Hi,
i'm trying to execute a merge tool in my ArcGIS Engine Application.
I'm not able to specify the Input FeatuterLayers, so that only selected Features are merged.
I tried:
...
Dim pParamInfo As ESRI.ArcGIS.esriSystem.IArray
pParamInfo = m_GPTool.ParameterInfo
Dim pParameter As IGPParameter
Dim pParamEdit As IGPParameterEdit
Dim pDataType As ESRI.ArcGIS.Geodatabase.IGPDataType
'Input
pParameter = pParamInfo.Element(0)
pParamEdit = pParameter
pDataType = pParameter.DataType
Dim sInputFeatures As String = "'InputLayer1','InputLayer2'"
pParamEdit.Value = pDataType.CreateValue(sInputFeatures)
'Output
pParameter = pParamInfo.Element(1)
pParamEdit = pParameter
pDataType = pParameter.DataType
pParamEdit.Value = pDataType.CreateValue("OutputLayer")
m_GPTool.Execute(pParamInfo, pTrackCancel, pGPEnvironmentManager, pGPMessages)
'with m_GPTool as IGPTool is the MergeTool
AND
...
Dim pMerge As ESRI.ArcGIS.DataManagementTools.Merge
pMerge = New ESRI.ArcGIS.DataManagementTools.Merge
pMerge.inputs = "'InputLayer1','InputLayer2'"
pMerge.output = "OutputLayer"
Dim GP As ESRI.ArcGIS.Geoprocessor.Geoprocessor = New ESRI.ArcGIS.Geoprocessor.Geoprocessor
GP.Execute(pMerge, Nothing)
I can't find a way to specify many FeatureLayers (as IFeatureLayer) and not FeatureLayerNames (as String) as InputParameter
This works with selected Features, but in_features is only one FeatureLayer:
Dim pClip As ESRI.ArcGIS.AnalysisTools.Clip
pClip = New ESRI.ArcGIS.AnalysisTools.Clip
pClip.in_features = SelectedFeatureLayer
But Merge needs a List of FeatureLayers.
Help apreciated!
