The Source of an Image to link to the Icon of a Collection of table property
Is it possible to do what I can't seem to make it work? For example, the image is called myImage and I need my collections of table icon to change in change source myImage. I tried this but it does not work: -.
{id:}
"First element" , label: "First element" , icon: "{myImage.source}" },
Can someone help me on this? Thanks for your suggestions.
Try this out. Julst is a start. This will save your image to disk. Yes, you can replace the existing images.
You want to save the images on the spot I guess?

capture the image
var imageBitmapData:BitmapData = ImageSnapshot.captureBitmapData (myhtml);
create a bitmap
var s:Object = new Bitmap (imageBitmapData);
Encode to JPEG
var jpgEncoder:JPEGEncoder = new JPEGEncoder (60);
var ba: ByteArray = jpgEncoder.encode (imageBitmapData);
var filename:String = "MyImage"
resolve the path to a file object
var file:File = File.applicationDirectory.resolvePath (filename);
var wr:File = new queue (file.nativePath);
create a filestream
var stream: FileStream = new FileStream();
open/create file, set the filemode to write in order to save.
Stream.Open (wr, FileMode.WRITE);
write your byteArray in the file.
stream.writeBytes (ba, 0, ba.length);
Close the file.

Allowing the movement line temporarily on partitioned table
Hello
Using oracle 11.2.0.3 and have tables that are hash of composite range partitioned.
We need to update the dates of theses for a small percentage of records 1 < %.
Normally we have movement line enabled so that can copy the lines in the temporary table, update insert_table, remove lines concerned living table and replace them with the new dates of the partition.
Another option allowing possibly temporariliy movement line.
Thoughts?
Thank you
Is there any disadvanatges to allowing it for example from performance perspective.
Haerd was a bad iade of have it activated - perhaps isn't so bad.
Tom Kyte meets ALL these questions (and more) in this blog:
https://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:35203106066718
If never actually cause you a row to move, then there is zero overhead. All the movmement of line enable does is give us permission to move a line, if you do not ask us to move the line - extra "nothing happens.
. . .Follow-up Friday, March 10, 2009-02:00 UTC:
Is there something wrong? Only you can answer that you have any application that expects the rowid is constant for a line? If yes - then it is false, if not - then it's probably OK.
Any overload? No, it's just allowed to change a rowid if you perform an operation that would have caused a rowid to change - alter table t shrink compact space, flashback table t to..., update t set partition_key = some_value_that_moves_row;
You can change a table instantly to activate circulation line - whatever the size of the table - it'll be instant - you have no need to do advance if you don't want, fairly easy to add later...
I recommend you to read the ENTIRE blog because there are many other issues that should relieve your concerns and good examples.
As says this quote above if you have an application that expects the ROWID is constant for a line, then you might have a problem.
ROWID is the way the FASTER to search for a line. Sometimes the ETL process are complex and multiple operations on a line by multiple, separate steps.
You can often get huge performance gains in saving the values ROWID lines collections or tables of work/temp during ETL processing. For example, a query in PL/SQL can use ' RETURN ROWID IN... "to get all of the ROWID that affects the query.
This set of ROWID can be used in the following queries to locate the exact lines directly without the need of ALL indexes or other search criteria: WHERE ROWID IN...
If the ROWID has changed during the process, it would be disastrous if these processes are written in:
1. Enter the current setting of moving the line
2. turn off the movement of the line during the process
3 re-enable line movement ONLY if it has been activated prior to the start of the process

Hello, I am very interested in buying Lightroom 5.2. I tried the RC that was missing today. Yet, I have several questions that I can't find really good conclusive answers, I'd like to get an answer before buying LR. Please do not write maybe like this or that (assumptions), because I don't want to start my entire workflow and then realize that I have to change all around, please reply, if you know for sure that something works and you are, preferably, using this method too.
Can I create a snapshot and replace it with an image (or link another picture than the current photo)? Details: I made adjustments in iPhoto until now I want my (unpublished) masters, some RAWs JPEGs, create a snapshot and set the photo as the one to keep. If it is not possible, all of the recommendations (in addition the usual masters of backup and import changes).
What I do is I have to assign some metadata down battery photo indicating of don't not to export the picture. Then, I use either a collection of smart to find the photo I want to and can not find the photos, I don't want and export all in the smart collection. or I use a Collection of post Smart, even once allows me to select only the pictures I want and not those I want.
Of course you manually uncheck items you want to export, which work as well.

InDesign CS4 does not display the icon in the shape of triangle for the images changed into links
My InDesign crashed the other day and now it gives me is no longer the yellow triangle icon in the links Panel to indicate that image has been changed and must be updated. I generally do not connect the image to the original through Indesign, but work independently in Photoshop. This has never been a problem. After that I updated the image in PS, the triangle appears instantly in ID in order to be able to click on it and update the image.
I can always click on the Refresh button to update the image, but I wish that these rear indicators because it helps me with older documents - so that I can know what are the images really need to update and which are not.
I restarted the Panel and launched and closed the bridge such as suggested in other older discussions, and he has not made a difference. I also noticed that if I try to open the original image by ID with open with, the icon for the PS, for example, doesn't think I'm in PS (it opens the image in Windowd Paint). It makes me wonder is the whole connection between ID and PS is messed up. How can I correct this connection?

To create a ToolTip text for the image with multiple image map links
Hello
RH6 using, that I imported a picture into a topic. For the images that I have created several maps image to post a link to other topics. However, I can't create a map image additional to that same image that includes only the screen Tip text. I get a message of invalid value: "Please select a file, bookmark or topic to bind the hyperlink to.»
Is there a way to create a popup only the text of an image with multiple image map links? My final output will be to WebHelp but possibly migrate FlashHelp in the near future.
Thank you
FMnRH
Thank you
FMnRHIf the image is at the beginning of the subject, or all alone in a reference topic, you can put "#" (without the quotes) as the link for each area reactive.
If the image is larger than the viewing window, it can jump to the top, but only if the user clicks on the link.
I tried wz_tooltips and like it. I agree with Leon, it will take time for the first image but maybe go faster later.

Design mode does not show images or link to CSS
I use Dreamweaver 5.5 year now but today I changed inadvertently a few settings and design mode is more image display or applying the CSS settings. Some of them are local and others on the Internet - it is not serious. The fundamental problem is that Design view is not tender hand of the source code for posting a link to other files. How to restore this feature?
All rights, it is necessary to close and re-open Dreamweaver before the display of the external files works. So now I'm back in business, but it would be nice if indicated.

Change the preview image of audio files (no icon) in the Finder?
I know that this is easily done in iTunes, simply by changing the 'work' of the song.
But I need to do it outside of iTunes, and I need to change the preview image and not the image of the icon.
Many tutorials show how to easily change the icon of a file, but I found nothing on the change in the preview...
As said, I need to do it in the Finder, or perhaps with Quicktime? I don't know how I can use it, if necessary.
I need to have the work I want already in the file before you import it into iTunes, regardless of the reason for which I won't get into that.
You can use a tag editor to third party such as Meta-z for the files to m4a format. I would recommend the Rage of free media now, but I can't find a download link works.

Interactive images that link to Images
Hi all
My experience so far is the Microsoft HTML Help, but I just started a new project where I think the best solution for what is necessary will WebHelp. I did a bit of a departure, but I encountered the following problem when you try to do something I've done MS HTML Help several times:
I have a jpg image of a light bulb that I add a hyperlink to in order to link to an another jpg image as a screenshot of what I refer to. In this way, the reader can choose if they wish to see the screenshot or not, and the screen is not dominated by the large images that I sometimes need to display. The way I do it is to create a hyperlink to a file and select the appropriate jpg image to link to. It works perfectly in MS HTML Help and WebHelp it seems to do nothing (the browser doesn't even say "Cannot display the Page"). The status bar of the browser displays "javascript:void (0)" or something similar.
There are additional restrictions on the types of files I can for a hyperlink in WebHelp? I had a glance using RH, and it suggests that the only files no matter what help file can link to pdf, doc or xls is, so I'm a bit confused.
Thanks in advance,
darkagn
PS I use 6 HR. See you soon!Hello darkagn-
I don't do that often - no problem. I insert the image link (I use the image of an 'I' instead of a light bulb) and then set the action drop-down DHTML text and insert the image target in the drop-down text box. Click to see the image, click again to hide - works fine.
Kind regards

How to get a glimpse of the images instead of the icons in the finder
Hi, since I downloaded El Capitan pictures cannot be previewed in finder more unless I open them in the application preview or in a sidebar. Instead, according to icon, on top of the image name, she never shows just the jpeg preview icon. I checked the option to see the preview instead of the icon is activated in the options of presentation/overview, that changes nothing. When it's like that, it is impossible to get an overview of images or do not lose time to open them individually.
Any ideas? Thank you very much.
To help read the information on one of the jpeg files (command - I),
According to open it with, check if the preview application is associated with jpeg files:
If not put open with: on the Preview.app, then click all change...
NB. You will need to restart the Finder subsequently.

I dragged a URL in the URL box - in this case a 2nd Yahoo! email login address so I could quickly switch between accounts - in the toolbar links (the one with the "Most visited" link.
Noting that the new URL link didn't have a Yahoo! icon I right click on the link and found that there is no option to change the URL link icon to, well, anything (!) as we can do for most of the files in Windows Explorer.
I could change the text label of the link without problem.
Is he buried somewhere else in Firefox the ability to do so and if so where?
If not can this option included in the dialog box properties of links in the future, please?
I would be really grateful one answer I know that my question has not fallen into the "bit bucket".
See you soon,.

- I'm trying to prepare my project, so I use a funny icon instead of the normal image for my icon, my folder icon, but when I cut & paste it in another location, or use the folder to another computer my my icon disappears and show my folder as another icon of folder that you see in all the computers.

You can't do anything. The icon is the local computer. If you move the folder to another PC, the icon will be missing.

small images in the icon on the desktop
Sometimes when I create a shortcut on my desktop shows a white square with upper right corner folded down, but the real image of the shortcut is very low. For example: my icon for g-mail is a small envelope framed in red and my bing is a small orange square with a white b in it, but neither one is a full icon. They are inside the white square.
The size of the area corresponding to the icon on the desktop is fine. A small image is sometimes found inside the white square. The icon is 1/2 inch to 1/2 in., but the real picture is nch 1/4 by 1/4 of an inch.
Is there a solution to this problem or am I stuck with an another inconvenience of Vista?
