DisplayMode Výčet
Definice
Důležité
Některé informace platí pro předběžně vydaný produkt, který se může zásadně změnit, než ho výrobce nebo autor vydá. Microsoft neposkytuje žádné záruky, výslovné ani předpokládané, týkající se zde uváděných informací.
Definuje identifikátory, které označují režimy zobrazení používané nástrojem ByteViewer.
public enum class DisplayModepublic enum DisplayModetype DisplayMode = Public Enum DisplayMode- Dědičnost
Pole
| Ansi | 2 | Zobrazení formátu ANSI. |
| Auto | 4 | Režim zobrazení, který automaticky vybere režim zobrazení. V tomto režimu se bajty prověří, aby se zjistilo, jestli jsou hexadecimální nebo tisknutelné. Pokud jsou bajty v šestnáctkovém formátu, Hexdump je vybraný režim. Pokud se znaky shodují s tisknutelnou znakovou sadou, spustí se test, který automaticky vybere Ansi režim zobrazení nebo Unicode . |
| Hexdump | 1 | Zobrazení šestnáctkového formátu. |
| Unicode | 3 | Zobrazení formátu Unicode. |
