ATL Program or Control Source and Header Files

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at ATL Program or Control Source and Header Files.

The following files are created when you create an ATL project in Visual Studio, depending on the options you select for the project you create.

All of these files are located in the Projname directory, and in either the Header Files (.h files) folder or Source Files (.cpp files) folder in Solution Explorer.
