怎样取得WEBSERVICE的返回值？B4A

我用vb.net做了个webservice,再用vb.net写的程序去调用webservice,一切正确。

我想在BASIC4ANDROID中调用，确不成功。

webservice中代码：
Public Function login(pUser As String, pCode As String) As String
Return pUser & "#" & pCode
End Function

B4A中代码：
Sub btnLogin_Click
Dim job As HttpJob
job.Initialize("login", Me)

job.PostString("http://***/webims.asmx","puser=aaa&pcode=bbb")
End Sub

Sub JobDone(Job As HttpJob)
If Job.Success = True Then

Msgbox("登录成功!","")
Msgbox(Job.GetString,"")
Else
Msgbox("系统登录错误!","")
End If
Job.Release()
End Sub

求高手指点
