All of the examples I can find only have this property set to a .shp file.

I do have another question though. Is there a way to pass a feature class to the Union .in_features property, but tell it to only use the selected features? Currently I am exporting the selected features to a new feature class using the IExportOperation interface. That works but it shows the progress box which i don't want the users to see. If this is the only way to do it, is there a way to stop the progress box from showing?</P></BODY></HTML> Fri, 20 May 2016 01:37:49 GMT https://community.esri.com/t5/arcobjects-sdk-questions/esri-arcgis-analysistools-union-question/m-p/312253#M8144 GlynnFlowerday 2016-05-20T01:37:49Z Re: ESRI.ArcGIS.AnalysisTools.Union question https://community.esri.com/t5/arcobjects-sdk-questions/esri-arcgis-analysistools-union-question/m-p/312254#M8145 <HTML><HEAD></HEAD><BODY><P>Instead of using the feature class as the input, use a feature layer. If a feature layer contains selected features, the Union will only occur with the features that have been selected, not all of them.</P><P></P><P>This is an example of that done manually using the Union tool. The hashed circles are the result of the union between two feature layers with one selected circle each.</P><P></P><P><IMG __jive_id="201810" alt="union.png" class="image-1 jive-image" src="https://community.esri.com/legacyfs/online/201810_union.png" style="width: 620px; height: 440px;" /></P></BODY></HTML> Mon, 23 May 2016 18:22:11 GMT https://community.esri.com/t5/arcobjects-sdk-questions/esri-arcgis-analysistools-union-question/m-p/312254#M8145 KenBuja 2016-05-23T18:22:11Z Re: ESRI.ArcGIS.AnalysisTools.Union question https://community.esri.com/t5/arcobjects-sdk-questions/esri-arcgis-analysistools-union-question/m-p/312255#M8146 <HTML><HEAD></HEAD><BODY><P>Great Ken, that works for me.
