Scripting and objects with multiple interfaces

Alessandro Federic #1 / 5	Scripting and objects with multiple interfaces Hi everybody, I developed a set of COM objects with a number of interfaces. How do I get access to one of the interfaces implemented like in normal applications I would do trought QueryInterface? It looks like it doesn't work in ASP. Now, I added a method that returns an IDispatch defined as GetRef(GUIDID : widestring) : IDispatch and this is practically identically to the Server.CreateObject method... How is it possible that Server.CreateObject works and mine doesn't? The objects works fine in a normal exe, it is only in ASP that doesn't. Thanks

Ryan N #2 / 5	Scripting and objects with multiple interfaces To the best of my knowledge-and if memory serves-scripting environments like ASP require you to implement the IUnknown interface-something VB generally takes care for you.

Ryan N #4 / 5	Scripting and objects with multiple interfaces Thanks for the clarification. Take this with a grain of salt-I heard this at a VBITS session held by a Developmentor.com guy-but in ASP you can not access custom interfaces only the IDispatch interface.

Alessandro Federic #5 / 5	Scripting and objects with multiple interfaces Thanks for the links. EXTREMELy nice, expecially the article linked at the end of the one you mentioned. Funnily I implemented that solution myself and now works fine. Thank you very much for your time.
