How to show image from within a symbol

Howdy,
EA, Win7
I've imported an img on to my stage, converted it to a symbol (and unchecked autoplay).
Then I deleted the img from the stage, the symbol w/img still remains in the Assets > Symbols section.
What I want to do now is simply have the img (that's inside the symbol) appear when I click on a button/text.
Is this possible? I've tried...
sym.getSymbol("image").show(); where "image" is the name of the symbol
but this doesn't work. What am I missing?
Thanks for any help,
R

Thanks resdesign,
Looked over the Edge API and it's kinda vague on how to interact with symbols. There's nothing that specifically says 'A symbol must have an instance on the main timelline in order to interact with it'. The API seems to make the assumption that that people automatically know that. Yet when I see something like the following from the Edge JSAPI...
Access a symbol timeline from the main stage
To access the timeline of a symbol from the main stage, use the following in your event:
// Play the symbol timeline sym.getSymbol("symbolName").play();
...it makes me think that I can just call up the symbol on to the the main stage without having an instance of the symbol already on the stage/timeline.
Would be curious to know where in the API it mentions that in order to interact with symbols they must have an instance on the main timeline/stage.
Cheers,
R

How to show image from database file name?

Hello,
Reports version 10.1.2.3
OS: Windows server 2003
Client: Windows XP
Can someone please explain how to include an image in a .PDF report that is located on the file system and its location is read from the database? I've read the doc and it's not very clear.
Thanks,

Hello,
http://www.oracle.com/webapps/online-help/reports/10.1.2/topics/htmlhelp_rwbuild_hs/rwcontxt/props/pi_col_read_from_file.htm
Suppose that for each of your employees you have a .bmp file that contains a picture of the employee. In your employee table, you have a column named PICTURE that contains the name of the .bmp file with the employee's picture.
To generate a report that displays the employees' pictures, you select the PICTURE column in your query. In the Column properties for the PICTURE column, you set Read from File to Yes and specify Image as the File Format. Reports Builder will display the files pointed to by the PICTURE column wherever you have referenced the PICTURE column in your layout.

How do I set a variable on the main timeline from within a symbol?

Just getting started with Animate and coming to it from Flash, as may be apparent from my question. How do you set a variable to the main timeline from within a symbol?
I have 24 pairs of clickable elements, each in their own symbols, and all 24 of those symbols sit inside another symbol. I want all 24 to be able to set the same global variable when clicked. I can't find that this question is addressed anywhere, which makes me think I may be stuck in a Flash mindset and approaching the task in the wrong way. (There are however MANY discussions of how to address objects at different levels in the hierarchy. That's well covered.)
Relatedly, how do you access a function on the main timeline from within a symbol?
Adobe should consider putting together a support page (or pages) just for folks migrating form Flash. In the materials I've encountered so far there seems to be a studied effort to refrain from mentioning Flash in any way. I imagine there are a lot of people out there like me who have a deep background in Flash coding, but are just getting started with Animate. We don't need help with most of the basic concepts, but we may still have some pretty basic questions about how to accomplish some things in Animate because our Flash knowledge is getting in the way.

Hi Bill,
There are plenty of threads on here about scope, but here's one way to create a global variable:
// code on Stage.compositionReady
sym.myGlobalVar = 1;
Then, anywhere in your project, you can check/set that var like so:
sym.getComposition().getStage().myGlobalVar = 2;
And here's one way to create a global function:
// code on Stage.compositionReady
sym.myGlobalFunction = function(){
console.log('myGlobalFunction');
Then, anywhere in your project, you can call that function like so:
sym.getComposition().getStage().myGlobalFunction();

How to access a variable from within a symbol.

How do I access a variable set outside a symbol from within that symbol?
Thanks

If you set a variable on stage ,say
sym.setVariable("stageVariable", "I am stage variable");
You can access it from within a symbol using :
var myVariable = sym.getComposition().getStage().getVariable("stageVariable");
Basically you need to get handle to the symbol in which the variable is defined.

How to move images from Picasa to Lightroom 5 on a mac?

How to import images from Picasa to Lightroom 5 on a mac?

Hi, lnmyers,
I have thousands of pictures stored in Picasa, all of which are stored in my Picasa Web Albums. They are no longer in a directory on my hard-drive, that particular hard-drive having died ages ago. Thank goodness I uploaded them to Picasa's cloud before the hard-drive died. Should that ever darken, I am in trouble. I digress. I downloaded the pictures I wanted from Picasa Web Albums to my new external hard-drive that I set up and attached to my mac. For example: I had a an album called "California 2013" stored in the Picasa cloud. I downloaded the entire album to a folder on my Seagate external drive that I call Lightroom within which I have a folder called California 2013. It took about twenty minutes to get them all (300+ photos). Then, I pointed LR to the California 2013 folder on the Seagate external drive when I wanted to catalogue the pictures into LR. I did not worry about metadata; I took whatever came with the pictures and didn't worry about it. I added copyright, keywords, and ownership info with LR.
I hope that helps.

How to copy images from another MC in reversed order??

Hi everyone,
I'm new to AS3 and have been fighting and searching for a solution to this problem for a week now, and I'm VERY close!
I crated a MC holding of a series of images (about 50) and I jump around in it using plenty AS3 scripts (most of which I don't fully understand yet, but I'm working on that to! )
I had to find a way to "rewind" (= play backwards) the MC. Since there is a stop(); command in almost every frame, prevFrame does not work and if I put that in a loop, it goes WAY to fast (but worked).. So I could think of only one way...
Create a new (reverserd) MC with the same image sequence ald reverse it manually and play that one.
This all works fine (very proud of it ).
Now my question:
To get this to work for multiple image sequences, I have to load all images twice (once in MC_1 and again in MC_2 and select them and reverse them).
Not a big one, unless you want to create MANY of those SWF's...
Is it possible to load the 50 images of the first MC in reverse into the second MC dynamically? JUST the images, noting else.
extra info: the MC_2 is already in the lib(empty) and placed on the stage.
something like:
var pointer:Number=1;
for (var:i:Number=50;i>=0;i--) {
get MC_1.picure(var);
put it in MC_2.frame(pointer);
pointer = pointer + 1;
All help is welcome and please take into account that I have little experience and copy most of my scripting from people like you
T.I.A.
Melluw

I tried your advice (thanks for that)
The event I already have is the mouse leave
I //-d out the part I removed (what did work)
The code I ended up with is:
function Start() {
stage.addEventListener(Event.MOUSE_LEAVE, cursorHide);
function cursorHide(evt:Event):void {
var currFrame = MC_1.currentFrame;
if (CCW == true) { //it is true in this case
movStart = (50 - currFrame);
else {
movStart = currFrame;
if (movStart>25) {
MC_1.prevFrame();
// removed swapChildren(MC_1, MC_2); // This is the part I removed
// removed MC_2.gotoAndPlay(movStart);
else {
MC_1.gotoAndPlay (movStart);
And if I leave the stage on the part where movStart is indeed >25
Nothing happens,
So I guess this is not what you meant
Subject: Action Script 3 how to copy images from another MC in reversed order??
I cannot direct you in the loading of the images approach, it will be too complicated, and will probably not work anyways... when you move away from a frame that has dynamic content, you lose the content. So basically, there is nothing practical in taking that approach.
I do niot understand what the problem will be with the enterFrame/prevFrame approach. If everything you can do with the mouse is already used (which I doubt) by the first mc, then there is nothing else you can do with this file. You probably just need to rethink your control scheme. You should search Google for "AS3 slideshow tutorial", and to lighten up your design, add "XML" in that search.

What is the proper way to load images from css in Java 8?
Ref
How to load images from css file in JavaFX 8 - Stack Overflow

There is nothing special to do - you execute the statement from your program just like any other SQL statement. The only thing to be aware of are the privilege/permission issues:
When loading from a file on a client computer:
READ CLIENT FILE privilege is also required for the database user.
Read privileges are required on the directory being read from.
The allow_read_client_file database option must be enabled.
The read_client_file secure feature must be enabled.
Revoking these privileges is also the only way you can prevent a user from executing the statement.

What version of DW do you have. The later versions have RSS
script generators (I believe) for consuming feeds. Otherwise, you
can use 3rd party sites to generate the code, or you can use a
server side scripting language to consume the feeds.

Subject: the monitors of on location CS3 not showing image from Sony FX7
Breezley,
OnLocation CS3 used Direct Draw to create the video window. In Vista, you may have noticed that OnLocation CS3 would disable 'Aero' themed desktops as they did not support Direct Draw. Windows 7 does not have this functionality, so you must disable the Aero theme manually to see the video in OnLocation CS3.
To do this, right click on open desktop and choose Personalize.
This will display available Themes.
Scroll down to the 'Basic and High Contrast Themes'.
Choose any one of the basic or high contrast themes.
Restart OnLocation CS3.
This should bring your video back into view.
