CFMeetup: CFPOI Project: CFSPREADSHEET (& more) for Any CFML Engine (View video , Show Description )ColdFusion 9 has introduced CFSPREADSHEET into the lexicon of CFML, but what if you're going to be on an earlier version of ColdFusion for a while, or what if you you use BlueDragon, Open BlueDragon, or Railo?
Does this mean CFSPREADSHEET is out of reach for you?
Absolutely not, thanks to the CFPOI project. CFSPREADSHEET and some of the other document functionality in ColdFusion 9 is built on top of Apache POI, which is an open source project that provides a Java API to
interact with Microsoft Office and OpenOffice.org documents.
The goal of the CFPOI project is to allow CFML developers on all engines access to CFSPREADSHEET and (eventually) much more through CFCs, UDFs, and custom tags that leverage the Apache POI libraries. Spreadsheet functionality is the first piece of the CFPOI project that has been released, and while it mirrors ColdFusion 9 syntax with its UDFs and custom tags, it also allows for more direct interaction with the POI libraries if desired.
Come learn how you can add CFSPREADSHEET to any CFML engine, and how easy it can be to leverage any open source Java project in your CFML code.

CFMeetup: CFUNITED Preview: Using Apache Derby (View video , Show Description )Come see a preview (about 20-30 minutes) of one of my CFUnited sessions, this one on Apache Derby. No, it's not "new in CF9", but many have missed or dismissed it. In this session, you will learn about the Apache Derby database included in ColdFusion 8. A full-featured database with a ten-year heritage, Apache Derby is fully transactional, easy to use, and standards based and has the advanced features you'd expect in any quality DBMS. Yet it's small, at only 2MB. You'll find out how to use Apache Derby within ColdFusion, as well as about tools that work with it and where to learn more. Again, this is just a preview, but for many it will be more than they've ever heard about the Derby DBMS embedded in CF8. I'm sure some will have preconceived notions about the tool. Come share your thoughts. I hope to dispel a few myths along the way.

CFMeetup: Getting Started with Multiple Instances in CF (View video , Show Description )Have you wondered about using or trying out the "multiple instance" feature of CF (technically the "multiserver" installation option). Available in its current form since CF 7, many developers and shops still have not adopted it, perhaps because they don't understand its benefits, or maybe they tried it and got confused about the options during installation/configuration. Or maybe they assume it's only about creating clusters/load balancing and/or replication: it's not and can be valuable for many other reasons.
In this talk, veteran CF troubleshooter Charlie Arehart will introduce the topic, presuming you have no prior experience with it. (Note that while it's a feature of CF Enterprise, you can also use it with the free Developer edition, and he'll explain why you may want to.)
What we will (and will not) cover:
We'll address things from the ground up, starting with what the feature is, how it's evolved, and why you should use it in development and/or production. Charlie will demonstrate an installation from scratch, talking about the various choices presented, and proceeding to add another instance and how to demonstrate successful setup. He'll also show connecting the new instance(s) to an external web server and share tips about that.
Along the way Charlie will address such other practical concerns as how to share admin settings among the instances, whether and how to share jvm.config settings, how to find the various logs for each instance, why to be careful about scheduled tasks, how you can monitor the instances, and more. He'll also offer some recommendations that could vary depending on your setup, such why you might want to use the cfusion instance only for creating instances, when/why you may be able to stop and disable the cfusion and admin instances, why you may/may not want to consider sandbox security, and more.
We will not have time to discuss or demonstrate clustering, load balancing, and replication, but can mention it only briefly. If that may be what you'd want to hear more about, please know this is not the talk for that. Perhaps a later talk.
But you will be pointed to many resources available for you to further investigate more on all the things we discuss (with a warning to be careful about older resources which describe an older but still-supported approach to multiple instances, from the CF 6.1 timeframe.)

CFMeetup: Introducing the Adobe ColdFusion Extensions for Eclipse (View video , Show Description )Whether you're already using Eclipse (via CFEclipse or not), or you've still not gotten into using it (or are waiting for Bolt), this talk if for you, if you don't know about the Adobe CF Extensions for Eclipse. Not to be confused with the CFEclipse plugin, the Adobe ColdFusion Extensions for Eclipse are a free set of very useful tools (for the free Eclipse editor) that many have missed, even if they do use CFEclipse. And if you don't yet use CFEclipse, these additional tools may offer features that might make you reconsider using Eclipse for CFML coding.
In this session, veteran CFer Charlie Arehart will introduce the extensions (not CFEclipse), including how to find and install the extensions from the Adobe site, as well how to use them to do many things: browse datasources and build queries, generate code using wizards, browse CFCs and web services, view log files, debug CF apps (discussed only briefly and supported only for CF8), and more.
Note that most of the features shown apply to if you're using CF7 as well. And since the upcoming new Adobe editor, codenamed Bolt, incorporates these same features (and many more, as discussed on the labs site), this talk will help you whatever your current or future plans.

CFMeetup: Sessions and Clients and Crashes, Oh My! (View video , Show Description )You may be suffering and not even realize it. As a consultant, I focus on helping people troubleshoot CF problems, and one of the most common (and least appreciated) problems people suffer are those related to having too many active sessions in memory or a high rate of creation/update of client variables (whether in registry or database). EVEN IF YOU'D SAY YOU DON'T USE SESSIONS OR CLIENT VARIABLES, this may impact you.
In this session, veteran CFer Charlie Arehart will explain the problem. Using live demonstrations and offering code you can use yourself for free, he'll show how to identify both the extent of and the cause of the problems, and various solutions. The concepts provided will apply to any version of CF (or BD or Railo).

Using Connect effectively for user group meetings (View video , Show Description )In this talk, veteran user group speaker and organizer Charlie Arehart
will share tips and traps in using Adobe Connect with user group
meetings. Whether you want to use it for an entirely online meeting, or
just to support either remote presenters and/or remote attendees, this
talk is for you. There are many aspects of using the tool (and managing
such meetings) which may not be obvious, and after running an entirely
online user group for two years, he has a lot of experience to share. Of
course, presenters will learn useful things, too.

CFMeetup: CF Free Clinic 1 (View video , Show Description )In the "CF free clinic", anyone can bring up a question or problem (anonymously if they wish, or by chat or by voice, or even by sharing their screen). I'll try to answer if I can, or another listener can try to answer (I can even give them the mic and let them show their screen if it would help). Finally, we can also help the caller by showing how to find the answer by searching various resources (which can be educational itself while watching). The goal isn't just to help the person with the problem, but to help everyone watching, by seeing how others solve problems.
