Re: CF Image question...
The thing I wish it would do is add a permanent watermark on uploaded images instead of only on temp png while being shown. You can do this: 1. Read in original image 2. Read in watermark image (transparent GIF) 3. Set transparency of watermark image to 20-30% Either: 4. Mathematically locate position of watermark OR 4. Resize watermark image to size of original (in memory) THEN 5. Overlay watermark image on original image FINALLY 6. Rewrite original image to drive. This is something that can take the server some time to do - I would suggest using asynchronous processing or scheduled task to handle this.

CFPARAM doesn't work as expected
In Applicationb.cfm I have these lines:
cfparam name=APPLICATION.objects.security
default=#CreateObject('component','components.security').init(authorization='public',language=Left(CGI.HTTP_ACCEPT_LANGUAGE,2))#
cfparam name=APPLICATION.objects.util
default=#CreateObject('component','components.util')#
cfparam name=APPLICATION.objects.db
default=#CreateObject('component','components.db').init(dsn='irama',maxStringLength=25)#
cfparam name=APPLICATION.objects.cms
default=#CreateObject('component','components.cms').init()#
First time the page gets requested, there's nothing in the APPLICATION scope so
the lines CreateObject().init*() are executed. On subsequent calls the
APPLICATION scope contains all the objects so I expect that the default values
(CreateObject().init()) don't get assigned.
But they do! I put a cfdump in the init handler and _every_ time a page gets
requested it gets executed. So every time my objects get initialized and
previous data is lost.
I thought cfparam only assigns the default value if the variable doesn't exist
but here it executes it every time.
Is this a bug or as designed?

Re: CF Image question...
This is something that can take the server some time to do - I would suggest using asynchronous processing or scheduled task to handle this. We ran into some issues at my day job trying to use cfthread for resizing images, realizing that if you're doing a lot of it, you can run out of threads in the cfthread pool and the remaining cfthread tags will error out if they don't get access to a thread fast enough. So one alternative that would allow you to resize the images when the user uploads them (no scheduled task) without slowing them down would be to return content to the browser prior to your image editing, i.e. /body /html cfflush / cfimage ... / I do this occasionally in the onRequestEnd (function / template). The drawback is that you can't use cflocation after the cfflush tag to redirect the user if you're going to do that -- and at least with any recent version of ColdFusion you can't use cflocation before any code you want to execute. So if you wanted to redirect the user this way, you would want to use either a meta tag or javascript in the content before the cfflush tag. (and I would include a continue link also) Another alternative would be to use cfhttp / to spawn a request for a page in your application that performs the image manipulation without waiting for the http result content. I'm told there is a way to use cfhttp (a particular timeout value I think) in which ColdFusion doesn't wait for the response, although I haven't personally used it. This way you could span the http request and then redirect the browser with cflocation if you want. hth, ike -- s. isaac dealey ^ new epoch isn't it time for a change? ph: 503.236.3691 http://onTap.riaforge.org ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295339 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

RE: CFPARAM doesn't work as expected
I thought cfparam only assigns the default value if the variable doesn't exist but here it executes it every time. I would recommend that you not use CFPARAM in this case. First, there have been similar problems with CFPARAM creating complex objects in the past. Second, and perhaps more importantly, there's significantly more overhead in checking for the existence of each of these objects in the Application scope before creating them, compared to checking for the existence of just one (or, even better, avoiding the need to check for any by placing the creation code in your onApplicationStart method).

Re: CFPARAM doesn't work as expected
It sounds to me like if the objects are being _assigned_ on each request
that it may be a bug... but make sure you check your application timeout
in your Application.cfc or CFApplication tag (whichever you're using) to
make sure you didn't accidentally assign it a really short timeout of
say a couple seconds that may be causing the application to timeout
between requests.
However... even if the value already exists in the application and the
cfparam tag behaves correctly, I would say this is probably not the way
you want to create your component objects. It would probably be a lot
better to use the onApplicationStart method of your Application.cfc or
optionally if you don't have one, to use
cfif isdefined(application.objects.cms)
cfset application... /
yadda...
/cfif
The reason for this may not be immediately obvious from looking at the
tags. The cfparam tag receives all its input _before_ it assigns
anything, so for example, if you were to say:
cfparam name=form.x default=#variables.x# /
This line will error out if variables.x is undefined, even if form.x
*is* defined. Why? Well, because it doesn't do anything with the input
until it has all the input, so it's looking for the default value before
it checks to see if there's an existing definition. Had I written the
engine I might have written it differently, but... I digress...
The long and the short of it is that if you use cfparam and put a
CreateObject() call in the default attribute, it's going to create one
every time the param tag executes it, whether it's used of not. So even
if it were retaining your application variables the way you wanted them
to, the server would still be doing a bunch of extra, unnecessary work,
creating new ones on each request.
Now there is an alternative that you may or may not like that allows you
to do basically what you were hoping for and at the same time prevent
the server from creating a whole bunch of components it's not going to
use:
cfcomponent displayname=appObjects
cffunction name=init access=public output=false
cfinvoke component=security returnvariable=this.security
method=init authorization=public
language=#Left(CGI.HTTP_ACCEPT_LANGUAGE,2)# /
cfset this.util = CreateObject(component,util) /
cfinvoke component=db returnvariable=this.db method=init
dsn=irama maxStringLength=25 /
cfset this.cms = CreateObject(component,cms).init() /
cfreturn this /
/cffunction
/cfcomponent
cfset application.objects = iif(
structKeyExists(application,objects),
application.objects,
CreateObject('component','components.appObjects').init()) /
The iif() function unlike the cfparam tag accepts strings as input
instead of the result variables and then determines which one to
evaluate once it's received it's input. So in this case, if
application.objects exists, then the string containing the CreateObject()
code isn't evaluated and it doesn't create that extra object that's
created by the cfparam tag.
Or you could just:
cfif not StructKeyExists(application,objects)
cfinvoke component=components.appObjects
method=init returnvariable=application.objects /
/cfif
Which is probably what I would do. Heck I might even wrap a named cflock
around that cfif statement just in case because iirc the server doesn't
single-thread the application start.

Re: CF Image question...
Right now I can do it 2 different ways.. one is to upload each one separately or I can ftp into the site and just upload the images then in the admin I can choose to upload one or run scripts if I have already uploaded them. If I have ftp'd them then it does run them 25 at a time, it starts with cfdirectory loop grabs the next images enters the info in db then makes the larger image and puts into into the large folder, then the thumnail and put it into the thumbs folder then moved that original image to a saved folder. I don't delete them at that point because I need to keep the original ones for downloading but the girl whos site is is then goes in and picks out the ones she wants and the rest get deleted and then the good ones zipped up and then the originals are deleted to save space. So to answer your ?.. it could but I guess it is just as easy to watermark them b4 hand. I run them through iwatermark and takes about 15 seconds to do 200 images but there are other sites where they may add a few pix a week where that would work.
