I need an arcmap extension written in VC++ preferably or VB. It needs to add a toolbar item that when selected, on left mouse, if a specific shape file is loaded will go to the nearest point on that layer and read the data fields (string, int, and/or double), and then make a COM call using the data from the point feature. Example code should use one string, one double, and one int field. All errors should be caught using try catch blocks. Code should be written favoring ease of understanding over all other condiserations. This is a proof of concept project and there is a good chance of follow on work.
