Configuring String Controls and Indicators

Related Information

• Normal Display

  Normal Display displays all characters in a string as typed, with the exception of non-displayable characters. Non-displayable characters generally appear as boxes.

• Backslash ('\') Codes Display

  Backslash mode instructs LabVIEW to interpret characters that immediately follow a backslash (\) as a code for non-displayable characters. Use this mode to debug VIs and to send non-displayable characters to instruments, serial ports, and other devices.

• Password Display

  Password Display displays an asterisk * for each character you enter into a string control, including spaces.

• Hex Display

  Hex Display displays the ASCII value of each character in a string in hex, rather then the characters themselves. Use Hex Display for debugging and communicating with instruments.

• Limit to Single Line

  You can limit the contents of a LabVIEW string constant, control, or indicator to a single line. This option prevents carriage returns and ignores additional lines when you paste multiline text.

• Update Value while Typing

  You can configure a string constant, control, or indicator so that the control updates the block diagram as the user enters characters instead of waiting until the user presses Enter. Use this option to check the correctness of the input or to provide user feedback.

• Enable Wrapping

  Disabling word wrapping for a string control or indicator causes the string to wrap at line breaks instead. Wrapping is enabled by default.
