Problems accessing some interface of the COM object using ASP
Posted: 1 Nov 2002
Hi,

I am running IIS 5.1 on Windows XP Professional with the latest patches installed.

I have a COM/ActiveX component from the client which has been tested using a Visual BASIC application. While all the interfaces seem to work well within the Visual BASIC application, some of the interfaces when invoked from ASP (using VB Script), using the same parameters do not return the same results.

For example, a search interface would return as many as 45 results within the VB application and 0 for the ASP.

A statistic page was set up, to verify the hits between the COM object and the backend. When the interface is being called from the VB Application it is generating hits but not when the page is called.

Are there any permission to be set for the application or on the web server?

Any help or pointers is deeply appreciated.

It is due to the way COM applications work

ASP is not a *perfect environment* to call a COM component. It is because ASP is actually based on scripting languages and scripting languages my friend don''t have power enough to do what you''d expect from C++ or VB.

Ask the person from whom you got this component and he might be better able to tell you what you should do.
