Metro 版：

	void ArtFontBuilderPanel::GetFontFaces()
	{
		vector<wstring> vs;


		HRESULT hr;
		ComPtr<IDWriteFontCollection> pFontCollection;

		hr = ArtCanvas::DWriteFactory->GetSystemFontCollection(&pFontCollection);
		

		UINT32 familyCount = 0;

		if (SUCCEEDED(hr))
		{
			familyCount = pFontCollection->GetFontFamilyCount();
		}


		uint32 index = 0;
		BOOL exists = false;
		wchar_t localeName[LOCALE_NAME_MAX_LENGTH];

		// Get the default locale for this user.
		int defaultLocaleSuccess = GetUserDefaultLocaleName(localeName, LOCALE_NAME_MAX_LENGTH);

		for (UINT32 i = 0; i < familyCount; ++i)
		{
			ComPtr<IDWriteFontFamily> pFontFamily;

			// Get the font family.
			if (SUCCEEDED(hr))
			{
				hr = pFontCollection->GetFontFamily(i, &pFontFamily);
			}

			ComPtr<IDWriteLocalizedStrings> pFamilyNames;

			// Get a list of localized strings for the family name.
			if (SUCCEEDED(hr))
			{
				hr = pFontFamily->GetFamilyNames(&pFamilyNames);
			}

			if (SUCCEEDED(hr))
			{
				// If the default locale is returned, find that locale name.
				if (defaultLocaleSuccess)
				{
					hr = pFamilyNames->FindLocaleName(localeName, &index, &exists);
				}
				if (SUCCEEDED(hr) && !exists) // if the above find did not find a match, retry with US English
				{
					hr = pFamilyNames->FindLocaleName(L"en-us", &index, &exists);
				}
			}

			// If the specified locale doesn't exist, select the first on the list.
			if (!exists)
			{
				index = 0;
			}

			UINT32 length = 0;

			// Get the string length.
			if (SUCCEEDED(hr))
			{
				hr = pFamilyNames->GetStringLength(index, &length);
			}

			// Allocate a string big enough to hold the name.
			wchar_t* name = new (std::nothrow) wchar_t[length+1];
			if (name == nullptr)
			{
				hr = E_OUTOFMEMORY;
			}

			// Get the family name.
			if (SUCCEEDED(hr))
			{
				hr = pFamilyNames->GetString(index, name, length+1);
			}

			// Add the family name to the String Array.
			if (SUCCEEDED(hr))
			{
				vs.push_back(name);
			}

			delete [] name;
		}
		mFontFaceComboBox->iListBoxWidth=mFontFaceComboBox->getWidth()*2;
		
		std::sort(vs.begin(),vs.end());
		for (wstring s:vs)
		{
			mFontFaceComboBox->addItem(s);
		}
