Owning Palette: Programming VIs and Functions

Use the String functions to concatenate two or more strings, extract a subset of strings from a string, convert data into strings, and format a string for use in a word processing or spreadsheet application.

Palette Object	Description
Array To Spreadsheet String	Converts an array of any dimension to a table in string form, containing tabs separating column elements, a platform-dependent EOL character separating rows, and, for arrays of three or more dimensions, headers separating pages.
Build Text	Creates an output string from a combination of text and parameterized inputs. If the input is not a string, this Express VI converts the input into a string based on the configuration of the Express VI.
Carriage Return Constant	Consists of a constant string containing the ASCII CR value.
Concatenate Strings	Concatenates input strings and 1D arrays of strings into a single output string. For array inputs, this function concatenates each element of the array.
Empty String Constant	Consists of a constant string that is empty (length zero).
End of Line Constant	Consists of a constant string containing the platform-dependent end-of-line value.
Format Date/Time String	Displays a time stamp value or a numeric value as time in the format you specify using time format codes. Time format codes include the following: %a (abbreviated weekday name), %b (abbreviated month name), %c (locale-specific date/time), %d (day of month), %H (hour, 24-hour clock), %I (hour, 12-hour clock), %m (month number), %M (minute), %p (a.m./p.m. flag), %S (second), %x (locale-specific date), %X (locale-specific time), %y (year within century), %Y (year including century), and %<digit>u (fractional seconds with <digit> precision).
Format Into String	Formats string path, enumerated type, time stamp, Boolean, or numeric data as text.
Line Feed Constant	Consists of a constant string containing the ASCII LF value.
Match Pattern	Searches for regular expression in string beginning at offset, and if it finds a match, splits string into three substrings. A regular expression requires a specific combination of characters for pattern matching.
Match Regular Expression	Searches for a regular expression in the input string beginning at the offset you enter and, if it finds a match, splits the string into three substrings and any number of submatches. Resize the function to view any submatches found in the string.
Replace Substring	Inserts, deletes, or replaces a substring at the offset you specify in string.
Scan From String	Scans the input string and converts the string according to format string.
Search and Replace String	Replaces one or all instances of a substring with another substring. To include the multiline? Boolean input, right-click the function and select Regular Expression.
Space Constant	Use this constant to supply a one-character space string to the block diagram.
Spreadsheet String To Array	Converts the spreadsheet string to an array of the dimension and representation of array type. This function works for arrays of strings and arrays of numbers.
String Constant	Use this constant to supply a constant text string to the block diagram.
String Length	Returns in length the number of characters (bytes) in string.
String Subset	Returns the substring of the input string beginning at offset and containing length number of characters.
Tab Constant	Consists of a constant string containing the ASCII HT (horizontal tab) value.
To Lower Case	Converts all alphabetic characters in string to lowercase characters. Evaluates all numbers in string as ASCII codes for characters. This function does not affect non-alphabetic characters.
To Upper Case	Converts all alphabetic characters in string to uppercase characters. Evaluates all numbers in string as ASCII codes for characters. This function does not affect non-alphabetic characters.
Trim Whitespace	Removes all white space (spaces, tabs, carriage returns, and linefeeds) from the beginning, end, or both ends of string.

Subpalette	Description
Additional String VIs and Functions	Use the Additional String VIs and functions to scan and search in strings, match patterns, and manipulate strings.
String/Array/Path Conversion Functions	Use the String/Array/Path Conversion functions to convert strings, arrays, and paths.
String/Number Conversion Functions	Use the String/Number Conversion functions to convert strings.
XML VIs and Functions	Use the XML VIs and functions to manipulate LabVIEW data in XML format.
