如何通过 VB 获得 google 翻译的结果？

从网上找了一个版本，源代码如下：

VB code:
Option Explicit

'Global DefLang As String
Const WebURL As String = "http://translate.google.com/translate_t"
Const SearchString As String = "result_box dir="
Const EndString As String = "</"


Public Function Translation(InputText As String, LangPair As String) As String
Dim TMPString As String
Dim StartPos As Long
Dim DebString As String
Dim InitString As String

If IsConnected = False Then
MsgBox "You don't have Internet connection!", vbInformation, "Translation"
Translation = ""
Exit Function
End If

'InputText
TMPString = GetHTMLfromURL(WebURL & "?langpair=" & LangPair & "&text=" & InputText)
InitString = SearchString & Chr(34) & "ltr" & Chr(34) & ">"

StartPos = InStr(1, TMPString, InitString, vbTextCompare)
If StartPos = 0 Then
Translation = ""
Exit Function
End If

DebString = Right(TMPString, Len(TMPString) - (StartPos + Len(InitString) - 1))
StartPos = InStr(1, DebString, EndString, vbTextCompare)
Translation = ReplaceHTMLString(Left(DebString, StartPos - 1))

End Function

Public Function ReplaceHT
