Microsoft Win32 to Microsoft .NET Framework API Map

.NET Development (General) Technical Articles
 
  Microsoft .NET Framework and Microsoft Visual Studio User Education Teams
Microsoft Corporation

January 2004

Applies to:
    Microsoft® .NET Framework version 1.0 or 1.1
    Microsoft Visual Studio® .NET
    Microsoft Win32® functions

Summary: This article identifies the Microsoft .NET Framework version 1.0 or 1.1 APIs that provide similar functionality to Microsoft Win32 functions. One or more relevant .NET Framework APIs are shown for each Win32 function listed. The intended audience for this article is experienced Win32 developers who are creating applications or libraries based on the Microsoft .NET Framework, but anyone looking for a managed counterpart for a Win32 function could find this document useful. (85 printed pages)

In this article, the Microsoft® Win32® functions are organized by category. Each Win32 function that is listed belongs to only one category, and each category is presented in its own table. An alphabetical list of the Win32 categories is provided, as well as a hierarchical list. To locate a Win32 function, select the appropriate category from one of the category lists or search the article for the name of the function. If you do not find the Win32 function that you are seeking, it means that no equivalent .NET Framework API exists in the .NET Framework version 1.0 or 1.1 or that the Win32 function and the relevant .NET Framework API were inadvertently omitted from the list.

If you believe that a Win32 function and the relevant .NET Framework API have been omitted from this article, please let us know by using the feedback link. For more information on the APIs listed in this article, see the Platform SDK documentation or the .NET Framework SDK documentation in the MSDN® library.
