VBAを使用してExcelで生成されたコード128のバーコードを取得しようとしています。誰かが作成してVBForumsで共有したVBAクラス（Excel VBAで動作するように変更されたもの）が見つかりましたが、動作させるのに問題があります。Excel VBAを使用したコード128のバーコードの生成
Excelマクロが有効なスプレッドシートで以下のコードを使用すると、入力にCode128_Str（）関数を使用しようとすると#VALUEエラーが発生します。
コードを正しくデバッグするためのスキルが不足しています。このスクリプトを修正することができれば、同じことをしようとする多くの人にとっては非常に便利だと思います。問題のスクリプトはフリーフォントを使用して、関連するCode 128出力バーコードを生成します。

'UDFと#VALUEを取得するための一般的な理由は、入力引数のいずれかがに従って正しいtype'がに変換することができないということですhttp://stackoverflow.com/質問/ 4170983/vba-udf-returning-value あなたは '= Code128_str（" TESTING "）'のようにexcelで関数を呼び出しますか？ダブルクォートで – Larry
ありがとうラリー！私は '= Code128_Str（A1）'（A1は変換する値を持つセル）のような関数を呼び出していましたが、 '= Code128_Str（" TESTING "）'と '= Code128_Str（1234）'のように呼ぶことも試みました。これらのすべてが同じ '＃VALUE'エラーを返します。理想的には、このコードを正しくデバッグする方法を理解する必要があります。現時点ではコード自体にエラーはなく、行のどこかに問題があるためです。 – shigzy
こんにちはOP、私の質問は今あなたはExcelスプレッドシートまたはVBAから関数を呼び出すことですか？ – Larry
