using XPDF command line in .NET, how to set a long file path ?

In VB.NET I am able to use PDFtoText.exe to extract a file with

   Sub Pdf2Txt(ByVal options As String, ByVal pdfFile As String, ByVal txtFile As String)
        Dim arguments As String = options & " " & pdfFile & " " & txtFile
        System.Diagnostics.Process.Start("pdftotext.exe", arguments)
    End Sub

Open in new window


I call it with,
Pdf2Txt("-layout", "C:\xpdf\dstm270224.pdf", "")

Open in new window


It works fine with a simple path like "C:\xpdf\" But I need to point to paths with more than one directory,  such as "C:\Incoming\PDF\June 18, 2015\". When I make that change, it no longer works.  How can I get pdftotext.exe run with longer file paths?

Thanks.

You need to surround the path with quotes because it's got spaces in it:

Sub Pdf2Txt(ByVal options As String, ByVal pdfFile As String, ByVal txtFile As String)
    Dim trimmedPdfFile As String = pdfFile.Trim(""""c)  ' Remove existing quotes
    Dim trimmedTxtFile As String = txtFile.Trim(""""c)  ' Remove existing quotes
    Dim arguments As String = options & " """ & trimmedPdfFile & """ """ & trimmedTxtFile & """"
    
    System.Diagnostics.Process.Start("pdftotext.exe", arguments)
End Sub

Open in new window


This is a requirement of Windows, not of VB.NET.
