Buffer (Type de variable)
The Buffer type corresponds to a binary memory area.
<Type Buffer>Decode (Function)
Decodes a character string that was encoded by Encode.
<Type Buffer>Encode (Function)
Encodes a character string or a buffer. To decode the result, simply use Decode.
BufferToPhrase (Function)
Converts a buffer to a mnemonic phrase using the BIP39 algorithm.
diffApply (Function)
Applies a difference buffer to a specific buffer.
Right (Function)
Extracts the last characters from a string or string buffer.
BufferToInteger (Function)
Extracts an integer from a binary buffer at a given position.
Middle (Function)
Extracts:
  • a substring from a string starting at a specified position.
  • part of a buffer starting at a specified position.
BufferToReal (Function)
Extracts a real from a binary buffer at a given position.
Encode (Function)
Encodes a character string or a buffer. To decode the result, simply use Decode.
StringDisplay (Function)
Returns a specific string (or a buffer) to the client browser in response to a request.
Left (Function)
Extracts the left part (i.e., the first characters) from a string or buffer.
HexaToBuffer (Function)
Converts a string with hexadecimal bytes to a binary buffer.
BufferToURI (Function)
Saves the contents of a buffer to a resource identified by its URI.
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.
fAddBuffer (Function)
Adds the content of a buffer at the end of a file.
fIsImage (Function)
Determines whether a file on disk or in a buffer corresponds to an image format recognized by WINDEV or WEBDEV.
fLoadBuffer (Function)
Loads the content of an external file (text, image, ...) in a buffer variable.
<ANSI string>.BufferToHexa (Function)
Converts an Ansi or Unicode string into a displayable hexadecimal string (e.g. "4A 5B 00").
<DiskFile variable>.Find (Function)
Finds a character string or a buffer in a file opened by fOpen.
Decode (Function)
Decodes a character string that was encoded by Encode.
fFind (Function)
Finds a character string or a buffer in a file opened by fOpen.
fSaveBuffer (Function)
Creates and fills a text file with the content of a string or buffer variable.
BufferToHexa (Function)
Converts a buffer to a hexadecimal string (e.g. "4A 5B 00").
Truncate (Function)
Truncates the right part of a string or buffer.
diffCreate (Function)
Compares two buffers and creates a buffer containing the differences between these two buffers.
