File browsing based on image clicked

i'm becoming familiar with the File class, but i'm learning
very slowly and its difficult not to get frustrated. basically what
i want to do is be able to click on a map of different counties and
depending on which county is click, bring up an appropriate file
browser. so basically, the way i see it is that i need to take the
image and create hotspots on it. when a user clicks on that
hotspot, an event will be triggered to open the corresponding
folder. any help would be appreciated, thanks!

i'm not talking about the File Reference class, i'm talking
about the File class

any class that i can do this with will suit me of
course

File Browser doesn't display when Flex page is opened via showModalDialog IE9 on 64-bit system

From a html page, we open a flex page using showModalDialog.
Once flex page is launched, we have a button to open windows file browser.
When you click on the button, windows file browser opens as expected.
However, if you use IE 9 on 64-bit machines, windows file browser does not open and IE crashes.
If you use other versions and even IE9 on 32-bit system, file browser dialog shows up correctly.
When examining in flex code, the call to FileReference object's browse() returns true so I'm assuming Flex code is thinking browse window is opened.
We do not want to use showModalessDialog, is there any other soltuions to this issue?

File browser bug?

Ok, so here i got a problem with photoshop elements organizer 10 on Win 7 x64 pro
I press Crtl-alt-3 to open the file browser but when i click on the small arrow to open a sub-folder it bring me back to top of the file browser... since i got a lot of files... it's quite annoying to scroll back down each times to get a picture
I also looked on many forum but i didnt find anything about that... so whats wrong, is it a config in the option or a corrupted file and need a re-install or it is really a bug in the code... I also have done every up-to-date about the software
Thank you for considering my post

Try Ctrl+Alt+2 and see if it’s any easier to work with import batches, otherwise you need to simplify your folder structure. Better still use Ctrl+Alt+1 and work with keywords and albums, then it’s possible to use the full power of the Organizer by searching the entire catalog in thumbnail view.
In PSE 11 it’s possible to switch between the full folder tree and just the folders managed by Elements.

Error: Unable to locate an image file browser...

I get the error below when I insert an image element and try to associate a picture to it by either double clicking it or using the browse button in the Draw palette.
I have looked in my install directory and the "FileSystemBrowser.dll" file is present as well as the "ImageFileBrowserIDL.dll" file, so what gives?

How to add a new right-click menu entry in Nautilus file browser?

I want to add a couple of new context menu entries to Nautilus File Browser.
So when I e.g. right-click in View Pane on a file "foobar.conf" an menu entry "edit with gedit" should appear (among the other default entries).
When clicked the file "foobar.conf" should be passed to gedit (and gedit editor opened).
How can I achieve this?
Under Ubuntu there are nautilus-actions but when I try to install them in Solaris with
pkg install nautilus-actions
then this package is not found.
How else can I create my own context menues?
I would appreciate to have one script with all my context menus, which when run add them all in one step.

To manage selected files or directories, you can use specific Nautilus variables like NAUTILUS_SCRIPT_SELECTED_FILE_PATHS.
For more details and which variables exist, please read the content of the following URL :

Browser based AIR Help and PDF Files

Hi everyone,
I am so glad to have forum like this, hoping that sharing your experiences will help a little bit further.
Just recently I have tried to generate an browser based AIR Help in combination with merged projects. By the way, Peter Grainge's tutorial was very helpful here, thanks Peter!
My project also contained a single PDF file in a baggage container. After I had published my file, I had noticed that it was not possible to open the PDF in any way.
So I tried the same using the Adobe AIR Help Application and there the PDF worked. Now I was wondering whether I did something wrong or do I need to be aware of something.
Personally I don't mind using the Adobe AIR Help Application, the only disadvantage I had discovered beside the local installation, is the the document spacing seemed to be a little odd. Actually there was no space between the border and the content. With any other single source output there is, including the browser based AIR help.
I didn't find any similar problems on this forum, but maybe any of you has a little hint for me.
Thanks and greetings from Germany,
Christian

PDF should work from browser based AIR Help. Try a different file.
See the AIR topics on my site about the margins. In short, you create a copy of your CSS and just change the body tag margins in Notepad. Use the ordinary CSS when you are working or creating other outputs, use myproject_AIR.css when you generate the help.

Image Button file browser icon missing

Hi there, I've been using C5 this week for the 1st time and have been working through a project. All has gone ok to date, a few niggles along the way but I've run into a huge bug this morning which is wrecking my plan to finish the project.
I'm adding an image button to a slide and have found to my frustration that the file browser in Properties has vanished, pushed out past the properties block, which of course cannot be resized to the right (thanks Adobe, nice UI design there). This means I can't choose any image for my button apart from those already loaded in the preview which is utterly useless. I've attached a screenshot to show what it looks like.
As you can see the Image Button drop down has gone very wide and pushed the folder browser icon out of sight. Simply maddening!
I had been using image buttons all week with out any issues. Yesterday an update appeared (5.0.1.624) for C5 so I applied it. Then this issue started. I have since uninstalled C5 and reinstalled without applying the update and its still doing it. What I didn't do was reboot after the uninstall, maybe I should have done...
Anybody else come across this? if it is a bug its a crippling one!!!!

Hi Niall-Mac and KiHwa -
This is indeed a CP bug!!! We found this some months ago - it turns out that if you name your button images with a very long file name (35-40 characters plus), it slowly starts pushing the "browse" folder icon further and further to the right of the panel. Add a few more buttons with longer file names to the gallery and eventually it disappears altogether, like you both have encountered (see image).
Workaround 1 (best practice IMO until CP dev team fixes this):
We started creating buttons in a separate CP file, creatively named "projectName_buttons" - this way any time we need a button we go to this file and copy/paste it into our project and we never have to mess with the button gallery in our working (source) file. If the "browse" icon disappears again in our buttons file, we simply copy all our buttons from our "project_buttons" file into a new blank project and save over the old (broken) one.
Workaround 2 (not so user-friendly):
1. Stretch your timeline panel as wide as it can go on your monitor (I use two 21" monitors to develop so I can make my timeline rather long)
2. Undock the properties panel so that it is a floating window
3. Drag the properties panel by the topmost dark gray bar just above the "Properties" tab and place it just below the timeline until it snaps into place - now don't let go of it just yet, drag it up a tiny bit further - as you do this a blue bar will appear signifying that it will dock to that position (underneath the timeline) - when you dock it to the timeline it will stretch to the same length as the timeline and voila, you can now see the "browse" icon - however, who wants a properties panel that takes up your whole monitor!!!! I certainly don't.....
On a side note, it is very disheartening that once buttons are in the button gallery you have NO CONTROL over them - if they need to be edited you are forced to rename them so you can import a fresh button. This method unnecessarily creates TWO copies of a button in your gallery - the more edits you make to a button the more copies of that button you get in your gallery....some control over the button gallery would be nice.
Hope this helps.
Cheers,

My FaceTime seemed not working and keep telling me The document "IMG_3054.JPG" could not be opened. FaceTime cannot open files in the "JPEG image" format. I clicked OK but it pop-up again. So that I can't turn off my computer at all.

When I tried to restart my computer, FaceTime will pop-up and a warning message The document “IMG_3054.JPG” could not be opened. FaceTime cannot open files in the “JPEG image” format. I tried to clike OK but this worning message keeping pop-up and I can not quit FaceTime. So that I can't turnoff or restart my computer.
Can someone help?

The next time that happens, try this keyboard shortcut.
Command + Option + Esc
That way you can "force quit" the Facetime App.

Airhelp browser-based output won't open in network location

Hi,
Wondering if anyone can help us with the following issue:
I want to enable internal reviewers to open my browser-based AIR Help in a shared network location. Currently, in order to open the Help, reviewers must do the following (which seems rather complicated):
1. Create a folder on their local systems: \Macromedia\Flash Player\#Security\FlashPlayerTrust.
2. Paste into it the folder the RoboHelp.cfg file (containing the network path to my AIR Help index.html file).
I derived the above steps from the procedure provided by http://help.adobe.com/en_US/robohelp/robohtml/WS1b49059a33f77726-484da80912ce87f5f33-8000. html
Is there a way to avoid having to make reviewers perform these steps in order to access AIR Help on an internally shared network location?
Seems like a very involved process to just check to make sure others in the company can open it and test it. If they don't do this and they click on the index file it looks as if the help will open but then hangs on a blue grey box with a progress bar that never moves.
Thanks!

Hi there
Here's the fundamental issue. When you present WebHelp, it's just a frameset with some HTML pages, images and lots of javascript. Browsers generally have no issue with presenting that from local locations such as the C drive or network drives. Well, most browsers. IE will refuse things unless you enable Mark of the Web. When you present browser based AIR help, it's a similar setup, but the fancy looking elements are presented using Adobe Flash. Because you are running from local media and not a Web server, Flash Security kicks in and doesn't allow things to work until you pat it on the head and tell it the world, in fact, will NOT end if it shows you this content. That's what the config file does. Tells the Flash Player that it's okay if the content in this location is presented.
The thing is, if you run from your local drive and Flash Player didn't worry about security, folks could do some pretty nasty things to you if they wanted. That's why it exists. But if you run from a Web server, the browser automatically places you in a safe area. I believe in temporary files where things can't get out of hand. So there is no need for rigid security.
Cheers... Rick

Audio clip plays normal in Media Browser, but imports as "clicks" in session after saving & reopening.

This problem has happened with almost all of my large Audition projects. File links are intact & properly managed, and most audio files play as expected. However, some files in the session get replaced with this "click" track, for lack of a better way to describe it. The audio is literally replaced with a repetitive click, or pop sound, as you can see in the image below:
Both tracks had waveforms like the top track, but now the second track has been replaced with clicks.
The strangest part: The file in question, in this case: "Grass" (downloaded directly from Youtube Audio Library, so, not corrupt) previews perfectly fine in the Media Browser window. In the File Browser, however (tracks actually used in the session), it previews as nothing but clicks. When I try to then replace the track in the mixdown / file browser with the seemingly uncorrupted file in the Media Browser, it comes in as clicks!
The only thing I can think of is that the analysis files associated with the project are getting damaged?
Please help!

Can you send a copy of the Grass audio file to [email protected] and we'll take a look?

How to view stills as individual rather than sequences in file browser

i have a lot of stills, which happen to be numbered, and i need to browse them
for use in motion 3. the file browser is showing them as numbered sequences.
how can i defeat that behavior so i can see each individual image for import?
thanks,
BabaG

Right down at the bottom right hand side of the File Browser, you will see two buttons. Click on the left hand one that looks like rectangles receding into the distance.
That should fix it!

if you're simply trying to track extra info about the files you've uploaded into your wwv_flow_files view of wwv_flow_file_objects$, that's pretty well explained at File Download and somewhat at File Upload ( again! ) and Referencing Uploaded Files . if you're really trying to capture the path to the file as it was stored on your local machine at the time of upload, that's a much trickier matter. as opposed to a regular text field like...
<INPUT TYPE="text" NAME="p_t02" SIZE="30" MAXLENGTH="2000" id="P9_LOCAL_PATH" >
...File Browse item types use html like...
<input type="file" name="p_t01" size="30" >
...to facilitate this file upload stuff. after fiddling around a bit and talking to our UI guy, i'm currently under the impression that capturing the path to the uploaded file from your local machine is prevented by design. you might be able to use javascript to somehow trap the value shown on your screen before the upload occurs, but it didn't seem trivial after my cursory investigation. that's not to say that it's not possible, i just don't know the javascript off-hand.
hope this helps,

Using FMS v4.5.5 with a browser-based audio player running on iPad/iPhone

Hello,
I’m seeking some clarity/guidance on using FMS v4.5.5 (Streaming Edition) with a browser-based audio player running on iPad/iPhone (i.e. under iOS).
Background
I have a Microsoft Windows 2008 R2 Web Server running IIS v7.5 and supporting a website built using ASP.NET and C#. Parts of the website allow a visitor to play a selection of audio clips from our bespoke MP3 library. Due to UK music licencing constraints, we must stream the clip to the client browser – we must not download either part or all of the source MP3 file(s). We therefore had a custom audio player built for us some time ago using Flash/AS3. This has and continues to work very well, and uses RTMP to stream the clips from FMS to the client browser.
As our site has become more established the number of visitors has steadily grown. In the early days the number of visitors from the iOS platform was relatively small but, last month, it had risen to 40%! As Flash is not supported on the iOS platform, this growing group of visitors are unable to fully maximise the benefits offered by the website, which I am now trying to address.
What I’m Trying To Do…
From what I’ve researched and read, I believe that FMS v4.5.5 supports HLS and I need to use this (instead of RTMP) over HTTP between FMS and the iOS Safari client. I have been experimenting with an Open Source player (JPlayer) and a commercial player (JWplayer) and appear to have these playing a MP3 file as a “progressive download” (I think that’s the right term) as all I’m doing is specifying the file path (no HTTP prefix etc.), i.e. the audio is not really being streamed as I require. Unfortunately, I’ve not found / worked out how to configure my FMS to respond to a path request along the lines of:
http://www.myserver.com/live/audio1.mp3
Hopefully someone reading this who is much more expert on FMS, HLS, HDS, HTML5, etc. than me can point me in the right direction!
What I’m confused about…
1) Can all my MP3 assets stay as is and still be streamed to the iOS Safari client? To the best of my knowledge, the key properties of my MP3 files are CBR, 44,100Hz, 320Kbps.
2) If not, can they be converted on-the-fly by FMS or do I need to create additional audio assets to support HLS etc.?
3) If I have to manually create additional audio assets, how do I do that (I’ve seen references to tools from both Adobe and Apple but not actually found the kits)?
4) Some of the Adobe documentation I’ve read implies that FMS support for HLS etc. is only available when FMS is used in conjunction with the bundled Apache web server. As stated earlier, my entire site runs on IIS so does that mean to achieve what I want I’ll have to run two web servers on my physical server – IIS for the website itself and Apache for RTMP/HLS/etc.?
5) What changes do I need to make to my current FMS configuration to get HLS to work? I’m sure someone has been here already and can enlighten me with their experience and hopefully point me to some straight forward documentation to follow!
6) Lastly, and really part of (5), once I’ve got FMS configured correctly, what would be the typical path to a given MP3 audio file that I would give the iOS Safari browser to make this all work.
I appreciate this is rather a lengthy first post but hopefully the background puts my questions (and confusion!) in context. Bottom line is… I simply want to be able to stream audio clips only (no video) to iOS Safari browsers from FMS v4.5.5 running on a Win2K8R2 platform with IIS v7.5, and with no audio content being stored (even temporarily) on the iOS platform.
My thanks and appreciation in advance to anyone who can help me achieve this.

Hi Apurva,
Thank you for your reply. Unfortunately I am not much further forward, despite having read more Adobe documentation (FMS v4.5 Configuration and Administration Guide, FMS v4.5 Developer’s Guide) and trying different configuration options.
First to confirm a point you made when answering point 4 yesterday. Yes, in my current RTMP scenario I have several MP3 assets (let’s call them Audio1.mp3, Audio2.mp3, Audio3.mp3, etc.) that are made available to a bespoke Flash/AS3 player via the LIVE application. I understand that as I purchased the Streaming Edition of FMS v4.5, a Flash-based player is restricted to using the LIVE application. You go on to say that I “publish” these assets to the LIVE application. I set this up a while back but do not recall having to “publish” anything. All I recall doing was to ensure that all the assets (the .mp3 files) were in a single folder and that the folder was identified by the <Streams> tag in the following file (example shown):
Flash Media Server 4.5\applications\live\Application.xml
                <StreamManager>
                                <VirtualDirectory>
                                                <Streams>/;C:\MP3Library</Streams>
                                </VirtualDirectory>
                </StreamManager>
To the best of my knowledge, I didn’t have to do anything else to make the current solution work. Having read more of the documentation I am still none the wiser as to what I need to do (step-by-step) to “publish” my converted MP3 assets (see next paragraph) to the LIVEPKGR application. Please could you explain these steps to me by way of an example.
WRT your answer to point 1 yesterday, I wish to clarify the exact output I need to create when converting my MP3 assets. Am I expected to produce a Audio1.aac file, or a Audio1.mp4, file, or a Audio1.m4a file, etc.? Or am I meant to be using ffmpeg (either directly or indirectly) with a much more sophisticated command line that somehow generates stream-rated info/files as well? An example of how you would use ffmpeg to convert one of my MP3 assets would be very much appreciated.
Lastly, the coexistence of IIS and Apache (ref your answer to point 2 yesterday). That all made sense but given all the testing/changes I’ve been making I thought it wise to start afresh! So I completely removed FMS from my dev server and re-installed Flash Media Streaming Server v4.5.5 with the bundled Apache v2.2 server. When presented with the dialogue “Would you like for Apache to listen on port 80. If not FMS will be using port 80 instead.” I answered NO. When presented with the dialogue regarding FMS server ports, I entered 1935 NOT 1935,80 (should I have done that as the preamble makes reference to HTTP webserver proxy and HTTP Dynamic Streaming origin services?). I then modified the Application.xml file as described above.
To test the new set-up, I did the following. First, the test environment…
DEV Server
Windows Web Server 2008 R2 SP1
IIS v7.5
ASP.NET v4.0
Flash Media Streaming Server v4.5.5
Apache v2.2
IE v9.0
Adobe Flash Player 11 ActiveX v11.5.502.146
TEST Client
Apple iMac (Intel)
Mac OS X v10.6.8
Safari v5.1.7
Adobe Flash Player 11 Plug-in v11.5.502.146
On DEV Server… launched IE and loaded the home page of my website, which has two elements on it – one to load/run our bespoke Flash player, the other to run JPlayer (configured to use HTTP). I selected our bespoke Flash player and it played a MP3 audio file. I verified this in real-time via the FMS Admin Console on the server.
On TEST Client… entered http://192.168.20.250:8134 into Safari – it comes up with the FMS install completed / test your server page. In the middle of the video display area a black box appears saying “10000 OK” – I clicked OK. I then clicked HDS Single Bitrate – the video plays (Not Using Hardware Acceleration is briefly displayed). There is NO activity logged in the FMS Admin Console back on the DEV server under “live”, “livepkgr” or “vod”. I assume this is because I’ve gone straight to the Apache Server via the port reference – is that correct? Next I tried the HLS Single Bitrate – same results.
The HDS Single Bitrate logs the following in the Apache access_log file:
"GET /hds-vod/sample1_1500kbps.f4v.f4m HTTP/1.1" 304 - "-" "Apple Mac OS X v10.6.8 CoreMedia v1.0.0.10K549"
The HLS Single Bitrate logs this:
"GET /hds-vod/sample1_1500kbps.f4v.f4m HTTP/1.1" 304 - "-" "Apple Mac OS X v10.6.8 CoreMedia v1.0.0.10K549"
"GET /hls-vod/sample1_1500kbps.f4v.m3u8 HTTP/1.1" 304 - "-" "Apple Mac OS X v10.6.8 CoreMedia v1.0.0.10K549"
"GET /hls-vod/sample1_1500kbps.f4v.m3u8 HTTP/1.1" 200 816 "-" "Apple Mac OS X v10.6.8 CoreMedia v1.0.0.10K549"
"GET /hls-vod/sample1_1500kbps.f4vFrag1Num0.ts HTTP/1.1" 200 1143416 "-" "Apple Mac OS X v10.6.8 CoreMedia v1.0.0.10K549"
"GET /hls-vod/sample1_1500kbps.f4vFrag1Num1.ts HTTP/1.1" 200 873072 "-" "Apple Mac OS X v10.6.8 CoreMedia v1.0.0.10K549"
"GET /hls-vod/sample1_1500kbps.f4vFrag2Num2.ts HTTP/1.1" 200 1591984 "-" "Apple Mac OS X v10.6.8 CoreMedia v1.0.0.10K549"
etc…
At this point I’m stuck once again since I’m not clear how to construct the JPlayer HTTP reference. You have suggested:
http://192.168.20.250:8134/hls-live/livepkgr/_definst_/livestream/livestream.m3u8
That produces the following in the Apache error_log file:
[error] [client 192.168.20.4] File does not exist: D:/Program Files/Adobe/Flash Media Server 4.5/webroot/hls-live
If I change the JPlayer HTTP reference to:
http://192.168.20.250:8134/hls-vod/sample1_1500kbps.f4v.m3u8
the audio from the video plays.
Also, if I look in the applications\livepkgr folder structure there is only \events (with sub-folder _definst_ and sub-sub-folder liveevent) – there are no _definst_ , livestream , streams folders etc. So besides me not quite understanding the logic/flow here, I seem to be missing a few folders/files too! I’d be very grateful for any light you can shed on all this. Plus an example of what my HTTP string should ultimately look like; for example:
http://192.168.20.250:8134/hls-live/livepkgr/_definst_/livestream/Audio1.m3u8
Apologies for such a long reply but I’ve been at this for over 10 hours today! I feel I’m getting closer but clearly there are still some gaps and configuration errors.
Thanks again for your time, support, patience and understanding.
Kind Regards, Steve

Browse to source image not letting me change images on a page

So - say I have an image on a page; let's call it "one.jpg". If I want to replace it with "two.jpg", I would normally just click the little folder icon in the properties menunext to the Src field, and choose the new image. Done it a million times.
But now when I do that - the image doesn't change (that is to say - the name in the "Src" field remains the same, as does the image on the page). I can manually type in "two.jpg" or I can use the little "point to file" thing next to the folder icon - but no dice doing a simple browse image.
The browse image function works normally when putting in an image for the first time - it's just when I want to change the image that this happens (or rather - doesn't happen). Anyone experienced this?
thanks…
Dave

"Browse to file" not updating existing images or links is a well known bug in CS4.
http://forums.adobe.com/message/2505480
http://forums.adobe.com/message/2564640
The workarounds are:
1) type the filename (as you have found) but that's a painful productivity killer
or
2) after clicking "Browse to file", browse up or down a folder level first then browse back to the new image that you want to change to. This "wakes" Dreamweaver up so that the correct file and path is changed.
No patch was ever issued for CS4 for this issue but it is fixed in CS5.
