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...

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 ....

The principle of this tutorial is similar to "Dynamic time and date for your pages" tutorial. Except that this one generates messages, and that one updated time. Read on, you will get the hang of it....

Quick and easy way to sort and list your contacts by last names, in two really really simple steps.

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 ?

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.

One thing I am always trying to do is speed up my applications. As my site grows in size and complexity I find that I spend a fair amount of time re-coding pages because of a new technique I just learned. I wish I had learned about these techniques long before, and thereby allowing me to create more effective code. In this tutorial I'll try to explain some problem areas that I have identified, and some of the things you can do to improve performance.

Sometimes, you want to be able to change the color of something on your page. Be it one item, or every item on the page.
