我想知道这种语言吗？

Question

我正在处理一个新项目，但是我不知道用来编写代码的语言吗？ 关于RFgen软件。

Private Sub txtMCU_OnEnter(ByRef Rsp As String, ByRef Cancel As Boolean, ByRef ErrMsg As String)
  On Error Resume Next

  Dim sMCU     As String
  Dim sCompany As String

  If (Len(Rsp)=0) Then Exit Sub

  Cancel = True

  If Not oSO.validate.BranchPlant(oVar,Rsp, sMCU, sCompany) Then Exit Sub

  oVar.tmCO  = sCompany
  oVar.tmMCU = sMCU

  Cancel = False
End Sub
