[Dev-C++] What does _WIN32_IE define ?

[Peter S. <p.s...@ut...>]

Hi,

in some system headers, for instance commctrl.h and 
prsht.h are a lot of Constants commented out with
_WIN32_IE . What does the value of  _WIN32_IE
mean and are there any drawbacks if I define it ?

Is there an official  way to define such constants 
globally in the IDE ?

tia, Peter

Hi Peter,
 
Apparently it defines what version of Internet Explorer is in the system.  Read Using the Windows Headers from the MSDN site.  It's about 2/3 down the page.

Alfred, thanks for info ! I didn't imagine that
system constants may be defined with
respect to an application. Well, - it is MS ! :-))

[Per W. <pw...@ia...>]

You are not defining system constants in the application. What you are
doing is specifying which minimum version of Win32 OS and IE that are
required for running your application.

By increasing the requirements, the include files will allow you to access
more advanced features, but of course your application will not run on
older operating systems (such as Win95, Win98, NT 3.51 or similar) or the
application will require DLL files installed with recent IE versions to be
able to display new child controls or similar.

This is similar to building on a Linux machine. There it is possible
to specify if extra GNU extensions should be allowed - features not
available in a POSIX system.
