Dex2 - The access to field(s) denied.
Options
Hi, got error when trying dex2 examples. Everything is OK when using API from within Excel, but getting "The access to field(s) denied" error from Dex2 C# sample application. Why it happens? See the screenshot below.

You are trying to use the new set of fields (TR.<fieldname>) with the old initialisation routine. In order for this to work, you need to change the CreateDex2Mgr() initialisation routine.
Instead of:
MyDex2Cookie = MyDex2Mgr.Initialize();
You need to have:
MyDex2Cookie = (MyDex2Mgr as IDex2Mgr2).Initialize(DEX2_MetadataCaller.DE_MC_ADC_UNKNOWN);

The correct initialisation routine for VB .NET will be the following:
_dexCookie = DirectCast(_dexMgr, Dex2.IDex2Mgr2).Initialize(Dex2.DEX2_MetadataCaller.DE_MC_ADC_UNKNOWN)
Full sample below:
Private _api As EikonDesktopDataAPILib.EikonDesktopDataAPI
Private _dexMgr As Dex2.Dex2Mgr
Private _dexCookie As Long
Private _rdata As Dex2.RData
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
_api = New EikonDesktopDataAPILib.EikonDesktopDataAPI
AddHandler _api.OnStatusChanged, AddressOf Api_OnStatusChanged
_api.Initialize()
End Sub
Private Sub Api_OnStatusChanged(ByVal eStatus As EikonDesktopDataAPILib.EEikonStatus)
If eStatus = EikonDesktopDataAPILib.EEikonStatus.Connected Or eStatus = EikonDesktopDataAPILib.EEikonStatus.LocalMode Then
_dexMgr = _api.CreateDex2Mgr()
_dexCookie = DirectCast(_dexMgr, Dex2.IDex2Mgr2).Initialize(Dex2.DEX2_MetadataCaller.DE_MC_ADC_UNKNOWN)
_rdata = _dexMgr.CreateRData(_dexCookie)
AddHandler _rdata.OnUpdate, AddressOf RData_OnUpdate
With _rdata
.InstrumentIDList = "TRI.TO"
.FieldList = "TR.ISIN"
.Subscribe(False)
End With
End If
End Sub
Private Sub RData_OnUpdate(ByVal dataStatus As Dex2.DEX2_DataStatus, ByVal [error] As Object)
Dim i As Long, j As Long
For i = LBound(_rdata.Data, 1) To UBound(_rdata.Data, 1)
For j = LBound(_rdata.Data, 2) To UBound(_rdata.Data, 2)
Debug.Print(_rdata.Data(i, j))
Next j
Next i

Thank you! It works.
