FIX: WinIOException Occurs when Calling dumpHTML or dumpDHTML

MORE INFORMATION

Steps to Reproduce Behavior

1. In Visual J++, select New Project from the File menu.
2. In the New Project dialog box, click the New tab.
3. In the Visual J++ Projects tree, click Web Pages.
4. Click Code-Behind HTML.
5. Click Open to create the project.
6. Modify Class1.java as follows:

   import com.ms.wfc.html.*;
   import com.ms.wfc.core.*;
   import com.ms.wfc.ui.*;
   
   public class Class1 extends DhDocument
   {
      public Class1()
      {
         initForm();
      }
      private void initForm()
      {
      }
      protected void onDocumentLoad(Object sender, Event e)
      {
         DhButton button=new DhButton("button");
         add(button);
         this.dumpDHTML(null,null);
   // Workaround1: Uncomment the next line and comment the above line.
   // You must have a "c:\temp" directory or change the directory below.
   //    showHTML("c:\\temp\\");
   
   // Workaround2: Uncomment the next line and comment the above line.
   // You must have a blank.htm in the current directory.
   //    showHTML();
   
      }
   
      public void showHTML(String directory) {
         String filename=directory+"__dump.txt";
         addText(filename);
         com.ms.wfc.io.File outputFile =
           com.ms.wfc.io.File.create(filename);
         writeHTML(outputFile);
         outputFile.close();
         getWindow().open(filename,"dump",null,false);
      }
      public void showHTML() {
         // You must have a "blank.htm" in the current directory
        DhWindow window=getWindow().open("blank.htm","dump",null,false);
        DhDocument document=window.getDocument();
        String x=getHTML();
        document.add(new DhRawHTML(toHTMLViewable(getHTML())));
      }
      static String toHTMLViewable(String text) {
         // indexOf() returns -1 if not found:
         if (text.indexOf('<')+text.indexOf('>')+text.indexOf('&')==-3)
            return text;
         StringBuffer buffer=new StringBuffer(text);
         int index=0;
         String amp="amp;";
         String less="lt;";
         String greater="gt;";
         while (buffer.length()>index) {
            if (buffer.charAt(index)=='&') {
               buffer.insert(index+1,amp);
            } else if (buffer.charAt(index)=='<') {
               buffer.setCharAt(index,'&');
               buffer.insert(index+1,less);
            } else if (buffer.charAt(index)=='>') {
               buffer.setCharAt(index,'&');
               buffer.insert(index+1,greater);
            }
            index++;
         }
         return buffer.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 -->
   </BODY>
   </HTML>
   						

8. Run the project.

RESULT: A WinIOException error occurs. To work around the problem, create an empty Blank.htm file and make sure a C:\Temp directory exists. Comment the call to dumpHTML(). Uncomment the first workaround line if you want to create an output file in the C:\Temp directory and display the results. Uncomment the second workaround if you want to dynamically display the results without writing to the local drive.
