Search, Navigation, and Selection

HexView splits these workflows across three services.

HexSearchService supports:

  • address parsing
  • raw hex byte search
  • wildcard search
  • text pattern conversion
  • replace-next and replace-all helpers

Typical flow:

if (HexSearchService.TryParseHexBytes("DE AD BE EF", out var pattern))
{
    var found = HexSearchService.FindNextValue(reader, length, pattern, startOffset);
    if (found.HasValue)
    {
        HexView.MoveCaretTo(found.Value);
    }
}

NavigationService tracks:

  • back stack
  • forward stack
  • bookmarks
  • next changed byte

This keeps caret history independent from the control.

Selection

SelectionService owns the current logical range and exposes operations like:

  • Fill
  • Zero
  • Increment
  • Randomize
  • CopyHex
  • CopyAscii
  • PasteHex
  • PasteAscii

The sample keeps the control selection and the service selection synchronized through the SelectionChanged event.
