高亮顯示被選中feature,并可控制非選擇feature顯示或隱藏...

使用IQueryFilter過濾選擇集，利用IFeatureSelection.SelectionSymbol設置被選擇要素的外觀。

IFeatureLayerDefinition.DefinitionExpression用于控制圖層上的要素顯示狀態。

Private Sub SearchSlope()Sub SearchSlope(pLayer As ILayer, strSlopes As String, chkfilterValue As Boolean)

Dim pFeaturelayer As IFeatureLayer

Set pFeaturelayer = pLayer

Dim pFeatureSelection As IFeatureSelection

Set pFeatureSelection = pFeaturelayer

Dim pDefFeatLayer As IFeatureLayerDefinition

Set pDefFeatLayer = pFeaturelayer

If chkfilterValue = True Then

pDefFeatLayer.DefinitionExpression = "SLOPENO IN (" & strSlopes & ")"

Else

pDefFeatLayer.DefinitionExpression = ""

End If

Dim pFilter As IQueryFilter

Set pFilter = New QueryFilter

pFilter.WhereClause = "SLOPENO IN (" & strSlopes & ")"

Dim pFillSym As ISimpleFillSymbol

Set pFillSym = New SimpleFillSymbol

pFillSym.Style = esriSFSDiagonalCross

pFeatureSelection.SetSelectionSymbol = True

Set pFeatureSelection.SelectionSymbol = pFillSym

pFeatureSelection.SelectFeatures pFilter, esriSelectionResultNew, False

End Sub
