PRB: DhCell.getValue() Returns 0 for DhCell w/o Integer Value

ID: Q196575

The information in this article applies to:

Microsoft Visual J++, version 6.0

SYMPTOMS

The setValue() and setText() APIs set the value of a DhCell.

If setText() is called with a non-integer value, the DhCell is assigned a value of 0.

STATUS

This behavior is by design.

MORE INFORMATION

The value of a DhCell is set by calling either the setValue() or the setText() method.

The following four instructions yield a value of zero because setText is called with a non-integer value:

   DhCell cell=new DhCell(); // Create a DhCell element.
   cell.setValue(10);   // The value of the cell is 10.
   cell.setText("Hello"); // The value of the cell is now 0.
   int cellValue = cell.getValue(); // cellValue=0.

The following four instructions yield a value of 123 because setText is called with an integer value (123):

   DhCell cell=new DhCell(); // Create a DhCell element.
   cell.setValue(10);   // The value of the cell is 10.
   cell.setText("123"); // The value of the cell is now 123.
   int cellValue = cell.getValue(); // cellValue=123.

Steps to Reproduce Behavior

1. Create a default Code-Behind HTML project using Visual J++ 6.0. To do

   this, click New Project... from the File menu. Click the New tab in the
   New Project dialog box. Select Web Pages from the Visual J++ Projects
   tree. Select Code-Behind HTML, and click Open to create the project.
   Class1.java is created by default.

2. 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)
         {
            DhTable table=new DhTable();
            table.setBorder(1);
            add(table);
            DhRow row=new DhRow();
            table.add(row);
            DhRow row2=new DhRow();
            table.add(row2);
            DhCell cell=new DhCell();
            row.add(cell);
            cell.setValue(5);
            row2.add(new DhCell("value:"+cell.getValue()));  // 5

            cell=new DhCell();
            row.add(cell);
            cell.setValue(12);
            cell.setText("HelloWorld");
            row2.add(new DhCell("value:"+cell.getValue()));  // 0

            cell=new DhCell();
            row.add(cell);
            cell.setText("-10");
            row2.add(new DhCell("value:"+cell.getValue()));  // -10

            cell=new DhCell();
            row.add(cell);
            cell.setText("38.3");
            row2.add(new DhCell("value:"+cell.getValue()));  // 0
         }
      }

3. 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>
      </FONT>
      </BODY>
      </HTML>

4. Run the project.

RESULT: You will get the following web page:

   5         HelloWorld    -10          38.3
   value:5   value:0       value:-10    value:0
