   ::UpdateLayeredWindow, apparently not declared
  HiIve been doing some simple win32 stuff, using regions. I had some problems (have rather) and was looking for answers when i came across UpdateLayeredWindow() and SetLayeredWindowAttributes().So i decided i wanted to try using UpdateLayeredWindow()..declared in winuser.h, include windows.h - checkimport library user32.lib - checkIm not manually importing user32.lib, im suspecting dev-c++ of being nice to me, because it works for everything else.I still get "'::UpdateLayeredWindow()' has not been declared" when i try to compile.. Ive rummaged around MSDN a fair bit, and read what appeared to be a good introduction to this piece of API, but didnt really find anything there that could hint to a soloution.Im using dev-c++ v4.9.9.2, sporting the mingW v3.4.2 compiler.If anyone can help me whith this its greatly appreciated /sok   
  I think you might have to define your windows version, the layered stuff is win2k+ only IIRC. Try #defining _WIN32_WINNT 0x0501 before you #include "windows.h".   ;  Because those are newer API functions they are only supported in Windows 2000 and above, so you have to #define certain macros:#define _WIN32_WINNT 0x0500#define WINVER 0x0500Look here for more information   ;  My link didnt work right, http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winprog/winprog/using_the_windows_headers.asp should have the all the information you need.   ;  Thanks!This ofcourse revelas more problems, but thats how i learn :)
