VBA 7.0 でモードレス ポップアップ ダイアログを作成したいと考えています。これまでのところ、最も有望なルートはCreateDialog.
最初に私は試しCreateDialogWて受け取りましEntry point not found for CreateDialogW in DLLた。
DLL を開いた後、この関数がリストされていないことを確認しました。上にリンクされている MSDN リファレンスは、この関数の DLL として User32 を示し、関数名CreateDialogWとCreateDialogA(それぞれ Unicode/ansi) をリストしていますが、私のコンピューター (Win 7 プロフェッショナル、64 ビット) のこの DLL にはリストされていません。
そのため、DLL に含まれる関数のリストを見ると、関数CreateDialogParamとCreateDialogIndirectParam関数(それぞれの Ansi バージョンと Unicode バージョン) が見つかりました。
私は MSDN に従い、C の例を VB に変換しようとしましたが、どこかが欠けていて、何が間違っているのかわからないので、行き詰まっています。コードはエラーなしでコンパイルおよび実行されますが、API 呼び出しでは何も起こりません。実行しても何も起こりません。
誰かが私に正しい方向への指針を与えることができれば、私はそれを大いに感謝します. 私の現在の回避策は最悪です。このプロジェクトをボタンで留めたいと思います。
