The HexEdit control is a plain hex editor wrapped in a CEdit derived class called
CHexEdit. Where ever you use a CEdit class you can replace it with the CHexEdit class.
CHexEdit supports the following features:
- Addressdisplay can be short or long or turned off.
- Hexdisplay can have any width between 1 and 256 bytes or turned off
- Asciidisplay can have any width between 1 and 256 bytes or turned off
- Editing in hex or ascii mode
- cut/copy/paste support (text and/or binary format, binary compatible with DevStudio)
Undo is in the context menu but not implemented right now. Horizontal scrolling is also
not supported right now.
