How to get pdf file page's information

[fuzezheng@adobeforums.com]

If one of the PDF file pages is rotated by 90 angles and becomes horizontal, It is still vertical when I print it out to be an image. So I want to know how I can get the page's infomation to judge it's vertical or horizontal (rotated or not) by coding. Thanks very much.

Download the Acrobat SDK and read the documentation.

What's wrong with the code below? Why does pAcroPDDoc.CreateInstance return E_NOINTERFACE?

#import "acrobat.tlb"

Acrobat::CAcroPDDocPtr pAcroPDDoc;
HRESULT hr = pAcroPDDoc.CreateInstance("AcroExch.FDFDoc");
if ( FAILED( hr ) )// hr = E_NOINTERFACE
{
return;
}

AcroExch.FDFDoc->AcroExch.PDDoc. It's OK now, thanks.
