Generate include files for Windows constants

The included program allows the generation of include files containing pre-processor definition for all of the constants within any type library. Type libraries may either be specific type library files (.olb,.tlb) or can be contained within .exe,.dll or .ocx files.
I typically need to know constants when working with COM or ActiveX objects in the 4GL. Often, the documentation for such objects refers to various property values by the name of the constant. This is because most documentation is geared towards development environments where the constant values will automatically be made available to the developer. Such is not the case for Progress.

The Win32 API contains many constants.
winconst.zip contains a list of more than 14000 P4GL preprocessor definitions and a utility that helps to find dependencies.
For example, the constant WVR_REDRAW is defined as (WVR_HREDRAW | WVR_VREDRAW).

When you search for WVR_REDRAW in winconst.exe it will return

&GLOBAL-DEFINE WVR_VREDRAW 512
&GLOBAL-DEFINE WVR_HREDRAW 256
&GLOBAL-DEFINE WVR_REDRAW  ({&WVR_HREDRAW} + {&WVR_VREDRAW})

winconst.zip is freeware. So feel free to download it :-)
