For getting the file date(s) I wrote the following class in VB.NET (using VisualStudio), made a DLL of it and imported it using Tools>.NET DLL Importer in PowerBuilder 2019 R2:

"Imports System.IO 'File Class
Public Class CHilfsfunktionen

  Public Shared Function FileVersion(ByVal Path As String) As String(,)
        FileVersion = Nothing
        Dim fi As FileInfo = Nothing

        If Not File.Exists(Path) Then Return Nothing
        Try
            fi = New FileInfo(Path)

            FileVersion = {{"Directory", fi.Directory.FullName},
                           {"Full Name", fi.FullName},
                           {"Name", fi.Name},
                           {"Creation Time", fi.CreationTime.ToString},
                           {"Last Write Time", fi.LastWriteTime.ToString},
                           {"Last Access Time", fi.LastAccessTime.ToString}
            }
        Catch ex As Exception
            FileVersion = {{"Exception", ex.Message}}
        End Try

    End Function

End Class".

In my PowerScript script I could access the file dates afterwards the following way:

Application              gnv_thisApp
string                    gs_ThisAppPath
string                    lsm_exe[]
nvo_chilfsfunktionen nvo_help

gnv_thisApp      = GetApplication ()
gs_ThisAppPath = getcurrentdirectory () + "\" + gnv_thisApp.appname

nvo_help = Create  nvo_chilfsfunktionen
lsm_exe  = nvo_help.of_fileversion( gs_thisAppPath + ".exe" )

messagebox("", lsm_exe[4] + ": " + lsm_exe[10] + "~n" + &
                      lsm_exe[5] + ": " + lsm_exe[11] + "~n" + &
                      lsm_exe[6] + ": " + lsm_exe[12])

Hi Konrad;

  FYI: My framework grabs many aspects of the PB Application and logs these as part of it's "System to System" checking at App start-up. If you are interested, I can point you to the location of the code in the framework and you are moist welcome to grab any code that you need for your App's use as the framework is open source and free. Here are two examples:

IDE:

EXE:
