Vermont Views for Windows uses a 32-bit library; therefore, any existing 16-bit DOS applications must be converted to 32-bit applications before they can be developed as Windows applications.
When working in the Vermont Views for Windows Programming Environment, be aware of the following:
Because the Vermont Views for Windows library calls the standard Windows software development kit (SDK) API directly, you do not need additional API packages or third-party products, such as Microsoft Foundation Classes (MFC) or Borland Object Windows Library(OWL).
The Vermont Views for Windows library uses the compiler define of __WIN32__ for conditional compilation of the Vermont Views header files and the application. You must set this, either on the compiler command line by adding "-D__WIN32__", or from within the interactive development environment (IDE). (For more information, refer to the documentation for your compiler.)
Vermont Views for Windows uses the new three-dimensional controls available with 32-bit Windows and Windows NT; therefore, you need to link your application with the comctl32.lib library supplied with your compiler.
