Creating a Win32 Windows Application using Win32 Application Wizard

- Click New Project... in Microsoft Visual Studio 11 Developer Preview

- Select Template of Visual C++ Win32, Win32 Project, enter Name of the project, ex. Win32Project1, and click Enter.


- Walk through the steps of Application Wizard, by clicking of Next.


- Review and accept the default setting by clicking of Finish.


- The Application Wizard will generate the default Win32 Project for you.


- Where Win32Project1.cpp is the main application source file.

// Win32Project1.cpp : Defines the entry point for the application.
