xml". You can test its accessibility by entering
http://web.mac.com/username/WebSiteName/Sitemap.xml in your browser.
Google needs this URL to get to the sitemap - visitors will use www.RedCottageInc.com.
Google wants to get to the verification file and the sitemap but your website visitors don't.
I guess all this is confusing if you haven't done it before and I don't know that I am explaining it very well. The best way to get it is to go through all the steps of creating the verification file and sitemap, uploading them to your site folder and adding and verifying in your Google control panel.

What's the most efficient way to serve a file from a servlet?

I have a servlet that does various different things depending on the needs. Sometimes it dynamically generates content, and sometimes all it does is send a file out, with no alteration.
What is the most efficient way to just send a file?
One option:
OutputStream os = response.getOutputStream();
InputStream is = new FileInputStream(...)
(send all the bytes from is to os, the regular way using a buffer)Another option is to say:
RequestDispatcher rd = response.getRequestDispatcher(fileName);
rd.forward();Any other options? What's the prefered way of doing this?
I know the rule of "don't optimize too early" but this is a situation where we need to get the maximum amount of files served with the hardware we have, and it's going to be a lot of static files, so efficiency is important.
Thanks

Ok, that's what I thought. It would be nice if there were a "response.sendStream(InputStream input)" method in the ServletResponse class. Even nicer would be a sendFile or sendChannel or something. This is probably a common usage and it's a place where the container has many opportunities for optimization. For example, it could call the operating systems send_file kernel call so the entire transfer would be done directly from the disk controller to the ether card (on systems that support that).
For now I'll just do my own buffered copy.

What is the most efficient way of passing large amounts of data through several subVIs?

I am acquiring data at a rate of once every 30mS. This data is sorted into clusters with relevant information being grouped together. These clusters are then added to a queue. I have a cluster of queue references to keep track of all the queues. I pass this cluster around to the various sub VIs where I dequeue the data. Is this the most efficient way of moving the data around? I could also use "Obtain Queue" and the queue name to create the reference whenever I need it.
Or would it be more efficient to create one large cluster which I pass around? Then I can use unbundle by index to pick off the values I need. This large cluster can have all the values individually or it co
uld be composed of the previously mentioned clusters (ie. a large cluster of clusters).

It sounds pretty good the way you have it. In general, you want to sort
these into groups that make sense to you. Then if there is a
performance problem, you can arrange them so that it is a bit better for
the computer, but lets face it, our performance counts too. Anyway,
this generally means a smallish number of groups with a reasonable
number of references or objects in them. If you need to group them into
one to pass somewhere, bundle the clusters together and unbundle them on
the other side to minimize the connectors needed. Since the references
are four bytes, you don't need to worry about the performance of moving
these around anyway.
