Changing The printer Port in the Registry.

I'm changing the port value in the registry for the default printer. However when you bring up the port details from printer properties, they don't reflect the new port in the registry?

I'm I missing something?


Thanks

Kev.

Code:

---

    Call SetKeyValue(HKEY_LOCAL_MACHINE, "SYSTEM\CurrentControlSet\Control\Print\Printers\Adobe PDF", "PORT", strPortValue, REG_SZ)




    Dim LngValue$
    Dim rtn As Long
    Dim lValue As Long
    Dim sValue As String
'    Call ParseKey(Subkey, MainKeyHandle)
    LngValue = vValueSetting
    If lRoot Then
      rtn = RegOpenKeyEx(lRoot, sKeyName, 0, KEY_WRITE, hkey)
      If rtn = ERROR_SUCCESS Then

            Select Case lValueType
                Case REG_SZ
                    sValue = vValueSetting & Chr$(0)
                    rtn = RegSetValueExString(hkey, sValueName, 0&, lValueType, sValue, Len(sValue))
                Case REG_DWORD
                    lValue = vValueSetting
                    rtn = RegSetValueExLong(hkey, sValueName, 0&, lValueType, lValue, 4)
                End Select
               
          If Not rtn = ERROR_SUCCESS Then
            If DisplayErrorMsg = True Then
                MsgBox "Error Message" & rtn
            End If
          End If
          rtn = RegCloseKey(hkey)
      Else
          If DisplayErrorMsg = True Then
            MsgBox "Error Message" & rtn
          End If
      End If
    End If
