Trying to remove a featureclass layer in PGDB, then copy a FGDB layer back to the PGDB.

Question asked by NikAries on Oct 2, 2014

Here is the VB.NET code;

        Dim strfcname As String = ""

        Dim GP As Geoprocessor

        Dim CopyFeatures As ESRI.ArcGIS.DataManagementTools.CopyFeatures

        Dim DeleteLayer As ESRI.ArcGIS.DataManagementTools.Delete

        Dim ITrack As ESRI.ArcGIS.esriSystem.ITrackCancel = Nothing

        Dim copied As Integer = 0

 

                        strfcname = row("FCNAME").ToString

                        LogDetails("Append " & strfcname & " from Mobile Server FGDB to " & PersonalGeodatbaseName & "\Geographics_GDA94_srid5\" & strfcname)

                        GP = New Geoprocessor

                        GP.OverwriteOutput = True

 

 

                        Try

                            LogDetails("Deleting  " & strfcname & " from " & PersonalGeodatbaseName)

                            DeleteLayer = New ESRI.ArcGIS.DataManagementTools.Delete()

                            DeleteLayer.in_data = PersonalGeodatbaseName & "\Geographics_GDA94_srid5\" & strfcname

                            'DeleteLayer.data_type = ""

                            'DeleteLayer.out_results = ""

 

 

                            RunTool(GP, DeleteLayer, ITrack)

                            LogDetails("Delete of " & strfcname & " from " & PersonalGeodatbaseName & " completed")

 

 

                        Catch ex As Exception

                            Return False

                            LogDetails("Error trying to delete " & strfcname & " - " & ex.Message)

                        End Try

 

 

                        GP = New Geoprocessor

                        GP.OverwriteOutput = True

 

 

                        Try

                            LogDetails("Copying  " & strfcname & " to " & PersonalGeodatbaseName)

                            CopyFeatures = New ESRI.ArcGIS.DataManagementTools.CopyFeatures()

                            CopyFeatures.in_features = strfcname

                            CopyFeatures.out_feature_class = PersonalGeodatbaseName & "\Geographics_GDA94_srid5\" & strfcname

                            'CopyFeatures.config_keyword = ""

                            'CopyFeatures.spatial_grid_1 = 0

                            'CopyFeatures.spatial_grid_2 = 0

                            'CopyFeatures.spatial_grid_3 = 0

 

 

                            RunTool(GP, CopyFeatures, ITrack)

                            LogDetails("Copying of " & strfcname & " to " & PersonalGeodatbaseName & " completed")

                            copied = copied + 1

                        Catch ex As Exception

                            Return False

                            LogDetails("Error trying to copy " & strfcname & " - " & ex.Message)

                        End Try

 

 

I keep getting this error when ever I try using the Geoprocessor;

Error HRESULT E_FAIL has been returned from a call to a COM component.

 

I am using Visual Studio 2010 - .Net Framework 3.5 - AnyCPU - ArcGIS Desktop 10.2.1 (Product Version: 10.2.1.3497)

 

With the standard RunTool;

Public Sub RunTool(ByVal geoprocessor As Geoprocessor, ByVal process As IGPProcess, ByVal TC As ITrackCancel)

        ' Set the overwrite output option to true

        geoprocessor.OverwriteOutput = True

 

 

        Try

            geoprocessor.Execute(process, Nothing)

            ReturnMessages(geoprocessor)

 

 

        Catch err As Exception

            LogDetails("**Error Executing Geoprocessor for " & process.ToolboxName & " - " & err.Message)

            ReturnMessages(geoprocessor)

        End Try

    End Sub

 

 

    Public Sub ReturnMessages(ByVal gp As Geoprocessor)

        ' Print out the messages from tool executions

        Dim Count As Integer

        If gp.MessageCount > 0 Then

            For Count = 0 To gp.MessageCount - 1

                If Count = gp.MessageCount - 1 Then

                    LogDetails(gp.GetMessage(Count))

                End If

            Next

        End If

 

 

    End Sub
