ChangeDisplaySettingsEx / PocketPC 2002 and 2003

Hi to all!

I'm trying to write a function to know actual screen orientation on
pocketpc.

I saw on MSDN that i can fetch related info with this code:

DEVMODE devmode = {0};
devmode.dmSize = sizeof(DEVMODE);
devmode.dmFields = DM_DISPLAYORIENTATION;
ChangeDisplaySettingsEx(NULL, &devmode, 0, CDS_TEST, NULL);

That's run fine if i compile the code with EVC++4 + ppc2003sdk for
pocketpc with windows mobile 2003 or later; but what about ppc2002?

There's a way to keep same executable, compiled with evc++3, that can
tell me screen orientation on ppc2002,2003/2003se/2005 and so on?

I know that there isn't screen orientation on ppc2002, but this
function in that case could give me "n/a" or "normal orientation" or
similar...

To be short:
- I should use ChangeDisplaySettingsEx in order to get screen
orientation
- ChangeDisplaySettingsEx is not available unless i use evc++4 with
ppc2003 sdk
- If i compile it with evc++4 it won't run on ppc2002

Do you think could be a solution for this? (without using 2
executables!)
:)

Thanks in advance for your patience!

Daniele.

Dynamically load the function (GetProcAddress) and if it's not available,
then don't call it (meaning you're likely on PPC02).
