Question

I’m looking to have vista/win7 use Aero-style windows while XP users use normal window style (how does one get windows XP stlye and not win95 styles btw?)

The idea is something like this:

OSVERSIONINFOEX osvi;
osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
GetVersionEx((OSVERSIONINFO*)&osvi);
if (osvi.dwMajorVersion > 5) {
               #pragma comment(linker,"/manifestdependency:\"type='win32' "\
               "name='Microsoft.Windows.Common-Controls' "\
               "version='6.0.0.0' "\
               "processorArchitecture='x86' "\
               "publicKeyToken='6595b64144ccf1df' "\
               "language='*' "\
               "\"")
}

Now, the #pragma gets executed no matter if the if-statement is true or false, which I guess is just the way #pragma works. Surely there is some other way to get this to working (something like #ifndef #define … #endif I guess)

Cheers

You are mixing compile-time evaluation of pragma with run-time execution of code. Obviously this won’t work.

It’s possible to keep a manifest for the application in “PutYourProgramNameHere.exe.manifest” file. So if you need different manifests for XP and Vista/Win7, then you can install different manifest files when you install the application on the target computer. I.e. your installer checks OS version and installs matching manifest.
