    My above question was solved when I used the menu item Website > Add reference > com tab > dso ole document properties reader 2.0.

     

    However, when I try to open a file using:

    dso.Open(FileName, True, DSOFile.dsoFileOpenOptions.dsoOptionOpenReadOnlyIfNoWriteAccess)

    I get this error:

    The name  is not valid. (Exception from HRESULT: 0x800300FC (STG_E_INVALIDNAME))

    Having trouble getting this too work.

    I've downloaded the ole file property reader linked at the bottom of the page. I registered the dll using regsvr32, but errors are being returned.

     

    Dim filename as string="c:\test\test.doc"
    Dim dso As DSOFile.OleDocumentProperties
    

    ' returns error "DSOFile.OleDocumentProperties not defined"
    
    

     dso = New DSOFile.OleDocumentProperties

    ' returns error "DSOFile.OleDocumentProperties not defined"
     dso.Open(filename.Trim, True, DSOFile.dsoFileOpenOptions.dsoOptionOpenReadOnlyIfNoWriteAccess)
    

    ' returns error "DSOFile not declared"

    
     Console.WriteLine(dso.SummaryProperties.Author)
    Console.WriteLine(dso.SummaryProperties.ByteCount)
    Console.WriteLine(dso.SummaryProperties.CharacterCount)
    Console.WriteLine(dso.SummaryProperties.CharacterCountWithSpaces)
    Console.WriteLine(dso.SummaryProperties.Comments)
    Console.WriteLine(dso.SummaryProperties.Company)
    Console.WriteLine(dso.SummaryProperties.DateCreated)
    Console.WriteLine(dso.SummaryProperties.DateLastSaved)
    Console.WriteLine(dso.SummaryProperties.LastSavedBy)
    Console.WriteLine(dso.SummaryProperties.LineCount)
    Console.WriteLine(dso.SummaryProperties.PageCount)
    Console.WriteLine(dso.SummaryProperties.ParagraphCount)
    Console.WriteLine(dso.SummaryProperties.RevisionNumber)
    Console.WriteLine(dso.SummaryProperties.Subject)
    Console.WriteLine(dso.SummaryProperties.Title)
    Console.WriteLine(dso.SummaryProperties.WordCount)
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    

     

    How do I use this library after downloading it?
