A Write Pro document can be initialize using the WP New command. A source parameter can also be passed to the WP New command to create a new document with content based on the source. The source can be one of three types:

• A BLOB containing a 4D Write or 4D Write Pro document file.


• An Object of a 4D Write Pro document, range, or element.


• A string of an HTML source.

When using a string of an HTML source, if the data is not properly formatted as HTML the command can throw an error.
For example the following code will generate a 106 Error:

C_OBJECT($WP_obj) $WP_obj:=WP New("&")

This is because many symbols, including the ampersand, need to be encoded.
Below is a utility method that will automatically format a text so that symbols are HTML encoded and returns a WP document containing the text:

// Util_Text_To_WPDoc C_TEXT($1; $input_t) C_TEXT($tag_t) C_TEXT($stmt_t) C_TEXT($result_t) If (Count parameters=1)    $input_t:=$1       $tag_t:="<!--#4DTEXT \"\"-->"    $stmt_t:=Insert string($tag_t; $input_t; 14)       PROCESS 4D TAGS($stmt_t; $result_t)    $0:=WP New($result_t) End if

Below is an example of using the method with the initial example that failed:

C_OBJECT($WP_obj) $WP_obj:=Util_Text_To_WPDoc("&")
