Problem

Xiao Zhou colleagues a business trip editing graphics system reflects the Times "Objects in this class cannot be updated outside an edit session" error, the problem I found the next line is I find out the reasons for, and Oh! Procedural issues.

When a feature class participated in a topology (or Geometry Network) after the implementation of the feature classes to create elements, modify graphic elements or attributes may appear in this exception: 'Objects in this class cannot be updated outside an edit session'

Reason
This is due to ArcEngine License to use the application due to insufficient permissions. In ArcEngine application which need to be edited by ArcSDE License'ArcGIS Engine Enterprise Geodatabase ', or ArcEditor, or ArcInfo.

Solution
In ArcEngine application LicenseInitializer.InitializeApplication in the process increase the Geodatabase editing privileges.

Public   As Boolean

'... ...
licenseStatus = CheckOutLicensesesriLicenseProductCode.esriLicenseProductCodeEngineGeoDB

licenseStatus = CheckOutLicensesesriLicenseProductCode.esriLicenseProductCodeEngine

'... ...
End Function

As my colleagues in the field mission, the program can not modify, remove topological rules wrong, but this bug is to be submitted.

Public Function InitializeApplication(ByVal productCodes As esriLicenseProductCode(), ByVal extensionLics() As esriLicenseExtensionCode) As Boolean
        'Cache product codes by enum int so can be sorted without custom sorter
        m_requestedProducts = New List(Of Integer)()
        For Each code As esriLicenseProductCode In productCodes
            Dim requestCodeNum As Integer = CInt(code)
            If Not m_requestedProducts.Contains(requestCodeNum) Then
                m_requestedProducts.Add(requestCodeNum)
            End If
        Next
       
        AddExtensions(extensionLics)
        Return Initialize()
    End Function
