Re: REGEX hell
I agree that the * (0 or more) should be avoided unless needed but in this case I felt it was. There may or may not be a space. There may be more than one space. There may be a space character being seen as a space (like a tab). Because we don't know if a space will actually exist, the * is needed. The +? (1 or more but as few as needed) assumes that at least one space exists. As a rule I don't over-worry about using * when it's used with a \s (space) unless I really have to.

RE: REGEX hell
For future reference you should avoid using * where possible as it can easily lead to overmatching. Even using + would be better although both + and * alone are greedy matches. An even better solution would be to use a lazy match like so: \)\s+?\) The ? following the + tells the regex engine to match as little as possible. andy -Original Message- From: Rick Colman [mailto:rcol...@cox.net] Sent: Monday, November 22, 2010 9:59 PM To: cf-talk Subject: Re: REGEX hell This worked!!

Re: REGEX hell
no need to escape the space char with a slash. are you sure it is only 1 space, and are you sure it is a space char (chr(32))? If so, remove the slash in front of the space, and it should work. also, pet peeve, no need for the ## around the function. Works either way, though, so ignore if you prefer.

Re: Detect users based on country???
Use a public geo-location service: http://ipinfodb.com/ip_query.php?ip=#cgi.REMOTE_ADDR#"; result="response" /> Then use the response XML tree to extract the country or zip: #price# I wouldn't actually do it in this order because of the lag in http posts. I've had good luck with this method but it isn't perfect because web services can go down and then your checking system breaks. If the location service isn't working, then don't allow anyone to use the module you've built with the integrated geo-location service.

ColdFusion & LCDS Session Management
Has anyone on the list had any experience implementing session management for LiveCycle Data Services into ColdFusion 9? I am building an app using CF, Flex & LCDS and am trying to find a way to call a few clean up methods on the CF side when a user disconnects. Unfortunately, I haven't found much online other than a few unanswered questions on the same topic. I am pretty new to CF & LCDS, but it seems it would need to use the FlexSession Java class (something like this... http://sujitreddyg.wordpress.com/2008/05/16/session-data-management-in-flex-remoting/), but I have no idea how to use java event listeners within CF. Thanks for any help ahead of time.

CF8 cfcookie vs cfheader set-cookie
I was updating our application to support httponly cookies and came across what seems like a ColdFusion quirk. I had to update a bunch of pages where we used to set cookies using cfcookie tag, so I went ahead and created a custom tag that all templates can use to set a cookie. Since CF8's cfcookie does not support httponly flag (CF9 does), I used cfheader to set the cookie in the custom tag and here is what I found. When you use the cfcookie tag to set the cookie, coldfusion populates the cookie struct right away. But if you use cfheader instead to set the cookie, I believe coldfusion does not populate the cookie struct until the next request. I spent a couple of days chasing this issue and trying workarounds for it without success. So, the only thing left to do was to do a relocate to the same template the first time the cookie is set using cfheader so that coldfusion populates the cookie struct. (Manipulating the cookie struct is out of the question since that messes up the cookies.) Here is a test case to prove this: On the first page load, the cfdump will only have the cfcookietest cookie in the cookie struct. Only on the second request will the cfheadertest cookie be present in the cookie struct. Hope this helps others who are facing the same issue. Please reply/comment if there is a better way to handle this.

Use cftry/cfcatch around your calls to
rootObject.Get_ObjectName().Get_Value() instead of trying to treat the
values within your object as if they were structures, etc.

Using isDefined/StructKeyExists against a ,Net com object
I'm doing some .Net integration and the values of the .Net object returned need
to be inspected and then displayed if they are defined
I've found that the conversion process brings everything back as
rootObject.Get_ObjectName().Get_Value() which blows up if the object is empty
throwing an undefined error - However if I try and use
isDefined("rootObject.Get_ObjectName") or
StructKeyExists(rootObject,"Get_ObjectName) - it just doesn't work - If I add
in the () at the end - it blows up Coldfusion
I can't just display everything because there may be elements that are empty -
Has anyone else had this problem & have a solution?

RE: CFDocument and Images
I believe CF actually uses iTtext (http://itextpdf.com/), you could try manipulating this directly and see if you have the same issue, if so then perhaps updating iText may solve the problem.

CFDocument and Images
Hi, How does CFDocument, serving a PDF, go about actually getting images? We have a fairly complex report that returns a PDF with a fair amount of CFCharts within it. We were initially seeing a lot of timeouts creating the image, then moving the site to a multi-instance CF caused more mahem. So we changed the code to first save the image to a temporary location and generate the PDF from that. All was going well, we thought. There are two questions in a report (not all) where the image displayed for the answer is wrong. Running the same report outside of the CFDocument producs the correct output. In both cases, the correct images are written to disk. The image shown in these two cases are another image also included in the report. First we thought it was a CF9 v CF901 problem as the Dev server is 901 but the live server is 9. However I've managed to reproduce the problem on CF901 with two images and a very simple table. The image files themselves are different, I've tried getting MD5s of the images and these differ. When run, there are two images embedded in the document, but both are of the first image encountered. Changing the order of the images changes the output. In attempting to debug this, we have tried using UUIDs to ensure the filenames are unique, adding an ?rnd=#CreateUUID()# to attempt to stop caching, all have failed. The only way I've managed to get the images to work properly (as I thought it was an HTML issue to start with) is to watermark the images like: This makes the image ugly, but the correct one. Strangley, if I change the SetDrawingColor to white, as the text appears over a white background, then the same problem persists... Has anyone got any ideas, as I'm now stumped...
