Many times when we want to use the Richtext applet, we ponder over the download time of the applet to the client. Here is an alternative to the Richtext applet, that is using the Microsoft IE DHTML Editing Component. The component itself allows creation of table on the fly which is not achievable with the Notes Richtext applet out-of-the box.
Click on the link below to download the DHMTL editing component samples. Unzip the file, go to the 'WebEdit' folder samples, copy the html code for each of the html files into a page or a form in domino designer. You need also create all the images into the image resource and modify all <IMG SRC=''> accordingly. To save the content inside the component, save the html content to a richtext field via the 'DocumentHMTL' properties.
