この特定のエラーに関する多数の投稿を読んでいますが、特定の問題を解決するものは見つかりませんでした。
Access 2010 フロントエンド内にいくつかの VBA コードがあります。常にではありませんが、「オブジェクト変数または With ブロック変数が設定されていません」というメッセージが表示されることがあります。エラー。私のコードは次のとおりです。

エラーは、次の 2 つの特定の場所で発生します。
「ケース1」の下：エラーは直後に発生します...
PassedCongressionalDistrict.Value = CInt(metadata.selectSingleNode("congressional_district").nodeTypedValue)
...実行されます。これをデバッグし、ステートメントが正しく実行され、「PassedCongressionalDistrict」オブジェクトの値が正しいことを確認しました。
For ループは最初の項目リストを正しく処理しますが、2 番目の項目に適切で正当なデータがあるにもかかわらず、2 番目の項目の処理を開始するときに識別されたエラーで失敗します。
これで十分に説明できたと思います。(1)これをより完全にデバッグする方法と、(2)すべてのオブジェクト変数が適切に定義されているように見えるため、エラーが発生する理由を理解できないようです。
よろしく、ケン
