Read or Write OLE File Property

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

- 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";


If you want run the exe of this application in other system, you have to register dsofile.dll.
For that copy dsofile.dll in that system and in command prompt navigate to the directory where the dsofile.dll is present and run the regsvr32 command like below.

regsvr32 dsofile.dll
