Thanks.

After I installed "Acrobat professional 7.0(TryOut)", the QueryInterface succeeded when running Adobe Reader. So I wonder
whether installing "Acrobat professional 7.0" is required for using both MSAA and PDF DOM. There was a very strange phenomenon that if I only installed "Adobe Reader7.0", I could get the "IPDDomDocument" pointer successfully and I could also get the associated "IPDDomNode" and "IAccessible" pointer successfully. Only did I use the "IAccessible" pointer to query for the "ISelectText" interface, the QueryInterface failed. The "ISelectText" is an interface exported by the IAccessible objects. Maybe the problem has something to do with the support for MSAA of Acrobat?

If there was an installation problem, then what may it be? Had it something to do with the registry table?
I have modified and tested the program many times, but still I could not find the reason.
