Error while exporting Numbered Vertices

AbdurRahman — Sun, 12 Dec 2021 02:17:25 GMT

Hi,

Earlier Query:

I am trying to run the code mentioned here in ArcGIS 10 but its giving an error at the below mentioned line:

  Set pFields = New esriCore.Fields

that compile error: user-defined type not defined.

New Query:

I tried to fix it and found that esriCore Library doesn't exist but instead the Fields Interface now belongs to GeoDatabase Library i.e. esriGeoDatabase.Fields. Now when I am running the code its giving an error of type mismatch at line mentioned below:

 Set pPC = pF.Shape

Help required
Thanks.

Hi,

The error type mismatch was due to the line

 Set pFLayer = pMxDoc.FocusMap.Layer(0)

as the selected layer was a point and the help for "IPointCollection" specifically mentions

that

Its used to access and manipulate the Points in Multipoints, Paths, Rings,

Polylines, Polygons, Triangles, TriangleFans, TriangleStrips, and MultiPatches

But still its not selecting any layer and returning an error that:

Item not found in this collection

In code mentioned below:

Public Sub a()
  Dim pMxDoc As IMxDocument
  Set pMxDoc = ThisDocument
  Dim pFLayer As IFeatureLayer
  Set pFLayer = pMxDoc.FocusMap.Layer(1)
  Dim pDS As IDataset
  Set pDS = pFLayer
  Dim pFWS As IFeatureWorkspace
  Set pFWS = pDS.Workspace


  Dim pFields As IFields
  Dim pFieldsEdit As IFieldsEdit
  Set pFields = New esriGeoDatabase.Fields
  Set pFieldsEdit = pFields

  Dim pField As IField
  Dim pFieldEdit As IFieldEdit


  Set pField = New esriGeoDatabase.Field
  Set pFieldEdit = pField
  With pFieldEdit
      .Length = 10
      .Name = "PolylineID"
      .Type = 1
  End With
  pFieldsEdit.AddField pField

  Set pField = New esriGeoDatabase.Field
  Set pFieldEdit = pField
  With pFieldEdit
      .Length = 10
      .Name = "VertexID"
      .Type = 1
  End With
  pFieldsEdit.AddField pField


  Set pField = New esriGeoDatabase.Field
  Set pFieldEdit = pField
  With pFieldEdit
      .Length = 20
      .Name = "X_Vertex"
      .Type = esriFieldTypeDouble
  End With
  pFieldsEdit.AddField pField

  Set pField = New esriGeoDatabase.Field
  Set pFieldEdit = pField
  With pFieldEdit
      .Length = 20
      .Name = "Y_Vertex"
      .Type = esriFieldTypeDouble
  End With
  pFieldsEdit.AddField pField


  Dim pTable As ITable
  
  Dim pTmpDS As IDataset
  Dim pEnumDS As IEnumDataset
  Dim pWS As IWorkspace
  Set pWS = pFWS
  Set pEnumDS = pWS.Datasets(esriDTTable)
  Set pTmpDS = pEnumDS.Next
  Do Until pTmpDS Is Nothing
    If pTmpDS.Name = "output" Then
        pTmpDS.Delete
        Exit Do
    End If
    Set pTmpDS = pEnumDS.Next
  Loop
  
  Set pTable = pFWS.CreateTable("output", pFields, Nothing, Nothing, "")
  
  Dim pFClass As IFeatureClass
  Set pFClass = pFLayer.FeatureClass
  Dim pFC As IFeatureCursor
  Set pFC = pFClass.Search(Nothing, False)
  Dim pF As IFeature
  Set pF = pFC.NextFeature
  Do Until pF Is Nothing
    Dim pPC As IPointCollection
    Set pPC = pF.Shape
    Dim i As Integer
    i = 1
    Dim x As Integer
    For x = 0 To pPC.PointCount - 1
        Dim pRow As IRow
        Set pRow = pTable.CreateRow
        pRow.Value(3) = pPC.Point(x).x
        pRow.Value(4) = pPC.Point(x).Y
        pRow.Value(2) = i
        pRow.Value(1) = pF.OID
        pRow.Store
        i = i + 1
    Next x
    Set pF = pFC.NextFeature
  Loop
   
End Sub

Please help as i'll be very thankful.
