Re: The Len() function...Splitting Hairs?
> CF is beyond loosely typed. It's basically typeless. actually, CF types the variables when the variables are being used. allaire terms this "lazy evaluation". for example. if you ever try using a string in a mathematical equation you will get an error message. when you create a variable, cf doesn't really assign a type to it, but when it evaulates the variables it checks the type. -emily -- Archives: http://www.eGroups.com/list/cf-talk To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=lists&body=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body.
Re: Captupturing Form Elements
if you're using 4.5, form variables are automatically in a structure (named FORM) that always exists - it's just empty if there is no form submission. what i would suggest is on your action page, just do a StructKeyList(FORM) which will give you a list of all the keys (the formfield names). from that you will be able to get the form values. this is the same idea as brian set out below, but it works with a structure instead of a list which i would think would work more quickly. -emily Brian Peddle wrote: > > You can loop over all the fieldnames submitted: > > > > Put whatever processing on the fieldnames you need here > > > -- Original Message -- > From: "Lee Moore" <[EMAIL PROTECTED]> > Reply-To: [EMAIL PROTECTED] > Date: Thu, 6 Apr 2000 09:36:42 -0400 > > >Hello all. > I have a work page that may recieve form submission from several different > pages.

RE: DISPLAY QUESTION
> > > > > >#newWords# hey sean...that's a nice way of handling it! my mind is so linear sometimes that i tend to not think about looping unless it's obvious like when i'm working with arrays and structures. since i'm always looking at optimizing code, i started to play around with both methods to get those 6 words. i found that it doesn't matter how long your text is, if you only want the first 6 words, then both methods work equally fast. (i went to cnn.com and filched a long article) but if you're looking for more than 6 words, the overhead for the looping becomes quickly apparent. for instance, at 200 words, the looping took 200 ms while the other way took 70ms. however, the looping seems to be more accurate. when i specify 400, for instance, the looping returns 399 words while the other way returns just 370. i'm not sure why that is (btw, i just took the resultant output and did a word count on them in word) but you should be aware of it. ...just thought it was interesting -emily -- Archives: http://www.eGroups.com/list/cf-talk To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=lists&body=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body.

you might want to try to do the call to CFHTTP but have a CFCACHE tag at the top of the page.

Re: CF Classes
oh, one more thing...in the ftcf course you build an application from the ground up, so you get a good sense of how to build an entire application - adding in a simple security level as well. but in the acfd, most of the applications are already built and you just add the higher functionality to it (and a lot of the application uses session/application variables). so, i've found that people with less experience with cf tend to get confused in this class because it's harder for them to figure out what the application is doing since they didn't build the whole thing themselves. ok, enough ;) -emily At 11:42 PM 4/18/2000 -0600, you wrote: >>Would you recommend a relative newbie like myself take the advanced one?

memory variables & cflock
btw, for those of you who will/are using server, application, or session variables, you should also be locking those variables using CFLOCK. more information on that can be found in this knowledge base artlcle: http://www.allaire.com/Handlers/index.cfm?ID=14165&Method=Full this article also has a link to a migration tool that will upgrade your code from 4.01 to 4.5 (locking is implemented differently in 4.5). -emily -- Archives: http://www.eGroups.com/list/cf-talk To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=lists&body=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body.

jennifer - if you don't scope attribute variables, they won't be found at all. you must scope those variables. hth! -emily At 03:13 PM 4/19/2000 -0500, you wrote: >I don't understand if you are saying that I'm wrong or if you are saying >that it won't find the variable if you don't put the attribute scope. >Either is totally possible, so please let me know, just for the record. > >At 01:29 PM 4/19/00 -0500, you wrote: >>The server does not implicitly look in the attribute scope.

RE: What's the difference?

Re: simple createODBCdate question
in this case, the pound signs really aren't even necessary because you're
already in a cfset statement. i think the recommendation is to not use them
inside of cf tags because you're "over-coding". try:

helps.

Re: the definitive summary to variable scopes - correct?
i believe that Request variables also belong in that upper list. in answer to your question about a difference in scoping vs. not scoping in the lower list, you can choose to use the prefixes or not. some people purposely do not scope their variables to make their templates more flexible (allows them to use the same template to either accept info from, let's say, both url and form variables). but the recommendation from allaire is to scope the variable because: 1. it avoid confusion for the developer (sometimes you may have variables of the same name from different scopes on the same page) 2. if avoids confusion for the cf app server, too (if you have to variables of the same name but different scopes on the same page and you don't scope the variables, then it process the variables in the "scanned order" you have listed below - whichever one it hits first is the one that is used) 3. supposedly, there is a performance gain if you scope the variables 'cause cf doesn't then have to scan for you. -emily >variable scope required: > 1) Server > 2) Application > 3) Session > 4) Attributes > 5) Caller >variable scope not required, scanned in the following order: > 1) local (i.e. Variables) > 2) CGI > 3) File (???) > 4) URL > 5) Form > 6) Cookie > 7) Client >- is there any difference in using Variables.x and not using it? >- what are File variables? >--- --- >Archives: http://www.eGroups.com/list/cf-talk >To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=lists&body=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body. > -- Archives: http://www.eGroups.com/list/cf-talk To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=lists&body=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body.
Re: quotation marks -- definitive answer?
>a) >b) #---# not required >other than I dont believe there are any differences. actually, if you're assigning a variable to an attribute in a custom tag (even with cfmodule), you will need the pound signs because the custom tag, unlike the other cf tags, don't assume that something is a variable. for instance in your example "b" above, if you don't have the # signs, the custom tag will be passed an attribute called myattribute with a value of "foobar" - but if you put the pound signs in, then the attribute will actually get the evaluated value for the variable foobar because then it knows its a variable. but, of the other cf tags, the # signs are not required. >a) >b) >a) >b) for just straight values to an attribute, the double quotes are only really required if the value has a space in it...otherwise, they aren't required. but i believe that the "best practice" usually is to put double quotes around your values. -emily -- Archives: http://www.eGroups.com/list/cf-talk To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=lists&body=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body.
Re: Application.cfm Question...
in your subdirectory application.cfm did you name the application again? ? since application variables belong to specific applications, i think you need to specifically declare that it's stil part of the same application. -emily At 03:41 PM 4/25/2000 -0500, you wrote: >Are application.(variablename) variables truly persistent.
