Hi All,

I am creating a .dll object from ColdFusion but I am getting the following error message.

"Class GenerateSQLReport not found in the specified assembly list. The assembly that contains the class must be provided to the assembly attribute."

The Process I have followed:

- Updated the ColdFusion 9.0.1

- Uninstall the  .NET Integration Service

- Install the .NET Integration Service for 9.0.1

- Run the code.

My Code is : "<cfobject type="dotnet" name="MDBDTable" class="GenerateSQLReport" assembly="#expandPath('./GenerateSQLReportDLL.dll')#">"

I got the following StackStrace:

Correct answer -__cfSearching__-

I was not able to call a dll .

After reinstalling the .NET Service I can able to create a dll object.(I have used this http://tutorial11.learncf.com/ ).

But, when I create a sample dll with the following code it throws the previous error.

.NET Code

-----------------

using System;

public class HelloWorldProc {  

     public HelloWorldProc()

     {    

     }   

 

     public string HelloWorld()

     {        

          return "HelloWorldProc:HelloWorld called and returns Hello world!";  

      }

}

I don't know .NET very well. If I am missing something please suggest.

Thanks


I don't know .NET very well. If I am missing something please suggest.

The CF code must include the full path to the class, including any namespace. When you create a C# project in Visual studio it typically uses the project name as the  "default namespace". So if your project is named "MyProject" the full path would be:

   <cfobject type="dotnet" class="MyProject.HelloWorldProc" ...>

This might be a dumb question, but have you verified that this assembly does, in fact, contain this class? How did you perform this verification?

I have verified the class of the .dll file  from the .net code.

class="GenerateSQLReport"

Is it a public class - and is that the full path (including namespace)?
