以前は、Excel VBA で Windows API 呼び出しを使用して、クリップボードにテキストを設定できました。しかし、64 ビットの Office 2013 にアップグレードして以来、できなくなりました。以下はエラーにならないコードですが、クリップボードにテキストを設定していません。誰かがテストとトラブルシューティングを手伝ってくれますか?

以下のコードを VBA のコード モジュールに貼り付けた後、すぐにウィンドウに入力してテストできますClipboard_SetData("Copy this to the clipboard.")。そのテキストがクリップボードに設定され、他のアプリケーションに貼り付けることができます。

(私は Windows 8 を使用しているため、Microsoft Forms や Data Object を使用してクリップボードを操作することはできません。Windows 8 では正しく動作しません。)

更新と編集:以下のコードは修正され、64 ビット Excel で正しく動作するようになりました。以下の Jason Kurtz の回答のおかげです。これが役立つと思われる場合は、彼の回答に投票してください。

わかりました、今わかりました...

コードのバージョンでこの行を変更する必要があります。

Private Declare PtrSafe Function lstrcpy Lib "kernel32" (ByVal lpString1 As String, ByVal lpString2 As String) As LongPtr

これに：

Private Declare PtrSafe Function lstrcpy Lib "kernel32" (ByVal lpString1 As Any, ByVal lpString2 As Any) As LongPtr

コードをステップ実行すると、lstrcopy が呼び出されたときに lpGlobalMemory の値が変化することがわかります。タイプが Any に変更された場合、値は同じままです。

Windows 7で動作します。うまくいくことを願っています!
