Don,
This is basically what we're doing with ASP - we're sending the ASP Response, Request, and Session objects thru asp.dll(isapi) up to the VFP MTDLL to be manipulated in VFP code. We've got some other papers dealing with C++ to VFP on our resource page at http://www.activevfp.com

>The baseline of research I had was the FoxISAPI.dll to better understand some of the mechanics behind the operations and all the way to the point of setting up the VARIANTARG class as a parameter to the IDispatch / DispMethod.Invoke() call. The FoxISAPI does some converting of strings to a "bstr" data type and all is ok there (understanding what, but not the why).

>My ultimate goal, however, is to pass another object up to the VFP handler. So, is it possible to pass a pointer to the pECB (Extension_Control_Block) object to Visual FoxPro Component Object Model server so I can make use of things like GetServerVar, WriteClient and ReadClient methods??? If so, how, if not, what alternatives should I consider....
