Hello,
I want to get the selected features from a Layer.
Data:
tcKeyColumn= "INFOTEXT"
tcLayer= "flstkop3"
tcObjectIDs="FS3400400|FS3400500|"
This is my Code:
Public Function SelectMapFeatures(ByRef tcKeyColumn As String, ByRef tcLayer As String, ByRef tcObjectIDs As String, ByRef tcDataframe As String) As Boolean
Dim loMxDoc As IMxDocument = goApp.Document
Dim lomap As IMap = loMxDoc.FocusMap
Dim loActiveView As IActiveView
Dim loFeatureLayer As IFeatureLayer
Dim loFeatureSelection As IFeatureSelection
Dim loLayer As ILayer = lomap.Layer(0)
Dim loQueryFilter As IQueryFilter = New QueryFilter
Dim lcClause As String
Dim lcObjectID As String
Dim lcZWstring As String
Dim lcData As String
Dim lnSelektionAnzahl As Integer
Dim lnUebergabeObjektAnzahl As Integer
Dim lnNewFLSTIndex As Integer
Dim i As Integer
Dim j As Long
Dim llweiter As Boolean
Dim tlnew As Boolean
lcData = "x"
SelectMapFeatures = False
lnUebergabeObjektAnzahl = occurs(tcObjectIDs, "|")
ReDim gcObjId(lnUebergabeObjektAnzahl)
If Not tcDataframe = "" Then
If Not ActivateDataframe((tcDataframe)) Then
Exit Function
End If
End If
lomap.ClearSelection()
loActiveView = lomap
For i = 0 To lomap.LayerCount - 1
If TypeOf lomap.Layer(i) Is IGroupLayer Then
Call Get_GroupLayerName(loMxDoc, tcLayer, loLayer)
If Not loLayer Is Nothing Then
loFeatureLayer = loLayer
llweiter = True
Else
llweiter = False
End If
Else
If occurs(";" & UCase(tcLayer) & ";", ";" & UCase(GetLayerName(i)) & ";") Then
loFeatureLayer = lomap.Layer(i)
llweiter = True
Else
llweiter = False
End If
End If
If Not llweiter Then GoTo nexti
tlnew = True
lcClause = ""
For j = 1 To lnUebergabeObjektAnzahl
lcZWstring = token(tcObjectIDs, "|", j)
lcObjectID = token(lcZWstring, "(", 1)
lcClause = lcClause & Chr(91) & tcKeyColumn & Chr(93) & " = " & Chr(39) & lcObjectID & Chr(39) & " or "
Next j
lcClause = Left(lcClause, Len(lcClause) - 4)
loQueryFilter.WhereClause = lcClause
Dim pFSel As IFeatureSelection
pFSel = loLayer
loActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeoSelection, Nothing, Nothing)
If tlnew Then
Try
pFSel.SelectFeatures(loQueryFilter, esriSelectionResultEnum.esriSelectionResultNew, False)
Catch ex As Exception
MsgBox("Fehler " & vbCrLf & ex.Message)
End Try
Else
pFSel.SelectFeatures(loQueryFilter, esriSelectionResultEnum.esriSelectionResultAdd, False)
End If
tlnew = False
nexti:
Next i
loActiveView = Nothing
lomap = Nothing
loMxDoc = Nothing
End Function
When the layer where I select the features is in a Geodatabase it works good. If the layer is a shp-file I get the Error "Error HRESULT E_FAIL has been returned from a call to a COM component"
The original code was VB6 for ArcGIS 9.2, now it is VB.Net Express 2010 and ArcGis 10.2. With 9.2 it worked with Geodatabases and shp-Files.
May be I posted i lttle bit to much, but I tried a lot. Please, any Help. How can I get the selected features and get the values of a specified attribut when the features are in a shp-file?
