30 Migrating ColdFusion 5 Applications

Incompatible example

The following example to retrieve ColdFusion mappings throws an error because

ColdFusion MX does not store ColdFusion mappings in the registry.

<cfregistry action = "get"

branch = "HKEY_LOCAL_MACHINE\SOFTWARE\Allaire\ColdFusion\CurrentVersion\

Templates"

entry = "/cfdao/" type = "String" variable = "RegValue">

Please create a CF Mapping named cfdao which points to your cfdao files before

trying to run this template.

</cfoutput>

</cfif>

Compatible example

To work around this, you can include error handling in your templates that would notify

the system administrator if a

cfinclude failed due to a missing mapping. In the event of

a missing mapping, the system administrator must create it in the ColdFusion

Administrator.

For more information on performing registry operations in ColdFusion MX, see

cfregistry in the CFML Reference.

Using ListSort() in ColdFusion MX

When sorting with textnocase in a descending order, ColdFusion 5 and ColdFusion

MX return the results in a different order. However, both are correct because in a

textnocase sort, “apple” is equal to “APPLE”.

In ColdFusion MX, a descending

textnocase sort returns the elements in the exact

reverse order as in an ascending

textnocase sort. This is different than in ColdFusion 5.

The following code produces different results in ColdFusion MX than in ColdFusion 5:

This code produces the following results for ascending and descending sort operations in

ColdFusion 5 and ColdFusion MX:

ListSort() in CFML Reference.
