This tutorial will show you how secure ways to obtain the ID of the record you inserted, not just the last ID inserted. The tutorial covers this technique in MS Access, MSSQL and MySQL.
This tutorial explains how to write a CFC to invoke and interact with Googles SOAP Search API to find your google ranking for your targeted keywords.
I labeled this tutorial as "Intermediate" but anyone could follow (even if that means cut/paste!)
Static HTML can help reduce the load on the server. This helps resources be used for other things that you may possibly need. Creating static HTML in ColdFusion is a simple task and can simply be done by following this tutorial.
A very simple tutorial that explains how to add information submitted from a form into a logging file. Very simple, yet lots of possibilities. Important for the beginning CFM programmer
This will retrieve the 9 day weather forecast for the specified ZIP code.
I wanted to create a tutorial on something that will make your life easier. This tutorial is on SQL Transaction logs and how to make them smaller. This will save you time and money because of disk usage! I hope this helps your site go faster!
Ever wanted to be like google and run your scripts without an extension? This tutorial shows you how with Apache or IIS!
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....
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.
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.
This is a custom tag application. The cf_QueryRender custom tag takes your query arguments and gives you a final page table and all...
This is a small application that shows you how to create an MP3 streaming server.
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.
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 ?
Someone on the forum posed a question a short while ago asking how to create a more advanced search function using a + symbol as a separator. So I created this advanced search function. This search function is just slightly better than a normal search as it adds the ability to separate two keywords with a + symbol. Lets start with the search form.
Not all queries can be saved as an application variable. For Queries that do not meet the checkpoints in my previous tutorial there is another way to improve performance. Query Caching is another way to save data and eliminate unnecessary queries. This is for queries that are more dynamic in nature.
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. Using this simple color picker, you can create admin areas that can allow you or your visitors to pick their own colors and the value is automatically inserted into a text field.
Quickly and easily sort and order records in your database using a cfswitch in your query. Great technique for admin areas of your site, or just allowing visitors to sort the fields they want.
