Calling a VFP DLL from a C# application

Steve Loader

All,

Does anyone on here have any experience of calling a VFP DLL from a C# application?

I've developed a VFP Multi-threaded COM server DLL, that simply accesses various Opera 3 VFP database tables.

I've written a VFP test harness that references the DLL, and calls various of its methods. It works successfully.

However, I want to write a C# test harness to do the same thing (i.e. reference the DLL, and call various of its methods).

I created a simple C# Console application, and referenced the VFP DLL.

I then thought, probably rather naively, that the C# code would be something like:

myVFPClass myObject = new myVFPClass

However, i get error "myVFPClass is a namespace but is used like a type".

I've Googled it, until I'm Blue in the face, but can't see what I'm doing wrong.

Does anyone have any experience of doing the above and, if so, can advise as to how I can resolve the above error?

Many thanks

Steve

Yes, I've done this successfully.  It's a while back, but looking at my code and yours, I think you need :- 

myVFPClass.myVFPClass myObject = new myVFPClass.myVFPClass();

I think the first myVFPClass is the namespace and the second is the interface

Let me know how you get on!
