Description
This PDFViewer is a small Windows desktop program whose main job is to let a user open and view PDF files in a built-in viewer window. When it starts, it can automatically open a PDF if one was provided (for example, by double-clicking a file associated with the app or by passing a file path when launching it). If no file was provided, it prompts the user with a standard “Open File” dialog so they can pick a PDF. Once a document is loaded, the window title updates to show the program version and the name of the PDF being viewed.
The program is designed to be practical for real-world PDF, including very large ones. Before opening a PDF inside its own viewer, it checks the file size. If the PDF is larger than a configurable threshold, it warns the user that it may be slow and offers an alternative: open the file in the computer’s default PDF application instead (for example, Adobe Acrobat or the Edge PDF reader). That way, the user can still open the document quickly without the program becoming sluggish or unresponsive. While a PDF is loading or processing, the viewer shows simple progress/status messages (for example, “Opening…” or a percentage complete) so the user understands that work is happening. The program also cleans up after itself: when the user closes the window or opens a different PDF, it releases the previously loaded document from memory and removes any temporary files it created. This helps prevent locked files, wasted disk space, and performance slowdowns over time.
From a user-feature standpoint, the program includes common “document utility” actions through menu items: Open (choose a PDF), Save/Export (save a copy or export from the viewer), Print, Exit, and About. It also provides a Website link for product information and an Update option. On startup (and also through the Update menu), it can check whether a newer version is available from your website and, if the user agrees, download and install that update.

The PDFViewer App is built as a Windows desktop application using Microsoft Visual Basic .NET (VB.NET) and the Windows Forms framework. It uses core .NET libraries such as System.IO to manage files and paths, and System.Reflection to retrieve application metadata like version information displayed in the window title. PDF rendering and document handling are provided by ComponentOne libraries, particularly C1.Document and the FlexViewer components, which load, display, print, and export PDF files inside the application. The app also uses ComponentOne input controls to support a modern, responsive user interface. Together, these technologies allow the PDFViewer App to open PDFs reliably, manage large files efficiently, and integrate update and printing features within a native Windows environment. |
