In MapSuite Explorer Desktop Edition 3.x, when I added a shapefile, I was prompted to build an index of some type. I believe this resulted in the creation of .sbn and .sbx files for the shapefile. In MapSuite Explorer WPF Desktop Edition 4.x, I am no longer prompted to build the index. (I had deleted the .sbn and .sbx files created by the previous version). My questions are:
1) What are the .sbn and .sbx files that were created by the previous Desktop Edition when adding a shapefile? (I assume these are different than spatial index files).
2) Are these required or do they speed up draw time for a ShapeFileFeatureLayer in the Wpf Desktop Edition?
3) If so, how do I create them with code?
Thank you, Rod
