Show property page of filter inserted from file

[GoogleCodeExporter]

What steps will reproduce the problem?
1. insert filter from file
2. click properties of the filter
3. no property page is loaded

What is the expected output? What do you see instead?
There should be the property pages of the filter.

Solution:
because the the property page is not registered, it can't be loaded with 
CoCreateInstance. The property page needs to be loaded directly from the dll 
like the filter.
