Hi,
I would like to know how we can for BCB to only include 1 instance of
*.h file, in case it is declared in several *.cpp or other *.h files.
i include only once the file "shlobj.h" within my class.
However, when i use my class in some other class, BCB informs me that in
the file "shlobj.h", there are multiple declaration for several types...
like [C++ Error] shobjidl.h(2372): E2238 Multiple declaration for
'FOLDERSETTINGS'
But i'm sure that i only included once this *.h file.
and everything is under #ifndef, #define and #endif...
thx,
AL.

place. It should only declare types, etc. Otherwise you'll get
multiple definitions.
If a header file can only be included once in a whole project, it's
rather useless.
If you'd like help fixing the problem with your header, please post
some actual code (a small example (<= 50 LOC) that accurately
demonstrates the problem.) Thanks.

Try putting NO_WIN32_LEAN_AND_MEAN in the conditional defines.

(especially third-party headers) use header guards, though.
in order to address that particular issue.
