Manage snap agents

Purpose
This sample demonstrates how to programmatically add, remove, and turn on IEngineSnapAgent and IEngineFeatureSnapAgent. These changes are made to IEngineSnapEnvironment and are reflected in the Editor's Snap Settings dialog box and the custom Snap Editor form that is supplied with this sample.

How to use

See How to use ArcGIS samples for help on running the sample. If the sample has associated data, you will find that the sample's zip file includes a "data" folder alongside the language folders. However, you will need to update the sample to point to the location of the data once you have extracted all the files.

  1. Start the sample application. The ushigh.shp shapefile from the sample data is loaded into the Map control.
  2. Start an edit session using the Editor menu on the toolbar.
  3. Click the Snapping Dialog command to start the Snapping Dialog.
  4. Use the controls on the Snapping Dialog to modify the snapping environment. The changes made by the Snapping Dialog are reflected in the Snapping control on the Editor menu.
