Hi friends ,

i've a strange problem.I use VB.NET

I declare and instance any DI object variables like "Company","Business Partners" and others.

While in normal procedures their values are recognized,in the Application_ItemEvent() and called functions they seem to lose their value...

My tool recognizes with (intellisense)the object, but in the runtime it seems not regognize the object....a little example :

I make an instance of a new company variable.

I set the properties and then connect it.

It works well until the VB procedures work,but then ,when Application_ItemEvent() takes place,it is not recognized.

I tried to declare a company object in this last Sub Application_ItemEvent() giving it the value of the ,but this last one works properly ,instead the new object seems empty.

I tried everything,

Can you help me please??

Thenk you

Hi Giammichele, your connection is bad!

You use the connection Single Sign On.

Ciao Giammichele, tu devi usare la connessione Single Sign On che ti allego sotto in VB.NET:

Public sCookie As String

SboGuiApi = New SAPbouiCOM.SboGuiApi

StringaConnessione = Environment.GetCommandLineArgs.GetValue(1)


applic = SboGuiApi.GetApplication()

oCompany = New SAPbobsCOM.Company

sCookie = oCompany.GetContextCookie

sConnectionContext = SBO_Application.Company.GetConnectionContext(sCookie)

If oCompany.Connected = True Then


End If

If Not oCompany.SetSboLoginContext(sConnectionContext) = 0 Then

SBO_Application.MessageBox("Impossibile stabilire una connessione")


End If

oCompany.UseTrusted = False

If Not oCompany.Connect = 0 Then

SBO_Application.MessageBox("Impossibile connettersi al database")


End If

Best Regards

Visual studio.NET

XP professional

SAP Business one 2004 A (6.70.165) DEMO

this is my app code:

Public Class Form1

Inherits System.Windows.Forms.Form

Dim WithEvents a As SAPbouiCOM.Application

Dim compagnia As New SAPbobsCOM.Company

Dim bp As SAPbobsCOM.BusinessPartners

Dim txtcardname As SAPbouiCOM.EditText

Dim frmUnico As SAPbouiCOM.Form

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim gui As New SAPbouiCOM.SboGuiApi


a = gui.GetApplication

compagnia.Password = a.Company.UserName

compagnia.UserName = a.Company.UserName

compagnia.Server = "rossini"

compagnia.CompanyDB = "ROGA2"


Dim path As String

Dim xmlD As New MSXML2.DOMDocument

path = System.Reflection.Assembly.GetExecutingAssembly.Location

path = path.Substring(0, path.LastIndexOf("bin")) & "form2.srf"



bp = compagnia.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oBusinessPartners)

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

MsgBox(compagnia.Server) '------ (WORKS!!!!)----


a.MessageBox(bp.CardName) '------ (WORKS!!!!)----

MsgBox(bp.CardName) '------ (WORKS!!!!)----

End Sub

Private Sub a_ItemEvent(ByVal FormUID As String, ByRef pVal As SAPbouiCOM.ItemEvent, ByRef BubbleEvent As Boolean) Handles a.ItemEvent

Select Case pVal.FormType

Case 134

Select Case pVal.EventType

Case SAPbouiCOM.BoEventTypes.et_FORM_LOAD

End Select

Case 2000003000

Select Case pVal.EventType

Case SAPbouiCOM.BoEventTypes.et_FORM_LOAD

Dim d As New SAPbobsCOM.Company

frmUnico = a.Forms.Item(pVal.FormUID)

frmUnico.Title = "New form XML"

txtcardname = frmUnico.Items.Item("txtCN").Specific

Case SAPbouiCOM.BoEventTypes.et_CLICK

Select Case pVal.ItemUID

Case "cmdClic"

If pVal.Before_Action = True Then

a.MessageBox("called event on click chiamato") '------ (WORKS!!!!)----

a.MessageBox(compagnia.Server) '------ (*****NOT WORKS******)----


a.MessageBox(bp.CardName) '------ (*****NOT WORKS******)----

txtcardname.Value = bp.CardName '------ (*****NOT WORKS******)----

End If

End Select

End Select

End Select

End Sub

End Class

Could it be a limitation of SBO 2004 DEMO?

I think I can't manage DI objects from UI.

I'm wrong?
