When I close CAcroPDDoc, Why acrobat.exe NOT release resource?

[Tan_Lin@adobeforums.com]

Hi everybody.

I use CAcroPDDoc to open many PDFs, and read its page number.
Everytime I got the page number, I was close the CAcroPDDoc.
But acrobat.exe did not release resource. At last error happened!

What can I do?

CODE:
long CWorker::GetPagenum(CString strPDF)
{
long lNum;
CAcroPDDoc *pPDdoc=new CAcroPDDoc;
pPDdoc->CreateDispatch("AcroExch.PDDoc");
pPDdoc->Open((_bstr_t)strPDF);
lNum=pPDdoc->GetNumPages();
pPDdoc->Close();
delete pPDdoc;
}

Acrobat will release the document usually about 30 seconds after you ask it to...
