Best strategy for flash access to an image in a protected folder

hello all,
i'm looking for a good strategy for my swf to be able to load
images in a password protected directory. since flash can't access
a file behind a protected folder i figure i'll use php to get the
image and pass it to flash.
how best to get an image from php to flash since i can't just
send a path to a file and have flash execute a Loader() to retrieve
it since the Loader won't be able to get behind the protected
folder?
is it best to have php send the file binary to flash that
flash will receive via URLLoaderDataFormat.BINARY? is it best to,
at runtime, have php move the requested file from the protected
folder to an unprotected folder and after flash loads it then
delete it from the unprotected folder? maybe it's best to leave the
image folder unprotected and let an .htaccess redirect restrict
outside access to the folder?
suggestions?
tia,
michael

The built-in Firefox Sync service allows you to store your settings, including bookmarks, on a Mozilla server. This isn't accessible as a file like Google Drive; it can only be used by connecting another copy of Firefox to your Sync account. You can read more about this here: [[How do I set up Firefox Sync?]] (I haven't tried it myself since it changed recently.)
The cross-browser Xmarks service is more focused: it just does bookmarks. http://www.xmarks.com/ (I've never tried this one either)
If you prefer working with files and you have a Dropbox or similar account, you could in theory back up your Firefox profile folder, or more particularly, the bookmarkbackups subfolder. I haven't tried that myself. To find the folder:
Open your current Firefox settings (AKA Firefox profile) folder using either
* "3-bar" menu button > "?" button > Troubleshooting Information
* Help menu > Troubleshooting Information
In the first table on the page, click the "Show Folder" button
A window should launch showing your currently active settings files. The bookmarkbackups folder should contain dated .json files which can be used to restore your bookmarks to another copy of Firefox.
Alternately, someone might have created an add-on for saving Firefox bookmarks to the cloud another way, but I haven't heard of one.

  • Best strategy for migrating GL 6 DW CS4?

    First I gotta say that -- as decade-long user of several Adobe products -- Adobe has really screwed over long-time users of Adobe Golive. After a week of messing around with something that should be a slam dunk (considering the substatial amount of $ I've paid to Adobe over the years for multiple copies of GoLive 5, 6 and CS2), I can tell you Adobe's GL > DW migration utility ONLY works for sites created FROM SCRATCH in GL CS2 (they must have the web-content, web-data folder structure). This means that Adobe's migration utility only works for maybe 10% - 15% of the GoLive sites out there, and about 10% - 15% of Adobe's loyal GoLive customers, and it particularly screws over Adobe's longtime GoLive customers. Sweet! ( (Just like Adobe screwed over users of PhotoStyler -- which was a better image editor than PhotoShop, BTW.) Obviously, I would walk away from Adobe and make sure I never ever paid them another cent, but the Republican-Democrat "free market economy" has made sure I don't have that option.
    So I've gotta make Dreamweaver work, which means I've gotta migrate several large sites (the biggest has 5,000 static pages and is about 2 gigs in size) from GoLive 6 (or GoLive CS2 with the older folder structure) to Dreamweaver CS4.
    Which brings me to my question -- what's the best strategy for doing ths? Adobe's migration utility is a bad joke, so here's the alternative, real world plan I've come up with. I'd apreciate any suggestions or comments...
    1) create copies of all my GL components in the content folders for my GL site (not in the GoLIve components folder)
    2) replace the content of all GoLive compnents (in the GoLive components folder) with unque character strings, so that instead of a header with images and text, my old header would look something like xxxyyyzzz9
    3) create a new folder called astoni in the root of my hard drive. Copy all my GoLIve web site content (HTML, images, SWF, etc.) into astoni in exactly the structure it was in with GL
    4) create a new Dreamweaver site by defining astoni as the local location for my site, astoni\images as the location for images, etc.
    5) use Dreamweaver and open the newly defined astoni site. Then open each of the GoLive components I copied into a content level folder in astoni, and drag each into the Dreamweaver Assets/Library pane, in order to create library items just like my old GoLive components
    6) use Dreamweaver to Search & Replace out the unique text strings like xxxyyyzzz9 with the content of my new DW library items
    7) refresh site view to make all the links hook up...
    Thanks for your help. Hope this discussion helps others too...

    Instead of ragging on people who are familiar with DW and Site Development, you should be gracious and accept the practical advice you've been given.  A "best strategy" would be to read some tutorials and learn how to work with HTML, CSS and server-side technologies. Without some basic code skills, you're going to find DW an uphill, if not impossible battle.
    Frankly, I don't have free time to hand-hold someone through the excruciating process of migrating a 5,000 page static site from GoLive  to DW. And I doubt anyone else in this forum has either.  We're not Adobe employees.  We don't get paid to participate here.  We are all product users JUST LIKE YOU.
    I'm sorry you're frustrated.  I'm also sorry for your clients. But the problem you have now isn't Adobe's fault. It's yours for not keeping up with server-side technologies or handing-off these huge static sites to more capable web developers.  I'm not saying you need to buy anyone's books, but they are good resources for people willing to learn new things.
    That said, maybe you should stick with GoLive.  The software doesn't have an expiration date on it and will continue working long into the future.  If you're happy using GL, keep using it to maintain your legacy sites. At the same time learn X/HTML, CSS & PHP or ASP.  Use DW CS4 for the creation of new projects.

  • Best strategy for buring dual layer DVD

    I've got a project that won't fit on a single layer DVD, so I've got it set up for dual layer and "best quality" which results in a 7.38GB disk image.  However, iDVD 8 warned me when burning the disk images that some utilities may not be able to burn a reliable dual layer disk copy and to use iDVD instead, does this include Disk Utility?
    I always use Disk Utility to make copies, iDVD took almost 7 hours to burn the disk image, I can't afford to wait that long for each copy.  So what's the best strategy for burning dual layer DVDs?

    subsequent copies burn in far less time immediately after the first provide you don't quit iDvd
    If you know ahead of time you'll need more than a few copies, I'd recommend burning from a disc image to the desktop and reducing the burn speed (4x or lower) I prefer to use Roxio Toast myself. But others have had success with Apple's Disc Utilities as well.

  • Absolute Best Strategy for Cropping

    What's the absolute best strategy for high precision cropping when time is not an issue and and want "perfect" quality?
    What's the absolute best strategy for low precision cropping when time is an issue and standards are still high?
    There's gotta be different strategies for doing this, and I was curious if we could choose a winner.
    Thanks,

    Heh, Marian, that about sums it up. 
    In all seriousness...  How does "precision" connect with "cropping"?  I've always thought of "cropping" as most based on an artistic judgment, not something done for precision.  Perhaps you could describe your photography and what you expect from your workflow?
    Are you cropping photos of documents?  People?  Stars, nebulae, and galaxies?
    Is this "precision" you speak of an attempt to express "minimal loss of pixel data"?  If that's the case, get the most powerful computer you can and always work at upsampled resolutions.  And don't resample during cropping.
    One last comment:  Consider employing the crop tool in the Camera Raw dialog.  This stores metadata telling future conversions how to crop the image, but the original raw data is still all intact.  Note that you can open a whole set of images in Camera Raw, do exposure and cropping changes, and click [Done] to save that metadata.

  • Best strategy for variable aggregate custom component in dataTable

    Hey group, I've got a question.
    I'd like to write a custom component to display a series of editable Things in a datatable, but the structure of each Thing will vary depending on what type of Thing it is. So, some Things will display radio button groups (with each radio button selecting a small set of additional input elements, so we have a vertical array radio buttons and beside each radio button, a small number of additional input elements), some will display text-entry fields, and so on.
    I'm wondering what the best strategy for tackling this sort of thing is. I'm sort of thinking I'll need to do something like dynamically add to the component tree in my custom component's encodeBegin(), and purge the extra (sub-) components in encodeEnd().
    Decoding will be a bit of a challenge, maybe.
    Or do I simply instantiate (via constructor calls, not createComponent()) the components I want and explicitly call their encode*() and decode() methods, without adding them to the view tree?
    To add to the fun of all this, I'm only just learning Faces (having gone through the Dudney book, Mastering JSF, and writing some simpler custom components) and I don't have experience with anything other than plain vanilla JSP. (No EJB, no Struts, no Tapestry, no spiffy VisualDevStudioWysiwyg++ [bah humbug, I'm an emacs user]). I'm using JSP 2.0, JSF 1.1_01, JBoss 4.0.1 and JDK 1.4.2. No, I won't upgrade to 1.5 (yet).
    Any hints, pointers to good sample code? I've looked at some of the sample code that came with the RI and I've tried to navigate the JSF Blueprints stuff, but I haven't really found anything on aggregating components into a custom component. Did I miss something obvious?
    If this isn't a good question, please let me know how I can sharpen it up a bit.
    Thanks.
    John.

    Hi,
    We're doing something very similar. I had a look at the Tomahawk Date component, and it seems to dynamically created InputText components in the encodeEnd(). However, it doesn't decode this directly (it only expects a single textual value). I expect you may have to check the request yourself in decode().
    Other ideas would be appreciated, though - I'm still new to JSF.

  • What's best strategy for dealing with 40+ hours of footage

    We have been editing a documentary with 45+ hours of footage and presently have captured roughly 230 gb. Needless to say it's a lot of files. What's the best strategy for dealing with so much captured footage? It's almost impossible to remember it all and labeling it while logging it seems inadequate as it difficult to actually read comments in dozens and dozens of folders.
    Just looking for suggestions on how to deal with this problem for this and future projects.
    G5 Dual Core 2.3   Mac OS X (10.4.6)   2.5 g ram, 2 internal sata 2 250gb

    Ditto, ditto, ditto on all of the previous posts. I've done four long form documentaries.
    First I listen to all the the sound bytes and digitize only the ones that I think I will need. I will take in much more than I use, but I like to transcribe bytes from the non-linear timeline. It's easier for me.
    I had so many interviews in the last doc that I gave each interviewee a bin. You must decide how you want to organize the sound bytes. Do you want a bin for each interviewee or do you want to do it by subject. That will depend on you documentary and subject matter.
    I then have b-roll bins. Sometime I base them on location and sometimes I base them on subject matter. This last time I based them on location because I would have a good idea of what was in each bin by remembering where and when it was shot.
    Perhaps, you weren't at the shoot and do not have this advantage. It's crucial that you organize you b-roll bins in a way that makes sense to you.
    I then have music bins and bins for my voice over.
    Many folks recommend that you work in small sequences and nest. This is a good idea for long form stuff. That way you don't get lost in the timeline.
    I also make a "used" bin. Once I've used a shot I pull it out of the bin and put it "away" That keeps me from repeatedly looking at footage that I've already used.
    The previous posts are right. If you've digitized 45 hours of footage you've put in too much. It's time to start deleting some media. Remember that when you hit the edit suite, you should be one the downhill slide. You should have a script and a clear idea of where you're going.
    I don't have enough fingers to count the number of times that I've had producers walk into my edit suite with a bunch of raw tape and tell me that that "want to make something cool." They generally have no idea where they're going and end up wondering why the process is so hard.
    Refine your story and base your clip selections on that story.
    Good luck

  • Best export for flash video

    I have completed an edit of a 7 minute teaser for a feature film and need to export it to be displayed online in a flash player. The footage is HD 1080i, 29.97fps and edited in the Animation coded. My experience with best exports for flash conversion is very limited so please bare with with.
    1) Is it possible to export directly from FCP to a flash file? If yes, would that be a good idea, or should I use third party softwares for better results?
    2) Which third party softwares are recommended for flash conversion? And what export compression should I use in FCP for best flash conversion results?
    3) Any other tips and tricks to get the best quality for flash video display?
    Any help would obviously be greatly appreciated. Thank you.

    When I have quality HD video that I want to export for flash, I compress it with h.264 codec. Then, with the new version of Flash, you can swap out the .mp4 extension for .f4v and your good to go in Flash. Quality looks pretty good at a fraction of the file size.

  • What's the best method for a nav menu with image rollover for all visitors?

    Hi.
    First, thanks for reading this.
    What's the best method for a nav menu with image rollovers for all visitors, including PDAs? I've used JavaScript rollovers for years because the majority of my customers' visitors use some version of IE (past 7.0) but I'm building a new site that has to display properly for the widest range of visitors imaginable. (I also know that I need to use a more modern method for everyone and this is my excuse to start).
    Finally, using images is critical. I apologize ahead of time to anyone I offend, but I have never seen a nav menu without images that doesn't look just plain terrible.
    Thanks.

    If you want the best menus possible for Dreamweaver look no further than Project Seven:
    http://projectseven.com/
    They have all kinds of menus and other extensions available for purchase.  Easy to use and they work as advertised.  I personally use Pop Menu Magic and Tab Panel magic myself.  I could go on and on, but I guarantee that if others respond they will echo the same sentiment for Project Seven.

  • Available HTTP delivery options for Flash Access encrypted content

    Dear colleagues,
    Could you please clarify available HTTP delivery options for Flash Access encrypted content.
    Standard HTTP DS scheme with Apache web server getting chunks of video from segmented with f4fpackager file.
    HTTP Progressive Download of encrypted with Flash Access file (non segmented).
    Is it possible to use byte range delivery in this case in order to start playback from custom position (seek)?
    Are there any pitfalls in this case? Is it required to make encryption blocks aligned with keyframe intervals or something like that?

    Thanks for your response, seems though that only the encrypted videos appear to have a problem because when I tried some un-encrypted videos (again from adobe http://drmtest.adobe.com/content/unencrypted/Indesign.f4v ) it played fine.
    Maybe is has something to do with the decryption process and the hardware of the mobile phone after all.
    Again thanks for your response.

  • Best strategy for importing organized images

    Hello,
    I have recently started using Aperture in my photography workflow and I need some advice from the experts on the best strategy to import the existing .JPGs from my hard disk into my Aperture library.
    Prior to using Aperture, my workflow was as follows:
    1.) I would import ALL the photos from my digital camera to a folder on my hard disk (one folder for each date of import). These, in effect, were my 'master' images, which I never edited or deleted.
    2.) Next I would make a copy of each new master folder, under a separate folder called 'picks', where I would go thru and delete the bad ones and occasionally make some minor edits or crops to the good ones. These 'picks' folders are what I used for my slideshows, photo galleries, etc.
    NOW, as I'm moving everything to Aperture, I'm attempting to find the best strategy to import everything, where I would maintain both a master copy of everything that came off my camera and the already organized 'albums' of 'versions' the represent my 'picks', but also reduce some of the redundancy of having duplicate copies of 60-70% of the photos in my library.
    Here is where I need some advice. In the case of new photos imported directly from the camera into Aperture I have managed to figure out how to import the master images and then create albums of versions for my good pics. However, I haven't found any way to import my existing masters and picks without importing two copies of each "good" pick.
    Is there any way I can get Aperture to recognize that the photos in my 'picks' folders are actually 'versions' of some of the original 'masters' so I don't need to import two master copies of each of my good pics? (I generally left the file names the same.)
    I have several thousand existing pics on my hard disk that I'm hoping to import into Aperture so I'm hoping there is an efficient way to do this!
    Many thanks for the help!

    HI I would also be interested in how others do this. I have been playing with aperture for some time and I am still not sure whether to commit to it.
    I also keep my masters in a folder structure with year at the highest level and day of shooting below that.
    I know its not necessary to do this in Aperture but I am not sure I understand why or if its a bad thing to do.
    Would love to her what others think and advise.
    Thanks

  • Best Strategy for Exporting Fireworks into Dreamweaver

    I created a navigation bar in Fireworks and now I want to export it into Dreamweaver.
    So I Went to Edit->Copy HTML Code (hotkey for this is Ctrl+Alt+C)
    Now, what's the "best choice" from the dialog choices: AIR HTML, Dreamweaver HTML, Generic HTML, GoLive HTML, AIR XHTML, Dreamweaver XHTML, Generic XHTML or GoLive XHTML for a cross browser "professional" website?
    I only tried the "Dreamweaver HTML Option" and itseemed to work nicely in my rookie opinion.
    I think this technique might be at a performance cost to my graphic design or the website speed. So should I use a different strategy for exporting Fireworks to Dreamweaver?  I have the CS5 package so can use any of those programs for support.
    Thanks,

    INHO, the best way to export from Fireworks to Dreamweaver is to first define your site in Dreamweaver, and then export the Fireworks document to the assets folder. Place your cursor when you want the navbar to be on your HTML page and choose Insert > Image Objects > Fireworks HTML.

  • Best strategy for my flower logo?

    Hi, I am attempting to create a logo of a pointy-petaled flower and am not sure of the best approach.  My .ai file in cs3, cs4, and cs5 formats may be found here:
    http://207.210.251.84/pub/
    At first I started tracing around the petals using the pen tool and quickly decided that this woudln't be the best way to go for a logo.  Then I realized that the flower is basically a sphere with petals which are like rays that emanate from the center.  The petals vary for the most part only in their direction (and shadow).
    So I drew a circle which later I think I'll use to employ some combination of gradient transparancy, and then I drew straight lines from the center.  I think that I will want to vary the width of each line (one done for demostration) but the problem is that there is only one stroke color, no fill possible.  I would also like to have each petal use more than one color (for example, the tip should be a lighter color than the parts below).
    Can anyone offer a newbie a strategy for doing this?  Should I make one petal how I like it, using overlapping line segments (with different width tool profiles and different stroke colors), and then turn that into a symbol which would be duplicated, rotated and stretched to match the angles and lengths of the plain straight lines that you see ?
    I have been through Deke's 1-1 fundamentals at Lynda.com, and I have access to the Advanced/Mastery courses, which is where the symbol/gradient/transparency topics can be found (though I have not examined them yet). 
    Thank you in advance for any advice you can provide!   It may be premature, but I am also going to probably try simulating a light source similar to that in the original pic

    Keep in mind that something to actually be used as a "logo" should usually be very simple, and boiled down to clean, tidy, and efficient normalized paths.
    That said, this is just to demonstrate ways to exploit transformations, Blends, and Symbols to quickly genereate a bird's-eye-view of a "clustered" construct like a bloom, bush, or whatever:
    With any of these, you can also generate "different" ones by simply applying the same Transform Each command again, to randomly change the rotations of the petals.

  • Best strategy for data definition handling while using OCCI

    Hi, subject says all.
    Assuming to use OCCI for data manipulation (e.g. object navigation), what's the best strategy to handle definitions in the same context ?
    I mean primarily dynamic creation of tables and columns.
    Apparent choices are:
    - SQL from OCCI.
    - use OCI in parallel.
    Did I miss anything ? Thanks for any suggestion.

    Agreeing with Kappy that your "secondary" backups should be made with a different app. You can use Disk Utility as he details, or a "cloning" app such as CarbonCopyCloner or SuperDuper that can update the clone periodically, rather than erasing and re-copying from scratch.
    [CarbonCopyCloner|http://www.bombich.com> is donationware; [SuperDuper|http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html] has a free version, but you need the paid one (about $30) to do updates instead of full replacements, or scheduling.
    If you do decide to make duplicate TM backups, you can do that. Just tell TM when you want to change disks (thus it's a good idea to give them different names). But there's no reason to erase and do full backups; after the first full backup to each drive, Time Machine will back up only the changes made since the last backup +*to that disk.+* Each is completely independent.

  • Best Strategy for Integrating Crystal/Business Objects with OpenACS Environment

    Post Author: devashanti
    CA Forum: Deployment
    I'm working for a client that uses AOL server and OpenACS for their web services/applications. I need suggestions on the best strategy to integrate a reporting solution using Business Objects XI. Ideally I'd like to send an API call from our web application's GUI to the Crystal API with report parameter values to pass into specific reports called via the API - I can get it down to one integer value being passed - or if this is not possible a way to seamlessly, from the end user perspective, move into a reporting module. We are using an Oracle backend database. I'm experienced with creating stored procedures and packages for reporting purposes.
    Although I have many years of experience integrating the Crystal active X controls into n-tier client server applications, the past few years I have had little opportunity to work with Business Objects and the newer versions of Crystal or web based solutions with Crystal Reports. I signed up to try out crystalreports.com, but I doubt my client will find this solution acceptable for security reasons as the reports are for an online invoicing system we are developing. However we can set up a reports server in-house if necessary, so it gives me some testing ground.
    Can anyone provide suggestions for a doable strategy?

    Please post this query to the Business Objects Enterprise Administration forum:
    BI Platform
    That forum is monitored by qualified technicians and you will get a faster response there. Also, all BOE queries remain in one place and thus can be easily searched in one place.

    For simply two databases, there really wouldn't be a need for a recovery catalog. You can still restore/recover without a controlfile and without a recovery catalog.
    From this:
