How can I use the defaults command to edit a sub key in an array of plist?

For example, how could I edit the Name key in the array?
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Test</key>
<array>
<dict>
<key>IPAddress</key>
<string>xxxx</string>
<key>Name</key>
<string>yyyy</string>
</dict>
</array>
</dict>
</plist>

I realize you are asking specifically about 'defaults', but as they concede in 'man defaults', it may not be the best tool for editing properties in "complex" structures, such as those buried in dicts within arrays, etc.
As an alternative, it looks like in 10.5, '/usr/libexec/PlistBuddy' is now a part of the standard install - 'PlistBuddy' may be more useful for this sort of task.
For example:<pre>
/usr/libexec/PlistBuddy -c "set Test:0:Name zzzz" /path/to/file.plist</pre>

The icon editor at least up to version 7.0 of LabVIEW is not written as
VI but directly implemented inside LabVIEW, which is written in C/C++.

How can I use the find button in Edit ADF Table in JDeveloper 10.1.3

Hi all,
in JDeveloper 10.1.3
How can I make the find button work in
the same Edit ADF Table without adding new view ?
thanks

Hi there,
it depends on what you mean by adding a new view object. You[b] don't have to create a new viewobject. You do have to add a second instance of your existing view object to your page.
Form scratch works more or less like this. Drop your view object as ADF table on the form. Add the find and execute operations. Drop the same view object on your form but now as ADF search form. Place the fields form the search form in the corresponding columns next to the existing fields. For each #{row} field ,and the find button, set the rendered property
#{bindings.testUserIterator.findMode ==false}. For each inputfield, and the execute, set the rendered property #{bindings.testUserIterator.findMode ==true}.
Now it will work.
I hope this is what you are looking for.
Good luck

How can i change the default application that Lion uses to open a document?

how can i change the default application that Lion uses to open a document?

Right-click on the document, select Get Info... In the lower half of the tall window that opens is a section labeled Open With (you may need to click on the disclosure triangle to see detail). Select from the pop-up list which app should open this document. If you want that to become the default condition, click on the Change All... button.

How can I change the default application for a content type?

Running a version of Linux, the default application for PDF files is "Use Document Viewer (default)", which appears to be /usr/bin/evince. I'd much prefer to use /usr/bin/okular; how can I change the default. This question is NOT about how to change the function that is automatically applied when I access a link, in this case "Preview in Firefox", but rather to the default application that I can select when I download a file being viewed in Firefox's previewer.

This is real progress, a solution to the problem as posted. The command:
xdg-mime default okularApplication_pdf.desktop application/pdf
makes okular the default.
However when I added okular to the choices for applications in:
* Edit>Preferences>Applications>PDF
the popup box that appears when I click Download on the preview page changed. The pulldown menu that appears next to "Open with" used to have 3 entries:
# Document Viewer (default)
# Acroread
# Other
Now it has only 2:
# Okular (Default)
# Other
I'd like it to read
# Okular (Default)
# Acroread
# Other
How can I control the entries in this pulldown list?
Also, how can I make the default choice in the popup box be
* Open With <whatever> , rather than
* Save File ?

How can I change the default URL in hyperlink inspector

How can I change the default URL for link to external page in the Hyperlink Inspector?

You can't change the default url in the inspector.. but an easier way to do it rather than editing the box everytime you need to build a link is to copy the url you want to link to and then highlight the text or image that users will click on and then click enable hyperlink.. when you do that whatever the last url you copied using "command" "C" will automatically be entered into that box and replace "livepage.apple.com"
It saves alot of time if you are doing alot of links.
Hope This Helps!

For sideloaded content the nook pulls the metadata from ePub file itself. I would suggest looking at a program like Sigil or Calibre that will let you edit the metadata in the book to make it appear like you want.
For the PDF vs ePub - No, that's the way PDFs work (think of them as graphics, not text), wheres ePubs are Web Pages - so no you can't them to behave exactly alike without converting the files.

How can I change the default driver to OracleXADataSource in JDeveloper

Hello,
How can I change the default oracle driver: oracle.jdbc.OracleDriver to oracle.jdbc.xa.client.OracleXADataSource in JDeveloper Studio Edition Version 11.1.1.0.2, Build JDEVADF_MAIN.BOXER_GENERIC_090328.0229.5205.
If I modify the file connections.xml from jdeveloper\system\system11.1.1.0.31.52.05\o.jdevimpl.rescat2\connections in the sense that I change the driver class, then in JDeveloper when I test my connection I have this problem: Test failed: oracle.jdbc.xa.client.OracleXADataSource cannot be cast to java.sql.Driver
Why do I need this XA version of the oracle driver? Well I tried, from a book to reproduce the model of an application: entities, stateless and stateful session beans, mdb, web services and a client to test one part of the model.
And because of the JMS server I need an XA driver.
I deployed to the integrated wls 10.3 and when I test my client, if I use the default driver for the connection the an error message appears tell me either to emulate two-phase commit or to use XA driver.
My application works very well, if I configured in the console of the integrated wls 10.3 a datasource with the same name as my ide/application connection that has for the Driver Class Name: oracle.jdbc.xa.client.OracleXADataSource in the Connection Pool tab.
Thank you.

Open DIsk Utility and in the toolbar select Disk Image. The file selector will open and you'll have to do three things: 1) just as with any file, name it and point the file selector to where you want it to be saved, 2) near the bottom you'll see name - type iWork 2013 and 3) below that select the image size. Click on size, choose custom and type 1500 MB then click on the Create button.
Some time will pass and then you'll see an external disk pop up on your desktop and/or the Finder window sidebar. Drag the three programs into it and eject it like any other external disk. Now delete the programs from your applications window.
Where ever it was you pointed the file selector to you'll see the file you created. Double click on it and the disk image will mount again.

When I opt to "download this as a file" from my email account, Firefox defaults to notepad to open the file. How can I change the default to MS Word?

Question
When I opt to "download this as a file" from my email account, Firefox defaults to notepad to open the file. How can I change the default to MS Word?

Is FF downloading the file as a .txt file? If so, go to "Folder Options" in the windows control panel. Click on the "File Types" tab. Scroll down until you reach the TXT file extension. Look to see what that extension opens with (lower part of panel). It probably shows notepad. Click on the <Change> button. Scroll down until you find "Microsoft Word." Select it and click the <OK> button. That should show the TXT extension is now associated with Microsoft Word. Click the <Close> button at the bottom of the panel.
If FF is downloading the file as any other type, use the same process as above except look for the corresponding extension instead. If the extension is not listed click on the <New> button and create an association using the extension in the file name and then associate it with MS Word.

How can I use the built-in Isight camera with an external camera (usb/firewire) at the same time?

How can I use the built-in Isight camera and an external video camera at the same time?
I'm wanting to stream over Oovoo/Skype/etc. using 2 cameras.
Thanks

Simple question with a not so simple answer.
(a) If you mean that you want to run multiple apps simultaneously using a different camera with each app, you may encounter computing power limitations. Digital video is processor intensive. The only way to know if your Mac can do this it to try it. If the video does not work together but each app works when it it the only app running, you are likely overloading your Mac's ability to process and/or move all the required data in your data bus. You can get a better indication of whether this is the case by watching your Activity Monitor utility while running the apps you want to use.
(b) If you mean that you want to have more than one compatible camera connected to your Mac simultaneously for ease of changing between video sources, some, but not necessarily all, apps you are using to operate your camera(s) allow you to select between your cameras.
How you select among connected cameras depends on which application you are using. Here is how camera selection works in a few examples:
(1) For iChat, you can choose which iSight you use in the "Camera:" choices bar in iChat > Preferences... > Audio/Video that appears when more than one compatible camera is connected. Although your camera choices will be different, the choices bar will look something similar to the Preferences settings shown here:
If you cannot see the "Camera" choices bar, your Mac is recognizing only one (or none) of your cameras. In that case, consider the suggestions fromhttp://support.apple.com/kb/HT2090 for iSight problems or refer to your other camera's documentation for help.
This particular choices bar solution applies ONLY to iChat. Most other applications also have settings that allow you to choose which camera to use. However, they do not all work the same way.
(2) For instance, iMovie HD's camera choice is NOT set via Preferences. When you have more than one compatible camera connected, iMovie6 HD uses a drop-down menu choice something like this (depending on which version of iMovie you use):
Note: Because I had no built-in iSight connected when I made this example, and because my external iSight was not connected, the drop-down menu showed only "Time Lapse." Because your Mac has a built-in iSight, your built-in iSight would show in the drop-down menu even when no other camera is connected. Connecting an additional Mac compatible webcam should allow you to choose either camera.
Other iMovie versions work slightly differently.
iMovie 9 (from iLife '11) uses a different camera choice button shown in this article:
http://docs.info.apple.com/article.html?path=iMovie/9.0/en/mov39f84285.html
iMovie 8 (from iLife '09) is slightly different as explained in this article:
http://docs.info.apple.com/article.html?path=iMovie/8.0/en/10172.html
In general, you can use your Mac's help for the application in use to find out how to select among more than one connected camera.
(3) Photo Booth in Snow Leopard 10.6.x and later uses the Photo Booth > Camera menu command to select which camera to use.
Note for readers with older Mac OS X: The previous version of Photo Booth that came with Tiger (10.4.x) is such a simple, basic app that it offers no menu selectable choice. Unless your built-in iSight is already occupied as the camera being used by some open application before you launch Photo Booth, Photo Booth will use ONLY your built-in iSight.
However, you can use the trick from ¶ 4 of http://docs.info.apple.com/article.html?artnum=302781 to let Photo Booth use an external camera.
(If you have an external Firewire camera connected, it may be used in preference to any USB webcam. If that is a problem for you, merely disconnect the problem Firewire device.)
(4) For FaceTime, launch the app and click the Video menu item.
If your Mac recognizes more than one connected compatible camera, a "Camera" section listing the cameras from which you can choose will appear there. Clicking on the desired camera name will let you select the one you want as shown in this image from my Mac Pro and LED Cinema Display:
If your Mac recognizes only one compatible camera, the "Camera" section will not appear in the Video menu, but FaceTime will automatically use the connected camera that is recognized by OS X.
(5) I do not use Skype oir Oovoo. For those or other apps, see Help for each app for info on how to select your desired camera.

How can I specify the default tab in a CHM Output?

My company uses CHM-based help for some of its products. We build the CHM files from RoboHelp 9, and while these CHM files don't really have a full Index attached to them, the Index tab shows up in the output anyway. Unfortunately, we are suddenly seeing that when the CHM file is launched from our program, the Index tab is displayed by default. We'd rather have the Contents tab be the default look, especially considering that the Index does not exist.
I have poked around into how you can specify a default tab for a CHM file, and the only information I have found suggests that using a CHM file creates a file (HH.dat) that specifies which tab should be displayed on a user-by-user basis, and that the last tab displayed when you close the CHM should be the first one displayed when you re-open it. While this is true if you open the CHM independent from the product, when you launch it from our program, it's all Index, all the time.
So, my question is: How can I specify the default tab for a CHM file? Or, failing that, how can I excise the Index tab from my CHM output.

Hi there
This will be something up to your application developer to resolve. When s/he issues the call to open the CHM, there are parameters that may be used to always open with the desired tab "in front".
Point your developer to the link below and advise that s/he is most likely interested in the section titled: Programming Tips.

How can I get the default value of a particular preference in FireFox?.
I know I can see the default value for some of the preferences in about:config but, I need a programatic way to get the default value.
I see some that there are values for preferences in firefox.cs but I am not certain that these are being used as the default values for preferences. prefs.js in user's profile only has the updated values and not the default values.
Any help towards acheiving this programtically is greatly appreciated.
If the default values are stored in a file, kindly let me know the format in which it is stored for me to parse it programatically.

Dear Friend,
Here when you have the callableSattement as ?=proc(?), the first ? is an output parameter. So you should register it as out parameter using registeroutparameter.
Then you can get the value from the outparameter using callablestatement.getXXX().
Try that way.

How can I change the default pdf reader from the installed (but not yet registered) Adobe Acrobat 9 Pro to Adobe Reader XI?

How can I change the default pdf reader from the installed (but not yet registered) Adobe Acrobat 9 Pro to Adobe Reader XI? I'm having some hiccups getting Adobe to register the software, but since I set it as the default .pdf reader during setup, things try (and fail) to open in the as yet unregistered software. How can I change it temporariiy to the Acrobat Reader XI that I have installed?

Anubha,
It worked! Thank you so much.
I'd opened file with the 'Open with' feature then clicking Adobe Reader,
but that didn't do it. When I used 'Open with', then 'Choose default
program...', it worked like a charm.
Again, thank you!
