Title: Smart or Stupid (CFLOOP as a GOTO)
Date: 06/28/03      19 Posts
Summary: A CFTRY block may be a good way to handle server-side form validation. If a form field is invalid, simply CFTHROW an error message. Alternative solutions, along with code snippets, are also included. Note that it's best practice to get server-side form validation working before adding JavaScript client-side form validation.
 
Title: Is There a Way to Test to See if a Data Source Exists?
Date: 06/28/03      15 Posts
Summary: In CF 5, you can test the existence of a data source by using an undocumented function:

   <CFIF CF_IsColdFusionDataSource("MyDSN")> 

In Windows, you can check the ODBC data sources in the system registry. You could also run a simple query inside a CFTRY block to CFCATCH a database error.
 
Title: RDS Error

Summary: A Homesite+ RDS connection error may be caused by a missing stub file, ide.cfm. The workaround is to create an empty ide.cfm file.
