VBScript equivalent to F5 key

I spend a considerable amount of time trying to come up with VBScript equivalent of F5 key for refreshing the desktop and as it turn out, SendKey "{f5}" method alone does not do the job. Below is the script, utilizing Windows Explorer shell command file (.scf)
that worked like a charm:

' Create explorer command file to toggle desktop window 
 Set objFSO = CreateObject("Scripting.FileSystemObject") 
 strFile= objFSO.BuildPath(objFSO.GetSpecialFolder(2), objFSO.GetTempName &".scf") 
 With objFSO.CreateTextFile(strFile, True) 
 .WriteLine("[Shell]") 
 .WriteLine("Command=2") 
 .WriteLine("[Taskbar]") 
 .WriteLine("Command=ToggleDesktop") 
 .Close 
 End With 
  
 ' Toggle desktop and send F5 to refresh desktop
 With CreateObject("WScript.Shell") 
 .Run """" & strFile & """" 
 WScript.Sleep 100 
 .Sendkeys "{F5}" 
 End With 
 ' Delete command file 
objFSO.DeleteFile strFile
