Logitech G 27プログラム読み出しデータ

実験でLogitech G 27のデータを読み取る必要があるため、DirectXに基づいてプログラムを書いてデータを読み取るのは急いでいるので、ここで簡単にまとめます(必要な友達は一度見れば分かりやすいはずです~~).
開発環境:VS 2008+Qtライブラリ(設計インタフェース)+DirectX SDK
1.ハードウェア接続、電源接続が必要
2.付属のドライバソフトウェアのインストール
3.DirectX SDKのインストール(マイクロソフト公式サイトからダウンロード可能)
4.重要なコードは次のとおりです.

extern DIJOYSTATE2 g_G27State;
extern QMutex g_mutexG27;

G 27クラスの定義:

class CG27 :
	public QThread
{
	Q_OBJECT
public:
	CG27(void);
	~CG27(void);
public:
	bool InitializeG27();
protected:
	void run();
signals:
	void GetG27Info();
};

G 27類関連実現:
