サブ内の関数を使用して特定のフォルダからPPTXを開こうとしています。関数の目的は、残りのマクロのコードで実行するファイルを選択することです(基本的にActivePresentationにする)。問題は、PickDir()関数を呼び出してファイルのパスを取得して開くときに、マクロ実行を停止します。だから、私はただのプレゼンテーションをして、私がやりたいアクションを実行していない。ディレクトリからPowerPointを開き、マクロを再開
問題はすべての変数がDim'dされた後約5行で発生します。

のoPresを使用し、その後、私の答えは、おそらく正しくありませんでしたので、あなたは非常に明確にされていなかったことに気づきました。エラーメッセージが表示されますか?実行を停止する場所を正確に確認するためにコードをステップ実行しようとしましたか? – mkingston
