Displaying image from a byte array
Please i need display an image from a byte array. The byte array contains a fingerprint image captured from the fingerprint device. I am using the java class from coldfusion, i am having problem displaying the image from the byte array. The fingerprint device is Secugen Hamster plus should anyone have integrated it with coldfusion. Thanks. ~| Want to reach the ColdFusion community with something they want?

Re: Displaying image from a byte array
Is it a Java buffered image? If so you can pass it to ImageNew(). Have you tried that?

Re: Displaying image from a byte array
Ray should be right. I've passed raw image byte data from flex to coldfusionjedi with no problem. If you're receiving the data in a cfc just type the argument as binary.

Search emails dynamically from a cf8 app
I'm thinking about providing an ability to search all emails for a user (from his/her pop3 server) while performing a search for some texts from the current app/ current database. Yes, understand the cfpop tag would allow one to connect to a pop3 server and retrieve emails dynamically. But say, an average user's inbox would have ~800 emails. I'm not sure how efficient this approach of pulling out ~800 or more emails and then run a query against it. Am thinking loud here, how about Event Gateway (have never used it though)? Wouldn't it be a more direct hence more efficient approach? app - connector -- event gateway setup and process (search against the entire inbox for the user for a keyword/phrase) -- pass results back to app ? is it something like that? Thanks for your time. ~| Want to reach the ColdFusion community with something they want?

Apparently you can also pass in the image bytes directly, without using a Bufferedimage. ie ImageNew(byteArray) I cannot believe I never knew that one. -Leigh ~| Want to reach the ColdFusion community with something they want?

Re: Is this possible with component methods in cf8?
If you have the files in a loopable deal, I don't see why you couldn't loop over them, outputting the current index, and doing a cfflush after each iteration? It's corny and easy and not ajaxy, but theoretically workable. -- There is nothing in which the birds differ more from man than the way in which they can build and yet leave a landscape as it was before.

I didn't actually want a loading progress indicator in terms of something that shows how much of a file has uploaded. I just want to return the info after each file has finished loading and processing, but doing so over and over until all the photos were processed. I was thinking of something that would simply tell the user that photo xyz had finished uploading, various sizes had been created, etc., after the that process finishes for each photo. Just some kind of running notifications to keep them in the loop on what's happening. (And that something is *still* happening, so they don't bother the browser). After initiating a multiple photo uploading, the user would get something like this: (a few seconds pass, then, via ajax, display...) - photo01.jpg has been uploaded and thumbnails have been created (a few seconds pass, then, via ajax, display...) - photo02.jpg has been uploaded and thumbnails have been created (a few seconds pass, then, via ajax, display...) - photo03.jpg has been uploaded and thumbnails have been created etc., etc., until all submitted photos have been uploaded and processed. I just couldn't think of a way to return info such as the uploaded file name, etc., from a component method, *multiple times*. I thought perhaps I could somehow *loop* the image process routine, *including* the cfreturn, so I could get info back to the browser. I didn't know if that were possible, so I thought I'd just ask before starting trying to code a solution that might not even be possible. Perhaps I could somehow use a couple of processing methods that do the same thing, and when one is finished, have it return info for an image processed, and then trigger then second method to process an image and return info, which then triggers the first to process another photo, etc., until all the photos were processed. I don't know...just trying to think of a way to get this done using component methods or even another way. R ~| Want to reach the ColdFusion community with something they want?

Re: Search emails dynamically from a cf8 app
Am thinking loud here, Excuse the intrusion into your loud thinking but that is not a question that can be answered with out asking more questions. Could you do me (and I assume others) a favor and ask a question that be answered with out people having to asking questions in order to provide an answer? For instance. Read your question, and then ask the questions that you would need to ask in order to provide an answer, and then ask THAT question. That would help a lot.

No, an event gateway wouldn't be any more direct. It would, in fact, be less direct - instead of CF talking to the mail server, something else would have to talk to the mail server. I don't think that searching POP mailboxes from CF is an especially good idea. If possible, I would fetch mail from the mailboxes periodically, and index that using Verity (or Solr or whatever). Or better yet, ditch the POP mailboxes entirely and switch to Google Apps, which is in my opinion better in almost all respects to hosting your own mailserver or using an ISPs server or whatever. Of course, being a Google Apps reseller/implementer/trainer I may be slightly biased. Google mail is easily searched, as you can imagine, and I think it would be pretty easy to get CF to provide an interface for that search if you want it.
