LINK error and CLSID

[phil007]

HI,
I am developing a dialog based application in VC++6.0 using DirectShow (DX8.1).
When I execute it, I get the following message :

error LNK2001: unresolved external symbol _CLSID_DivxG400
error LNK2001: unresolved external symbol _CLSID_DivxDecode
error LNK2001: unresolved external symbol _CLSID_CapSrcLogitech
...

Although the project settings entries are including strmiids.lib,
it occurs an error on the CLSID that I try to add in a source file.

This graph has been tested successfully with GraphEdit.

I've got an other question :
Is there a way to know the CLSID of a specific property page ?
I want to use the Logitech QuickCam but I've never found the CLSID of the page shown in GraphEdit (Filter Properties...).

Thanks for your answer.
