Hi Experts,

One of my users has struck a problem with my VB6 application.
This code works fine on dozens of sites.

On his PC:
     App.Path = "C:\Program Files\circly5"
     strDataPath = "C:\Program Files\circly5\data"

The error message is:

Copy failed. Access is denied.
"C:\Program Files\circly5\circ32.pif","C:\Program Files\circly5\data\circ32.pif"


RetVal = CopyFile(App.Path & "\circ32.pif", strDataPath & "\circ32.pif", False) 'Overwrite if file exists (20061116)
        If RetVal = 0 Then  ' failure
            '20051117: added code to output error message corresponding to Err.LastDllError
            Dim strErrorMessage As String
            strErrorMessage = ""
            If Err.LastDllError <> 0 Then
                strErrorMessage = strGetErrorMessage(Err.LastDllError)
            End If
            strMessage = "Copy failed. " & strErrorMessage & vbCrLf & chrCommandLineDelimiter & App.Path & "\circ32.pif" & chrCommandLineDelimiter & "," & chrCommandLineDelimiter & strDataPath & "\circ32.pif" & chrCommandLineDelimiter
            MsgBox strMessage, vbInformation
            Logger.Log 1, strMessage
         Else  ' success
            'PrintToDebugFile "Copy succeeded."
        End If

That error usually has something to do with user privileges but it can also be caused by another application that might have the original file open. In this case you may have a handle open to the file and copyfile will fail if you don't have any shared permissions.
I am not sure what the number '20051117' means but the actual error number for Access Denied should be 5 if I can recall.
