dカードの改悪三昧

dカードが改悪続きで嫌になる。昨年分のご利用特典1万円分は今年は更に利用範囲が狭まり、うちで利用出来そうなのは高島屋のギフトとかしかなく、選択した海鮮は

これで1万円ってどうなの? これさ、高島屋がぼったくりなのかdカードが1万円って言っても実質5,000円程度しか高島屋に入らない仕組みなのかは分からないが、消費者なめ切ってますね😠

ああっ、ホタテ(65g/pack)は楽天とかでたまに購入してた事があるけど、五千円で1㎏とか届くよ? いくらは最近の相場は上がってるとは思うけど、こんな小さなパックでって80gなんだが、楽天でも80gパックが3,980円とか高級なのもあるが、250gパックが四千円以下で結構ある。

昨年まではdショッピングで使えたりしたのに改悪ばかりでドコモとの決別を早期に検討する必要がありそうです。

サポート対象外?

JV-Link Versioin 5.0.0 64bitは、まあ、これまでのJV-Linkと大差ないものって認識をしてみました。当初、まだVisual Studio 2019だった頃、確かにプロジェクトで.NET Frameworkを選択する必要がありました。これ、Visual Studio 2019がまだ32bitだったりしたのでそれで使えばActiveXとかの関係からかツールボックスにJV-Linkが表示されてフォームに貼り付けて利用できた。Visual Studio 2022から64bit化され一時は使えないって感じだったけど、こちらもプロジェクトの参照にJV-Linkを追加して設定を変えて、フォームへの貼付ではなく、単にクラスを宣言する方法にする事で利用可能でした。

もしかして、今回のバージョンもそうなのでは?って事で昨晩試しました。

「次へ」

プロジェクト名は何でもいいけど「次へ」

このままでも良いけど、さらだは.NET 9でないとダメですが「作成」

開いた状態だとこんな感じになってますが、[プロジェクト(P)]-[COM 参照の追加(C)...]で

"JRA-VAN Data Lab. 1.1.8タイプ ライブラリ"左にチェック入れて「OK」すると

依存関係にCOMが追加され展開すると

Interop.JVDTLabLibがあり、それをクリックして

プロパティ見ると「相互運用型の埋め込み」が「はい」になっているので「いいえ」に変更し、

あとは、この使い方ではフォームにJVLink Classを貼り付けようとしてもツールボックスには表示されませんのでフォームのコードでクラス宣言し、プラットフォームをx64にすれば使えますね。

namespace JVLink64Test;

public partial class Form1 : Form
{
    JVDTLabLib.JVLink clsJVLink = new JVDTLabLib.JVLink();
    public Form1()
    {
        InitializeComponent();
    }
}

プラットフォームの追加変更はJRA-VANでも詳しく載ってますので割合します。フォームにメニューを追加して

「JV-Linkの設定(J)...」メニューのイベントに

    private void mnuSettingJVLink_Click(object sender, EventArgs e)
    {
        try
        {
            int iReturnCode = clsJVLink.JVSetUIProperties();
            if (iReturnCode != 0)
            {
                MessageBox.Show(String.Format("エラーコード:{0}", iReturnCode), "JVSetUIProperties", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message, "JVSetUIProperties", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }

って感じにすれば、実行すると

普通に起動して、メニューから[設定(C)]-[JV-Linkの設定(J)...]とすれば

下の方を見るとしっかり"JVLink Version : 5.0.0 (64bit版)"となっているのが見れます。

まあ、これはそれ程苦労せずに分かったのですが、問題はここからです(笑) 自分のアプリは当然ながら32bitで動かしてきたのでが、ここでプラットフォームをx64に変更し、古いってか、32bit版のJV-Linkへの参照を一旦削除して、もう一度COM 参照を追加するとしっかりかわるのですが、コードはそう簡単ではないですね。まずはJVGetのSafeArray関連で引っかかります。これまでは

// JVGetsとSafeArray関連
strFileName = new string('\0', iNameSize);
object objBuff = (object)(IntPtr)0;

と宣言してましたが、まあ、ここはそれ程重要ではないかもですが、 

object objBuff = null;

とobjBuffの部分を変更、 

// JVGets で１行読み込み
iReturnCode = SaraD.clsJVLink.JVGets(ref objBuff, iBuffSize, out strFileName);
if (iReturnCode > 0)
{
    bBuff = new byte[iReturnCode];
    IntPtr pSafeArray = (IntPtr)(int)objBuff;
    try
    {
        uint hr;

        IntPtr ppvData = (IntPtr)0;
        hr = SafeArrayAccessData(pSafeArray, ref ppvData);
        if (hr != 0) throw new System.Exception(hr.ToString());

        Marshal.Copy(ppvData, bBuff, 0, iReturnCode);

        SafeArrayUnaccessData(pSafeArray);
    }
    finally
    {
        SafeArrayDestroy(pSafeArray);
    }
}

JVGet後の取得多バッファはSafeArray使ってこんな感じにしてた部分は 

IntPtr pSafeArray = IntPtr.Zero;

if (objBuff is IntPtr ptr)
{
    pSafeArray = ptr;
}
else if (objBuff is long l)
{
    pSafeArray = new IntPtr(l);
}
else if (objBuff is int i)
{
    pSafeArray = new IntPtr(i);
}
else if (objBuff != null)
{
    pSafeArray = new IntPtr(Convert.ToInt64(objBuff));
}

// ポインタが正しく取れているか念のためチェック
if (pSafeArray != IntPtr.Zero)
{
    uint hr;
    IntPtr ppvData = IntPtr.Zero;
    try
    {
        hr = SafeArrayAccessData(pSafeArray, ref ppvData);
        if (hr != 0) throw new System.Exception($"SafeArrayAccessData Error: {hr}");

        Marshal.Copy(ppvData, bBuff, 0, iReturnCode);

        SafeArrayUnaccessData(pSafeArray);
    }
    finally
    {
        SafeArrayDestroy(pSafeArray);
    }
}

としなければエラーが出てしまう。更に、このbBuffに格納される内容がどうもズレてくる感じまでは昨晩分かったけど、今日はその辺りのデバッグですorz

追記 2026.8.8 13:04
デバッグ進めると、まあ、今回はGeminiなんですが、騙されてました。上記のJVGets関連ですが、まず、objBuffの変更ですが、

object objBuff = new byte[0];

とするのが正解でした。更に、どうやら32bit版ではSafeArray使ってメモリの解放をする必要があったのですが、

ＶＢ以外の言語では、VARIANT*によってバイト型 SafeArray のポインタを受け取り、Return する際 にJV-Link内部で確保したByteSafeArrayをセットして返します。 途中の動作はすべてJVRead と共通しているので、JVGets → JVRead → JVGets というように交 互に呼ばれたとしても、矛盾なくレコードが取得できるように構成されています。 また、JVGets ではメモリの解放を行わないので、アプリケーション側で読み出しの度に解放する必 要があります。

どうやらその必要が無くなる様で、

if (objBuff is byte[] returnedBytes)
{
    if (returnedBytes.Length == iReturnCode)
    {
        bBuff = returnedBytes;
    }
    else
    {
        // 万が一、割り当てられたバッファ長と iReturnCode に差がある場合のみ切り出し
        bBuff = new byte[iReturnCode];
        Array.Copy(returnedBytes, bBuff, iReturnCode);
    }
}

としておけば、メモリリークの心配も無いとの事。

追記 2026.8.8 13:51
無事にフルセットアップがx64で終わりました。

微妙にメモリリークが出てる気がするしorz 遅くなったのは不明ですね。

JV-Link 64bit版

流石はJRA-VANです。やる事が全く時代錯誤だし、ユーザーの事も開発者の事も全く気にせず我が道を行きますね。.NET Frameworkから.NET5になったのって多分これって毎年上がってきて今.NET10で更に数か月後には.NET11になる予定だったかと。つまり、7年程前に戻されるってIT業界ではなかなかない話だと。

どうせ自社で開発ではなく、外注に出したんだと思うけど、それ受けてやった会社もどうかしてるわ。どんだけ技術力がないと7年前に資産にしがみついて新たなソフトを作成するんだろ? ってか多分年配で新しい技術とか全く気にせずに昔からのノウハウだけで開発請け負って、「どうですか? いい出来でしょ?」って自慢気に作ったんだろうなorz

盆休みは一気に64bit化だって意気込んでみたけど、やる気が...

Microsoft Rewards 31回目

前回が7月2日なので34日目なので前回よりは速いのは、前回はMicrosoftが在庫切れで貯まって即って行かずに待たされたってのと、その反動的に交換分以上に貯まった状態からだったってのはありますね。まあ、なんにしても継続は力なり👍

ゲリラ提供?

何の前触れもなくJRA-VANはメンテ明けでJV-Linkの64bit化をアナウンスしてます(笑) こりゃ良いのか悪いのかなんですが、実は盆休みに本腰入れて「さらだ64」に取り組もうかと思ってましたが、逆に良かった。無駄が省けそうなんで、この連休使って可能な限り64bit化をします。が、予定ではさらだ64はWinUI3で行く予定だったのでその辺りの調整は必要です。

でも、JV-Link Version 5.0.0はウェルカムです^^

こちらは随分と頑張ってる感じがしますが、でも、もう一押し欲しいんだよね。今回、まあ、ボーダー0は一区切りして、ボーダー500を攻める予定なんだけど、流石に葉を399までしたし、葉の最初も80にあげてるので、モデルサイズが13MB超えにはなってます。自分の感覚的にはやはりボーダー500の方が検証結果的には上かな?

モデルサイズ的にはまたもう少し肥大化しても耐えられそうなので、攻めようかと思うけど、まあ、正攻法的には多分葉を増やすんだと思うので、ここは葉を415にして20回試してみます。20回なら寝る前に条件替えて40回とかも行けるしね。

目指すべきもの

サボってはないですよ(笑) 今週末も学習させながらコーディングもしてます。まあ、AIとじゃれてるってのもあるが^^; 先日書いたEarlyStoppingRoundの現状バージョンでは実装不可ってのをAIではなく人間が挑んだらどうかって事で今週末やってるんだけど、まあ、結局AIのサポートも受けないと出来ないので「じゃれてる」って事になる(笑) これ、実際にはそれ程重要な事でもない気もしてるが、もし実装できればそれはそれでね。でも、結局は諦める事に^^;

多分、実装するのに必要なスキルがGeminiにもCopilotにも、更には自分にも無いのが原因な気もするし、そもそもML.NET側のバグかもしれませんが、ここはそれ以上の追及はしない事にしました。

で、ランキング学習ですが、モデルのダイエットも兼ねてイテレーション数を減らしました。これね、EarlyStoppingRoundが実装出来れば、また違った感じに出来たかもですが、実装出来なかったものを期待しても仕方がないので人力で変更(笑)

AIに騙される

ここ数日はGeminiに騙されて無駄な時間を費やし、昨夜、CopilotにGeminiに騙されたけどお前は出来る?って訊くと自信満々に言うので、仕事終えて帰宅して、ではお願いって感じでコード提示してもらうと、まあ、想定内でGeminiとは大差ない。で、まあ、問い詰めるとサラッと謝罪する始末(笑)

じゃあ、ああっ、その過程でやってたのはEarlyStoppingRoundの導入なんだが、結局どちらもこれの実装はまだ完璧じゃないから利用出来ないって事でした。そこで、ここまでの最適パラメーターを見せてどうすれば良いかを尋ねると

既に手詰まり一歩手前

ここまでパラメーターを色々と変えて試すもこれといったものが得られない。先日ゲリラ雷雨で中断してたパターンを昨晩50回やったけど、結局あの2回目超えるものは出なかった。これ、単に運が悪いだけかもですが、まあ、そんなものです。次の一手は乗数をチョイ上げてみた。40回でスタート。
