    public class Class1 extends DhDocument
    {
       public Class1()

          initForm();
       }
       private void initForm() {
       }
       protected void onDocumentLoad(Object sender, Event event)
       {
          DhElement el = this.findElement("coloredText");
          try
          {
             this.newLine();
             this.addText("ForeColor:"+el.getForeColor().toString());
          }
          catch(Exception e1)
          {
             this.newLine();
             this.addText(e.toString());
          }
          try
          {
             el.setForeColor(Color.BLUE);
             this.newLine();
             this.addText("ForeColor:"+el.getForeColor().toString());
          }
          catch(Exception e2)
          {
             this.newLine();
             this.addText(e.toString());
          }
       }
    } 


  7. Modify Page1.html as follows:
    
    <HTML>
    <BODY>
    <hr>
    <OBJECT classid="java:com.ms.wfc.html.DhModule"
        height=0 width=0 ... VIEWASTEXT>
    <PARAM NAME=__CODECLASS VALUE=Class1>
    <PARAM NAME=CABBASE VALUE=Project1.CAB>
    </OBJECT>
    <!-- Insert HTML here -->
    <FONT color=BLUE>
    <SPAN id="coloredText">Testing...</SPAN>
