Using code line 30-59 and line 98-109 ?

From the looks of it, you are coding a Browser Helper Object for Internet Explorer. It is a COM object and is therefore treated as such. Do you know COM? If not, you need to learn.

In general, a method of the COM object is called via a pointer to an object of the class. In COM, you usually have interface pointers, although that's really just required for the consumer of the object (Internet Explorer or others in this case).

You already opened one topic with pretty much the same subject if I remember correctly ......

What is "ALT" from topic title ? I suppose do you mean ATL (Active Template Library) ....

If you use ATL, what version are you using ? From using macros like USES_CONVERSION I suppose you still using ATL3, which is a very outdated version ..... If you are using ATL7 or higher, then this macro is not needed.
