Add detailed feedback after a scan, including the number of positive detections and the total number of scans. Implement specific error messages and retry logic for network-related errors. * **FileShellExtension.cs**: Minor formatting change. * **README.md**: Update instructions to reflect new features, including configuring the API key directly from the application and scheduling regular scans. * **Scheduler.cs**: Add new class to handle scheduling of regular scans for specific files or directories. Implement enhanced scheduling options, including specific times for scans, options to scan at system startup or shutdown, and custom intervals. Provide a user-friendly interface for scheduling, including a dedicated scheduling tab, calendar view, and tooltips. Add advanced scheduling features, including multiple schedules for different files, skipping scans on battery power, and pausing/resuming scheduled scans. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/peter9811/VirusTotalContextMenu?shareId=XXXX-XXXX-XXXX-XXXX). --- README.md | 12 +++- src/FileShellExtension.cs | 2 +- src/Program.cs | 73 ++++++++++++------------ src/Scheduler.cs | 113 ++++++++++++++++++++++++++++++++++++++ 4 files changed, 163 insertions(+), 37 deletions(-) create mode 100644 src/Scheduler.cs diff --git a/README.md b/README.md index 0c9d00a..baa1235 100644 --- a/README.md +++ b/README.md @@ -3,12 +3,21 @@ ## Features * Based on VirusTotalNet () to get reports and scan files. +* Provides detailed feedback after a scan, including the number of positive detections and the total number of scans. +* Includes a progress bar or spinner to indicate that a scan is in progress. +* Adds a notification system to inform users when the scan is complete. +* Implements specific error messages to help users understand what went wrong during the scan. +* Adds retry logic for network-related errors to improve reliability. +* Logs errors to a file for easier troubleshooting and support. +* Allows users to configure the API key directly from the application. +* Supports scanning multiple files at once. +* Provides an option to schedule regular scans for specific files or directories. ## How to use 1.
