Hi all, first let me describe my situation as there may be a better way of handling it.
I am working with ArcEngine 9.3.1 with C#. I have a search form that allows the user to query for data in any field and
display the results. I have a second form that can be displayed at that point to display a colored layer over the results.
I want to be able to color in the results with different colors based on sub queries.
I thought of using a uniquevaluerenderer for this as it would give me the layer layout that I need (color coded categories), but unfortunately with it needing unique values, I can't use wildcards to grab multiple polygons.
I decided then that I would create my own featureclass on-the-fly and populate it with my results and adding a field
to indicate what records belonged to what color group, that way I could use the uniquevaluerenderer.
An Example:
I query for all parcel numbers that start 074
With those results, I would like to color code them in the following way:
074A = Red
074B = Yellow
074C = Green
etc
I dug around and finally figured out how to add a featureclass and can populate it the way I want, but now the problem is...I can't delete it. I really don't want to leave my featureclass in the geodatabase after the query results have been displayed.
When I try to delete the featureclass (using DeleteByName() from IFeatureWorkspaceManage), I get the error message
"The application is not licensed to perform this operation". Why would I be licensed to create but not to delete?
Any help on this would be much appreciated
