DisplayMode Enum
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Defines identifiers that indicate the display modes used by ByteViewer.
public enum class DisplayModepublic enum DisplayModetype DisplayMode = Public Enum DisplayMode- Inheritance
Fields
| Name | Value | Description |
|---|---|---|
| Hexdump | 1 | A hexadecimal format display. |
| Ansi | 2 | An ANSI format display. |
| Unicode | 3 | A Unicode format display. |
| Auto | 4 | A display mode that automatically selects a display mode. In this mode, the bytes are examined to determine if they are hexadecimal or printable. If the bytes are in hexadecimal format, the Hexdump mode is selected. If the characters match a printable character set, a test is run to automatically select either the Ansi or Unicode display mode. |
Examples
The following example demonstrates how to use DisplayMode identifiers. This code example is part of a larger example provided for the ByteViewer class.
