Hello,

I got a C# program , which can iterate over a number of pdf files in a directory. I used the following code for the first document:
...
CAcroApp AcrobatApp = new AcroAppClass();
AVDoc = new AcroAVDocClass();
AVDoc.Open(filename1,"");
AcrobatApp.Show();
...

So far so good. Acrobat starts and shows the loaded document. The Code for stepping to the next document is:
...
AVDoc.Close(0)
AVDoc.Open(filename2,"");
...

The document is closed and the empty Acrobat window (same as if you open a PDF in Acrobat 9 and then select "File|Close" from the menu). Instead of using this empty frame the next "AVDoc.Open.." a new window is created for the next document.
Can I somehow tell Acrobat to open the new document in the "empty" Acrobat window instead of opening a new one?
(Might be a SDI problem of Acrobat 9, since the code worked well for all older versions of Acrobat using the MDI interface)

Thanks a lot,
Ren�
