Hi Somthing like this should do it: IPointCollection pPoly = new PolygonClass(); object Missing = Type.Missing; pPoly.AddPoint(P1, ref Missing, ref Missing); pPoly.AddPoint(P2, ref Missing, ref Missing); pPoly.AddPoint(P3, ref Missing, ref Missing); ((IPolygon)pPoly).Close(); Have Fun Mody

Hi Vince Thanks for the answer. As you said the problem is the complexity of the polygons and not their number. Most polygons have many islands and not holes (think about Greece). The only operation needed is really to select polygons by point (there might be many polygon in one point) and display. It all stored in st_geometry format. We did some tuning on the spatial index. We can understand and accept slow performance, but we would like to get a result from the query. Any specific tuning you can think about? Thanks Mody

Hello all We have an unusual polygon layer in ArcSDE that does not behave well. It has only 200k-300k polygons but most of them has 100-200 parts and each part can include up to 5000 vertexes. In some extents you cannot identify or select the polygons. When you decrease the number of total polygons (using definition query) the same polygons can be selected or identified. It looks like we are getting to some limitation of ArcSDE. There is no error messages on the screen or in log files. We are using ArcSDE 10 on Oracle11g. Does anybody run into this problem? Is there any tuning (Oracle, server config) that we can try to do? Thanks Mody

Hello all When you work with Desktop you can create bookmark files (using bookmark manager) to share bookmarks with others. Is there any way to access this file in code? The IMapBookmark does not have any Load/Save methods. We think that it might be MyPlaceCollection class but we are not sure. Did anybody ever tried to do it? Thanks Mody

When you open feature class properties in general tab it is written in the version group on the bottom of the page. Mody

Hi Faisal If you are working in version environment the records are not added to the base table until you compress you geodatabase. Even then if anybody is looking on the layers the records from the delta tables (A & D) might not be written into base. You can check the �??move to base�?� checkbox when you register the layer as version or work without versioning at all. Have Fun Mody

Hi All Alias can be at the MXD level but can be at the GeoDatabase level too. I do not think it is possible to drop them from geodatabase but the easier way will be to calculate them to be the same as the field name. I think this is the default when you create a new field too. Have Fun Mody

Hi Timothy Will it just work in version 10? Is any projection (even one that does not exists in ESRI predefine projections) will be recognize by desktop because it uses GDAL? Thanks Mody

Hi Dave Try to check spatial reference on both geometries �?? it should be the same. Have Fun Mody

Hi Deyala The easiest way is to take the average value from the statistics and multiply it by the number of pixels. Have Fun Mody

We have a strange problem with Mosaic dataset. I would like to know if anybody run into it. We have two different mosaics that are partially overlap and does not have overviews. We build a new Mosaic and use the Add Rasters with the �??table�?� option to import the footprint of the two mosaics into the new mosaic. Then we build the overviews for the new mosaic with the default options. The new mosaic is extremely slow when we in the overview level (over 15 sec for pan) but very quick when we zoom in into real rasters (less than a sec for pan). If we build overviews for the original two mosaics they works fine. All 3 mosaics are in the same FGDB and there overviews are on the same disk location. If I try to load the overviews of the new mosaic as a raster from disk they show with no problem. Does anybody run into this problem? Thanks Mody

Hi Nick When I say "access" I mean you can read and query the tables but not necessary update them. If you do not have ArcSDE you can see oracle tables is using OLEDB. If ESRI will drop the support for mdb file you can still see them using OLEDB (but update them using Microsoft Access). If you have, for example, Sybase database you can see it using OLEDB. The metadata for ArcSDE is tables inside the SDE schema. When you use the ArcSDE connections they are not visible. If you use OLEDB connection you can see them just like any other table. Mody

Hi Nick I think the main use of OLEDB is to access databases that does not have a direct connect in ArcGIS. OLEDB connections exists for many types of data that ArcGIS can not read directly. The only reason to use OLEDB for access or Oracle database that has SDE is to look into the metadata files �?? you should not update these so the read only access is not a limitation. Have Fun Mody

Hi Rick The FeatureClassToGeodatabase_conversion get a comma delimited list of feature classes. You should build this list from the ListFeatureClasses Try something like this: s = "[ " for fc in fcList: print fc s = s + '"' + fc + '"' + " ," # delete last comma and close brackets s = s[0:len(s) - 1] + " ]" have fun Mody

Hi I think it should be: m_dynamicMap = (IDynamicMap)m_mapcontrol.Map; Have Fun Mody
