Description

An API is used to load a HTML file and an image from the MIME repository and save them in internal tables. The method LOAD_DATA of the class CL_GUI_HTML_VIEWER is used to associate the data with the HTML control of CFW and the HTML file is displayed. The name of the image in the HTML file is the same as the URL passed to the method LOAD_DATA for the image. LOAD_DATA is given a URL for the image in the internal table and is used on the HTML page.
