Get OCX version

I found this on my own.  I'm checking to see if the results are the same.

Here's VB.NET Sample code. I tried to pick OCXes I thought would be on your system.  It shows the "Product Version", not the "File Version", at least in cases like comdlg32.ocx.

comdlg32.ocx
  File    Version: 6.00.88.77
  Product Version: 6.00.8877

--- VB.NET ---

    Public Shared Sub Test_GetFileVersion()
        Dim filenames As String() = New String() { _
            "%systemroot%\Notepad.exe", _
            "%systemroot%\comctl32.ocx", _
            "%systemroot%\comdlg32.ocx", _
            "%systemroot%\mci32.ocx", _
            "%systemroot%\MSCOMM32.ocx", _
            "%systemroot%\mswinsck.ocx", _
            "%systemroot%\richtx32.ocx", _
            "%systemroot%\sysinfo.ocx", _
            "%systemroot%\sysmon.ocx", _
            "noSuchFile.ocx" _
            }

        For Each filename As String In filenames
            Try
                ' Get the file version for the notepad.
                Dim myFileVersionInfo As FileVersionInfo = FileVersionInfo.GetVersionInfo( _
                    filename.Replace("%systemroot%", System.Environment.SystemDirectory))
                ' Print the file name and version number.
                Debug.WriteLine("Filename: " & filename & System.Environment.NewLine & _
                    "  File: " & myFileVersionInfo.FileDescription & System.Environment.NewLine & _
                    "  Version number: " & myFileVersionInfo.FileVersion)
            Catch
                Debug.WriteLine("File: " & filename & " -- not found.")
            End Try
        Next
    End Sub

--- Output ---

I added a little driver to your code, and tried it.
It does indeed produce the same results.
Thanks for the effort.
