Version 1.5.0

Advanced Networking & Download Management

This update introduces deep integration with Chromium's networking layer and programmatic control over the download lifecycle.

Added

• HTTP Status Code Tracking (DispId 5):
  • OnWebResourceResponseReceived(statusCode, reasonPhrase, requestUrl): [Event] Captures the HTTP status code for every resource request (e.g., 404, 500), enabling precise error handling in AutoIt.
  • HttpStatusCodeEventsEnabled: (195) [Property] Master switch to enable or disable the status code event entirely.
  • HttpStatusCodeDocumentOnly: (196) [Property] Filters status code events to only trigger for the main document (Default: True). This prevents event floods that cause GUI deadlocks in AutoIt.
• Custom Download Management (DispIds 204 - 211):
  • SetDownloadPath(path): (204) [Method] Forces downloads to a specific folder or file. If a directory is provided, the filename is automatically appended.
  • IsDownloadUIEnabled: (205) [Property] Control visibility of the browser's download bubble.
  • OnDownloadStarting: (208) [Event] Intercepts downloads. Features a simplified contract (URI, DefaultPath). Overrides are now handled via dedicated properties/methods (SetDownloadPath, IsDownloadHandled).
  • OnDownloadStateChanged: (209) [Event] Real-time progress (bytes) and state updates.
  • CancelDownloads(uri): (210) [Method] Cancels downloads. If uri is empty or omitted, cancels all active downloads.
  • IsDownloadHandled: (211) [Property] Set to True during OnDownloadStarting to suppress the default download UI.
  • ActiveDownloadsList: (214) [Property] Returns a pipe-separated string of all active download URIs.
• Enhanced Export & Snapshot Engine (DispIds 201, 207):
  • CaptureSnapshot(cdpParameters): (201) [Method] Direct access to CDP snapshots (e.g., MHTML).
  • ExportPageData(format, filePath): (207) [Method] Simplified HTML/MHTML export. Note: Moved to DispId 207 to distinguish from raw CDP snapshots.
• Binary Data Support:
  • DecodeB64ToBinary(base64Text): (206) [Method] Decodes Base64 to raw byte arrays (binary).
• Manual Download Mode: Added logic to DownloadStarting that checks IsDownloadHandled. If set to True by AutoIt during the event wait loop, the native Edge download is cancelled (e.Cancel = true), allowing AutoIt to handle the download externally (e.g., via InetGet).
• Download Sync-Wait: A 600ms synchronization loop ensures that property changes in AutoIt are correctly picked up by C# before the download proceeds or is cancelled.
• UnLockWebView Method: Added UnLockWebView() (215) to re-enable restricted features previously disabled by LockWebView().
• Zoom Control: Added IsZoomControlEnabled (212) [Property] specify if zoom (Ctrl+Wheel) is enabled.
• Scrollbar Control: Added IsScrollbarEnabled (213) [Property] Toggle scrollbars via CSS overflow injection.

Fixed

• Smart Auto-Fill: Updated Initialize to automatically calculate initial parent dimensions when 0 width/height are provided. Note: Dynamic resizing remains disabled unless $oWeb.SetAutoResize(True) is called explicitly.
• Naming Consistency: Standardized method names (e.g., CaptureSnapshot) across C# and COM interfaces.
• Build Efficiency: Resolved IDE warnings (CS0067) and unnecessary #pragma directives.
• GUI Deadlock (HttpStatusCode): Fixed a critical issue where an flood of 404 resource responses for sub-elements (images, CSS, scripts) would overwhelm the AutoIt event loop, causing the GUI to freeze. Added robust tracking to ensure these events are filtered to the main document by default.
• Download Race Condition Fix: Added Application.DoEvents() to the OnDownloadStarting event to ensure AutoIt property overrides (DownloadResultPath, IsDownloadHandled) are synchronized correctly before the download begins.
• Automatic Directory Creation: Implemented automatic folder creation for custom download paths if the target directory does not exist.
• Event Fixes: Wired up the OnZoomChanged event to correctly trigger when the browser zoom level is modified.
