Not sure I can help Gary, not really having done COMInterop with VFP, but let me ask a question. Have you gotten this to work prior to trying to encapsulate everything with this wsResponseHandler class? Can you post some of *that* code?

>In most (but not all) cases the Web Service returns an object that has a return code and an array of "entity" objects which vary depending on the call made. Where the Web Service does not return an object I would like to convert the response to that VFP gets as standard response every time. Also the call to the Web Service may fail in which case I want to store my own ReturnCode and ErrorMessage.
