Unable to consume web service on Visual Studio 2005

[Former Member]

HI everyone, I got a problem. I am on a school project which uses a PDA to connect to the webservice. The PDA will uses the web service to retrieve values from SAP. I tried my webservice for a simple function like Login it is successful. But when i run my PDA emulator on visual studio it is unable to work. I am unable to solve this error, can anyone help me pls. Thank you:)

The following is my webservice coding

    <WebMethod(EnableSession:=True, Description:="This method is used to verify and retrieve a user info upon logging in")> _
 Public Function Login(ByVal Email As String, _
                                ByVal Password As String) As String


        Dim oCompany As SAPbobsCOM.Company
        Dim oRecSet As SAPbobsCOM.Recordset
        Dim LoginExist As String
        'Dim oDocument As SAPbobsCOM.Documents = Nothing

        'oDocument = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oDeliveryNotes)
        'oDocument. = SAPbobsCOM.BoDocumentTypes.dDocument_Items

        Try
            SetConnectionParam("S10036633", "SBODemo_SG", "manager", "manager", "sa", "P@ssw0rd")

            If ConnectToDatabase() Then
                oCompany = Session("g_CompanyConnection")
                oRecSet = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset)
                oRecSet.DoQuery("SELECT T0.[firstName] FROM OHEM T0 WHERE T0.[email]='" & Email & "'  AND  T0.[homeTel]='" & Password & "'  AND  T0.[position] IN (3,5)")

                If Not oRecSet.EoF Then
                    LoginExist = "True"
                Else
                    LoginExist = "False"
                End If

            End If
        Catch ex As Exception
            Session("g_LastErrorMsg") = ex.Message
        End Try
        Return LoginExist

    End Function 

This is my code in visual studio 2005

   Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click
        Dim localhost As New localhost.Service
        Dim dtLogin As String = ""
        Dim Username As String = ""
        Dim Password As String = ""

        Username = CType(txtUsername.Text, String)
        Password = CType(txtPassword.Text, String)
        dtLogin = localhost.Login(Username, Password)

        If dtLogin = "True" Then
            Dim form As New frmHome
            form.Show()
        Else
            MessageBox.Show("Invalid Username / Password")
        End If


    End Sub

Judy, please note:

This forum is dedicated to topics related to custom application development or deployment with Crystal Reports in .Net. This includes full versions of Crystal Reports as well as those versions of Crystal Reports bundled with Microsoft Visual Studio .Net.

Your query does not appear to be related to the above and if I am correct, you will have to post to an SAP(?) forum.
