I am testing an ArcMap Extension that was written in .Net for ArcGIS 9.3.1 in ArcGIS 10. One of the custom commands opens the Attribute table for selected features. The command determines which layer the user wants to open attributes for and then calls the subroutine below to open the layers attribute table. When the ITableWindow2.Show(true) command is issued, ArcGIS 10 errors with "Atttempted to read or write protected memory". Any help would be greatly appreciated. Public Sub OpenSelectTable(ByVal layer As ILayer, ByVal SELSET As Boolean, ByVal papp As IApplication) Try Dim pMxDoc As IMxDocument Dim pLayer As ILayer Dim pStandaloneTable As IStandaloneTable Dim pTableWindow2 As ITableWindow2 Dim pExistingTableWindow As IDataWindow2 ' 'Get the selected item from the current contents view pMxDoc = TryCast(papp.Document, IMxDocument) pTableWindow2 = New TableWindow ' Determine the selected item's type ' Exit sub if item is not a feature layer or standalone table 'Continue = False If TypeOf layer Is IFeatureLayer And layer.Valid Then 'A FeatureLayer pLayer = layer pExistingTableWindow = TryCast(pTableWindow2.FindViaLayer(pLayer), IDataWindow2) ' Check if a table already exists; if not create one pTableWindow2.Layer = pLayer ElseIf TypeOf layer Is IStandaloneTable And layer.Valid Then ' A standalone table pStandaloneTable = TryCast(layer, IStandaloneTable) pExistingTableWindow = TryCast(pTableWindow2.FindViaStandaloneTable(pStandaloneTable), IDataWindow2) ' Check if a table already exists; if not, create one pTableWindow2.StandaloneTable = pStandaloneTable End If pTableWindow2.TableSelectionAction = esriTableSelectionActions.esriDrawFeatures pTableWindow2.ShowSelected = SELSET pTableWindow2.ShowAliasNamesInColumnHeadings = True pTableWindow2.Application = papp pTableWindow2.Show(True) Catch ex As Exception MsgBox("Error support/openselecttable: " & ex.Message) End Try End Sub
