How do I enable visual styles?

[Jack]

if someone happens to be looking to do that in the future: I 
didn't find a way to do this with a linker but managed to find a 
way to do this with code only. The code goes like this:

// source: https://stackoverflow.com/a/10444161/800123
#include <windows.h>

// NOTE: It is recommended that you delay-load ComCtl32.dll 
(/DelayLoad:ComCtl32.dll)
// and that you ensure this code runs before GUI components are 
loaded.
// Otherwise, you may get weird issues, like black backgrounds in 
icons in image lists.
ULONG_PTR EnableVisualStyles(VOID)
{
     TCHAR dir[MAX_PATH];
     ULONG_PTR ulpActivationCookie = FALSE;
     ACTCTX actCtx =
     {
         sizeof(actCtx),
         ACTCTX_FLAG_RESOURCE_NAME_VALID
             | ACTCTX_FLAG_SET_PROCESS_DEFAULT
             | ACTCTX_FLAG_ASSEMBLY_DIRECTORY_VALID,
         TEXT("shell32.dll"), 0, 0, dir, (LPCTSTR)124
     };
     UINT cch = GetSystemDirectory(dir, sizeof(dir) / 
sizeof(*dir));
     if (cch >= sizeof(dir) / sizeof(*dir)) { return FALSE; 
/*shouldn't happen*/ }
     dir[cch] = TEXT('\0');
     ActivateActCtx(CreateActCtx(&actCtx), &ulpActivationCookie);
     return ulpActivationCookie;
}

it's C as code but can be translated to D easy.
