Porting Applications

The following sections describe general areas of code you need to modify when porting a 16-bit application to Win32. These areas include the following:

• Window procedure declarations
  
  
• Near and far type declarations
  
  
• Data types
  
  
• Messages
  
  
• Calls to API functions
  
  
• WinMain function

If your application uses advanced techniques, such as manipulating the WIN.INI file, focus, and mouse capture, you may need to consult the section Special Considerations for Advanced Applications.
