Can I expose C# dll functions to IntelliSense in VFP 9? 1

[DanWalter]

Hi All:
I have developed a C# (VS 2008 class library project) DLL. This DLL is registered for COM Interop and is COM visible.

I can consume the DLL in VFP 9 using the CreateObject command, then invoking the methods in the DLL.

However, the DLL is not exposed to VFP IntelliSense. I get no list of functions/methods for the object and of course, no lists of parameters.

Is there a way I can expose these methods to IntelliSense in VFP 9?

TIA,
Dan

Yes you can. This is not clearly documented but you need to add ClassInterface attribute. ie:

using System;
using System.Runtime.InteropServices;

namespace DotNetUtils
{
    [ProgId("MyDotNetUtils.CB")]
    [ClassInterface(ClassInterfaceType.AutoDual)]
    [ComVisible(true)]
    public class MyUtilLib
    {
//...
    }
}

Dear Cetin Basoz:
Thanks so much for the tip - that rocks!

Because my application was marked for COM Interop, the [ComVisible(true)] attribute was true by default. Removing that attribute did no harm at all, and the code worked great!

Now I have an Intellisense-d DLL available to VFP.

Thanks again!
Dan
