Character string: How to extract, remove and replace words?
This page presents the main operations that can be performed on a character string.
String literals: single-line and multiline strings
String literals are used to represent and manipulate data as a sequence of characters. For example, string literals can be used to display information, define a constant, etc.
fInsertTextAtBeginning (Function)
Inserts text at the beginning of a file without overwriting the existing text.
<ANSI string>.CharactTypeCount (Function)
Returns the number of characters matching a given type.
WordCount (Function)
Returns the number of words in a string.
LineToPosition (Function)
Returns the position of the first character of a line in a block of text.
StringReverse (Function)
Reverses the characters of a string.
ASCIIZ string of (Variable type)
The ASCIIZ string of type is used to manipulate strings with a null character at the end, denoted by a zero (as in the C programming language).
<ANSI string>.Insert (Function)
Inserts a string into another character string at a given position.
PositionToLine (Function)
Returns the number of the line that contains a character identified by its position in a block of text.
RTFReplace (Function)
Replaces or inserts a character string in an RTF control (found in a window or in a report) or in a string in RTF (containing a text in RTF).
String (Variable type)

Converts an ANSI string to an XML string.
Length (Function)
Returns:
  • the length of a string, i.e., the number of characters in the string (including spaces and binary zeros).
  • the size of a buffer, i.e., the number of bytes in the buffer.
ExtractLine (Function)
Extracts a specific line from a character string.
UUEncode (Function)
Encodes a character string according to the UUEncode algorithm.
Functions for managing RTF controls

gToText (Function)
Deletes the graphic elements from a character string that uses gStoredValue, gImage, ...
String of (Variable type)
The String of type is used to manipulate fixed-length strings. These strings have a null character at the end, denoted by a zero (as in the C programming language).
Unicode string on (Variable type)
The type Unicode string on is a fixed-length string containing only characters in Unicode format.
<ANSI string>.Reverse (Function)
Reverses the characters of a string.
WordToArray (Function)
Fills an array with the words from a string.
Multilingual messages: Convert to new format (version 27 and later)
WINDEV, WEBDEV and WINDEV Mobile have included multilingual project support in many previous versions...
Phonetic (Function)
Returns the phonetic transcription of the string passed as parameter.
CharactTypeCount (Function)
Returns the number of characters matching a given type.
Translating programming messages
When developing a multilingual application, you can translate the different messages displayed to the user (messages displayed by Info and YesNo, for example.
<Table>.ToText (Function)
Creates a character string from the data found in a Table or TreeView Table control.
Pascal string of (Variable type)
The Pascal string of type corresponds to a length-prefixed string (this length is stored as a byte value). This type of variable is kept for backward compatibility.
<DiskFile variable>.Find (Function)
Finds a character string or a buffer in a file opened by fOpen.
<ANSI string>.Increment (Function)
Increments a number at the beginning or at the end of a string.
Project string manager
WINDEV, WEBDEV and WINDEV Mobile include a string management tool that allows you to view and manipulate all the strings used in the project (or in an element of the project)...
