Windows Structs

DataFlex uses numerous structures defined in the Windows operating system API. These structs are used internally in the packages to access the Windows API.

Learning about Windows Structures

We do not expect developers to need to do this themselves. If developers do wish to access the API, they can use these structs already defined in the DataFlex packages. In such a case, we expect that the developers will use the Microsoft Developer Network (MSDN) to learn how to use the API and these types.

The structs below are all defined in tWinStructs.pkg. Developers can view this file or the documentation below, find the struct they want, and refer to the MSDN documentation to learn how it works.

Adding Your Own Windows Structs

We will add more struct definitions in future revisions as we need them. It is not our intent and it is not feasible to create definitions for all Windows types.

The naming convention used by the structs in the DataFlex packages is tWinXxxx. If you wish to use additional Windows structs that are not defined in tWinStructs.pkg, you should use a different naming convention to avoid naming collisions.
