Using ArcObjects and VB.NET I have a routine that does several geoprocessing functions. These processes are built by ESRI to send messages to the ArcMap statusbar. That seems to over-ride my custom messages and progressbar. Is there a way to supress the geoprocessing messages sent to the statusbar? ... View more

ArcGIS and Pro: I code mostly in .NET and there are several instances where I need to use geoprocessing on geometry (IPoint, Ipolyline, IPolygon) but it seems almost none of the geoprocessing functions support this? Why? I have to resort to creating an InMemory feature class which requires more overhead if you are creating many geometry objects. I've also found that one or two geoprocessing functions will not work with an InMemory feature class. Please allow geoprocessing functions to take geometry as an input. ... View more

I am struggling to get an GP tool to work with Geometry.  What I do is create an IPolygon object through .NET code. All that works great except sometimes the results have slivers. So it looks like the Integrate tool could help me here. Again I have an IPolygon object and am not creating any feature classes on disk. I will draw the polygon to the screen and that is it. So I try this: 'use the Integrate tool to get rid of slivers Dim gp As Geoprocessor = New Geoprocessor gp.OverwriteOutput = True gp.AddOutputsToMap = False Dim intgGeom As Integrate = New Integrate intgGeom.in_features = pClonePolygon 'the input polygon intgGeom.cluster_tolerance = "2 Meters" 'set the XYTolerance to 2 Meters gp.Execute(intgGeom, Nothing) No cigar. I get this exception: A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in ESRI.ArcGIS.Geoprocessor.dll System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.

ArcGIS 10.1 with VB2010 I am using the GxDialog to get the users option to save a feature class. The target can be a shapefile, geodatabase, or Dataset inside a geodatabase. I can’t wrap my head around how I am supposed to parse the Workspace, FeatureDataset, and FeatureClass name to use in creating the feature class.   So far I have               'setup the save dialog             Dim pGxDialog As IGxDialog = New GxDialog             Dim pGxObjFilterSh As IGxObjectFilter = New GxFilterShapefiles          'shapefiles             Dim pGxObjFilterPg As IGxObjectFilter = New GxFilterPGDBFeatureClasses  'personal geodb (Access db)             'Dim pGxObjFilterFg As IGxObjectFilter = New GxFilterFGDBFeatureClasses  'file geodb (ESRI db)             Dim pGxObjectFilterCollection As IGxObjectFilterCollection = CType(pGxDialog, IGxObjectFilterCollection)             pGxObjectFilterCollection.AddFilter(pGxObjFilterSh, True)             pGxObjectFilterCollection.AddFilter(pGxObjFilterPg, False) 'this one actually contains both file and personal geodb feature classes             'pGxObjectFilterCollection.AddFilter(pGxObjFilterFg, False)               'get the users selection (it can be a shapefile or a geodb).

In VB2010 I am using the IQueryFilter interface to hit a shapefile and get back some records. It works great but am having trouble figuring out how to get results back in an order as input by the user. They input airports in a listbox and I take that and create a where clause out of it. By default the recordset returned is in alphabetical order which will not work here as the user needs the results back in the order they input.             Dim pQryFltr As IQueryFilter = New QueryFilter             pQryFltr.WhereClause = "APT LIKE 'DFW' OR APT LIKE 'STL' OR APT LIKE 'ORD'" results come back as DFW ORD STL I am trying to figure out how I can return the results in an order that is equivalent to how the user input the data. Is that even possible? ~AGP ... View more
