When you open both a message viewer/editor and a hex viewer/editor on the same message, then every time you click or press Enter on a field in the message viewer/editor, the hexadecimal digits in the hex viewer/editor that correspond to that field are displayed in red. Tracking the fields of a NAS message in the hex viewer/editor Before you issue the Paste ( Ctrl+V) command in the hex view, remember to either clear the hex view or to select the entire contents ( Ctrl+A). Likewise, when you use an application that can export a NAS message by copying a hexadecimal string to the clipboard, you can then paste the hexadecimal string directly into the hex viewer/editor. When you use an application that can import a NAS message encoded as hexadecimal strings through the clipboard, you can pass the message to that application by pasting into it. When you select the entire contents of the hex view (e.g., by using Ctrl+A) and then issue the Copy command ( Ctrl+C), the hexadecimal string that is copied to the clipboard will represent an entire NAS message. You can then paste this string into any application that accepts plain text or hexadecimal strings. The string consists entirely of uppercase hexadecimal digits and spaces (ASCII 32). When you issue the Copy command ( Ctrl+C), the contents of the selection are copied to the system clipboard as a string of text in hexadecimal format. Clipboard operationsĪt any time, the selection in the hex view is either empty or consists of a series of consecutive bytes. The Insert key acts as a toggle for the insert/overwrite mode, which is initially set to insert. Within the hex view, all the basic editing operations such as entering text, selecting text, copying, pasting, cutting, deleting, and so on, work as expected for a Windows application, except that most editing operations work with entire bytes (the two digits of a byte plus the surrounding space), not with individual digits. The leftmost column in each line contains the offset (in decimal notation) of the first byte of the line. This number can be changed by issuing the View / Bytes per Line main menu command. Each line in the hex view displays the same number of bytes, which is either a fixed number (4, 8, 10, 16, or 32) or Adaptive (the maximum number of bytes that fit in the width of the window at any time). The hex viewer/editor displays the contents of an encoded message.
When multiple views are open on the same message, any changes you make in one of these views are immediately reflected in the other views.
In addition, when the active window is a message viewer/editor or hex viewer/editor window, you can open a new hex viewer/editor window on the same underlying message by issuing the Window / New Hex Window main menu command. To open a message in the hex viewer/editor, select an encoded message file in the projects pane and issue the Edit as Hex context menu command.
