Read or Write OLE File Property

Here are the steps to Read or Write the properties of files [Title, Subject, Author and Comments]

Download and install DsoFileSetup_KB224351_x86.exe from http://www.microsoft.com/downloads/details.aspx?FamilyId=9BA6FAC6-520B-4A0A-878A-53EC8300C4C2&displaylang=en

- Add reference to C:\DsoFile\dsofile.dll to your project (this is the default location)

 

private void Button1_Click(object sender, EventArgs e)
{
  //This is the PDF file we want to update.
  string strFilename = @"c:\Test.pdf";
  //Create OleDocumentProperties object.
  DSOFile.OleDocumentProperties dso = new DSOFile.OleDocumentProperties();
  dso.Open(strFilename, false, DSOFile.dsoFileOpenOptions.dsoOptionOpenReadOnlyIfNoWriteAccess);


  dso.SummaryProperties.Title = "Test Title";
  dso.SummaryProperties.Subject = "Test Subject";
  dso.SummaryProperties.Author = "Test Author";
  dso.SummaryProperties.Comments = "Test Comments";


  dso.Save();
  dso.Close(false);
}
