Does your book cover using VB forms in a C++ project? Or, is it better to
call C++ code from within a VB project? I'm interested in how I might use
a VB form as a user interface for data input, with command buttons that will
trigger the execution of C++ code.

A simple example I have in mind is a VB form with two text boxes. The first
text box will accept a first name and the second a last name. How can I
call C++ code to display the contents entered in each text box after a command
button is clicked? Thanks.
