What exactly does it do again?

Can anyone, please, tell me what these manifests are, where do they fit in my application binaries, why is one needed to get the pretty windows 7 buttons and how to use them with DMD?

Just FYI, you don't actually *need* to include manifests in your executable, if you know another DLL already has them.

Here's a hack to show what I mean, for enabling visual styles:

void enableVisualStyles()
{
TCHAR[MAX_PATH] dir;
dir[GetSystemDirectory(dir.ptr, dir.length)] = '\0';
enum
{
ACTCTX_FLAG_ASSEMBLY_DIRECTORY_VALID = 0x00000004,
ACTCTX_FLAG_RESOURCE_NAME_VALID = 0x00000008,
ACTCTX_FLAG_SET_PROCESS_DEFAULT = 0x00000010,
}
auto actCtx = ACTCTX(ACTCTX.sizeof,
ACTCTX_FLAG_RESOURCE_NAME_VALID |
ACTCTX_FLAG_SET_PROCESS_DEFAULT |
ACTCTX_FLAG_ASSEMBLY_DIRECTORY_VALID,
"shell32.dll", PROCESSOR_ARCHITECTURE_INTEL,
0, dir.ptr, MAKEINTRESOURCE(124), null, null);
auto hActCtx = CreateActCtx(actCtx);
assert(hActCtx != INVALID_HANDLE_VALUE);
ULONG_PTR ulpActivationCookie;
BOOL success = ActivateActCtx(hActCtx, ulpActivationCookie);
assert(success);
}

Basically, since shell32.dll already has our manifest, I can just call this function instead. :-)
