>>It is actually an ATL COM DLL I created in VC++. I used the "Simple Object" object which I'm wondering might be the problem, thinking I needed the "Internet Explorer" object instead. It is an invisible object for obtaining User/Machine info that will be used in an Intranet scenario, so we should be able to have the object already on most users' machines.

Please excuse my persistence ( and apparent ignorance ) here, I must be missing something, either on the C++ end or the IE end of things.

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.

However, there must be something you all think I know that I must not know, because I cannot get the object to instantiate in a web page on my local machine that built the DLL. IE returns "Error: ActiveX component can't create object: 'SysData.IssSysData'" at the Createobject( "SysData.IssSysData" ) statement.

The only article I could find in MSDN on this error ( http://msdn.microsoft.com/library/devprods/vs6/vbasic/vbenlr98/vamsgcantcreateobject.htm ) listed the following possible causes:

"Class isn't registered" ( It was built on this machine and as a double-check I copied the DLL and typelib to System32, re-registered and retested in VFP )

"A DLL required by the object can't be used, either it can't be found, or it was found but was corrupted" ( same as above, built and tested on this machine )

"The object is available on the machine, but it is a licensed Automation object, and can't verify the availability of the license necessary to instantiate it" ( When developing the object I did not specify any licensing requirements )

"You are trying to use the GetObject function to retrieve a reference to class created with Visual Basic" ( not using GetObject and not a class created with VB )

"Access to the object has been explicitly denied" ( I.e. the object is being used and is not available. Been tried many times with nothing else accessing it. If it's this, I don't know why )

Sorry I have had to post so many times on what is, I'm sure, a simple issue. Thanks for the patience.
