Devpad is a free software program for Windows Vista, 7, and 8/8.1 that functions like VB.Net's multi-tab source code editor. It is designed for coding and editing in multiple tabs, and is open source.

One of the most important features of any code editor is syntax highlighting and line numbering, and Devpad doesn't disappoint in that regard. The color coding and line numbering allow for easier navigation and understanding of your code.
Another standout feature of Devpad is its ability to import files from various sources, including FTP, archives, FlowDocuments, and Rich Text Documents, making it easy to import your existing projects into the editor. Additionally, exporting your files to various formats, such as Wordpress, FTP, Archives, Images, FlowDocuments, Rich Text Documents, and Webpages, allows for easy sharing and publication of your work.
Lastly, Devpad is powered by AvalonEdit, a powerful text editor library that enables developers to add advanced text editing features to their applications. This library is an excellent addition to Devpad, helping to make it a robust and reliable software tool for developers.
Overall, Devpad is an impressive source code editor that offers comprehensive language support, syntax highlighting, and importing/exporting capabilities. Whether you're a beginner or seasoned developer, Devpad is a great tool to have in your toolkit.
