See
How to use ArcGIS samples
for help on compiling, setting up the debugger, and 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.
Start Visual Studio, open the solution file, and build the project.
Run the application.
Browse to a Published Map File (PMF) from ArcMap to load.
Navigate to some features of interest.
Query the focus map for all visible features within the current map extent.
Loop through the features to display field values, and use the PanTo, ZoomTo, Flash, and Flicker buttons to identify each feature on the map.
