title: Powerbuilder PDF from blob
body: <p>I tried to use the control "OLE database Blob" from Datawindow to show PDF directly from Oracle database. I used OLE class "AcroExch.Document.11 Adobe Acrobat Document". My problem is when I try to show old PDF. That PDF I can download directly from the database with database tool Connector "PL/SQL Developer" and open with Adobe Acrobat with any problem. But the new saved PDF row used the ole control I can´t open the PDF. <a href="https://i.stack.imgur.com/h9DrI.png" rel="nofollow noreferrer">Error message from Adobe when trying to </a></p>
  
  <p>But I don´t have the same problem when I run my PowerBuilder app ... Is work correctly. I check the DB and I see the new rows inserted with Ole controller have more data if I diff data between old and new PDF(I used same pdf file) </p>
  
  <p>I ask if somebody know Why happen? Is it possible to access to data through code and process the blob data to convert the old pdf to the new pdf format? </p>
  
  <p>Thanks,</p>
