DisplayMode-Enumeration

Definiert Bezeichner, die den von ByteViewer verwendeten Anzeigemodus angeben.

Namespace: System.ComponentModel.Design
Assembly: System.Design (in system.design.dll)

Syntax

'Declaration
Public Enumeration DisplayMode
'Usage
Dim instance As DisplayMode

public enum DisplayMode

public enum class DisplayMode

public enum DisplayMode

public enum DisplayMode

Member

	Membername	Beschreibung
	Ansi	Eine Anzeige im ANSI-Format.
	Auto	Ein Anzeigemodus, der automatisch einen Anzeigemodus auswählt. In diesem Modus werden die Bytes darauf hin überprüft, ob sie hexadezimal oder druckbar sind. Wenn Bytes im Hexadezimalformat vorliegen, wird der Hexdump-Modus ausgewählt. Wenn die Zeichen mit einem druckbaren Zeichensatz übereinstimmen, wird ein Test ausgeführt und entweder der Ansi-Anzeigemodus oder der Unicode-Anzeigemodus automatisch ausgewählt.
	Hexdump	Eine Anzeige im hexadezimalen Format.
	Unicode	Eine Anzeige im Unicode-Format.

Hinweise

Mit den DisplayMode-Bezeichnern wird der Anzeigemodus angegeben, in dem die einzelnen Bytesequenzen angezeigt werden.

Beispiel

Im folgenden Codebeispiel wird die Verwendung der DisplayMode-Bezeichner veranschaulicht. Dieses Codebeispiel ist Teil eines umfangreicheren Beispiels für die ByteViewer-Klasse.
