SUMMARY
Because the architecture of Windows 95 and later and Windows NT is 32-bit, there are several differences in the application programming interface (API) from the 16-bit API of Windows 3.x. This article shows you how to convert code that contains 16-bit API calls to 32-bit API calls so that the code will run successfully in a 32-bit operating environment. This article discusses the following topics:
 * Why 16-bit API calls do not work in a 32-bit operating environment
 * Tips on how to make the conversion process easier
 * List of converted declaration statements for common API functions that you can copy into your modules



Why 16-bit API Calls Do Not Work in a 32-bit Operating Environment
You cannot use a 16-bit API call in the Windows 95 and later or Windows NT 32-bit operating environment for the following reasons:  The API library names (dll) are different, for example:  Parameter data types are often different, for example:

NOTE: This is not a complete list. You should watch closely for different parameter data types when you convert code that makes an API call or supplies parameters to an API call.  API function names are case-sensitive. This differs from the 16-bit API, which is not case-sensitive. For example, in a 16-bit API call, the following statements are equivalent: Declare Function GetVersion Lib "KERNEL" as Long Declare Function gEtVeRsIoN Lib "KERNEL" as Long   However, when converted to a 32-bit API, the following statements are not equivalent because the function names are case-sensitive: Declare Function GetVersion Lib "KERNEL32" as Long Declare Function gEtVeRsIoN Lib "KERNEL32" as Long  Some API functions have different versions to accommodate ANSI and UniCode strings. If an API listed in this article is limited to use under a specific operating system in 32-bit, it will be noted with the API function.</ul>

Tips on How to Make the Conversion Process Easier
You can reduce the work involved with converting your existing code by adopting these practices:
 * When you declare an API procedure, use an alias for the procedure name. The alias must be unique from the function name. If it is not, the alias will be deleted automatically.
 * When you declare the data type returned by the function or the data type of parameters passed to the function, use an As clause rather than the type declaration characters (%, $, and so on).
