How to show local filesystem view using Applet

hi all,
I want to display local filesystem view for file transfer using Applet.
Thanks.

Thanks for reply.
Actually I am able to display JTree of specified drive. For that I have created one class that implements TreeModel. But now I want to create a JTree containing listing of all the drives of Windows operating system.
Here is the code :-
private JTree               moFileTree;
private FileSystemModel moFileSystemModel;
     moFileSystemModel = new FileSystemModel(new File(System.getProperty("f://")));
     moFileTree = new JTree(moFileSystemModel);
This code gives the listing of f: drive.
And I know how to find out all the roots
     //To find out the all possible drives present on machine
          File aoFileRootDirs[] = File.listRoots();
          for (int iFile=0; iFile<aoFileRootDirs.length; iFile++)
               moFileSystemModel = new FileSystemModel(new File(aoFileRootDirs[iFile].getAbsolutePath()));
               System.out.println("file : "+aoFileRootDirs[iFile].getAbsolutePath());
But I want to create one JTree of all these roots.
Thanks.

How to pass data between views using Flex for mobile?

Hi,
In my 1st view, I have set of images. Each image represents a product category. When I click on an image, it has to show my 2nd view which is a list. This should show all the products linked to this category.
I saw few examples where the 1st view is a list. Select an item in a list shows the details in the next view.
But what I need is, I need to know which image is clicked in my 1st view (ie) Home page. This id needs to be passed to my 2nd view to retrieve the data for the clicked image (clicked product category).
Can anyone help me in this?

Chellaa2011,
If I understand you correctly, you can pass data to the next view by passing the second parameter to the pushView method.
check out: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/spark/components/ViewNa vigator.html#pushView()
I've written similar apps in the past and found that a singleton class alleviates some of these issues. If you use a singleton to track currently selections all your views can access the same data without having to pass and return data from each other.
Hope this helps,

HOW TO SHOW JLABEL IN JDIALOG USE TIMERTASK WHILE MAIN CLASS IS SLEEPING?

I have done a code below and it is working but the only problem is when the main program start to sleep by use Thread.sleep(10000) for 10 secs and it will prompt out a JDialog contain JLabel inside it with message "Please wait.... program is sleeping.". And when the thread ends the JDialog will auto disappear and it back to the main program.
The problem is:
When the JDialog appear, it doesn't show the component so I only be able to view the JDialog window without contain any component. I already use container to add the component into JDialog but it still doesn't show. I only be able to see the JDialog window contain empty component when the main window is sleeping.
How to make the components also appear in the JDialog when the main program is sleeping?
Below is the code pls have a try:

How do I remove images viewed using preview?

Hi, I'm new to this forum and not very computer savvy, so please bear with me if in the wrong place or asking dumb questions or using wrong jargon!
Still not quite understanding preview except that it seems the only way to see a bigger image of photo's I've added into PICTURES in Finder.
If I click on PREVIEW it takes me to a screen with an image I've previously viewed, then if I swipe again/repeatedly with 4 fingers more images on their own screens are seen as if I'm looking at a photo album. Most of these images I don't want anymore and have deleted them from PICTURES in finder but they are still in PREVIEW. There is no option (can't right click) or menu bar to delete or remove the images. When I right click on the PREVIEW icon I can see a list of the images/pictures I viewed but no option there either to delete. If I click on one, that one appears on a screen but the others don't disappear.
How can I remove the images I don't want to see/keep. And how can I choose the ones I do want to see.
Thank you for your patience and time

Hi Drew & Kilgore*
Thanks for your replies. I also have and use Simplenote, although I went off it for a while, when it started crashing all the time on me. It seems to be more stable again now, so I'll start using it more regularly again, perhaps.
I am, obviously, disappointed that one can't simply select ANY object within a Notes document and choose to delete it. As I rather suspected, the only solution is an annoying workaround. Apple stuff seems to get more like this as time goes by. At least in my experience.
I solved the issue my own way in the end, but I guess it was close to your 1st idea DR, and your 2nd option, KT: I basically cut and pasted everything above, and then everything below, the image, and pasted both chunks of text into a new note. So it took two passes, and left me with the original note just displaying the image, which I then trashed.
Tapping to the right of the image followed by deletion was what I hoped & expected would work. But instead the image stayed put and the text below the cursor would simply slide along the right hand side, moving upwards as I deleted! Most bizarre, to my mind at least.
Anyway thanks for the feedback. But, for anyone else that might want to know how to do this, the answer is: NO, you can't select and delete an image once it's in one of your notes!
* I quite recently watched the rather strange Bruce Willis / Nick Nolte 'Breakfast of Champions' movie... I think I still prefer the book to the film!

How to show classic package view in Acrobat 9?

In Acrobat 8, I had my package PDF with the left panel showing the PDF files, the middle panel showing the Pages panel, and the right panel showing the content of the page itself. With a three panel view, I could quickly navigate between PDFs, select a Page, and see the content. This is why I liked packages so much.
How do you create this classic package view in Acrobat 9?
Thank you for the feedback.

I am pretty sure the tool is still there. Adobe seems to enjoy moving the tools around, so try some of the other menus. If there is no forms menu there, try the advanced editing as the old location. It seems to have moved with every version.

How to show all data when using more than one parameter?

Hi All,
I used a query like this to show the data in a report:
select col1, col2 // col1 and col2 are columns of tabale tab1
from tab1
where
tab1.col1 =
(case when :P_COL1 IS NOT NULL then // :P_COL1 IS A USER PARAMETER TO EQUAL COL1
:P_COL1 ELSE tab1.col1
end)
AND TAB1.COL3 =
(case when :P_COL3 IS NOT NULL then // :P_COL3 IS A USER PARAMETER TO EQUAL COL3
:P_COL3 ELSE tab1.col3
end)
The problem is when I run the report with paramters values or not, It shows the data which is not null for both col1 and col3.
That is when the value of col1 or col3 is null the report would not return that record!
I want the report to show all data not only values which is not null!
How to do this?

Rainer,
That where clause will fail when col1 in the table is null and the parameter has the dummy value. Consider the following:
variable p_col1 varchar2
exec :p_col1 := 'yourdummyvalue';
select
from
     select 'yourdummyvalue' col1 from dual
     union all
     select 'other' from dual
     union all
     select null from dual
     union all
     select 'X' from dual
) tab1
where nvl(tab1.col1,'yourdummyvalue') = nvl(nvl(:p_col1,tab1.col1),'yourdummyvalue')In this case, the query returns the row with null and the row with 'yourdummyvalue', where only the row with 'yourdummyvalue' should be returned.
You must do something like this:
where ( :p_col1 is null or ( :p_col1 = tab1.col1 ) )That one is the simplest and does not need a dummy value. Here are some other more complicated examples:
where nvl( :p_col1, 'yourdummyvalue' ) = decode( :p_col1, null, 'yourdummyvalue', tab1.col1 )or this:
where nvl( :p_col1, 'yourdummyvalue' ) = nvl2( :p_col1, tab1.col1, 'yourdummyvalue' )In the last 2 cases, it will not matter if the dummy value exists in the data, but they are unnecessarily complex.

Here is a modified dealForm.jsp that merges the 2 steps - both symbol submission and Yahoo convert is done by it. Play with it and add your DB code to it:

<%
String symbol = request.getParameter("symbol");
if (symbol != null) {
String urlString = "http://finance.yahoo.com/download/javasoft.beans?SYMBOLS=" + symbol + "&format=ab";
try {
URL url = new URL(urlString);
URLConnection con = url.openConnection();
InputStream is = con.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line = br.readLine();
StringTokenizer tokenizer = new StringTokenizer(line,",");
String name = tokenizer.nextToken();
name = name.substring(1, name.length()-2);
String price = tokenizer.nextToken();
price = price.substring(1, price.length()-2);

How to show ok & cancel button using showMessageDialog

hi to all, when i use showMessageDialog it gives only ok option,
like
JOptionPane.ShowMessageDialog(null,"are you sure you want to continue" ,"Confirmation",JOptionPane.QUESTION_MESSAGE);
this statement shows only ok option, i want ok and cancel option both.
and can u tell me how to put actions in ok & cancel option
like if user clicks ok option then he can continue the program , if user clicks cancel then he would exit from the program.
can u tell how to comapre that using if statement
please reply me as soon as possible.

This is probably close to what you want. I believe messages can be replaced by null. You can probably figure out the rest from the API.
response = JOptionPane.showConfirmDialog(myFrame,
                                         messages,
                                        "Delete hard drive?",
                                         JOptionPane.OK_CANCEL_OPTION);
// If User hit CANCEL button we jump out
if (response == JOptionPane.CANCEL_OPTION)
    return;

How to show JSP Presentation without using tags

Hi,
is it possible to show JSP BI Presentation such as Thin Crosstab without using Presentation JSP Tag. Is there a method that renders Presentation (passes parameter of ThinDataviewCommon type and writes Presentation HTML) to output stream? Please give a sample code.
Slawek

Hi,
You can do this. Please look at the struts example code given (http://otn.oracle.com/sample_code/products/bib/content.html). Here a view is loaded in Struts Action class and stored in HttpSession. Then UIX renderer is used in JSP to access this object from HttpSession to render it.
Hope this helps

How to write file to server using applet?

Why didn't this work?

However, the reading from server is fine:

         links = (LinkHolder)inStream.readObject();
         inStream.close();
....I really appreciate for your help.
JTom

This file resides on server not local machine. I'm just testing on my local PC for now.
By the way, applet doesn't allow any kind of communication to client machine or others, but only to the server it resides in; according to the specs.
To get a url connection you need a server. You send
the output to the server(some servlet or similar
program running on server).
But for file you don't need a server. You can open a
file on your local machine if just have file
permissions. There is no server involved here.

How to show speed, when only using maps

Hi
I have a 5230, I will like to see the speed I am driving, only using map, but no destianation, is that posible and how.
Br/

Ah, depending on how new the car model is, the speedometer is more accurate.
Anyway, as of the moment Ovi Maps is incapable of doing what you're asking. However you can however simply put the navigation volume at 0, set a random destination and drive around. Just ignore the blue line in the navigation.
You do know where you are going, so why dont you just set that as the destination when you drive? I mean, that's what the Nav system is for right?
