MP3 STREAMING SERVER
Here is an application that uses coldfusion server to stream MP3 using an M3U file. An M3U file is basically just a playlist. In principle, if you send a *.m3u file to a media player, it should play the data in the m3u file. M3u file contains data like, location of the MP3.
Step 1!
Locate all your MP3 files and put them in a folder. In my case it was d:\MP3
Step 2 !
Open you web server (in my case it was IIS). Add the MP3 folder as a virtual directory to the web server. This will ensure that the streaming server will use HTTP port 80 for playing the MP3 on client side.
Step 3
Create the following file list and follow directions given below !!!
- Application.cfm
- Default.cfm
- Login.cfm
- LoginProcess.cfm
- Index.cfm
- DirListing.cfm
- CreateM3U.cfm
- Logout.cfm

An E - Rolodex System
Quick and easy way to sort and list your contacts by last names, in two really really simple steps. Almost everybody who uses a data-driven website has a database containing some information about the users. I had a database table called "contact" in which user's first name, last name, address, zip, email, phone, fax.... everything was listed. If you do have something like that and wish to draw and group your contacts by say last names, maybe you will find this tutorial useful.

Automatic Form Generator
This is not a tutorial as such, more like an application that you can put in a directory. It could boring if you use the CF editor, to pick "cfform" fill its attributes, then pick "cfinputs" one by one. fill out those attributes... one by one, then change tabs and pick the "submit" button... so on and so forth. Even if you code in a note pad, it might get lengthy to code individual element. Wouldn't it be nicer to code all these elements at once, then just copy the code and paste it in your editor?

A random password generator
RANDOM PASSWORD GENERATOR SCRIPT ! I know there is a random password tutorial here already. This is just another way to do the same. I think this is a little easier to understand. Refresh it to generate a new password string everytime !

Advanced Calculator
I have posted a "Basic Calculator" tutorial here. That was more like a representation of how you would calculate with a paper and a pencil. You provide INPUT A then a MATHEMATICAL OPERATION like a "+" or a "-" and then an INPUT B. This is more a represntation of how you would use a regular hand-held calculator complete with buttons for NUMBERS, OPERATIONS and CLEAR TEXT.

Breaking down your query results into pages (Paging Tutorial)
I havent come across a "paging" tutorial on this site. I know there are JavaScripts available that help you achieve this, and the DataSet object in VB.Net comes with paging. All you do is "enable paging". But how do you do it in ColdFusion ?

A DataSet just like VB.Net
This tutorial shows you how to create a "dataset" just like the one in VB.Net In VB.Net you would create a dataset with "edit" button in an extra column. Once you click "edit", you get an option to "update", "delete" or "cancel edit mode" This is just like a cfgrid tag. Although a cfgrid tag lets you bulk insert, bulk update or bulk delete, the dataset object does it one by one. But cfgrid is slower, and may give users Java errors, depending on their browser settings.

Dynamic time and date for your pages
Have you seen the "www.EasyCFM" page closely? On the main page, top right, there is a place for time, and top left a place for day-date. Ever wonder how Pablo does it ? This is not a ColdFusion tutorial. Its JavaScript.

ColdFusion MX 6.1 Installation on Linux (Ubuntu -- Hoary Hedgehog)
I have tried hoards of websites on how to install coldfusion on Fedora Core 3 with apache webserver. For some reason the connectors always failed. I had "Ubuntu" on my laptop, basically because "acpi" suspend/hibernate actually works. I decided I might try to install CF there to find out what was going wrong. Surprisingly everything worked like a charm. Make sure you use "apt-get install apache2" before you try this. BEST OF LUCK ....

Getting ColdFusion Studio for Linux
I like using HomeSite+ for windows, and I am getting used to Dreamweaver Mx. But I still need something just as good for Linux. For some reason, I couldnt get "wine and Dreamweaver Mx" to work. So I "Googled" a bit and stumbled upon Eclipse and cfEclipse. Here is how to set it up.

Breaking down your query results into pages (Paging Tutorial) Part-II
This is an extension to my last tutorial "Breaking down your query results into pages (Paging Tutorial)" which is posted here on www.easycfm.com In the last tutorial, you could retrieve a dataset with a, then use a technique to seperate the results over several pages. It simply ; - took the total "recordCount" - divided that with the "number of records per page" - then displayed the number of pages at the bottom of the table. This is a little more sophisticated than that. Read on...
