Making custom icons with transparency, and Cover View mode

I tried making a new icon for a folder, and transparency doesn't seem to be treated the same in Leopard as it was in Tiger.
Trying to get an object to float onscreen, without a square white background, I tried pasting the following onto the folder's icon at the top of a Get Info window:
1. one layer of a .psd file
2. the image Saved For Web in Photoshop (as a GIF), open in Photoshop
3. the same image saved as a .png, opened in Photoshop
4. a Photoshop EPS with a clipping path, opened in Photoshop
5. the GIF file opened in Preview
6. the .png file opened in Preview
the results:
1. the transparency surrounding the object comes out as white
2. a speckled, purple image with a white background
3. the same as 2
4. the same as 1
5 and 6: the transparency seems to work: the icon on the
Get Info window loses its white background and the icon floats correctly on the Desktop. But in Cover Flow viewing mode, it completely disappears.
What am I missing? By the way, the icons for the image files, in Cover Flow, show the white background for the .psd and .png files, but not for the .gif, where the transparency shows correctly. The .gif's icon seems to show the image with a white background in List and Icon view, but only the generic GIF icon in Column view. This all seems strange to me.

I think you probably discovered the Cover Flow Bug. See this thread and the older one referenced in it as well:
http://discussions.apple.com/thread.jspa?messageID=6846850
As for the rest, well, at least you can copy something with a transparency out of Preview and paste it as an icon. Preview and Photoshop seem to me to not play well together with transparencies. I've gotten some VERY strange looking things, going back and forth between them with pngs and tiffs. Don't use gifs, or eps files, but I did notice that Finder does a rotten job coping with Photoshop's alpha channel (especially weird since once upon a time it worked fine, ditto for being able to show thumbs for eps files).

How to use/create icons with transparent background ?

I would like to use icons with transparent background on JButtons, but I can't find how to do it. Until now, I've been using the ImageIcon class to create icons from GIF images. These images were created with MSPaint (sorry, I don't know what I could have used instead of that). Here is how I create my buttons :
bPencil = new JButton(new ImageIcon("Pencil.GIF"));What could I do to make the background transparent and/or what software could I use instead of M$Paint ?
P.S. : sorry if my question seems silly, but I'm a newbie in Java coding...

Transparent images are GIF (256 colours) and PNG (true-colour, half transparency).
You can store the image with your code, *.class files. You then even can deliver all inside a clickable, executable .jar file.
This kind of usage is called "resource," and hence use getResource like this:
    java.net.URL imgURL = getClass().getResource("pencil.gif");
    ImageIcon icon = null;
    if (imgURL != null) {
        icon = new ImageIcon(imgURL, description);
    }You can use paths.
There exist versions of MSPaint that easily loose their transparent colour on saving.
For GIFs try internet palettes, or try to save as PNG (recent version).
Start with a transparent image from elsewhere.

Discover Bluetooth LE Device and its custom service with uuid and its characteristics

Hello Team,
I have a requirement for developing a library in C# which can be used in any windows app (Metro or Non Metro) apps to discover Bluetooth LE devices which are advertising a custom service with uuid and pair and find all the characteristics of the service
and send parameters and receive response.
I have tried 32feet.NET library which everyone talks about but realized it doesn't support Bluetooth LE devices. Is there any way I can do that? Or do I have write C# wrapper to use winsock2.2 library to call native code to access Bluetooth stack?
Please suggest. We have been able to achieve this requirement in Mac OSX by using their core Bluetooth framework.

Hello Priyanku,
>>Is there any way I can do that?
As far as I know, there is not such API that you can use to enumerate all services belonging to a Bluetooth LE device, nor all characteristics belonging to a service.
>>Or do I have write C# wrapper to use winsock2.2 library to call native code to access Bluetooth stack?
I suggest that you could try it.
Regards.

Customer Statement with opening and closing balances

Dear Forum,
The users want to generate the Customer Statement with opening and closing balances like the traditional one. The statement now generated gives the list of all open items as on date, but the users want the statement with opening balances as on the date of the begining of the range specified and the closing balance at the end of the period for which the statement is generated. Is there a way to generate the same from the system.
Thanks for the help.

Enhancing Customer Reports with Commands and Parameters

Hi All,
I am implementing the mentioned tutorial. I have succesfully deployed the AccessStatisticApplication PAR on portal. While scheduling the report from Content Management -> Reports -> Running Reports, it is giving error "Can't find bundle for base name com.sap.netweaver.km.stats.reports.DocumentAccessReport, locale en_US". Has anyone faced the problem, can anyone please help to remove this runtime error.

True, the application property service is apparently not to be used for a real-life scenario
You can definitely use the application property service in production scenarios - it's used by other components in a standard KM install, i.e. out-of-the-box.
in our case it forced the server down with deadlocks. 
This should definitely not happen! Did you get SAP support to take a look at this? Was it the most popular documents report that caused this, or some other custom code? There should be no such problem with this service, since it's been around for quite some time and in production use.

Even if the code sample is not to be used for real-life scenarios it could at least make use of something else than the application property service which isnt't optimal for this use.

The application property service is good for a lot of scenarios, so it is realistic to use in in real-life scenarios. The only time I have seen this approach (storing the number of hits on documents in the database) fail is in very high-load scenarios.
Could you provide me with a link to the documentation for the logging framework?

Difference between WITH CLAUSE and INLINNE VIEW.

Hi experts.
Can anyone explain me the diff. between WITH CLAUSE and INLINNE VIEW with some example.
Thanks in advance.

The WITH clause gives you a little more control on how the sub-queries are to be set up and used and allows the same subquery to be used multiple times without re-reading the data. Both simulate the functionality of views.
I feel the WITH clause provides better strucure and maintainablility.
The WITH clause aslo offesr two hints, INLINE and MATERIALIZE that can affect performance - both are used with the query in the IN clause. INLINE causes the subquery to be used as a subquery (inline view) while MATERIALIZE requests that the data be copied to a temporary table first. These hints are undocumented but are recognized by the user community.

I am making an album with Snapfish and would like to download ome of my photos from iphoto to snapfish, is this possible?

I am making an album with Snapfish and would like to download some of my photos from iphoto to Snapfish, is this possible?

You mean "upload"?
There are many, many ways to access your files in iPhoto: You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.
(Note the above illustration is not a Finder Window. It's the dialogue you get when you go File -> Open)
You can access the Library from the New Message Window in Mail:
There's a similar option in Outlook and many, many other apps. If you use Apple's Mail, Entourage, AOL or Eudora you can email from within iPhoto.
If you use a Cocoa-based Browser such as Safari, you can drag the pics from the iPhoto Window to the Attach window in the browser.
If you want to access the files with iPhoto not running:
For users of 10.6 and later: You can download a free Services component from MacOSXAutomation which will give you access to the iPhoto Library from your Services Menu.
Using the Services Preference Pane you can even create a keyboard shortcut for it.
For Users of 10.4 and 10.5 Create a Media Browser using Automator (takes about 10 seconds) or use this free utility Karelia iMedia Browser
Other options include:
Drag and Drop: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
File -> Export: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
Show File: a. On iPhoto 09 and earlier: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected. 3.b.
b: On iPhoto 11 and later: Select one of the affected photos in the iPhoto Window and go File -> Reveal in Finder -> Original. A Finder window will pop open with the file already selected.

Making a PDF with "Outline" and Bookmarks Using Pages

Hi, I'm using Pages 1 and I have tried making a PDF with outline breaks but I failed. I thought using paragraph styles for my document would work but when I exported my document to PDF, all I got was a PDF that only has the thumbnails view but not the outline view. Also, when I exported my document that has bookmarks to PDF, all the bookmarks don't work anymore. How can I make a PDF document using Pages with all the bookmarks and the organization just like other PDFs that I encounter? Thanks

Hello LadyinStilettos,
welcome to the Pages Discussions. If I remember correct, in Pages 1.x there is no way to export text links to PDF. An outline view creation doesn't exist.
If you want to have links in PDF (of the TOC, too), then you should upgrade to iWork'06. But outline view doesn't exist here like it doesn't in version 1.x.

Thumbnail Icons in list and Column View

I am trying to find out how to change icons for media files (pics/movies) from generic file type icons to thumbnail previews of the file. I Know its possibel because one of my folders (photos/iphoto/origionals.....)shows up in the column and list view as thumbnails. NONE of my other folders do though. I have tried messing with the view options, and i know you can view thumbnails in the ICON view in finder but this is not what i want to do. I also know that in column view you can preview files in an extra column, also not what i want. So anyone know how to make all icons in all finder views into thumbnails?
Thanks

The "icons" you are seeing are QuickLook icons that show a preview of the content in the file. AFAIK, there is no way to disable it. However, you can go into Finder>Preferences>Advanced and enabled the Show all file extensions option to help distinguish between filetypes.

Custom Icons with FAT32 USB Drive

Hi
I want to put a custom icon on a USB drive that's formatted to FAT32.
When I do this with a Mac OS Extended formatted USB drive, it works fine - the icon is attached to the dive, and appears when the the drive is mounted on another Mac.
But when I do this with a FAT32 formatted USB drive, the icon works on my desktop, but does not appear when the drive is mounted on another Mac.
Does anyone have a solution to this problem?
Thanks for your help.
Bruno.

Hmm, error -20 is:
-20 writErr Driver can't respond to Write call
I'm not sure why it would be doing that. I've got two PNY brand flash drives and have no problem erasing them under Tiger or Panther. You mention trying to repartition the drive. I suppose it's possible that you can't have more than one partition on a flash drive. Maybe the whole thing has to be one format type. Don't know that for sure, though. I've never tried it.

Section header with portrait and landscape view

My iBook project is being created so that it is available in both portrait and landscape view. This has been a tricky process since alot of content was distored when I created the layout using landscape and then attempted to adjust the portrait view after that. Currently, after many adjustments, I am attempting to remove the small "section number header" throughout the book at the very top of each chapter header in portrait mode. I was able to remove the the section number from the landscape mode, but can't seem to figure out how to do so with portrait mode (or if it is even possible?)
Help and suggestions are greatly appreciated.

Remember....layout in landscape - edit content in portrait.
Did you try to select the section number header in the style drawer and remove it from the master layout?

Metadata created with OEM and OLAP2 views

Why metadata created with OEM (v 9.2.0.1.0) aren't visible in OLAP2 views?
Cubes are visible only in OLAP_CUBES, and OLAP1_CUBES views only.
"Oracle9i Users Guide" says, that OLAP2 views shows metada created either with CWM2 and OEM, but i don't see the ones created with OEM.
And second question - has that issue something to do with the problem that i don't see cubes with "cube viewer" (and any other OLAP API application like OracleBI Spreadsheet Add-In)? I got error message BIB-10701.
I use Oracle 9.2.0.6.0 with OLAP option.

I know it is an old thread, but I thought I post the solution anyway ;-)

Building JSF 1.2 Custom Components with EL and standard components

Hi all,
I have built custom components in jsf 1.1 with great success but i am finding replicating the same functionality in jsf 1.2 very difficult. I have some conditions for my new custom component.
- Using jsf 1.2
- Must use unified EL, i am using a UIComponentELTag
- iam using jsf standard html components from javax.faces.component.html here in particular i wont HtmlCommandLink.
Essentially i am constructing a real time command menu. I have a backing bean from which i get command names and descriptions values. I wont to then in real time construct a table of links (using HtmlCommandLink) - all this work is to be processed by a custom component. Basically the commandLink issues a command in my backing bean, a parameter (param) is passed with the commandLink, this is later picked up in the backing bean method.
I can generate the table, and all the HtmlCommandLinks, i have simply looped throught and encoded each of them.
What i can do: i can see the table and the HtmlCommandLinks, but the links dont perform any action when i press them.
What i want help with:
I want to encode a HtmlCommandLink in my custom component with a param, traditionally i would set the action but this is now deprecated, and i need to use the setActionExpression method. I have tried to do this but the actions are note fired its simply doesnt function.
Note:
In jsf 1.1 I use to loop through all the HtmlCommandLink and peform their processDecodes method within my custom components very own processDecodes. The same in jsf 1.2 doesnt seem to yield any results.
Can someone give be an example or solution to this? I have read articles on the net and they seem to all discuss jsf 1.1 which i have done and it works, but i am using unifed EL and jsf 1.2 now.
Many Thanks,
Kev

Oracle equals_path condition NOT working with table and materialized view

The user i am using is xdb with dba role.
1.When i try to use the statement
SELECT PATH FROM xdb.path_VIEW
WHERE
EQUALS_PATH(res, '/home/OE/PurchaseOrders/2002')=1
the result is
/home/OE/PurchaseOrders/2002
2. When i drop the path_view and recreated it like materialized view with statement
create MATERIALIZED view path_view as
select /*+ ORDERED */ t2.path path, t.res res,
xmltype.createxml(xdb.xdb_link_type(NULL, r2.xmldata.dispname, t.name,
h.name, h.flags, h.parent_oid, h.child_oid),
'http://xmlns.oracle.com/xdb/XDBStandard.xsd', 'LINK') link,
t.resid
from ( select xdb.all_path(9999) paths, value(p) res, p.sys_nc_oid$ resid,
p.xmldata.dispname name
from xdb.xdb$resource p
where xdb.under_path(value(p), '/', 9999)=1 ) t,
TABLE( cast (t.paths as xdb.path_array) ) t2,
xdb.xdb$h_link h, xdb.xdb$resource r2
where t2.parent_oid = h.parent_oid and t2.childname = h.name and
t2.parent_oid = r2.sys_nc_oid$
then the equals_path condition STOP working !!!
3. The same experiment, but i recreate it like table
create table path_view as .... using the rest of the statement ...
Can someone help me to understand why equals_path is NOT working on table and materialized view !

Thanks Jonah. I was under the impression that I already had it but seems like it has to be a direct priv - thru a role doesn't work.
I granted the reqd privs and then it worked fine. Thx for your help!
