How to depict a changing doc name in VB hyperlink script

[HannahMerchant]

I am trying to hyperlink PDF Floor Plans through Facility Number in VB Script Field Calculator.

My issue is that there are about 859 Floor Plans and each has a different name but starts with a Facility Number.  I have no issue matching the Facility Number but what do I do about the varying string description that vary in length and contain numbers.

Example:

Facility Number = A123

Floor Plan = A123_Admin_Hall_2016.pdf

This is what I have so far, how do I incorporate the string?? Are there wild card characters I can use?

"S:\DPW\Eng Record Management\Floor Plans" & [facilityNumber] & .pdf"

Thanks!!!

I am assuming that you are searching a directory for the Plan files......

Here is an Idea to get you started...this if not very efficient but I do not have a lot to go on but guesses:

Imports System
Imports System.IO
    Function GetFileInfo(FacilityNumber as string) as string
     Dim GFI as string
     GFI = ""
     ' Make a reference to a directory.
      Dim di As New DirectoryInfo("S:\DPW\Eng Record Management\Floor Plans\")
      ' Get a reference to each file in that directory.
      Dim fiArr As FileInfo() = di.GetFiles()
      ' Display the names of the files.
      Dim fri As FileInfo
      For Each fri In fiArr
          if left(fri.Name,3) = FacilityNumber then
              GFI = fri.name
              exit for
          end if
     Next fri
     if GFI = "" then
        GetFileInfo = "No Plans Found"
     else
        GetFileInfo = GFI
    End Function
