How to convert multiple DOCX files into PDF?

Oct. 5, 2011 - PRLog -- I’ve a Web-application which has to convert various DOCX files in PDF! I’ve googled a lot and found that many .Net components support only RTF and DOC  formats, but not DOCX.
As a result, I’ve chose UseOffice .Net:
This is my example of how you can convert DOCX files to PDF at server side:
       Dim u As New SautinSoft.UseOffice()
       'Path to any local file
       Dim inputFilePath As String = Path.GetFullPath(Path.Combine(Directory.GetCurrentDirectory(), "С:\Server\DOC.docx"))
       'Path to output resulted file
       Dim outputFilePath As String = Path.GetFullPath(Path.Combine(Directory.GetCurrentDirectory(), "С:\Server\Result.pdf"))
       'Prepare UseOffice .Net, loads MS Word in memory
       Dim ret As Integer = u.InitWord()
       'Return values:
       '0 - Loading successfully
       '1 - Can't load MS Word® library in memory
       If ret = 1 Then
           Return
       End If
       'Converting
       ret = u.ConvertFile(inputFilePath, outputFilePath, SautinSoft.UseOffice.eDirection.DOCX_to_PDF)
       'Release MS Word from memory
       u.CloseWord()
