>If I am understanding correctly, based on what you, Ed R. and Erik have said, I should have created a COM component in C++ ATL that is capable of being instantiated in a web page using Createobject() in VBScript. The DLL currently very simple with only a single function containing one API call in it. It has been tested successfully in VB and VFP.

IE returns "Error: ActiveX component can't create object: 'SysData.IssSysData'" at the Createobject( "SysData.IssSysData" ) statement.

I am responding because you CC'd me in the message. I stated earlier that I had never tried this, so I don't have any technical input to add but...

FWIW, I have never tried this because it doesn't make any sense to me, for the same reasons that ActiveDocuments don't make sense: If your browser application requires components to be installed on the client machine, what is the advantage to using a browser interface at all? Why not build a VFP interface?
