synchronize run methods vbscript - methods

Question

I have a problem. I need to throw some synchronized commands in vbscript (one Run method, Delete one and moveFile one) in every cycle to my loop. I don't know how I do it.
My code is that:
Public Function UnificarCRIs(ByVal path, ByVal FICRIEC, ByVal sessio, ByVal CIBAA)
Dim objFile, objCurrentFolder, filesys, origenFitxers
Dim FileName, WshShell
On error resume next
Set filesys = CreateObject("Scripting.FileSystemObject")
Set WshShell = WScript.CreateObject("WScript.Shell")
Set objCurrentFolder = filesys.getFolder(path)
For Each objFile In objCurrentFolder.Files
FileName = objFile
If (right(FileName, 4) = ".cri") Then
If filesys.FileExists(path & FICRIEC & sessio) Then
'WshShell.Run ("copy " & path & FICRIEC & sessio & "+" & FileName & " " & path & FICRIEC & sessio & "_tmp")
WshShell.run ("cmd /K " & "copy /Y " & path & FICRIEC & sessio & "+" & FileName & " " & path & FICRIEC & sessio & "_tmp",8,TRUE)
Set WshShell = Nothing
filesys.DeleteFile path & FICRIEC & sessio
'filesys.MoveFile path & FICRIEC & sessio & "_tmp", path & FICRIEC & sessio
Else
WshShell.run "cmd /K " & "copy /Y " & FileName & " " & path & FICRIEC & sessio,8,TRUE
Set WshShell = Nothing
End If
End If
Next
End Function

Answer 1

Read the docs for .Run completely and reflect on the bWaitOnReturn parameter.
Apology:
Sorry, I didn't read your code carefully enough. The .Run should wait. But I see that you use a global On Error Resume Next and param list () in
WshShell.run ("cmd /K " & "copy /Y " & path & FICRIEC & sessio & "+" & FileName & " " & path & FICRIEC & sessio & "_tmp",8,TRUE)
What happens, when you remove those mistakes? Are you sure, that you have a usable WshShell in the second pass thru the loop?
