タイプ vbPicTypeIcon の stdole.StdPicture オブジェクトがあります。Type vbPicTypeBitmap に変換する必要があります。プロジェクトの制約により、Win32 または VBA を使用してこれを行う必要があります。ファイルのアイコンをコマンド バー ボタンにロードしようとしています。これが私がこれまでに持っているものです。それは素敵な黒い四角を生成します:)私はグラフィックスランドに本当に慣れていないので、それが基本的な質問であれば許してください。

vbAccelerator.comでこの投稿を試してみてください。

編集： 私がVBAで見つけた最も近いものは、officeblogs.netのこの投稿です。ただし、コードはアイコンハンドルではなくアイコンを取ります。

さて、コードをクリーンアップしました。ExtractAssociatedIcon メソッドは 64x64 のアイコンを返すため、この例ではそのサイズをハードコーディングしました。混乱を避けるために、picturebox は削除され、画像はフォームの画像プロパティに割り当てられます。

例: コードを新しいフォームにコピーして実行する

Googleグループで、StdPictureをアイコンからビットマップに変換するというタイトルのスレッドを検索します。

アップデート

いいえ、私もそれを動作させることができません。

しかし、試してみると既視感がひどいものになりました...それから、数年前に間違いなくこれを行ったことを思い出しました。つまり、実行時にExcel CommandBarButtonsにマスク付きのアイコンを追加し、開いているExcelのバージョンがわからなかったのです。残念ながら、コードが見つかりません（ソース管理されていないため、リリースできませんでしたか？動作するようになったとほぼ確信しています）。

私はこれらの記事から多額の借用をしたと思います：

OfficeCommandBarボタンの透明な画像を作成する方法

OfficeXPコマンドバーのマスクと画像のプロパティを設定する方法

また、Excelにはクリップボードがないため、StephenBullenのPastePicture.zipから借用したことを思い出しているようです。

これが野生のガチョウの追跡にあなたを送り出さないことを願っています:)

LoadPicture IPictureDisp をサポートするオブジェクトを返します。ただし、vbPicTypeBitmap ではない場合があります。VBA で GdipCreateBitmapFromFile を呼び出すことができるかどうかはわかりません。
