DisplayMode Enumeração
Definição
Importante
Algumas informações se referem a produtos de pré-lançamento que podem ser substancialmente modificados antes do lançamento. A Microsoft não oferece garantias, expressas ou implícitas, das informações aqui fornecidas.
Define os identificadores que indicam os modos de exibição usados pelo ByteViewer.
public enum class DisplayModepublic enum DisplayModetype DisplayMode = Public Enum DisplayMode- Herança
Campos
| Ansi | 2 | Uma exibição de formato ANSI. |
| Auto | 4 | Um modo de exibição que seleciona automaticamente um modo de exibição. Nesse modo, os bytes são examinados para determinar se eles são imprimíveis ou hexadecimais. Se os bytes estiverem em formato hexadecimal, o modo Hexdump será selecionado. Se os caracteres correspondem a um conjunto de caracteres imprimíveis, um teste será executado para selecionar automaticamente o modo de exibição Ansi ou Unicode. |
| Hexdump | 1 | Uma exibição no formato hexadecimal. |
| Unicode | 3 | Uma exibição no formato Unicode. |
