The following commands support 4D Write Pro areas. You can use them either with a 4D Write Pro form object name (string) or a 4D Write Pro document reference (a variable of the Object type):
Starting with 4D v16, expressions are filtered by default in 4D Write Pro documents and must be explicitely allowed. These commands ignore the virtual structure. For more information, refer to the Managing expressions section. Starting with 4D v16 R5, picture expressions can be inserted (see Picture expressions).
Starting with 4D v16 R4, you can directly handle editable URLs in any 4D Write Pro range (including pictures and cells) using the WP SET ATTRIBUTES and WP GET ATTRIBUTES commands through the wk link url attribute.
