How to Conditionally Rende the Images in af:treeTable...

Hi,
I need to conditionally render the Images in af:treeTable.
First let me explain my requirement clearly...
I need to display Dept --> Emp in a tree View format... Some thing like
Dallas
--> Smith
--> Scott
--> Tiger
New York
--> XXXX
--> YYYY
--> ZZZZz
Along with these i need to display Add and Delete Command links in second column.
But Delete Operation should not available for Departments...
So how to conditionally stop delete image from rendering for departments...
Waiting for your response...
Thanks in Advance...

You don't need disabled though rendered property. Sorry.
You'll find it in property inspector for image component. There you will enter the binding to the method that you should write in backing bean (method name must start with "get"). You can also use binding editor for entering correct binding string while working in property inspector.
Method in backing bean, for example:
public Boolean getRenderedImage(){
Object obj = FacesContext.getCurrentInstance().getApplication().
createValueBinding("#{row.row.currentRow.dataProvider}").
getValue(FacesContext.getCurrentInstance());
/* next ushould cast this object to whatever it is and se if it should be rendered or not and return true or false. To see what is the cast object you could put break point after getting obj and see Class name.
One thing. You should see what is the binding name for row elements in your table. By default it is "row" if you did drag&drop. If it is "row1" you should change the string above to: "#{row1.row.currentRow.dataProvider}".

How can I read the image from database into form

hi everyone
if I have table like this
create table test
(id number(10),
pic long raw);
in this table record
in form If I have block non database
how can i read the image into non database item
I try with this code but no good
select pic into :photo from test where id=5;
photo its non database item kind image
how can i invoke image into item
thanks alooooooot

Hello,
You can't select image with select query. You need to create another database block from test table which has item binds with database pic column. Now in where condition in test block's property you have to write id=5. Change test block's properties UPDATE ALLOWED, INSERT ALLOWED, DELETE ALLOWED to NO. Only Query allowed property set to YES.
Now in your particular trigger write the code
GO_BLOCK('test');
Execute_Query;
please mark if it help you or correct

How do I set the image size in PS touch to print to my Epson printer w ithout losing any of the picture. PS Touch appears to be showing pixels and not inches, how can I covert it toshow inches?

I am using PS Touch from my tablet . I am importinga photo from an SD card . When all editing is completed I then send it wireless from the tablet via Epson I print to the printer. It all works great except that part of the photo at each end is cut off and does not print. I am printing on 8.5 x11 paper.
How do I convert the image size in PSTouch frm pixels to inches?

Epson's iPrint has always been an oddball. It will always "zoom in" on an image to print even if you have the proper dimensions and resolution set for actual print size. I think other users have reported this, at least on Android.
You can't have PS Touch show inches instead of pixels at this time but you can use an online website to find out what you need to fit within a particular resolution. (Google "pixels to inches calculator".)

Most Simple Back Up:
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex: Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically.
Example of such apps: Chronosync - but there are many others. Search on MacUpdate or the App Store
If you want to back up the Photos only:
Export them using the File -> Export command.
This User Tip
https://discussions.apple.com/docs/DOC-4921
has details of the options in the Export dialogue.

How can we get the image which is stored in clipboard by labview, is there any functions available like text from clip board

How can we get the image which is stored in clipboard by labview, i can get the text in clipboard by using invoke node directly.but i cannot get the image, is there any functions or vi available.(image is in Png format)

The Read from Clipboard method is, unfortunately, limited to text. If the clipboard contains an image then you need to use OS-specific functions calls. This is an example program for Windows. It's old, but it should still work.

How do you shuffle the image order when creating a new slideshow in apterture 3? i would like to do this automatically when creating a new slideshow. i see how you do it when you just play a slideshow.

how do you shuffle the image order when creating a new slideshow in apterture 3? i would like to do this automatically when creating a new slideshow. i see how you do it with presets when you just play a slideshow, but i don't see an option to randomly shuffle the slide order when you create a new slideshow. i know you can sort it by different fields, but i want it to be random. thanks.

If you want to rearrange images in random order you can try an AppleScript:
retrieve a list of selected images from Aperture
shuffe the list properly
create an album in Aperture and add the images from the list to the album (make sure that the album set to be orederd manually)
Here is a sample script that shuffles the selected images and displays them in random order in Full Screen Mode:
on removeItem(ims, i)
-- remove the item at position "i" from a list ims
          if ims is {} then return {}
          if (length of ims is 1) then return {}
          if i < 2 then return rest of ims
          if (i = length of ims) then return (items 1 thru (i - 1) of ims)
          if i > (length of ims) then return ims -- should be error?
          return (items 1 thru (i - 1) of ims) & (items (i + 1) thru (length of ims) of ims)
end removeItem
on shuffle_items(ims)
-- shuffle the items of the list "ims" randomly
          local numitems, ims_shuffled, nextrest, nextpick, i
          set numitems to length of ims
          if length of ims < 2 then return ims
          set ims_shuffled to {}
          set nextrest to ims
          repeat until nextrest is {}
                    set i to (random number (numitems - 1)) + 1
                    set nextpick to item i of nextrest
                    set beginning of ims_shuffled to nextpick
                    set numitems to numitems - 1
                    set nextrest to removeItem(nextrest, i)
          end repeat
          return ims_shuffled
end shuffle_items
on shuffleIms()
-- retrieve the selected images from Aperture
-- and display them in random order in full screen mode
          local imageSel, shuffled, i
          tell application "Aperture"
activate
                    set imageSel to (get selection)
                    set shuffled to my shuffle_items(imageSel)
                    set fullscreen to true
                    if imageSel is {} then error "Please select some images."
                    repeat with i from 1 to count of shuffled
                              reveal {item i of shuffled}
delay 3 -- chnage that to the time you want
                    end repeat
                    set fullscreen to false
                    return shuffled
          end tell
end shuffleIms
shuffleIms()
Some more code snippets to go from here:
To create an album:
                    tell library 1
                              if not (exists album "shuffledAlbum") then
make new album with properties {name:"shuffledAlbum", image version:shuffled}
                              end if
                    end tell
And to add the images from the shuffled list to the album:
                    repeat with i from 1 to count of shuffled
                              duplicate item i of shuffled to album "shuffledAlbum"
                    end repeat

How do I find the image name and media_link for an ubuntu image in the Gallery?

I am trying to create VM using Python API.
I have a custom Linux image:
image_name = 'cloudN-Azure-20150205-os-2015-02-05'
media_link = 'https://portalvhds10ssz63zgvb9g.blob.core.windows.net/vhds/cloudN-Azure-20150205-os-2015-02-05.vhd'
When I used this image to create VM, it failed.

How do I specify the image_name and media_link in my Python code? Basically, where and how do I find the image name and media_link for an image in the Azure image Gallery?
Thanks in advance...

hi sir,
Did you try to use "List OS Image"? we can get the property form the results:
result = sms.list_os_images()
for image in result:
print('Name: ' + image.name)
print('Label: ' + image.label)
print('OS: ' + image.os)
print('Category: ' + image.category)
print('Description: ' + image.description)
print('Location: ' + image.location)
print('Affinity group: ' + image.affinity_group)
print('Media link: ' + image.media_link)
print('')
Please try it. Any questions or it doesn't work, please let me know.
Regards,
Will

You may the sort set to Custom. Click the dropdown menu on the toolbar (to the right of the word sort) and change to capture time.

How do I change the image selected for the finalized movies pane in all events?

How do I change the image selected for the finalized movies pane in all events? I made a movie some time ago in iMovie, and a still from this now appears as the image for Finalized Movies in the All Events pane (as well as showing up if I then click on this pane to take me to Finalized Movies). Anyone know how to change or delete this image, please?

Unfortunately, the suggested solution in that thread does not work and the thread appears to be closed to replies. That is, even though I am logged in the Reply|Quote|Mark as answer|Report as abuse items are missing.
The suggested solution is:
First, I found I had "img100.png" in C:\Windows\Web\Screen and
C:\Windows\WinSxS\x86_microsoft-windows-themeui-client_31bf3856ad364e35_6.2.9200.16384_none_69ee3fa2269e545e
1. Belonging to the Administrators Group, I replaced file Owner TrustedInstaller with my Username on both "img100.png" files
2. After resizing the image I wanted to see on the Login screen to the resolution of "img100.png" file,
I copied and pasted it to both "img100.png" files keeping this way the format (extension) and resolution of the original "img100.png" file,
which I permanently deleted.
However, I have not been able to replace the img100.pgn in C:\Windows\Web\Screen even after taking ownership of it and setting the permissions for my userid to All. I edit it with mspaint and then try to save it. The save starts that then says the
save was interrupted.
The appears to be some additional protection besides the standard acls.

The same way you put them on the phone. Connect the phone to iTunes on your computer, click on the name of the iPhone, then the Photo tab. Uncheck the albums you don't want on the phone and click Sync.
