CFXML - save with cffile - dont' work
Hi every One,
I have some problem to save an CFMX XML doc on hard Disk
I download xmlxslt tutorial on Macromedia.
Everything is ok, but when I try to save on hard disk with CFFILE, the
file is correctly create but totally Empty... nothing
Code I used and result I obtained is bellow. If I execute file in
browser I have just : XML has been written to disk.
Is there an logical explanation ?
I turn on window 2000 SP3 - IIS - CFMX Sp1
I recently installed free webTrend extension from webtrend site, but
even I uninstall them it doesn't work
Please help me understand
Eric

ColdFusion for kids
Hi all, My little brother, who's 13, is just starting to learn HTML. I'm storing his personal site on my CF5 account. He wants his site to be cooler than anyone else's at school, so I was thinking of making him a simple CF tutorial - maybe using cfinclude to get a header on each page, displaying and formatting the current date and time, stuff like that. Before I do this all myself, does anyone know of anything similar online already? Or, any suggestions for what I could include? Thanks, Kay. - http://kay.smoljak.com ~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribeforumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Get the mailserver that powers this list at http://www.coolfusion.com
Re: ColdFusion for kids
Kay what a great idea! Don't know of any existing tutorials, though. Just some thoughts: Once he learns html well enough, CF shouldn't be too hard for him-- in fact, you may have trouble keeping up! The key, I think is being able to pique his interest. Do they have computer labs at the school he attends. As a challenge, you might have him try to duplicate some of the programs they use/write in the lab, on his web site-- likely, CF/HTML has more power and presentation capability then what they use in the lab (excluding word, excel, etc). If he has friends with email accounts, set up a mailbox for him on your site -- then have him develop a simple CF program to: 1) send mail 2) maintain an address book of his friends 3) receive mail This could evolve to his own little email client. At some early point, introduce him to a simple database, say for his email clients Ask him what he would like to have on his web site -- what interests his friends -- likely the data processing needs of a teenager are not too different than our own. Does he collect anything -- write a program to keep track of it! If he has access to a digital camera or scanner, then have him create a photo album/slideshow where CF and a simple db is used to store image metadata for search, display, etc. He could do the same thing for his audio. Not really CF, but he might like playing with SVG or Flash for some graphic animation effects. A really cool capability, for when his skills have improved, is for him to write a chat program that all his buddies can use (with secret passwords, etc).I think there several several offerings in the tag library that could be used as a starter. Then, have him write a tutorial to teach his friends, etc. Before long, you'll be asking him to answer questions about CF! I have a six-year-old grandaughter we are email pen pals -- the kids have no fear! Be sure and share the results with the rest of us!

Re: ColdFusion for kids
Some additional thoughts: Be sure to show him where/how to access CF online docs. In one of his first programs (actually a series of programs), have him create and manipulate a list of whatever interests him. It is important to use a list in application, not a textarea (where he can massage a single data entity) Point out to him that the list will disappear when his session ends. Then have him save the list to a file Next have him retrieve the file, display it in a select box Next have him add items to the end of the list Then add items to the middle of the list then delete an item then update an item in place After he is proficient with this, show him how to do this with a db rather than a flat file. So, now you have a 13-year-old who understands HTML, CFML, SQL-- watch out! Dick P.S.

RE: Lists vs. Arrays vs. Structures
I'm not sure what you are really trying to accomplish here. It is a well known fact that the data structure of choice to do a linear search against is a list. Any linear search is going to be O(N) plus whatever overhead each operation incurs and a list has the lowest overhead per operation. You only want to use arrays or maps (structs) when you require random access to the data. Arrays tend to be a good way of representing different types of trees, which generally are the best data structures to search for a value against. For example, balanced trees can generally offer O(log N) worst case. Finally, maps are generally meant to be when you are dealing with known keys. If you know the key, a map is O(1) for retrieving the value, which is always going to be better than any other data structure. However, if you attempt to search a map without knowing a key then you are really no better off than searching a list. See http://www.cs.fiu.edu/~weiss/ for more information on algorithms and data structures. Matt Liotta President CEO Montara Software, Inc. http://www.montarasoftware.com/ 888-408-0900 x901 -Original Message- From: Michael Dinowitz [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 04, 2002 12:06 AM To: CF-Talk Subject: Lists vs. Arrays vs. Structures I'm rewriting my CFMakeTree tag in order to make it tighter and work in CFMX better. One of the assumptions I had was that Lists would be problematic in comparison to Arrays or Structs. My first test was to find a value in one of these data collections. For Lists I used ListFindNoCase. For Arrays, I looped over the array to find the value and for Structs I used StructFindValue(). I ran each test in a 1000 iteration loop to see if anything showed up. On the whole, Arrays took the longest, which is to be expected as they had to loop (no native arrayfind function). Structures took less then 10% of the array time to search and lists took 1/3 of the struct time. The data set was 0-9a-z written out in full and the item searched for was the z. So the results are basically that lists are easier to search than either structures or arrays. As a side note, I tried using a query of queries and it was much, much slower. The second experiment was to loop over each data collection. In this, we see much different results. Arrays were fastest. Lists were anywhere from about as fast as an array to twice as slow. Structures tended to be on par with lists, but sometimes slower. On the whole, unless you see a need to, I'd stick with using lists in CFMX. I have heard of people who have seen some major slowdowns due to lists and I'd love to hear the specifics.

CF4K was Re: Macromedia listening? is RE: ColdFusion for kids
Mike Isn't Kay's idea really great? I didn't mean using trying to compete with word for producing clear, concise html -- who could do that :) Rather, schools teach word and excel for their data presentation and problem-solving capabilities, respectively. More importantly, the use of these tools is likely standalone. CF4K, would broaden the problem-solving and presentation capabilities and add the ability to interact with others over the web or a LAN. All the schools are wired for the internet, right ? -- I saw Bill and Al on TV, laying the cables. And we continue to pay taxes (phone bills) for this. So the Internet should available to all schools (but access may be restricted). I think that many high schools have LANs for their computer labs. These likely are used mainly by the instructors to broadcast the lesson to all the displays and to monitor or assist individual students. Your idea about DWMX is an excellent one. I think we could go a step further. Make available a Modified Trial version of CFMX especially for classrooms. One that they could install on a server (or the main computer on the LAN, that acts as such). Then schools could teach problem solving, development collaboration, web/network application development, etc -- without needing access to the Internet The components would be something like: HTML as the basic presentation layer Flash, etc, for the rich/extended presentation layer CFML for the problem solving layer SQL for the data management layer The SQL piece is already available (open source, or from several vendors) For example, Sybase_ASE has an free, easy to install, full-featured database (very similar to SQL-Server) that allows 25 (I think) concurrent connections-- even that's not a problem as CFMX pools connections. Getting back to Kay's original request, what's missing is some tutorials oriented to kids -- there are companies that specialize in doing that for any topic -- but I suspect that many of the members of this list have the talents necessary to develop CF4K material. It must be a slow day -- is some holiday approaching? This is such a great idea, that I am surprised by the few responses. Maybe, everyone sees the potential and are busy presenting the case for this or that to those who can make it happen -- that's what I did!

CF4K... What about tying in Flash4K as well?

I didn't mean using trying to compete with word for producing clear, concise html -- who could do that :) Rather, schools teach word and excel for their data presentation and problem-solving capabilities, respectively. More importantly, the use of these tools is likely standalone. CF4K, would broaden the problem-solving and presentation capabilities and add the ability to interact with others over the web or a LAN. All the schools are wired for the internet, right ? -- I saw Bill and Al on TV, laying the cables. And we continue to pay taxes (phone bills) for this. So the Internet should available to all schools (but access may be restricted). I think that many high schools have LANs for their computer labs. These likely are used mainly by the instructors to broadcast the lesson to all the displays and to monitor or assist individual students. Your idea about DWMX is an excellent one. I think we could go a step further. Make available a Modified Trial version of CFMX especially for classrooms. One that they could install on a server (or the main computer on the LAN, that acts as such). Then schools could teach problem solving, development collaboration, web/network application development, etc -- without needing access to the Internet The components would be something like: HTML as the basic presentation layer Flash, etc, for the rich/extended presentation layer CFML for the problem solving layer SQL for the data management layer The SQL piece is already available (open source, or from several vendors) For example, Sybase_ASE has an free, easy to install, full-featured database (very similar to SQL-Server) that allows 25 (I think) concurrent connections-- even that's not a problem as CFMX pools connections. Getting back to Kay's original request, what's missing is some tutorials oriented to kids -- there are companies that specialize in doing that for any topic -- but I suspect that many of the members of this list have the talents necessary to develop CF4K material. It must be a slow day -- is some holiday approaching? This is such a great idea, that I am surprised by the few responses. Maybe, everyone sees the potential and are busy presenting the case for this or that to those who can make it happen -- that's what I did!

Actually the best starting place for the youngsters is to use pre-built templates, available everywhere for free, to use Web builder apps provided by the host. They always have the option to view and tweak the HTML code that underlies the site. More advanced languages, such as CF, PHP, XML, JavaScript, Perl, various flavors of SQL, etc. are for the more advanced students, and usually the ones that have a proclivity for structured programming languages.

Re: ColdFusion for kids
Wow... thanks to everyone for all the responses! Here's what I think I'm going to do. I'll create a couple of basic tutorials, and test 'em on my brother. Then I'll put them online on my site, so if anyone else wants to mould the mini-nerds in their lives, there's somewhere to start. I've taken all your ideas on board. Jochem, I see your point. But these kids are already doing some computing in school, and I think they are better off learning something they can build on in the future than how to use Word (it was Microsoft Works when I was in high school, but same deal). In my brother's case, creating his personal site - that was last weekend's project - also involved checking his spelling, grammar, and thinking out his message so it was clear and made sense. I'm emphasising quality control at every step. He's using DWMX (as he's using my computer), so we're looking at the html source a little too. He's interested in creating web sites, so I want to encourage him to try new, more challenging projects. Interesting anecdote: when he first took his school project html site and started editing it for real, each page had a different horrific tiling background. My Dad and I tried not to say anything, not wanting to dampen his enthusiasm. But a week later he had removed all the hideous backgrounds and put a consistent colour scheme on each page. Kids really do learn by osmosis. I bought him a book called html with css and xhtml for Christmas - we'll get rid of those tables yet :) Macromedia have a very small presence in Australia. If anything, I think their educational focus should be getting CF into universities first, which is starting to happen. But for kids with an interest, who want to be ahead of their peers, I think CF is a great stepping stone.

RE: ColdFusion for kids

Before I do this all myself, does anyone know of anything similar online already? Or, any suggestions for what I could include? At one point, Macromedia (or Allaire, I forget which) offered a tutorial CD, called SkillBuilding or something like that. You might look for that - it was around $75 or so.

RE: ColdFusion for kids
P.S. There is a member of this list who was/is a teenage prodigy with CF (and quite a few other web technologies) -- Dave, if you see this, you could provide some real-life experience for input! I'm not sure whether you're referring to me, since there are plenty of Daves, so forgive me if I'm presuming too much. If you are referring to me, I unfortunately will have to disappoint you, since I was never a teenage prodigy with CF or anything else, although I was considered pretty competent with small arms in my late teens. I can comment on learning programming informally, though. I didn't come from a CS background, but learned programming the hard way, by trial-and-error, basically. Being self-taught sounds nice, but if you think about it, it's kind of silly - if you're self-taught, your teacher is by definition incompetent! And, that sums it up pretty well - by not learning programming in a formal setting, I made it a lot harder than it had to be. I think that this is true for a lot of people who got into programming during the web boom, actually - the lack of formal training is often very apparent. Kids will learn to program the Internet -- just because it's there! Why leave them to their own devices and some of the more obscure languages -- to helter-skelter mix format layout and content. Rather, teach them to do it right (better) with superior tools. Are you saying that while the CFMX approach is good enough for you and I to use, it is not good enough for our kids? What do you propose instead? I hate to be a wet blanket, but I'm not a big fan of teaching CF programming to kids, for several reasons. First, I'm not sure that we should be teaching programming to kids generally; on the list of things that everyone should learn, I think it's pretty low. There's a difference between learning basic computer skills (which, sadly, are necessary for almost everyone nowadays) and learning how to program. I think it's a sad commentary on the state of the computer industry that people have to spend so much time learning basic computer skills, actually - these things are supposed to be easy to use, but of course they aren't, really. I'd much rather see every student have a firmer grasp on the three Rs than have them all able to churn out web applications. I'd rather see civics classes again, actually. I just don't think programming is all that important, I guess. Second, for those students who want to learn programming, I think it's more important to focus on core programming concepts than it is to teach the specifics of CFMX. I'd rather see them learn programming using a lower-level language than CFML, and a more general-purpose language, too. I think Java and Python would be better languages for learning how to program. Finally, for teaching purposes, you don't want to make things too easy - for example, if you wanted to teach someone about HTML, Notepad would be a better tool (I think) than Dreamweaver MX. I see this a lot, actually, now that Dreamweaver is used in the Macromedia courses. The Fast Track To ColdFusion class is easier for students, because they don't have to know any HTML to get through it, but the students don't actually know how to generate a dynamic select box, say, because in Dreamweaver you do it by clicking on a button or two, rather than by typing in the necessary HTML and CFML. So, yes, CFMX is good enough for us to use, but not good enough for our kids. Personally, I'd be very distraught if my kids ended up being CF programmers. Shouldn't we want our kids to be better off than we are? (I don't have any kids, so this is purely hypothetical for me. If I did, I'd be pushing them toward law school instead of programming.) So, now you have a 13-year-old who understands HTML, CFML, SQL-- watch out! That's all well and good - if he's going to start working today as a consultant. In the long run, again, I think he'd be better served by learning general programming theory rather than the specifics of languages that may well be obsolete by the time he's ready to work in the field.

RE: CFSET in CFMX
It's really interesting - to me - to see such attention to such 'small' language details in terms of performance. ColdFusion is the only language I've ever worked in where such small details made such big difference in speed... and now it seems it is only historical (which is code: CFML now behaves more like other languages). In my experience, which may run contrary to others', these small language details didn't generally make much difference in CF 5 or previous versions, actually. For some reason, though, CF programmers have tended to focus on them to a degree way out of proportion to their actual impact on the average web application. I'm not sure why this is; I think it might have to do with the degree of ambiguity and looseness in CFML. I've worked with quite a few CF applications, though, and I haven't yet encountered a situation where these sorts of things were the performance bottlenecks within the application. So, when I see these sorts of things, they bring to mind debates about how many angels can dance on the head of a pin. Meanwhile, I've seen far too many CF developers neglect the very foundations of adequate web application performance - caching, database optimization, server tuning, and did I mention caching?

Re: Lists vs. Arrays vs. Structures
I think your missing the point of what a list is in ColdFusion in relationship to what an array or structure is. A list is simply a string that will have to be parsed by CF to be seen as a collection of data. After its been parsed it can then be searched. That parsing, especially when done in Java is what the true question is. Will a structure, which already has the individual items separated into storage areas operate faster than a string which has to do more work? I'd expect the structure to be faster, but its not. I think that a new array search function might be in order here. Something to look through an array for a value and return its index. I'm not sure what you are really trying to accomplish here. It is a well known fact that the data structure of choice to do a linear search against is a list. Any linear search is going to be O(N) plus whatever overhead each operation incurs and a list has the lowest overhead per operation. You only want to use arrays or maps (structs) when you require random access to the data. Arrays tend to be a good way of representing different types of trees, which generally are the best data structures to search for a value against. For example, balanced trees can generally offer O(log N) worst case. Finally, maps are generally meant to be when you are dealing with known keys. If you know the key, a map is O(1) for retrieving the value, which is always going to be better than any other data structure. However, if you attempt to search a map without knowing a key then you are really no better off than searching a list. See http://www.cs.fiu.edu/~weiss/ for more information on algorithms and data structures.

One of the assumptions I had was that Lists would be problematic in comparison to Arrays or Structs. My first test was to find a value in one of these data collections. For Lists I used ListFindNoCase. For Arrays, I looped over the array to find the value and for Structs I used StructFindValue(). I ran each test in a 1000 iteration loop to see if anything showed up. On the whole, Arrays took the longest, which is to be expected as they had to loop (no native arrayfind function). Structures took less then 10% of the array time to search and lists took 1/3 of the struct time. The data set was 0-9a-z written out in full and the item searched for was the z. So the results are basically that lists are easier to search than either structures or arrays. As a side note, I tried using a query of queries and it was much, much slower. The second experiment was to loop over each data collection. In this, we see much different results. Arrays were fastest. Lists were anywhere from about as fast as an array to twice as slow. Structures tended to be on par with lists, but sometimes slower. On the whole, unless you see a need to, I'd stick with using lists in CFMX. I have heard of people who have seen some major slowdowns due to lists and I'd love to hear the specifics.

This led me to do some searching for Logo and turtle graphics (2nd grade for me) and I found this, and it actually pertains to the original thread (kind of) http://c2.com/cgi/wiki?WhatSortOfComputationWouldInterestJuniorSchoolCh ildren This is an off-shoot of an article talking about Logo in general.
