CF8 Accessing .NET DLLs Tutorial

ColdFusion Tutorial #11

This tutorial provides an example of Coldfusion 8 and .net integration.

demo.cfm

This page contains the form for the Math example and the button for the Query example.

This Template is just the entry form for the action page, this page contains the two text boxes one for a number and another one a another number.

Clicking the Calculate Button the action will execute the .net method selected from the dropdown list.

Clicking the DB Example Button the .Net method will be executed that will fetch the data from the Access databsae.

cfsampleaction.cfm

This is the action page that calls the .NET methods from the dll.

To access the .net methods first we need to create an object for the .Net Class , after creating the object we can access the methods in that class .
Following is a sample code snippet for accessing the .net methods from coldfusion.

cfsample.cs

This is the C# code for the DLL. The compiled DLL and Access DB used is available in the download.

Below are the steps to run this example locally

1. Copy the Access MDB file into a directory, you need to specify this directory in the CfSample.cs class file.
2. Create the .Net Class Library in Visual studio 2005 by changing the path in the CfSample.dll class file.
3. Compile the Visual studio solution which will create the DLL
4. Copy the generated DLL file into the folder with the ColdFusion code
5. Call the .NET methods from ColdFusion as described above.

Do you know if this can be done with a VB.NET assembly, and do you know of, or have any examples of the VB.NET code that will work for that? Thanks for the excellent tutorial.
