Adding support for automated tweets with OAuth

I commented on Ray Camden's blog entry, Adding support for automated tweets with OAuth
Ray, I've been struggling with this for a few days and really appreciate you posting your solution. I had looked at twitter4j, but rejected it in favor of working with the OAuth project on RIAForge (http://oauth.riaforge.org/). When I saw your blog post I looked at twitter4j again, this time using javaloader and was able to solve my problem. I may still continue looking at OAuth, but my production app is back up and running. Thanks again! -Ed

Renewing SSL Certificate on IIS 7 Woes

One of our Windows 2008 IIS 7.0 webservers had an SSL certificate on it that we renewed.  I thought I had it taken care of: I had generated the request, we submitted it to the authority, paid for it, received the new certificate and completed the request.  All good.  Right?  Wrong.

New in CFMX 6&7: What did you miss?

At lunch today I attended Charlie Arehart's CFUnited preview presentation, New in CFMX 6&7: What did you miss? online a la the ColdFusion Meetup Group. It looks like I'm really going to miss out by not attending this conference! Charlie has provided a loooooong list of both major features of CFMX 6 & 7 as well as not so major enhancements in CFMX 6 (no list for 7). Being only 30 minutes he was not able to go into detail on any of these items, but he sure wetted my appetite and gave me a lot to research. He started with an example of an enhancement that came out way back in ColdFusion 4.01 that is not widely known: ListQualify(), for example, can convert a list such as "red,blue,green" to 'red','blue','green' for use with a SQL clause WHERE IN(...)

Implementing Subversion w/ TortoiseSVN

I've known of the benefits of version control especially Subversion for a while now, but for whatever reasons, I hadn't made "the leap" until now. I bookmarked the series Configuring a Development Environment with Apache, Subversion, TortoiseSVN, and Subclipse most recently, but like many of my bookmarks it sat unread for a while. What is different is that Monday evening I began reading it and implementing it as I went along. I've read and worked through Parts 1-3 augmented with The ACME Guide and am now using a repository with one of my current projects. While the articles are great and were able to get me up and running, I have found I have a need for a quick reference while I am still getting comfortable with the process.

Development Directory Structure

While implementing version control, I changed several things in my development environment. One of those things is the directory structure. I did some reading online, especially ColdFusion MX Coding Guidelines - Structure: Application, Component, Tag etc (scroll down to the Directory Structure For Applications section). Most of what everybody else talked about referred back to this guide. The big question that I had as a developer was; how to handle multiple sites? The apparent consensus is to place each application in wwwroot whose parent is cfmxroot. Each application has its own webroot where the .cfm files go and other non-web folders. The overall development environment then has folders for supporting files within the cfmxroot. The following is the expanded structure including some folders which I probably won't use, but are there if I need them:

Submit CFCALENDAR onchange

I'm building an application that needs a calendar picker tool and I decided to check out the CFCALENDAR form control. It turns out that since it is a flash component, the onchange event uses ActionScript rather than JavaScript. This proved a bit frustrating for me since I knew zero ActionScript going into this and I was initially unable to find any help online. I eventually came across a page, Passing Variables Around - Flash to HTML and Back that talked about how to emulate a METHOD="GET" submit in ActionScript. I then learned about how AS names fields and some basic date functions and came up with the following code:
