Hi, everyone,

I am developing an application using MSAA and PDF DOM. One function that I have to realize is to highlight some
given text (form MSAA's IAccessible node).

I want to use PDF DOM's "ISelectText" interface
(ISelectText->selectText(long startID, long startCharIndex, long stopID, long stopCharIndex)).

I get an IAccessible node pointer first, save it to "pAcc", then I use
"hr = pAcc->QueryInterface( IID_ISelectText, (void**) & pISelectText );" to get "ISelectText" interface.

The result is that if I only install "Adobe Reader 7.0", I always get an "Interface is not supported " error(
The error code is -2147467262). However, after installing "Acrobat professional 7.0 tryout", the program can
run normally.

Is there anyone who knows the reason? Is installing "Acrobat professional 7.0" required for using both
MSAA and PDF DOM?

Any suggestion or hint will be useful.

Thanks a lot!
