CFDocument in fontembed

Thu, 04 Apr 2013 08:52:00 -0700

Last 3 days, I'm about to generate one of our reports to PDF with cfdocument but I don't know why our unicode font is missing as displaying "blank" in cfdocument even this font is in my pc. That's why I request my junior to investigate the problem to be solved. After a day, she found how to display unicode font in cfdocument. First of all, we need to install font in our server first. Then, we need to go CFAdmin > Font Management and add installed font into coldfusion to be recognized. After all, we need to add fontembed="yes" in cfdocument as follow.

CFTransaction cannot work for different datasource

Sun, 04 Nov 2012 19:37:00 -0700

Today, I've found that CFTransaction cannot work for different datasource. This one is really bad for CFDevelopers like us. Because we need to use CFTransaction when we need to do long process for so many query transaction within our code with different datasource. [More]

Webservices without using cfinvoke

Tue, 14 Aug 2012 22:06:00 -0700

As we all know if webservices of another party using window NT authentication, we cannot use CFInvoke for calling webservices. At that time, we need another 3rd party webservices integrator for coldfusion to access another party. At that time, we need to use CFObject instead of CFInvoke.

My UDF is released at cflib

Tue, 24 Jul 2012 18:02:00 -0700

Today, I've received email from CFLib.org that my UDF called "getProfileStringUTF8". It supports to translate any unicode-based language instead of using GetProfileString which doesn't support Unicode (UTF-8). You can download and check this one here. getProfileStringUTF8

Replace Javascript Confirm box with CFMessagebox

Tue, 19 Jun 2012 02:24:00 -0700

In my previous post (here to view), I've mentioned how to replace Javascript Alert box with CFMessageBox. Here again, to replace Javascript Confirm box with CFMessage.


function DisplayMessageConfirm (obj, messageText) {
	var RandCount = Math.random();
	
	ColdFusion.MessageBox.create(obj + RandCount, 'confirm', 'CESID', messageText, onfinish, {width:300, modal:true});
	ColdFusion.MessageBox.show(obj + RandCount);
}

CFIDE with multiple instance

Fri, 23 Dec 2011 23:13:00 -0700

Today I got the problem that I cannot use following sentence in one of my instance.

And hit JS error and don't know why. That's why I just go viewsource and found that CFIDE is missing for one of my CF instances. I cannot convince why Adobe cannot include CFIDE for multiple instances installation. That's why I know there is two ways to solve this bug of Coldfusion multiple instance installation. [More]

Get IPv6 address

Sun, 27 Nov 2011 03:52:00 -0700

Today, I've found how to get IP address of IPv6. Because we're using IPv6 address in our office and normally so far to use for IPv4 in Window7. That's why I gotta retrieve address of IPv6. On the other hand, CGI variable can retrieve IPv4 address of client machine. How to get IPv6 is as follow. First of all, we need to create Java object first which called "java.net.InetAddress". Then, write as follow. [More]

I'm now planning to take Coldfusion 9 exam for my career enhancement. Because I'm Adobe Certified Expert in Coldfusion 8 and I feel like myself to take Coldfusion 9 either. Some people will argue that certificates are not needed if you really know of it but for new career, it's needed. When I want to apply for new job, I'm not sure whether the new employer know I really know Coldfusion or not without having certificate.

ListToArray and Looping in Array

Thu, 29 Sep 2011 17:25:00 -0700

Today I need to fetch data from *.csv (which has nearly 15,000 records) file and insert such data into our database. At that time, I need to consider how to retrieve data from this file and how to insert into our database. So, I need to consider which method I need to use between "looping in array" and "ListToArray". That's why I've wrote with "looping in array" first. Here is simple list data including in CSV file.

Merge Area Chart and Bar Chart in Coldfusion

Tue, 20 Sep 2011 21:32:00 -0700

These days I'm about to develop growth chart module for my current project enhancement. In this growth chart, I need to merge two chart series called area chart and bar chart to display patient percentile. In Coldfusion Chart, if we're trying to merge two chartseries, x-axis of both must be same records. If not, our chart might be displayed wrong data. Here is my sample coding of CFChart.

Playing with CFThrow

Tue, 19 Jul 2011 18:24:00 -0700

Today, I found that cfthrow is very useful to me for error handling in my project. Because prior programmer of my current wrote some funny code for error handling without using cfthrow. I'm not sure whether they don't know cfthrow or not. Honestly, I didn't know most of Coldfusion Tags and functions before I took CF8 exam. When preparing for CF8 exam, I know most of tags and functions of CF8. Thanks, CF8 exam. Ok, let's continue. Here is funny coding our prior programmer wrote. [More]

Query of query problem between Coldfusion 9 and Coldfusion MX 7

Thu, 14 Jul 2011 19:26:00 -0700

Today I've found the weird error in my project. It's because of "query of query" problem between Coldfusion 9 and Coldfusion MX 7. As Coldfusion developers know, one of the coolest features in CF is query of query and know how to use this one, either. But, being CF developer, we must know which features, functions, tags, issues, etc are fixed or missed in the every version of Coldfusion. For me, I can only know and approach which new features, functions and tags are available and being enhanced in the every version of Coldfusion except issues. [More]
