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

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.

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
   }
}

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>

Run the project.

RESULT: You will get the following web page:


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