<p CLASS="heading"><A NAME="What">What are the HTML Viewer Components?</A></p>
<P>The HTML component set consists of the <B>ThtmlViewer</B>, <B>TFrameViewer</B>, and <B>TFrameBrowser</B>
components. All three are HTML document display components:</P>
<TABLE WIDTH="100%" CELLSPACING="2" CELLPADDING="2" BORDER="0">

	 <TH WIDTH="2%"></TH>
	 <TH CLASS="maroon" VALIGN="top" ALIGN="left">ThtmlViewer</TH>
	 <TD VALIGN="top">The basic component. <B>ThtmlViewer</B> displays single (non-frame) documents. It also forms
	 the basis for the other two components.<BR>

	 <TD></TD>
	 <TH CLASS="maroon" VALIGN="top" ALIGN="left">TFrameViewer</TH>
	 <TD VALIGN="top">Displays both Frame and single HTML documents. <B>TFrameViewer</B> is oriented more for local

	 <TH CLASS="maroon" VALIGN="top" ALIGN="left">TFrameBrowser&nbsp;&nbsp;&nbsp;</TH>
	 <TD VALIGN="top">Also displays Frame and single HTML documents. However, <B>TFrameBrower</B> is oriented
	 toward Internet style protocols and URL usage. Additional code and/or components are generally required to use
	 <B>TFrameBrowser</B>.<BR>

<P>Version 9 of these components supports most of the HTML 3.2 specifications with many additional popular HTML 4
enhancements. Many Cascading Style Sheet properties are also supported. </P>
