I am working on migrating 9.3 Arc GIS Engine application to 10.1 Arc GIS Engine application. Everything is working good but at one of the following line(Dim pCalc2 As ICalculator = New ESRI.ArcGIS.GeoDatabaseUI.Calculator()) - I am getting the following message : Retrieving the COM class factory for component with CLSID {D676066E-38CA-429A-B846-DA7A8446C52D} failed due to the following error: 80040111. Any suggestions would be helpful. Thanks. ... View more

Hi, I am performing a query task for a layer whose display field is LINENAME. This filed LINENAME has attributes in mixed case lettera. For example one of the atrribute is "Stone Yard". As of now, only if I enter the attribute name as "Stone Yard" - which is as it is in the layer's non spatial data - it works, but with mix of upper and lower case like "STone YARD" or "STONE YARD" or "stone yard" doesn't work. Please let me know what updates I have to do for the below statement irrespective of what I enter - upper or lower case, or mix of upper and lower - the query must work : txtRailline is the text box for the user to enter the LINENAME attribute : query5.Where = "LINENAME ='" + txtRailline.Text.ToString(). + "'" Thanks for going through the message and providing your inputs. ...

Hello, I am performing an attribute query, and for that particular attribute - we want to zoom in to that  feature and draw a graphics layer. But although I added the graphic layer in the Mainpage.xaml - I am getting the following error at this particular line of code  : graphicsLayer1.Graphics.Add(selectedFeature); Error : Object reference not set to an instance of an object.
