C++ DEVQUERY Sample Application
This C sample application is a Win32 console application. It illustrates
how to use the PICOTEST IOUtils COM. A Win32 console application is a
Win32 application which uses text-based input and output, not a
graphical interface. This allows you to quickly create a Win32
application by using simple input and output functions.
Creating the Application
Create a new Visual C++ project as follows:
1. Create a new Win32 Console Application project, calling the project
DEVQUERY.
2. Specify that this project will be a simple application in the last
AppWizard step.
LISTING C.3. THE DEVQUERY FUNCTION.
