Hi,
Has anyone tried this before or have ideas about how to solve the problem ?
What I want to do:

mi/example_creating_a_wmi_application.asp)

What I tried:
Installed Dev-C++ 4.9.9.2 on my Windows 2000 machine and tried to
compile the program - the compiler complained about not being able to
find comdef.h. So downloaded the Windows SDK from MSDN and installed
it (From the ISO image 5.2.3790.1830.15.PlatformSDK_Svr2003SP1_rtm.img
after burning a CD with it). Added the SDK include and lib directories
in the project options. Now the top of the compile log looks like this
- the compiler gives me 470 errors !

I did a Google search for ui64 and came across this in the change log
for lcc-win32 (http://www.q-software-solutions.de/products/lcc-win32/change=
log.shtml):
The compiler now recognizes I64 and UI64 as suffixes equivalent to LL and
ULL to remain compatible with Microsoft notation.
No warnings were given when a long long constant overflowed. Fixed.
Might the compiler in Dev-C++ need changes along these lines ? Or is
there some simple solution ?
