DisplayMode Enumeration
Visual Studio 2008
Defines identifiers that indicate the display modes used by ByteViewer.
Assembly: System.Design (in System.Design.dll)
| Member name | Description | |
|---|---|---|
| Hexdump | A hexadecimal format display. | |
| Ansi | An ANSI format display. | |
| Unicode | A Unicode format display. | |
| Auto | 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. |
The following code example demonstrates how to use DisplayMode identifiers. This code example is part of a larger example provided for the ByteViewer class.
