I finally find a solution to my problem. Thanks to all

Hi all I want to cut a polygon by many polylines but i don't know how to do it. I can cut polygon to 2 parts ( left and right ) using this code ESRI.ArcGIS.Geometry.ITopologicalOperator4 topologicalOperator4 = polygon as ESRI.ArcGIS.Geometry.ITopologicalOperator4; ESRI.ArcGIS.Geometry.IGeometryCollection geometryCollection = topologicalOperator4.Cut2(polyline); But how to cut by many polylines. Waitting for your help.

I used to use this code but I can't union 2 adjacent polygons, result return only one polygon (polygon 1 to union ). Two polygons don't intersect , just have a common segment. How can I fix that?

I have some selected feature as Polygon in SDE geo database show in map control. They are side-by-side features but now I want to merge them into one by code . How can I do this, anyone has any example code ? I use ArcGIS engine 9.3 and C# thank you Cuongdx

Of couse I will try my best to help another people to find solution. I don't know how to mark thread is answered to close.Can you show me how to do this?

Great.It work for me, thanks you weif4314 .

I use this code to find intersect of 2 polygon void CreatePolylineFromExistingGeometries(ESRI.ArcGIS.Geometry.IPolygon pPolygon1, ESRI.ArcGIS.Geometry.IPolygon pPolygon2) { //Build a new polyline by intersecting two existing polygons. ESRI.ArcGIS.Geometry.ITopologicalOperator2 pTopoOp2 = pPolygon1 as ITopologicalOperator2; //Simplify. pTopoOp2.IsKnownSimple_2 = false; pTopoOp2.Simplify(); ESRI.ArcGIS.Geometry.IPolyline pPoly = pTopoOp2.Intersect(pPolygon2, ESRI.ArcGIS.Geometry.esriGeometryDimension.esriGeometry1Dimension) as IPolyline; //pPoly is the new generated polyline. } but when i check pPoly ( new polyline generated) then the properties IsEmpty of pPoly is true so i can't show pPoly in map. When i change esriGeometry1Dimension to esriGeometry2Dimension and return IPolygon then i can show Polygon intersect of 2 polygon. But i want to use polyline more than polygon intersect. So how to fix this problem?

I use arcgis engine 9.3 and C#, i want to query geodatabase by a rectangle and get all polygon or segment within rectangle.So i intend to query all polygon and use ITopologicalOperator::Intersect to get segment within rectangle.Is it the best way?Do you have any code about it?

Thank you weif4314 , although i don't really know how to do but i will try by that way.Can you support me?

But I want to get a part of segment in shape, not all segment.How can i do it?

i have a problem.I can set character spacing to a IElement as ITexElement like : TextSymbolClass pTextSymbol = new TextSymbolClass(); pTextSymbol.CharacterSpacing = 10 ; //etc ((ITextElement)firstElement).Symbol= pTextSymbol; //firstElement is a Element in map Now i want to get value of CharacterSpacing when i focus to a ITextElement in Map.But when i used this code below, some thing happen and it break from function and have no exception. TextSymbolClass pTextSymbol2 = new TextSymbolClass(); pTextSymbol2 = (TextSymbolClass)((ITextElement)firstElement).Symbol; //break from here value=pTextSymbol2.CharacterSpacing ; So, how can I get the CharacterSpacing value of a Element,can you show me another way to get it.I'm using Arcgis engine 9.3, C# .Thank you so much.

Hi every one, i have a issue.I have a feature class type of polygon in SDE geodatabase, and i want to query by a shape and get all segment of polygon within shape (only segment, not all polygon) .How can i do it.I use arcgis engine 9.3 and C#. Thanks and Regard. Cuongdx
