.NETアプリでドメインを直接解決

組み込みのDNSサポートにより、ドメイン名をIPアドレスに変換できるため、柔軟性、保守性、接続の信頼性が向上

DNS support in an internet communication component refers to the ability to resolve domain names into IP addresses, enabling applications to connect to remote services using human-readable URLs rather than numeric IP addresses. This capability allows developers to build more flexible and maintainable networking features, as endpoints can be referenced by domain name even when the underlying IPs change. It simplifies configuration, supports dynamic address management, and enhances compatibility with modern infrastructure such as load balancers and cloud services. By handling domain resolution internally, the component can also offer improved performance through caching and error handling tailored to application needs.

Several .NET Core communications and messaging components offer DNS support including:

  • IPWorks .NET Edition by /n software lets you embed DNS queries enabling your app to resolve hostnames and inspect response metadata.
  • PowerTCP Sockets for .NET by Dart Communications facilitates DNS resolution by providing full control over queries, enabling hostname and mail server lookups.
  • SocketTools .NET Edition by by Catalyst Development Corp. allows you to integrate DNS control within your app, resolving domain names and mail servers.
  • Clever Internet .NET Suite for C#, VB.NET, ASP.NET enables DNS lookups and also acts as a DNS server, supporting query resolution and zone management.

ユーザーがPDFドキュメント内で直接フォームフィールドに入力、検証、送信できるようにして、より高速で正確なデジタルワークフローを実現

Filling out PDF form fields allows users to enter information directly into interactive elements within a PDF document such as text boxes, checkboxes, dropdowns, and signature fields. This functionality transforms static PDFs into dynamic fillable forms that can be completed digitally, reducing the need for printing or manual data entry. The ability to fill, validate, and submit forms directly within a PDF viewer improves efficiency, accuracy, and user experience while supporting accessibility and cross-platform use. Common use cases include completing applications, registration forms, surveys, contracts, and approval documents, making it an essential feature for businesses looking to streamline document-driven workflows.

Several .NET WinForms PDF Viewers feature support for form filling, including:

  • DevExpress WinForms PDF Viewer (part of DevExpress WinForms) lets you complete and submit interactive PDF forms directly within applications.
  • Telerik UI PDF for WinForms (part of Telerik UI for WinForms) enables users to enter, validate, and manage form data seamlessly within PDFs.
  • PDFView4NET Windows Forms Edition allows you to fill, edit, and save PDF form fields with ease, supporting dynamic, data-driven document interaction.
  • Syncfusion Windows Forms PDF (part of Syncfusion Essential Studio Enterprise) facilitates efficient form filling, validation, and submission inside PDF documents.

棒グラフと縦棒グラフは、複雑なデータセットをアクセスしやすく読みやすいグラフィックに変換し、ビジネスユーザーとデータアナリストの両方にとって最適

Column and bar charts form fundamental visualization tools in many charting suites. These chart types use vertical (column) or horizontal (bar) bars to represent quantitative data across categories, making them ideal for straightforward comparisons. Typically, you can display single or multiple series, stack values to show cumulative totals, or group categories to highlight differences. Their simplicity and clarity make column and bar charts a staple in dashboards, business reports, and analytics applications where rapid insight is required.

Several ASP.NET Core chart controls offer support for column & bar charts including:

  • DevExpress ASP.NET Core Chart (part of DevExpress ASP.NET and Blazor) includes support for both column and bar series, with examples for stacked variations.
  • ComponentOne Charts for ASP.NET MVC (part of ComponentOne Studio ASP.NET MVC by MESCIUS) supports both column and bar charts and offers stacked and floating bars.
  • Telerik ASP.NET Core Chart (part of Telerik UI for ASP.NET Core) supports column and bar series, allowing developers to choose orientation and stack/group features.
  • Infragistics ASP.NET Core Charts (part of Infragistics Professional) offers a range of chart types including bar and column, allowing for 2D and 3D variations and layering.

処理パフォーマンス大幅改善

10月 21, 2025
数式・帳票テンプレート・ファイル操作の処理性能が飛躍的に向上し、開発効率と実行速度が改善されました。

このバージョンでは、Excel操作APIとして重要な数式処理・帳票テンプレート生成・ファイル操作の３領域において、処理パフォーマンスの大幅な改善が実現されています。具体的には、VLOOKUP、XLOOKUP、HLOOKUP、LOOKUP、MATCH、XMATCH、UNIQUE など幅広い検索・計算系関数に対し、大規模な範囲に対する文字列検索性能が強化されました。また、AVERAGEIF の条件付き平均や POISSON.DIST、COMBIN といった関数でも、大きな引数を扱う場面での実行速度が改善されています。

帳票テンプレートの分野では、ITableDataSource を利用して大規模データを処理する際のメモリ使用量が削減され、長大な帳票を生成する際のシステム負荷が軽減されています。また、ワークブックの開閉や保存時に DefinedNames が多数含まれている場合でも、処理が速くなっており、ファイル操作の効率性も上がっています。

Excel帳票・計算処理を伴う業務アプリケーション開発において、特に大量データを扱ったり複雑な数式やテンプレートを頻用している開発現場では、V8J SP2の性能改善は即効的な効果が期待されます。

V8J SP2の新機能については、リリースノートをご覧ください。
