Rich text box

I have developed hospital management software. I designed userform in excel vb and then transported to vb6. I have fields in patient discharge card which involves tables, bold letters, etc. So I need rich text box. I have added it through components and my toolbox show its icon. When I add rtb in userform it is added but I don't know how to make it workable means how to add table, modify text font etc. At present it is working simply as textbox. Please guide me how to code it.
Thanks
