Glad it's working...To open an edit session on a layer not loaded in ArcMap you can open the workspace using IWorkspaceFactory.OpenFromFile and IWorkspaceEdit. Here is an old sample that opens a personal geodatabase which will work in ArcMap, ArcCatalog, etc.: Dim pFClass As IFeatureClass
Dim pEnumDS As IEnumDataset
Dim pDS As IDataset
Dim pWS As IWorkspace
Dim pWSE As IWorkspaceEdit
Dim pWSF As IWorkspaceFactory
Set pWSF = New AccessWorkspaceFactory
Set pWS = pWSF.OpenFromFile("C:\TestData\TestData.mdb", 0)
Set pWSE = pWS
Set pEnumDS = pWS.Datasets(esriDTAny)
Set pDS = pEnumDS.Next
Do Until pDS Is Nothing
If pDS.Name = "TestLayer1" Then
Set pFClass = pDS
Exit Do
End If
Set pDS = pEnumDS.Next
Loop
If Not pFClass Is Nothing Then
pWSE.StartEditing False
pWSE.StartEditOperation
Dim pFCur As IFeatureCursor
Dim pFeat As IFeature
Set pFCur = pFClass.Search(Nothing, False)
Set pFeat = pFCur.NextFeature
Do Until pFeat Is Nothing
''Do something with feature....
Set pFeat = pFCur.NextFeature
Loop
pWSE.StopEditOperation
pWSE.StopEditing True
End If
Thanks Jeff, that's the way: start an edit session.
'*** edit session running ***
If TypeOf pElement.Geometry Is IPolyline Then
Dim pPointCol As IPointCollection
Set pPointCol = New Polyline
Set pPointCol = pElement.Geometry
'Replace textPath here ......
' Just keep start- and endpoint
Dim pNewPolyline As IPolyline
Set pNewPolyline = New Polyline
pNewPolyline.fromPoint = pPointCol.Point(0)
pNewPolyline.toPoint = pPointCol.Point(pPointCol.PointCount - 1)
pElement.Geometry = pNewPolyline
pAnnoFeat.Annotation = pElement
pFeatureCursor.UpdateFeature pFeature
End If
One more question: is it possible to start an edit session programatically without having the involved featureclass loaded in the table of contents?
