Abstract: A method, apparatus, and article of manufacture for providing a programming development environment that supports the development of Internet and Intranet applications. A utility allows visual selection and/or manipulation of HTML pages or forms. A user may select control from one form or HTML page and insert it into another HTML page. This results in the applet code associated with the selected control being inserted into the code for the HTML page being displayed in a code editor window or form editor window. The development computer also performs a dependency check for other codes and/or controls upon which the inserted applet depends and issues warnings or performs automatic inclusion of the dependency code and/or control.
