how can i get author, comments, ... from a file ?

[Raute50]

i tried to adapt the information from the VeryQueryValue Page and your post, but unfortunately i did not get the 'comments' Information

i used the following lines:

/* when i looked with my debugger on the lpFfi-entries, there is nothing usefull inside */
VerQueryValue( lpVersionInfo, TEXT("Comments"), (LPVOID*) &lpFfi, &uLen);

/* at the opposite: with the following line i got some information ... specially the 'version' information, after some more work i shown i the first post */
VerQueryValue( lpVersionInfo , _T("\\") , (LPVOID *)&lpFfi , &uLen );


what is the fault in my proceeding ?
