Tech and Tags
What's new in the Tag Gallery
- cf_img
- This custom tag presents a clean impression of any page comprising many graphical images by illuminating unsightly placeholders.
- ServiceMinder
- ServiceMinder allows you to view active services as well as start or stop any service.
- CF_PathIndex version 2.0
- CF_Pathindex version 2.0 is an update of the original cf_pathindex tag that I wrote a couple of years ago. Many people have expressed an interest in particular functionality that was not included in the original code, so here it is. The tag allows you to create a Verity index of a tree of documents on your server, but to exclude subdirectories in the tree by name. This function can be very useful if you use FrontPage extensions, for instance. Documentation is included in the tag itself.
- XMLvar
- XML Variable Identification Tag - For those who want simple XML interpretation. This tag can be used to interpret an XML string received by passing the variable name you are looking for. The tag will return the variable value as well as other valuable information.
- cf_generateobjectmodel
- cf_generateobjectmodel grabs property and method information from user-defined types and outputs them to a page in table-format. This is useful when you need to produce a report on your object model.
- Aversion.com E-Mail List Manager
- The Aversion.com E-Mail List Manager helps to automate your email distribution lists. It can be used to set up mailing lists for news or anything else on your site. The program comes with a fully functional administration screen that allows you to add, delete and modify addresses. You can also send emails directly from the administrator, and view archived emails. The system also comes with an Automated Email Tool, which will automatically process the email in your email list address inbox. This tool allows users to automatically subscribe and unsubscribe, and it will also remove any emails addresses that bounce.
- CF_Authenticate
- This ColdFusion custom tag protects directories and/or individual templates from public access.
- CF_RECYCLE_FORM
- This tag allows you to pull data out of any database table, and will let you populate a form if there are results. Perfect for Fusebox applications.
- MachineState
- CF_MachineState determines the current state of the machine that the code is running on. The valid replies to retState are "On" and "Off". If the state of the machine is "On" then retTimeToChange is blank, as the time when the machine will be on may not be determined by the OS. If the state of the machine is "Off" then retTimeToChange is equal to the time determined by the GetTickCount that tells when the server will turn on, or the state of the machine will change. This may be used to determine when the machine is available.
- CF_SourceBrowser
- A versatile utility for viewing and analyzing ColdFusion source files/directories. Integrates a source viewer with a 'FusionDocs' standard documentation parser/viewer, and eight separate software 'metrics'. An invaluable tool during all phases of the software development cycle.
- CF_SoftwareMetrics
- Returns eight separate "metrics" of a given ColdFusion template. These measure different aspects of logic and style, to give valuable information regarding reliability and maintainability. High 'risk' values may be a sign that the code needs to broken into smaller units, or at least that more extensive comments/indentation are needed. Based on Tom McCabe and Arthur Watson's "Structured Testing: A Testing Methodology Using the Cyclomatic Complexity Metric," 1996. Interpreted for CF by Lee Borkman.
- cf_multiplelistintersection
- cf_multiplelistintersection takes in an array of lists, and returns the intersection of all the lists.
- InflationCalculator
- This tag will take an initial year and dollar amount and give you a corresponding value, adjusted for inflation, in a second year. Data allows for dates from 1913 to 1999.
- Email Made Simple 2.0
- This new version of Email Made Simple handles all basic mail functions (send, receive, reply, delete), along with some new functions (send AND receive attachments, custom addressbook). Easy-to-use interface helps add to its functionality. Low price for what it offers!
- CF_MailMonger
- Calculates US Postal Service Priority Mail shipping rates. Since the rate tables are on your own website, there is no reliance on anyone else to produce your rates. Includes an admin utility so you can modify rates online.
- FreeData_USTrademarks
- This ColdFusion 4+ CFML custom tag uses CFHTTP to perform a keyword search on the Trademark Text and Image database of the US Patent and Trademark Office and return the results as a ColdFusion data structure.
- FreeData_EDGAR
- This ColdFusion CFML custom tag uses CFHTTP to retrieve a list of SEC filings from the EDGAR database. This tag can be used to create a custom EDGAR query for a corporate relations site, or to offer a free form search on a financial services site.
- FreeData_NWS
- This ColdFusion 4.1+ CFML custom tag uses CFHTTP to retrieve hourly weather reports from the National Weather Service's Interactive Weather Information Network.
- DP_PCQuote
- This ColdFusion 3.1+ CFML custom tag uses CFHTTP to retrieve price and fundamental packages from the PC Quote CGI service.
- DP_AlphaWords
- This ColdFusion 4.x CFML custom tag provides a simple way to ensure proper interpertation of such data as random passwords. It helps to eliminate confusion between "1" (One) and "l" (Lowercase L) and "0" (Zero) and "O" (Uppercase O). The tag takes a string and presents one of five standard "alpha word" encoding sequences. For example the tag might take the string "ABC" and return the standard NATO encoding of "Alpha Bravo Charlie". It can also present more detailed information to enforce case.
- CF_FormValidate
- CF_FormValidate is a simple validation tool that captures invalid characters submitted through forms. This tag is one line of defense against "Cross-Site Scripting" hacks.
- PlasmaFusion
- PlasmaFusion is a structured development environment and secure web application hosting platform for Allaire ColdFusion. The techniques employed by PlasmaFusion improve application flow and encourage reutilization, segregation and the maintainability of source code.
- Lotto Number Generator
- Lottery number generator. You specify the highest number that can be drawn and the game type. You can specify Pick 3, Pick 4, Pick 5, Pick 6 (Lotto) or PowerBall games.
- _Text to URL
- Turns plain text into URLs, or removes URLs from text and leaves as plain text.
- CF_UPSRateMonger
- Calculates UPS® rates using the 2000 rates downloaded from ups.com. Since all rate tables are on your site, no reliance on the UPS® web site or CFHTTP calls are necessary. The present version supports shipping (weights up to 150 lbs) in all 50 U.S. states and Canada (At present only Canada Standard shipping service is supported to Canadian destinations), and includes the fuel surcharge effective 8/7/2000. Future revisions may include UPS® ''accessorial'' options given sufficient interest, but this system provides enough functionality for most common needs.
- CF_DHTMLQUERY
- CF_DHTMLQUERY generates a table (like CF_DUMPQUERY) but each column is client-side resortable (using dhtml) if they are using IE4+. Otherwise, a normal table is generated.
- _EMail Pager
- This file checks remote emails, then forwards the messages to any other address (like a cellphone or pager). Handy for being notified of new messages to dumb servers (like at my work) that cannot notify you when new messages arrive, effectively freeing you up from having to check your emails all day long just to discover you have none.

Dispelling the Confusion: ColdFusion Enterprise vs. ColdFusion Professional
Luke Kearney (kearneyl@tky.ewc.co.jp) posed the following question on CF Community: What is the difference between ColdFusion Professional Server and ColdFusion Enterprise Server? Here are some of the responses:
- ClusterCATS is included with ColdFusion Enterprise, and not with ColdFusion Professional. (Camdon Spiller (cspiller@sunbeltusa.com))
- The Enterprise version includes the native database drivers, whereas the Professional version doesn't. This is not an issue with SQL Server, which uses ODBC/OLEDB. (Adrian Cooper (adrian@cooper.net))
- Bruce Kibbey (KibbeyBA@navair.navy.mil) sent this URL to the list (thank you, Bruce) for the full comparison between CF Enterprise and CF Pro: http://www.allaire.com/handlers/index.cfm?ID=13570&Method=Full&Title=Edition %20Comparison%20Matrix&Cache=False

User Interface Resources
Andy Edmonds of Figleaf has forwarded the following useful list of User Interface resource sites and recommendations, recently submitted to the Atlanta CFUG:"HCI is a occupational hobby of mine and I add HCI laden info to my search engine on a regular basis (1100 pages after 3 years of collecting). You can find it at http://psyberspace.net with commentary at /blogger/.
"Other good general resources are http://www.webword.com, http://www.useit.com (check the archives of the website spotlight), http://www.uidesign.net, http://www.asktog.com, and for look and feel analysis http://www.coolhomepages.com
"The general recommendation, unfortunately, is look at MS Word and http://www.aol.com, and do as they do. Consistency is priority number 1.
Regarding HTH and AE for application standards:
"For button naming (Save or Submit? Edit or Modify?), try http://psyberspace.net/web/searchresult.cfm?criteria=button+and+names
"For button placement (Save before Cancel or Cancel before Save?) and current trends (tabbed, explorer-like menus, etc.), try http://www.psyberspace.net/web/searchresult.cfm?criteri a=interface+and+trends

A Whole New Can of Worms
by James Moll(Taken from the ACFUG mailing list, with permission of the author. This was a response to Sean Harrison's challenge to clean up the formatting on our CF code):
<CFSOAPBOX action="step_on_up">
I would like to extend your challenge to include the regular 'ole html code, as well as CF code. I've been a "corporate", enterprise-oriented developer now since the mid '80s, coding in COBOL, REXX, C, VB, etc., and over the last couple years, HTML, Cold Fusion, and some ASP. In any programming language/IDE, you expect to run into different formatting preferences, as well as some expected laziness...but until I started doing web-related stuff, never in my varied development career have I ever witnessed such utter and total lack of any type of attempted code formatting discipline whatsoever! I don't mean to be a developer snob here, but I've just shrugged it off as being a by-product of the original nature and intent of html, and therefore its use and adoption by "designer" and "content supplier" types (read "non-programmers").
But enough already! By the very fact that we are using the ColdFusion application server, and that this is a ColdFusion users group list, we all here are now officially "application developers," not simply web page "designers". As a result of your newly christened title, there is, like many titles in the world, some implied responsibilities that are now expected of you as a "developer"....to wit,
- THOU SHALT FORMAT THY CODE TO FACILITATE READABILITY AND MAINTENANCE.
- THOU SHALT FORMAT AND INDENTETH NOT ONLY THY CF CODE, BUT ALSO THY HTML, AND THY JAVASCRIPT.
(ok, I don't really have time to parody a full set of 10 commandments, but I think you get the drift...)

Techniques
QuickTip: Installing CF Custom Tags Remotely
What if you wanted to install your CFX tags remotely and didn't have access to the CF Administrator?This question, posed by Sean Harrison on the ACFUG list, brought to light the following operation:
- Getting the .dll's to the right place is pretty trivial if CFFile and CFDirectory are enabled; You might use CFRegistry to create the required entries, and then it should be good to go. May possibly have to wait until after a machine reboots, if the CF administrator does anything exotic, but possibly not. (Sean Harrison)
- Just get the CF admin CFX reg page filled out to register the CFX, run RegMon on the cf server (http://www.sysinternals.com/regmon.htm) and hit APPLY. Regmon will capture the registry edits that CFadmin is making. You may have to stop all unnecessary background processes (antivirus etc.) so that regmon only captures the events that you need. I use this technique to troubleshoot and reverse-engineer/bit twiddle win32 apps. (Jim Cable)

Last Weeks Questions
- Name all the CFLOOP types and what they do.
- Index loop - Takes 2 numbers and loops from the first (FROM) to the second (TO). The steps and direction of the count between these two numbers can also be controled.
- Conditional Loops - Takes a conditional statment and as loon as it is true will run a loop. This look has no Index or counter so you must write in code to stop the loop. When an infinate loop occurs, this loop type is usually the culprit.
- Looping over a Query - Loops over a query in the same way a CFOUTPUT does, looping over every row in the query record set. During each iteration of the loop, the columns of the current row will be available for output. CFLOOP allows you to loop over tags that can not be used inside CFOUTPUT. A CFOUTPUT must still be used for the evaluation of variables.
- Looping over a List - Takes a list (with a default or defined delimiter) and loops over each item in the list. The Index attribute is loaded with the current list item on each loop iteration.
- Looping over a COM Collection or Structure - Loops over each item in a structure (ColdFusion) or a collection (returned from COM).
- Conditional Loops - Takes a conditional statment and as loon as it is true will run a loop. This look has no Index or counter so you must write in code to stop the loop. When an infinate loop occurs, this loop type is usually the culprit.
- Name all the Loop types in CFSCRIPT and what they do.
- for loop - Takes a number and loops until the conditional part of the loop is fales. The number can be added to in order to make it like an index CFLOOP. It cal also run as an infinate loop where there is no stop condition. This loop has many ways of being used.
- while loop - Loops while a condition is true. Same as conditional CFLOOP
- do-while loop - Same as a while loop, but the test to see if the loop stops is done at the end of the loop rather than the beginning.
- for-in loop - Loops over a structure.
- while loop - Loops while a condition is true. Same as conditional CFLOOP
- Can you loop over a query in CFSCRIPT and if so, how do you do it?
- Yes
- Assume a query named "queryone". We will loop over each row of the query and then loop over each column in the row.
<CFSCRIPT>
// write the column headers in bold
for(loop0=1; loop0 LTE Listlen(queryone.columnlist); loop0=loop0+1)
WriteOutput(' <b>'&listgetat(queryone.columnlist, loop0)&'</b> ');
//Add a new line after the headers
WriteOutPut('<br>');
//Loop over each record in the query
for(Loop1=1; Loop1 LTE queryone.recordcount; Loop1 = Loop1 + 1)
{
//Write out each column of the record
for(loop2=1; loop2 LTE Listlen(queryone.columnlist); loop2=loop2+1)
WriteOutput(Evaluate('queryone.'&listgetat(queryone.columnlist,loop2)&'[loop1]'));
// Add a new line after the record
WriteOutPut(' <br>');
}
</cfscript>

Microsoft IIS 5.0 Translate: f Source Disclosure Vulnerability
According to Security Focus, Microsoft IIS 5.0 has a dedicated scripting engine for advanced file types which handles requests for these file types, processes them accordingly, and then executes them on the server. It is possible to force the server to send back the source of known scriptable files to the client. The scripting engine will be able to locate the requested file, but will not recognize it as a file that needs to be processed and thus will send the file source to the client. Microsoft has issued a patch.Microsoft IIS 5.0 "Translate: f" Source Disclosure Vulnerability (Security Focus Alert)
