【解決方法】スキャンの実装、スキャナーの確認

[ad_1]

やあ、

Windows アプリケーションで Magtek Excella デバイス dll の実装に取り組んだ人はいますか?

MTMICRProcessCheck() メソッドを使用して、一度に n 個のチェックを処理しようとしています。

私の設定オプションでは、DocFeed を AUTOFEED のままにしていますが、処理には 2 回のチェックが必要で、n 個のチェックは必要ありません。
私の結果として、最初にスキャンされたチェックのみの情報を持つ XML 文字列を取得します。

誰かが同じことを実装している場合は、親切に助けてください!
